The many poster here that wish to hand wave away Global warming have often claimed volcanos produce more CO2 than humans. I asked for a link documenting that not too long ago because frankly I felt there was no way that was true given the scientific credibility GW has in most scientificly literate circles. Well guess what, that is pure wishful thinking on the order typical of psuedoscience rather than science.

volcanos 10,000 times less CO2 Than humans

"There is no doubt that volcanic eruptions add CO2 to the atmosphere, but compared to the quantity produced by human activities, their impact is virtually trivial: volcanic eruptions produce about 110 million tons of CO2 each year, whereas human activities contribute almost 10,000 times that quantity. "

Another interesting link covers the data often mentioned on increasing solar luminosity.
Sun's brightness increased by 0.036 percent from 1986 to 1996

Biological data indicating there are real effects from global warming are indicated at Life on Earth Is Feeling the Heat

It is truly amazing how different the real data is from the "facts" publicized by the likes of Rush Limbaugh.
