There are no breaking news at the moment


David Rose popularized the concept of the “pause” in global warming in a 2012 article on the Daily Mail. There never was such a thing, but it became a highly successful meme (*), still widely cited today as proof that global warming doesn’t exist or it is nothing to be worried about. By now, the rapid rising temperatures of the past few years should have been consigned the “pause” to the oblivion it fully deserves. But a group of scientists offered to Rose the occasion to double down and to accuse them of manipulating the data. 

Years ago, I used to play chess, even though I always remained, at best, at a low-medium skill level. Once, I found myself playing with a local high-level player and I was thoroughly trashed, quickly checkmated. I offered my congratulations to him and he answered to me with something like, “Ugo, it is not that I am especially good. It is you who made mistakes with your moves. Make no mistakes, and nobody will ever checkmate you.”

I think that was good advice that I still try to remember after many years. If you are defeated, it may be that your opponent is especially good, but it is also likely that he or she simply exploited your mistakes. Avoid making mistakes, and your life will be easier. But you need to recognize the mistakes you made and admit them.

This seems to be the problem with the present debate on climate science. Facing aggressive criticism, scientists keep making the most elementary communication mistakes. The latest disaster for science is the recent article by David Rose in which scientists are accused to be manipulating the data. Rose, you may remember, is the journalist who first diffused in the media the idea that there had been a “pause” in global warming. His 2012 article in the Daily Mail was a milestone in the meme war; with the “pause” (or “hiatus”) still widely known and repeated as “proof” that global warming doesn’t exist or that, at least, climate models don’t work (*).

Obviously, the “pause” never was anything more than a perfectly normal oscillation – amplified by carefully choosing a specific interval of temperatures. The recent temperature increases broke all the warming records and that should have buried forever the “pause”, together with other legends such as the claimed arrival of the planet Nibiru in 2012. But, no. Now David Rose doubles down with a new article in which he, this time, accuses scientists of having manipulated the data in order to make the pause disappear.

I don’t think I need to tell you that Rose’s latest article is a textbook example of logical inconsistency. First, he claimed the existence of the “pause” on the basis of temperature data that, evidently, he trusted. Now, he says that the data shouldn’t be trusted because they don’t show a pause. If there ever was an example of motivated reasoning, this is it.

Yet, communication is not just a question of formal logic. Take a tour of the Web and you’ll see how many people are gleefully commenting on Rose’s latest broadside against science. It is a landslide; the dam has given way: it is a true disaster for science. Maybe Rose is an evil genius in communication, but I think he is not. He is just exploiting the mistakes made by climate scientists.

This story is all about an article published in 2015 by a group of NOAA scientists who claimed that there is no evidence of a slowdown in the world’s temperature increase. The article was perfectly good in scientific terms, but it was a terrible mistake in terms of communication. Why? Because it ignored a simple fact of life: in the mass media debate, mentioning a concept, even if for debunking it, has the effect of reinforcing the public perception that the concept is real.

This is a well known concept. On this issue, you may read a good article by Chris Mooney describing the “backfire effect” or, sometimes, the “boomerang effect”. Among the many cases, it was found that having Barack Obama explicitly stating that he is not a Muslim tends to reinforce some people’s belief that he is. And you surely remember the story of the “weapons of mass destruction” in Iraq. There never was any proof for their existence (and, indeed, they never existed). But the more the subject was debated, the more people became convinced that they existed.

In the end, it is simple: debunking doesn’t work; on the contrary, it often reinforces the perception that the belief being debunked is true. So, it should have been obvious that a paper that attempted to demonstrate that there never was a “pause” would generate a backlash, one day or another. And it did.

Let me repeat: For what I can say, there is nothing wrong in scientific terms in the work by Karl et al. But place yourself in the shoes of a person who is not a scientist, won’t you get the impression that the scientists are fiddling with the data? That’s the point that the critics of science are making over and over and this message seems to be going through.

Maybe it was unavoidable that a review of the temperature data would lead to this result, but was it appropriate to publish a minor correction of a data set in a high-visibility journal? If it was in order to affect climate policies, it was a perfectly legitimate target, but only if based on rock-solid data. Didn’t the people involved in this work realize that their corrections are debatable, to say the least? And how is it that no one in NOAA thought that in some quarters the corrections would be understood and described as politically motivated data manipulation? Do scientists always have to be so naive?

Now, many scientists are trying to debunk Rose’s article (**), but the problem remains the same: the more you mention the “pause”, the more it becomes real for the public. And that’s a victory for the enemies of science. It seems that, as scientists, we are falling over and over into the same traps. As long as we do that, we’ll keep being checkmated by people who exploit our mistakes.

(*) About the power of the “pause” as a meme, note that even a Nobel prize in physics, Carlo Rubbia, became convinced that it was something real. You can hear him (in Italian) here saying that on minute 2.40 

(**) Note that climate scientists are debunking Rose who was debunking NOAA that was debunking Rose who was debunking climate scientists. Quite a trophic chain of debunking and counter-debunking. A true “metadebunking” that only confuses people and plays in the hand of the enemies of science.

  2. What Mr. Rose omitted however, is incredibly telling and he does a disservice to his readers.

    First, he neglects to mention that the work from the 2015 paper authored by Dr. Thomas Karl and others at NOAA has already been independently verified by other researchers.

    The second thing Rose neglects to mention is that his story’s source was never involved any part of the work. According to a colleague of the authors Peter Thorne, this source:never participated in any of the numerous technical meetings on the land or marine data I have participated in at NOAA NCEI either in person or remotely. This shows in his reputed (I am taking the journalist at their word that these are directly attributable quotes) misrepresentation of the processes that actually occurred. In some cases these misrepresentations are publically verifiable.

    Mr. Rose further neglects to mention that Dr. Karl was not involved in the development of the critical sea surface temperature data that was used in the study. That information was already published before the Karl paper appeared.
