Colbert argues for end-of-the-world sex. Bill McKibben argues that chemistry and physics don't haggle. In the end, Colbert plugs the date: October 24th, the 350 International Day of Action on Climate Change, planned for more than 1,500 locations, including the Pyramids, the Taj Mahal, and the Great Barrier Reef, where people will unite in a common call to lower carbon levels to 350 parts per million.
McKibben wrote persuasively about the need for this in last November's MoJo. How CO2 levels have already reached 390 ppm. How we need deeper and more rapid cuts than politicians have so far embraced. October 24th is a way to join voices before the global treaty talks in Copenhagen in December.
