Sentences with phrase «from human aerosol emissions»

In other words, the slowed surface warming isn't a result of a smaller global energy imbalance due to factors like increased cooling from human aerosol emissions.

There is a fairly large degree of uncertainty in these figures, primarily because the magnitude of the cooling effect from human aerosol emissions is not well known.

The 2007 report focussed on greenhouse gasses, he said, whereas the 2013 report included all «anthropogenic forcings», including «the cooling effect from human aerosol emissions».

Greenhouse gases can be attributed to about 0.9 °C of this warming, but it has been partially offset by about 0.3 °C cooling from human aerosol emissions.

Not exact matches

China «could cause some decreases [in stratospheric aerosols] if that is the source,» Neely says, adding that growing SO2 emissions from India could also increase cooling if humans are the dominant cause of injecting aerosols into the atmosphere.

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.

Aerosol particles come from many sources, including human emissions.

When aerosols from human activities such as industrial plant and vehicle emissions are added to the system, the energy budget has to deal with the increase.

Analyses of the ground and aircraft data performed by Setyan et al. (2012), Shilling et al. (2013), and Kleinman et al. (2016) showed that organic aerosol production increased when human - caused emissions from Sacramento mixed with air rich in isoprene, an organic compound wafting from many plants that originate in the area's foothills.

Scientists found that emissions of tiny air particles from human - made sources — known as anthropogenic aerosols — were the cause.

Somewhere there should also be a cost in human health bill for coal and gas — related to other aspects of fossil fuel epidemiology — like poisoning from mercury from coal emissions or asthma from aerosols from gas plants.

We have recently discussed several papers which have found substantial global dimming as a result of increased human aerosol emissions from 1950 to 1980 and 2000 to 2010.

The black line, reconstructed from ISCCP satellite data, «is a purely statistical parameter that has little physical meaning as it does not account for the non-linear relations between cloud and surface properties and planetary albedo and does not include aerosol related albedo changes such as associated with Mt. Pinatubo, or human emissions of sulfates for instance» (Real Climate).

The identification of other, sometimes more powerful, greenhouse gases such as methane, the contributions to atmospheric carbon dioxide from other human activities such as deforestation and cement manufacture, better understanding of the temperature - changing properties of atmospheric pollution such as sulphur emissions, aerosols and their importance in the post-1940s northern hemisphere cooling: the knowledge - base was increasing year by year.

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).

As stated earlier, I agree with the point that tropospheric aerosols from fossil fuels are incredibly bad for human health and other environmental impacts (black carbon soot, acid rain, radioactive emissions, mercury poisoning), putting us in a situation of damned if we do, damned if we don't.

Aerosol particles come from many sources, including human emissions.

The failure to actually reduce global emissions has meant that all possibilities are now on the table, including some that sound like premises from a science - fiction novel: Humans could sequester carbon dioxide by removing it from the air through technologies that mimic trees, or we could spray water droplets in the lower atmosphere to reflect light and heat back to space, or we could seed sulfur aerosols in the stratosphere to do the same.
