And all this crap about CO2? CO2 is one of a handful of gasses that contributes less than 3% to the so called green house effect. Water vapor contributes over 96%. When do the environmentalists ever bother to mention that? If you removed 100% of all CO2 from the atmosphere, other than the extermination of all plant life on earth, the net effect on the global temperature would be about 2 degrees. CO2 is not a leading indicator of climate change, it is a trailing indicator. If you look at charts plotting rise in CO2 and rise in temperature in ice cores, tree ring growths, and sediment samples, you see that as temperatures rise, more CO2 is released from rotting vegetation, from ice flows, and methane ice. Correlation does not imply causation. Something they obviously don't teach in schools anymore.
