We find evidence of a widespread medieval warming culminating in the 10–11th centuries, followed by a gradual cooling into the 17th century, succeeded by a dramatic warming from the 18th century that accelerated into the 20th century. Our result also indicates that the warmth in the 10th and 11th centuries was as uniform as is the current 20th century warming.

And this meeting was set up to mitigate the effects of the findings. Here are the attendees. Phil, Mike and the whole gang were there to get their marching orders. Apparently, the meme will be, “Nothing to see here, move along.”

MWP….Many Wankers Present?
Let me get this right. You guys are hoping that there is a MWP?
Hey Don! You may want to stop quoting Skepticalscience (which is niether) after reading this…
Brendon now you are really grasping at straws. First the theory, yes theory of man made global warming hasn’t been proven to be fact. What past rises and drops in global temperature show is that insignificant man doesn’t completely understand how the climate works. Until we do there is no way to prove that man is having any effect on the climate.
What I see when I look at the site you linked to is a bunch of inaccurate graphs. Why? No orbital, cloud or oceanic current changes are accounted for. And it appears to me that the logarithmic effect of CO2 has likely been substituted for a linear effect.
When you can offer evidence that we completely understand all the natural influences on the climate and then accurately forecast long term results and then test those results using accurate real world data, then can we begin to know if man has any effect on the climate.
As the computer models in use today have failed miserably in providing accurate forecasts we have a long way to go.

The abstract for Mann’s paper sounds like it was a work in progress (not ready for prime time).
Amazing gall this UNscientific crowd is displaying. At the very same time they are being accused of cooking the books, they run to the kitchen and put enough cooks (crooks) on the job to (purposely) ruin the broth once again. M(orons) W(ith) P(hd’s).
