The middle panel illustrates spatial patterns of temperature anomalies for April 1998. The top panel shows locations that are below the 25th percentile, and the bottom panel shows locations that are above the 75th percentile.
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.”
