Summer weather is getting 'stuck' due to Arctic warming

Rising arctic temperatures mean we face a future of 'extreme extremes' where sunny days become heatwaves and rain becomes floods, study says

Summer weather patterns are increasingly likely to stall in Europe, North America and parts of Asia, according to a new climate study that explains why Arctic warming is making heatwaves elsewhere more persistent and dangerous.

Rising temperatures in the Arctic have slowed the circulation of the jet stream and other giant planetary winds, says the paper, which means high and low pressure fronts are getting stuck and weather is less able to moderate itself.
