The issue is not whether the earth is in a warming period or cooling period.
The issue is is humanity causing the earth to warm to such a degree that we need to totally alter our economic systems?
Is it even a bad thing that the globe is warming?

Everything I have read shows that if we act now and institute methods to stop, or reverse CO2 emissions, it will have negligible impact, at best.

I still am not convinced in anthropomorphic global warming.
