Sentences with phrase «how aerosol emissions»
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.

But if the decrease in aerosols is driving the brightening trend and the yield increase, there's a limit to how low those emissions can get.
The results show for the first time for a number of natural compounds, which together account for around 70 per cent of the biological hydrocarbon emissions, how much each compound produces low - volatility products and how they can possibly affect the climate via producing aerosol particles.
Differences in how a model represents space and time scales, emission rates, meteorology, gas - phase chemistry, and other aerosol processes all affect model predictions.
Some question remains as to how much of the temporary slowdown in surface warming is due to human aerosol emissions, how much due to ENSO, how much due to heat being transferred to the deep oceans, and so forth.
This relationship between cumulative emissions and warming is not perfect, as it will change based on what happens to non-CO2 greenhouse gases, such as methane and nitrous oxide, as well as how quickly climate - cooling aerosols are reduced.
And exactly how much global warming is being offset by human aerosol emissions?
This also depends on how our aerosol and soot emissions change in the future.
Worse, you have to know aerosol emissions as a function of not just time, but of latitude also, because how much sunlight they reflect depends on the angle of sunlight that impacts them.
It is uncertain how a given emissions path converts into atmospheric concentrations of the various radiatively active gases or aerosols.
«Because there is considerable uncertainty in current understanding of how the climate system varies naturally and reacts to emissions of greenhouse gases and aerosols, current estimates of the magnitude of future warming should be regarded as tentative and subject to future adjustments (either upward or downward).»
«About» ought to be in italics because we really don't know how much cooling is caused by other emissions, like particulate aerosols that go up the smokestack along with the carbon dioxide.
