You don't really have to go to the ends of the earth to witness the effects of climate change, but it does help.

Among the scientists who work at the poles, there is not one scintilla of doubt.

Basically the world's ice zones are melting and they're seeing it.

Hi, I'm Rick Steeves.

Then montane spent five months on the Antarctic Peninsula learning from scientists and observing the Adelei penguins. We'll learn today on

travel with Rick Steve's how their harsh and beautiful world is facing an

accelerated threat from global warming. We'll also look north with

wilderness photographer Stephen Kauslowski. From his years in the Arctic, he's seen

how climate change is threatening not only wildlife, but the native people who depend on it for their survival.

And we'll have to undergo a lot of changes as the polar bear is going to have to undergo to survive.

Come along as we hear what the stark and fragile setting of the polar regions has to teach us in the hour ahead.

It's Travel with Rick Steves.

They're awesome places of stark raw beauty in a brutal climate.

Hi, I'm Rick Steeves.

Our guest today on Travel with Rick Steeves have spent time in the Arctic and Antarctic,
