Warming has occurred. As has cooling. You've been duped by the AGW scientists into believing that the end of the Little Ice Age is the earth's natural temperature. It's not, and it fluctuates much more than those scientists would like you to believe. The 'inconvenient truth' about the earth's average temperature is that almost everyone on the earth would benefit greatly if the earth's average temperature would rise ~2 degrees C from its current temperature. Unfortunately, that's extremely unlikely due to the sun's solar cycles.
The burden of proof is on you to show why an increase of one of earth's most important ghg's by 40% would NOT result in the warming we are seeing. It is absurd to think it wouldn't.
What warming? The warming from adjusting temperatures? Remove those adjustments and the earth's temperature has been static for two decades. But two decades is not long enough to state that it's a trend, nor is even two centuries. Too short a period of time. But you wouldn't understand that.
Yes, and the adjustments are also why the ice is melting everywhere. Are you for real? Did you do what I told you and ask for the money back that you completely wasted on your college education? You can then use that money to pay for a psychiatrist. It's obvious that you have a chemical imbalance.
