Sentences with phrase «aerosol emissions levels»

Pollutant gas and aerosol emissions levels in the reference scenario were checked for consistency by estimating regional surface particulate and ozone levels using the MOZART atmospheric chemistry model.

Not exact matches

The scientists expect further warming in the Arctic as levels of greenhouse gases will continue to increase and aerosol particle emissions will likely decrease to combat air pollution in different parts of the world.
Toxins and nicotine have been measured in that aerosol, such as formaldehyde, acetaldehyde, acetic acid and other toxins emitted into the air, though at lower levels compared to conventional cigarette emissions.
Compared to the past decades, the pattern (more emissions in South Asia) and the relative forcings are completely different, with much less relative influence of aerosols than today (due to faster increasing CO2 levels).
Compared to the past decades, the pattern (more emissions in South Asia) and the relative forcings are completely different, with much less relative influence of aerosols than today (due to faster increasing CO2 levels).
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.
Levels of aerosol emissions have soared since the 1950s, with the most common sources being power stations and cars.
While SO2 emissions may have had some small role in that period, they can't have a role in the current standstill, as the increase of emissions in SE Asia is compensated by the decrease in emissions in the Western world, thus there is hardly any increase in cooling aerosols while CO2 levels are going up at record speed and temperatures are stalled.
«warming in the pipeline» usually assumes constant concentrations, not zero emissions (though if CO2 emissions were dropped to zero tomorrow, and all other emissions were held constant, I'd probably expect a little bit of warming before it turned over and started dropping) 2) Don't forget aerosols: they are following the Level 1 scenario from Wigley et al. 2009, and may actually dominate short - term temperature trends.
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;
Sulfate aerosols wash out pretty quickly, so their current atmospheric concentration (and the resulting negative forcing) is mainly determined by the current emissions levels.
The increase in oxidant levels and preexisting aerosol mass since preindustrial times is the reason of the burden change, since emissions have not changed significantly.
Emissions scenarios were converted to projections of atmospheric GHG and aerosol concentrations, radiative forcing of the climate, effects on regional climate, and climatic effects on global sea level (IPCC, 2001a).
