...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...
...areas by acquiring such choice firms as John Lobb, the prestigious British shoemaker, and Cristalleries de St. Louis, the 223-year- old French glassware manufacturer. Fancy a pair of calfskin-clad garden shears? (They will set you back $475.) A jungle-print bath towel? ($525.) A suitcase made of carbon fiber, adapted from the sheathing on the European Space Agency's Ariane rocket? ($5,450.) Dumas has expanded the product line to 30,000 items...
...these things alive? That depends on how the term is defined. Surprisingly, there is no clear definition of "life." Most of the criteria put forward in the past are anthropocentric. Life on earth is carbon-based and built around the nucleic acids RNA and DNA, but that may be a historical accident. Most living things metabolize and multiply, but not all. Viruses have no metabolisms of their own; mules cannot reproduce. Many living things grow, but so do clouds and garbage dumps...
