October 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update

Watts Up With That?

Guest Post by Bob Tisdale

I’ve added a graph of the difference between the observed global temperature anomalies (GISS LOTI) and the climate model simulations of that metric by the models stored in the CMIP5 archive (used by the IPCC for their 5th Assessment Report).  As a result of the hiatus (slowdown) in global surface warming, the current difference between the models and data is the largest (worst) it has been in about 100 years (based on a 61-month average).

This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through October 2014 and HADCRUT4 and NCDC through September 2014—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through October 2014.

The three surface data suppliers have been claiming record high monthly values recently.  This is, in part, due to the record high sea surface…
