I don’t listen to many podcasts, but I made an exception for this one. One of my favorite climatologists, Deke Arndt of the National Centers for Environmental Information, talks to UGA Professor Dr. Marshall Shepherd of the Weather Channel‘s Weather Geeks about the differences between weather and climate, and climate change myths, and takes us on a tour of climate changes across the globe. It’s about 40 minutes long and worth every second. You can listen to it here.
