1
00:00:34,690 --> 00:00:39,107
Over the last 250 years
we have, in effect,
2
00:00:39,191 --> 00:00:44,899
conducted the largest
science experiment in history.
3
00:00:44,982 --> 00:00:48,107
Since the advent of
the Industrial Revolution,
4
00:00:48,191 --> 00:00:52,899
we have burned over
1.4 trillion tons of carbon
5
00:00:52,982 --> 00:00:55,149
into the atmosphere.
6
00:00:55,232 --> 00:00:58,441
It has changed life on earth
as we know it,
7
00:00:58,524 --> 00:01:02,232
especially in the Arctic.
8
00:01:02,316 --> 00:01:04,731
The melting of the world's
snow and ice
9
00:01:04,814 --> 00:01:07,940
has now triggered multiple
climate tipping points,
10
00:01:08,024 --> 00:01:12,191
threatening the very existence
of life on earth.
11
00:01:12,274 --> 00:01:17,024
Yet this disturbing future
need not be set in stone.
12
00:01:17,107 --> 00:01:21,024
We have long had alternatives
to fossil fuels.
13
00:01:21,106 --> 00:01:24,274
But more recently,
we have actually discovered
14
00:01:24,358 --> 00:01:27,608
how to pull carbon
out of the atmosphere,
15
00:01:27,690 --> 00:01:32,274
giving us a chance at reversing
climate disruption.
16
00:01:32,358 --> 00:01:35,732
If we are able to reverse
climate change in time,
17
00:01:35,815 --> 00:01:40,899
it would be an unprecedented
achievement in human history.
18
00:01:40,982 --> 00:01:43,274
But the clock is ticking.
19
00:01:43,358 --> 00:01:47,731
Scientists say we must implement
these solutions immediately.
20
00:01:47,814 --> 00:01:50,940
At this critical turning point,
we must give a voice
21
00:01:51,024 --> 00:01:54,358
to the impartial experts
who have presented us
22
00:01:54,441 --> 00:01:58,899
with the facts they have spent
a lifetime to uncover.
23
00:01:58,982 --> 00:02:01,399
It is their time to be heard.
24
00:02:01,483 --> 00:02:05,523
They are the scientists,
researchers and innovators
25
00:02:05,607 --> 00:02:07,649
who have found the solutions
26
00:02:07,732 --> 00:02:12,357
to preserve the very life
of our shared world.
27
00:02:29,231 --> 00:02:31,148
There is a couple
different projects
28
00:02:31,231 --> 00:02:33,940
that require manual sampling.
29
00:02:37,523 --> 00:02:41,065
So one of them
is the long-term CO2 record.
30
00:02:43,690 --> 00:02:45,814
And the way it's set up,
you still need a person
31
00:02:45,898 --> 00:02:49,773
to come physically take
the sample every Tuesday.
32
00:02:51,857 --> 00:02:54,565
I'm the person
that gets to go in the Sno-Cat
33
00:02:54,648 --> 00:02:57,106
to take the measurements.
34
00:02:59,191 --> 00:03:01,066
We want to keep that
long-term record going
35
00:03:01,149 --> 00:03:02,939
the way it's always been taken.
36
00:03:05,065 --> 00:03:08,024
Monitoring and tracking what
we're doing to our atmosphere
37
00:03:08,107 --> 00:03:10,939
is a serious and difficult endeavor.
38
00:03:11,023 --> 00:03:12,773
For the last 50 years,
39
00:03:12,856 --> 00:03:15,482
dedicated researchers
from around the world
40
00:03:15,565 --> 00:03:18,316
travel weekly
to the same locations,
41
00:03:18,399 --> 00:03:21,190
taking samples
of greenhouse gases
42
00:03:21,273 --> 00:03:23,939
that cause climate disruption.
43
00:03:24,023 --> 00:03:28,190
So we're at about 11 and a half
thousand feet at Niwot Ridge
44
00:03:28,273 --> 00:03:31,648
in the front range of the
Rocky Mountains in Colorado.
45
00:03:31,731 --> 00:03:37,648
And this is NOAA's long-term
CO2 sampling site here.
46
00:03:37,731 --> 00:03:39,482
It's the third longest
in the world.
47
00:03:41,398 --> 00:03:43,316
So, these are the flasks
that we're gonna use
48
00:03:43,399 --> 00:03:45,856
to collect our sample,
made out of glass.
49
00:03:45,939 --> 00:03:50,939
And after we're done today filling them
with air, we'll ski 'em down to our office,
50
00:03:51,023 --> 00:03:54,190
and then we'll take them down to NOAA's office
in Boulder where they get analyzed
51
00:03:54,273 --> 00:03:57,065
along with similar flasks
from all over the world.
52
00:03:57,148 --> 00:03:59,523
The reason we do it up here
53
00:03:59,607 --> 00:04:02,065
and a lot of the sampling sites
are high up in the atmosphere
54
00:04:02,148 --> 00:04:03,898
is the air up here
is well mixed
55
00:04:03,981 --> 00:04:07,565
so you're getting a good sample
of the whole atmosphere.
56
00:04:07,648 --> 00:04:09,648
There's the little inlet
on the roof.
57
00:04:09,731 --> 00:04:11,231
When I turn on the pump,
58
00:04:11,315 --> 00:04:15,357
it's gonna suck the air
into these flasks.
59
00:04:15,440 --> 00:04:17,523
This is actually the whole...
60
00:04:17,607 --> 00:04:20,106
carbon cycle
and greenhouse gases,
61
00:04:20,190 --> 00:04:23,190
and CO2 and methane
are the big ones.
62
00:04:25,273 --> 00:04:27,231
When they took the first sample
in 1968,
63
00:04:27,315 --> 00:04:30,231
it measured 322 parts per million.
64
00:04:32,440 --> 00:04:35,648
And now we don't know what
this sample's gonna measure yet,
65
00:04:35,731 --> 00:04:38,648
but it's probably
gonna be around 408.
66
00:04:38,731 --> 00:04:41,773
So, it's a little bit
of an increase.
67
00:04:44,565 --> 00:04:47,440
And now I'm just
putting everything away
68
00:04:47,523 --> 00:04:49,689
and getting it ready
for next week's sample.
69
00:05:05,565 --> 00:05:09,189
One of NOAA's missions
since its inception
70
00:05:09,272 --> 00:05:12,440
was to measure carbon dioxide
in the atmosphere
71
00:05:12,523 --> 00:05:15,856
and other gases
that affect the carbon cycle.
72
00:05:15,939 --> 00:05:18,397
Two samples are collected every week
73
00:05:18,481 --> 00:05:20,398
from around the globe.
74
00:05:20,482 --> 00:05:23,731
So we're looking to see how
these gases change with time.
75
00:05:23,814 --> 00:05:27,356
And the way to do that is
to continuously collect samples.
76
00:05:28,773 --> 00:05:31,648
Currently, we have
about 60 locations.
77
00:05:31,731 --> 00:05:34,772
Most of the samples
are collected in remote areas
78
00:05:34,855 --> 00:05:38,023
away from population centers.
79
00:05:38,106 --> 00:05:40,023
And we measure them
on this set of instruments
80
00:05:40,106 --> 00:05:43,439
for six gases
that affect the carbon cycle.
81
00:05:43,522 --> 00:05:48,689
Those gases are carbon dioxide,
methane, carbon monoxide,
82
00:05:48,773 --> 00:05:51,647
molecular hydrogen,
nitrous oxide
83
00:05:51,730 --> 00:05:53,230
and sulfur hexafluoride.
84
00:05:53,314 --> 00:05:56,856
This system runs five days
and five nights a week,
85
00:05:56,939 --> 00:05:57,981
24 hours a day.
86
00:05:58,065 --> 00:05:59,481
So what I'm doing right now
87
00:05:59,564 --> 00:06:01,397
is putting the air samples
on the manifold
88
00:06:01,481 --> 00:06:03,231
and start the measurements.
89
00:06:03,315 --> 00:06:04,981
And then I can walk away.
90
00:06:30,065 --> 00:06:34,397
I lead NOAA's Global Greenhouse
Gas Reference Network.
91
00:06:34,481 --> 00:06:37,647
The aim of the Global
Greenhouse Gas Reference Network
92
00:06:37,730 --> 00:06:42,064
is to provide data
that are fully calibrated,
93
00:06:42,147 --> 00:06:45,230
carefully quality controlled
and documented.
94
00:06:45,314 --> 00:06:47,231
Data that will still be
fully credible
95
00:06:47,315 --> 00:06:49,607
a hundred years from now
and longer,
96
00:06:49,688 --> 00:06:54,272
so that as climate change
is happening now
97
00:06:54,356 --> 00:06:56,648
and in the future
over the earth,
98
00:06:56,731 --> 00:06:59,564
there will be information
for scientists
99
00:06:59,688 --> 00:07:01,980
that they can really trust
100
00:07:02,064 --> 00:07:04,898
so that they can diagnose
what actually happened
101
00:07:04,981 --> 00:07:09,147
and how climate change
actually happens, how it works.
102
00:07:10,314 --> 00:07:12,855
So modern CO2 measurements
103
00:07:12,938 --> 00:07:15,772
were initiated by Dave Keeling,
104
00:07:15,855 --> 00:07:18,564
a description situation
of oceanography.
105
00:07:18,647 --> 00:07:23,439
Around 1956, he started
measuring along the west coast.
106
00:07:23,522 --> 00:07:28,647
He saw that during
mid-afternoon wherever he was,
107
00:07:28,730 --> 00:07:32,481
he found pretty much the same
concentration everywhere.
108
00:07:32,564 --> 00:07:36,147
And so it got into his head
the idea that maybe
109
00:07:36,230 --> 00:07:37,481
there's something
that we can call
110
00:07:37,564 --> 00:07:38,980
a background concentration.
111
00:07:39,064 --> 00:07:40,938
He started continuous
measurements then
112
00:07:41,022 --> 00:07:43,439
at Mauna Loa Island of Hawaii
113
00:07:43,522 --> 00:07:45,897
and on the coast of Antarctica.
114
00:07:47,439 --> 00:07:50,439
The last ice age
at the end of that glaciation
115
00:07:50,522 --> 00:07:53,189
from 20,000 to 11,000 years ago,
116
00:07:53,272 --> 00:07:56,522
CO2 increased by about 80 ppm
117
00:07:56,606 --> 00:07:59,481
from 200 to 280, roughly.
118
00:07:59,564 --> 00:08:01,147
It was very slow.
119
00:08:01,230 --> 00:08:05,688
It took 6,000 years for CO2
to climb the 80 ppm.
120
00:08:05,772 --> 00:08:07,064
Six thousand years!
121
00:08:09,356 --> 00:08:10,730
In pre-industrial times,
122
00:08:10,813 --> 00:08:12,230
so before 1850,
123
00:08:12,314 --> 00:08:14,938
CO2 was close to 280 ppm.
124
00:08:15,022 --> 00:08:19,105
And now of course
we see 2 ppm per year.
125
00:08:19,189 --> 00:08:24,439
That increase was due 100%
to human activities.
126
00:08:26,189 --> 00:08:28,481
The spike that we now see,
127
00:08:28,564 --> 00:08:32,772
compared to most
geologic history,
128
00:08:32,855 --> 00:08:34,897
I call it an explosion.
129
00:08:36,606 --> 00:08:38,522
It's...
130
00:08:38,606 --> 00:08:43,397
It's like instantaneous
in geologic time scale.
131
00:08:47,064 --> 00:08:49,021
Carbon has increased
dramatically
132
00:08:49,104 --> 00:08:51,189
since the Industrial Revolution.
133
00:08:51,272 --> 00:08:53,980
But what does that
actually mean for all of us?
134
00:08:55,481 --> 00:08:57,355
What we have learned
is that excess carbon
135
00:08:57,438 --> 00:08:59,730
creates climate disruption.
136
00:08:59,813 --> 00:09:03,439
It changes the weather patterns
and life support systems
137
00:09:03,522 --> 00:09:07,897
upon which society
depends to survive.
138
00:09:07,980 --> 00:09:09,730
We have always known
139
00:09:09,813 --> 00:09:12,606
that there's a toxicity
associated with fossil fuels,
140
00:09:12,688 --> 00:09:15,229
but we'd always thought that
it was basically a toxicity
141
00:09:15,313 --> 00:09:16,730
that would affect humans,
142
00:09:16,813 --> 00:09:20,147
you know,
or other individual life forms.
143
00:09:20,230 --> 00:09:22,355
It's really only in the--
144
00:09:22,438 --> 00:09:24,481
within my lifetime certainly
145
00:09:24,564 --> 00:09:27,064
that it has become
frighteningly apparent
146
00:09:27,147 --> 00:09:29,606
that the accumulation
of carbon in the atmosphere
147
00:09:29,688 --> 00:09:31,854
has caused it to warm up.
148
00:09:31,937 --> 00:09:34,564
This greenhouse effect,
this toxicity,
149
00:09:34,647 --> 00:09:39,104
impacts the life systems
of the planet as a whole.
150
00:09:39,188 --> 00:09:42,813
And, you know, once I got that
back in the mid-90s,
151
00:09:42,897 --> 00:09:44,397
I had to start talking about it
152
00:09:44,481 --> 00:09:46,481
and we've been
talking about it ever since.
153
00:09:51,230 --> 00:09:54,813
When we talk about
dangerous planetary warming,
154
00:09:54,897 --> 00:09:59,481
we're referring to something
akin to a two degree Celsius,
155
00:09:59,564 --> 00:10:02,230
that's about three and a half
degree Fahrenheit
156
00:10:02,314 --> 00:10:05,271
warming of the planet relative
to pre-industrial times.
157
00:10:05,355 --> 00:10:08,272
That is where we start to see
some of the worst
158
00:10:08,356 --> 00:10:12,104
and potentially irreversible
impacts of climate change:
159
00:10:12,188 --> 00:10:13,771
substantial melting
of the ice sheets
160
00:10:13,854 --> 00:10:17,439
and associated substantial rise
in sea level,
161
00:10:17,522 --> 00:10:19,938
permanent droughts
in mid-latitudes,
162
00:10:20,022 --> 00:10:23,438
and the list goes on.
163
00:10:23,521 --> 00:10:27,439
Well, catastrophic would be
we melt the major ice sheets,
164
00:10:27,522 --> 00:10:30,313
the Greenland ice sheet
and the West Antarctic ice sheet
165
00:10:30,396 --> 00:10:35,314
as all the major coastal cities
of the world are flooded.
166
00:10:35,397 --> 00:10:37,146
You've got less land.
167
00:10:37,229 --> 00:10:39,104
You've got environmental refugees,
168
00:10:39,188 --> 00:10:41,646
some people leaving those regions.
169
00:10:41,729 --> 00:10:44,189
People leaving the tropics
because it's getting too hot
170
00:10:44,272 --> 00:10:46,146
for human habitation.
171
00:10:46,229 --> 00:10:49,104
It's getting too hot
for agriculture.
172
00:10:49,188 --> 00:10:52,730
Crops in the tropics
will decrease dramatically
173
00:10:52,813 --> 00:10:54,480
in their productivity.
174
00:10:54,563 --> 00:10:58,313
In short, you're looking
at a world with less land,
175
00:10:58,396 --> 00:11:02,147
less food, less water
and more people.
176
00:11:02,230 --> 00:11:06,563
And that's a recipe for
a national security disaster.
177
00:11:20,063 --> 00:11:21,521
I work on the carbon cycle,
178
00:11:21,605 --> 00:11:25,480
tasks that I've taken on
for more than 30 years
179
00:11:25,563 --> 00:11:27,356
and truth be told,
I figured
180
00:11:27,439 --> 00:11:30,521
we would have done something
about this 20 years ago
181
00:11:30,605 --> 00:11:31,979
and I could be off
doing something else,
182
00:11:32,063 --> 00:11:33,812
but I'm still doing
what I'm doing.
183
00:11:36,771 --> 00:11:38,438
If you think about
the relationship
184
00:11:38,521 --> 00:11:40,355
between carbon dioxide
and sea level,
185
00:11:40,438 --> 00:11:43,355
there's a couple of interesting
points in that relationship.
186
00:11:43,438 --> 00:11:48,271
One of them is when CO2 goes up
to roughly 400 parts per million.
187
00:11:48,355 --> 00:11:53,020
That is warm enough that we
melt off chunks of Antarctica,
188
00:11:53,103 --> 00:11:54,771
chunks of Greenland.
189
00:11:54,854 --> 00:11:56,854
And those chunks
are the chunks that are
190
00:11:56,937 --> 00:11:58,438
what we call marine base.
191
00:11:58,521 --> 00:12:00,812
So the base of the ice sheet
in West Antarctica
192
00:12:00,896 --> 00:12:04,104
is below sea level because
it's pinned to the sediments.
193
00:12:04,188 --> 00:12:05,521
And once it starts to melt,
194
00:12:05,605 --> 00:12:07,188
it's one of these
freight trains.
195
00:12:07,271 --> 00:12:09,438
We don't know how this thing
is gonna stop.
196
00:12:11,063 --> 00:12:14,854
And we're dangerously
at that point right now.
197
00:12:18,063 --> 00:12:19,646
The other threshold
is somewhere around
198
00:12:19,729 --> 00:12:22,812
six to seven hundred
parts per million CO2.
199
00:12:22,896 --> 00:12:26,521
That's warm enough
that there is no more ice,
200
00:12:26,605 --> 00:12:28,103
land ice on the planet.
201
00:12:28,187 --> 00:12:31,812
And you have about
80 meters higher sea level.
202
00:12:33,937 --> 00:12:35,936
We are on our way
203
00:12:36,020 --> 00:12:38,812
to six, seven hundred
parts per million.
204
00:12:41,771 --> 00:12:45,187
But I think that's one of those
interesting threshold moments
205
00:12:45,270 --> 00:12:48,729
in our relationship
with the planet where,
206
00:12:48,812 --> 00:12:52,770
are we gonna push
the climate system
207
00:12:52,853 --> 00:12:55,188
so far out of balance
208
00:12:55,271 --> 00:12:59,146
that we threaten the melting
of all land ice?
209
00:13:10,312 --> 00:13:11,936
Guomundur Ingi Guobrandsson:
Yeah, it has changed.
210
00:13:12,020 --> 00:13:14,854
Icelandic nature
is experiencing change
211
00:13:14,937 --> 00:13:16,646
because of climate change.
212
00:13:16,729 --> 00:13:20,312
This is quite visible in
the south coast, for example.
213
00:13:20,395 --> 00:13:23,438
Our largest glacier,
Glacier Vatnajokull
214
00:13:23,521 --> 00:13:26,645
or Water Glacier
if you translate it directly,
215
00:13:26,728 --> 00:13:29,145
has also retreated quite a lot.
216
00:13:29,228 --> 00:13:32,229
There is one
very interesting observation
217
00:13:32,313 --> 00:13:36,645
that everybody noticed when
they drive the south coast now
218
00:13:36,728 --> 00:13:40,146
and that is that they drive over
the longest bridge in Iceland,
219
00:13:40,229 --> 00:13:42,271
almost one kilometer in length,
220
00:13:42,355 --> 00:13:45,479
and there is
almost no water under it.
221
00:13:45,562 --> 00:13:50,605
So you think, OK,
why building such a big bridge
222
00:13:50,687 --> 00:13:52,395
for almost no water?
223
00:13:54,604 --> 00:13:58,563
Well, this is just climate change.
224
00:13:58,646 --> 00:14:01,145
The river changed its course
225
00:14:01,228 --> 00:14:04,395
is because of the retreat
of the glacier.
226
00:14:07,271 --> 00:14:11,936
So now we have
this sort of monument,
227
00:14:12,020 --> 00:14:15,729
a symbolic thing of the past.
228
00:14:30,103 --> 00:14:35,354
The Arctic is a profoundly
different place right now.
229
00:14:35,437 --> 00:14:39,062
In the Arctic,
the impacts of climate change
230
00:14:39,145 --> 00:14:41,562
are the most extreme.
231
00:14:41,645 --> 00:14:45,479
What scientists are finding is
that what happens in the Arctic
232
00:14:45,562 --> 00:14:49,729
has major impacts
for the rest of the planet.
233
00:14:49,812 --> 00:14:52,479
I am working with measuring
greenhouse gases
234
00:14:52,562 --> 00:14:54,062
at the Arctic location
235
00:14:54,145 --> 00:14:56,395
and understanding how
the greenhouse gases
236
00:14:56,479 --> 00:14:58,686
are changing over time.
237
00:14:58,770 --> 00:15:02,103
I am concerned about the increase
of temperature in the Arctic
238
00:15:02,187 --> 00:15:06,605
and the impact this might have
on all the Arctic systems.
239
00:15:06,687 --> 00:15:09,645
But what I think is extremely
important to be aware of
240
00:15:09,728 --> 00:15:14,228
is that with the sea ice reduction
we have now
241
00:15:14,312 --> 00:15:15,936
and all the other changes,
242
00:15:16,020 --> 00:15:18,604
you might change
the whole weather system,
243
00:15:18,686 --> 00:15:20,520
and this has global impact.
244
00:15:22,270 --> 00:15:24,853
We know that the changes
that we see in Arctic
245
00:15:24,936 --> 00:15:27,853
does not only stay
in the Arctic.
246
00:15:31,437 --> 00:15:33,270
Yeah, I've been
working on sea ice
247
00:15:33,354 --> 00:15:35,062
the last 50 years pretty much.
248
00:15:35,145 --> 00:15:39,686
And the whole Arctic has changed
so much in that time.
249
00:15:39,770 --> 00:15:44,103
Loss of ice, loss of not only
a loss of area of ice,
250
00:15:44,187 --> 00:15:45,728
but the loss of the appearance
251
00:15:45,811 --> 00:15:48,604
of the great ice fields
of the past
252
00:15:48,686 --> 00:15:52,062
with huge pressure ridges
and very, very thick ice.
253
00:15:52,145 --> 00:15:56,479
Really dramatic ice scenery
has all gone.
254
00:15:58,853 --> 00:16:01,728
Last month I was up
in the Barents Sea
255
00:16:01,811 --> 00:16:04,062
on a research cruise
in a region where
256
00:16:04,145 --> 00:16:07,019
normally you would have
quite a lot of multiyear ice.
257
00:16:07,102 --> 00:16:08,895
We couldn't find
any multiyear ice.
258
00:16:15,894 --> 00:16:20,145
So the ice was all very thin,
30 centimeters thick.
259
00:16:20,228 --> 00:16:23,478
The Arctic Ocean is no longer
a continent of ice
260
00:16:23,561 --> 00:16:26,312
but something that becomes
just water in summer.
261
00:16:26,395 --> 00:16:31,727
There is a real, a huge loss
as far as beauty is concerned,
262
00:16:31,810 --> 00:16:36,770
but also as far as the physics
of how the planet operates.
263
00:16:36,853 --> 00:16:39,644
The ice is disappearing
because the climate's warming,
264
00:16:39,727 --> 00:16:41,977
that's pretty obvious
that will happen,
265
00:16:42,061 --> 00:16:44,354
but there's much more to it
than that,
266
00:16:44,437 --> 00:16:46,270
because in fact you have
267
00:16:46,354 --> 00:16:48,685
many other feedback mechanisms
going on
268
00:16:48,769 --> 00:16:50,810
which cause the effects
on the planet
269
00:16:50,894 --> 00:16:54,270
to be far worse than just
the retreat of the ice.
270
00:16:57,061 --> 00:16:58,561
So the Arctic's warming up
271
00:16:58,644 --> 00:17:00,604
three times faster
than the rest of the world
272
00:17:00,686 --> 00:17:02,103
and the temperature difference
273
00:17:02,187 --> 00:17:04,562
between the Arctic
and lower latitudes
274
00:17:04,645 --> 00:17:06,894
is getting less,
and that means
275
00:17:06,977 --> 00:17:10,020
that the jet stream
is getting to be weaker.
276
00:17:10,103 --> 00:17:11,562
And as it gets weaker,
277
00:17:11,645 --> 00:17:14,019
it goes from being
almost a straight line
278
00:17:14,102 --> 00:17:19,770
to becoming big lobes
reaching up north and south.
279
00:17:19,853 --> 00:17:21,603
And with it,
when you have a lobe like that,
280
00:17:21,685 --> 00:17:23,935
it means that polar air
can come down
281
00:17:24,019 --> 00:17:28,228
to lower latitudes than it
normally reaches in one sector,
282
00:17:28,312 --> 00:17:30,769
and then in the sector
to the east or west of it,
283
00:17:30,852 --> 00:17:33,353
you've got warm air
going up north
284
00:17:33,436 --> 00:17:34,978
further than it should do.
285
00:17:35,062 --> 00:17:37,395
So you're getting
bizarre weather extremes
286
00:17:37,479 --> 00:17:39,727
which of course everybody's
been commenting on.
287
00:17:39,810 --> 00:17:41,519
The trouble is where
these air masses
288
00:17:41,603 --> 00:17:44,562
are causing such extreme changes
289
00:17:44,645 --> 00:17:46,354
happens to be the latitudes
290
00:17:46,437 --> 00:17:49,519
at which you have
the maximum food production.
291
00:17:49,603 --> 00:17:51,603
Suddenly our ability
to feed everyone
292
00:17:51,685 --> 00:17:55,519
is being affected
by these polar changes.
293
00:17:57,394 --> 00:17:59,394
You can't take
that amount of ice away
294
00:17:59,478 --> 00:18:02,145
without affecting
so many other things.
295
00:18:13,769 --> 00:18:17,810
The impact of our actions
are starting to hit home.
296
00:18:17,894 --> 00:18:20,603
Scientists' predictions
are now coming true
297
00:18:20,685 --> 00:18:22,353
sooner than expected.
298
00:18:22,436 --> 00:18:25,935
We are tragically suffering
through severe storms,
299
00:18:26,019 --> 00:18:28,686
droughts, floods and fires
300
00:18:28,770 --> 00:18:31,727
that are progressively becoming
more intense
301
00:18:31,810 --> 00:18:33,186
and more unpredictable.
302
00:19:17,311 --> 00:19:20,436
Fires started
almost simultaneously
303
00:19:20,519 --> 00:19:22,353
in multiple places.
304
00:19:24,186 --> 00:19:27,852
Over 7,000 structures
were destroyed
305
00:19:27,935 --> 00:19:29,977
and about 3,000 homes.
306
00:19:30,061 --> 00:19:33,102
I think at the height
in the early days of the fire,
307
00:19:33,186 --> 00:19:38,603
maybe about 100,000 people
were evacuated.
308
00:19:38,685 --> 00:19:42,102
It's a collective trauma.
309
00:19:44,311 --> 00:19:47,269
Sounded like a war zone,
looked like a war zone.
310
00:19:47,353 --> 00:19:50,144
They talk about the Hanley Fire,
it took a day to get here.
311
00:19:50,227 --> 00:19:53,019
It burned about the same footprint,
but it took about a day.
312
00:19:53,102 --> 00:19:55,478
It burned less than
200 structures.
313
00:19:55,561 --> 00:19:57,144
This fire started at night,
314
00:19:57,227 --> 00:19:59,935
made it to Santa Rosa in four,
four and a half hours,
315
00:20:00,019 --> 00:20:02,809
and there's no comparison
other than the footprint.
316
00:20:02,893 --> 00:20:04,269
Cal Fire Incident Management Team
317
00:20:04,353 --> 00:20:06,935
came here to help run this incident
318
00:20:07,019 --> 00:20:08,644
and he just shook his head
and said,
319
00:20:08,727 --> 00:20:10,310
"Man, I've never seen
anything like this.
320
00:20:10,393 --> 00:20:12,519
I've been doing this
a long time."
321
00:20:12,644 --> 00:20:15,603
So that's not
terribly comforting,
322
00:20:15,685 --> 00:20:19,560
but that's where we're at
right now.
323
00:20:19,643 --> 00:20:21,143
If we keep having
these wind events,
324
00:20:21,227 --> 00:20:22,644
how do we protect our citizens?
325
00:20:22,727 --> 00:20:24,561
How do we protect
our infrastructure?
326
00:20:24,644 --> 00:20:26,311
What are the things
that we can do
327
00:20:26,394 --> 00:20:29,226
to make it as good as possible?
328
00:20:29,310 --> 00:20:32,561
We've been through four,
five years of drought.
329
00:20:32,644 --> 00:20:35,684
That drought stresses
all the brush, all the trees.
330
00:20:35,768 --> 00:20:40,061
And the winds at Geyser Peak
on one of the weather station
331
00:20:40,144 --> 00:20:43,394
was clocked at
108 miles an hour.
332
00:20:43,478 --> 00:20:45,226
And I don't know what you do
with those kinds of winds.
333
00:20:45,310 --> 00:20:47,727
When something catches on fire,
334
00:20:47,810 --> 00:20:50,727
it's all you can do to try
to figure out where it's going
335
00:20:50,810 --> 00:20:52,435
and how fast
it's gonna get there.
336
00:20:55,851 --> 00:20:57,519
I never would have thought
a fire
337
00:20:57,603 --> 00:21:00,768
would come out of the hills
and run the flats in Santa Rosa.
338
00:21:00,851 --> 00:21:01,851
I really didn't.
339
00:21:03,851 --> 00:21:05,394
Cars were being flipped over.
340
00:21:05,478 --> 00:21:10,060
There were shoebox chunks
of, you know, embers
341
00:21:10,143 --> 00:21:13,477
that were being carried
well ahead of the fire.
342
00:21:13,560 --> 00:21:15,311
You'll see there's some trees
343
00:21:15,394 --> 00:21:17,353
where all the limbs are just,
they're snapped off.
344
00:21:17,436 --> 00:21:19,643
They're not burned off,
they're snapped off.
345
00:21:22,185 --> 00:21:25,478
These natural disasters
are so common now
346
00:21:25,561 --> 00:21:28,934
that people know it's gonna
happen to their community.
347
00:21:29,018 --> 00:21:33,436
It's not like a matter of if,
but when.
348
00:21:33,519 --> 00:21:36,726
It is a wake-up call
to everyone
349
00:21:36,809 --> 00:21:39,310
that climate change is here
350
00:21:39,393 --> 00:21:42,102
and that you need
to plan for it.
351
00:21:47,934 --> 00:21:53,101
Climate disruption is causing
a rise in extinctions today,
352
00:21:53,185 --> 00:21:56,393
but this isn't the first time.
353
00:21:56,477 --> 00:22:00,226
Scientists studying
geological records have shown
354
00:22:00,310 --> 00:22:03,851
there is a connection
between spikes in carbon
355
00:22:03,934 --> 00:22:07,019
and the past five
mass extinctions.
356
00:22:09,018 --> 00:22:10,934
There is a natural law
357
00:22:11,018 --> 00:22:15,810
that the carbon cycle
affects the fabric of life.
358
00:22:15,894 --> 00:22:19,435
Every time there has been
a massive increase in carbon,
359
00:22:19,518 --> 00:22:24,934
the web of life weakens
and sometimes collapses.
360
00:22:30,684 --> 00:22:35,435
I've been working on the way
in which the carbon cycle
361
00:22:35,518 --> 00:22:38,851
is associated with the
occurrence of mass extinctions
362
00:22:38,934 --> 00:22:43,602
and whether the carbon cycle can undergo
instabilities associated with them.
363
00:22:45,268 --> 00:22:48,185
So the carbon cycle
is where life
364
00:22:48,268 --> 00:22:50,393
and the environment interact.
365
00:22:50,477 --> 00:22:54,018
You can think of it as one grand loop
between photosynthesis,
366
00:22:54,101 --> 00:22:58,018
which is a process that takes carbon dioxide
out of the atmosphere
367
00:22:58,101 --> 00:23:03,393
and converts it to oxygen
and plant matter or organic carbon.
368
00:23:03,477 --> 00:23:06,435
And then the back reaction
of the loop we call respiration
369
00:23:06,518 --> 00:23:11,809
which is the process via which we convert
that plant matter to carbon dioxide.
370
00:23:13,809 --> 00:23:16,560
The grand loop of
the carbon cycle takes about
371
00:23:16,643 --> 00:23:20,643
a hundred gigaton of carbon out of
the atmosphere and oceans every year
372
00:23:20,726 --> 00:23:22,560
and it returns it each year.
373
00:23:22,643 --> 00:23:24,392
So this is a hundred gigatons out
374
00:23:24,476 --> 00:23:26,893
and a hundred gigatons back in.
375
00:23:26,976 --> 00:23:31,518
But what we're contributing is on the order
of about 8% from fossil fuel burning.
376
00:23:31,602 --> 00:23:36,768
It's an 8% increase compared to what is normally
going back and forth in a year.
377
00:23:36,851 --> 00:23:41,184
It turns out to be more than what volcanoes
are putting into the system.
378
00:23:53,435 --> 00:23:57,435
The planet is constantly
in the process
379
00:23:57,518 --> 00:24:00,893
of rebalancing its cycles,
like its water cycle
380
00:24:00,976 --> 00:24:03,101
and its nitrogen cycle
and its carbon cycle.
381
00:24:03,185 --> 00:24:06,683
You've gotta think of it
as it's in constant flow.
382
00:24:06,767 --> 00:24:09,851
And part of the planet's
doing that, you know,
383
00:24:09,934 --> 00:24:15,392
was to take all the carbon that was
in the dinosaurs and land plants
384
00:24:15,476 --> 00:24:21,268
and press that into
eventually oil and fossil fuels.
385
00:24:21,352 --> 00:24:24,267
Over long periods of time
it was sequestered
386
00:24:24,351 --> 00:24:27,477
and we're a young species.
387
00:24:27,560 --> 00:24:31,808
And we were curious
and we dug up the carbon
388
00:24:31,892 --> 00:24:35,393
that had been sequestered
by the earth.
389
00:24:35,477 --> 00:24:39,143
And we burned it,
not knowing it was like
390
00:24:39,226 --> 00:24:43,683
burning furniture in a house
with its windows closed.
391
00:24:44,893 --> 00:24:46,310
So what's happened
392
00:24:46,393 --> 00:24:49,225
is that the planet
is reeling from that.
393
00:24:49,309 --> 00:24:53,643
There's an excess of carbon
up in the atmosphere.
394
00:24:53,726 --> 00:24:58,725
What it's doing is causing
the living conditions
395
00:24:58,808 --> 00:25:02,518
here on earth
to go out of balance.
396
00:25:02,602 --> 00:25:06,559
So as a biologist,
when I look at climate change,
397
00:25:06,642 --> 00:25:11,893
yes, I look at rising seas
and melting polar caps.
398
00:25:11,976 --> 00:25:14,017
Those are evidence for me.
399
00:25:14,100 --> 00:25:19,435
But when we begin to look at
what's happening
400
00:25:19,518 --> 00:25:24,850
to the biological organisms in
response to the warming trends,
401
00:25:24,933 --> 00:25:27,142
they are already on the move.
402
00:25:27,225 --> 00:25:31,683
They're moving towards
the poles to get cooler.
403
00:25:31,767 --> 00:25:35,850
They're moving from the lower mountains
up in elevation,
404
00:25:35,933 --> 00:25:39,517
meaning their ranges are moving.
405
00:25:39,601 --> 00:25:43,683
They also sometimes move
without their helpers.
406
00:25:43,767 --> 00:25:46,809
A plant will move north and its
pollinator won't make it.
407
00:25:46,893 --> 00:25:49,892
This is called in our
bloodless language of science,
408
00:25:49,975 --> 00:25:53,517
it's called ecological disruptions.
409
00:25:55,642 --> 00:25:58,808
So for me, if we change
the very conditions
410
00:25:58,892 --> 00:26:01,892
that gave rise to all of this,
411
00:26:01,975 --> 00:26:06,476
and to us, we--
412
00:26:07,517 --> 00:26:09,142
It's gonna get crazy.
413
00:26:12,310 --> 00:26:14,392
When the carbon cycle
is unstable,
414
00:26:14,476 --> 00:26:18,975
it moves into a realm
that we don't understand.
415
00:26:19,059 --> 00:26:21,892
Going back to geologic time
is that occasionally
416
00:26:21,975 --> 00:26:25,725
there are these essentially
bursts within the carbon cycle
417
00:26:25,808 --> 00:26:27,642
in which things change.
418
00:26:30,601 --> 00:26:32,100
One of them which is widely known
419
00:26:32,184 --> 00:26:34,933
as the Paleocene Eocene
Thermal Maxima
420
00:26:35,017 --> 00:26:36,850
55 million years ago.
421
00:26:38,975 --> 00:26:42,017
And others which are decidedly worse.
422
00:26:42,100 --> 00:26:43,767
They're destructive
or catastrophic events.
423
00:26:43,850 --> 00:26:45,392
They're mass extinctions.
424
00:26:45,476 --> 00:26:48,059
The worst of them known as
the Permian Extinction.
425
00:26:51,476 --> 00:26:52,975
So that's the historical record
426
00:26:53,059 --> 00:26:54,891
but what we're doing
to the carbon cycle now
427
00:26:54,974 --> 00:26:56,601
is another kind of problem
428
00:26:56,683 --> 00:26:58,850
because now we know
what's going on.
429
00:26:58,933 --> 00:27:03,224
We know that we have been adding
carbon dioxide
430
00:27:03,308 --> 00:27:05,100
as a consequence
of fossil fuels.
431
00:27:05,184 --> 00:27:07,434
And then the question is,
does that risk
432
00:27:07,517 --> 00:27:10,476
engendering the kind of bursts
that we've seen in the past
433
00:27:10,559 --> 00:27:11,974
that could create
what I would call
434
00:27:12,058 --> 00:27:14,767
an instability
in the carbon cycle?
435
00:27:14,850 --> 00:27:17,559
That is one in which small changes
436
00:27:17,642 --> 00:27:19,476
become bigger changes.
437
00:27:19,559 --> 00:27:23,225
That's a precise scientists'
definition of catastrophe.
438
00:27:24,725 --> 00:27:26,975
When you get down
to the individual level,
439
00:27:27,059 --> 00:27:29,766
losing one's home to a flood
is a catastrophe.
440
00:28:50,975 --> 00:28:52,849
We can still avoid
441
00:28:52,932 --> 00:28:55,391
breaching that dangerous limit
of two degrees,
442
00:28:55,475 --> 00:28:56,891
but if you do the math,
443
00:28:56,974 --> 00:28:59,601
with each passing year
of relative inaction,
444
00:28:59,683 --> 00:29:01,682
it's getting
more and more difficult
445
00:29:01,766 --> 00:29:03,807
to limit our carbon emissions
446
00:29:03,891 --> 00:29:07,434
and remain under
two degrees Celsius warming.
447
00:30:17,433 --> 00:30:21,183
We know we have put too much
carbon into the atmosphere.
448
00:30:21,266 --> 00:30:23,891
But how much is too much?
449
00:30:23,974 --> 00:30:26,974
Scientists have figured out
what that amount is
450
00:30:27,058 --> 00:30:29,141
and have created
a carbon budget
451
00:30:29,224 --> 00:30:32,974
that will create
a margin for life.
452
00:30:33,058 --> 00:30:35,807
This budget tells us
where we are now,
453
00:30:35,891 --> 00:30:38,058
how much more carbon
we can burn
454
00:30:38,141 --> 00:30:40,350
and how much
needs to be removed
455
00:30:40,433 --> 00:30:44,766
in order to sustain life
on earth as we know it.
456
00:30:48,433 --> 00:30:50,141
I would say the major challenge
457
00:30:50,224 --> 00:30:53,224
is indeed dangerous climate change.
458
00:30:53,308 --> 00:30:57,433
And if we want to avoid
dangerous climate change,
459
00:30:57,516 --> 00:31:00,682
well, then we have to accept
that the atmosphere
460
00:31:00,766 --> 00:31:03,974
is for humankind
a limiting disposal space.
461
00:31:04,058 --> 00:31:09,015
So roughly we can emit
800 gigatons CO2
462
00:31:09,098 --> 00:31:12,391
into the atmosphere in this
limiting disposal space.
463
00:31:12,475 --> 00:31:16,182
And if you take into account
that over the last five years
464
00:31:16,265 --> 00:31:19,058
we have already used 200 gigatons,
465
00:31:19,141 --> 00:31:23,016
so this basically means
that over the next two decades
466
00:31:23,099 --> 00:31:27,224
we have exhausted
the limiting disposal space.
467
00:31:27,308 --> 00:31:30,224
So in Paris
it was very important
468
00:31:30,308 --> 00:31:33,057
that the whole world
and the whole world leaders
469
00:31:33,140 --> 00:31:36,724
agreed on limiting
temperature increase
470
00:31:36,807 --> 00:31:38,558
to well below two degrees.
471
00:31:38,641 --> 00:31:40,891
So that's the kind of safeguard line
472
00:31:40,974 --> 00:31:42,349
and it's very important that
473
00:31:42,432 --> 00:31:45,141
more than a hundred nations
stand behind it.
474
00:31:45,224 --> 00:31:47,932
So imagine the volume
that is in this ball.
475
00:31:48,016 --> 00:31:50,640
That's a kind of symbol
for the CO2
476
00:31:50,723 --> 00:31:54,932
that is still in the ground
in terms of coal
477
00:31:55,016 --> 00:31:57,558
or in the form of oil and gas.
478
00:31:57,641 --> 00:32:00,515
So this is the amount of carbon.
479
00:32:00,599 --> 00:32:03,807
And if we want
to limit the temperature
480
00:32:03,891 --> 00:32:07,015
to two degrees globally,
we may only emit
481
00:32:07,098 --> 00:32:10,974
this little amount of carbon
into the atmosphere.
482
00:32:11,058 --> 00:32:14,308
And to see that we have
a lot more of carbon
483
00:32:14,391 --> 00:32:18,182
still stored in the ground that
we can emit in the atmosphere
484
00:32:18,265 --> 00:32:21,266
when we want to limit
the temperature to two degrees.
485
00:32:21,350 --> 00:32:24,057
So therefore the question is,
how does it fit together?
486
00:32:24,140 --> 00:32:26,806
So, now for the next 20 years,
487
00:32:26,890 --> 00:32:29,266
this is an enormous
important time span
488
00:32:29,350 --> 00:32:31,308
to transform our economies,
489
00:32:31,391 --> 00:32:34,848
to decouple economic growth
from emission growth.
490
00:32:34,931 --> 00:32:39,058
And by middle of the century,
we need zero emissions,
491
00:32:39,141 --> 00:32:44,140
and after 2050 you need
even negative emissions.
492
00:32:44,223 --> 00:32:47,641
The carbon clock is just informing people
where we are now.
493
00:32:47,724 --> 00:32:50,931
What is the pathway
how we exhaust
494
00:32:51,015 --> 00:32:54,475
the limiting disposal space
of the atmosphere.
495
00:32:54,558 --> 00:32:57,265
And this is a huge challenge
for humankind.
496
00:33:08,681 --> 00:33:11,974
Science tells us that
our current climate crisis
497
00:33:12,058 --> 00:33:14,681
is a problem we've created.
498
00:33:14,765 --> 00:33:17,765
But it is also a problem
we can fix.
499
00:33:17,848 --> 00:33:21,641
Not only do we need to stop emitting
carbon at the current levels
500
00:33:21,724 --> 00:33:24,057
by switching to renewable energy,
501
00:33:24,140 --> 00:33:29,308
but it is also critical to pull
carbon out of the atmosphere.
502
00:33:29,391 --> 00:33:34,848
Climate change can be reversed
if we act now.
503
00:33:34,931 --> 00:33:38,016
Recently researchers have
figured out what solutions
504
00:33:38,099 --> 00:33:43,140
can draw carbon down, getting us
back to pre-industrial levels.
505
00:33:46,265 --> 00:33:49,390
There's only two things you
can do about the atmosphere.
506
00:33:49,474 --> 00:33:52,223
You can either stop putting
greenhouse gases up there
507
00:33:52,307 --> 00:33:55,223
or you can bring CO2 back down.
That's it.
508
00:33:55,307 --> 00:33:57,515
And you can do the first one
by conservation,
509
00:33:57,599 --> 00:34:00,140
energy efficiency
and clean energy.
510
00:34:00,223 --> 00:34:02,765
And the second one through
photosynthesis,
511
00:34:02,848 --> 00:34:07,599
whether it's on land, on farms,
on forests, phytoplankton,
512
00:34:07,681 --> 00:34:10,390
kelp in the oceans; there's only
two things you can do.
513
00:34:10,474 --> 00:34:13,432
So that actually
sorts it pretty simply.
514
00:34:13,515 --> 00:34:17,723
And in the past what has
been done in terms of solutions
515
00:34:17,806 --> 00:34:20,057
is that it's focused on energy.
516
00:34:20,140 --> 00:34:22,015
Energy, energy, energy.
517
00:34:22,098 --> 00:34:24,057
And the reason for that
is understandable.
518
00:34:24,140 --> 00:34:25,848
So it makes perfect sense to say,
519
00:34:25,931 --> 00:34:29,140
"Well, let's stop putting
that CO2 up there,"
520
00:34:29,223 --> 00:34:32,723
excepting that in the process
of emphasizing clean energy,
521
00:34:32,806 --> 00:34:35,349
renewable energy, solar,
wind, et cetera,
522
00:34:35,432 --> 00:34:39,973
it's sort of occluded
the rest of the solutions.
523
00:34:49,015 --> 00:34:51,015
The purpose of Drawdown
is to see
524
00:34:51,098 --> 00:34:54,765
if the 80 solutions
that we had modeled
525
00:34:54,847 --> 00:34:58,723
would scale to the point where
we could reverse global warming
526
00:34:58,806 --> 00:35:00,557
within 30 years,
527
00:35:00,640 --> 00:35:03,348
going from reduce to reverse.
528
00:35:03,431 --> 00:35:05,014
The bend the carbon curve,
529
00:35:05,097 --> 00:35:08,057
what Drawdown shows,
is that we have choices.
530
00:35:08,140 --> 00:35:13,348
And that if we increase the rate that
we're scaling some of the solutions,
531
00:35:13,431 --> 00:35:16,474
then we could achieve Drawdown
at 2050.
532
00:35:18,265 --> 00:35:21,264
And if you say
the odds are long,
533
00:35:21,348 --> 00:35:23,640
I agree, they're long odds.
534
00:35:23,723 --> 00:35:25,640
I'll take 'em.
535
00:35:54,181 --> 00:35:55,972
My name is Linwood Gill.
536
00:35:56,056 --> 00:35:59,557
I'm the Chief Forester for the
Usal Redwood Forest Company.
537
00:36:00,890 --> 00:36:04,306
Usal Redwood Forest
is a community forest,
538
00:36:04,389 --> 00:36:07,890
it's owned by a non-profit,
the Redwood Forest Foundation.
539
00:36:07,973 --> 00:36:10,098
It's a 50,000 acre forest
540
00:36:10,182 --> 00:36:14,139
which is dedicated
to managing the forest
541
00:36:14,222 --> 00:36:15,723
on a long-term basis
542
00:36:15,806 --> 00:36:18,182
for the economic stability
of the community,
543
00:36:18,265 --> 00:36:21,431
as well as restoring
the forest habitat,
544
00:36:21,514 --> 00:36:24,014
restoring the fish habitat,
545
00:36:24,097 --> 00:36:26,349
and also for sequestering carbon.
546
00:36:26,432 --> 00:36:32,348
And carbon sequestration is a main part
of our operations right now.
547
00:36:32,431 --> 00:36:35,015
Carbon sequestration
is an important part
548
00:36:35,098 --> 00:36:37,680
of combatting climate change.
549
00:36:37,764 --> 00:36:41,848
The Usal Redwood Forest is
a very young redwood forest.
550
00:36:41,931 --> 00:36:45,598
and redwoods can absorb
more carbon
551
00:36:45,680 --> 00:36:47,930
than any other forest type
on the planet.
552
00:36:49,639 --> 00:36:51,140
Redwoods store carbon
553
00:36:51,223 --> 00:36:54,930
by absorbing carbon
from carbon dioxide
554
00:36:55,014 --> 00:36:57,181
out of the air into its needles
555
00:36:57,264 --> 00:36:59,474
and stores it into
the bowl of the tree,
556
00:36:59,557 --> 00:37:02,805
the trunk or the roots,
the branches.
557
00:37:02,889 --> 00:37:04,639
To my knowledge,
558
00:37:04,722 --> 00:37:06,639
this is one of
the largest carbon projects
559
00:37:06,722 --> 00:37:08,681
in the country, yes.
560
00:37:16,139 --> 00:37:19,056
I am the Biochar
Project Manager
561
00:37:19,139 --> 00:37:21,431
for the Redwood Forest Foundation.
562
00:37:21,514 --> 00:37:25,139
We're sort of at a perfect
storm right now in California
563
00:37:25,222 --> 00:37:29,431
where we have over a hundred million
dead trees in the Sierra.
564
00:37:29,514 --> 00:37:32,306
And we need to do something
with that.
565
00:37:34,222 --> 00:37:36,889
We have what is called
the western pine bark beetle,
566
00:37:36,972 --> 00:37:41,972
which makes its living by feeding
on ponderosa pine, and other trees as well.
567
00:37:43,722 --> 00:37:46,473
And these beetles have been
around for thousands of years
568
00:37:46,556 --> 00:37:50,139
and have lived in harmony
and balance with the trees.
569
00:37:50,222 --> 00:37:52,556
But unfortunately,
because of climate change
570
00:37:52,639 --> 00:37:54,556
and because of the long drought,
571
00:37:54,639 --> 00:37:56,680
millions of trees are very weak
572
00:37:56,764 --> 00:38:00,930
and have difficulty defending
themselves against the beetles.
573
00:38:01,014 --> 00:38:05,805
Biochar can definitely be one of the ways
that we address the beetle damage
574
00:38:05,889 --> 00:38:08,431
in the dead and dying trees
of the Sierras.
575
00:38:08,514 --> 00:38:13,514
Biochar is essentially the form
of charcoal that is suitable
576
00:38:13,598 --> 00:38:15,139
for use in agriculture
577
00:38:15,222 --> 00:38:18,680
and in helping to build
more healthy soil.
578
00:38:21,722 --> 00:38:24,805
When you pyrolize woody biomass
particularly,
579
00:38:24,889 --> 00:38:28,972
about half of the carbon
that is in that woody biomass
580
00:38:29,056 --> 00:38:32,764
can be saved,
is a residual charcoal.
581
00:38:32,847 --> 00:38:36,514
And biochar is very much
like coral for the soil
582
00:38:36,598 --> 00:38:39,556
in that it can hold nutrients,
it can hold water.
583
00:38:39,639 --> 00:38:41,722
It's more of an architecture.
584
00:38:41,805 --> 00:38:43,638
It incubates life.
585
00:38:43,721 --> 00:38:46,972
You're saving about half of
the carbon that's in that plant
586
00:38:47,056 --> 00:38:50,431
and then can put it to better
use and sequestering it in soil
587
00:38:50,514 --> 00:38:53,389
for great benefit
to agriculture.
588
00:38:53,473 --> 00:38:56,764
We have all this biomass that
we have to do something with.
589
00:38:56,847 --> 00:38:59,472
They are a fire hazard and,
as you know,
590
00:38:59,555 --> 00:39:03,264
right now we have something
like ten fires in California.
591
00:39:03,348 --> 00:39:08,180
And by producing biochar we can return
some of that material back into the forest
592
00:39:08,263 --> 00:39:11,847
in a safe manner, or we can take some
of that biochar
593
00:39:11,930 --> 00:39:13,972
and take it down into
the Central Valley,
594
00:39:14,056 --> 00:39:16,971
which desperately needs
water savings.
595
00:39:17,055 --> 00:39:19,680
And one of the prime benefits
of biochar
596
00:39:19,764 --> 00:39:23,514
is that it can help
to retain water in soils.
597
00:39:23,598 --> 00:39:28,556
If we put biochar in
just 10% of the world's soil,
598
00:39:28,639 --> 00:39:33,513
we'll actually sequester
29 billion tons of CO2.
599
00:39:33,597 --> 00:39:36,472
29 billion tons.
That's on 10%.
600
00:39:36,555 --> 00:39:39,514
And that's using only--
quote-unquote--
601
00:39:39,598 --> 00:39:43,513
"surplus waste material,"
so that's significant.
602
00:39:45,472 --> 00:39:49,014
And then we have
the carbon offset credits.
603
00:39:49,097 --> 00:39:50,888
And to keep those carbon
credits coming,
604
00:39:50,971 --> 00:39:54,055
we have to employ workers
to do our forest inventories,
605
00:39:54,138 --> 00:39:56,389
to work with the carbon verifiers
606
00:39:56,473 --> 00:39:59,180
to make sure the carbon
that we say is on the property
607
00:39:59,263 --> 00:40:00,721
is on the property,
608
00:40:00,804 --> 00:40:03,138
and then is maintained
into the future.
609
00:40:03,221 --> 00:40:06,264
I'd like to think that we're a model
that others can join in
610
00:40:06,348 --> 00:40:09,055
and do the same thing
that we're doing out here.
611
00:40:09,138 --> 00:40:10,721
This isn't rocket science.
612
00:40:10,804 --> 00:40:15,305
The carbon storage, as we move
into the future, is huge.
613
00:40:15,388 --> 00:40:18,597
And we need more larger,
614
00:40:18,679 --> 00:40:20,930
older forests, intact forests,
615
00:40:21,014 --> 00:40:23,222
that we know will never be developed
616
00:40:23,306 --> 00:40:25,888
and can continue
into perpetuity.
617
00:40:42,513 --> 00:40:44,513
I'm Kate Scow,
and I'm a professor
618
00:40:44,597 --> 00:40:46,347
in Land, Air and Water Resources
619
00:40:46,430 --> 00:40:48,431
at University of California,
Davis.
620
00:40:48,514 --> 00:40:51,472
And I'm a soil microbial ecologist.
621
00:40:51,555 --> 00:40:54,929
So the carbon cycle
on a global scale
622
00:40:55,013 --> 00:40:58,763
involves aquatic systems
and terrestrial systems.
623
00:40:58,846 --> 00:41:02,971
So soil is a very important part of the
terrestrial systems.
624
00:41:05,264 --> 00:41:08,388
Soil actually contains
two to three times
625
00:41:08,472 --> 00:41:10,679
the amount of carbon
that is in the atmosphere.
626
00:41:10,763 --> 00:41:15,513
Soil is the place where primary
productivity is supported.
627
00:41:15,597 --> 00:41:18,679
That means all the vegetation
that grows,
628
00:41:18,763 --> 00:41:22,679
that fixes CO2
through photosynthesis
629
00:41:22,763 --> 00:41:24,138
from the atmosphere,
630
00:41:24,221 --> 00:41:25,555
what miraculous, like,
631
00:41:25,638 --> 00:41:27,347
creating mass here on the ground
632
00:41:27,430 --> 00:41:28,971
out of what? Air?
633
00:41:29,055 --> 00:41:31,347
It's, like, still amazing to me.
634
00:41:31,430 --> 00:41:34,472
That productivity brings
all this carbon in.
635
00:41:34,555 --> 00:41:37,430
The plant fixes the CO2,
it dies,
636
00:41:37,513 --> 00:41:39,721
it falls onto the ground,
637
00:41:39,804 --> 00:41:41,138
and all that plant residue
638
00:41:41,221 --> 00:41:43,804
now enters into
the soil carbon cycle.
639
00:41:43,888 --> 00:41:46,180
It's way bigger than
the atmosphere,
640
00:41:46,263 --> 00:41:49,096
what is residing in soil.
641
00:41:50,513 --> 00:41:54,472
So organic farms
obtain their nutrients
642
00:41:54,555 --> 00:41:56,970
not from synthetic fertilizers.
643
00:41:57,054 --> 00:42:01,597
The fertilizer is in the form
of organic material.
644
00:42:01,679 --> 00:42:04,596
That could be cover crops,
or it could be compost
645
00:42:04,678 --> 00:42:08,888
that's made of food wastes
or yard wastes or animal waste
646
00:42:08,971 --> 00:42:10,638
that you put in the soil.
647
00:42:10,721 --> 00:42:12,970
So in organic systems,
you may be putting
648
00:42:13,054 --> 00:42:17,013
up to eight times as much
carbon into the soil
649
00:42:17,096 --> 00:42:19,846
compared to a conventional system.
650
00:42:19,929 --> 00:42:23,430
So it's like part of it
is really basic.
651
00:42:26,430 --> 00:42:30,554
Climate change
gives us an opportunity
652
00:42:30,637 --> 00:42:35,013
to really behave differently
on this planet.
653
00:42:35,096 --> 00:42:38,055
We see what we can do
at our worst,
654
00:42:38,138 --> 00:42:40,304
and now the question is,
655
00:42:40,387 --> 00:42:46,221
if we were to consciously...
656
00:42:46,305 --> 00:42:50,013
be a part of the healing...
657
00:42:50,096 --> 00:42:53,929
it'll unleash,
I think, our creativity.
658
00:42:56,012 --> 00:42:59,138
You realize, "Oh my gosh,
I have a back yard.
659
00:42:59,221 --> 00:43:03,180
Oh my gosh,
I have a park near me."
660
00:43:05,095 --> 00:43:08,347
If we were to see ourselves
as helpers
661
00:43:08,430 --> 00:43:11,138
who could help the helpers
heal this planet...
662
00:43:13,762 --> 00:43:16,096
that is so much better
than seeing ourselves
663
00:43:16,180 --> 00:43:18,597
as disruptive toddlers
with matches.
664
00:43:18,679 --> 00:43:24,012
You begin to realize that all
of us are somehow connected
665
00:43:24,095 --> 00:43:26,597
to little bits of the solution.
666
00:43:26,679 --> 00:43:30,387
Right now we live and direct
at my mentor's house,
667
00:43:30,471 --> 00:43:33,763
the OG, the organic gardener,
Ron Finley.
668
00:43:33,846 --> 00:43:35,846
I'm more inspired to always
come here
669
00:43:35,929 --> 00:43:37,678
and learn and figure out
different ways
670
00:43:37,762 --> 00:43:40,429
to how I can actually utilize
a small plot of land
671
00:43:40,512 --> 00:43:43,096
to grow the most that I can.
672
00:43:43,180 --> 00:43:46,262
Culinary climate action is
basically what I like to see,
673
00:43:46,346 --> 00:43:50,971
when I'm growing the food and it's basically
taking all that carbon out the atmosphere,
674
00:43:51,055 --> 00:43:52,472
it's pulling it in.
675
00:43:52,555 --> 00:43:54,013
And we also can see the fact
676
00:43:54,095 --> 00:43:56,554
that we can put it back
into the soil.
677
00:43:58,887 --> 00:44:01,888
Now only at the same time
it's creating green jobs,
678
00:44:01,971 --> 00:44:05,512
you know, and also addressing
things like diabetes and obesity
679
00:44:05,596 --> 00:44:07,179
in my community,
where I come from.
680
00:44:07,262 --> 00:44:09,138
You know, there's a lot of plots,
681
00:44:09,221 --> 00:44:10,888
there's a lot of city access,
682
00:44:10,970 --> 00:44:12,803
there's a lot of water
that's available.
683
00:44:12,887 --> 00:44:15,596
This is really just
a beautiful cause and effect.
684
00:44:15,678 --> 00:44:20,596
We're literally pulling out
all the harmful poisons
685
00:44:20,678 --> 00:44:23,471
that we, like, literally just
emit into our atmosphere.
686
00:44:23,554 --> 00:44:27,513
And the best way that you want to transform
that is by growing some food.
687
00:44:27,597 --> 00:44:29,928
Put it on the roof.
Put it in your window sill.
688
00:44:31,387 --> 00:44:33,512
But we feel the heat rising.
689
00:44:33,596 --> 00:44:35,929
You know, being a farmer
is being futuristic.
690
00:44:36,013 --> 00:44:37,554
There is no doomsday mentality.
691
00:44:37,637 --> 00:44:39,346
You have to actually
plant water
692
00:44:39,429 --> 00:44:41,596
and think that you're going
to reap what you sow.
693
00:44:41,678 --> 00:44:43,888
So that's the conversation
that I'd like to see
694
00:44:43,971 --> 00:44:46,512
when we're talking about
transforming the climate.
695
00:44:46,596 --> 00:44:48,012
It's not gonna happen overnight.
696
00:44:48,095 --> 00:44:51,554
But you do have to start now.
Now is the time.
697
00:45:13,179 --> 00:45:14,928
My name is Bren Smith.
698
00:45:15,012 --> 00:45:17,262
I'm the owner
of Thimble Island Ocean Farm.
699
00:45:17,346 --> 00:45:21,928
And we're here in the Thimble
Islands in Long Island Sound.
700
00:45:22,012 --> 00:45:25,054
And I was, I'm born and raised
in Newfoundland, Canada,
701
00:45:25,137 --> 00:45:27,887
high school dropout, and have
fished all over the globe.
702
00:45:27,970 --> 00:45:30,387
I fished in Gloucester
up in Newfoundland,
703
00:45:30,471 --> 00:45:32,887
and then I was in the Bering Sea
for a bunch of years.
704
00:45:32,970 --> 00:45:36,304
And, you know, that was the height of
industrialized fishing.
705
00:45:36,387 --> 00:45:39,220
We were tearing up entire
eco-systems with our trawls,
706
00:45:39,304 --> 00:45:42,220
chasing fewer and fewer fish
further and further out to sea.
707
00:45:42,304 --> 00:45:44,178
So it was completely unsustainable.
708
00:45:44,261 --> 00:45:45,928
In fact, a lot of the fish
I was catching
709
00:45:46,012 --> 00:45:49,262
was going to McDonald's
for their Fishwich sandwich.
710
00:45:51,471 --> 00:45:53,386
It really caused a wake-up call
711
00:45:53,470 --> 00:45:55,554
for a lot of folks
in my generation.
712
00:45:55,678 --> 00:45:57,637
I was actually out
in the Bering Sea,
713
00:45:57,720 --> 00:45:59,346
and the cod stocks crashed.
714
00:45:59,429 --> 00:46:02,094
And, you know, thousands
of people thrown out of work,
715
00:46:02,178 --> 00:46:04,429
canneries shuttered,
and it really taught me
716
00:46:04,512 --> 00:46:08,179
that you can build up an economy and
a culture over hundreds of years
717
00:46:08,262 --> 00:46:10,178
and if you don't protect
the resources,
718
00:46:10,261 --> 00:46:13,387
eco-system collapse can wipe it
out in a matter of years.
719
00:46:15,887 --> 00:46:18,386
And that's when
we really begin to realize
720
00:46:18,470 --> 00:46:22,262
that issues like overfishing,
like climate change,
721
00:46:22,346 --> 00:46:24,012
that they're not
environmental issues
722
00:46:24,095 --> 00:46:25,927
for a lot of us
that work on the ocean,
723
00:46:26,011 --> 00:46:27,595
they're economic issues. I mean,
724
00:46:27,677 --> 00:46:30,179
there's gonna be no food,
no jobs, on a dead planet.
725
00:46:32,596 --> 00:46:34,470
When I realized
this wasn't sustainable,
726
00:46:34,553 --> 00:46:37,471
I went on this search
for sustainability.
727
00:46:37,554 --> 00:46:40,179
I remade myself
as an oysterman.
728
00:46:40,262 --> 00:46:43,136
And what oysters taught me
was that Mother Nature
729
00:46:43,219 --> 00:46:45,844
created these technologies
millions of years ago
730
00:46:45,927 --> 00:46:47,554
designed to mitigate our harm.
731
00:46:47,637 --> 00:46:49,637
We don't need advanced technologies.
732
00:46:49,720 --> 00:46:52,470
Mother Nature has seaweeds
and shellfish
733
00:46:52,553 --> 00:46:55,762
which sequester five times more
carbon than land-based plants,
734
00:46:55,845 --> 00:46:59,137
filter 50 gallons of water
a day per oyster
735
00:46:59,220 --> 00:47:00,802
pulling nitrogen out of our system.
736
00:47:00,886 --> 00:47:03,303
I mean, my job as
a steward of the ocean
737
00:47:03,386 --> 00:47:06,803
is to take Mother Nature's
technologies and grow them.
738
00:47:06,887 --> 00:47:08,886
And it's pretty simple.
739
00:47:08,969 --> 00:47:13,637
So the beautiful thing about if
you grow just restorative species,
740
00:47:13,720 --> 00:47:15,512
is there's zero inputs.
741
00:47:15,596 --> 00:47:18,011
We don't need fresh water,
we don't need animal feed,
742
00:47:18,094 --> 00:47:20,511
we don't need fertilizer
and we don't need land,
743
00:47:20,595 --> 00:47:23,845
making it hands down the most
sustainable form of food production
744
00:47:23,928 --> 00:47:26,053
on the planet.
745
00:47:26,136 --> 00:47:29,470
So kelp is
this beautiful seaweed.
746
00:47:29,553 --> 00:47:32,471
It's like the gateway drug
to a new cuisine.
747
00:47:32,554 --> 00:47:34,719
It's one of the fastest-growing
plants on earth.
748
00:47:34,802 --> 00:47:38,053
It soaks up five times more
carbon than land-based plants.
749
00:47:38,136 --> 00:47:39,887
It's called the Sequoia of the Sea.
750
00:47:39,970 --> 00:47:41,677
But it's just the beginning.
751
00:47:41,761 --> 00:47:43,345
I mean, we're starting with kelp,
752
00:47:43,428 --> 00:47:47,178
but there are 10,000 edible
plants in the ocean.
753
00:47:47,261 --> 00:47:50,261
Part of the plant we can turn
into kelp noodles,
754
00:47:50,345 --> 00:47:54,844
but then this is just biofuel
we turn into fertilizer
755
00:47:54,927 --> 00:47:56,970
and we can turn
into animal feed.
756
00:47:57,054 --> 00:48:00,053
If you provide a seaweed diet
to cows,
757
00:48:00,136 --> 00:48:03,303
you get a 90% reduction
in methane output.
758
00:48:03,386 --> 00:48:05,387
It's stunning.
And cows have been eating--
759
00:48:05,471 --> 00:48:08,677
cows, sheep, goats, have been eating
kelp for hundreds of years.
760
00:48:08,761 --> 00:48:11,053
Hebrides Islands, Maine,
all sorts of places.
761
00:48:11,136 --> 00:48:12,553
You know, the volume's stunning.
762
00:48:12,636 --> 00:48:16,053
We can do 10 to 20 tons
of kelp per acre,
763
00:48:16,136 --> 00:48:18,011
150,000 shellfish.
764
00:48:18,094 --> 00:48:19,470
And you scale this up,
765
00:48:19,553 --> 00:48:21,219
if you were to take
a network of our farms
766
00:48:21,303 --> 00:48:23,054
totaling the size
of Washington State,
767
00:48:23,137 --> 00:48:25,094
technically you could
feed the world.
768
00:48:25,178 --> 00:48:28,094
If you took five percent
of U.S. territorial waters
769
00:48:28,178 --> 00:48:30,011
and farmed in our style,
770
00:48:30,094 --> 00:48:31,887
you could create
50 million direct jobs
771
00:48:31,970 --> 00:48:36,303
and sequester the equivalent
carbon of 20 million cars.
772
00:48:38,553 --> 00:48:41,677
Our farms also help mitigate
acidification.
773
00:48:41,761 --> 00:48:44,802
The kelp creates something
called a Halo Effect
774
00:48:44,886 --> 00:48:48,428
which reduces the acidity
in the oceans,
775
00:48:48,511 --> 00:48:51,053
which then allow our oysters
and other shellfish
776
00:48:51,136 --> 00:48:53,094
to grow thicker shells
777
00:48:53,178 --> 00:48:57,761
and not be as susceptible
to acidification.
778
00:48:57,844 --> 00:49:00,553
So, I mean, climate change
was supposed to be
779
00:49:00,636 --> 00:49:04,094
this 100-year
sort of slow lobster boil.
780
00:49:04,178 --> 00:49:05,719
And instead it's here and now.
781
00:49:05,801 --> 00:49:07,428
Luckily, as fishermen,
782
00:49:07,511 --> 00:49:09,802
we can transition to something
that keeps that
783
00:49:09,886 --> 00:49:12,011
and have the pride of helping
feed my country,
784
00:49:12,094 --> 00:49:13,261
and that's just so exciting.
785
00:49:13,345 --> 00:49:15,136
I can be part of, you know,
786
00:49:15,219 --> 00:49:16,595
the army that's going to help,
787
00:49:16,677 --> 00:49:18,636
hopefully, save the planet.
788
00:49:30,969 --> 00:49:34,136
If we put 10 units of CO2
in the atmosphere,
789
00:49:34,219 --> 00:49:36,636
ten very large units of CO2
in the atmosphere,
790
00:49:36,719 --> 00:49:38,844
about five stay in the atmosphere
791
00:49:38,927 --> 00:49:40,843
and about two and a half
go into plants
792
00:49:40,926 --> 00:49:43,636
and about two and a half
goes into the ocean.
793
00:49:43,719 --> 00:49:47,219
So you've got an acidic ocean.
So how do you deal with that?
794
00:49:47,303 --> 00:49:50,886
Nature handles this problem
by making more shells,
795
00:49:50,969 --> 00:49:54,677
which is the marine snow idea,
796
00:49:54,761 --> 00:49:56,843
that little beasties
grow in the water,
797
00:49:56,926 --> 00:50:00,219
they make calcium carbonate
shells, so shells fall.
798
00:50:00,303 --> 00:50:03,511
The problem with that is,
the planet loves to operate
799
00:50:03,595 --> 00:50:06,177
on time scales
of millions of years.
800
00:50:06,260 --> 00:50:08,677
And we don't.
801
00:50:08,761 --> 00:50:13,094
So, question becomes, can you
speed that process up?
802
00:50:17,802 --> 00:50:21,303
We have to investigate
all our options.
803
00:50:21,386 --> 00:50:23,635
There are more experimental
hypotheses
804
00:50:23,718 --> 00:50:25,886
that still need to be tested.
805
00:50:25,969 --> 00:50:32,218
One solution may lie in a microscopic community
of life called marine snow.
806
00:50:34,636 --> 00:50:37,719
So, fundamentally,
what do we need?
807
00:50:37,802 --> 00:50:41,344
Well, we need this planet
as it was,
808
00:50:41,427 --> 00:50:45,677
we have to bring it in the state that
it was 200 years ago.
809
00:50:45,761 --> 00:50:49,010
Higher concentrations
of carbon dioxide,
810
00:50:49,093 --> 00:50:51,761
they increase acidity
of the ocean.
811
00:50:51,844 --> 00:50:54,553
The oceans are losing
their ability
812
00:50:54,636 --> 00:50:57,385
to capture carbon
from the atmosphere.
813
00:50:57,469 --> 00:51:00,219
And we have to do something about it.
814
00:51:00,303 --> 00:51:03,345
We have to help these systems
815
00:51:03,428 --> 00:51:07,594
which cycle carbon
between the atmosphere,
816
00:51:07,676 --> 00:51:10,511
between the plants on the land,
817
00:51:10,595 --> 00:51:13,260
and between the oceans.
818
00:51:13,344 --> 00:51:15,635
And with marine snow,
819
00:51:15,718 --> 00:51:19,719
it just needs a little help
from us.
820
00:51:19,802 --> 00:51:23,718
The main products will be
removal of carbon dioxide
821
00:51:23,801 --> 00:51:26,761
and the production of oxygen.
822
00:51:26,844 --> 00:51:28,470
What we can do is
823
00:51:28,553 --> 00:51:31,676
insert into the ocean
very small,
824
00:51:31,760 --> 00:51:35,636
minute amounts of iron,
825
00:51:35,719 --> 00:51:37,428
but very, very little,
826
00:51:37,510 --> 00:51:39,260
so it doesn't have
anything to do
827
00:51:39,344 --> 00:51:41,926
with that term "fertilization."
828
00:51:42,010 --> 00:51:44,927
To give you a measure,
we need altogether
829
00:51:45,011 --> 00:51:48,635
about 6 kilograms of iron
for initiating this process
830
00:51:48,718 --> 00:51:52,886
on 100,000 square kilometers
of the southern oceans.
831
00:51:52,969 --> 00:51:56,510
The cells form organic matrix,
832
00:51:56,594 --> 00:51:58,469
which is the foundation
833
00:51:58,552 --> 00:52:01,844
for the formation
of the marine snow.
834
00:52:01,927 --> 00:52:05,676
It is then,
when the matrix appears,
835
00:52:05,760 --> 00:52:09,010
it becomes very attractive
for cyanobacteria
836
00:52:09,093 --> 00:52:11,302
and heterotrophic bacteria,
837
00:52:11,385 --> 00:52:15,510
which colonize these particles,
and then actively grow.
838
00:52:15,594 --> 00:52:18,927
And then we just
let them do their job,
839
00:52:19,011 --> 00:52:22,344
because they can stay suspended
840
00:52:22,427 --> 00:52:25,177
for a very long period of time.
841
00:52:25,260 --> 00:52:28,135
We tracked these
marine snow particles
842
00:52:28,218 --> 00:52:30,635
for more than four months...
843
00:52:30,718 --> 00:52:35,260
so they can float around
and sequester organic matter,
844
00:52:35,344 --> 00:52:36,968
and when they become heavy,
845
00:52:37,052 --> 00:52:40,510
they simply sink down
to the sea floor.
846
00:52:43,135 --> 00:52:45,926
The speed of this change,
847
00:52:46,010 --> 00:52:49,135
and increase in the concentrations
and temperature--
848
00:52:49,218 --> 00:52:51,093
we must act.
849
00:52:51,177 --> 00:52:52,427
And we can.
850
00:52:52,510 --> 00:52:56,594
I'm 100% positive
that we can achieve
851
00:52:56,676 --> 00:53:01,469
um...reorganization
of human activities
852
00:53:01,552 --> 00:53:05,427
to work together with nature,
and not against it.
853
00:53:14,718 --> 00:53:18,675
Science has long proven
we have existing technologies
854
00:53:18,759 --> 00:53:22,469
that work, and they are
already being implemented.
855
00:53:22,552 --> 00:53:26,385
It's just become a matter
of political will and scale.
856
00:53:26,469 --> 00:53:31,260
We need a multitude of solutions
moving forward simultaneously.
857
00:53:31,344 --> 00:53:34,010
In order to solve this crisis,
858
00:53:34,093 --> 00:53:39,302
it is critical we move
to 100% renewable energy now.
859
00:53:39,385 --> 00:53:41,385
So, the top five solutions,
860
00:53:41,469 --> 00:53:45,634
number two was onshore wind,
and that wasn't a surprise.
861
00:53:53,301 --> 00:53:57,260
Onshore wind, though,
being much greater than solar,
862
00:53:57,344 --> 00:53:59,760
was a surprise to us.
863
00:54:03,968 --> 00:54:07,510
Solar was number eight in ten,
actually.
864
00:54:11,967 --> 00:54:15,218
The sun is the largest resource
we have.
865
00:54:15,302 --> 00:54:17,925
All the other resources pale
compared to the sun.
866
00:54:18,009 --> 00:54:19,759
We have known that
for a long time,
867
00:54:19,842 --> 00:54:23,093
we just never understood how to
harvest it in an economic way.
868
00:54:23,177 --> 00:54:25,302
That's what's different now.
869
00:54:25,385 --> 00:54:28,675
Solar PV is in a stage where we're already
lower than fossil fuel.
870
00:54:28,759 --> 00:54:30,968
Well, solar has come a long way.
871
00:54:31,052 --> 00:54:34,260
Carter in the '80s already installed solar
in the White House.
872
00:54:34,344 --> 00:54:36,426
Reagan tore it down later on.
873
00:54:36,509 --> 00:54:39,135
And only in 2001,
874
00:54:39,218 --> 00:54:42,760
when Germany started to deploy
solar on a large scale,
875
00:54:42,842 --> 00:54:46,426
we have been getting the benefit
of economy of scale.
876
00:54:46,509 --> 00:54:49,469
Eventually we will be able to power
877
00:54:49,552 --> 00:54:53,259
the entire electrical grids
with solar and wind,
878
00:54:53,343 --> 00:54:57,135
and all we need is wind and storage,
and solar and storage.
879
00:54:59,635 --> 00:55:03,593
So, if you want to power the entire
United States with photovoltaic,
880
00:55:03,675 --> 00:55:07,052
we would need about
30,000 square miles in area.
881
00:55:07,135 --> 00:55:09,134
That would give us
enough to power
882
00:55:09,217 --> 00:55:12,717
all the power grids in every
state of the United States.
883
00:55:15,885 --> 00:55:20,800
Mount Signal is a project that powers
about 70,000 homes in San Diego.
884
00:55:20,884 --> 00:55:25,426
The second phase, the power is going
to be wheeled to Southern California.
885
00:55:27,551 --> 00:55:31,217
The price of electricity that
we produce at Mount Signal
886
00:55:31,301 --> 00:55:33,800
is already lower
than fossil fuels.
887
00:55:33,884 --> 00:55:38,051
It's also a price that delivers
fuel price certainty to the utility.
888
00:55:39,925 --> 00:55:43,176
The price is flat
over the next 25 years,
889
00:55:43,259 --> 00:55:49,052
not something that you get from
any other fossil fuel energies.
890
00:55:49,135 --> 00:55:52,634
We have integrated so much
solar in California already.
891
00:55:52,717 --> 00:55:55,675
Ten years ago, people would've said,
"No, that's not really possible."
892
00:55:55,759 --> 00:55:58,925
Well, here we are,
solar is covering already
893
00:55:59,009 --> 00:56:01,301
up to 25% of California.
894
00:56:01,384 --> 00:56:04,551
The rate payer had no
material increase in pricing,
895
00:56:04,634 --> 00:56:07,010
and we're still alive,
it all works.
896
00:56:07,092 --> 00:56:10,759
And we have been able to reduce
carbon on the way there.
897
00:56:15,717 --> 00:56:18,176
Over the last years we saw now
898
00:56:18,259 --> 00:56:21,092
utilities volunteering
to buy solar.
899
00:56:21,176 --> 00:56:24,051
We see this mindset shifting.
900
00:56:24,134 --> 00:56:27,551
We still under-appreciate
the value that PV brings.
901
00:56:27,634 --> 00:56:31,259
People do not comprehend
that in five years,
902
00:56:31,343 --> 00:56:33,468
we will have PV at much lower price.
903
00:56:33,551 --> 00:56:36,009
We will be able
to dispatch it at night,
904
00:56:36,092 --> 00:56:38,634
and you combine that with wind,
you get this paradigm
905
00:56:38,717 --> 00:56:42,217
where we are truly living in a hundred
percent renewable environment.
906
00:56:42,301 --> 00:56:44,384
And this is feasible.
907
00:56:44,468 --> 00:56:47,426
We don't need
any new invention for that,
908
00:56:47,509 --> 00:56:49,092
we know all the technology.
909
00:56:49,176 --> 00:56:53,384
We just need to make sure that
the people responsible
910
00:56:53,468 --> 00:56:57,674
for the planning of resources,
for the infrastructure planning,
911
00:56:57,758 --> 00:57:01,343
understand that this
is a different technology,
912
00:57:01,426 --> 00:57:04,384
and it will get cheaper over time.
913
00:57:08,675 --> 00:57:10,301
Coal is coming back.
914
00:57:10,384 --> 00:57:11,884
- Clean coal is coming back.
915
00:57:11,967 --> 00:57:13,967
A hundred percent.
916
00:57:14,051 --> 00:57:18,675
My administration is putting
an end to the war on coal.
917
00:57:18,759 --> 00:57:22,468
Gonna have clean coal,
really clean coal.
918
00:57:51,551 --> 00:57:53,468
It's difficult enough,
sometimes,
919
00:57:53,551 --> 00:57:55,259
to communicate science
to the public.
920
00:57:55,343 --> 00:57:58,133
Now, you take that challenge,
921
00:57:58,216 --> 00:58:00,551
and you add to it
922
00:58:00,634 --> 00:58:05,592
a concerted effort
by fossil fuel interests
923
00:58:05,674 --> 00:58:07,467
and the front groups
that they fund
924
00:58:07,550 --> 00:58:10,343
to pollute the discourse
over climate change,
925
00:58:10,426 --> 00:58:13,799
to confuse the public,
to confuse policymakers.
926
00:58:13,883 --> 00:58:16,258
We need to transform
our energy sector,
927
00:58:16,342 --> 00:58:18,217
move away from
fossil fuel energy,
928
00:58:18,301 --> 00:58:19,717
towards renewable energy.
929
00:58:19,800 --> 00:58:21,800
Well, that's rather inconvenient
930
00:58:21,884 --> 00:58:23,924
for the powerful
fossil fuel interests
931
00:58:24,008 --> 00:58:27,176
who have many millions
of dollars invested
932
00:58:27,259 --> 00:58:29,925
in our continued addiction
to fossil fuels.
933
00:58:30,009 --> 00:58:31,674
And they've fought
tooth and nail
934
00:58:31,758 --> 00:58:33,383
to maintain that addiction,
935
00:58:33,467 --> 00:58:35,301
in part by attacking the science
936
00:58:35,384 --> 00:58:39,425
linking climate change
to that behavior,
937
00:58:39,508 --> 00:58:41,924
the burning of fossil fuels.
938
00:58:45,925 --> 00:58:47,799
A question that
we get asked a lot is,
939
00:58:47,883 --> 00:58:51,091
how do we know that
the CO2 rise in the atmosphere
940
00:58:51,175 --> 00:58:52,758
is because of human activity.
941
00:58:52,842 --> 00:58:55,716
And the answer is that
we leave fingerprints
942
00:58:55,799 --> 00:58:58,592
all over the atmosphere.
943
00:58:58,674 --> 00:59:02,384
And one of the fingerprints
that we leave in the atmosphere
944
00:59:02,468 --> 00:59:06,674
is via what we call Carbon-14,
or radioactive carbon.
945
00:59:06,758 --> 00:59:09,133
So when we burn coal, oil,
and natural gas,
946
00:59:09,216 --> 00:59:11,593
we leave an imprint
on the atmosphere
947
00:59:11,675 --> 00:59:16,175
of what we call negative
Carbon-14, or less Carbon-14.
948
00:59:16,258 --> 00:59:18,383
Because fossil fuels are so old,
949
00:59:18,467 --> 00:59:20,966
there's no Carbon-14 left,
it's all decayed away.
950
00:59:21,050 --> 00:59:23,716
We can actually measure,
very accurately,
951
00:59:23,799 --> 00:59:26,008
how much fossil fuels we burn
952
00:59:26,091 --> 00:59:28,509
by measuring C-14
in the atmosphere.
953
00:59:28,593 --> 00:59:33,758
It is nature's verification
system that we have.
954
00:59:36,967 --> 00:59:39,008
They've persuaded enough people
955
00:59:39,091 --> 00:59:41,258
and sowed enough doubt
956
00:59:41,342 --> 00:59:45,258
that it's making it more
difficult than in the past
957
00:59:45,343 --> 00:59:47,841
to actually get anything done
about climate change,
958
00:59:47,924 --> 00:59:49,799
and that's really depressing.
959
00:59:49,883 --> 00:59:51,841
And the fact is that the agenda
960
00:59:51,924 --> 00:59:54,176
that many of these
fossil fuel corporations,
961
00:59:54,259 --> 00:59:57,883
and those who are running them
are engaged in, is malicious
962
00:59:57,966 --> 00:59:59,467
in the danger it's creating
963
00:59:59,550 --> 01:00:01,550
and the havoc that it is
wreaking on our planet.
964
01:00:01,633 --> 01:00:03,425
So we've got a bunch of people
965
01:00:03,508 --> 01:00:08,091
who are literally profiting
off the death of life on Earth.
966
01:00:08,175 --> 01:00:11,133
I think that some climate denial,
967
01:00:11,216 --> 01:00:13,342
particularly the well-funded
climate denial,
968
01:00:13,425 --> 01:00:16,133
that is being done by people
who know better,
969
01:00:16,216 --> 01:00:18,550
rises to the level of a crime
against humanity
970
01:00:18,633 --> 01:00:21,175
that probably should be
prosecuted in the Hague.
971
01:00:29,342 --> 01:00:33,425
While climate deniers have
succeeded in delaying action,
972
01:00:33,508 --> 01:00:36,840
a much more ominous problem
has emerged.
973
01:00:36,923 --> 01:00:39,633
Very recently,
scientists have recorded
974
01:00:39,716 --> 01:00:43,758
increasing levels of
methane gas in the atmosphere.
975
01:00:43,841 --> 01:00:47,175
Methane, a powerful greenhouse gas,
976
01:00:47,258 --> 01:00:51,508
has the potential to increase
temperatures even further.
977
01:00:51,592 --> 01:00:53,508
Increased methane is a sign
978
01:00:53,591 --> 01:00:56,674
that we are reaching a critical
tipping point.
979
01:00:56,758 --> 01:00:58,674
But where is it coming from?
980
01:00:58,758 --> 01:01:03,007
And how much will it accelerate
climate disruption?
981
01:01:03,090 --> 01:01:05,758
Scientists are racing to find out.
982
01:01:11,757 --> 01:01:13,966
So, we are in front of
983
01:01:14,050 --> 01:01:16,300
the University of Wyoming
Mobile Laboratory.
984
01:01:16,383 --> 01:01:18,923
We have different
instruments inside
985
01:01:19,007 --> 01:01:22,425
that measure what's in the air
that we are breathing right now.
986
01:01:22,508 --> 01:01:24,342
It's doing that in real time.
987
01:01:24,425 --> 01:01:25,924
And we are able, like that,
988
01:01:26,008 --> 01:01:28,382
to chase emission sources
and plumes,
989
01:01:28,466 --> 01:01:32,175
and understand where sources of pollutions
are located,
990
01:01:32,258 --> 01:01:36,090
what activities are going on that lead
to enhanced methane.
991
01:01:38,673 --> 01:01:40,924
Inside of our lab,
we have a couple instruments.
992
01:01:41,008 --> 01:01:44,840
We have a proton-transfer-reaction
time-of-flight mass spec
993
01:01:44,923 --> 01:01:48,758
to measure volatile organics
like benzene, toluene.
994
01:01:48,841 --> 01:01:51,841
And then we also have
a Picarro cavity ring-down
995
01:01:51,924 --> 01:01:54,174
to measure methane concentrations.
996
01:01:54,257 --> 01:01:57,883
We can see data from these
instruments in real time
997
01:01:57,966 --> 01:02:01,382
due to an inlet we have
up on our mast above the van,
998
01:02:01,466 --> 01:02:04,715
which pulls air in and feeds
into our instruments.
999
01:02:04,798 --> 01:02:08,924
So, we found with
aerial and road mapping
1000
01:02:09,008 --> 01:02:12,215
that we have more sources
of methane in areas
1001
01:02:12,299 --> 01:02:14,924
where we extract the gas
than we expected.
1002
01:02:15,008 --> 01:02:18,466
And to really pinpoint where
there are leaks of methane,
1003
01:02:18,549 --> 01:02:20,715
you need to be very close
to the sources.
1004
01:02:20,798 --> 01:02:23,758
And the mobile lab
gives us the flexibility
1005
01:02:23,841 --> 01:02:27,882
to pinpoint where we see
the largest leaks.
1006
01:02:27,965 --> 01:02:31,632
The company has drilled
brand-new megapad,
1007
01:02:31,716 --> 01:02:36,049
22 wells in the middle
of renewed urban development
1008
01:02:36,132 --> 01:02:37,757
in western Greeley.
1009
01:02:37,840 --> 01:02:40,049
This is a site
that had a lot of contention,
1010
01:02:40,132 --> 01:02:42,883
given its size
and its location.
1011
01:02:46,549 --> 01:02:49,090
So the local community,
from what I've heard,
1012
01:02:49,174 --> 01:02:51,591
is not really kept up to breadth
1013
01:02:51,673 --> 01:02:53,382
on what's going on
at the site.
1014
01:02:53,466 --> 01:02:55,840
There's a huge sound wall
around the operation,
1015
01:02:55,923 --> 01:02:59,592
and the state is not really
maybe doing its best
1016
01:02:59,674 --> 01:03:01,965
at facilitating
the communication.
1017
01:03:02,049 --> 01:03:04,591
We saw operations going on
with a lot of flaring.
1018
01:03:04,673 --> 01:03:06,507
It seems very large volume of gas.
1019
01:03:06,591 --> 01:03:08,965
The yellow color of the flame
1020
01:03:09,049 --> 01:03:11,923
tells you it's not
complete combustion.
1021
01:03:12,007 --> 01:03:13,673
So, we are going to continue
1022
01:03:13,757 --> 01:03:15,883
doing those drives to
understand those sources,
1023
01:03:15,966 --> 01:03:20,549
but also to track what the local
population may be exposed to.
1024
01:03:20,632 --> 01:03:23,090
So some oil-
and gas-producing regions
1025
01:03:23,174 --> 01:03:25,965
have such a large
concentration of methane
1026
01:03:26,049 --> 01:03:29,299
in the atmosphere above them
that you can see it from space,
1027
01:03:29,382 --> 01:03:32,798
and that's something that was
described a few years back
1028
01:03:32,882 --> 01:03:34,715
for the Four Corners region,
1029
01:03:34,798 --> 01:03:37,965
and that's really the key
for us to be like detectives
1030
01:03:38,049 --> 01:03:42,050
and map where we see the
largest sources of emissions.
1031
01:03:53,965 --> 01:03:56,965
So in 2014,
1032
01:03:57,049 --> 01:04:00,507
NASA scientists in cooperation
with NOAA,
1033
01:04:00,591 --> 01:04:03,757
University of Michigan,
and other scientists,
1034
01:04:03,840 --> 01:04:06,965
identified a methane hotspot
the size of Delaware
1035
01:04:07,049 --> 01:04:08,757
in the Four Corners region.
1036
01:04:08,840 --> 01:04:10,257
That methane hotspot
1037
01:04:10,341 --> 01:04:12,673
is the largest accumulation
of methane gases
1038
01:04:12,757 --> 01:04:14,840
in the United States.
1039
01:04:14,923 --> 01:04:18,549
This ranch,
this spot that we're on,
1040
01:04:18,632 --> 01:04:20,882
is approximately ground zero.
1041
01:04:20,965 --> 01:04:23,507
If you were able
to identify a middle
1042
01:04:23,591 --> 01:04:26,049
for that Delaware-shaped cloud,
1043
01:04:26,132 --> 01:04:29,007
it might very well be right here
where we're standing.
1044
01:04:29,090 --> 01:04:31,174
And it's closely identified
1045
01:04:31,257 --> 01:04:33,548
the cause of that methane hotspot
1046
01:04:33,631 --> 01:04:38,049
to be predominantly
the emissions from drilling,
1047
01:04:38,132 --> 01:04:39,507
such as this site,
1048
01:04:39,591 --> 01:04:43,132
as well as coal and other
fossil fuels.
1049
01:04:45,965 --> 01:04:48,549
So the methane hotspot
is identified
1050
01:04:48,632 --> 01:04:50,756
basically because
of the technology
1051
01:04:50,839 --> 01:04:52,632
that NOAA and NASA had
1052
01:04:52,715 --> 01:04:55,424
following the advent
of the FLIR cameras,
1053
01:04:55,507 --> 01:04:57,257
which are the infrared cameras
1054
01:04:57,341 --> 01:05:00,882
that let us identify the leaks
and vents and flares
1055
01:05:00,965 --> 01:05:04,424
that cause the methane hotspot
to accumulate.
1056
01:05:04,507 --> 01:05:07,631
You have to think of it
in its full sense,
1057
01:05:07,714 --> 01:05:10,632
and that is 60 years and more
1058
01:05:10,715 --> 01:05:14,341
of leaking, venting, flaring,
1059
01:05:14,424 --> 01:05:17,298
and careless practices
here in the San Juan basin,
1060
01:05:17,381 --> 01:05:21,215
over a million acres,
in total 30,000 wells,
1061
01:05:21,299 --> 01:05:23,797
that have caused
that methane hotspot
1062
01:05:23,881 --> 01:05:25,881
to finally accumulate
1063
01:05:25,964 --> 01:05:28,382
and stand as evidence
1064
01:05:28,466 --> 01:05:31,341
of what natural gas drilling
1065
01:05:31,424 --> 01:05:33,590
ultimately results in.
1066
01:05:33,672 --> 01:05:35,423
People lose sight of the fact
1067
01:05:35,506 --> 01:05:38,757
that the conventional wells
created the methane hotspot,
1068
01:05:38,840 --> 01:05:42,465
and that they are
a daily culprit.
1069
01:05:47,007 --> 01:05:50,590
So, this is a conventional
natural gas well.
1070
01:05:50,672 --> 01:05:53,798
This is very typical equipment
throughout the San Juan basin
1071
01:05:53,882 --> 01:05:55,923
and many gas fields
across America.
1072
01:05:56,007 --> 01:05:58,298
This one is leaking pretty badly
1073
01:05:58,381 --> 01:06:00,922
from some of the standard
equipment that's on it.
1074
01:06:01,006 --> 01:06:03,174
This just requires, honestly,
1075
01:06:03,257 --> 01:06:07,256
a crescent wrench,
a little bit of Teflon tape--
1076
01:06:07,340 --> 01:06:10,048
some attention
will fix this leak.
1077
01:06:10,131 --> 01:06:11,798
If I had a single wish,
1078
01:06:11,882 --> 01:06:17,298
my wish would be to pull
an investor in oil and gas here
1079
01:06:17,381 --> 01:06:20,840
and stand them where I'm standing,
let them see that leak.
1080
01:06:20,923 --> 01:06:24,672
Let them see that times 18,000
in the San Juan basin,
1081
01:06:24,756 --> 01:06:28,048
and get them to stop obstructing
a federal rule
1082
01:06:28,132 --> 01:06:30,507
that stays in place
to protect my family,
1083
01:06:30,590 --> 01:06:33,006
to protect taxpayers
across New Mexico,
1084
01:06:33,089 --> 01:06:36,672
and provide federal
fair and equal protection
1085
01:06:36,756 --> 01:06:38,632
across the western states.
1086
01:06:38,715 --> 01:06:40,881
Let's get those guys
out of the boardroom,
1087
01:06:40,964 --> 01:06:42,672
right here on
this well location,
1088
01:06:42,756 --> 01:06:45,715
let 'em look at that leak
that can be easily fixed.
1089
01:06:45,798 --> 01:06:50,797
And when I found out that
the EPA administrator, Scott Pruitt,
1090
01:06:50,881 --> 01:06:54,131
knew that the data had come in
1091
01:06:54,214 --> 01:06:58,256
that methane leaks and the chemicals
that come with them
1092
01:06:58,340 --> 01:07:02,381
harm children to a greater
degree than they did to me,
1093
01:07:02,465 --> 01:07:06,214
I was just outraged
that he would try again
1094
01:07:06,298 --> 01:07:08,922
to roll back the federal
protections for us.
1095
01:07:09,006 --> 01:07:12,007
You know, if someone
came onto my ranch
1096
01:07:12,090 --> 01:07:15,631
with the stated objective
of harming my children,
1097
01:07:15,714 --> 01:07:18,256
it would be over my dead body.
1098
01:07:31,881 --> 01:07:34,340
250 million years ago,
1099
01:07:34,423 --> 01:07:36,256
sudden releases of methane
1100
01:07:36,340 --> 01:07:38,756
produced kind of a secondary effect
1101
01:07:38,839 --> 01:07:42,672
that finished off large chunks
of life on Earth.
1102
01:07:42,756 --> 01:07:44,672
And one of the debates right now
1103
01:07:44,756 --> 01:07:46,922
is whether the methane
that is buried in the Arctic,
1104
01:07:47,006 --> 01:07:49,214
whether the methane that is,
you know, in the permafrost,
1105
01:07:49,298 --> 01:07:50,881
in the seas all over the world,
1106
01:07:50,964 --> 01:07:54,548
how rapidly that will be mobilized,
1107
01:07:54,631 --> 01:07:57,298
and how destructive
that mobilization will be.
1108
01:07:59,089 --> 01:08:01,381
The release of this ancient methane
1109
01:08:01,465 --> 01:08:05,173
may lead to exponentially
more warming.
1110
01:08:05,256 --> 01:08:08,839
Will this methane create
an apocalyptic scenario?
1111
01:08:08,922 --> 01:08:13,465
This is a question scientists
are desperately trying to answer.
1112
01:08:13,548 --> 01:08:15,631
I'm the director of the Center
1113
01:08:15,714 --> 01:08:18,922
for Gas Hydrate, Environment,
and Climate.
1114
01:08:19,006 --> 01:08:22,298
Here we have a team
of 50 to 60 scientists
1115
01:08:22,381 --> 01:08:25,131
working on understanding
the impact of methane
1116
01:08:25,214 --> 01:08:27,173
on the global climate system.
1117
01:08:27,256 --> 01:08:31,672
This methane is stored
beneath the Arctic Ocean floor
1118
01:08:31,756 --> 01:08:34,465
in huge reservoirs,
1119
01:08:34,548 --> 01:08:36,839
at locations we sometimes know,
1120
01:08:36,922 --> 01:08:39,255
but we often do not know
very much about it.
1121
01:08:39,339 --> 01:08:42,672
So, we are applying here
geophysical methods
1122
01:08:42,756 --> 01:08:46,589
to quantify the methane hydrate
reservoirs,
1123
01:08:46,671 --> 01:08:48,590
and also to see how stable
1124
01:08:48,672 --> 01:08:52,256
those methane hydrates are
today, but also in the future.
1125
01:08:54,297 --> 01:08:58,423
Methane is one of the most
aggressive greenhouse gases.
1126
01:08:58,506 --> 01:09:01,881
Methane has, fortunately,
a shorter lifetime.
1127
01:09:01,964 --> 01:09:07,756
The Earth has a natural system
for regulating input of methane
1128
01:09:07,839 --> 01:09:10,921
from the ocean into the atmosphere.
1129
01:09:11,005 --> 01:09:13,464
And this system
is working quite efficiently.
1130
01:09:13,547 --> 01:09:18,006
But this system is also changing, because
the ocean current system is changing,
1131
01:09:18,089 --> 01:09:20,130
the ocean temperature is changing,
1132
01:09:20,213 --> 01:09:23,172
the ocean chemistry is changing.
1133
01:09:23,256 --> 01:09:27,214
So, methane was in a kind of equilibrium
for some time,
1134
01:09:27,298 --> 01:09:32,631
and during the last couple of years,
we see quite a distinct increase in methane.
1135
01:09:32,714 --> 01:09:35,797
Do not know where this signal
is coming from,
1136
01:09:35,881 --> 01:09:38,505
and at the present time,
that, of course,
1137
01:09:38,589 --> 01:09:41,173
is putting a pressure
on the scientific community
1138
01:09:41,256 --> 01:09:43,548
to give an answer
to the politicians:
1139
01:09:43,631 --> 01:09:46,464
what is going on with the
methane in the atmosphere?
1140
01:09:46,547 --> 01:09:48,422
Where is the methane coming from?
1141
01:09:48,505 --> 01:09:52,298
What is presently
becoming more unstable?
1142
01:09:52,381 --> 01:09:54,838
We have done some
very comprehensive
1143
01:09:54,921 --> 01:09:56,963
measurement campaigns
where we have measured
1144
01:09:57,047 --> 01:09:59,881
at the sea floor, in the ocean,
1145
01:09:59,964 --> 01:10:03,130
at the sea surface,
and in the air at the same time
1146
01:10:03,213 --> 01:10:08,839
to understand how methane is
regulated in this whole system.
1147
01:10:08,922 --> 01:10:11,838
There is a lot of methane
stored at the sea floor,
1148
01:10:11,921 --> 01:10:15,213
and this is so much
that only a small change
1149
01:10:15,297 --> 01:10:19,630
might impact the ocean,
or the atmosphere.
1150
01:10:23,047 --> 01:10:26,006
The balance here
needs a lot more focus,
1151
01:10:26,089 --> 01:10:29,422
a lot more observations,
and combining atmosphere,
1152
01:10:29,505 --> 01:10:32,963
ocean, climate, different kind
of components together.
1153
01:10:35,422 --> 01:10:37,213
In my profession,
1154
01:10:37,297 --> 01:10:41,339
I'm interested in studying
methane cold seeps in the ocean,
1155
01:10:41,422 --> 01:10:44,422
in the Russian Arctic,
and also in the Barents Sea.
1156
01:10:44,505 --> 01:10:46,005
It's, well, basically,
1157
01:10:46,088 --> 01:10:48,213
streams of gas bubbles
rising from the sea floor,
1158
01:10:48,297 --> 01:10:52,713
and those gas bubbles are
mostly composed of methane gas.
1159
01:10:52,796 --> 01:10:55,505
First, it's gas hydrates,
that's solid form.
1160
01:10:55,589 --> 01:10:58,380
It's basically ice-like structures.
1161
01:11:00,380 --> 01:11:04,589
Also, the gas can be present as
free gas, which is gas bubbles.
1162
01:11:04,671 --> 01:11:08,172
Plumes of methane bubbles
can vary.
1163
01:11:08,255 --> 01:11:09,838
In some areas in the Arctic,
1164
01:11:09,921 --> 01:11:13,963
we find gas seeps as tall as
800, 900 meters.
1165
01:11:16,005 --> 01:11:17,464
And the water depth
in these areas,
1166
01:11:17,547 --> 01:11:20,088
a little more than 1,200 meters.
1167
01:11:20,172 --> 01:11:22,963
In shallower areas, we often
find gas seeps
1168
01:11:23,047 --> 01:11:25,380
that are almost reaching
the sea surface.
1169
01:11:25,464 --> 01:11:29,880
East Siberian Sea is definitely an area
of concern for guys studying methane,
1170
01:11:29,963 --> 01:11:32,255
in particular because
it's so shallow there.
1171
01:11:32,339 --> 01:11:37,630
So, those methane bubbles have really
high potential to get to the sea surface.
1172
01:11:37,713 --> 01:11:39,796
Some areas, Spitzbergen,
1173
01:11:39,880 --> 01:11:43,921
we find the methane flares that
are almost reaching the sea surface.
1174
01:11:51,087 --> 01:11:54,464
We have warmed the atmosphere
to such a degree
1175
01:11:54,547 --> 01:11:57,796
that we have hit the tipping
point of a melting Arctic.
1176
01:11:57,880 --> 01:12:00,754
We now face the potential
1177
01:12:00,837 --> 01:12:03,630
for an abrupt climate change scenario.
1178
01:12:03,713 --> 01:12:08,004
Current models predict we will shoot way
past the Paris Agreement,
1179
01:12:08,087 --> 01:12:11,047
to five degrees and more,
1180
01:12:11,130 --> 01:12:16,712
causing even more catastrophic
tipping points to be activated.
1181
01:12:16,795 --> 01:12:18,630
Warming might lead
1182
01:12:18,713 --> 01:12:22,130
to large injections of methane
into the atmosphere.
1183
01:12:22,213 --> 01:12:24,837
It's something we need
to be concerned about.
1184
01:12:24,920 --> 01:12:29,838
I would only add that it's one
of many possible stressors.
1185
01:12:29,921 --> 01:12:32,505
We move into a high-risk situation
1186
01:12:32,589 --> 01:12:35,754
where we don't really
have any experience
1187
01:12:35,837 --> 01:12:39,547
and we don't know how
to deal with it.
1188
01:13:00,421 --> 01:13:03,339
The permafrost,
and methane in general,
1189
01:13:03,422 --> 01:13:05,380
is of a great concern.
1190
01:13:05,464 --> 01:13:09,379
And I think that
this is something
1191
01:13:09,463 --> 01:13:13,796
perhaps we need to pay more
attention to methane in general,
1192
01:13:13,880 --> 01:13:16,670
in relation to the climate issue.
1193
01:13:16,754 --> 01:13:19,463
My concerns are that
1194
01:13:19,546 --> 01:13:23,754
there are great reservoirs
of methane in the world,
1195
01:13:23,837 --> 01:13:25,546
in particular in the Arctic.
1196
01:13:25,629 --> 01:13:28,589
It is the risk of going
beyond the tipping point
1197
01:13:28,671 --> 01:13:30,963
where it will be
difficult to go back
1198
01:13:31,047 --> 01:13:33,837
and reverse the problem.
1199
01:13:42,920 --> 01:13:48,213
It's a very plausible feedback
mechanism that in Arctic soils,
1200
01:13:48,297 --> 01:13:49,962
permafrost soils,
1201
01:13:50,046 --> 01:13:53,004
there's an enormous amount
of organic material frozen.
1202
01:13:53,087 --> 01:13:56,464
And the amount that is
available there, potentially,
1203
01:13:56,547 --> 01:14:00,920
to turn into CO2 and methane is
maybe three times, four times
1204
01:14:01,004 --> 01:14:04,671
all of the fossil fuels
that we have burned.
1205
01:14:11,588 --> 01:14:16,588
If we take all this material
out of the deep freeze...
1206
01:14:16,670 --> 01:14:20,963
you very likely get large CO2
and methane emissions
1207
01:14:21,047 --> 01:14:23,463
on a huge scale,
1208
01:14:23,546 --> 01:14:26,254
over which we have no control.
1209
01:14:29,921 --> 01:14:33,463
I study methane emissions
from lakes.
1210
01:14:33,546 --> 01:14:35,712
We are in interior Alaska,
1211
01:14:35,795 --> 01:14:39,172
and we are in discontinuous permafrost.
1212
01:14:40,712 --> 01:14:42,087
The thing that we're looking at
1213
01:14:42,171 --> 01:14:43,795
is microbial methane.
1214
01:14:43,879 --> 01:14:46,171
This methane bubbling here behind me,
1215
01:14:46,254 --> 01:14:48,754
it's dead plant
and animal remains
1216
01:14:48,837 --> 01:14:50,504
that were locked up in permafrost
1217
01:14:50,588 --> 01:14:52,463
for tens of thousands of years.
1218
01:14:52,546 --> 01:14:54,463
And as that permafrost is thawing,
1219
01:14:54,546 --> 01:14:57,962
the microbes eat that soil carbon,
1220
01:14:58,046 --> 01:15:00,004
and they turn it into methane.
1221
01:15:01,546 --> 01:15:04,129
This process of permafrost thawing,
1222
01:15:04,212 --> 01:15:08,171
and that thawing permafrost
fueling methane production,
1223
01:15:08,254 --> 01:15:11,129
and then methane
escapes into the atmosphere,
1224
01:15:11,212 --> 01:15:13,295
causes climate warming,
1225
01:15:13,378 --> 01:15:15,379
which causes more permafrost to thaw,
1226
01:15:15,463 --> 01:15:17,546
we call that a permafrost
carbon feedback.
1227
01:15:17,629 --> 01:15:19,171
It is a natural process.
1228
01:15:19,254 --> 01:15:21,004
Our concern, though,
1229
01:15:21,087 --> 01:15:23,421
is that as climate warms
1230
01:15:23,504 --> 01:15:27,296
at a faster rate than it has
in the last 10,000 years,
1231
01:15:27,379 --> 01:15:29,712
that permafrost
is going to respond
1232
01:15:29,795 --> 01:15:31,504
by thawing a lot more quickly
1233
01:15:31,588 --> 01:15:34,254
and releasing,
at a faster rate, methane gas.
1234
01:15:34,338 --> 01:15:37,004
Now every time
I go to a new lake,
1235
01:15:37,087 --> 01:15:39,253
I attempt to light
these gas pockets.
1236
01:15:39,337 --> 01:15:41,171
Because it's a very high
concentration of methane,
1237
01:15:41,254 --> 01:15:42,837
it's highly flammable,
1238
01:15:42,920 --> 01:15:45,504
we see a positive flame test
when they contain methane.
1239
01:15:45,588 --> 01:15:48,003
So it's a quick gas
chromatograph on the lake
1240
01:15:48,086 --> 01:15:49,712
to tell us do we have
a methane lake,
1241
01:15:49,795 --> 01:15:52,879
or are we dealing with
a different kind of lake?
1242
01:15:52,962 --> 01:15:55,836
There are many new lakes
forming that were not here
1243
01:15:55,919 --> 01:15:58,546
30 or 60 years ago...
1244
01:15:58,629 --> 01:16:04,003
and those lakes have 10 to 100 to 1,000 times
more methane than the rest of the lakes.
1245
01:16:06,254 --> 01:16:09,087
They are a picture of the type
of methane emissions
1246
01:16:09,171 --> 01:16:13,669
we expect to see
in the next 10 to 50 years
1247
01:16:13,753 --> 01:16:17,087
as permafrost warms and thaws,
1248
01:16:17,171 --> 01:16:19,546
and that permafrost feedback
cycle kicks in
1249
01:16:19,629 --> 01:16:21,170
and really accelerates.
1250
01:16:24,129 --> 01:16:27,212
Now, is it methane,
is it permafrost,
1251
01:16:27,296 --> 01:16:32,296
is it the dissolved organic carbon in the ocean
which is suddenly remobilized?
1252
01:16:32,379 --> 01:16:36,087
These things are all
intertwined with each other.
1253
01:16:36,171 --> 01:16:39,711
So, really what one
needs to ask is:
1254
01:16:39,794 --> 01:16:42,546
are there positive feedbacks
within the system?
1255
01:16:42,629 --> 01:16:44,254
The answer is yes.
1256
01:16:44,338 --> 01:16:47,919
So, it just stands to reason,
purely by common sense,
1257
01:16:48,003 --> 01:16:52,171
the less you disturb it,
the better off things will be.
1258
01:17:04,170 --> 01:17:09,754
We have the solutions at hand,
but the question still remains.
1259
01:17:09,837 --> 01:17:15,628
Can we mobilize and take collective action
before it's too late?
1260
01:17:15,711 --> 01:17:18,795
There isn't the oomph
in the world to do this.
1261
01:17:18,879 --> 01:17:22,253
They talk about,
with the Paris Agreement,
1262
01:17:22,337 --> 01:17:25,546
how we must reduce
our carbon emissions
1263
01:17:25,629 --> 01:17:29,128
and to keep temperature rise
at some low level,
1264
01:17:29,211 --> 01:17:32,545
but in fact, of course,
we won't be able to do that.
1265
01:17:34,463 --> 01:17:36,545
The technology that can save us
is something
1266
01:17:36,628 --> 01:17:39,878
that would take carbon dioxide
out of the atmosphere.
1267
01:17:42,086 --> 01:17:43,962
So it ought to be obvious
1268
01:17:44,046 --> 01:17:47,378
that the biggest research
effort that man is involved in
1269
01:17:47,462 --> 01:17:51,546
should be to develop direct
air capture methods that work.
1270
01:17:53,628 --> 01:17:56,003
If we do that,
then we can save the world,
1271
01:17:56,086 --> 01:17:58,462
and so why don't we do it?
1272
01:18:09,629 --> 01:18:12,128
Direct air capture is machines
1273
01:18:12,211 --> 01:18:15,836
which take in ambient air and
extract the CO2 from this air.
1274
01:18:15,919 --> 01:18:19,337
For the last ten years, we have
been working on direct air capture,
1275
01:18:19,420 --> 01:18:23,462
with the goal of making it with
the least possible energy impact,
1276
01:18:23,545 --> 01:18:25,628
and ultimately with the best economics.
1277
01:18:25,711 --> 01:18:29,503
This machine consists of four
40-foot shipping containers,
1278
01:18:29,587 --> 01:18:32,211
and can be any size,
there is no limit to it.
1279
01:18:32,295 --> 01:18:34,211
So we take in the ambient air here.
1280
01:18:34,295 --> 01:18:37,794
And inside,
we have our filter structure.
1281
01:18:40,003 --> 01:18:42,628
We get the waste heat
of the waste incinerated
1282
01:18:42,711 --> 01:18:43,961
to drive this plant.
1283
01:18:45,003 --> 01:18:46,711
Once the CO2 is captured,
1284
01:18:46,794 --> 01:18:49,378
this gas is then going
to a greenhouse,
1285
01:18:49,462 --> 01:18:51,711
and this greenhouse
is using the CO2
1286
01:18:51,794 --> 01:18:53,753
to increase the CO2 concentration
1287
01:18:53,836 --> 01:18:56,086
in the atmosphere of the greenhouse.
1288
01:18:56,170 --> 01:18:59,211
Which is done already nowadays,
but with fossil CO2,
1289
01:18:59,295 --> 01:19:02,628
and from tomorrow on, they're
going to use atmospheric CO2.
1290
01:19:06,587 --> 01:19:09,377
This plant will allow
to close a carbon cycle.
1291
01:19:09,461 --> 01:19:12,378
So, of course, the CO2
goes into the greenhouse,
1292
01:19:12,462 --> 01:19:15,128
and goes to the tomatoes
and cucumbers,
1293
01:19:15,211 --> 01:19:18,169
and once we eat them, the CO2
goes back to the atmosphere.
1294
01:19:18,252 --> 01:19:21,086
But since we recapture the CO2
from the atmosphere,
1295
01:19:21,170 --> 01:19:22,545
it's a closed cycle.
1296
01:19:22,628 --> 01:19:26,085
So, this can be a missing piece
of the pie
1297
01:19:26,169 --> 01:19:29,587
in order to close
a global carbon cycle
1298
01:19:29,669 --> 01:19:32,170
in the energy
or transportation sector.
1299
01:19:35,294 --> 01:19:38,462
So, besides using CO2
in a greenhouse like this,
1300
01:19:38,545 --> 01:19:41,587
we can take CO2,
we can take water,
1301
01:19:41,669 --> 01:19:43,294
and we can take
renewable energy.
1302
01:19:43,377 --> 01:19:47,503
We can again produce fuels--
for example, jet fuel.
1303
01:19:47,587 --> 01:19:52,294
In order to capture
1% of global CO2 emissions,
1304
01:19:52,377 --> 01:19:56,211
we would need roughly 300,000
of the plants behind me,
1305
01:19:56,295 --> 01:19:58,253
which is of course
a very high number.
1306
01:19:58,337 --> 01:20:01,294
But if you compare this
to existing infrastructures,
1307
01:20:01,377 --> 01:20:03,794
it's a scale
which humanity can handle.
1308
01:20:03,878 --> 01:20:07,669
So, it's definitely
an achievable goal.
1309
01:20:12,753 --> 01:20:16,502
The next project is to bring
a plant to Iceland
1310
01:20:16,586 --> 01:20:18,710
to capture CO2 from the air
1311
01:20:18,793 --> 01:20:23,086
and sequester the CO2 underground.
1312
01:20:23,170 --> 01:20:27,127
And in two hours, you literally
turn CO2 into a stone,
1313
01:20:27,210 --> 01:20:30,753
which stores it in a permanent
and safe manner.
1314
01:20:33,502 --> 01:20:37,377
In order to run the plant,
we would use geothermal heat.
1315
01:20:39,170 --> 01:20:41,337
There's an abundance of it
on Iceland,
1316
01:20:41,420 --> 01:20:44,419
therefore we would have
low carbon footprint energy
1317
01:20:44,502 --> 01:20:46,836
available to drive the machine.
1318
01:20:46,919 --> 01:20:48,753
So, today is a very special day.
1319
01:20:48,836 --> 01:20:52,835
We have brought CO2 capture
plant up here to Iceland.
1320
01:20:52,918 --> 01:20:55,337
And we are taking CO2
out of the air,
1321
01:20:55,420 --> 01:20:57,628
and then pumping it underground,
1322
01:20:57,711 --> 01:21:00,419
storing it in
the basalt rock formation
1323
01:21:00,502 --> 01:21:01,960
within the CarbFix project.
1324
01:21:02,044 --> 01:21:03,710
So, we extract CO2 from the air
1325
01:21:03,794 --> 01:21:07,044
and permanently remove it
by turning it into rock.
1326
01:21:07,127 --> 01:21:09,336
And yesterday night
was the first time
1327
01:21:09,419 --> 01:21:13,045
that atmospheric CO2
was injected into the ground.
1328
01:21:13,128 --> 01:21:15,502
We can go up to thousands,
ten thousands,
1329
01:21:15,586 --> 01:21:18,960
hundred thousands, and even up
to millions of tons of CO2
1330
01:21:19,044 --> 01:21:22,253
per year that can be extracted
from the atmosphere.
1331
01:21:22,337 --> 01:21:23,877
That is actually,
to our knowledge,
1332
01:21:23,960 --> 01:21:25,668
the first time ever
in the world
1333
01:21:25,752 --> 01:21:27,502
that direct air capture of CO2
1334
01:21:27,586 --> 01:21:30,587
has been combined
with underground safe
1335
01:21:30,669 --> 01:21:32,752
and permanent storage of CO2.
1336
01:21:36,002 --> 01:21:39,378
Yeah, it's a new relationship
with carbon.
1337
01:21:39,462 --> 01:21:40,877
Why can't we find a way
1338
01:21:40,960 --> 01:21:42,668
to make it an ingredient
for something?
1339
01:21:42,752 --> 01:21:44,544
Why can't we put it
in our plastics
1340
01:21:44,627 --> 01:21:46,085
or in our building materials?
1341
01:21:46,169 --> 01:21:48,711
Or through the help
of carbon dioxide chemistry,
1342
01:21:48,794 --> 01:21:52,169
turning carbon dioxide into the
things that we need every day?
1343
01:22:07,835 --> 01:22:13,085
I'm Daniel Nocera, the Patterson-Rockwood
professor of energy at Harvard University.
1344
01:22:13,169 --> 01:22:17,085
These are my labs,
the labs where we invented
1345
01:22:17,169 --> 01:22:19,502
the artificial leaf
and the bionic leaf.
1346
01:22:19,586 --> 01:22:24,502
And what they do
is a complete photosynthesis.
1347
01:22:24,586 --> 01:22:29,502
Sunlight, air and water,
to fuels and food.
1348
01:22:31,002 --> 01:22:33,044
Think about photosynthesis.
1349
01:22:33,127 --> 01:22:36,252
If you think about
what it really does,
1350
01:22:36,336 --> 01:22:38,668
it's the building block
of life,
1351
01:22:38,752 --> 01:22:40,752
and its building blocks,
literally,
1352
01:22:40,835 --> 01:22:45,294
are CO2, water, and sunlight.
1353
01:22:45,377 --> 01:22:48,543
And we build all of this,
like this,
1354
01:22:48,626 --> 01:22:53,877
wood and food,
and starch, and biomass.
1355
01:22:53,960 --> 01:22:57,001
That's a remarkable transformation.
1356
01:22:57,084 --> 01:23:01,169
This photosynthetic process,
it's very complex,
1357
01:23:01,252 --> 01:23:03,461
but we really listen to nature.
1358
01:23:03,544 --> 01:23:06,293
And that, we finally ended up
doing in 30 years.
1359
01:23:06,377 --> 01:23:09,002
And something that makes us
really happy,
1360
01:23:09,085 --> 01:23:12,502
not only can I say yes,
we can do it artificially,
1361
01:23:12,586 --> 01:23:16,461
I can do it ten times better
than photosynthesis.
1362
01:23:16,544 --> 01:23:20,586
We made special catalysts that
coated the artificial leaf,
1363
01:23:20,668 --> 01:23:24,419
and then they would split water
to hydrogen and oxygen.
1364
01:23:24,502 --> 01:23:28,169
The second part of the
invention is the bionic leaf.
1365
01:23:28,252 --> 01:23:31,501
It takes the hydrogen
from the bacteria
1366
01:23:31,585 --> 01:23:33,336
and then it makes fuels.
1367
01:23:33,419 --> 01:23:36,877
And so, depending on what genes
I put into the bacteria,
1368
01:23:36,960 --> 01:23:40,251
I could have the bacteria
make materials,
1369
01:23:40,335 --> 01:23:42,002
they could make drugs.
1370
01:23:42,085 --> 01:23:45,127
We've shown
they can make fertilizer.
1371
01:23:45,210 --> 01:23:48,335
We can work out of any water source,
1372
01:23:48,418 --> 01:23:52,127
including natural waters,
sea water.
1373
01:23:52,210 --> 01:23:54,127
As long as you have
my artificial leaf,
1374
01:23:54,210 --> 01:23:56,501
you can do it in your backyard.
1375
01:23:56,585 --> 01:24:01,586
We don't need to dig what's been
down there and release more CO2.
1376
01:24:01,668 --> 01:24:04,626
The artificial leaf,
working with the bionic leaf,
1377
01:24:04,709 --> 01:24:07,084
takes the CO2 out of the atmosphere,
1378
01:24:07,168 --> 01:24:09,544
uses sunlight and water,
and we make fuel.
1379
01:24:09,668 --> 01:24:14,959
So, we don't add any more
to the atmosphere, any more CO2.
1380
01:24:15,043 --> 01:24:19,210
And it's another issue, because
the cost I'm up against,
1381
01:24:19,294 --> 01:24:23,585
the developed world has spent
tens of trillions of dollars
1382
01:24:23,667 --> 01:24:25,084
to build what they now use.
1383
01:24:25,169 --> 01:24:26,835
It's kind of hard
to walk away from
1384
01:24:26,918 --> 01:24:29,293
a multi-trillion dollar investment
1385
01:24:29,376 --> 01:24:30,543
that you've paid off.
1386
01:24:30,626 --> 01:24:32,418
So, that's what it's all about.
1387
01:24:32,501 --> 01:24:37,667
Therefore, you need policy
and you need good partnership.
1388
01:24:37,751 --> 01:24:43,127
And the public informing them
that they have options,
1389
01:24:43,210 --> 01:24:46,959
and that there can be
this different world.
1390
01:24:51,001 --> 01:24:53,710
This new world
can be sustainable,
1391
01:24:53,793 --> 01:24:56,001
innovative, and profitable.
1392
01:24:56,084 --> 01:24:59,543
The green economy
is creating millions of jobs,
1393
01:24:59,626 --> 01:25:01,752
and will create millions more.
1394
01:25:01,835 --> 01:25:03,876
It matches and will surpass
1395
01:25:03,959 --> 01:25:07,126
the economy of the fossil fuel industry.
1396
01:25:07,209 --> 01:25:10,085
The challenge to reverse
climate disruption
1397
01:25:10,169 --> 01:25:13,251
opens up opportunity for everyone.
1398
01:25:13,335 --> 01:25:17,960
It is now more profitable
than ever to be green.
1399
01:25:21,959 --> 01:25:23,585
Up until recently,
1400
01:25:23,667 --> 01:25:27,918
the profit you could make
from creating the problem
1401
01:25:28,002 --> 01:25:30,876
was greater than the profit
1402
01:25:30,959 --> 01:25:32,501
you could make from the solutions.
1403
01:25:32,626 --> 01:25:35,043
So, the solutions
had to be done with subsidies,
1404
01:25:35,126 --> 01:25:37,418
which were rare and non-existent,
1405
01:25:37,501 --> 01:25:40,751
or altruism, or faith.
1406
01:25:40,834 --> 01:25:43,293
But people who are making
the problems were raking it in,
1407
01:25:43,376 --> 01:25:44,959
raking it in, raking it in.
1408
01:25:45,043 --> 01:25:47,084
And I think we're at a crossover
1409
01:25:47,168 --> 01:25:50,376
where actually the profit
you can make from the solutions
1410
01:25:50,460 --> 01:25:52,877
is greater than the profit
from the problems.
1411
01:25:52,960 --> 01:25:55,209
And that is not well understood.
1412
01:25:55,293 --> 01:25:57,751
So it's not that altruism
need not apply,
1413
01:25:57,834 --> 01:25:59,126
it's a great thing.
1414
01:25:59,209 --> 01:26:01,917
But actually,
altruism will not be needed
1415
01:26:02,001 --> 01:26:05,501
in order to move towards a world
where we reverse global warming,
1416
01:26:05,585 --> 01:26:08,543
because in fact,
it's less expensive.
1417
01:26:08,626 --> 01:26:12,834
It's more profitable,
more beneficial, more jobs.
1418
01:26:12,917 --> 01:26:15,460
It's the most amazing thing
that's happened
1419
01:26:15,543 --> 01:26:17,126
in the last few years,
1420
01:26:17,209 --> 01:26:19,667
and it's going to do
nothing but increase
1421
01:26:19,751 --> 01:26:21,001
as the years go by,
1422
01:26:21,084 --> 01:26:23,376
because engineers and designers,
1423
01:26:23,460 --> 01:26:25,709
and basically who
are unknown and unnamed,
1424
01:26:25,792 --> 01:26:28,834
have been working diligently,
and are working diligently
1425
01:26:28,917 --> 01:26:32,834
to reinvent a new way
of being a human being
1426
01:26:32,917 --> 01:26:34,751
relating to this planet.
1427
01:26:53,791 --> 01:26:57,460
In Orkney, we have a really
strong maritime tradition.
1428
01:26:57,543 --> 01:27:01,708
And since the '70s, the oil
and gas industry in Aberdeen
1429
01:27:01,791 --> 01:27:04,043
has been a major contributor
to the local economy,
1430
01:27:04,126 --> 01:27:06,293
providing tens and thousands of jobs.
1431
01:27:06,376 --> 01:27:07,959
But really,
in the last few years,
1432
01:27:08,043 --> 01:27:09,292
we've seen quite a big downturn
1433
01:27:09,375 --> 01:27:11,208
in terms of the oil and gas industry
1434
01:27:11,292 --> 01:27:12,751
and the price of oil.
1435
01:27:12,834 --> 01:27:15,418
But we've got lots
of really experienced people
1436
01:27:15,501 --> 01:27:17,875
in offshore operations
on our doorstep,
1437
01:27:17,958 --> 01:27:20,792
and they're finding new jobs
in offshore renewables
1438
01:27:20,876 --> 01:27:22,667
and companies such as ourselves.
1439
01:27:25,959 --> 01:27:29,709
Tidal energy is almost
an entirely untapped resource.
1440
01:27:29,792 --> 01:27:31,709
We think we have the potential
around the world
1441
01:27:31,792 --> 01:27:35,334
for about 100 gigawatts
of capacity, perhaps more.
1442
01:27:35,417 --> 01:27:38,501
And what that equates to
is a low-carbon energy
1443
01:27:38,585 --> 01:27:41,335
for millions and millions of homes.
1444
01:27:43,666 --> 01:27:46,125
What we've got here
is the world's most powerful
1445
01:27:46,208 --> 01:27:48,751
floating tidal energy generator.
1446
01:27:48,834 --> 01:27:50,585
We've got a floating platform
1447
01:27:50,667 --> 01:27:52,833
to which two rotors are mounted.
1448
01:27:57,709 --> 01:27:59,750
We start with the rotors turning,
1449
01:27:59,833 --> 01:28:01,334
which produces electricity,
1450
01:28:01,417 --> 01:28:03,042
which comes back up into the machine
1451
01:28:03,125 --> 01:28:04,418
where it's conditioned,
1452
01:28:04,501 --> 01:28:09,000
and then it gets transformed,
and stepped up,
1453
01:28:09,083 --> 01:28:11,666
and fed back into the grid.
1454
01:28:11,750 --> 01:28:13,667
It's like a wind turbine
on its side
1455
01:28:13,751 --> 01:28:16,084
with two rotors instead of one.
1456
01:28:16,168 --> 01:28:20,083
Two weeks ago,
we had great success.
1457
01:28:20,167 --> 01:28:24,084
First period of 24-hour continuous
generation from the device.
1458
01:28:24,168 --> 01:28:27,791
It actually operated
beyond expectations.
1459
01:28:27,875 --> 01:28:31,460
The device itself generated
over 18 megawatt-hours of power
1460
01:28:31,543 --> 01:28:33,750
in that 24-hour period.
1461
01:28:33,833 --> 01:28:37,125
We're converging on
more traditional methods
1462
01:28:37,208 --> 01:28:38,625
of renewable generation,
1463
01:28:38,708 --> 01:28:41,460
and really putting
tidal out there
1464
01:28:41,543 --> 01:28:44,125
as a real competitive technology
across the world
1465
01:28:44,208 --> 01:28:46,000
and the world's
generation needs.
1466
01:28:48,043 --> 01:28:51,584
The tidal turbine is,
it's 63 meters long in total.
1467
01:28:51,666 --> 01:28:54,292
We do all the power conversion
within the device itself,
1468
01:28:54,375 --> 01:28:56,292
and it's ready,
then, for export
1469
01:28:56,375 --> 01:28:58,460
right into the UK electricity grid.
1470
01:28:58,543 --> 01:29:02,500
So, you know, we're aiming
for tens of thousands
1471
01:29:02,584 --> 01:29:04,584
of these tidal turbines,
1472
01:29:04,666 --> 01:29:06,335
but this, you know,
fully integrated system
1473
01:29:06,418 --> 01:29:09,417
for producing low carbon energy,
so we're very excited about it.
1474
01:29:12,584 --> 01:29:15,293
So, EMEC was set up
as a testing laboratory,
1475
01:29:15,376 --> 01:29:17,833
because we know that
there's a huge amount of energy
1476
01:29:17,916 --> 01:29:20,708
in the oceans
all around the world,
1477
01:29:20,791 --> 01:29:23,335
and we're trying to find a way
to harvest it.
1478
01:29:23,418 --> 01:29:26,500
And so, we realized that one
of the most important things
1479
01:29:26,584 --> 01:29:28,916
was to have a test center
which would allow us
1480
01:29:29,000 --> 01:29:31,000
to find out how to do this properly.
1481
01:29:31,083 --> 01:29:33,417
So, what we've got
is a site here
1482
01:29:33,500 --> 01:29:35,500
where we've got cables
that are out in the sea
1483
01:29:35,584 --> 01:29:38,334
that allow developers
of these machines
1484
01:29:38,417 --> 01:29:40,543
to put these machines
on to our cables,
1485
01:29:40,626 --> 01:29:44,042
and the electricity
is then brought on to shore.
1486
01:29:44,125 --> 01:29:46,250
And that then feeds
into our national grid.
1487
01:29:46,334 --> 01:29:47,750
So, this is real.
1488
01:29:47,833 --> 01:29:50,459
This is making electricity
out of seawater.
1489
01:29:52,375 --> 01:29:54,791
So, at the moment, we've got
a device called the Penguin,
1490
01:29:54,875 --> 01:29:57,000
and that's by a company
called Wello Oy,
1491
01:29:57,083 --> 01:29:58,625
and their machine is effectively
1492
01:29:58,708 --> 01:30:01,958
a large pendulum inside a ship.
1493
01:30:02,042 --> 01:30:03,375
And as the ship moves,
1494
01:30:03,459 --> 01:30:05,208
this pendulum turns horizontally,
1495
01:30:05,292 --> 01:30:07,375
and that then generates electricity.
1496
01:30:07,459 --> 01:30:08,875
The sea is unrelenting,
1497
01:30:08,958 --> 01:30:11,042
and it will really try
and damage equipment.
1498
01:30:11,125 --> 01:30:13,708
So, making the equipment
as reliable, robust,
1499
01:30:13,791 --> 01:30:16,417
efficient, cost-effective,
all these things
1500
01:30:16,500 --> 01:30:18,167
are the things that people
are grappling with.
1501
01:30:18,250 --> 01:30:19,708
But the really clever thing is,
1502
01:30:19,791 --> 01:30:21,375
we have done that piece of alchemy.
1503
01:30:21,459 --> 01:30:23,624
We've actually turned seawater
into electricity.
1504
01:30:23,707 --> 01:30:27,125
And that really is huge,
because people are worried about
1505
01:30:27,208 --> 01:30:28,791
whether you can do this or not
for years,
1506
01:30:28,875 --> 01:30:30,083
and we've just shown you can.
1507
01:30:30,167 --> 01:30:32,207
And that's a big step forward.
1508
01:30:56,250 --> 01:30:59,124
No one can say that
the scientist has not warned,
1509
01:30:59,208 --> 01:31:03,750
has not told that we have to reduce
the emissions of greenhouse gases.
1510
01:31:03,833 --> 01:31:05,499
That should be clear to many.
1511
01:31:05,583 --> 01:31:06,874
How much farther can we go?
1512
01:31:06,957 --> 01:31:08,417
How many more tipping points
can we go
1513
01:31:08,500 --> 01:31:10,000
before we hit a tipping point
1514
01:31:10,083 --> 01:31:13,417
from which our civilization
cannot recover,
1515
01:31:13,500 --> 01:31:16,082
or from which the life
of this planet,
1516
01:31:16,166 --> 01:31:19,000
or a large portion of the life
on this planet cannot recover?
1517
01:31:19,083 --> 01:31:22,124
We cannot allow ourselves
to reach those points.
1518
01:31:22,207 --> 01:31:23,707
And we're so damn close to it.
1519
01:31:23,790 --> 01:31:25,625
We're at a turning point.
1520
01:31:25,708 --> 01:31:29,125
Either we can stay the course
and drown, burn,
1521
01:31:29,208 --> 01:31:30,957
and starve ourselves to death
1522
01:31:31,041 --> 01:31:32,957
in the face of the climate crisis,
1523
01:31:33,041 --> 01:31:36,208
or we can come together,
we can innovate.
1524
01:31:37,666 --> 01:31:38,915
Where do we stand?
1525
01:31:38,999 --> 01:31:41,458
Is it possible?
Is it game over?
1526
01:31:41,541 --> 01:31:43,083
Or is it, in fact, game on,
1527
01:31:43,167 --> 01:31:45,292
which is that we have at hand
1528
01:31:45,375 --> 01:31:48,291
the ability, capacity,
and solutions
1529
01:31:48,374 --> 01:31:50,082
that can reverse global warming,
1530
01:31:50,166 --> 01:31:52,958
not mitigate, not reduce,
not stabilize,
1531
01:31:53,042 --> 01:31:54,833
but reverse?
1532
01:31:54,916 --> 01:31:56,499
When you make your goals bigger,
1533
01:31:56,583 --> 01:31:57,999
it opens up possibility.
1534
01:31:58,082 --> 01:32:00,041
It opens up imagination.
1535
01:32:00,124 --> 01:32:03,167
It opens up innovation.
It doesn't foreclose.
1536
01:32:03,250 --> 01:32:05,166
It actually does the opposite.
1537
01:32:05,249 --> 01:32:08,458
And so, it's not that
there's one solution,
1538
01:32:08,541 --> 01:32:12,375
but together,
you can achieve drawdown
1539
01:32:12,459 --> 01:32:15,249
by doing 80% of the solutions.
1540
01:32:15,333 --> 01:32:19,167
Every one of them
has so many cascading benefits,
1541
01:32:19,250 --> 01:32:21,166
makes a better world
for everybody.
1542
01:32:21,249 --> 01:32:25,749
So, we don't lose
by understanding
1543
01:32:25,832 --> 01:32:27,500
that climate change is happening
1544
01:32:27,584 --> 01:32:30,915
and responding to it,
so what's the problem?
1545
01:32:38,124 --> 01:32:39,874
We are the first generation
1546
01:32:39,957 --> 01:32:42,624
to see the advance
of climate disruption,
1547
01:32:42,707 --> 01:32:46,125
and the last with a chance to fix it.
1548
01:32:46,207 --> 01:32:48,249
In spite of all this evidence,
1549
01:32:48,333 --> 01:32:50,790
we are currently
burning fossil fuels
1550
01:32:50,874 --> 01:32:53,375
at an ever-increasing rate.
1551
01:32:53,459 --> 01:32:55,207
We have heard from the scientists
1552
01:32:55,291 --> 01:32:59,874
who have told us the truth
based on actual research.
1553
01:32:59,957 --> 01:33:03,583
It is time to end the delay,
to listen,
1554
01:33:03,665 --> 01:33:07,041
and to implement
the solutions at hand.
1555
01:33:07,124 --> 01:33:11,707
Time is running out.
The ice is melting.
1556
01:33:11,790 --> 01:33:15,583
Decisive action
must be taken now.
1557
01:33:15,665 --> 01:33:18,124
There is no other option.
1558
01:33:18,207 --> 01:33:21,665
This moment is within our reach.
1559
01:33:21,749 --> 01:33:23,790
Let us grasp it.
1560
01:33:23,874 --> 01:33:27,291
It is up to us,
each one of us,
1561
01:33:27,374 --> 01:33:32,624
to save this unique blue planet
for generations to come.
