““Venus is kept that way by a thick, dense atmosphere that’s full of carbon dioxide. It’s the greenhouse effect gone wild—runaway, as it is oft described. In fact, the models of climate change here on Earth were developed in part by scientists, James Hansen especially, who were studying the atmosphere of Venus. They observed that visible light passes the atmosphere, hits the surface, and then is reradiated as heat that is then trapped by carbon dioxide. This process has a big influence on whether or not a planet is habitable.””
