New MIT report predicts serious future warming

Global temperature is likely to rise 3.3-5.6 degrees Celsius by the end of this century, unless international climate negotiations in Paris next year are more effective than expected, according to a report released Monday by the MIT Joint Program on the Science and Policy of Global Change. The predicted temperature increase surpasses the threshold identified by the United Nations as necessary to avoid the most serious impacts of climate change, altering precipitation patterns and heightening the pressures of population and economic growth.

“Our world is rapidly changing,” says John Reilly, co-director of the MIT Joint Program and a coauthor of the report. “We need to understand the nature of the risks we’re facing so we can prepare for them.”
