FLYING HIGH A18 With its sleek, radical four-seat plane, Cirrus Design is taking on Cessna and shaking up the small-plane market...
...that she could take far and fast. But as a long-lapsed pilot, the Los Angeles property developer did not want an aircraft that would intimidate her. Her flight instructor suggested an airplane that McCollum hadn't even heard of. One demonstration flight later, she was hooked on a Cirrus SR22, a sleek and powerful four-seater whose designers are trying to reinvent the small plane, not to mention the small-plane industry. "I'm a techno-nerd," says McCollum, "and when I saw those two computer screens in the cockpit where there usually are a bunch of round gauges...
...champions alike, is that they don't adequately account for clouds. In a warmer world, more water will evaporate from the oceans and presumably form more clouds. If they are billowy cumulus clouds, they will tend to shade the planet and slow down warming; if they are high, feathery cirrus clouds, they will trap even more heat...
Research by M.I.T. atmospheric scientist Richard Lindzen suggests that warming will tend to make cirrus clouds go away. Another critic, John Christy of the University of Alabama in Huntsville, says that while the models reproduce the current climate in a general way, they fail to get right the amount of warming at different levels in the atmosphere. Neither Lindzen nor Christy (both IPCC authors) doubts, however, that humans are influencing the climate. But they question how much--and how high temperatures will go. Both scientists are distressed that only the most extreme scenarios, based on huge population growth...
