The IPCC’s Latest PAGES 2k (2019) Temperature Hockey Stick Is Contradicted By . . . PAGES 2k (2015)
By Kenneth Richard on 16. August 2021
The IPCC’s latest report uses a hockey stick-shaped reconstruction of global temperatures that wholly contradicts previous records produced by the same PAGES 2k and Oceans 2k consortiums from 4 years earlier.
In 2015, the PAGES 2k Consortium published an updated (“corrected”) 0-2000 AD global reconstruction that showed a large portion of the 1st millennium was globally as warm or warmer than the last 30 years of the 20th century.
The authors added a red-hot near-vertical line to to the 30-year bins to emphasize modern warmth even as they acknowledged the late 300s CE, as well as the 1941-1970 period, were warmer (Arctic) than 1971-2000.
As the pink-blue graph on the bottom of the image below shows (coloration/annotation added, red line removed), the anomalous temperatures (blue) in the last 2000 years occurred during the globally-coherent Little Ice Age. Late 20th century warmth was only a partial return to the 1st millennium climate “normal” (pink).
