A new measurement of Equilibrium Climate Sensitivity (ECS)

A dynamic analysis of global temperature data  gives a value of ECS = 2.5C ± 0.5C . Values above 3.0C or below 2.0C are ruled out. This analysis is based on two assumptions: 1) That net climate forcing follows that … Continue reading

HadCRUT 4.6 temperatures compared

CRUTEM station data for October was released a few days ago. So I can now make a direct comparison of different surface averaging methodologies. The calculated October temperature anomaly for the 3 different spatial averages, as described previously are the following … Continue reading

Icosahedral Binning

The earth is roughly a sphere so an unbiased method to bin surface temperature data is to treat the surface itself in 3D. Ideally each bin should cover exactly the same surface area, so that the global average is simply … Continue reading
