UN IPCC Lead Author’s Research Demonstrates UN IPCC is Wrong

New research paper by a former UN IPCC lead author: 8000 years of ice core data were examined. From the abstract at the link below: “The average standard deviation of temperature was 0.98 ± 0.27 °C. This suggests that while some portion of the temperature change observed in the 20th century was probably caused by greenhouse gases, there is a strong likelihood that the major portion was due to natural variations.”

UN IPCC’s estimate of man-made warming plus natural warming is 0.85 degrees in total, an amount of warming which is less than the standard deviation 0.98 degrees for the last 8,000 years.

In other words, this amount of warming is not significant within the context of the Earth’s climate history.
