Bauer, S.E., K. Tsigaridis, and R.L. Miller, 2016: Significant atmospheric aerosol pollution caused by world food cultivation.

Not exact matches

In particular, they propose that cloud changes associated with aerosol particles in the atmosphere could be causing the weekend effect, though other pollution processes can not be ruled out at this time.

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.

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.

«A rapid cutback in greenhouse gas emissions could speed up global warming... because current global warming is offset by global dimming — the 2 - 3ºC of cooling cause by industrial pollution, known to scientists as aerosol particles, in the atmosphere.»

One suggestion that had been made some years ago — that the cooling may be caused by shading the sun by aerosol pollution — did not show up in the discussion on Saturday.

One theory is the decline in temperature from 1940 to 1970 was due to increased aerosols from pollution that caused a negative feedback.

The reason greenhouse gases can be (and probably are) responsible for more than 100 % of the observed warming is that other factors (mainly human aerosol pollution) have caused cooling at the same time.

You have one basic misunderstandiing about global dimming, it is not caused by CO2 but by SO2 and particulate pollution, what are called aerosols.

We always thought that — apart of course from soot [15 % of climate warming]-- such aerosol pollution creates cooling — as in the case of Chinese sulfur pollution and the Asian (Indian) brown cloud — and that air quality measures over recent decades in North America and Europe are now actually a major cause of increased warming speeds there — as the actual temperature catches up on the «CO2 baseline».

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).

As it turns out, forcings that have tended to cause cooling, like increased aerosol pollution, are particularly efficient.

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.

Atmospheric aerosol pollution, mixed with natural aerosols in the context of human caused global warming presents some interesting and extremely important challenges for consideration.

This is true, and has been attributed to higher levels of pollution aerosol particles, which commonly cause 20 % decreases in UV - B radiation in the summer (Wenny et.

Aerosols, that include dust, soot and sulphate particles, consist of solid or liquid particles suspended in air, are classic causes of air pollution.

We also emit conventional pollution, causing black soot and aerosols that have differing (and debated) effects on climate.

Cooling from 1940 - 1975 is widely understood to have been caused by aerosols (ie pollution) from unregulated industry and transportation.
