...Plan C." But many experts are skeptical of its practicality. "I have a hard time picturing doing this on the magnitude required, but it's an interesting idea," says University of Florida Professor of Geological Sciences Ellen Martin. "It may be easier to just dump a bunch of ice cubes out of an airplane, but it will take a lot of those too." (See pictures of the destruction of Hurricane Gustav...
...historical footnote. But America's overweight had their cause too. When hippies started staging "be-ins" to protest the Vietnam War, the first fat activists co-opted the idea: they staged their own event in New York City's Central Park, dubbed it a "Fat-In" and ate ice cream while burning posters of über-thin model Twiggy. Viva la revoluci...
...stylishly renovated 16th century ex-convent, with outdoor pool, in the hilltop Vomero quarter. Toast the start of your weekend at Pescheria Mattiucci, www.pescheriamattiucci.com, a tiny fish restaurant. The aperitivo hour, which rolls on until 10 p.m., sees hip Neapolitans wash down line-caught, sushi-style snacks with ice-cold white wine. Then step back in time at the majolica-tiled Osteria della Matonella, tel: (39-081) 416 541, where pasta alla Genoves (with veal and onions) and rum baba testify to 35 years of mama-licious Neapolitan cooking.

...carbon aren't in a one-to-one relationship. If they were, climate modeling would be a cinch. How much the globe will warm if we put a certain amount of CO2 into the air depends on the sensitivity of the climate. How vulnerable is the polar sea ice; how rapidly might the Amazon dry up; how fast could the Greenland ice cap disintegrate? That's why models like those from the Intergovernmental Panel on Climate Change spit out a range of predictions for future warming, rather than a single neat number...
Cloud cover is only one element of climate sensitivity. Scientists are also concerned about the earth's ice, which reflects sunlight back into space, making it a cooling factor, while seawater absorbs the sun's heat. That means that as polar sea ice melts because of warming, leaving more open water, the warming process could accelerate - which would then melt more ice. There are also concerns that as the permafrost in the Arctic thaws, it could release massive amounts of methane, a powerful greenhouse gas that would further accelerate warming...
