NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

In particular, the study led by Drew Shindell found that methane emissions have a larger warming impact due to those interactions than accounted for in current carbon-trading schemes or in the Kyoto Protocol. And hydroxyls drive long chains of reactions involving other common gases, including ozone. —Drew Shindell.

US and UK researchers report direct measurement of key atmospheric reactant; more rapid formation of secondary aerosols

Green Car Congress

The researchers believe the measurements will substantially impact the understanding of atmospheric chemistry mechanisms—in particular, in the more rapid formation of secondary aerosols, important in the formation of local smog as well as in global climate change. Carl Percival. —Welz et al. —Marston (2012). Welz et al.

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Life cycle inventories have typically been presented at global, national, or regional levels—sufficient for understanding global processes such as climate change and fossil fuel depletion, but insufficient for the analysis of local processes such as air pollution, according to the researchers. 1 , corn ethanol: 10).

Researchers Determine Process Through Which Hydrocarbon Compounds Emitted by Trees Form Aerosols, With Impact on Human Health and Climate

Green Car Congress

Aerosols impact human health, due to their ability to penetrate deep into lungs, and impact Earth’s climate through the scattering and absorption of solar radiation and through serving as the nuclei on which clouds form, noted co-author Prof. Tags: Climate models Emissions Health. John Seinfeld from Caltech. “ Science , 325, 730-733.

Berkeley study identifies diesel as main source of vehicular secondary organic aerosols

Green Car Congress

Organic aerosol (OA) in the atmosphere is detrimental to human health and represents a highly uncertain forcing of climate change. The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone.
