Vikings farmed southern Greenland 900 years ago during the Medieval Warm Period, but the climate is much too cold now to support farming.
Lisa J. Graumlich, who examines the ring patterns of foxtail pine trees and western junipers in the Sierra Nevada, has compiled a detailed record of the year-to-year variation in temperature and precipitation over the last thousand years.
She has seen in the North American trees the feathery but unmistakable signatures of the Medieval Warm Period, a era from 1100 to 1375 A.D. when, according to European writers of the time and other sources, the climate was so balmy that wine grapes flourished in Britain and the Vikings farmed the now-frozen expanse of Greenland
With only about six weeks left in the melt season, Greenland is still gaining ice.
Greenland is almost completely covered with bright white snow and ice.
Climate fraudsters now claim that there never was a Medieval Warm Period, because they are paid to lie about the climate in support of the White House political agenda.
