Sentences with phrase «because of aerosol pollution»

Among the issues discussed: solar energy variations that could contribute to the ebb and flow of ice ages, new understanding of ice ages and the possibility of cooling because of aerosol pollution, but also the possible confounding factor of increasing greenhouse gases:

Not exact matches

Because they are short - lived, aerosols generally aren't distributed evenly through the atmosphere like CO2, but tend to be concentrated near centres of 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.

Aerosols from the production of heavy oil is a growing climate and pollution concern because new tar sands developments are on the drawing board in Venezuela, Utah and elsewhere, the study says.

Aerosols in urban air pollution and from major industries such as the Canadian tar sands are of concern to scientists because they can affect regional climate patterns and have helped to warm the Arctic.

«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.»

So now get rid of most of the world's sulfate aerosols in the next 50 years because it's currently killing people, plants and destroying ecosystems (acid rain, pollution).

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.

Other influences: aerosols, likely cooling, though the temporal variation is key (eg, they are net cooling overall, but their trend in the past 20 years may actually be net warming because of sulfate pollution control in the industrialized nations).

The approximate stand - still of global temperature during 1940 - 1975 is generally attributed to an approximate balance of aerosol cooling and greenhouse gas warming during a period of rapid growth of fossil fuel use with little control on particulate air pollution, but quantitative interpretation has been impossible because of the absence of adequate aerosol measurements.

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.

The approximate stand - still of global temperature during 1940 - 1975 is generally attributed to an approximate balance of aerosol cooling and greenhouse gas warming during a period of rapid growth of fossil fuel use with little control on particulate air pollution, but satisfactory quantitative interpretation has been impossible because of the absence of adequate aerosol measurements.
