And What Have the Average Temperatures of Earth’s Surfaces Been Recently in Absolute Terms, Not Anomalies?

The answers may surprise you.

So, for the purpose of this very simple illustration and comparison, and for the discussions it will generate, I’ve added 14 deg C to the annual GISS LOTI data available here, and added 14.186 deg C to the annual Berkeley Earth data. I also compared them to the 12.04 deg C to 15.05 deg C range of hindcast preindustrial global mean surface temperatures from the climate model ensemble members discussed earlier. See Figure 3. Not too surprisingly, the Berkeley Earth and GISS global mean surface temperatures, in absolute form, are very similar, with only a 0.1 deg C difference during the most recent 30-years.
