But it's not. It's actually trending cooler over the past decade. It's just the SE U.S. that is not experiencing cooling during the recent winters that makes us think the world is warming. We have more humidity and rainfall. Climate is changing, but it's not driven by man's activities. AGW is a scam to remove individual rights from the few remaining "free" countries.
Many places in the northern hemisphere (Japan and China) have experienced record cold and snow. The southern hemisphere has been consistently below normal in many places. You have to look at the entire globe, not just your backyard or even the U.S.
We need to utilize the least expensive forms of energy in the manner that is most beneficial to humans. If it's natural gas, burn it, but do it cleanly. If it's coal, same thing, but do it as cleanly as possible (bio-toxicity is the REAL threat).
