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Note: This post is superseded by the following post !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

September’s Global Temperature was 1.44C

September’s global average temperature was 1.44C. This beat the previous record high monthly temperature recorded in September 2016 (1.22C). There was a strong El Nino , and the Americas, Europe and Antarctica were all warmer than usual.  Here is an … Continue reading
