One's denial  or acceptanace of man-made climate change science should not be effected by the actions of high-energy using environmentalists. Judge the science on its own value.  High-energy living is extremely atttractive for those who have it and, ominiously, for a world that dreams of the lifestyle. I accept man-made climate change and use airplanes, cars and all the rest of it. I know my individual actions have little effect without government legislation so why would I give up the high life since I can afford it? Let's admit that high-energy living is extremely attractive even though the consequences are not.
