...most dangerous and intractable of all of the impacts of human activities on the environment is the disruption of the global climate by anthropogenic greenhouse gases, above all carbon dioxide from the combustion of fossil fuels. This is the most dangerous of environmental impacts because climate is the “envelope” within which all other environmental conditions and processes must operate. If the envelope is distorted too much, as we appear to be well on our way to doing, every part of the environment is at risk. And the disruption of climate by greenhouse gases...
...antique hound. But two chemists with the Los Alamos National Laboratory in New Mexico are tracking down a more unusual relic: old air. Allen Ogard and Jane Poths are seeking samples of air that was sealed off decades or even centuries ago. Reason: to determine whether the level of carbon dioxide in the atmosphere has increased in the two centuries since the start of the industrial revolution. By some calculations, the extensive burning of oil and other fossil fuels has added to the shield of carbon dioxide around the earth, resulting in a heightened greenhouse effect that traps heat...
...determine if a button or sextant is permeable, the investigators place the object in a container filled with neon, then later examine the item with a mass spectrometer to see if neon has entered it. If the object proves snug, its carbon dioxide is analyzed. Such an operation may require drilling a small hole through the antique object, but surprisingly, museum curators have not protested. Says Ogard: "Most have said it's fine as long as it's not in an obvious place...
DIED. Dan White, 39, former San Francisco supervisor who in 1978 shot to death the city's mayor, George Moscone, and its first openly homosexual supervisor, Harvey Milk; by his own hand (carbon-monoxide poisoning); in San Francisco. At his 1979 trial, White pleaded "diminished capacity," contending that a diet of sugary junk food had aggravated his severe psychological problems, an argument that became known as the "Twinkie defense." When White was convicted only of voluntary manslaughter, 5,000 rioters, most of them gays, stormed city hall. Following his release after five years in prison, White, unemployed and dogged...
...Soon the issue of uranium sales will come under debate in Australia again. Given its expansion and global carbon-emissions protocols, China's energy future is looking increasingly nuclear. Australia has the world's largest uranium reserves. The two countries are working on a nuclear safeguards agreement. "We believe in the peaceful use of nuclear energy," says Foreign Minister Downer. Although environmentalists are not the political force they have been in the past, uranium mine expansions or a Chinese stake in the industry would bring protesters to the streets. The Howard government has changed the way Australia addresses Chinese human...
