UC Riverside-led team identifies black carbon and tropospheric ozone as most likely drivers of large-scale atmospheric circulation change in the Northern hemisphere tropics Black carbon aerosols and tropospheric ozone, both manmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere, new research by a team of scientists shows. While stratospheric ozone depletion has...

Rice University study finds federal efforts most effective at cutting pollutants In a recent study published by the Journal of the Air & Waste Management Association, the Rice research group of environmental engineer Daniel Cohan looked at state implementation plans (SIPs) mandated by the United States Clean Air Act. SIPs detailed how states would attain standards set by the Environmental Protection Agency (EPA) for cutting ozone and other ground-level contaminants by 2009. The...

Worldwide increases in the incidences of asthma, allergies, infectious and cardiovascular diseases will result from a variety of impacts of global climate change, including rising temperatures, worsening ozone levels in urban areas, the spread of desertification, and expansions of the ranges of communicable diseases as the planet heats up, the professional organization representing respiratory and airway physicians stated in a new position paper released today. The paper is published...

Furthering Europe´s capacity to monitor atmospheric pollution, ESA has awarded a contract worth 45.5 million to Astrium UK to act as prime contractor for the Sentinel-5 Precursor satellite system. Scheduled to be launched in 2015, Sentinel-5 Precursor (Sentinel-5P) will be the first satellite dedicated to monitoring atmospheric chemistry for the Global Monitoring for Environment and Security (GMES) program. Astrium UK is now responsible for the delivery and integration of the...

Researchers the world over are seeking reliable ways to predict earthquakes, focusing on identifying seismic precursors that, if detected early enough, could serve as early warnings. New research, published this week in the journal Applied Physics Letters, suggests that ozone gas emitted from fracturing rocks could serve as an indicator of impending earthquakes. Ozone is a natural gas, a byproduct of electrical discharges into the air from several sources, such as from lightning, or,...

New Data Shows Antarctic Ozone Hole Still Remains

[ Watch the Video ] The Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, reached its annual peak on Sept. 12. It stretched to 10.05 million square miles, the ninth largest ozone hole on record. Above the South Pole, the ozone hole reached its deepest point of the season on Oct. 9, tying this year for the 10th lowest in this 26-year record. NASA and the National Oceanic and Atmospheric Administration (NOAA) use balloon-borne instruments, ground-based instruments...
