I vote that you're the stupidest twit I've ever had the displeasure to know.
The initial 280 ppm was what was keeping the Earth at the pre-Industrial revolution temperatures. The added 120 ppm is what caused the warming we've experienced and even with no more added, the further warming we'll see over the next century.
And you think it's evil! Now you're just silly!
Can we take that as a vote of agreement on "the stupidest twit" issue?
