A Note on the 50-50 Attribution Argument between Judith Curry and Gavin Schmidt

Guest essay by Bob Tisdale | Judith Curry and Gavin Schmidt are arguing once again about how much of the global warming we’ve experienced since 1950 is attributable to human-induced global warming.  Judith’s argument was presented in her post The 50-50 argument at ClimateEtc (where this morning there were more than 700 comments…wow…so that thread…

Hurricane Development Region Sea Surface Temperature Update – August 2014

The peak of the Atlantic Hurricane season is rapidly approaching.  See the NOAA Hurricane Climatology  graph to the right.  (Give it a click for a full-sized version.) Hurricane frequency tends to peak in mid-September. In the May 2014 post Hurricane Development Region Sea Surface Temperature Anomalies as We Start the 2014 Season, we presented sea surface…

Will the Next El Niño Bring an End to the Slowdown in Global Surface Warming?

Rebuttal to Chen and Tung (2014) highlighted in “Cause for ‘The Pause’ #38 – Cause of global warming hiatus found deep in the Atlantic Ocean“ Numerous scientific papers have reported the hiatus in global surface warming will end with the next El Niño event. But according to a new paper by Chen and Tung published…

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…

Recent Hawaiian Tropical Cyclones – Sea Surface Temperature Anomalies of the Storm Tracks

It never fails. Hurricanes and tropical cyclones always bring out the manmade global warming alarmists, with their claims of unusually warm sea surface temperatures along the storm tracks. Of course those fictionally warmed sea surface temperatures were caused by rising CO2 emissions. We expected and saw that nonsense when Sandy struck the east coast of…
