On the Biases Caused by Omissions in the 2014 NOAA State of the Climate Report

Guest Post by Bob Tisdale [Update:  Corrected a few typos in the paragraph before Figure 4. My thanks to rogerknights.] I hadn’t read the NOAA State of the Climate (SOTC) Report for 2014 when I prepared the post Does the Uptick in Global Surface Temperatures in 2014 Help the Growing Difference between Climate Models and Reality?…

On the Elusive Absolute Global Mean Surface Temperature – A Model-Data Comparison

Guest Post by Bob Tisdale With the publication of the IPCC 5th Synthesis Report, I thought there might be some interest in a presentation of how well (actually poorly) climate models simulate global mean surface temperatures in absolute terms. That is, most climate model outputs are presented in terms of anomalies, with data shown as…

September 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

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

August 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

Guest Post by Bob Tisdale This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through August 2014 and HADCRUT4 and NCDC through July 2014—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through August 2014. Initial Notes: GISS LOTI, and…

July 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through July 2014 and HADCRUT4 and NCDC through June 2014—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through July 2014. The map to the above right shows the July 2014…
