I don't see it out my window. Or feel it. When I've gone outside this year, I have usually marveled at how mild this year is .... and I have experience with Houston area weather from 1974 on.

Back to Mann, he used proxies (mostly tree rings) to estimate temperatures back deep into the past. He assumed that temperature is the primary factor that affected tree growth in the past, not rainfall, not local effects of tree crowding, shadowing, etc. Since his proxy determined temperatures showed the temperatures falling dramatically after 1960, he cut that part of his graph off and substituted actual temperatures. If he'd been ethical he would have questioned the validity of the proxy determined temperature all together ... after all, if the proxies didn't work after 1960, who's to say they worked centuries ago?

Mann, James Hansen and most other big name climatologists see themselves as prophets and world saviors. They are activists in a great cause as they see it.
