The Conversation

The Conversation reporter Stacy Morford spotlights research by climatologist Judah Cohen and atmospheric scientist Mathew Barlow, which shows how changes in the Arctic can lead to changes in the stratospheric polar vortex, and cold waves in North America and Asia. “Our research reinforces two crucial lessons of climate change: First, the change doesn’t have to occur in your backyard to have a big effect on you,” write Cohen and Barlow. “Second, the unexpected consequences can be quite severe.”
