Minutes after Donald Trump took office as President, the page on climate change of the website of the White House disappeared. This may be just a result of some internal protocol, but also the first stage of a coming "purge" of climate science and climate scientists. In any case, the election of Trump is a major defeat for science and we need to understand what mistakes we made to arrive at this point. I am writing here something that probably won't make me popular with my scientist colleagues, but I thought I had to write it.
Defeats are supposed to teach people how to do better; in theory. In practice, it often happens that defeats teach people how to become masters in blame-shifting. With some exceptions, this seems to have been the main result of the recent defeat of the Democrats in the 2016 presidential election, where we saw a truly spasmodic search for culprits: Putin, the Russian hackers, the Fake News, the Rednecks, the FBI, Exxon, the aliens from Betelgeuse, and more. Everything except admitting one's mistakes.
Even less soul searching has been performed by those who turned out to be among the major losers in this story: science and scientists. In particular, climate scientists saw their field wiped out from the White House Website minutes after President Trump took office. That may have been simply a question of protocol, but surely it is not a good omen for the future.
So far, scientists have reacted with appropriate outrage to possibilities such as Trump repudiating the Paris climate treaty. However, on the average, scientists seem to be completely unable to even imagine that there may be something wrong with what they have been doing. We may have here a good illustration of the principle expressed by James Schlesinger that "people have only two modes of operation: complacency and panic". Even though some scientists are starting to show symptoms of panic, most of them seem to be still in complacency mode.
Yet, for everything that happens there is a reason and if you invaded Russia in winter it is no good to blame the snow for the defeat. So, what did scientists do that led them to a situation that may turn out to be even worse than the retreat from Moscow for Napoleon's Grande Armée?
One problem, here, is that if scientists had wanted to present themselves to the public as a priesthood of acolytes interested only in maintaining their petty privileges, they succeeded beyond the rosiest expectations. Yet, I don't think that this is the problem. Overall, science is still a sane profession and very few scientists have been directly involved in financial scandals. The public perceives this and normally rates scientists as much more trustworthy than - say- journalists or politicians. And modern climate science, as part of the field of Earth sciences, is nothing less than a triumph of human knowledge. Truly a major advance of what we know on the way our planet and our ecosystem work.
The problem, in my opinion, is a different one. It goes deeper and it is not related to individual scientists or to specific scientific fields. It has to do with science as a whole and, in particular, with the inconsistent messages that scientists are beaming to the public. According to the results reported by Ara Norenzayan's in "Big Gods" (Princeton, 2013), people have a built-in "lie detector" in their minds that works by a heuristic algorithm: people will evaluate the truth of what they are told on the basis of consistency. Not only the message must be consistent in itself, but also the messenger must be consistent with the message carried. This is a fundamental point: people don't normally care about data and factual evidence: they care about the consistency of the message in their social environment; it is something that Dan Kahan has shown in a series of studies on the public perception of climate science.
So, if your local prophet tells you that you must be chaste, he'd better be chaste himself. If he tells you that you must make sacrifices and accept poverty, he'd better be poor himself. And chastity/poverty must be acceptable in your social environment. These are things that Francis of Assisi understood already long ago. Then, think of Donald Trump: why was he elected? It was, mainly, because Trump's political message was consistent with Trump himself. Trump was telling people that he would make America rich and powerful and that was perfectly consistent with the fact that he is rich and powerful himself. Because of this, Trump's message didn't trigger people's lie detector and Trump the unthinkable became Trump the unavoidable.
Getting back to science, the message of climate change is intimately linked to the need of making sacrifices. We are asking people to reduce their consumption, reduce waste, travel less, and the like. It is a perfectly legitimate message and many religious groups have been carrying similar messages successfully. Of course, it would never work if Donald Trump were to propose it; but why can't scientists propose it successfully? Scientists are not Franciscan monks, but normally they are not rich. I often tell my PhD students that they are exchanging three years of starvation for a lifetime of unemployment. I don't really need to tell them that: they know that by themselves.
The problem is that there exists another side of science where scientists are beaming out exactly the opposite message of that of the need of making sacrifices. It is the side of the "gee-whiz science" or, maybe, "Santa Claus Science", scientific research still operating along the optimistic ideas developed in the 1950s, at the time of the "space age" and the "atomic age". The message that comes from this area is, "give us some money and we'll invent some magic device that will solve all the problema." It is a message that's ringing more and more hollow and the public is starting to perceive that the scientists are making promises they can't maintain. Not only the various scientific miracles that were promised are not materializing (say, nuclear fusion) but many pretended scientific revolutions are making things worse (say, shale oil). Still, many scientists keep making these promises and a certain section of society accepts - even requires - them.
So, the name of the problem is inconsistency. Scientists are taking two different and incompatible roles: that of doom-sayers and that of gift-givers. And "inconsistency" is just a polite way to say "lie." White scientist speak with forked tongue. Ye can't serve God and mammon.
The result is that not just Donald Trump despises science; it is a consistent fraction of the public that just doesn't believe the scientific message, especially about climate. The fraction of Americans who think that climate change is a serious threat has remained floating around 50% - 60%, going up and down, but not significantly changing. It is trench warfare in the climate communication war. Things may get worse for science under the Trump presidency. It already happened at the time of McCarthy, why shouldn't it happen again?
At this point, good manners dictate that when you write about a problem, you should also propose ways to solve it. Of course, there are ways that could be suggested: first of all, as scientists we should stop asking money for things that we know won't work (the "hydrogen-based economy" is a good example). Then, science badly needs a cleanup: we should crack down on predatory publishers, fight data fabrication, establish transparent standards for scientific publications, provide for free results of science to those who pay for it (the public), get rid of the huge number of irrelevant studies performed today, and more. Personally, I would also like a science that's more of a service for the community and less of a showcase for primadonnas in white coats.
But, as we all know, large organizations (and science is one) are almost impossible to reform from inside. So, where is science going? Difficult to say, but it may need a good shake-up from the outside (maybe from Trump, although he may well exaggerate) to be turned into something that may be what we truly need to help humankind in this difficult moment. The transformation will be surely resisted as much as possible, but change is needed and it will come.
"No man can serve two masters: for either he will hate the one, and love the other; or else. he will hold to the one, and despise the other. Ye cannot serve God and mammon." (Matthew 6:24)
