Carnegie study finds climate impact of particulates varies greatly depending on where the pollution originated

Green Car Congress

However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. An open-access paper on their work is published in Nature Communications.

Study associates long-term exposure to air pollution with increasing emphysema

Green Car Congress

Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. Ground-level ozone is mostly produced when ultraviolet light reacts with pollutants from fossil fuels.

California “gasoline superuser” bill advances; focusing ZEV incentives on reducing gasoline use

Green Car Congress

By shifting the biggest gasoline users into ZEVs first, AB 2816 also reduces the total number of ZEVs that would be needed to reach the state’s near-term target of cutting light-duty vehicle emissions in half by 2030. Light duty vehicles cause 28% of California’s total carbon emissions and pollute the air near freeways and busy roads.

Pollution in Eastern China Cuts Light, Useful Rainfall

Green Car Congress

New research shows that air pollution in eastern China has reduced the amount of light rainfall over the past 50 years and decreased by 23% the number of days of light rain in the eastern half of the country. But light rainfall that sustains crops has decreased everywhere. The south lost more days—8.1 days per decade.
