AMac: Upside Down Mann Lives on in Kemp et al 2011

AMac: Yesterday, Kemp et al. 2011 was published in PNAS, relating sea-level variation to climate over the past 1,600 years (UPenn press release). Among the authors is Prof. Mann. (Kemp11 is downloadable from WUWT.) Figs. 2A and 4A are “Composite EIV global land plus ocean global temperature reconstruction, smoothed with a 30-year LOESS low-pass filter”. […]

US Science Committee Asks IPCC to Implement COI Policy

Judy Curry draws attention to a letter from the Chairman of the Oversight Subcomittee of the US Science Committee to the UN Chairman asking that IPCC not be permitted to delay implementation of Conflict of Interest policy until after AR5 – press release here. Judy observes that a distinction should be made between Lead Authors […]

Whitewashing IPCC Renewables: the Carbon Brief

The Carbon Brief, an advocacy site funded by the European Climate Foundation, as part of the ongoing whitewashing of IPCC’S deceptive press release on renewables, today purported to blame journalists for being tricked by the IPCC press release, stating: Journalists were also under no obligation to adopt the framing of the IPCC’s press release. The […]

Lynas’ Questions

As most CA readers know by now, the following widely-disseminated lead statement to the IPCC press release announcing the Renewables Report was untrue. Close to 80 percent of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies a new report shows. On June 16, Mark […]

Pachauri: No Conflict of Interest Policy for AR5

Yesterday, IPCC chairman Pachauri told Oliver Morton of The Economist at an IPCC event in Brussels that conflict of interest policies would not not apply to AR5 authors. IPCC thereby sabotaged recommendations from the Interacademy Council and announced its plans to evade the conflict of interest policies passed at the 33rd IPCC plenary only a […]

IPCC Sabotages an Interacademy Recommendation

In the wake of Climategate, IPCC was more or less forced to establish a review of its procedures, carried out by the Interacademy Panel. One of its key recommendations was on conflict of interest – more on this later. A related recommendation called for the formation of an Executive Committee, with at least 3 members […]

Responses from IPCC SRREN

Some follow-up on responses to yesterday’s post by IPCC and others. My interest in SRREN had been attracted by the following lead to the IPCC press release announcing SRREN: Close to 80 percent of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies a new […]

IPCC WG3 and the Greenpeace Karaoke

On May 9, 2011, the IPCC announced (archive) Close to 80 percent of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies a new report shows. In accompanying interviews, IPCC officials said that the obstacles were not scientific or technological, but merely a matter of political […]

Lindzen’s PNAS Reviews

Chip Knappenberg has published Lindzen’s review correspondence with PNAS at Rob Bradley’s blog here. Most CA readers will be interested in this and I urge you to read the post, taking care to consult the attachments. (I would have preferred that the post include some excerpts from the attachments.) The post focuses to a considerable […]

McShane and Wyner Weights on Mann 2008 Proxies

Most CA readers are aware that proxy reconstructions use linear methods and that, accordingly, all the huffing and puffing of complicated multivariate methodologies simply end up assigning a vector of weights. Surprisingly this obvious point was not understood by paleos when I started in this field. Because one can assign a vector of weights, it’s […]
