Climate change is a much older subject than is commonly assumed. As early as 1750, Enlightenment thinkers such as David Hume and Thomas Jefferson analyzed and wrote about the role that human activity played in climate change. French scientist, Joseph Fourier discovered the greenhouse effect in the 1820s. So, the study of climate change did not come from a bunch of hippies in the 1970s! Dr. Andrew Ramey from Carnegie Mellon University joins us to explain the early history of climate change research, and we dispel a lot of climate change myths along the way!
