The Politicization of Climate Science Is NOT a Recent Phenomenon

Guest Post by Bob Tisdale There’s lots of yacking around the blogosphere and mainstream media about President-elect Donald Trump politicizing climate science. But it’s nothing new. Climate science became a tool for pushing political agendas almost 3 decades ago. In 1988, the United Nations, a political body, founded the global-warming-report-writing entity called the Intergovernmental Panel…

October 2016 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

Guest Post by Bob Tisdale This post provides updates of the values for the three primary suppliers of global land+ocean surface temperature reconstructions—GISS through October 2016 and HADCRUT4 and NOAA NCEI (formerly NOAA NCDC) through September 2016—and of the two suppliers of satellite-based lower troposphere temperature composites (RSS and UAH) through October 2016. It also…

Something to Keep an Eye On – The Large Blue Ribbon of Below-Normal Sea Surface Temperatures in the North Pacific

Guest Post by Bob Tisdale The weather pattern that created Siberia’s well-below-normal land surface air temperatures in October 2016 … October 2016 Land Surface Air Temperature Anomalies (GHCN-CAMS through KNMI Climate Explorer) …has apparently extended eastward.  It is now influencing the sea surface temperatures of the North Pacific and creating an atypical large swath of…

THE BLOB Has Dissipated

Guest Post by Bob Tisdale Animation 1 – Sea Surface Temperature Anomaly Maps from the CMC Environment Canada (September 17, 2016 and October 27, 2016) The Blob was the name given to the area of elevated sea surface temperature anomalies in the eastern extratropical North Pacific. It formed in 2013, coupling with a ridge of…

September 2016 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

Guest Post by Bob Tisdale This post provides updates of the values for the three primary suppliers of global land+ocean surface temperature reconstructions—GISS through September 2016 and HADCRUT4 and NCEI (formerly NCDC) through August 2016—and of the two suppliers of satellite-based lower troposphere temperature composites (RSS and UAH) through September 2016.  It also includes a…

The Divergence between Surface and Lower Troposphere Global Temperature Datasets and its Implications

Guest Post by Bob Tisdale I include a graph in my monthly global surface temperature and lower troposphere temperature anomaly updates that compares the average of the global surface land+ocean temperature anomaly products (from GISS, NCEI and UKMO) to the average of the global lower troposphere temperature anomaly products (from RSS and UAH).  (See Figure…
