global warming is significantly man man made

global warming is significantly man man made here is a general website that debunks anti man made global warming folks, claim by claim http://www.skepticalscience.com... here is proof that carbon dioxide has nearly doubled and increased exponentially since the industrial revolution http://en.wikipedia.org... here is a similar graph that shows temperature following a similar fate http://en.wikipedia.org... here are websites that tie together co2 and temperature, and debunks any claims about why co2 and temperature carbon are not always tightly correlated http://www.skepticalscience.com... http://www.skepticalscience.com... here is a graph showing the thickness of polar caps melting exponentially http://en.wikipedia.org... here is a scientific article that refers to the ice caps being doomed http://www.scientificamerican.com... ======================= warming not caused by volcanoes and the Sun cycles -------------- 'The volcano theorists can't even keep their stories straight. In his book, Limbaugh claims that the 1991 Pinatubo eruption put 1000 times as much chlorine into the atmosphere as industry has ever produced through CFCs; yet on Nightline, Pinatubo is alleged to have produced 570 times the equivalent of one year's worth of CFCs. Both can't be right. It turns out neither are. The figure 570 apparently derives from Ray's book--but she said it was Mount Augustine, an Alaskan volcano that erupted in 1976, that put out 570 times as much chlorine as one year's worth of CFCs. Ray's source is a 1980 Science magazine article--but that piece was actually talking about the chlorine produced by a gigantic eruption that occurred 700,000 years ago in California (Science, 6/11/93).' '--------- i'd also add, that hte common sense answer to me is... consider all the smoke stacks out there. consider all the pollution, places like LA. i'd bet california itself is like a volcano very short period in intervals. doesn't this make the most sense, considering how little and how infrequent volcanoes erupt? ---------- scientific article saying the sun is only accounting for a third of our warming ------------- QUOTE With respect to global warming, though solar activity has been at relatively high levels during the recent period, the fact that solar activity has been near constant during the last 30 years precludes solar variability from playing a large role in recent warming. It is estimated that the residual effects of the prolonged high solar activity account for between 18 and 36% of warming from 1950 to 1999 ^ Stott, Peter A.; Gareth S. Jones and John F. B. Mitchell (15 December 2003). "Do Models Underestimate the Solar Contribution to Recent Climate Change". Journal of Climate 16: 4079-4093.
