As the U.S. is accused of blocking progress here at COP18 talks in Doha, a new report says the Koch brothers may be the biggest force behind the climate stalemate. The Koch brothers run oil refineries and control thousands of miles of pipeline, giving them a massive personal stake in the fossil fuel industry. But researchers say they ve also funneled tens of millions of dollars into climate denial science, lobbying and other efforts to derail policy that could lessen the impact of global warming.

Hedge Fund money teams up with Koch and BB&T to buy the minds of America's students and professors.

David H. Koch is many things -- billionaire, Tea Party funder, general party thrower. But there's one totally unexpected position Koch holds: trustee at WGBH Boston, PBS's largest affiliate and producer. This is curious in itself, particularly considering many of Koch's cronies in Congress want to totally defund PBS.

The Koch family, America's biggest financial backers of the Tea Party, would not be the billionaires they are today were it not for the godless empire of the USSR.
