Sentences with phrase «reduce aerosol pollution»

Probably because of both mid-century «global dimming» from aerosols, and subsequent «global brightening» from reduced aerosol pollution, a different interval — e.g., 1976 to the present — would have required a very different dividing up of attributions.

«This study has demonstrated for the first time, using in - situ PM measurements, that reducing aerosol pollution is driving the Insolation Brightening phenomenon and that the trends in aerosol pollution, particularly for sulphate aerosol, is directly linked to anthropogenic emissions.

Not exact matches

During this event, the aerosols stayed close to the surface due to the presence of a anticyclone hovering over the study region at sea - level, «reducing the amount of shortwave irradiance reaching the surface and causing greater radiative cooling,» states Obregón, who likens the effects of desert dust with those resulting from certain forest fires or episodes of high pollution.

Li said the study's findings should further spur countries like China and India to cut aerosol emissions so they reduce pollution and thereby increase their solar electricity generation more rapidly, in addition to the already known health benefits.

Published in the Proceedings of the National Academy of Sciences, the study shows that in the most polluted areas of northern and eastern China, aerosol pollution is reducing the potential for solar electricity generation by as much as one and a half kilowatt - hour per square meter per day, or up to 35 percent.

Indeed, conventional wisdom held that higher levels of aerosol pollution in the atmosphere should cool the earth's climate because aerosols can increase cloudiness; they not only reduce precipitation, which raises the water content in clouds, but they also increase the size of the individual water droplets, which in turn causes more warming sunlight to be reflected back into space.

Ironically, future reductions of particulate air pollution may exacerbate global warming by reducing the cooling effect of reflective aerosols.

It is likely that at least some of this change, particularly over Europe, is due to decreases in pollution; most governments have done more to reduce aerosols released into the atmosphere that help global dimming instead of reducing CO2 emissions.

In the future, net radiation may be reduced through aerosol pollution, which will push the system qualitatively closer to the critical threshold (7).

Ironically, future reductions of particulate air pollution may exacerbate global warming by reducing the cooling effect of reflective aerosols.

Much warming may have been aerosol pollution reducing cloud albedo.

This is as to be expected, since continued efforts to reduce atmospheric aerosols in the West have resulted in less dimming (more warming), while in the East increasing pollution has caused more dimming (less warming).

«Between the Fourth and Fifth [IPCC] Assessment Reports the best estimate of the cooling effect of aerosol pollution was greatly reduced.

However, this offsetting effect is unlikely to remain in the future as improved pollution controls are expected to significantly reduce the cooling effect of aerosols over the course of coming decades: Meinshausen et al (2006).

Thankfully, the U.S. and many other countries around the world have worked to reduce haze - forming aerosol pollution, and we can all breathe a little easier.

But I've been shifting my thinking based on recent conversations with some of the authors below about the feasibility of incremental management of sun - blocking aerosols, even as warming aerosols contributing to conventional air pollution are reduced.

Tall smokestacks effectively reduce ground - level air pollution, but they do not reduce the cooling effect of aerosol / particulate pollution.
