I'll do a Google and a Bing and see what I can come up with.

Professor Ian Plimer:

"We cannot stop carbon emissions because most of them come from volcanoes," he said. "It is a normal element cycled around in the earth and my science, which is looking back in time, is saying we have had a planet that has been a green, warm wet planet 80 per cent of the time. We have had huge climate change in the past and to think the very slight variations we measure today are the result of our life - we really have to put ice blocks in our drinks."

Then there's this opposing info:

the Bush administration has now acknowledged the obvious:

Burning fossil fuels in power plants and automobiles is most likely responsible for global warming, according to a Bush administration report that confirms climate risks already accepted by most of the world's scientists. Carbon dioxide, the byproduct of burning coal and oil, has contributed most to warming in the last century, the U.S. Climate Change Science Program and the White House National Science and Technology Council reported today. The assessment from President George W. Bush's top science advisers is the strongest endorsement yet of a global scientific consensus on the causes of climate change, said Jay Gulledge, senior scientist at the Pew Center on Global Climate Change, a nonprofit research group.
