While worrying about Montana’s receding glaciers, Schweitzer, who is 50, should also worry about the fact that when he was 20 he was told to be worried, very worried, about global cooling. Science magazine (Dec. 10, 1976) warned of “extensive Northern Hemisphere glaciation.” Science Digest (February 1973) reported that “the world’s climatologists are agreed” that we must “prepare for the next ice age.” The Christian Science Monitor (”Warning: Earth’s Climate is Changing Faster Than Even Experts Expect,” Aug. 27, 1974) reported that glaciers “have begun to advance,” “growing seasons in England and Scandinavia are getting shorter” and “the North Atlantic is cooling down about as fast as an ocean can cool.” Newsweek agreed (”The Cooling World,” April 28, 1975) that meteorologists “are almost unanimous” that catastrophic famines might result from the global cooling that the New York Times (Sept. 14, 1975) said “may mark the return to another ice age.” The Times (May 21, 1975) also said “a major cooling of the climate is widely considered inevitable” now that it is “well established” that the Northern Hemisphere’s climate “has been getting cooler since about 1950.”

In the 1970s, “a major cooling of the planet” was “widely considered inevitable” because it was “well established” that the Northern Hemisphere’s climate “has been getting cooler since about 1950″ (New York Times, May 21, 1975). Although some disputed that the “cooling trend” could result in “a return to another ice age” (the Times, Sept. 14, 1975), others anticipated “a full-blown 10,000-year ice age” involving “extensive Northern Hemisphere glaciation” (Science News, March 1, 1975, and Science magazine, Dec. 10, 1976, respectively). The “continued rapid cooling of the Earth” (Global Ecology, 1971) meant that “a new ice age must now stand alongside nuclear war as a likely source of wholesale death and misery” (International Wildlife, July 1975). “The world’s climatologists are agreed” that we must “prepare for the next ice age” (Science Digest, February 1973). Because of “ominous signs” that “the Earth’s climate seems to be cooling down,” meteorologists were “almost unanimous” that “the trend will reduce agricultural productivity for the rest of the century,” perhaps triggering catastrophic famines (Newsweek cover story, “The Cooling World,” April 28, 1975). Armadillos were fleeing south from Nebraska, heat-seeking snails were retreating from Central European forests, the North Atlantic was “cooling down about as fast as an ocean can cool,” glaciers had “begun to advance” and “growing seasons in England and Scandinavia are getting shorter” (Christian Science Monitor, Aug. 27, 1974).

The pace of global warming is likely to be much faster than recent predictions, because industrial greenhouse gas emissions have increased more quickly than expected and higher temperatures are triggering self-reinforcing feedback mechanisms in global ecosystems, scientists said Saturday.

"We are basically looking now at a future climate that's beyond anything we've considered seriously in climate model simulations," Christopher Field, founding director of the Carnegie Institution's Department of Global Ecology at Stanford University, said at the annual meeting of the American Association for the Advancement of Science.

Field, a member of the United Nations' Intergovernmental Panel on Climate Change, said emissions from burning fossil fuels since 2000 have largely outpaced the estimates used in the U.N. panel's 2007 reports. The higher emissions are largely the result of the increased burning of coal in developing countries, he said.

Unexpectedly large amounts of carbon dioxide are being released into the atmosphere as the result of "feedback loops" that are speeding up natural processes. Prominent among these, evidence indicates, is a cycle in which higher temperatures are beginning to melt the arctic permafrost, which could release hundreds of billions of tons of carbon dioxide and methane into the atmosphere, said several scientists on a panel at the meeting.

Mum's the word for George Will and the Washington Post when it comes to explaining how misinformation on global warming got into Will's most recent column.

Yesterday morning we called Will to ask him about the misrepresentations in his Sunday column. We also called Fred Hiatt, the editor of the paper's editorial page, to ask about the editing process that the Post's editorial page employs. Neither chose to answer our questions [...]

Will's assistant told us that Will might get back to us later in the day to talk about the column. And Hiatt said he was too busy to talk about it just then, but that he'd try to respond to emailed questions. So we emailed him yesterday's post, with several questions about the editing process, then followed up with another email late yesterday afternoon.

But still nothing from either of them, over twenty-four hours after the first contact was made. Nor has the online version of Will's column been updated, even to reflect the fact that the ACRC has utterly disavowed the claim Will attributes to it.

CHOMSKY: [A] few years ago George Will wrote a column in Newsweek called "Mideast Truth and Falsehood," about how peace activists are lying about the Middle East, everything they say is a lie. And in the article, there was one statement that had a vague relation to fact: he said that Sadat had refused to deal with Israel until 1977. So I wrote them a letter, the kind of letter you write to Newsweek—you know, four lines—in which I said, "Will has one statement of fact, it's false; Sadat made a peace offer in 1971, and Israel and the United States turned it down." Well, a couple days later I got a call from a research editor who checks facts for the Newsweek "Letters" column. She said: "We're kind of interested in your letter, where did you get those facts?" So I told her, "Well, they're published in Newsweek, on February 8, 1971"—which is true, because it was a big proposal, it just happened to go down the memory hole in the United States because it was the wrong story. So she looked it up and called me back, and said, "Yeah, you're right, we found it there; okay, we'll run your letter." An hour later she called again and said, "Gee, I'm sorry, but we can't run the letter." I said, "What's the problem?" She said, "Well, the editor mentioned it to Will and he's having a tantrum; they decided they can't run it." Well, okay.
