Response to Richard @ BH

In response to the comments by Richard on this thread.

Sean Houlihane The practice of hiding the detail of a method is (and was admitted by Jones) not beneficial in the sense that a robust theory can look after itself. Transparency in the method will improve the method. This is not really a matter for sensible argument (and that was the IoP’s submission)

NOT BENEFICIAL??? IMPROVE THE METHOD??!! WHAT ON EARTH ARE YOU TALKING ABOUT?

How can a theory be “robust” when the “detail of the method” is hidden? When that happens “the theory”, (read temperature trends), are not worth the paper they are written on, much less the basis on which to commit trillions of dollars of public money, shutting down our power generating infrastructure and moving us back to the stone age.

Stop for a moment and read what I intended to write, not what you think I wrote. I can see no logical argument which supports Gavin’s position that the secrecy is justified. Gavin says that providing more open access to the data and the method is risky because it might be abused. I say that if, and only if the theory happens to be correct as many people for various reasons believe then it can look after itself. At a scientific level, there is a need for as good a temperature series as is possible – this is how we justify having satellites and collations of instrumental data.

Not much new is known to suggest that the data is any different now compared with 6 months ago.

True but what is now known is that data is crap.

Not proven. In order to argue this, you need to be specific about which data and why you believe it is crap. Is Roy Spencer’s data contaminated by the problems you don’t elaborate on? Would you claim that the last 10 years might have seen strong warming? The only data issue I could imagine being affected by recent events is the question about comparing today’s temperatures with the MWP (and there the answer could be ‘maybe’ rather than ‘almost certainly not’)

No alternative temperature reconstructions have yet been accepted as moving the science forward, so the evidence is unchanged.

Because the bloody thick headed stupid deniers, or those who are crooked and willing to sell our future for 40 pieces of silver, will never accept the abundant temperature reconstructions which show that todays warming is in no way unique!

Too many variables. I was thinking of 1850-2010 temperatures, which are sufficient evidence for many who claim that something must be done. Go back to 1000, and the uncertainties are too large. Go back further, and the continents were not in the same place. Progress is being made, people are looking, but there is an abundance of short term environmental evidence that change is occurring which scares many people who imagine we might be at fault.

.The quality of the evidence is in question, but not by enough to justify a change in policy.

Its just a smidgen less is it? What would be enough to wake the warmists from their brain dead stupor?

You’ve got the logic back to front. Go back 30 years, and you’ll find a group of people with concerns about ozone, heavy metals, energy dependence, overpopulation, clean water, food and rain forests. They have seen the AGW issue as being aligned with their ideologies, and will take every possible fragment of supporting evidence to further their cause. They are scared, and even if this is irrational, it will take more than some scientific wrangling to convince them that the policies they support are either impractical or have significant un-intentional consequences. Try talking to a wamist about the relative costs of microgeneration and nuclear power for example.

This question is unrelated to the original submission from the IOP – they have not yet bothered to re-assess the scientific basis for current policy. It is not that they don’t care, it is not as simple an issue as ‘should the data be freely available‘.

. I can’t fail to see comments such as ‘Richard’ as being the cause for the IOP having to issue a clarification. I am disappointed that there are veiled accusations of bias being made here.

Bias? The managing committee issues a statement “The institutes position on climate change is clear: the basic science is well enough understood to be sure that our climate is changing, (changing? bloody hell – who would have known) and that we need to take action now to mitigate that change.”

The IoP has taken what you interpret as a biased position for many years. My issue was with this

This is very interesting. I think I follow developments on the climate front as closely as anyone, but I can’t say I’ve heard anyone suggest that the IoP was saying anything more than it actually did – that the climategate affair had worrying implications for the integrity of climatology.

In these circumstances, one also wonders who it was that “forced” the IoP to issue a clarification.

The forcing of the issue was fairly clear to me, the various contributors to the comment threads who were claiming that ‘this means it’s all over’. All they said was the behaviour of this one group of scientists did not meet the standards they had assumed.

When some in the Institute of Physics state that the integrity of scientific research in the climate science field is in doubt and its credibility of their use of the scientific method is in question, how on earth can the managing committe state that we need to take action to mitigate that change? How will that action be any more effective than throwing rice over your shoulder or doing a rain dance? Just because it will cost trillions of dollars more?.

The IoP has taken a clear position on the climate change/response issue for several years. Some of this is motivated by their interest in high energy physics, and some seriously expensive research going into using fusion for power generation, solar generation, efficient lighting technology. Some of it is motivated by an academic membership with personal opinions. Regardless of how stupid you feel these policies are, they were derived over a period of time based on the current understanding of the time. I’m not sure how you would want them to update their policy?

Should they say that change is not happening?
Should the focus be on adapting to the inevitable changes?
Should we just ignore it all and carry on regardless?
Should we assume CO2 is not a problem and focus on sustaining a larger population?
Should research focus on long term cost efficiency?
Maybe they will discuss questions like this, on the assumption that the IPPC reports are complete fabrication, or maybe they will turn their attention instead to asking how to improve the science. That is a question for the next 6-12 months at least, and is not covered in any way by the scope of their submission to the CRU leak inquiry.

Institute of Physics submission to CRU Inquiry

I was meaning to write about this when the story first appeared on 28th Feb of the IoP making a very forceful submission to the Science and Technology committee’s inquiry into the data disclosure (climategate emails). The submission is very strong on the behavior of the scientists and their actions which appeared to make replication and verification of the temperature series and proxy reconstructions impossible. The submission was highlighted by ClimateAudit, WattsUpWithThat and BishopHill, where some of the contributors seemed to read it as saying that this was final acceptance that the science was a sham.

Whilst RealClimate don’t have a seperate thread, their refutation is pretty entertaining – they seem to struggle to work out who the Institure of Physics are to start with, then accuse them of being industry led (actually, they seem to be a predominantly academic organisation, and have printed many many articles in Physics World lamenting the fact that the planet is doomed). RealClimate site responses (from the ‘real climate scientists’) are all on message, supporting the ‘standard practice’ of not releasing code.

By 2nd March (the day after the oral hearings, which recieved a good amount of media coverage), the IoP issues a clarification stating that their submission does not address the question of the consensus, and the Institute does not doubt that. Quite what has caused this is not clear, but there is certainly a severe mis-understanding regarding the principle of repeatability.

The view from RealClimate is that it is OK to keep the data secret, if it gets into the wrong hands it could be mis-used in a dangerous way, and anyway the process has been replicated independantely and shown to be good. Since people like Gavin speak from a modeling point of view, I can see some logic in saying that making the models open wouldn’t be much of an advancment of the science. (The code is probably ugly, there are several pseudo-independant models, and the models are not particularly precise anyway)

Frank O’Dwyer keeps repeating that open-access should apply to all, sceptics included, yet fails to accept that several people have been attempting to verify the methods used in several studies in order to check the methods. The accusation of (unintentional) selection bias in datasets, inapropriate adjustments to data series, manipulation of the peer review process, etc. are not issues which the skeptical community need to answer. Much of the interest is in series which to date show a fairly small degree of warming, so small errors are significant. Even if most users of the data only use it to confirm correlation with (e.g. hurricane disaster losses) there is a need to enable the reconstruction itself to be challenged. The various tree ring cronology questions which have been asked in the past show that if the reasons for selecting a specific series are secret, it rapidly becomes impossible to determine how robust a method is to being fed bad data.

Some commentors have argued that the IoP’s submission justify doing nothing, and that the precautionary principle is not applicable to the climate change scenario. it may be this reasoning which prompted the clarification. The precautionary principle theory goes along the lines of ‘even if it’s not proven for sure, we should react just in case it is important to start now’. All that has been expressed by the IoP is that the scientific method has not been sufficiently open. Extrapolating from that to say that the data we have should be thrown away, and we need not worry about anything is pure flat-earth territory. We have a number of facts, which justify a level of concern. Some of those facts have not been tested as well as an independent scientist might have assumed, but that is still the best case analysis to date. Some policies are still sensible, regardless of the need/desire to restrict CO2.

The IoP has said it is good to question the consensus, and to encourage critical analysis of the reconstructions. It should be enough for now to agree that more open access to the data and methods is a priority – a point which is still contested by many of the alarmist proponents. questions like UHI adjustments and divergence must be brought back to the table at the scientific/statistical level. This is a straightforward view which requires no judgment of value or personal priority, it is basic scientific process.

From a policy point of view, there are many things changing. The datasets are slowly growing, agreement with model projections is decreasing, trends are changing, the independence of the consensus position is coming under question. The validity of some of the data has a very small influence on this today. It is likely that people will become less prepared to support expensive measures in the short term, but it is best to assume that nothing will emerge to prove that the science is completely wrong.

Polar Bears thrive at the equator

Since we often see Polar Bears playing in the snow, I thought that it would be worth posting these pictures which I took at Singapore Zoo. This is just north of the equator, and it was cool when I was there, just below 30 degrees Celsius. To be clear, the polar bear does have somewhere cool to retire to, but seemed perfectly happy out in the sun.
