New York Times 1992 – MWP And LIA Were Global

In 1992, the New York Times said there was no indication of global warming and that the MWP and LIA were global.

Warming? Tree Rings Say Not Yet

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. A Crucial Question

“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?”

This was consistent with the 1990 IPCC Report.

    Don’t tell Michael Mann. It will destroy his life’s work…

    There are links to the locations of over 1200 papers covering the MWP here

    The results of the papers are summarised, typical one below, which is in the minority and doesn’t show the The MWP and is from the Southern Hemisphere

    METHODS: Peat accumulation rate as temperature proxy

    RESULTS: Cold MCA interpreted by authors based on low peat accumulation rate during MCA. From abstract: “The period from 1350 to 450 calibrated years before present (cal yr BP) at the north-facing peatbank had low accumulation (0.25 mm yr−1, 36 g OM m−2 yr−1), which we interpret as a period of low temperature and increased snow cover. Microclimate differences were amplified by this regional climate cooling, causing the delayed peat initiation on non-equator-facing slopes.” Note, however, that the MCA itself is not age-dated and may in fact rather represent a hiatus or erosional preservation gap. Other studies from the Anvers Island region suggest a warm MCA and possible erosion by post-MCA glaciers.

    The only way they can get away with this mendacious scam is if the majority of the scientific community is woke lift, just like the educational system. They are surrounded and protected by their own kind. Add in the politicians and nothing is left to stop the suicidal self-destruction.
