Gavin Schmidt Warns Donald Trump Not to Interfere with the NASA Climate Division

Guest essay by Eric Worrall Gavin Schmidt, director of the NASA Goddard Institute for Space Studies, has “warned” President-elect Donald Trump not to interfere with their climate activities. Schmidt maintains the GISS global temperature series, arguably the most adjusted of all the global temperature products. ‘Global warming doesn’t care about the election’: Nasa scientist warns…

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

Guest Post by Bob Tisdale UPDATE: All graphs with UAH lower troposphere temperature data have been updated from beta version 6.4 to 6.5. Thanks, Nick Stokes. This means Figure 4 and Figures 6 through 9 have been revised. # # # The GISS Land-Ocean Temperature Index jumped upwards more than 0.2 deg C from September…

Massive NASA Hack, including Climate Systems

Guest essay by Eric Worrall A group of hackers, apparently part of a community of hackers who spend their time casually cruising poorly defended US government computers, have busted into and claim to have interfered with sensitive NASA systems, including climate monitoring projects. Hackers have released online 250GB of data purloined from NASA systems –…

On the Elusive Absolute Global Mean Surface Temperature – A Model-Data Comparison

Guest Post by Bob Tisdale With the publication of the IPCC 5th Synthesis Report, I thought there might be some interest in a presentation of how well (actually poorly) climate models simulate global mean surface temperatures in absolute terms. That is, most climate model outputs are presented in terms of anomalies, with data shown as…

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…
