RE: Apparently, Mann and his colleagues never tested their program with the standard Monte Carlo approach [!!!]
That's a big boo boo. What sort of real scientist would fail to do this?
RE: Did medieval global warming take place?
Well, we know this much. Vinyards in the UK and a place in Bavaria called "Valley of the Limes." Sure it's only circumstantial evidence, but it is hard to explain away with the Medieval Warming.

You win the prize! Its not like these are obscure historical facts, vinyards in England suggests that the "science" is all wet. I also seem to remember viking accounts of the northlands being more green than they are today with the archeology backing the stories up.
I'm sure another FReeper can confirm this.
Never heard that. I'll now use it in my anti-global warming arguments.
In Jared Diamond's "Guns, Germs, and Steel" he talks about how the plant was so warm and humid several 10,000 years ago that the Sahara desert was a grass land. Until the global warming "scientist" can explain why, I won't give them the time of day. Heck I grew up in the 70's when the new ice age was approaching.
This scare tactic is straight out of Machiavelli's "The Prince"
In that particular instance, Limes refer to a system of old Roman fortifications and not citrus fruit.
I believe they ran for some 500 miles along the Rhine and the Danube.
