Global Warming Is Real - Just Visit Alaska

Skeptics of global warming should come to this Eskimo village on the Arctic Ocean, roughly 250 miles north of the Arctic Circle. It's hard to be complacent about climate change when you're in an area that normally is home to animals like polar bears and wolverines, but is now attracting robins.

A robin even built its nest in town this year (there is no word in the local Inupiat Eskimo language for robins). And last year a (presumably shivering) porcupine arrived.

The Okpilak River valley was historically too cold and dry for willows, and in the Inupiat language "Okpilak" means "river with no willows." Yet a warmer, wetter climate means that now it's crowded with willows.

In the past, I've been skeptical about costly steps (like those in the Kyoto accord) to confront climate change. But I'm changing my mind. The evidence, while still somewhat incomplete, is steadily mounting that our carbon emissions are causing an accelerating global warming that amounts to a major threat to the world in which we live.

Alaska has warmed by eight degrees, on average, in the winter, over the last three decades, according to meteorological records. The U.S. Arctic Research Commission says that today's Arctic temperatures are the highest in the last 400 years, and perhaps much longer.
