It’s widely known that the Earth’s average temperature has
been rising. But research by an Indiana University geographer and colleagues
finds that spatial patterns of extreme temperature anomalies -- readings well
above or below the mean -- are warming even faster than the overall average.
And trends in extreme heat and cold are important, said
Scott M. Robeson, professor of geography in the College of Arts and Sciences at
IU Bloomington. They have an outsized impact on water supplies, agricultural
productivity and other factors related to human health and well-being.
