Here’s a major complaint about BEST now that I’ve looked at it more closely. If BEST wanted to make their work as widely available as possible, then they should have done their statistical programming in R so that it was available in a public language. And made their data available as organized R-objects. I’ve taken […]
I doubt that there are many people who’ve made as many presentations to NAS panels as they have to university seminars in climate departments. Since I’ve done one of each, I presently qualify. (My only invitation to make a presentation to a university climate department was to Georgia Tech in early 2008. I’ve made a […]
Rich Muller sent me the BEST papers about 10 days ago so that I would have an opportunity to look at them prior to their public release. Unfortunately, I’ve been very busy on other matters in the past week and wasn’t able to get to it right away and still haven’t had an opportunity to […]
Donna Laframboise’s book on IPCC has now been published. Available at Amazon or as pdf here for $5. The self-indulgent and petulant behavior of leaders in the climate community is one of the first things that impresses outsiders. Donna aptly uses the metaphor of a “spoiled child” to describe IPCC and the climate community. Her […]
Quiet blogging lately for a variety of reasons. In today’s post, I’m going to spend some time parsing RegEM (Truncated Total Least Squares) methodology, in itself hardly a standard technique, but particularly quirky in the Mann et al 2008 implementation. In the analysis leading up to O’Donnell et al 2010, we ported the Tapio Schneider […]
William Brune, who acted as a “consultant” to the Penn State Inquiry Committee will be discussing the Mann misconduct “inquiry” in Boulder tomorrow Wednesday, October 5, 2:15 PM (Refreshments at 2:00 PM) at the David Skaggs Research Center, Room 2A305. Directions http://www.esrl.noaa.gov/about/visiting.html The seminar is a Chemical Science Division seminar entitled “Climategate, Michael Mann, and […]
The recent report of the EPA Office of Inspector General(OIG) contains a remarkable dispute between the OIG on the one hand and EPA and the Office of Management and Budget (OMB) on the other as to whether the Technical Support Document (TSD) for the Endangerment Finding was a “highly influential scientific assessment”, a defined category […]
In our recent discussion of Dessler v Spencer, UC raised monthly centering as an issue in respect to the regressions of TOA flux against temperature. Monthly centering is standard practice in this branch of climate science (e.g. Forster and Gregory 2006, Dessler 2010), where it is done without any commentary or justification. But such centering […]
Scripts and data for Lindzen and Choi 2011 are now online at CA here together with the original article. It will take me a little while to get to this. The scripts are in IDL. Translations to R welcomed.
Dessler (2011) reported the following: A related point made by both LC11 and SB11 is that regressions of TOA flux or its components vs. ΔTs will not yield an accurate estimate of the climate sensitivity λ or the cloud feedback. This conclusion, however, relies on their particular values for σ(ΔFocean) and σ(ΔRcloud). Using a more […]
