Greenhouse Academy Quotes

for the next century could raise the world’s temperature some 4°C (7.2°F), bringing serious coastal flooding and other damage.” The Conservation Foundation urged renewed funding for Keeling’s CO 2 project and pressed the National Academy of Sciences to pay attention to the subject. From then on, awareness of climate change ascended right along with the Keeling Curve. In 1971 Barry Commoner’s environmentalist bestseller, The Closing Circle, gave an early public warning about greenhouse gases. In 1978 a young congressman from Tennessee, Albert Gore, held hearings on global warming, starring his Harvard teacher Roger Revelle, who had sponsored the Keeling CO 2 research

ethanol may actually make some kinds of air pollution worse. It evaporates faster than pure gasoline, contributing to ozone problems in hot temperatures. A 2006 study published in the Proceedings of the National Academy of Sciences concluded that ethanol does reduce greenhouse gas emissions by 12 percent relative to gasoline, but it calculated that devoting the entire U.S. corn crop to make ethanol would replace only a small fraction of American gasoline consumption. Corn farming also contributes to environmental degradation due to runoff from fertilizer and pesticides. But to dwell on the science is to miss the point. As the New York Times noted in the throes of the 2000 presidential race, ―Regardless of whether ethanol is a great fuel for cars, it certainly works wonders in Iowa campaigns. The ethanol tax subsidy increases the demand for corn, which puts money in farmers‘ pockets. Just before the Iowa caucuses, corn farmer Marvin Flier told the Times, ―Sometimes I think [the candidates] just come out and pander to us, he said. Then he added, ―Of course, that may not be the worst thing. The National Corn Growers Association figures that the ethanol program increases the demand for corn, which adds 30 cents to the price of every bushel sold. Bill Bradley opposed the ethanol subsidy during his three terms as a senator from New Jersey (not a big corn-growing state). Indeed, some of his most important accomplishments as a senator involved purging the tax code of subsidies and loopholes that collectively do more harm than good. But when Bill Bradley arrived in Iowa as a Democratic presidential candidate back in 1992, he ―spoke to some farmers‖ and suddenly found it in his heart to support tax breaks for ethanol. In short, he realized that ethanol is crucial to Iowa voters, and Iowa is crucial to the presidential race.

One response to the prospect of climate change is to deny that it is occurring or that human activity is the cause. It's completely appropriate of course to challenge the hypothesis of anthropogenic climate change on scientific grounds, particularly given the extreme measures it calls for if it is true. The great virtue of science is that a true hypothesis will in the long run withstand attempts to falsify it. Anthropogenic climate change is the most vigorously challenged scientific hypothesis in history. By now, all the major challenges such as that global temperatures have stopped rising, that they only seem to be rising because they were only measured in urban heat islands, or that they really are rising, but only because the sun is getting hotter, have been refuted, and even many skeptics have been convinced. A recent survey found that exactly 4 out of 69,406 authors of peer reviewed articles in the scientific literature rejected the hypothesis of anthropogenic global warming. And that the peer reviewed literature contains no convincing evidence against the hypothesis. Nonetheless, a movement within the American political right, heavily underwritten by fossil fuel interests, has prosecuted a fanatical and mendacious campaign to deny that greenhouse gases are harming the planet. In doing so, they have advanced the conspiracy theory that the scientific community is fatally infected with political correctness and ideologically committed to a government takeover of the economy. As someone who considers himself something of a watchdog for politically correct dogma in academia, I can state that this is nonsense. Physical scientists have no such agenda and the evidence speaks for itself. And it's precisely because of challenges like this that scholars in all fields have a duty to secure the credibility of the academy by not enforcing political orthodoxies.

The press would indeed take the “conservative” position. A New York Times reporter put it this way: “The Academy found that since there is no politically or economically realistic way of heading off the greenhouse effect, strategies must be prepared to adapt to a ‘high temperature world.’”50 But the Academy hadn’t found that; the committee had asserted it. And it wasn’t the Academy; it was Bill Nierenberg and a handful of economists.
