How to be wrong

From the department for shooting fish in a barrel, David Appell has a nice post pointing out that Singer has been a bozo for years, predicting (in 1981) massive future declines in fossil oil use.

This may be a good place to link to another of DA’s posts, US Emissions to Stay Below Pre-Recession Peak Until 2028 which makes an interesting combination with Early Warning on US vehicle miles.

More Singer-is-a-bozo stuff

This is, as I said, shooting fish in a barrel. So I’ll just make it an update to this post rather than a new one. DA went to a talk by Singer that was riddled with errors. One bit stuck out:

Most egregious of his claims was that there has been no warming since 1975. As proof he put up a graph of UAH (University of Alabama at Huntsville) satellite data, compiled by the Christy/Spencer group. Singer said he calculated that it had zero linear trend. One audience member down front almost jumped out of his seat while pointing out that Singer was using version 5.0 of the UAH data, which is years old and had not been properly (and famously) corrected for satellite drift. UAH did that and their new data, version 5.4, now shows warming, and they list the trend at the bottom of their data page: +0.14°C/decade for the globe, +0.17°C/decade for land. Astonishingly Singer feigned ignorance of this.

Singer gave a talk at BAS, ooh, maybe 5 years back, and he was much the same then. He used junk data, and anytime anyone pointed this out, he put on the folksy-old-man persona and pretended he knew nothing about it. As a rhetorical trick, I don’t think it works well: rather than a poor old man being assailed by nasty young men pointing out his errors, he comes across as a senile old chap who doesn’t really know what he is talking about.
