Have you stopped driving your car? Stopped flying around the country?

I gotta say since it's been changing for millions of years, I have my doubts.
Should we be doing everything reasonable to develop and use alternative energy, ones that don't produce c02 as a by product, absolutely.
But, even if folks gave up and changed their life styles, I'm not so sure that would stop climate change, might slow it down ...maybe.

Do you think we'd be better off with a new ice age?
