It seems just yesterday that Al Gore directed our attention to Greenland, for which we should all be grateful. Greenland artifacts of Viking habitation demonstrate that the Medieval Warm Period was, indeed, warmer than the present.
However, Al Gore and his Acolytes are nothing if not history challenged. To them "unprecedented" warming means the end of the inconvenient cooling in 1975. For awhile they tried to say that present warming was the most in the past 1,000 years, but then Mann's "hockey stick" was shattered and they had to concede the Medieval Warm Period (800 to 1350 AD, well within the past 1,000 years).
Then it was unprecented warming for the past 400 years, which conveniently begins during the Little Ice Age. There sure wasn't much warming then.
Unfortunately for Al, science marches on and recent climate records for Greenland show that it was warmer, and got warmer faster, in the 1930's than our current period. (Click here for the report)
This chart of Greenland climate change for the past 170 years show that the 1930's warming was greater and faster than now.
What's a warming alarmist to do?
