Arctic Warming Amplifies Extreme Weather Events Globally: Wildfires, Flooding Likely to Be More Severe

Warming in the Arctic is causing the jet stream, a belt of air held "up" around the Arctic by the temperature difference between the Arctic and warmer climates, to weaken and slow.  This is resulting in "stuck" weather patterns, according to a new review paper published in Nature Communications Monday. What would normally be a short-term heat wave, for example, is sticking around for considerably longer, exacerbating extreme weather events that remain in place for longer than normal.  While winter weather patterns have been the focus of many studies, the new research finds plenty of evidence for this weather stalling during the summer, when heat waves are particularly dangerous.  Read more...
