Jim, I saw that show. As you say it was merely pointing out another phenomenon, global dimming, which although theorized, was difficult to confirm until the unfortunate events of 9/11. I did not see where scientists were trying to deny the existence of global dimming. One interesting conclusion was that if we try to reduce global dimming, we may, in fact increase global warming. What to do, what to do.
That global warming exists, there is no doubt. But whether the cause is human consumption of fossil fuels or a natural cycle, has not been adequately answered, in my opinion. Glaciers formed and covered most of North America and receeded without any human intervention several times in the last millinum. We need to understand that fact in relation to what is happening now with human intervention. The answer is not yet clear to me.
Perhaps the cycle of volcanic activity was responsible for the formation and recession of the glaciers. Is the volcano of human consumption equivalent to that of mother earth? Dunno.
Regardless of whether we are causing global warming or whether it is a natural occurrence, we should do everything possible to reduce our reliance on fossil fuels, if for no other reasons than being able to breathe clean air and to insure a more economically stable source of energy for the world.
