On 1/18/23 there was an interesting article in American Thinker entitled “IPCC Climate Models Grossly Exaggerate ‘Global Warming,’ which begins:
“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.
Okay I thought, another anti-global warming article … Ho-hum! However, while reading through this piece, what caught my attention was that three different scientists with different backgrounds, from two different countries were saying basically the same thing.
First, 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
Spencer’s research shows that increased urbanization, not increased CO2, is responsible for exaggerating the temperature measurements recorded in the NOAA homogenized surface temperature dataset. In other words, Spencer’s point is that observed increases in temperature result from the greater heat urbanization generates, not from increased CO2 concentrations generated in the atmosphere by burning hydrocarbon fuels.
Second, August 2022, meteorologist Anthony Watts found that 96 percent of the temperature stations in the United States used to measure global warming and climate change did not “meet what the National Oceanic and Atmospheric Administration (NOAA) considers to be ‘acceptable,’ uncorrupted placement.”
To reach this conclusion, Watts “compiled satellite and in-person visits to NOAA weather stations” that provide “official” temperature data. His visits revealed that these stations are corrupted by localized effects of urbanization—producing heat-bias because of their close proximity to asphalt, machinery, and other heat-producing, heat-trapping, or heat-accentuating objects.”
There’s more … In August 2022, Nicola Scafetta, at the Department of Earth Sciences, Environment and Georesources, University of Naples, Italy stressed that if the UAH (UAH satellite developed at the University of Alabama, Huntsville) MSU (Microwave Sounding Unit radiation measurement) record is accurate, “surface warming from 1980 to 2021 may have been around 0.40°C (or less), that is up to about 30 percent less than what is reported by the surface-based temperature models.” Scafetta concluded that correcting IPCC over-estimating global surface temperatures suggests “the projected global climate warming over the next few decades could be moderate and probably not particularly alarming.”
So here we have three different scientists basically saying that the surface temperature measurements upon which global warming is based are exaggerated, and very possibly due to urbanization.
