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

Green Car Congress

However, aerosols have a much shorter lifespan in the atmosphere than the gases responsible for global warming, resulting in an atmospheric distribution that varies by region, especially in comparison to carbon dioxide. For example, aerosols from India cool their country of origin 20 times more than they cool the planet.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds. NASA Earth Observatory.

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Ozone pollution also damages crops and other plants. Scenario A2 and RCP 8.5. Ozone formation.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

They calculated emissions for ten cities (or metropolitan regions), which vary in population from 432,000 to 9,519,000; comparisons are in per capita terms. The releases include carbon dioxide; air pollutants, sewage and other water pollutants; and even excess heat that collects in vast expanses of concrete pavement and stone buildings.
