The disconnect between The Wall Street Journal’s excellent coverage of climate change as a credible, man-made threat, and its editorial opinion that global warming is a lot of, well, hot air, is well established. This week, the opinion page seemed to be striving for a new level of myopia.
On Wednesday, Holman W. Jenkins, Jr., a member of the Journal’s editorial board, published a column reanimating the rapidly souring complaint that Al Gore doesn’t deserve a Nobel Peace Prize for “promoting belief in manmade global warming as a crisis.” Jenkins worries that journalists will credit Gore with an overstated achievement.
“The media will be tempted to blur the fact that his medal, which Mr. Gore will collect on Monday in Oslo, isn’t for ‘science,’” Jenkins wrote. He then lays out his belief that the much-heralded scientific consensus that humans are warming the planet is entirely artificial. Jenkins attributes the widespread belief in that consensus to the effect of an “availability cascade,” whereby an idea gains traction simply because the press repeats it:
What if the heads being counted to certify an alleged “consensus” arrived at their positions by counting heads? It may seem strange that scientists would participate in such a phenomenon. It shouldn’t. Scientists are human; they do not wait for proof; many devote their professional lives to seeking evidence for hypotheses (especially well-funded hypotheses) they’ve chosen to believe.
Gore, Jenkins insinuates, is a master at exploiting the “availability cascade” of the climate consensus, and that is why he got his Peace Prize: for being a brilliant opportunist. It is true that Gore won his award for popularizing climate science, not doing it. But Jenkins makes Gore’s work seem like manipulation and political spin, and there are many holes in his argument.
First of all, the scientific consensus that Jenkins pegs as mere artifice is actually quite robust. It has been almost twenty years since NASA scientist Jim Hansen first announced to Congress that global warming is a real, man-made threat, but it has taken all the time since then to achieve the consensus we have now. This is no mere child’s game in which one scientist parrots another in an attempt to validate some preconceived notion of how the climate works. For the last two decades, scientists have labored arduously in lab and field to amass a body of research that will settle important disputes about global warming. It has been an incremental and deliberative process that is only now producing any form of widespread agreement.
But Jenkins doesn’t fault the scientists alone: “Less surprising is the readiness of many prominent journalists to embrace the role of enforcer of an orthodoxy simply because it is the orthodoxy.” Whoa now. Journalists, like scientists, didn’t just start chirping about a consensus one day; they covered its gradual development piece-by-piece. Jenkins might remember that, until very recently, reporters were criticized for injecting too much skepticism (under the guise of “balance”) into their global warming articles. Taking into account the complete history of the climate debate, then, Jenkins’ insistence that the current consensus is artificial is both shallow and ill informed. Unfortunately, that is not the only problem with his column.
Elsewhere in Jenkins’ piece he writes that, “a Nobel has never been awarded for the science of global warming.” Um, except for when the one he’s writing about was presented jointly to Gore and the Intergovernmental Panel on Climate Change. Though the IPCC did not conduct any original research of its own, it vetted years’ of work-work that had already been peer-reviewed-by its member scientists and others.
