I think the earth just naturally goes through warming and cooling cycles. I well remember the new "ice age" fear mongers. But it is hot! I am an environmentalist by trade. We are doing much better in some areas. I don't know how much of the current warming is man-made. The "computer models" have been consistenly wrong about a lot of things. The evidence suggests that atmospheric CO2 levels are much higher than they were in earlier times. How much of an impact that really has on global warming is debatable. There is no doubt that anti-capitalists and Marxists have infected the debate with their own agenda. I would point out that the capitalist countries have a much better environmental record than the communist ones had. My rant over.
