Activists confront oil billionaire David Koch and serve him with a notice of his climate crimes at the Americans for Prosperity convention in Washington DC on Nov 4, 2011. Koch is asked how much money Koch Industries stands to make if the Keystone XL tar sands pipeline is approved, and if the recent publication of the Berkeley Earth Surface Temperature study, which Koch helped fund, has changed his views on global warming.
