There’s a polar bear meeting in Norway this week, where politicians are considering how to handle the dire predictions surrounding the fate of our arctic friend. And this meeting got us thinking: in the face of a warming globe, is extinction the only option? Are organisms, along with a little thing called natural selection, finding a way to beat this formidable foe? We hope Warren Allmon, a paleontology professor at Cornell who specializes in macroevolution, can shed some light on our queries. Mr. Allmon is also the director of the Museum of the Earth.
