Sentences with phrase «effect of aerosol pollution»

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

These underestimate the global cooling effects of aerosol pollution, so also underestimate sensitivity.

Not exact matches

«We've shown that under clean and humid conditions, like those that exist over the ocean and some land in the tropics, tiny aerosols have a big impact on weather and climate and can intensify storms a great deal,» said Fan, an expert on the effects of pollution on storms and weather.

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.

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

Further, since these industrial pollution centers have had widespread aerosol thermal changes, the localized effects would have shown «hotbeds» of cooling (sorry).

From sheer thermal inertia of the oceans, but also because if you close down all coal power stations etc., aerosol pollution in the atmosphere, which has a sizeable cooling effect, will go way down, while CO2 stays high.

Not it is not similar because one event injected sulfate aerosols into the stratosphere where they stayed for years and affected the globe while the other («human particulates and aerosol pollution») were produced in the troposphere and have a residency time in the atmosphere of about 4 days and had only a regional effect.

Urban heat island - The relative warmth of a city compared with surrounding rural areas, associated with changes in runoff, the concrete jungle effects on heat retention, changes in surface albedo, changes in pollution and aerosols, and so on.

So when you mix the two kinds of aerosol pollution up in the Asian brown cloud, one would expect climate effects to even out.

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

However — a group of scientists of the US Department of Energy Pacific Northwest National Laboratory, the University of Maryland and the Hebrew University of Jerusalem now say that aerosol pollution does not necessarily lead to (low - lying) stratus clouds one would appreciate for climatic cooling, but that it can also be a factor in the creation of thunderstorm clouds, clouds that have a complicated climate effect, but that are suspected of being net warmers.

He also found that much of the effect was due to natural aerosols which would not be affected by human activities, so the cooling effect of changes in industrial pollution would be much less than he had calculated.

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).

If we account for the cooling effect of sulphur aerosols from industrial pollution, greenhouse gases have already contributed 2 ℃ of global warming.

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

There, he co-authored an article for Science arguing that the warming effect caused by rising amounts of carbon - dioxide in the atmosphere would be swamped by the cooling effect caused by aerosol pollution like dust and smoke.

As aerosol pollution is predicted to decrease over the next few decades, unmasking of the greenhouse effect may lead to accelerated global warming.storms and ocean plankton The human - generated aerosols are derived from industry, motor vehicles and vegetation burning.

In the United States, new research from the City College of New York on the effects of particle pollution on weather patterns around Manhattan has shown that aerosols can either increase or decrease local rainfall, sometimes creating situations where one area will be deluged while a neighboring town will remain dry.

About 90 % or more of the rest of the committed warming of 1.6 °C will unfold during the 21st century, determined by the rate of the unmasking of the aerosol cooling effect by air pollution abatement laws and by the rate of release of the GHGs - forcing stored in the oceans.

S. Ichtiaque Rasool and Stephen Schneider of NASA, for example, modelled the effects of pollution in the form of aerosols and sulphur emissions in the atmosphere and discovered that a significant increase of such pollution could - possibly - lead to a cooling episode.

Warming from decade to decade can also be affected by human factors such as variations in the emissions, from coal - fired power plants and other pollution sources, of greenhouse gases and of aerosols (airborne particles that can have both warming and cooling effects).
