Sentences with phrase «aerosol loading as»

Not exact matches

The question is: Does the current load of aerosols in the atmosphere already exceed that limit, in which case adding extra particles should not greatly affect cloud formation; or do they continue to be a limiting factor as pollution rises, so that added aerosols would continue to influence the clouds?

These mercury - free dentists have no safety protocol in place, and as a result, are exposing their patients, their employees and themselves to a heavy load of mercury aerosol each time old amalgam fillings are dr...

SW fails to mention effects that may counter-act warming trends, such as irrigation, better shielding of the thermometers, and increased aerosol loadings, in addition to forgetting the fact that forests were cut down on a large scale in both Europe and North America in the earlier centuries.

The localized cooling between about 1950 and 1970 over industrial regions such as Europe and Southeast Asia, where anthropogenic sulfate aerosol loadings were high, is consistent with the expected cooling effect of sulfate aerosols.

Possible explanations include greenhouse effects such as changes in cloudiness, aerosol loading, atmospheric water vapor content, or carbon dioxide.

Rice cultivation regions show reduced warming as they are concentrated where monsoon rainfall is projected to intensify, although projections are influenced by Asian aerosol loading in climate mitigation scenarios.

«since the mid 1980s a significant increase in visibility has been noted in western Europe (e.g. Doyle and Dorling, 2002), and there are strong indications that a reduction in aerosol load from anthropogenic emissions (in other words, air pollution) has been the dominant contributor to this effect, which is also referred to as «brightening».»

Li et al., 2017 (DOI: 10.1016 / j.quascirev.2017.01.009): «Additionally, increased El Nino - Southern Oscillation (ENSO) strength (possibly El Ni ~ no - like phases) during drying periods, increased volcanic eruptions and the resulting aerosol load during cooling periods, as well as high volumes of greenhouse gases such as CO2 and CH4 during the recent warming periods, may also play a role in partly affecting the climatic variability in NC, superimposing on the overall solar dominated long - term control.»

They accounted for the known orbital forcing and also considered other possible feedbacks, such as the aerosol loading of the atmosphere.

The oceans are also susceptible to aerosol cooling as the ocean surface albedo is low (natural background aerosol loading is also low).

However, if it is forced by time - varying aerosol loadings, it should properly be interpreted as part of an accelerating anthropogenic trend.

There is also a fairly large increase in modelled sulfate load over the Tropical North Atlantic from about 1960, which is presumably the main cause of modelled present day strong aerosol forcing off the West African coast, as depicted in Booth et al. figure 4b.
