Geologist: 'I cannot find evidence that CO2 has been one of the major drivers of climate.'

Global Warming Allegedly Kills Wyoming Forests

...a geologist in Cody says dramatic climate shifts have occurred many times throughout earth's history. Leighton Steward said after much study, "I cannot find evidence that CO2 has been one of the major drivers of climate."

Steward has written a book on his theory, that throughout the eons, CO2 is caused by global warming, and is not the cause of it. He says scientists from several countries have studied ancient ice cores, and found, "That temperatures changed, and several hundred years later, the CO2 levels changed."
