...from the Arabian peninsula to the western Pacific Ocean - has long captured the curiosity of scientists. A report released in the Jan. 23 issue of Science breathes fresh air into that ongoing study, confirming that the mass, nicknamed the 'Brown Cloud' but comprised of several small, local clouds, is soot from human burning of wood, dung and crop residue, as well as industrial processes and traffic pollution...
...summer." It followed the Tambora Volcano eruption in Indonesia in 1815. It was sudden climate change on a similar scale, and it resulted in a severe famine in Europe, food riots and mass emigrations. Volcanic aerosols have a lifetime of about a year in the stratosphere. The lifetime of soot from nuclear fires is about five years. It's obviously much harder for a society to recover from such an extended cooling...

She sucked in great lungfuls of it as she ran as fast and far away as she could from that house of sin. She stopped finally on a hilltop overlooking the manor, unable to run anymore.

...putting another 660,000 cars on the road. In detail, Thursday's decision means that any new air pollution permits for coal plants will require that Best Available Control Technology (BACT) be used to reduce CO2 emissions, the same criteria currently used for other pollutants, like sulfur dioxide or soot. BACT requires companies involved in power plants to use the best available technology to control pollutants - it's a tool to keep pollution controls up to date as both safety technology and our understanding of pollution impoves. In the past, CO2 wasn't affected by BACT because the EPA didn...
