   Mann should have used tree rings from labradorean.

   An Andean ice-core record of a Middle Holocene mega-droughtin North Africa and Asia

   A large dust peak, dated ~4500 years ago, is contemporaneous with a widespread and prolonged drought that apparently extended from North Africa to eastern China, evidence of which occurs in historical, archeological and paleoclimatic records. This event may have been associated with several centuries of weak Asian/Indian/African monsoons, possibly linked with a protracted cooling in the North Atlantic…..

   Climate variability during the present interglacial, the Holocene, has been rather smooth in comparison with the last glacial. Nevertheless, there were some rather abrupt climate changes. One of these changes, the desertification of the Saharan and Arabian region some 4–6 thousand years ago,….

   There was a time 5 to 10 years ago when Mann basked in the accolades of leading a movement that was all the rage, and received endless kudos for his hockey stick. Now Mann is under attack for the hockey stick which has been shown to be a bullshit fabrication, and global warming climate change is no longer the cool or in thing, and one of many reasons for that is that the debunked hockey stick was an essential part of the AGW scam.
   Tom Nelson shows a picture of a pitiful looking gathering and says: What a warmist scientist conclave looks like during the dying days of the global warming hoax. Can we see Mann (balding) in the picture (see link) near the middle of third row from the back? I don’t know, it seems that person’s girth is not anywhere near enough to be Mann: http://tomnelson.blogspot.com/2013/06/links_6712.html

     Lots of professors in academia know the climate models are bogus yet still defend it. Holding back the dam of junk science is now a priority.

   Strange how half of Wisconsin and half of Alaska escaped glaciation.

       In Wisconsin, I’m sure the warming was caused by paleo dairy farmers’ cows, and Alaska was warmed by too much ice in Illinois.

         I read Richard’s explanation and found it informative, and educational. But I like yours better! 😆

       In the case of Alaska, most of those white areas were probably either underwater (and thus covered by permanent sea ice) or subject to alpine glaciers, which would not be indicated because are a distinct phenomenon from continental glaciers.

       In the case of Wisconsin I suspect that elevation is the strongest factor, i.e. an area of higher elevation causing the continental ice to slide down into lower areas and stay there; but it also occurs to me that this is far from an exact science, and it may be that they only include areas for which they had credible geological evidence of glaciation, which would obviously tend to exclude a lot of area that only received mild glaciation for a short time.

       It would be interesting to see the paper that went with this map.

     The area in Wisconsin is the Wisconsin Dells. This area contains unique rock formations that could not have survived under a glacial ice sheet. It is known not to have been covered, not only because of the rock formations, but because there is no glacial drift found there. It is refered to as a “Driftless Area”.

       Nice to know the Dells won’t be rubbed out in the next glaciation. 🙂
