I'd normally say *DUH?* but, many folks poopoo the idea that volcanoes and other Earthly emissions play a major role in Earth's past, present and future.

If they had a better knowledge of these effects, the misconception of man-made global warming would be farther from their minds.

It took the scientists 400 million years until the eve of the Copenhagen conference to find this out.

Volcanoes and other earthly emissions undoubtedly play a roll in the earth's mean temperature, but contrary to this author's tired old line, it's just not C02 that does it. Probably has more to do with lots of particulate matter being thrown way high into the atmosphere and reflecting solar radiation as opposed to "greenhouse gasses". Rising C02 concentrations have been shown over and over in ice core data to follow rising temperature, not the other way around.....
