Why should we spend the VAST amounts of money required to protect ourselves on something that MAY or MAY NOT happen in the next 100 years?
While I do agree that global warming may or may not be a cycle or trend, how hard is it to cut down on using fossil fuels just to improve the quality of air we breathe? No, the air isn't unbreathable. And we're lucky not to be stuck in a metropolis like Los Angeles or Toronto with huge smog clouds and stifling tempertatures. But it could be a hell of a lot better.
