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

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 … Continue reading

The 50-50 argument

Originally posted on Climate Etc.:
by Judith Curry Pick one: a)  Warming since 1950 is predominantly (more than 50%)  caused by humans. b)  Warming since 1950 is predominantly caused by natural processes. When faced with a choice between a) and…

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

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 today online in ScienceMag (link to paper follows), that’s not going to … Continue reading

On The Recent Record-High Global Sea Surface Temperatures – The Wheres and Whys

NOAA’s State of the Climate Report for June 2014 included the bullet point under global highlights (my boldface): For the ocean, the June global sea surface temperature was 0.64°C (1.15°F) above the 20th century average of 16.4°C (61.5°F), the highest … Continue reading

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 … Continue reading

The 2014/15 El Niño – Part 15 – August 2014 Update – An El Niño Mulligan?

Yes, I’m using the term Mulligan as in a replayed golf shot. Ocean-atmosphere processes have consumed most of the warm water in the eastern equatorial Pacific from the downwelling (warm) Kelvin wave that had crossed the Pacific earlier this year. … Continue reading

July 2014 Sea Surface Temperature (SST) Anomaly Update

WEEKLY GLOBAL SEA SURFACE TEMPERATURE ANOMALIES Weekly global sea surface temperature anomalies are still reaching higher, now easily above the peak reached during the 1997/98 El Niño.  The vast majority of this new warming comes from the North Pacific.  I’ll … Continue reading
