Uhh no it isn't. It's based on computer models. Satellite data show no global warming. The temperature curves that purport to show global warming have been doctored only to show those segments that fit the (false) hypothesis.

BTW, there's nothing wrong with computer models per se: if someone ever makes a computer model based on the only last 150 years of data and general physical principles that correctly retrodicts the little ice age, the subsequent warming, and the warm period before the little ice age, I'll be interested in seeing what it predicts.
