NASA: Summer Extremes Getting More Extreme in Northern Hemisphere

Posted on January 23, 2013

NASA's statistical analysis of decades of Northern Hemisphere temperature data indicates that people living north of the equator are experiencing a greater frequency of extreme summer heat waves. The data indicates hotter summers are becoming the new normal.

James Hansen of NASA's Goddard Institute for Space Studies (GISS) in New York, says in a release, "Such anomalies were infrequent in the climate prior to the warming of the past 30 years, so statistics let us say with a high degree of confidence that we would not have had such an extreme anomaly this summer in the absence of global warming."
