From a South African news source (via ThinkProgress) is news that the Artic ice is disappearing faster than anyone imagined. The photo to the left shows the effect of 24 years of global warming. The report that shocks scientists is that the ice pack has shrunken nearly in half in just the last three years. The waters from Sweden (the land at the top of the photo) to the North Pole is now ice free.
I know what my right-wing friends (acquaintances ... annoying neighbors) will say. They will say that global warming will be the greatest thing to happen to the Earth since pre-packaged spinach. Here is a Cato Institute love fest for heat.
What's the downside? This is a slide from a University of Florida "Biology for Engineers" lecture. If all the polar ice melts, Florida and Louisiana will disappear. The Mississippi River will flood to and consume Memphis. Eleven of the country's 25 largest cities will be inundated, including Washington D.C. Maybe this will catch the President's eye, a quarter of Texas will be underwater. To balance Cato, here is a National Resources Defense Council article.
