No Need to Rearrange the Deck Chairs--the Iceberg's Melting.
Previous estimates of the effects of global climate change include the melting of the ice pack on Greenland as a "worst-case" scenario. Guess what? The climate models underestimate the rate at which the pack-ice is melting, and also the amount of carbon that melting permafrost will inject into the atmosphere. Greenland is losing 52 cubic miles of ice each year, and the permafrost emits three to six times as much greenhouse gas as the entire U.S. car and light truck fleet. Meanwhile, the G8 and the United States Congress fiddle while the planet burns.
