GISS Global Land-Ocean Temperature Index Vs GHCN

Guest analysis by Mark Fife This is the state of the world’s surface temperatures according to NASA’s Goddard Institute for Space Studies from 1880 through 2017. It is indeed a very bleak picture. As I see it, this is showing an exponential rise in temperatures starting at the beginning of the 20th century. Of course,…

Changes to the GISS Land Surface Air Temperature-Based Dataset Have Increased Reported Long-Term Global Warming

No surprise there. But there are also periods when reported shorter-term global warming and global cooling have been decreased. Guest Post by Bob Tisdale This post discusses changes to a global surface temperature dataset from the Goddard Institute of Space Studies (GISS) that is based solely on land-surface air temperature data.  We’re going to compare…

September 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly 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 September 2014 and HADCRUT4 and NCDC through August 2014—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through September 2014. The three surface data suppliers…

August 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly 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 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…
