[font size=3]BLOOMINGTON, Ind. -- 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.

“Average temperatures don’t tell us everything we need to know about climate change,” he said. “Arguably, these cold extremes and warm extremes are the most important factors for human society.”

Robeson is the lead author of the article “Trends in hemispheric warm and cold anomalies,” which will be published in the journal Geophysical Research Letters and is available online. Co-authors are Cort J. Willmott of the University of Delaware and Phil D. Jones of the University of East Anglia.
