RealClimate's message to the media: It's your responsibility “to actually investigate whether allegations have any merit”

In a February 14 post, the climate scientists at RealClimate.org addressed the media coverage of recent allegations that errors in the IPCC's 2007 report discredit the UN panel and undermine climate science:

To those familiar with the science and the IPCC's work, the current media discussion is in large part simply absurd and surreal. Journalists who have never even peeked into the IPCC report are now outraged that one wrong number appears on page 493 of Volume 2. We've met TV teams coming to film a report on the IPCC reports' errors, who were astonished when they held one of the heavy volumes in hand, having never even seen it. They told us frankly that they had no way to make their own judgment; they could only report what they were being told about it. And there are well-organized lobby forces with proper PR skills that make sure these journalists are being told the “right” story. That explains why some media stories about what is supposedly said in the IPCC reports can easily be falsified simply by opening the report and reading. Unfortunately, as a broad-based volunteer effort with only minimal organizational structure the IPCC is not in a good position to rapidly counter misinformation.

One near-universal meme of the media stories on the Himalaya mistake was that this was “one of the most central predictions of the IPCC” - apparently in order to make the error look more serious than it was. However, this prediction does not appear in any of the IPCC Summaries for Policy Makers, nor in the Synthesis Report (which at least partly explains why it went unnoticed for years). None of the media reports that we saw properly explained that Volume 1 (which is where projections of physical climate changes belong) has an extensive and entirely valid discussion of glacier loss.

What apparently has happened is that interested quarters, after the Himalyan glacier story broke, have sifted through the IPCC volumes with a fine-toothed comb, hoping to find more embarrassing errors. They have actually found precious little, but the little they did find was promptly hyped into Seagate, Africagate, Amazongate and so on. This has some similarity to the CRU email theft, where precious little was discovered from among thousands of emails, but a few sentences were plucked out of context, deliberately misinterpreted (like “hide the decline”) and then hyped into “Climategate”.

As lucidly analysed by Tim Holmes, there appear to be a few active leaders of this misinformation parade in the media. Jonathan Leake is carrying the ball on this, but his stories contain multiple errors, misrepresentations and misquotes. There also is a sizeable contingent of me-too journalism that is simply repeating the stories but not taking the time to form a well-founded view on the topics. Typically they report on various “allegations”, such as these against the IPCC, similar to reporting that the CRU email hack lead to “allegations of data manipulation”. Technically it isn't even wrong that there were such allegations. But isn't it the responsibility of the media to actually investigate whether allegations have any merit before they decide to repeat them?

Overall then, the IPCC assessment reports reflect the state of scientific knowledge very well. There have been a few isolated errors, and these have been acknowledged and corrected. What is seriously amiss is something else: the public perception of the IPCC, and of climate science in general, has been massively distorted by the recent media storm. All of these various “gates” - Climategate, Amazongate, Seagate, Africagate, etc., do not represent scandals of the IPCC or of climate science. Rather, they are the embarrassing battle-cries of a media scandal, in which a few journalists have misled the public with grossly overblown or entirely fabricated pseudogates, and many others have naively and willingly followed along without seeing through the scam. It is not up to us as climate scientists to clear up this mess - it is up to the media world itself to put this right again, e.g. by publishing proper analysis pieces like the one of Tim Holmes and by issuing formal corrections of their mistaken reporting. We will follow with great interest whether the media world has the professional and moral integrity to correct its own errors.

The RealClimate scientists single out the British media, but as Media Matters has repeatedly shown, American media outlets are more than willing to forgo serious evaluation of false and misleading claims about climate science. Indeed, today the Wall Street Journal editorial board asserted that IPCC's reports “are sloppy political documents intended to drive the climate lobby's regulatory agenda.” To support this claim, the Journal cited “news that an IPCC claim that global warming could destroy 40% of the Amazon was based on a report by an environmental pressure group.” The editorial further stated:

Take the rain forest claim. In its 2007 report, the IPCC wrote that “up to 40% of the Amazonian forests could react drastically to even a slight reduction in precipitation; this means that the tropical vegetation, hydrology and climate system in South America could change very rapidly to another steady state.”

But as Jonathan Leake of London's Sunday Times reported last month, those claims were based on a report from the World Wildlife Fund, which in turn had fundamentally misrepresented a study in the journal Nature. The Nature study, Mr. Leake writes, “did not assess rainfall but in fact looked at the impact on the forest of human activity such as logging and burning.”

In fact, as the RealClimate scientists explain in their post, the IPCC's statement on the sensitivity of much of the Amazonian forests is supported by peer-reviewed studies. And Daniel Nepstad, the author of several of these studies has stated that “the IPCC statement on the Amazon was correct,” a fact that never had a chance with readers of the Journal editorial. The IPCC citation was incomplete, but the “rain forest claim” itself was correct. This is the kind of information that a responsible media would provide.
