A Tale of Two Scientific Consensuses

Environmentalists constantly reference the scientific consensus that human activity is changing the global climate. "You have the strongest consensus we have seen in the science community about global climate change since the conclusion that tobacco caused lung cancer," asserts Union of Concerned Scientists (UCS) president Kevin Knobloch. Greenpeace also argues, "There is, in fact, a broad and overwhelming scientific consensus that climate change is occurring, is caused in large part by human activities." And Friends of the Earth has gone after Exxon Mobil because it "has repeatedly attempted to undermine the scientific consensus on climate change and actively resisted attempts to limit carbon dioxide emissions through law."
