By: Mark Leon Goldberg on November 03, 2009 I am looking forward to Angela Merkel’s address to the U.S. Congress today. (Watch it live). Next Monday is the 20th anniversery of the fall of the Berlin Wall. Knowing Merkel, I expect her to use the platform to impress upon the U.S. Congress the neccesity of reaching an international agreement to combat climate change. Merkel, perhaps more so than any other western leader, is on the vanguard of the climate change debate. Unfortunately, the United States Senate is not quite there.
