Nature has published a great article on the whole climategate tempest.
Here are the highlights:
The e-mail archives stolen last month from the Climatic Research Unit at the University of East Anglia (UEA), UK, have been greeted by the climate-change-denialist fringe as a propaganda windfall (see page 551). To these denialists, the scientists’ scathing remarks about certain controversial palaeoclimate reconstructions qualify as the proverbial ‘smoking gun’: proof that mainstream climate researchers have systematically conspired to suppress evidence contradicting their doctrine that humans are warming the globe.
This paranoid interpretation would be laughable were it not for the fact that obstructionist politicians in the US Senate will probably use it next year as an excuse to stiffen their opposition to the country’s much needed climate bill. Nothing in the e-mails undermines the scientific case that global warming is real — or that human activities are almost certainly the cause. That case is supported by multiple, robust lines of evidence, including several that are completely independent of the climate reconstructions debated in the e-mails.
And in regards to the FOI requests (the most damaging revelation from the emails in my opinion):
If there are benefits to the e-mail theft, one is to highlight yet again the harassment that denialists inflict on some climate-change researchers, often in the form of endless, time-consuming demands for information under the US and UK Freedom of Information Acts. Governments and institutions need to provide tangible assistance for researchers facing such a burden… But for much crucial information the reality is very different. Researchers are barred from publicly releasing meteorological data from many countries owing to contractual restrictions. Moreover, in countries such as Germany, France and the United Kingdom, the national meteorological services will provide data sets only when researchers specifically request them, and only after a significant delay. The lack of standard formats can also make it hard to compare and integrate data from different sources. Every aspect of this situation needs to change: if the current episode does not spur meteorological services to improve researchers’ ease of access, governments should force them to do so.
The biggest problem with being open is that much of the systems in place to ensure openness assume that those seeking the data are looking at the issue honestly. Because of this, there is little in the way of safe guards for abuse by those who are not interested in an honest look at the data, but instead in wasting time and finding anything (no matter how insignificant) that can be spun in a damaging light.
Steve Easterbrook sums up the problems with openness very well. Saying: “A significant factor in the reluctance of climate scientists to release code and data is to protect themselves from denial-of-service attacks. There is a very well-funded and PR-savvy campaign to discredit climate science. Most scientists just don’t understand how to respond to this. Firing off hundreds of requests to CRU to release data under the freedom of information act, despite each such request being denied for good legal reasons, is the equivalent of frivolous lawsuits. But even worse, once datasets and codes are released, it is very easy for an anti-science campaign to tie the scientists up in knots trying to respond to their attempts to poke holes in the data. If the denialists were engaged in an honest attempt to push the science ahead, this would be fine (although many scientists would still get frustrated – they are human too).
But in reality, the denialists don’t care about the science at all; their aim is a PR campaign to sow doubt in the minds of the general public. In the process, they effect a denial-of-service attack on the scientists – the scientists can’t get on with doing their science because their time is taken up responding to frivolous queries (and criticisms) about specific features of the data. And their failure to respond to each and every such query will be trumpeted as an admission that an alleged error is indeed an error. In such an environment, is it perfectly rational not to release data and code – it’s better to pull up the drawbridge and get on with the drudgery of real science in private. That way the only attacks are complaints about lack of openness. Such complaints are bothersome, but much better than the alternative.
In this case, because the science is vitally important for all of us, it’s actually in the public interest that climate scientists be allowed to withhold their data. Which is really a tragic state of affairs. The forces of anti-science have a lot to answer for.”
And Robert Grumbine has an excellent post on the difficulties of data set reproducibility that is will worth a read. Suffice to say that none of this is trivial, and there are many non-nefarious reasons why CRU wasn’t 100% open.
In the end Nature sees no reason to investigate any of the papers it has published, because it sees nothing that compromises the science.
The stolen e-mails have prompted queries about whether Nature will investigate some of the researchers’ own papers. One e-mail talked of displaying the data using a ‘trick’ — slang for a clever (and legitimate) technique, but a word that denialists have used to accuse the researchers of fabricating their results. It is Nature‘s policy to investigate such matters if there are substantive reasons for concern, but nothing we have seen so far in the e-mails qualifies.
Oh and also it turns out that scientist are human, not emotionless Vulcans.
In the end, what the UEA e-mails really show is that scientists are human beings — and that unrelenting opposition to their work can goad them to the limits of tolerance, and tempt them to act in ways that undermine scientific values. Yet it is precisely in such circumstances that researchers should strive to act and communicate professionally, and make their data and methods available to others, lest they provide their worst critics with ammunition. After all, the pressures the UEA e-mailers experienced may be nothing compared with what will emerge as the United States debates a climate bill next year, and denialists use every means at their disposal to undermine trust in scientists and science.
But we already knew that. Now where did I leave that teapot?
