All the RSS Temperature Trends that are Fit to Plot

Of course they…

Change to Raw USHCN Value after Homogenization Estimate

Approximately 92% (or 99%) of USHCN surface temperature data consists of estimated values

An analysis of the U.S. Historical Climatological Network (USHCN) shows that only about 8%-1% (depending on the stage of processing) of the data survives in the climate record as unaltered/estimated data. Guest essay by John Goetz A previous post showed that the adjustment models applied to the GHCN data produce estimated values for  approximately 66% of…
