Come dive into one of the curiously delightful conversations overheard at National Geographic’s headquarters, as we follow explorers, photographers, and scientists to the edges of our big, weird, beautiful world. Hosted by Peter Gwin and Amy Briggs.
The desolate Alaskan tundra - a landscape that has literally been frozen solid for thousands of years - is suddenly caving in on itself.

Beavers can survive in the arctic because - like people - they change the environment to make homes for themselves, and their carbon footprint can be seen from space.

Not only is methane a greenhouse gas, it's also flammable. Watch Katey Walter Anthony set frozen lakes on fire.
