So what we're doing is, we're taking the most concentrated greenhouse gas sink, twice as much greenhouse gases are sequestered in the boreal per acre than the tropical rainforests.

like the Amazon rainforest you're hearing behind me.

And that's what we're doing.

The blue is cold and the red is warm.

(whether you're talking about Celsius or Fahrenheit)

UNESCO Cultural Heritage site.

There is less heat in the air at 3 than at 1 .

I'll just run them very quickly through.

I really like today.

I love that you get cold when it's 71 degrees out.

Our country's climate is temperate.

Unfortunately, when I was there I couldn't find one of them, but you have the antlers as proof.

Kind of.

The western border of the boreal in British Columbia is marked by the Coast Mountains, and on the other side of those mountains is the greatest remaining temperate rainforest in the world, the Great Bear Rainforest, and we'll discuss that in a few minutes in a bit more detail.

In the boreal, they are also the home where almost 50 percent of the 800 bird species found in North America migrate north to breed and raise their young.

Well, if it only got 1 colder it would be at 2 , but we know we have to go 4 colder.

And if it's still not obvious to you, you could also think of them in temperature, in temperature terms.

Trapped underneath the boreal forest and wetlands of northern Alberta are these vast reserves of this sticky, tar like bitumen.

In cold weather we must be sure to keep our bodies warm.

All across the boreal, we're blessed with this incredible abundance of wetlands.

Man, too, has been given protective devices against extreme temperatures.

An important impact, if global warming continues, will be on the breadbasket of our nation and the world, the Midwest and Great Plains, which are expected to become prone to extreme droughts, worse than the Dust Bowl, within just a few decades, if we let global warming continue.

The tar sands could threaten not just a large section of the boreal.

They're ocean based and scale animals who are communicating over much longer ranges than we had anticipated.

I am cold

Arctic, freezing, frigid.

In Ontario, the boreal marches down south to the north shore of Lake Superior.

A second item on my checklist is climate change.

It's cold.

It is cold.

Brrr, it's cold!

Ugh oh 우영

It's cold

It's cold

It's cold

It's cold!

What is it?

are you cold?

Why red socks with black shoes?

It's really cold.

It's cold.

I'm freezing.

So cold...

They grow in tropical forests like this one and they also grow in temperate rainforests, that we find in Washington state.

Siberia most of you probably think of as a cold, desolate, unlivable place.
