Arctic Ice Melt Could Mean More Extreme Winters For U.S. And Europe

The record loss of Arctic sea ice this summer will echo throughout the weather patterns affecting the U.S. and Europe this winter, climate scientists said on Wednesday, since added heat in the Arctic influences the jet stream and may make extreme weather and climate events more likely.

The “astounding” loss of sea ice this year is adding a huge amount of heat to the Arctic Ocean and the atmosphere, said Jennifer Francis, an atmospheric scientist at Rutgers University in New Jersey. “It’s like having a new energy source for the atmosphere.” Francis was one of three scientists on a conference call Wednesday to discuss the ramifications of sea ice loss for areas outside the Arctic. The call was hosted by Climate Nexus.
