It’s widely known that the Earth’s average temperature has been rising. But new research finds that spatial patterns of extreme temperature anomalies — readings well above or below the mean — are warming even faster than the overall average. It may seem counterintuitive that global warming would be accompanied by colder winter weather at some locales. But scientists say the observation aligns with theories about climate change, which hold that amplified warming in the Arctic region produces changes in the jet stream, which can result in extended periods of cold weather at some locations in the mid-northern latitudes.
