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...

Connie K. Ho for RedOrbit.com 13,000 premature deaths in the United Kingdom were caused by emissions from cars, planes, power plants, and trucks, according to a new study by MIT Researchers. The findings, published in this month´s issue of the journal Environmental Science and Technology, are based off of data from 2005. Steven Barrett and co-author Steve Yim found that car and truck exhaust was the leading cause of premature death. 3,300 affected people died each year, as compared...

New research from North Carolina State University shows that federal requirements governing diesel engines of new tractor trailer trucks have resulted in major cuts in emissions of particulate matter (PM) and nitrogen oxides (NOx) — pollutants that have significant human health and environmental impacts. “These requirements for new emission control technologies have increased costs for truck owners and operators, and we wanted to know whether there was any real benefit,”...

The first real-world, head-to-head comparison of "improved cookstoves" (ICs) and traditional mud stoves has found that some ICs may at times emit more of the worrisome "black carbon," or soot, particles that are linked to serious health and environmental concerns than traditional mud stoves or open-cook fires. The report, which raises concerns about the leading hope as a clean cooking technology in the developing world, appears in ACS' journal Environmental Science &Technology....

Where a child lives can greatly affect his or her risk for asthma. According to a new study by scientists at Columbia University, neighborhood differences in rates of childhood asthma may be explained by varying levels of air pollution from trucks and residential heating oil. Results appear online in the Journal of Exposure Science and Environmental Epidemiology. In New York City, where the study was conducted, asthma among school-age children ranges from a low of 3% to a high of 19%...
