"Global warming will be twice as severe as previous estimates indicate, according to a new study published this month in the Journal of Climate, a publication of the American Meteorological Society.
The research, conducted by the Massachusetts Institute of Technology (MIT), predicts a 90% probability that worldwide surface temperatures will rise more than 9 degrees (F) by 2100, compared to a previous 2003 MIT study that forecast a rise of just over 4 degrees.
The Intergovernmental Panel on Climate Change in 2007 forecast a temperature rise of anywhere from 2 to 11 degrees by 2100 based on a variety of different greenhouse-gas-emissions scenarios."
