Here is an account of an intriguing review carried out by NASA in response to a civilian Request for Review. NASA’s webpage on the Data Quality Act states: In accordance with the President’s Management Council, NASA implements the Office of Management and Budget (OMB) following requirements for quality of information. Section 515, “OMB Guidelines for […]
I’ve been seeking an engineering-quality exposition of how 2.5 deg C is derived from doubled CO2 for some time. I posted up Gerry North’s suggestion here , which was an interesting article but hardly a solution to the question. I’ve noted that Ramanathan and the Charney Report in the 1970s discuss the topic, but these […]
This topic has spilled into Unthreaded. The one comment that I would be inclined to make on this is that, if people are depending on water from glacier retreat in tropical and temperate settings, then it seems to me that their water supply would be equally diminished by glacier stabilization or advance, not just by […]
Reader Michael Smith asked about the provenance of Figure 1.1 in the SPM for the AR4 Synthesis Report. While we’ve had some discussions of WG1, we’ve not discussed the Synthesis Report before. While following up the references for this Figure, I encountered the WG1 FAQ – a document which I had previously not noticed. The […]
Roy Spencer has an interesting post on cloud feedback at Pielke Sr (which doesn’t permit comments.) He observes: On August 8, 2007, I posted here a guest blog entry on the possibility that our observational estimates of feedbacks might be biased in the positive direction. Danny Braswell and I built a simple time-dependent energy balance […]
Michael Smith asks: Since we are discussing uncertainty intervals, I have a question — probably a dumb one, but what the heck. In the Summary for Policy Makers, IPCC 4th AR, there is a graph “Figure SPM.1” on page 3. See here: http://www.ipcc.ch/pdf/assessment-report/ar4/syr/ar4_syr_spm.pdf The graph show “Global average surface temperature” since 1850. It includes individual […]
Pierrehumbert recently made the following statement about the truncation of data: Whatever the source of the purported … data, there is no legitimate reason in a paper published in 2007 for truncating the … record … as they did. There is, however, a very good illegitimate reason, in that truncating the curve in this way […]
It is a red-letter rule in business that transactions between a company and its insiders or employees must be disclosed. Some of the most egregious breaches by Enron were its attempts to avoid disclosure of writeoffs by selling worthless assets to the infamous limited partnerships organized by company insiders for equally worthless paper issued by […]
