The blog discussion of the week seems to be about IPCC’s Special Report on Renewable Energy Sources and Climate Change Mitigation. Question is, has a study headed by a Greenpeace employee been overly hyped? I think the short answer is that it has in the press release but it hasn’t in the underlying report.
One would think that that would be the end of it. It’s become the norm that press releases highlight an eye catching finding rather than trying to paint a full picture of the underlying report. The former draws media attention; the latter does not. Media need a news hook after all, as we’re frequently told by journalists. That’s not necessarily a good thing for science journalism and science literacy, but it’s the case nevertheless.
Then why does the bulk of the criticism go to the whole of the IPCC process? That’s a bit of a rhetorical question of course, as the answer is fairly obvious: There are legions of people looking for excuses to throw the IPCC under the bus. And sometimes even people who have a decent understanding of the issues are enclined to support such efforts, if they become convinced of serious wrongdoing. Think Monbiot with regards to “climategate” and now Mark Lynas with the SRREN. Mind you, I think the questions that Lynas posed to the IPCC are fair and deserve to be answered:
Here, repeated, are the questions I have posed to the IPCC’s Edenhofer:
1: what was the process for writing the press release, and who decided whether it faithfully represented the main conclusions of the SPM/main report?
2: why was the SPM released more than a month before the full report?
3: was Sven Teske in any way involved in the decision to highlight Teske et al, 2010 as one of the four ‘illustrative scenarios’ explored in greater depth as per Section 10.3.1?
4: what is the IPCC conflict of interest policy with regard to lead authors reviewing their own work, and having affiliations to non-academic institutions, whether campaign groups or companies?
The Carbon Brief has a good rundown of issues. One paragraph though struck me:
the use of word “could” in the IPCC’s press release (“Close to 80 percent of the world’s energy supply could be met by renewables by mid-century”) is likely to refer to future uncertainties, but may well have been perceived by journalists and the public as a straightforward statement about the technical potential of renewable energy.
I think it’s the opposite: I think the word “could” refers to “technical potential” rather than to future uncertainties. As in, if we really wanted to and put the effort (and money) in, this is what we could achieve. Whereas most reading this understand it in the other way and then interpret is as hopelessly optimistic and biased.
I agree that it’s not wise to put a rather unrealistic scenario forward as an example in the spotlights. My point is not so much to argue how silly vs wise, or how realistic vs unrealistic is it, but rather to distinguish that which is technically possible from what is societally and politically realistic. David Keith (in a different context) made some pertinent comments to this:
However when people and the political community hear technical people say “can’t be done” they assume we mean that technically can’t be done and that is untrue and destructive.
It’s destructive because it hides the central moral choice: we could cut emissions if we want to, we could have started decades ago when the scientific warnings about climate change were first raised, but we decided not to. It was a choice, implicit or not. A choice that, in effect, we cared more about current consumption than we did about preserving our grandchildren’s chances to enjoy a climate like the one in which our civilization developed.
McIntyre, in a comment at DotEarth, seems to agree that the central issue is the press release:
Andy, I don’t think that you adequately highlighted that the Greenpeace scenario was the one that was featured in the IPCC press release and covered by the world media. Had the problem been limited to the Chapter 10 discussion, it would be less of an issue.
Which leads Michael Tobis to remark:
It does appear that whoever wrote the press release did a disservice. This seems so common in press reports of science that I am starting to think of it as typical. If Mr. McIntyre had limited himself to such a claim, as he does here, I would have no quarrel with his behavior in this case. But he proceeds, on his blog, to use this incident to call for “Everyone in IPCC WG3 [to] be terminated and, if the institution is to continue, it should be re-structured from scratch.”
Thus he continues to play to the “climate science as fraud” crowd that frequents his blog while adopting a more reasonable pose here.
The persistent substitution of fake problems for real ones is a key to derailing serious conversations these days.
The important conversation that we should be having, connected with the issues in the SRREN, is about what kind of future we want.
