THE HOCKEY SCHTICK: New paper shows W Greenland glacier retreat has decelerated about 50% over past 70 years
A new paper published in The Cryosphere examines historical length changes of glaciers in W Greenland from 1800-2010 and finds "the average rate of retreat was largest in the first half of the 20th century." Data from the paper shows the average rate of retreat peaked at 25 meters per year during the 1930's and has decelerated to about half that rate over the past 70 years. Note glaciers have been generally retreating for 20,000 years since the peak of the last major ice age, and since the end of the Little Ice Age in 1850.
THE HOCKEY SCHTICK: New paper finds Arizona droughts were less frequent and less extreme during 20th century
A new paper published in Climatic Change reconstructs droughts in NE Arizona over the past 400 years and finds the 20th century had "fewer multiyear [severe droughts] than any other century" and that "Perhaps of greatest relevance, this study suggests that severe and sustained episodes of dual-season drought, which are largely missing from the instrumental period, have occurred multiple times in the past (e.g., 1660s, 1740s, 1890s)." The paper adds to multiple others demonstrating that global warming does not increase the frequency or severity of droughts, floods, cyclones, or extreme weather.
THE HOCKEY SCHTICK: New paper finds Greenland was 2–3°C warmer than today 4000 years ago
A paper published today in Quaternary Science Reviews finds west Greenland was "2–3°C warmer than today" from 6,000 to 4,000 years ago and that "summer temperatures were warmer than present by at least 7,100 years ago." According to the authors, "the local Greenland Ice Sheet margin was most retracted behind its present position between 6,000 and 5,000 years ago." The paper corroborates ice core data from central Greenland indicating that Greenland was significantly warmer than the present several times over the past 8,000 years despite "safe" levels of CO2. This paper and many others demonstrate that alarmist claims of a 2°C "tipping point" for the Greenland ice sheet are nonsense.
