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.
