… Everybody knew. In 1958, on prime-time television, “The Bell Science Hour” — one of the most popular educational film series in American history — aired “The Unchained Goddess,” a film about meteorological wonders, produced by Frank Capra, a dozen years removed from “It’s a Wonderful Life,” warning that “man may be unwittingly changing the world’s climate” through the release of carbon dioxide. “A few degrees’ rise in the Earth’s temperature would melt the polar ice caps,” says the film’s kindly host, the bespectacled Dr. Research. “An inland sea would fill a good portion of the Mississippi Valley. Tourists in glass-bottomed boats would be viewing the drowned towers of Miami through 150 feet of tropical water.” Capra’s film was shown in science classes for decades.
Everyone knew — and we all still know. We know that the transformations of our planet, which will come gradually and suddenly, will reconfigure the political world order. We know that if we don’t act to reduce emissions, we risk the collapse of civilization. We also know that, without a gargantuan intervention, whatever happens will be worse for our children, worse yet for their children and even worse still for their children’s children, whose lives, our actions have demonstrated, mean nothing to us. …
We worry about the future. But how much, exactly? The answer, as any economist could tell you, is very little. Economics, the science of assigning value to human behavior, prices the future at a discount; the farther out you project, the cheaper the consequences. This makes the climate problem the perfect economic disaster. CONT.
