We continue our discussion with Dr. Andrew Ramey from Carnegie Mellon University about the long history of climate change science. The study of climate change grew rapidly in the 20th century, almost as quickly as climate change itself started to affect the earth dramatically. By the 1970s, however, countervailing forces (including the fossil fuel industry) moved into the scientific debate and started well-funded political campaigns to stop any effective governmental action to reduce climate change. Just at the time when the scientific evidence was undeniable and compelling, politics got in the way.
