<P><B>Exploring one of the greatest potential contributors to climate change—thawing permafrost—and the anxiety of extinction on an increasingly hostile planet</B><BR/><BR/> </P><P>Climate scientists point to permafrost as a “ticking time bomb” for the planet, and from the Arctic, apocalyptic narratives proliferate on the devastating effects permafrost thaw poses to human survival.
