Clark compared global warming to backpacking, saying reductions in carbon dioxide emissions will come in "little squeezes...
Whatever glamour there is these days in organic chemistry -- the study of the complex, carbon-based molecules that are the basis of life -- adheres mostly to the genetic engineers, those futuristic scientists who turn living cells into tiny factories for drugs and other substances. But the fact is that most pharmaceutically useful compounds are made the old-fashioned way, by combining reagents in a laboratory flask. Last week the Royal Swedish Academy returned to the roots of the science. Elias James Corey, 62, who won the Nobel Prize for Chemistry, is an organic chemist's chemist, a master...
...greenhouse effect with a "White House effect." He promised to convene personally an international conference on global warming at the White House. He reneged on these pledges; when Europeans actually held a conference in the Netherlands, Bush specifically instructed the U.S. delegate not to agree to any restrictions on carbon dioxide emissions...
...features as small as 120 meters (394 ft.) across, 10 times smaller than anything ever seen before. That should be enough to begin answering some important questions about the geology and atmosphere of the planet. Although nearly the same size as Earth, Venus has an atmosphere thick with carbon dioxide and sulfuric acid. These gases have created an atmospheric pressure at the surface 90 times that of Earth and led to a greenhouse effect that keeps the temperature at 470 degrees C (900 degrees F), hot enough to melt lead and ensure that liquid water cannot exist...
...demand could escalate rapidly in the next decade, especially in areas of heavy pollution. "Natural gas has the lowest carbon dioxide emissions of any of the fossil fuels," notes James MacKenzie, a senior associate at the World Resources Institute, an environmental group. More natural gas could be used for electrical generation, mainly to replace coal. "Power plants can switch fuels and cut their emissions of sulfur instantly with relatively inexpensive changes in equipment," says MacKenzie. The most untapped market is transportation. More than 30,000 cars and trucks in the U.S. run on natural gas, and automakers have shown increasing...
