Study challenges climate change's link to our wild winter jet stream
Dartmouth study challenges the idea that climate change is behind the erratic wintertime behavior of the polar jet stream, the massive current of Arctic air that regulates weather for much of the Northern Hemisphere.
Large waves in the jet stream observed since the 1990s have, in recent years, driven abnormally frigid temperatures and devastating winter storms deep into regions such as the Space is hard. There is no excuse for pretending it’s easy.
