If I said human activity doesn't affect the stock market -- it just operates on cycles. It goes up for awhile, then it goes down for awhile, you'd rightfully laugh at me. But that is exactly what you are doing about AGW.

Yes, the climate has changed in the past. But that doesn't mean the driver of those historical changes is driving the current change. People have always died, but that doesn't mean we shouldn't require safety devices in automobiles. Second, "cycles" is just way too blithe of a summary, as if there was a clockwork mechanism driving things. The gaps between the ups and downs is irregular.

I'm 100.00% sure climatologists are well aware of it and it has been modeled and found unable to explain the trends we are seeing.
