A thaw from global warming is predicted to release the methane in the tundra — a greenhouse gas — and so make things still warmer yet.

What's so frightening to them is that after one of the regular warming periods begins, they can see (in air bubbles trapped in glaciers from those past times) that CO2 starts increasing, and they know that this is because of the warming and thawing of vast natural stores of carbon dioxide in the oceans — as well as in the frozen or frigid earth of the northern tundra.
