Americans may have to make serious changes to cope with global warming, including altering the way water is managed in the West, beefing up public health programs, and building higher bridges, according to preliminary findings from the federal U.S. Global Change Research Program. The researchers will issue a final report this summer on the affects of climate change in the U.S. They say that some warming is inevitable, so we will need to try to avoid the worst consequences. Westerners might face more frequent floods and droughts, people in the Midwest and Northeast might have to deal with more killer heat waves, and Southerners could see a decline in trees and birds.
