This report comes from Dr. Roy Spencer and the NoConsensus website.
Dr. Roy Spencer a well-known climatologist and global doom skeptic (not a climate change skeptic to my knowledge) posted this article on October 20th.
According to No Consensus, there are two key points you should know. First, Dr. Spencer was one of the main people involved in satellite temperature measurement and is currently the team leader for the top/only satellite-based microwave global temperature radiometers used by NASA.
Dr. Spencer compared all the climate models from the past 50 years and found that EVERY SINGLE MODEL overpredicted global warming.
The 36 models are those catalogued at the KNMI Climate Explorer website, using Tas (surface air temperature), one member per model, for the ssp245 radiative forcing scenario. (The website says there are 40 models, but I found that four of the models have double entries). The surface temperature observations come from NOAA/NCEI.
The official NOAA observations produce a 50-year summer temperature trend of +0.26 C/decade for the U.S., while the model trends range from +0.28 to +0.71 C/decade.

Back in the 1970’s it was Global Cooling and New Ice Age
I think that Dr. Spencer is a “Lukewarmist” .
He believes the GHG Theory but claims it is not threat.
Therefore, any of his comments and articles are false.
Spencer can’t come out of the skeptic closet as his contract to analyze the RSS satellite data with NASA would come to an end. At 20PPM, CO2 has saturated the atmosphere, meaning adding more CO2 won’t make a lick of difference.
Models are only as honest as the person who designs them and any model from Gore and DiCaprio is not good and the same for Greenpeace as well
Any real scientist will tell you that “All Models Are WRONG, Some Models are Useful” and we can all see the use to which these models have been put!
