Guy sent me the abstract of an article from the most recent New Yorker magazine. I'm quoting part of it below. To see the whole abstract click here.
A few months ago, James Hansen, the director of NASA’s Goddard Institute for Space Studies (GISS), in Manhattan, joined a protest outside the Capitol Power Plant, in Washington, D.C. Thirty years ago, Hansen, who is sixty-eight, created one of the world’s first climate models, nicknamed Model Zero, which he used to predict most of what has happened in the climate since. Hansen has now concluded, partly on the basis of his latest modeling efforts and partly on the basis of observations made by other scientists, that the threat of global warming is far greater than even he had suspected. Unless immediate action is taken—including the shutdown of all the world’s coal plants within the next two decades—the planet will be committed to climate change on a scale society won’t be able to cope with.
