Temperature update for Oct 2023 is 1.1C

A little late but here is my update on the global temperatures for October 2023, The method used is always by spherical triangulation. Temperature fell from the peak in September of 1.49 to 1.29 in October. These are the monthly … Continue reading

Direct evidence that CO2 forcing alone determines Global Temperatures

The well known result that CO2 radiative forcing is approximately 5.3 Ln (C/CO) [1] is confirmed here by comparing decadal global temperature anomalies with CO2 concentrations. Positive feedbacks are not needed to explain the observed warming. A value of Transient … Continue reading

Deducing Climate Sensitivity from Decadal Temperature Data

Note: This post is superseded by the following post ! The transient climate sensitivity (TCR) is the observed average warming of the earth following a doubling of atmospheric CO2 concentration. Effectively this means the observed average temperature when CO2 levels … Continue reading
