Here are Judith Curry’s Comments on the Wegman Report. I appreciate these sorts of contributions and am obviously relying on such contributions (Willis, bender, etc.) more and more.
I’m quite happy to publish other people’s criticisms of topical and semi-topical papers. Judith Curry has sent in the following comments on Klotzbach et al, (mentioned on roadmap), abridged by her from a previous post on the tropical listserv, responding to specific talking points on the Klotzbach paper that were posted on Gray’s website.
Climate Audit has been considered – at least as a phenomenon – in a couple of courses. Kenneth Blumenfeld’s students had a different reaction than the Georgia Tech students. Earlier this year, I wrote a short comment about a post that Kenneth had made at realclimate about this, which I am re-posting in its entirety. […]
UKweatherworld has a thread where people don’t comment but simply contribute references on the Holocene Optimum. I’m going to start doing things like this as a way of keeping track of things. People have contributed data but it’s impossible to keep track of. This thread is going to consist only of scripts and data relevant […]
Last year, when Moberg was published, I pointed out witha slightly arched eyebrow that one of the two most important contributors to any 20th century HS-ness in Moberg was the increasing percentage of subpolar foraminifera (G. Bulloides) in the Arabian Sea – intuitively not a direct indicator of warming. Having visited the foraminifera literature in […]
Willis writes in: While researching ocean drill cores at the WCDC, I stumbled across Mann’s borehole data. One of the proxies used for historical temperature reconstruction is "borehole temperature", the temperature down in the ground. In 2002, Michael Mann et al. published a study called Optimal surface temperature reconstructions using terrestrial borehole data. It is […]
Thanks to Judith Curry for sending along these candid comments from a couple of her students about climateaudit. There has been discussion at the other thread wshich I’d prefer move to this thread. Here is the report from the Georgia Tech hurricane class discussion on the climateaudit hurricane threads. Two students were assigned to make […]
Here is a sociological study of how GCM modelers relate to their models. [Lahsen, 2005. Seductive Simulations? Uncertainty Distribution Around Climate Models, Social Studies of Science, 35, 895-922.] I kid you not. Lahsen: “At least at the time of my fieldwork, close users and potential close users at NCAR (mostly synoptically trained meteorologists who would […]
I think that I can give a very simple explanation of just how bizarre the climate reconstruction by Jim Hansen is. The graph below shows the actual Mg/Ca values for ODP806B, which is used in his reconstruction. The orange point is a modern sample in 27.2 deg C water (a value of 4.5, higher than […]
