Mark, what about Bjorn Lomborg's critical analysis of the inefficiencies of "climate change" puffery? Billions wasted on the short-sighted ignorance of politicians like McGuinty, Butts, and Wynne - with nothing to show for it. Solar and wind are terribly inefficient on an industrial scale. Smug leftwing career activists fly around the world for a living and think buying carbon offsets makes any difference other than making them sleep better at night. Why do climate change activists ignore population growth in Africa and the Middle East? Perhaps because the UN's pious leaders (OIC for example) are hostile to the point of violence against contraception, but we can't talk about that, it's not politically correct. What about the positive externalities of "global warming" to Canada? Longer growing seasons, higher industrial productivity... crickets from activists, it's all doomsday apocalypse and negative hyperbole.
