NASA and Nicholas Stern start to purge their websites

The fallout from what appears to be a cascade of revelations about the sloppy and dishonest goings on at the IPCC begins.

NASA here.

Lord Stern here:

Last night I pointed out how NASA had quietly purged IPCC AR4 referenced glacier melting claims from its climate.nasa.gov website, especially since they upped the year from 2035 to 2030 on their own. Now Roger Pielke Jr. points out that another curious purge has been spotted:

Excerpts:

There is another important story in involving the Muir-Wood et al. 2006 paper that was misrepresented by the IPCC as showing a linkage between increasing temperatures and rising damages from extreme weather events. The Stern Review Report of the UK government also relied on that paper as the sole basis for its projections of increasing damage from extreme events. In fact as much as 40% of the Stern Reivew projections for the global costs of unmitigated climate change derive from its misuse of the Muir-Wood et al. paper.

…

As I was preparing this post, I accessed the Stern Review Report on the archive site of the UK government to capture an image of Table 5.2. Much to my surprise I learned that since the publication of my paper, Table 5.2 has mysteriously changed! Have a look at the figures below.

The figure immediately below shows Table 5.2 as it was originally published in the Stern Review (from a web archive in PDF), and I have circled in red the order-of-magnitude error in hurricane damage that I document in my paper (the values should instead by 10 times less).

Now, have a look at the figure below which shows Table 5.2 from the Stern Review Report as it now appears on the UK government archive (PDF), look carefully at the numbers circled in red:

There is no note, no acknowledgment, nothing indicating that the estimated damage for hurricanes was modified after publication by an order of magnitude. The report was quietly changed to make the error go away. Of course, even with the Table corrected, now the Stern Review math does not add up, as the total GDP impact from USA, UK and Europe does not come anywhere close to the 1% global total for developed country impacts (based on Muir-Wood), much less the higher values suggested as possible in the report’s text, underscoring a key point of my 2007 paper.
