Fool Me Twice: Fighting the Assault on Science in America” was officially released last night in Minneapolis with appropriate fanfare and celebration. Everyone who gets to know Shawn likes him from the start and quickly learns to respect him and eventually hold him with a certain amount of well-earned awe, and like any book, we’ve…

Gobal Warming is Melting the Ice Caps

My first job as an archaeologist in Boston (having moved there from New York) had to do with Deer Island, the northern of two islands that separate Boston’s Inner and Outer Harbors. The actual archaeology was uninteresting but the historical research was fascinating. Among the things I learned is that Boston’s Inner Harbor regularly froze…

The first global map of the salinity, or saltiness, of Earth’s ocean surface produced by NASA’s new Aquarius instrument reveals a rich tapestry of global salinity patterns, demonstrating Aquarius’ ability to resolve large-scale salinity distribution features clearly and with sharp contrast. NASA/GSFC/JPL-Caltech One of NASA’s newest Big Sci machines has generated a high quality map…

In order to do good climate science, you have to understand and control for the sources of variation in the system. In any system that involvs metric change over time, there are four sources of variation:

I want to say a word about what a proxyindicator is. And isn’t.

Cloud Gate Link Cloud!

You all know about the latest dustups and new research related to climate change, including the resignation of the Editor-in-Chief of a major journal as well as some new papers about global warming. There has been so much activity over recent days that I thought a new link farm would be a good thing. So,…

The question of whether clouds are the cause of global warming has been settled: No, they are not.

Cosmic Rays Do Not Cause Global Warming

On the face of it, it is impossible. Cosmic rays vary over time, and climate varies over time, and the two variations do not correspond. Global temperature has been going up over the last century, in correspondence with increased of atmospheric CO2, and this makes sense because the physics says that CO2 is a greenhouse…

There has been a major dust-up in the climate denialist world. A study published in late July made false claims and was methodologically flawed, but still managed to get published in a peer reviewed journal. The Editor-in-Chief of that journal has resigned to symbolically take responsibility for the journal’s egregious error of publishing what is…

The Inspector General of the National Science foundation has completed an investigation into falsifying research data, concealing or deleting emails or other data, misusing privileged information, and seriously deviating form accepted practices in relation to climate change research by climate scientist Michael Mann. This investigation, just completed, confirms what has been determined by other previous…
