PERRY: On global warming, “The science is not settled on this. The idea that we would put Americans’ economy at jeopardy based on scientific theory that’s not settled yet, to me, is just, is nonsense. … Find out what the science truly is before you start putting the American economy in jeopardy.”

THE FACTS: The scientific consensus on climate change is about as settled as any major scientific issue can be. Perry’s opinion runs counter to the view of an overwhelming majority of scientists that pollution released from the burning of fossil fuels is heating up the planet. The National Academy of Sciences, in an investigation requested by Congress, concluded last year: “Climate change is occurring, is very likely caused primarily by human activities, and poses significant risks to humans and the environment.”
