Twenty five years ago, the IPCC reported a strong Medieval Warm Period and Little Ice Age.
In 1992, the New York Times reported that the Medieval Warm Period and Little Ice Age were “global climate phenomena, not regional temperature variations”
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; and the Little Ice Age, a stretch of abnormally frigid weather lasting roughly from 1450 to 1850.
“We can now see that these were global climate phenomena, not regional temperature variations,” she said. “The question is, how did we get those warmer temperatures during pre-industrial times, and what can we learn from those conditions about what is going on today?”
Climate criminals knew that their scam was destroyed by the existence of the MWP and LIA, so they made it disappear 15 years ago, claimed they occurred only in Central England, and invented the hockey stick.
I received an astonishing email from a major researcher in the area of climate change. He said, “We have to get rid of the Medieval Warm Period.”
