Hottest year ever? Skeptics question revisions to climate data

2012 was a scorcher, but was it the warmest year ever? A report released this week by the National Oceanic and Atmospheric Agency (NOAA) called it “the warmest year ever for the nation.” Experts agree that 2012 was a hot year for the planet. But it’s that report — and the agency itself — that’s […]

Our Chaotic Climate System

Over the last quarter century, mainstream climate science has changed dramatically, from a paradigm where climate changes naturally to one where climate forever remains the same unless humans meddle with it. The reasons for this paradigm shift are clearly not based on science. Sure, you can always analyze some dataset in such a way that […]

UAH V5.5 Global Temp. Update for Sept. 2012: +0.34 deg. C

As discussed in my post from yesterday, the spurious warming in Aqua AMSU channel 5 has resulted in the need for revisions to the UAH global lower tropospheric temperature (LT) product. Rather than issuing an early release of Version 6, which has been in the works for about a year now, we decided to do something […]

Junk Science Week: Epic climate model failure

Nearby is a running graph of 5-year averages for the tropical tropospheric temperature, climate models versus observations. In all, 73 climate models from the Coupled Model Intercomparison Project are plotted against observations so that their respective 1979-2012 trend lines all intersect in 1979, which we believe is the most meaningful way to simultaneously plot the […]

UAH Global Temperature Update for April 2012: +0.30°C

The global average lower tropospheric temperature anomaly increased again in April, 2012, to +0.30°C., with warming in both Northern and Southern Hemispheres, but slightly cool conditions persisting in the tropics (click on the image for the full-size version): The corresponding April anomaly from RSS, using a common baseline period of 1981-2010, is considerably cooler at […]

Our Response to Recent Criticism of the UAH Satellite Temperatures

by John R. Christy and Roy W. Spencer University of Alabama in Huntsville A new paper by Stephen Po-Chedley and Quang Fu (2012) (hereafter PCF) was sent to us at the end of April 2012 in page-proof form as an article to appear soon in the Journal of Atmospheric and Oceanic Technology. The topic of […]

New Evidence Our Record Warm March was Not from Global Warming

As part of my exploration of different surface temperature datasets, I’m examining the relationship between average U.S. temperatures and other weather variables in NOAA’s Integrated Surface Hourly (ISH) dataset. (I think I might have mistakenly called it “International” before, instead of “Integrated” Surface Hourly). Anyway , one of the things that popped out of my […]
