"Heatwaves, Rains May Become More Severe As Weather Stalls-Study"

"OSLO - Scorching summer heatwaves and downpours are set to become more extreme in the northern hemisphere as global warming makes weather patterns linger longer in the same place, scientists said on Monday.

They said there was a risk of “extreme extremes” in North America, Europe and parts of Asia because manmade greenhouse gas emissions seemed to be disrupting high-altitude winds that blow eastwards in vast, looping “planetary waves”.

“Summer weather is likely to become more persistent - more prolonged hot dry periods, possibly also more prolonged rainy periods,” said Dim Coumou, lead author of the study at the Potsdam Institute for Climate Impact Research (PIK) and Vrije Universiteit Amsterdam."
