USHCN Surface Temperatures, 1973-2012: Dramatic Warming Adjustments, Noisy Trends

Since NOAA encourages the use the USHCN station network as the official U.S. climate record, I have analyzed the average [(Tmax+Tmin)/2] USHCN version 2 dataset in the same way I analyzed the CRUTem3 and International Surface Hourly (ISH) data. The main conclusions are: 1) The linear warming trend during 1973-2012 is greatest in USHCN (+0.245 […]

Could Arctic Sea Ice Decline be Caused by the Arctic Oscillation?

While the IPCC claims that recent Arctic sea ice declines are the result of human-caused warming, there is also convincing observational evidence that natural cycles in atmospheric circulation patterns might also be involved. And unless we know how much of the decline is natural, I maintain we cannot know how much is human-caused. In 2002, […]

What Causes the Large Swings in Global Satellite Temperatures?

One of the most frequent questions I get pertains to the large amount of variability seen in the daily global-average temperature variations we make available on the Discover website. From Aqua AMSU ch. 5, these temperatures can undergo wide swings every few weeks, leading to e-mail questions like, Is the satellite broken? Unusually good examples […]

UAH Global Temperature Update for January 2012: -0.09 deg. C

The global average lower tropospheric temperature anomaly for January, 2012 took a precipitous plunge, not totally unexpected for a La Nina January (click on the image for the full-size version): The 3rd order polynomial fit to the data (courtesy of Excel) is for entertainment purposes only, and should not be construed as having any predictive […]

Daubert and the Admissibility of Climate Models as Evidence in a Court of Law

Institute Director Dr. Roy Spencer and attorney Brooks Harlow authored an article in Energy Law Journal entitled: An Inconvenient Burden of Proof? CO2 Nuisance Plaintiffs Will Face Challenges in Meeting the Daubert Standard. Dr. Spencer comments on the article here. The article synopsis follows: Litigation regarding “climate change” allegedly caused by emissions of “greenhouse gases” […]

Addressing Criticisms of the UAH Temperature Dataset at 1/3 Century

The UAH satellite-based global temperature dataset has reached 1/3 of a century in length, a milestone we marked with a press release in the last week (e.g. covered here). As a result of that press release, a Capital Weather Gang blog post by Andrew Freedman was dutifully dispatched as damage control, since we had inconveniently […]

Climate Science Money Trail Calls into Question Motive of Editor’s Resignation

As President Clinton famously once observed, politics is a contact sport. And the politics surrounding climate science is no exception. The latest example stems from the climate establishment’s reaction to a research paper by University of Alabama climatologist Roy Spencer published in the geography journal, Remote Sensing. (Dr. Spencer, who also happens to be on […]
