What Happens in the Arctic Doesn't Stay in the Arctic

Guest: Dr. Jennifer Francis, Woodwell Climate Research Center When we think about the Arctic, it's easy to picture a remote landscape of sea ice and polar bears. But what happens in the far north doesn't stay there. As the Arctic continues to warm at an unprecedented pace, scientists are uncovering how those changes may be influencing weather patterns across the Northern Hemisphere—from prolonged heat waves and persistent droughts to heavy rainfall and unusual swings in the jet stream. Today on Weather Geeks, we're joined by atmospheric scientist Dr. Jennifer Francis, whose pioneering research has helped shape our understanding of the connection between Arctic climate change and the behavior of the jet stream. We'll explore why the Arctic is warming so rapidly, how those changes can ripple through the atmosphere, and what they may mean for the persistent weather patterns we've seen in recent years—including the extreme heat that has gripped much of Europe this summer.
