My 1975 'Cooling World' story doesn't make today's climate scientists wrong
It's time for deniers of human-caused global warming to stop using an old magazine story as ammunition against the consensus of today's climate scientists.
(Inside Science) – "The central fact is that, after three quarters of a century of extraordinarily mild conditions, the Earth seems to be cooling down. Meteorologists disagree about the cause and extent of the cooling trend, as well as over its specific impact on local weather conditions. But they are almost unanimous in the view that the trend will reduce agricultural productivity for the rest of the century." – Newsweek: April 28, 1975
That's an excerpt from a story I wrote about climate science that appeared almost 40 years ago. Titled "The Cooling World," it was remarkably popular; in fact it might be the only decades-old magazine story about science ever carried onto the set of a late-night TV talk show. Now, as the author of that story, after decades of scientific advances, let me say this: while the hypotheses described in that original story seemed right at the time, climate scientists now know that they were seriously incomplete. Our climate is warming -- not cooling, as the original story suggested.
Nevertheless, certain websites and individuals that dispute, disparage and deny the science that shows that humans are causing the Earth to warm continue to quote my article. Their message: how can we believe climatologists who tell us that the Earth's atmosphere is warming when their colleagues asserted that it's actually cooling?
Well, yes, we should trust them, despite the views of detractors such as comedian Dennis Miller, who brought my story to The Tonight Show in 2006. Several atmospheric scientists did indeed believe in global cooling, as I reported in the April 28, 1975 issue of Newsweek. But that was then.
In the 39 years since, biotechnology has flowered from a promising academic topic to a major global industry, the first test-tube baby has been born and become a mother herself, cosmologists have learned that the universe is expanding at an accelerating rate rather than slowing down, and particle physicists have detected the Higgs boson, an entity once regarded as only a theoretical concept. Seven presidents have served most of 11 terms. And Newsweek has become a shadow of its former self.
