You display your absolute complete ignorance with this comment. The records of the "Medieval Warming Trend" are NOT from "Middle Age Records"--they are based on scientific measurements from ice cores, pollen samples from sediments, archealogical data (physical measurements on human remains from the period), and the like. These records are far more "science-based" (i.e. based on MEASUREMENTS) than the MODEL-BASED global warming theories.
"Your extrapolation to assume that warming will have positive consequences for the entire planet are oh so naive."
Oh, certain (probably small) areas of the planet will undoubtedly have some negative consequences. So did the Medieval Warm Period (droughts in the desert Southwest, for instance). But, for the most part, the scientific historical record says that the positive effects outweighed the negative effects in geographical extent.
"Sorry pal, you are placing a wager that is way to high for my blood."
So you support the establishment of a global socialist bureaucratic order to "prevent global warming"?? That is what it is really all about, you know.
Yes, that is what the global warming crowd is about. It should also be noted that some 30 years ago the threat was global cooling.
As to your statements about the cooling, they are true. We know there was a fairly large population in Greenland that was farming and living as in warmer climes. The evidence is undeniable.
