0435: Briffa: Pathetic GRL Hockey Stick Paper A Step Backwards In Time And Understanding

Briffa speaks out about the “Pathetic Paper“, with the added bonus of Edward Cook’s thoughts about multi-century temperature reconstructions:

subject: Re: An idea to pass by you
to: Edward Cook

[…] The basic point is that I (and I think [Tim Osborn]) agree that Mike and Phil’s latest contribution is a step backwards ( in time and understanding ) – well in reality I do not believe it is a step forward.

At 08:32 AM 9/3/03 -0400, [Edward Cook] wrote:

[…] I am afraid the Mike and Phil are too personally invested in things now (i.e. the 2003 GRL paper that is probably the worst paper Phil has ever been involved in – Bradley hates it as well) […] Without trying to prejudice [a newly proposed] work, but also because of what I almost think I know to be the case, the results of this study will show that we can probably say a fair bit about < 100 year extra-tropical NH temperature variability (at least as far as we believe the proxy estimates), but honestly know fuck-all about what the > 100 year variability was like with any certainty (i.e. we know with certainty that we know fuck-all)..

Data Sharing And Proprietary Periods, Away From The Climate Madness


The policy for the future mission will require the immediate dissemination of data.
“You get a larger community and you get a bigger workforce for free,” he says.
“It’s clear that the more people you get involved, the more support you get.”

How often have climate scientists lamented their inability to share their data, either because evil people might use them “improperly”, or because it is unfair that somebody take advantage of all their hard work.

Is this a problem of climate science alone? Perhaps, it is. How strange.

From the UK Space Agency, about the Planck mission:

the proprietary period, which nominally ends with the release of the scientific products to the community 3.5 yr after launch, i.e. in January 2013.

From the Planck mission organization itself: “Planck Science Management Plan

The nature of the mission is such that the data products can only be generated from an analysis of the full set of data; i.e. distribution of partial sets of data before the complete set is processed is not useful and will be avoided. In particular, all of the data acquired over the duration of the mission will be simultaneously used to calibrate and remove systematic effects. Thus, the time at which the 1-year proprietary period begins can be appropriately defined as the time at which the 9 all-sky channel maps (the main product described above) have reached a level of maturity such that they could be delivered to the community. The exact time when this level is reached will be determined by the PST, but will not be later than 1 year after the spacecraft power has been switched off.

It is worth noting here that the 1-year proprietary period will also be used to prepare the physical means of distribution of the scientific data products to the astronomical community, and the associated documentation (the ?Explanatory Supplement”); given the large amounts of data involved (in particular in the time series) this operation will require a non-negligible amount of time.

The Planck Mission Science Case, from Helsinki:

The observing program lasts 14 months. The Planck data will be made public two years after completion of the mission, in 2012. Prior to this, during the proprietary period, the data is analyzed and used by Planck Scientists and their collaborators

And now about the large European astronomical observatories (note how much emphasis there is on making the data easy to share):

Larger telescopes, more sophisticated instrumentation and solid state detectors have increased the efficiency of the astronomical observations by several orders of magnitude. All the data collected by these new instruments are produced directly in digital form and stored on computer accessible media. Controlled calibration procedures are applied to the raw data that then fill Science Archives that are readily accessible via the WWW for scientific analysis and research. For most of these Archives, the data they contain are becoming publicly available after a short period of proprietary time.

Most observatories are currently distributing Principal Investigator data to their user communities after the proprietary period has expired. This enables the scientific utilisation of these data for completely different purposes than the ones of the original proposer, and thus optimises the scientific return of observation infrastructure. But the distribution method is quite variable, from distribution on demand to full on-line archives with sophisticated data retrieval tools.

Observatories and organizations such as ESO, ESA, PPARC, CNRS and Jodrell Bank have invested telescope time and financial resources in producing archives with the potential to be reutilized for a variety of scientific purposes. The AVO offers the opportunity to federate these resources and provide astronomers with access to an integrated multi-wavelength repository of data for data mining and enabling new science.

Astronomical archives are potential a valuable teaching tool for school and university students. ESO and ESA have received funding for education purposes through the European Week for Scientific and Technological Culture Program. Through these efforts ESO has realized the magnitude of the potential utilization of archives by teachers and students. By enabling uniform and interactive access to distributed data archives, the AVO will provide an environment in which the public can participate in exploring the digital cosmos and in which teachers can build new educational resources.

A basic issue to be addressed during the initial phases of the AVO design is the uniformity in the quality of the data. Different Archives and, within them, data from different telescopes and instruments, have adopted different quality control procedures and indicators. The issue is particularly acute for the data collected by individual PI (Principal Investigators) that become public after the expiration of the proprietary period. The first step in addressing this issue is a review of the scientific quality of the existing Archives and the drafting of the scientific requirements for the standard quality control procedures to be adopted by Archives that want to be part of the AVO. The study will proceed by defining a set of quality indicators that are suitable for use by automatic querying and browsing systems. In some cases, the production of higher level Archive products (metadata or specific survey products) will be suggested and implemented.

Blast from the past, when oceans could be worked upon without having to worry about politics: the World Ocean Circulation Experiment (WOCE) 1990 – 2002 (including an appropriate data quality control process)

The WOCE Hydrographic Programme Office in Woods Hole was the first WOCE Data Assembly Centre (DAC) to be established (in 1990). Three years on we can look at how well we are doing. WHPO ‘data’ is digital data of either station locations and times or CTD and bottle data. These data with their attendant documentation come from PIs and at the end of the WHPO involvement are transferred to the WHP Special Analysis Centre (SAC) in Hamburg. After the proprietary period is over, data are made available to the WOCE community on an ftp server. The start of the path is the submission to WHPO of data sets and documentation by individual Chief Scientists. The WHPO usually re-formats the data and, in some cases, generates information files that are not otherwise available. Data are then sent out to a Data Quality Evaluator (DQE) for independent assessment of the quality. In the case of some repeat hydrography cruises, we hold a data set until we receive another one from the same group since it is as easy for a DQE to evaluate two data sets in the same region as one. Once the DQE reviews are complete, they are sent to the Chief Scientist, who is asked to revise his data set, (usually only by changing data flags or submitting additional information). The revised data set is re-submitted and, after further checking at the WHPO, is sent on to SAC and made publicly available once the proprietary period of 2 years elapses.

In fact this is what the WOCE home page shows:

The WOCE data set is the most comprehensive data set ever collected from the global ocean.This site provides access to the final (3rd) Version of the data set collected during the World Ocean Circulation Experiment (1990-1997).

How about the Hubble Space Telescope (where we are told what NASA does when it’s not climate in the picture)

In accordance with NASA policy, all science data from the Hubble Space Telescope is archived with a one-year proprietary period by default. This period may be extended or shortened at the request of the principle investigator (PI) and on approval by the STScI Director’s Office. Calibration data (i.e., data obtained under calibration proposals), by default, carries no proprietary period; neither does engineering data, calibration files (derived from calibration observations), and observatory monitoring data.

In addition to the regular proprietary period, observations by General Observers (GOs) which are found to be duplicates of concurrent observations by a Guaranteed Time Observer (GTO) may be placed under restriction. Data under restriction (or “embargoed”) cannot be distributed to the GO until the restriction expires (usually, when the GTO data goes public).

How easy is it, to get a Proprietary Rights Modification? Not much:

Requests for proprietary rights modifications (extensions, reductions, and/or restrictions) should be sent to the archive hotseat (archive@stsci.edu). The hotseat staff will forward all requests to the appropriate authorizing officials. All requests must be approved by the Director’s Office before being enacted.

More at the Space Telescope Science Institute, details about the “Extention of Proprietary Data Period”:

While individual images of my target will have some value, the scientific goals of this program are possible only when the entire dataset has been collected. I am now requesting that the proprietary data period be set to run from the completion of the last visit in the set. The timing on this request is important since your answer will greatly impact the upcoming budget submission.

Requests for non-standard proprietary data periods are unusual and are granted only in exceptional circumstances. Such a request should be addressed to Duccio Macchetto as the Associate Director for Science Policy.

And finally…on 14 April 2010, Nature magazine hosts a protest against “Telescope team may be allowed to sit on exoplanet data“:

on Monday a NASA advisory panel recommended that Kepler be allowed to censor 400 “objects of interest” — presumably good planet candidates — until February 2011, giving the mission team more time to firm up discoveries, rule out false positives and publish. If enacted, the new policy would represent a selective editing of data on the basis of its science content, rather than its quality — unprecedented for such NASA missions.

Many astrophysics programmes allow researchers a proprietary period with the data. For instance, guest observers on the Hubble Space Telescope get exclusive use of their data for a year before public release. But the tradition for NASA Discovery missions — small, principal-investigator-led missions like Kepler — is to make calibrated data available immediately. That policy has already been changed once for Kepler, last year, when the team was given more than a year to pursue confirmations and work out the kinks in its data processing.

Exoplanet astronomers outside the mission, however, are critical of what they say is an overly cautious approach. Scott Gaudi, an astronomer at Ohio State University in Columbus, says external astronomers might help the Kepler team, as it will be unable on its own to follow up and confirm all its candidate planets. “I think Kepler is being far too conservative, and far too closed about what’s going on,” he says, “and I think it’s to the detriment of science”.

[Malcolm] Fridlund, who is ESA’s study scientist for a planned follow-up planet-hunting mission called PLATO (Planetary Transits and Oscillations of Stars), wants to do things differently next time. The policy for the future mission will require the immediate dissemination of data. “You get a larger community and you get a bigger workforce for free,” he says. “It’s clear that the more people you get involved, the more support you get.”

 

Climategate: Stones That Should Be Left Unturned?

Anybody in need of yet more investigations? Over at DotEarth, there’s a Greenpa Minnesota (comment #20) clamoring for the hackers’ blood (figuratively speaking):

This time, kiddies- it is time for us scientists to DEMAND an EQUAL investigation be made into the identities of the hackers. I am dead serious. We need to demand it- loudly and publicly, and KEEP demanding until the FBI and similar world organizations are directed to do it.

But few if anybody at UEA are pushing for the hackers to be identified. The reason for such distinctively peculiar behavior is anybody’s guess.

Perhaps some stones are better left unturned…

…just as in the case of Kevin Trenberth, quoted by Roger Pielke Jr (comment #21) with words as pleasant as nails scratching a blackboard, including a reference to “unjustified criticisms and the widespread abuse and misuse of the emails” (no wonder some think AGW activism is ultimately an attack on civil liberties), and a mention of “lazy skeptics who want only to disprove the results“, a surefire candidate for the most childish opinion of the decade.

CRU Who? Or…Can The IPCC Survive The Oxburgh Review?

Forget Phil Jones and the CRU…for all intents and purposes, Lord Oxburgh’s “International Panel” has hit the IPCC itself with quite a broadside.

This is what the friendly Panel has just deemed necessary to write about the IPCC (my emphasis):

Recent public discussion of climate change and summaries and popularizations of the work of CRU and others often contain oversimplifications that omit serious discussion of uncertainties emphasized by the original authors. For example, CRU publications repeatedly emphasize the discrepancy between instrumental and tree-based proxy reconstructions of temperature during the late 20th century, but presentations of this work by the IPCC and others have sometimes neglected to highlight this issue. While we find this regrettable, we could find no such fault with the peer-reviewed papers we examined

And here’s what the IPCC says about the IPCC (my emphasis again):

The Intergovernmental Panel on Climate Change is the leading body for the assessment of climate change, established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) to provide the world with a clear scientific view on the current state of climate change and its potential environmental and socio-economic consequences.

Clearly, it has now been established beyond all doubt that the IPCC has been a failure regarding the provision of “a clear scientific view” on the “peer-reviewed papers” by CRU researchers. Those papers said one thing, the IPCC another.

With Climate Change too serious an issue to be left in oversimplifying hands,  the Fifth Assessment Report is unlikely to be any good unless substantial organizational changes are implemented in the IPCC.

A continuous struggle…

Reality is causing the Global Warming consensus to melt and what remains is thinner and more treacherous. AGWers need the consensus to hunt so they are having to travel further and further to reach their prey. As the consensus melts the area is also opened up to proper debate and free discussion and scientific exploration adding independent thinking to the many threats the AGWers already face.

Adult AGWer with two members of the public (AGWers-in-the-making)

Did you know…

…AGWers shelter the public from independent thinking in the safety of their “the debate is over” dens when they go hunting for skeptics. But as the consensus melts, these dens are collapsing – leaving the public vulnerable to skepticism and exposed to extreme discussion conditions.

…experts predict that Global Warming consensus could disappear completely in summer by 2011.

AGWer adoption/gift/present pack

Adopt an AGWer today…

…by adopting an AGWer you can help us save the AGWer and its home from the effects of reality and free discussion.

We must act now to try and save the AGWer from extinction.

ClimateGate: Had It Been For AGW Believers, Enron Would Still Be In Business

Professor Trevor Davies, Pro-Vice Chancellor for Research and Knowledge Transfer of the UEA, quoted yesterday by Willis Eschenbach in a comment to his “Freedom of information, my okole…“:

The University [of East Anglia, home of the CRU] takes its responsibilities under the Freedom of Information Act 2000, Environmental Information Regulations 2004, and the Data Protection Act 1998 very seriously and has, in all cases, handled and responded to requests in accordance with its obligations under each particular piece of legislation.

Kenneth Lay answering an analyst’s question on August 14, 2001, as quoted in Wikipedia:

There are no accounting issues, no trading issues, no reserve issues, no previously unknown problem issues. I think I can honestly say that the company is probably in the strongest and best shape that it has probably ever been in.

Willis vs. The CRU: A History of (FOI) Evasion

(a guest blog by Willis Eschenbach, originally posted to the Climate Sceptics mailing list. Published almost completely as-is).

An excerpt for those without time to read it all

the issue is not Trenberth or scientists talking smack. It is the illegal evasion of legitmate scientific requests for data needed to replicate a scientific study. Without replication, science cannot move forwards. And when you only give data to friends of yours, and not to people who actually might take a critical look at it, you know what you end up with? A “consensus” …

Freedom of information, my okole…
by Willis Eschenbach

People seem to be missing the real issue in the CRU emails. Gavin over at realclimate keeps distracting people by saying the issue is the scientists being nasty to each other, and what Trenberth said, and the Nature “trick”, and the like. Those are side trails. To me, the main issue is the frontal attack on the heart of science, which is transparency.

Science works by one person making a claim, and backing it up with the data and methods that they used to make the claim. Other scientists attack the work by (among other things) trying to replicate the first scientist’s work. If they can’t replicate it, it doesn’t stand. So blocking the FOIA allowed Phil Jones to claim that his temperature record (HadCRUT3) was valid science.

This is not just trivial gamesmanship, this is central to the very idea of scientific inquiry. This is an attack on the heart of science, by keeping people who disagree with you from ever checking your work and seeing if your math is correct.

Orders Countermanded, Comrades! Strong El Nino Is Good For You!

Thus spoke Bill Patzert, an oceanographer and climatologist at NASA’s Jet Propulsion Laboratory, Pasadena, California on Sep 28. 2009:

A macho El Niño like that of 1997-1998 is off the board, but I’m hoping for a relaxation in the tropical trade winds and a surprise strengthening of El Niño that could result in a shift in winter storm patterns over the United States. If the trade winds decrease, the ocean waters will continue to warm and spread eastward, strengthening the El Niño. That scenario could bring atmospheric patterns that will deliver much-needed rainfall to the southwestern United States this winter. If not, the dice seem to be loaded for below-normal snowpacks and another drier-than-normal winter…Don’t give up on this El Niño. He might make a late break and put his spin on this fall and winter’s weather systems

Wait a moment…so now a non-weak El Niño is good? Is this the first time anybody has said anything positive about El Niño?

No, it isn’t. Still, the ENSO has often been described as some kind of scourge. For example, here’s an article from The Independent on Jan 1, 2007:

A combination of global warming and the El Niño weather system is set to make 2007 the warmest year on record with far-reaching consequences for the planet, one of Britain’s leading climate experts has warned.

Professor Jones said the long-term trend of global warming – already blamed for bringing drought to the Horn of Africa and melting the Arctic ice shelf – is set to be exacerbated by the arrival of El Niño, the phenomenon caused by above-average sea temperatures in the Pacific.

The WMO said its latest readings showed that a “moderate” El Niño, with sea temperatures 1.5C above average, was taking place which, in the worst case scenario, could develop into an extreme weather pattern lasting up to 18 months, as in 1997-98. The UN agency noted that the weather pattern was already having “early and intense” effects, including drought in Australia and dramatically warm seas in the Indian Ocean, which could affect the monsoons. It warned the El Niño could also bring extreme rainfall to parts of east Africa which were last year hit by a cycle of drought and floods

And from a brochure published the UK’s Met Office in Nov 2006:

Dry spells are not unusual in the Amazon, but normally occur in El Niño years.

[…] the large number of Indonesian fires and associated increase in carbon emissions during the 1997-1998 El Niño event

And the IPCC (TAR)? Here it is:

El Niño is associated with dry conditions in northeast Brazil, northern Amazonia, the Peruvian-Bolivian Altiplano, and the Pacific coast of Central America. The most severe droughts in Mexico in recent decades have occurred during El Niño years, whereas southern Brazil and northwestern Peru have exhibited anomalously wet conditions

More recently, from the IPCC’s AR4, WG2, chapter 1:

After the accelerated shrinkage of the glacier during the 1990s, enhanced by the warm 1997/98 El Niño, Bolivia lost its only ski area
