QUOTING
Many studies from the nineteenth century on suggested that industrial and other contributions to increasing carbon dioxide might lead to global warming. Problems with such predictions were also long noted, and the general failure of such predictions to explain the observed record caused the field of climatology as a whole to regard the suggested mechanisms as suspect. Indeed, the global cooling trend of the 1950s and 1960s led to a minor global cooling hysteria in the 1970s. All that was more or less normal scientific debate, although the cooling hysteria had certain striking analogues to the present warming hysteria including books such as The Genesis Strategy by Stephen Schneider and Climate Change and World Affairs by Crispin Tickell--both authors are prominent in support of the present concerns as well--"explaining'' the problem and promoting international regulation. There was also a book by the prominent science writer Lowell Ponte (The Cooling) that derided the skeptics and noted the importance of acting in the absence of firm, scientific foundation. There was even a report by the National Research Council of the U.S. National Academy of Sciences reaching its usual ambiguous conclusions. But the scientific community never took the issue to heart, governments ignored it, and with rising global temperatures in the late 1970s the issue more or less died. In the meantime, model calculations--especially at the Geophysical Fluid Dynamics Laboratory at Princeton--continued to predict substantial warming due to increasing carbon dioxide. Those predictions were considered interesting, but largely academic, exercises--even by the scientists involved.
The present hysteria formally began in the summer of 1988, although preparations had been put in place at least three years earlier. That was an especially warm summer in some regions, particularly in the United States. The abrupt increase in temperature in the late 1970s was too abrupt to be associated with the smooth increase in carbon dioxide. Nevertheless, James Hansen, director of the Goddard Institute for Space Studies, in testimony before Sen. Al Gore's Committee on Science, Technology and Space, said, in effect, that he was 99 percent certain that temperature had increased and that there was some greenhouse warming. He made no statement concerning the relation between the two.
Despite the fact that those remarks were virtually meaningless, they led the environmental advocacy movement to adopt the issue immediately. The growth of environmental advocacy since the 1970s has been phenomenal. In Europe the movement centered on the formation of Green parties; in the United States the movement centered on the development of large public interest advocacy groups. Those lobbying groups have budgets of several hundred million dollars and employ about 50,000 people; their support is highly valued by many political figures. As with any large groups, self-perpetuation becomes a crucial concern. "Global warming'' has become one of the major battle cries in their fundraising efforts. At the same time, the media unquestioningly accept the pronouncements of those groups as objective truth.
Within the large-scale climate modelling community--a small subset of the community interested in climate--however, the immediate response was to criticize Hansen for publicly promoting highly uncertain model results as relevant to public policy. Hansen's motivation was not totally obvious, but despite the criticism of Hansen, the modelling community quickly agreed that large warming was not impossible. That was still enough for both the politicians and advocates who have generally held that any hint of environmental danger is a sufficient basis for regulation unless the hint can be rigorously disproved. That is a particularly pernicious asymmetry, given that rigor is generally impossible in environmental sciences.
Other scientists quickly agreed that with increasing carbon dioxide some warming might be expected and that with large enough concentrations of carbon dioxide the warming might be significant. Nevertheless, there was widespread skepticism. By early 1989, however, the popular media in Europe and the United States were declaring that "all scientists'' agreed that warming was real and catastrophic in its potential.
As most scientists concerned with climate, I was eager to stay out of what seemed like a public circus. But in the summer of 1988 Lester Lave, a professor of economics at Carnegie Mellon University, wrote to me about being dismissed from a Senate hearing for suggesting that the issue of global warming was scientifically controversial. I assured him that the issue was not only controversial but also unlikely. In the winter of 1989 Reginald Newell, a professor of meteorology at the Massachusetts Institute of Technology, lost National Science Foundation funding for data analyses that were failing to show net warming over the past century. Reviewers suggested that his results were dangerous to humanity. In the spring of 1989 I was an invited participant at a global warming symposium at Tufts University. I was the only scientist among a panel of environmentalists. There were strident calls for immediate action and ample expressions of impatience with science. Claudine Schneider, then a congressman from Rhode Island, acknowledged that "scientists may disagree, but we can hear Mother Earth, and she is crying.'' It seemed clear to me that a very dangerous situation was arising, and the danger was not of "global warming'' itself.
In the spring of 1989 I prepared a critique of global warming, which I submitted to Science, a magazine of the American Association for the Advancement of Science. The paper was rejected without review as being of no interest to the readership. I then submitted the paper to the Bulletin of the American Meteorological Society, where it was accepted after review, rereviewed, and reaccepted--an unusual procedure to say the least. In the meantime, the paper was attacked in Science before it had even been published. The paper circulated for about six months as samizdat. It was delivered at a Humboldt conference at M.I.T. and reprinted in the Frankfurter Allgemeine.
