NASA: U.S. may face extreme summer temperatures Average summer high temperatures of 110 in Chicago, D.C. by 2080 mongabay.com May 9, 2007 A new NASA study warns that the eastern United States could experience extreme warming by 2080, with average summer temperatures rising 10 degrees Fahrenheit. "There is the potential for extremely hot summertime temperatures in the future, especially during summers with less-than-average frequent rainfall," said lead author Barry Lynn of NASA's Goddard Institute for Space Studies and Columbia University, New York.
The study, based on three decades of observational temperature and precipitation data, used computer model simulations factored in expected soil, atmospheric, and oceanic conditions and projected 2 percent annual rise in greenhouse gases. The authors say their model is more accurate than global models used by the Intergovernmental Panel on Climate Change (IPCC). 2006 was the third warmest year on record for the United States, just cooler than 1998 and 1934, while the 2006-2007 winter was the warmest ever. Last month researchers at Columbia University's Lamont Doherty Earth Observatory warned that climate change could turn the American southwest into a "Dustbowl."
