Polar Vortex Driving Arctic Temps in Illinois (rebroadcast)
On January 28, 2019, much of the state woke up to sub-zero Arctic temperatures, caused by the polar vortex. The polar vortex is splitting again, potentially pushing cold air away from the poles and into other parts of the world — maybe even the midwest again like we saw in 2019? Could severe cold snaps like this become more common because of climate change?
To discuss those questions, The 21st was joined by two weather experts.
Trent Ford, Illinois State Climatologist at the University of Illinois at Urbana-Champaign
Carl Schreck, Weather scientist with NC State University, NOAA's National Centers for Environmental Information
