From Dr. Roy Spencer’s Global Warming Blog
As seen in the accompanying plot, 50-year (1973-2022) summer (June/July/August) temperature trends for the contiguous 48 U.S. states from 36 CMIP-6 climate model experiments average nearly twice the warming rate as observed by the NOAA climate division dataset.
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.
The importance of this finding should be obvious: Given that U.S. energy policy depends upon the predictions from these models, their tendency to produce too much warming (and likely also warming-associated climate change) should be factored into energy policy planning. I doubt that it is, given the climate change exaggerations routinely promoted by environment groups, anti-oil advocates, the media, politicians, and most government agencies.

Almost half of the all time hottest temperatures in the 50 US states were set in the 1930’s.

RADIATIVE FORCING BY CO2 OBSERVED AT TOP OF ATMOSPHERE FROM 2002-2019
https://arxiv.org/pdf/1911.10605.pdf
“The IPCC Fifth Assessment Report predicted 0.5080.102 Wm−2RF resulting from this CO2 increase, 42% more forcing than actually observed. The lack of quantitative long-term global OLR studies may be permitting inaccu-racies to persist in general circulation model forecasts of the effects of rising CO2 or other greenhouse gasses.”
Profound: Smoking Guns!! Proof with accurate 2 decade long measurement of the actual amount of radiative forcing caused by CO2 of 1 irrefutable reason for WHY global climate models continue to be too warm. Climate emergency is really about social justice and brainwashing people. Even MORE confirmation that climate models overstate atmospheric warming. Models clearly too warm yet incredibly programmed to get even HOTTER! August 2020 https://www.marketforum.com/forum/topic/57636/
