It’s rare that winter weather reaches these extremes.
On this edition of River to River, host Ben Kieffer speaks to professor of meteorology Alan Czarnetzki about the prolonged polar plunge gripping the country. Czarnetzki also explains why this polar vortex has delivered the most extreme winter weather in years.
Iowa Public Radio’s Kate Payne joins the conversation to talk about a bill in the Iowa Legislature that would offer the possibility of parole for some Iowans serving a life sentence and Grant Gerlock updates us on how Iowa schools are coping with the cold in addition to COVID-19.
Later in the program, Iowa State University wildlife biologist Jim Pease describes how creatures great and small are coping with frigid temps.
