Kevin and Guy were again joined by Jim Massa, a science educator with broad experience in teaching students of various ages. We discussed Massa’s ongoing efforts to teach the masses about climate change, oceanography, paleontology, and other matters of environmental importance. Jim joined us earlier this year for the January 2021 episode of Nature Bats Last (https://naturebatslast.podbean.com/e/nature-bats-last-jim-massa-010520/).
