While there may be rock hard science that the globe is warming - that is not the same as PROVING that it is caused by CO2 emissions. There have been long cycles of heating and cooling before man ever left his cave.
Tell that to Only1choice____Freedom who thinks a Prius must now be bought. The article didn't say diddly about greenhouse gases.
From 800 a.d to about 1200 a.d the climate of the earth had to be quite a bit warmer for Greenland to have been settled and crops grown by the Vikings. Why didn't this tremendous warming result in millions of deaths around the world from rising ocean levels? Surely some historian would have recorded changes in water levels. I guess the world didn't end from the effects of this warming (/sarcasm).

It is not the same as PROVING that it is caused by CO2 emissions that are the result of human activity.
You already see them blaming the greenhouse gasses on methane from Siberian tundra. Man will be reduced to the trigger of the trigger in the greeny whacko's eye.
I also love how all the data shows that it hasn't been this warm in XX years. Which, of course, means that natural cycles have made it this warm before.
