Bear: These emperor penguins
are about to undertake

One of the greatest feats of
endurance on the planet.

A single egg.

It's taken almost all this
mother's energy to create.

Time to entrust
it to her mate.

While she leaves
to feed at sea.

Now it's up to dad.

He must carry the egg through
the world's worst winter.

(wind howling).

Risk his own life to keep the
chick growing inside alive.

Just one of the many
remarkable stories of how

Life triumphs at the
ends of the earth.

(theme music plays).

When winter hits
the polar regions,

The temperature
can drop as low as

Minus 120 degrees fahrenheit.

Almost nothing grows.

Winds build into some of
the strongest on earth.

You've got land and
sea locked in ice.

And weeks of
perpetual darkness.

Only a few remarkable
animals have what it takes

To survive here, and
every day is a struggle

Against the elements
and each other.

(growling).

Now the poles are
changing faster than

Anywhere else on the planet.

(crashing).

And getting through
the coldest days,

That's just the
beginning of the battle.

Late fall.

Polar bears are grounded.

Once the sea has frozen over

They can head out
and begin hunting.

But since the 1970s
that's taking longer.

Hunger claws for an
extra three weeks.

And this young male must
face other challenges.

An older rival.

(growling).

(growling).

(growling).

The largest of
all land predators.

Male polar bears lead
a life of violence.

But today punches
are being pulled.

Sparring partners
test strength and skill.

Preparing for tougher times.

When the battle for food
and mates will be real.

(growling).

But first, patience.

Wait for winter.

The magic number.

28.8 fahrenheit.

Sea water begins to freeze.

An ice kingdom is born.

Almost limitless
hunting grounds.

The harshest season is
when polar bears thrive.

The arctic plunges
into 24 hours of night.

Around the poles the planet's
magnetic field puts on an

Unearthly display.

In the north the
aurora borealis.

And in the south
the aurora australis.

Winter here looks heavenly.

But for these emperor
penguins it's hell on earth.

All of them are male.

And if the eggs they're
carrying are to survive,

All of them must stand strong.

(wind howling).

Each one takes their turn in
the full force of the wind.

All the time balancing
their eggs on their toes.

Just beyond the
ices deadly reach.

(wind howling).

(penguin call).

75 days of
sacrifice finally over.

(penguin calls).

It was worth it.

(penguin calls).

Just 6 ounces, he's got
a lot of growing to do.

Soon the ice on which
they stand will all be gone.

This is canada's last land
before the arctic pack ice.

Somehow an eight-strong
pack of arctic wolves

Survives here.

(yipping).

During the brutal winter

Finding food is
a daily struggle.

But after almost three months
of darkness a ray of hope.

(barking).

Arctic hares are one of
the few other creatures

That survive here.

Gathering in huge
groups offers protection.

And now the sun has returned,

The element of
surprise is gone.

♪ ♪

A lot of effort for no return.

There are bigger
opportunities here,

But they come
with greater risks.

Musk oxen.

One of the
arctic's true survivors.

Bear: In their search for
food the arctic wolf pack

Can cover 50 miles in a day.

These musk oxen have
spent all winter

In this frozen waste land.

They're built to survive.

But just one adult
would feed the entire pack.

To witness wolves hunt musk
oxen in winter is so rare

It's never been captured
on camera, until now.

(rumbling).

This herd has a youngster.

(rumbling).

(whining).

But it's protected
behind a united front.

Armed with slashing horns,

Adults weight up to 700 pounds.

(rumbling).

(bellow, whining).

The wolves search for
weakness in their defense.

Try to get them on the run.

(snorting).

(growling, barking).

The mother won't
leave her calf,

But her instincts
work against her.

(growling, barking).

(grunting).

(growling, barking).

(rumbling).

In such a brutal landscape,
one animal's survival often

Depends on another's fate.

In the south, the
sun's power is increasing.

(chattering, calling).

It's been 12 weeks
since he hatched.

In fewer than four months,
all this will have melted.

By then chicks must
be ready to swim.

(chattering, calling).

His life depends on
how quickly he grows.

(chirping).

In just 150 days his body
weight must increase 70 times.

(chirping, calling).

Strengthening sun
promises easier times.

But down here
promises are easily broken.

Antarctica's freezing winds
have become more ferocious.

(howling wind).

A hole in the planet's
ozone layer is disrupting

The atmosphere,
altering the weather.

(howling wind).

Even though dad hasn't
returned from fishing,

The chick now
needs so much food,

Mum must go too.

His instincts are to follow.

But it's a mistake.

He's walking away from safety.

(calling).

(calling).

Unless he makes it
back to the colony,

He will die.

(penguin calls).

Bear: In antarctica
a storm has hit the

Emperor penguin colony.

It's taken a heavy toll.

(calling).

But most have survived,
keeping each other alive.

Separated chicks must
now find their parents.

(calling).

Somewhere amongst
17,000 penguins,

Is his father.

(calling).

His call is unique.

Reunited and safe.

These chicks have learned
an important life lesson.

The colony only
survives by standing together.

Spring races
across the arctic.

The change brings
new challenges.

A young female.

She depends on seals for food.

The only prey with enough
calories to sustain her.

As the ice melts, escape
routes are now everywhere.

Her chances plummet.

(sniffing).

Bears have an
acute sense of smell.

(sniffing).

They can detect seals
from nearly 2 miles.

This one's closer.

A huge male, he
needs food too,

And he doesn't
care how he gets it.

(grunting).

(cawing).

(roaring).

Just bones.

She's taken her fill.

Now she must leave.

A hungry male polar
bear can turn cannibal.

Summer in the poles has always
been a time of transformation.

But now the arctic is
changing faster than

At any rate in recorded history.

The climate is warming.

Polar bears face
immediate survival choices.

Head deeper in to the
ice or swim for land.

Either way four
lean months lie ahead.

Climate change at the poles
will bring challenges for

Many, but for some
it's opportunity.

Over 50 years the average
temperature here has risen

By around 5 degrees fahrenheit.

Gentoo penguins like
it warmer than their

Ice loving emperor cousins.

It exposes the bare rock
they need for nesting.

The waters here are so
rich successfully raising

Two chicks is far more likely.

(chirping, calling).

Who'll feed first is
decided by a chase.

(chirping, calling).

Chicks are at all stages.

The oldest are
ready for the sea.

But they're first taste of the
ocean may also be their last.

Bear: A changing climate
around antarctica is helping

Gentoo penguin populations.

But even in summer conditions
can deteriorate rapidly.

Storms blow brash
ice into shore.

The route back to
the colony is blocked.

Fledglings must negotiate
a maze of floating ice.

It's all too easy
to get left behind.

(chirping, calling).

And that's not
the only danger.

Pushing through
brash ice is hard work.

But this is not a
safe place to rest.

The one that got away.

Still, there's plenty of
other penguins to play with.

Summer intensifies.

Ice continues to retreat.

Polar bears are stranded.

Their toughest time.

Surviving on fat
built up last winter.

Reserves are running low.

There's almost nothing to eat.

Almost.

(sniffing).

At this time of year
beluga whales arrive

In canada's shallows.

A sanctuary for newborns.

These waters can be 18 degrees
warmer than the open sea.

(clicking, whistling).

This could be his life line.

They're tantalizingly close.

(squeaking, clicking).

One of the few whales
with flexible necks.

The belugas
easily see him coming.

With each dive, he
wastes precious energy,

And his chances of
surviving summer get slimmer.

Ar: On the shores of hudson
bay a hungry polar bear is

Desperately trying to
hunt beluga whales.

Catching them in open water
has proved almost impossible.

(squeaking, clicking).

But he can't let this
opportunity slip away.

A change in tactic.

From the rock prey
is easier to spot.

If only they
would come in range.

Built for the cold,
suffering in the sun.

♪ ♪

Finally.

A calf.

Not fat like an adult
but perhaps just enough

To keep starvation at bay.

Hunting beluga whales might
make the difference between

Life and death
for these bears.

But if the ice-free
season gets longer.

Even this may not be enough.

Polar animals have evolved
to survive the coldest,

Harshest conditions on earth.

But now the polar regions
are warming more rapidly

Than anywhere else.

This means new
opportunities for some,

But for the most cold adapted,

There are seriously
challenging days ahead.

The question is, can they
find new ways to adapt

To a fast changing world.

The emperor penguin parents
are on the home stretch.

Together they have traveled
thousands of miles

Keeping their chicks fed.

He hatched out
at under a pound,

Now he's over 20, almost

This family have done
everything they can,

In the hope that their
