James Hansen, the 68 year old icon of climate research from the NASA Goddard Institute for Space Studies (NASA GISS), has brought off another coup to combine his science with political alarmism. “We compare global temperature reconstructions of GISS, NCDC, and HadCRUT. We conclude that global temperature continued to rise rapidly in the past...

Global Temperature 1979-2008 marks an anniversary of 30 years of temperature history of the satellite era. Since the World Meteorological Organization has defined “climate” as “the average weather” over a classical period of 30 years, we have now a record of a full climate period of near surface temperatures as measured by satellites. This...

The above graph shows the revision of the RSS-MSU temperature history. Blue shades signify upward corrections and dark yellow shades signify downward corrections, resulting in an overall decrease of global warming from 0.169 to 0.159° per decade. Temperature graphs of various metrics draw closer together. Until 2003 they were “all over the place” (see “reasononline”)....

In the above graph, the global average surface temperature anomalies from 1979 to 2008 (September update of five different metrics) are displayed. Climatepatrol regularly updates the past 30-year trendline of “global warming” and provides you with the average slope of three surface station metrics (Nasa, Noaa, Hadley Centre) and two satellite metrics. Results and comments Climatepatrol...
