IPCC Climate Models Grossly Exaggerate 'Global Warming'
Several recently published studies have provided methodological objections to alarmist IPCC global climate models that predict catastrophic global warming will result from anthropogenic CO2 atmospheric concentrations from burning hydrocarbon fuels. These studies indicate that a more accurate reading of the earth’s surface temperatures suggests global climate warming over the next few decades will be moderate. The studies further indicate that more precise surface temperature readings would seriously dampen the hysterical mass media demand for radical public policies requiring radical decarbonization to achieve Net Zero Emissions (NZE) as quickly as possible.
In November 2022, meteorologist Roy Spencer, Ph.D., a Principal Research Scientist at the University of Alabama in Huntsville, published a ground-breaking study demonstrating that 36 climate models used to guide national policy may have exaggerated “global warming” over the last 50 years by as much as 50 percent. Specifically, Dr. Spencer utilized “a relatively new global dataset of urbanization changes over the previous 40-year period, 1975-2014, based on Landsat data to determine the average effect urbanization has had on surface temperatures.”
Spencer devised a methodology “to compute the magnitude of the Urban Heat Island (UHI) effect on temperatures using the example of summertime early morning 09 UTC (early morning) Integrated Surface Database (ISD) hourly data (mostly from airports) over the period 1973-2022.” (“UTC” stands for Universal Time Coordinated, formally known as Greenwich Mean Time (GMT).) His goal was to compare “urbanization differences to temperature differences from closely spaced weather stations.”
Using this methodology, Spencer’s results were astounding: “The results for the U.S. lead to a 50-year warming trend 50 percent less than that from the official National Oceanic and Atmospheric Administration (NOAA) homogenized surface temperature dataset.” (Emphasis added.)
