February 2015 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference 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 February 2015 and HADCRUT4 and NCDC through January 2015—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through February 2015. INITIAL NOTES: For discussions of…

The 2014-15 El Niño – Part 23 – NOAA’s Forward-Looking El Niño Advisory Was Also Dictated by Conditions since Last September

Guest Post by Bob Tisdale After many months of borderline El Niño conditions in the tropical Pacific, yesterday NOAA finally declared an El Niño was occurring. See Anthony Watts’s post NOAA Claims: ‘Elusive El Niño arrives’ – the question is, ‘where’? at WattsUpWithThat. It includes a number of items like the announcement by NOAA, NOAA’s…

Another Couple of Notes about Michael Mann’s “Faux Pause” Post and Steinman et al. 2015

Guest Post by Bob Tisdale We discussed Steinman et al. (2015) and Michael Mann’s post about it at RealClimate in the article On Steinman et al. (2015) – Michael Mann and Company Redefine Multidecadal Variability And Wind Up Illustrating Climate Model Failings. This brief post adds to that discussion. THE PAUSE, HIATUS, SLOWDOWN (WHATEVER) IN GLOBAL…

On Steinman et al. (2015) – Michael Mann and Company Redefine Multidecadal Variability And Wind Up Illustrating Climate Model Failings

Guest Post By Bob Tisdale For the past few years, we’ve been showing in numerous blog posts that the observed multidecadal variations in sea surface temperatures of the North Atlantic (known as the Atlantic Multidecadal Oscillation) are not represented by the forced components of the climate models stored in the CMIP5 archive (which were used…
