How a warmer Arctic could intensify extreme weather


As the Arctic thaws, its atmosphere is changing and disrupting global weather.

Is there a link between the vanishing Arctic sea ice and extreme weather?

Some prominent climate researchers think so. That’s because warming temperatures in the Arctic are altering the behavior of the polar jet stream, a high-altitude river of air that drives weather patterns across the globe. As the winds that propel the jet stream weaken, storms, droughts, and extreme heat and cold move over continents at slower rates, meaning bad weather can stick around for longer.

Eli Kintisch reports aboard the Norwegian research vessel Helmer Hanssen about how changing conditions at the top of the world could be impacting weather far away.
