The only reason the left is fixated on calling it climate change now is because around 15 years ago they realized that all the dire predictions they made in the late 90s hadn't happened even though C02 kept increasing. MMGW and MMCC, whichever you subscribe to, is just a ploy by governments to take more power and money from regular people.
If it's really that big a deal, when do you think we should we invade China?
