For decades, Exxon has publicly questioned the science of global warming, contradicting internal findings by the company’s own scientists. Recent exposés by InsideClimate News and the Los Angeles Times reveal that Exxon concealed for decades its own conclusions that fossil fuels cause global warming, alter the climate and melt the Arctic. Exxon’s climate deception is now sparking calls for a federal probe similar to that which yielded a racketeering conviction of Big Tobacco for hiding the dangers of smoking. We are joined by Rep. Ted Lieu (D-California), who is calling for a Justice Department investigation of Exxon, as well as 350.org co-founder Bill McKibben, who was just arrested for a one-man protest shutting down his local Exxon gas station. "It’s difficult to think of a company that could have set back humanity for decades, and perhaps permanently," Rep. Lieu says. "But that’s what happened here."
