The American Radio Works radio documentary programs have been garnering acclaim over the past few years, and their latest production is definitely worth a listen. Created by Daniel Grossman and John Rudolph (and narrated by Ira Flatow), this one-hour program addresses the effects that global warming may have on the northern half of the United States over the coming years and decades. The radio program itself is divided into three sections, including one that deals with ice cores and their use in paleoclimatology, the nature of the great ocean conveyor belt, and what might be done to prevent a climatic catastrophe. The site is also complemented by a fine selection of external weblinks, including those leading to the Pew Center on Global Climate Change and the National Renewable Energy Laboratory.
