On September 6, 2011, in an exclusive piece for Mother Jones, investigative journalist Brad Friedman posted audio from a secretive June 2011 conference in Colorado hosted by climate-change-denying libertarian billionaires Charles and David Koch. In one clip, Charles Koch compared President Obama to Saddam Hussein. That evening, Friedman discussed the conference on MSNBC’s “The Ed Show.”

On September 6, 2012, in his speech at the Democratic National Convention, President Obama responded to Republican presidential candidate Mitt Romney’s infamous joke about climate change, declaring:

“And yes, my plan will continue to reduce the carbon pollution that is heating our planet – because climate change is not a hoax. More droughts and floods and wildfires are not a joke. They’re a threat to our children’s future. And in this election, you can do something about it.”
