Sentences with phrase «levels of aerosols in the atmosphere»

The increased CO2 will behave exactly the same regardless of the levels of aerosols in the atmosphere, changing the energy balance and warming the planet.

Not exact matches

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.

And while researchers are still striving to fully understand the health and environmental impact of increased levels of secondary organic aerosols in the atmosphere, studies have linked exposure to outdoor aerosols generally to morbidity and mortality outcomes.

During ISDAC, they collected an unprecedented level of data and detailed observations on Arctic clouds and aerosols, those tiny particles in the atmosphere that act as seeds for cloud droplets and ice crystals.

The war period and rapid economic growth that followed resulted in very high levels of heat blocking aerosols in the atmosphere.

I'm pretty sure you can get the grey version of that into a strat - cooling / trop - warming situation if you pick the strat absorbers right, but Andy is certainly right that non-grey effects play a crucial role in explaining quantitatively what is going on in the real atmosphere (that's connected with the non-grey explanation for the anomalously cold tropopause which I have in Chapter 4, and also with the reason that aerosols do not produce stratospheric cooling, and everything depends a lot on what level you are looking at).

The second study meanwhile looked at how aerosol emissions impact the Earth's temperature through a phenomenon the researchers call «transient climate sensitivity,» or how much of the Earth's temperature will change when the amount of carbon dioxide in the atmosphere reaches twice its level during the pre-industrial times.

How do we know what levels of aerosols existed in what zones of the atmosphere going back into history?

Nations collectively to begin to reduce sharply global atmospheric emissions of greenhouse gases and absorbing aerosols, with the goal of urgently halting their accumulation in the atmosphere and holding atmospheric levels at their lowest practicable value;

One hears of dire predictions of sea - level rises which don't seem to be eventuating, of stasis in global temperatures that weren't predicted, of claimed ad - hoc appeals to aerosol effects, etc., and that's without going into the general atmosphere of hostility to people like me who genuinely think the case for harmful AGW effects looks shaky.

Natural Variability Doesn't Account for Observed Temperature Increase In it's press release announcement, NASA points out that while there are other factors than greenhouse gases contributing to the amount of warming observed — changes in the sun's irradiance, oscillations of sea surface temperatures in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed since 188In it's press release announcement, NASA points out that while there are other factors than greenhouse gases contributing to the amount of warming observed — changes in the sun's irradiance, oscillations of sea surface temperatures in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed since 188in the sun's irradiance, oscillations of sea surface temperatures in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed since 188in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed since 188in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed since 188in the atmosphere — these factors are not sufficient to account for the temperature increases observed since 1880.

This temperature plateau is very likely due to increased levels of particulates (or «aerosols») in the atmosphere reflecting solar radiation back into space.
