Sentences with phrase «sulfate aerosols in the atmosphere»

In the mid-20th century, coal - burning power plants and other sources released huge amounts of sulfur dioxide, which then formed toxic sulfate aerosols in the atmosphere.

I'll let John Philips dig up the studies but just to add a little more explanation: It is not only that the sulfate aerosol pollution from First World countries started to decrease, it also has to do with the different residence time of CO2 and of sulfate aerosols in the atmosphere.

Not exact matches

The results imply that the interaction between organic and sulfuric acids promotes efficient formation of organic and sulfate aerosols in the polluted atmosphere because of emissions from burning of fossil fuels, which strongly affect human health and global climate.

Ironically, if the world burns significantly less coal, that would lessen CO2 emissions but also reduce aerosols in the atmosphere that block the sun (such as sulfate particulates), so we would have to limit CO2 to below roughly 405 ppm.

Aerosols are solid or liquid particles suspended in the atmosphere, consisting of (in rough order of abundance): sea salt, mineral dust, inorganic salts such as ammonium sulfate (which has natural as well as anthropogenic sources from e.g. coal burning), and carbonaceous aerosol such as soot, plant emissions, and incompletely combusted fossil fuel.

That's far from the worst flaw in his calculation, since his two biggest blunders are the neglect of the radiative cooling due to sulfate aerosols (known to be a critical factor in the period in question) and his neglect of the many links in the chain of physical effects needed to translate a top of atmosphere radiative imbalance to a change in net surface energy flux imbalance.

I'd like to learn whether or not spraying sulfate aerosols high in the atmosphere to mitigate global warming will significantly enhance the probability of acid rain.

Do you mean simulations isolating sulfate and nitrate aerosols or do you mean simulations isolating CFCs (Chlorofluorocarbons), a relatively unimportant greenhouse gas - due to its relatively extremely low concentrations in the atmosphere?).

In my mind, the most serious peril of sulfate geoengineering is one that stems from a problem that is not at all in dispute: the fact that the lifetime of CO2 in the atmosphere is centuries to millennia, whereas the lifetime of aerosols in the stratosphere is at best a few yearIn my mind, the most serious peril of sulfate geoengineering is one that stems from a problem that is not at all in dispute: the fact that the lifetime of CO2 in the atmosphere is centuries to millennia, whereas the lifetime of aerosols in the stratosphere is at best a few yearin dispute: the fact that the lifetime of CO2 in the atmosphere is centuries to millennia, whereas the lifetime of aerosols in the stratosphere is at best a few yearin the atmosphere is centuries to millennia, whereas the lifetime of aerosols in the stratosphere is at best a few yearin the stratosphere is at best a few years.

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.

This cooling was from the same root cause as volcanic cooling, namely aerosols (mostly sulfate aerosols) in the atmosphere.

Real Climate defines «aerosols» as ``... solid or liquid particles suspended in the atmosphere, consisting of (in rough order of abundance): sea salt, mineral dust, inorganic salts such as ammonium sulfate (which has natural as well as anthropogenic sources from e.g. coal burning), and carbonaceous aerosol such as soot, plant emissions, and incompletely combusted fossil fuel.»

Meanwhile, production of greenhouse gases — which linger in the atmosphere much longer than sulfate aerosols — has continued, causing average global temperatures to rise.

The Sulfate cooling mechanism is also evidenced whenever there is a high ejecta mass volcanic eruption, which causes a measurable cooling effect, for about 3 years after an eruption; until the sulfate particulate aerosols diminish in the atmosphere to the point that they become neglSulfate cooling mechanism is also evidenced whenever there is a high ejecta mass volcanic eruption, which causes a measurable cooling effect, for about 3 years after an eruption; until the sulfate particulate aerosols diminish in the atmosphere to the point that they become neglsulfate particulate aerosols diminish in the atmosphere to the point that they become negligible.

They can either be directly emitted into the atmosphere (primary aerosols like dust), or they can be formed in the atmosphere by condensation (secondary aerosol like sulfates).

Volcanic eruptions emit sulfate aerosols via volcanic plumes, which may stay in the stratosphere for months to years, reflecting sunlight back into space, cooling the Earth's lower atmosphere or troposphere over a long time...
