...Under the new rule, which became final with Johnson's signature, the national standard for daily exposure to fine particle pollution will drop from 65 micrograms per cubic meter to 35 micrograms per cubic meter. That's a significant change; under the tighter rules, an additional 32 counties in the U.S. will now have substandard air quality. At the same time, however, the agency decided to leave the annual standards for exposure to fine particles at their current level - 15 micrograms per cubic meter...
...consideration since the late 1990s. We balanced performance and cost, and it turned out to be what customers wanted. If you look at what makes Opteron such a good product, it has tremendous benefits in cost of energy consumption and in terms of architecture. The performance per watt per cubic meter has become a very critical parameter--and we excel in such measures...
...can’t fix.” Calling for a “bipartisan, multinational, multi-generational” coalition to address climate change, Browner began her speech by rattling off nearly a dozen numbers to highlight the scope of the problem. Among them were the 36 cubic miles of Arctic ice—an amount equal to 225 times the annual water use of Los Angeles—that melted in the past year, and the 27 tropical storms, including four Category 5 hurricanes, that developed in the Atlantic...
...University of Kansas, analyzed data from Canadian and European satellites and found that Greenland ice is not just melting but doing so more than twice as fast, with 53 cu. mi. draining away into the sea last year alone, compared with 22 cu. mi. in 1996. A cubic mile of water is about five times the amount Los Angeles uses in a year...
...Ireland’s 2004 ban on smoking in public places. According to the study, pubs in cities without smoking bans had significantly higher levels of fine-particle pollution. The Environmental Protection Agency sets standards for outdoor, but not indoor, air quality; any levels above 301 micrograms per cubic meter are “hazardous.” The average level in smoking pubs was much higher at 340 micrograms per cubic meter. The results “underscore the importance of smoke-free policies,” according to the study’s authors. HSPH Professor...
