Greenpeace has issued a report that seems to provide a thorough reality check on the background of the climate change denial propaganda in the US: "Koch Industries: Secretly Funding the Climate Denial Machine". They also have an interesting interactive graphic that allows you to check out some details directly.
Amazing that Koch Industries, the company that Greenpeace exposes as a major sponsor of the climate sceptics, is little known in the public although, as they claim on their webpage, it is one of the largest private companies of the world. Obviously they know about doing things secretely. The company has issued a statement on the report, however.
This reminds of the Exxon Report by the Union of Concerned Scientists, on which I have blogged before. Apparently, Koch Industries easily out-spent Exxon Mobil in the area of political sponsoring. Interesting indeed.
Other blogs such as Climate Progress or ClimateScienceWatch have more details on the story. I wish I had time to study and cover this report in more detail.
