As a prelude to a new book, Nigel Calder (who was the editor of New Scientist for four years in the 1960s) has written an op-ed for the Times (UK) basically recapitulating the hype over the Svensmark cosmic ray/climate experiments we reported on a couple of month ago (see Taking Cosmic Rays for a spin). At the time we pointed out that while the experiments were potentially of interest, they are a long way from actually demonstrating an influence of cosmic rays on the real world climate, and in no way justify the hyperbole that Svensmark and colleagues put into their press releases and more ‘popular’ pieces. Even if the evidence for solar forcing were legitimate, any bizarre calculus that takes evidence for solar forcing of climate as evidence against greenhouse gases for current climate change is simply wrong. Whether cosmic rays are correlated with climate or not, they have been regularly measured by the neutron monitor at Climax Station (Colorado) since 1953 and show no long term trend. No trend = no explanation for current changes.

WSJ Editorial Board: Head Still Buried in the Sand
) While the rest of the world has basically accepted the conclusion of the latest IPCC report, one small village still holds out against the tide – the Wall Street Journal editorial board. This contrasts sharply with the news section of the paper which is actually pretty good. They had a front-page piece on business responses to global warming issues which not only pointed out that business was taking an interest in carbon reduction, but the article more or less took as a given that the problem was real. However, as we have pointed out before, the editorial pages operate in a universe all their own.
This would not be of much concern if the WSJ wasn’t such an influential paper in the US. However, the extent of its isolation on this issue is evident from the amusing reliance on the error-prone Christopher Monckton. They quote him saying that the sea level rise predictions were much smaller than in IPCC TAR (no they weren’t), that the human contribution to recent changes has been ‘cut by a third’ (no it hasn’t), and that the Summary for Policy Makers (SPM) was written by politicians (no it wasn’t – the clue is in the name).
Even more wrong is the claim that “the upcoming report is also missing any reference to the infamous ‘hockey stick’ “. Not only are the three original “hockey stick” reconstructions from the IPCC (2001) report shown in the (draft) paleoclimate chapter of the new report, but they are now joined by 9 others. Which is why the SPM comes to the even stronger conclusion that recent large-scale warmth is likely to be anomalous in the context of at least the past 1300 years, and not just the past 1000 years.
Thus on any index of wrongness, this WSJ editorial scores pretty high. What puzzles us is why their readership, who presumably want to know about issues that might affect their bottom line, tolerate this rather feeble denialism. While we enjoy pointing out their obvious absurdities, their readers would probably be better off if the WSJ accepted Jeffery Sachs’ challenge. For if they can’t be trusted to get even the basic checkable facts right on this issue, why should any of their opinions be taken seriously?
Fraser Institute fires off a damp squib
New addition: Download an annotated pdf of the Fraser report. An interactive pdf file, to be read on the screen, is here, and a printable version is here. Suggestions for further commenting are welcome. Additions to the pdf have to be short, and tied to particular pieces of text or figures. And of course we will only incorporate comments that we deem to be scientifically sound and cogent.
*****************
While most of the world’s climate scientists were following the IPCC fest last week, a few contrarians left out in the cold were trying to to organize their own party.
An unofficial, “Independent Summary for Policymakers” (ISPM) of the IPCC Fourth Assessment report has been delivered by the Fraser Institute. It’s a long, imposing-looking document, resembling, come to think of it, the formatting of the real Summary for Policymakers (SPM) document that was released on Friday after final negotiations of the IPCC in Paris last week. The Fraser Institute has assembled an awesome team of 10 authors, including such RC favorites as tilter-against-windmills-and-hockey-sticks Ross McKitrick, and other luminaries such as William Kininmonth, MSc, M.Admin — whose most recent paper is “Don’t be Gored into Going Along” in the Oct-Nov issue of Power Engineer. To be fair, he did publish a paper on weather forecasting, back in 1973. According to the press release, the London kickoff event will be graced by the presence of “noted environmentalist” David Bellamy. It’s true he’s “noted,” but what he’s noted for is his blatant fabrication of numbers purporting to show that the world’s glaciers are advancing rather retreating, as reported here.
The IPCC Fourth Assessment SPM
) () (
) (
) We’ve had a policy of (mostly) not commenting on the various drafts, misquotes and mistaken readings of the Fourth Assessment report (“AR4” to those in the acronym loop) of the IPCC. Now that the summary for policy makers (or “SPM”) has actually been published though, we can discuss the substance of the report without having to worry that the details will change. This post will only be our first cut at talking about the whole report. We plan on going chapter by chapter, hopefully explaining the key issues and the remaining key uncertainties over the next few months. This report will be referenced repeatedly over the next few years, and so we can take the time to do a reasonable job explaining what’s in it and why.
Quick pre-SPM round-up
Tomorrow is the big day for all IPCC-watchers (and we’ll comment then) but in the meantime here are a few interesting tidbits floating around today.
First off, there are some curious patterns in the whitehouse.gov search engine. It turns out that it has been blocked from returning most results if the search phrase includes “global warming” – even if it’s from the President himself. For instance, searching for “issue of global” gives as top result the President’s Rose Garden speech in June 2001 on Global Climate Change, but searching for “issue of global warming” (which of course is the full phrase used) returns nothing. Hmmm…..
Secondly, Bill Nye (‘the underprepared science guy’) had a rather rough time of it up against Richard Lindzen on Larry King last night – an episode notable only for the regression back to the ‘false balance’ notion that most of the media has been moving away from (sigh…). However, tucked away at the end was a rather confused section, where it appears that Lindzen bet Nye that ice cores don’t have a resolution better than 2000 years. Now this is an odd claim, and an odder thing to bet on, since Greenland cores (GRIP, GISP2) and Antarctic cores (EPICA DML) have sub-annual resolution in many cases for the isotope (temperature) records, and at least decadal resolution (Law Dome, Siple Dome) for the greenhouse gases (CO2, CH4). It’s true that the very longest records (Vostok and Dome-C) have coarser resolution, but surely Lindzen doesn’t think they are the only ones that exist? So, to make up for Nye’s performance, he should at least get a quality bottle of scotch. Bill, let us know if Lindzen pays up!
Finally, there is an excellent article on the sausage making going on in Paris… more on that tomorrow.
House and Senate committee hearings
There are two hearings today from the new congress that are of relevance for RealClimate readers:
The House Oversight Committee is having hearings on the possible suppression of climate change science by the administration (streaming from here). Witnesses include Drew Shindell (NASA GISS), Roger Pielke Jr. and R. Piltz. Update: Full hearing video available at C-SPAN.
The Senate EPW Committee is having an open forum for senators to discuss climate change legislation (streaming from here).
Stern Science
) () Halldór Björnsson, William Connolley and Gavin Schmidt
Late last year, the UK Treasury’s Stern Review of the Economics of Climate Change was released to rapturous reception from all sides of the UK political spectrum (i.e. left and right). Since then it has been subject to significant criticism and debate (for a good listing see Rabbett Run). Much of that discussion has revolved around the economic (and ethical) issues associated with ‘discounting’ (how you weight welfare in the future against welfare today) – particularly Nordhaus’s review. We are not qualified to address those issues, and so have not previously commented.
However, as exemplified by interviews on a recent Radio 4 program (including with our own William Connolley), some questions have involved the science that underlies the economics. We will try and address those.
The Human Hand in Climate Change
Kerry Emanuel (whose influential scientific work we’ve discussed here previously) has written a particularly lucid and poignant popular article on climate change for the literary forum “Boston Review”. The article is entitled Phaeton’s Reins: The human hand in climate change. We thought it worth passing along.
When the mites go up…
Guest Commentary from Andy Baker, U. of Birmingham
It doesn’t seem obvious really. Going underground into caves, removing stalagmites and analysing their isotopic composition isn’t the first thing you would do to look for past climate information. But for nearly 40 years, there has been an active, and growing research community that investigates the climate records preserved in these archives. Stalagmites have recently received high profile use in climate reconstructions, for example records from China and Norway have featured in Moberg’s last millennium temperature reconstruction; in a northern hemisphere temperature reconstruction of the last 500 years and even been debated here on RealClimate. So it seems timely to review why on (or even under) earth should research go underground to look at surface climate.
Calling All Science Teachers
“An Inconvenient Truth,” the Davis Guggenheim documentary on global warming starring Al Gore’s presentation on the subject, provides an accurate, engaging, accessible, thought-provoking and (at times) even humorous introduction to one of the most important scientific issues of our time ( see our review of the movie). In some countries, viewing “An Inconvenient Truth” has actually become a required part of the science curriculum, and with good justification, we think. Given that the DVD is currently selling for $19.99 through Amazon.com, you’d think that the National Science Teachers’ Association ( NSTA) would jump at the chance to quickly get 50,000 free copies quickly into the hands of their members. Yet, when Laurie David, one of the producers of the film, made this offer to NSTA last November, it was summarily turned down on the grounds that the NSTA has a 2001 policy against “product endorsement” (as if Laurie David were trying to shop some new deodorant to high school science teachers). What in the world is going on here?
Before continuing with the history of NSTA’s bizarre decision, let us provide you with the most important information: Up to 50,000 US science teachers can receive a free copy of the DVD by filling out a simple request form here . The deadline for requesting your copy is January 18, so if you want a copy, take a few minutes to put in your request right away.
