The Heartland Institute, “the primary American organization pushing climate change skepticism,” has a new billboard campaign featuring Osama bin Laden, Ted Kaczynski, aka, the Unabomber, Charles Manson, and Fidel Castro, and the words, “I still believe in Global Warming. Do You?.” Heartland is suggesting that adherents to the science of climate change are mass murderers and political tyrants.

“These rogues and villains were chosen because they made public statements about how man-made global warming is a crisis and how mankind must take immediate and drastic actions to stop it,” the Heartland website states. They add that “what these murderers and madmen have said differs very little from what spokespersons for the United Nations, journalists for the ‘mainstream’ media, and liberal politicians say about global warming.”
