Sentences with phrase «cooling effect of pollution»

Not exact matches

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

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.

«This allows the new approach to implicitly include the cooling effects of particulate pollution that are still poorly quantified in computer models,» he adds.

It accounted for atmospheric pollution effects that have been cooling Earth by reflecting sunlight into space, and for the slow response time of the ocean.

The draft says their cooling effect is 40 per cent less than thought in 2007, suggesting this side effect of air pollution has been overstated.

The draft says their cooling effect is 40 per cent less than thought in 2007, suggesting this positive side effect of air pollution has been overstated.

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

(1) Of the other anthropogenic factors, some have a warming effect (other greenhouse gases such as methane) while others have a cooling effect (air pollution).

Particle Pollution's Cooling Effect... Plus Death Interestingly, this particle pollution has the opposite effect on the climate as does the ship's carbon emissions: The particles have a cooling effect that is at least five times greater than the warming effect of the CO2 emiCooling Effect...

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.

One prevailing theory for this difference is that the NH experienced the cooling effects of tropospheric pollution more so than the SH during the middle 20th century.

I have already made it clear elsewhere that the additional resistor effect of human CO2 would be insignificant in relation to that from the rest of the air and the oceans together with the varying solar and oceanic heating and cooling effects but we still need to know for sure whether it is significant at all over periods of less than several hundred years because that may be the time we need to solve our energy, pollution, resource and population problems.

The effects can cause either warming or cooling, depending of the chemical - optical properties of the pollution particles.

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.

Scientists of the time disagreed on whether the greatest global risk was cooling by atmospheric pollution or greenhouse effect warming.

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

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.

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).
