The geologic record of Earth is an archive of data on the causes and effects of changing climates. As climate changes, it impacts everything from plants and animals to rocks and rivers. The study of ancient climates is paleoclimatology, and it’s important not only for our understanding of climate in the past, but also for teasing out what’s happening with our climate today and what we can expect for the future. In the news: tyrannosaur group, a chomped squid, horned crocs, and night dinosaurs. This episode, we’re joined by Dr. Rachel Lupien!
