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 the two lower troposphere temperature datasets are for the most recent month. The HADCRUT4 and NCDC data lag one month.
This post contains graphs of running trends in global surface temperature anomalies for periods of 13+ and 17+ years using GISS global (land+ocean) surface temperature data. They indicate that we have not seen a warming halt (based on 13-years+ trends) this long since the late-1970s or a warming slowdown (based on 17-years+ trends) since about 1980. I used to rotate the data suppliers for this portion of the update, also using NCDC and HADCRUT…
