I have written a lot before about how AGW (or climate change) is just the means by which the UN was trying to establish a world government. Maurice Strong, the Canadian billionaire socialist started the UN IPCC with the expressed intent of "destroying western civilization." The UN doesn't care whether or not the AGW hypothesis is correct, it is just the means by which the UN would like to achieve its true objective of establishing a world government, one with taxing authority. Here is a good discussion of this matter.
