New Study: 1900-2010 Global Warming So Uncertain Any Rate Or Magnitude Conclusion ‘Impossible’
By Kenneth Richard on 24. July 2023
“The compilation of land- and sea-surface [thermometer] uncertainty yield a 1900-2010 global air-temperature record anomaly of 0.86 ± 1.92°C (2 σ), which renders impossible any conclusion regarding the rate or magnitude of climate warming since 1850 or earlier.” – Dr. Patrick Frank (2023)
The global surface air temperature record is so contaminated by systematic error (due to solar irradiance, wind speed, albedo reflectance, thermometer physical inadequacies, drift…) that is impossible to distinguish the contaminated from the valid temperatures.
The built-in ± 1.92°C “range of ignorance” in estimating the global temperature changes since 1900 cannot be reduced by averaging, as the errors are clearly not randomly distributed, but instead strongly related to contaminating environmental factors.
A summarizing estimate of the global temperature change since 1900, including the range of ignorance due to error, indicates the 30-year trend was 1.82°C per century from 1971-2000, but 0.0°C per century during 1981-2010, and 1.23°C per century from 1911-1940.
