Obama to Introduce Sweeping New Controls on Ozone Emissions
2014-11-26 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: The Obama administration is expected to release on Wednesday a contentious and long-delayed environmental regulation to curb emissions of ozone, a smog-causing pollutant linked to asthma, heart disease and premature death. The sweeping regulation, which would aim at smog from power plants and factories across the country, particularly in the Midwest, would be the latest in a series of Environmental Protection Agency controls on air pollution that wafts from smokestacks and tailpipes. Such regulations,...

U.S. EPA expected to tighten long-awaited ozone standards: sources
2014-11-26 03:28:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The Environmental Protection Agency is expected to propose on Wednesday more stringent air quality standards for ground-level ozone, the main culprit in smog, sources said. Under a court-ordered deadline of next Monday to release its proposal, the agency could propose a National Ambient Air Quality Standard between 65 and 70 parts per billion concentration of ozone, and take comment on standards within a 60-75 ppb range, sources familiar with the matter said. That would compare with the current...

Greenhouse gases: More emphasis needed on ozone, methane impact, scientists say
2014-11-21 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Australian Broadcasting Corporation: There is too much emphasis on carbon dioxide as a greenhouse gas and other forms such as ozone, methane and sulphur dioxide should receive more attention, a group of scientists say. Writing a comment piece in the science journal Nature, the group argued that other forms of air pollutants contributed to one in eight deaths worldwide, and nearly 50 million deaths could be avoided by 2040 if emissions were cut in half. Other types of pollutants, such as methane, had a higher global warming potential...

Health groups demand strict ozone standards
2014-11-19 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Hill: Healthcare professionals want the EPA to adopt the strictest standards possible for ozone pollution. A new standard is not only long overdue, but publicly needed, Janice Nolen, assistant vice president of national policy at the American Lung Association, said in a telephone conference on Tuesday. The current standard of 75 parts per billion [ppb] fails to adequately protect public health. Were proposing a new rule of 60 parts per billion over a period of 8 hours. By court order, the...
