“While the Koch brothers admit to not being experts on the matter, these billionaire oil tycoons are certainly experts at contributing to climate change. That’s what they do very well. They are one of the main causes of this. Not a cause, one of the main causes.”

…So does one-third of 1 percent in the United States make a company “the champions” and “one of the main causes” of global climate change? Perhaps that’s a judgment call, but the Koch brothers’ contribution shrinks even further when seen in global context — to about 6/1,000th of a percent. That’s because there are many companies overseas that are far bigger polluters.

Verdict: three Pinocchios
