I don't buy it at all -- all roads lead to a "carbon credit" economic bubble. If you want to cut carbon emissions, cut the US military in half, reduce commercial air travel. Follow the money. Favorite "global warming" joke: A mouse is fucking an elephant as it marches through the jungle. The elephant bangs its head on a branch and says "Ow!". The mouse says "TAKE IT ALL, BITCH!" Mankind couldn't change the climate if it tried. It's all bullshit, and it all revolves around MONEY and control.
