Sentences with phrase «reducing aerosol emissions»

Not exact matches

Indeed, the reduction in the emission of precursors to polluting particles (sulphur dioxide) would diminish the concealing effects of Chinese aerosols, and would speed up warming, unless this effect were to be compensated elsewhere, for instance by significantly reducing long - life greenhouse gas emissions and «black carbon.»

Ironically, if the world burns significantly less coal, that would lessen CO2 emissions but also reduce aerosols in the atmosphere that block the sun (such as sulfate particulates), so we would have to limit CO2 to below roughly 405 ppm.

Beyond reducing the volume of acidic particles in aerosols, cutting the sulfur emissions has also reduced the deposition of acids in lakes and waterways, noted Armistead «Ted» Russell, a Regent's Professor in Georgia Tech's School of Civil and Environmental Engineering and another of the paper's co-authors.

Li said the study's findings should further spur countries like China and India to cut aerosol emissions so they reduce pollution and thereby increase their solar electricity generation more rapidly, in addition to the already known health benefits.

Professor Sybren said: «It can be excluded, however, that this hiatus period was solely caused by changes in atmospheric forcing, either due to volcanic eruptions, more aerosols emissions in Asia, or reduced greenhouse gas emissions.

Or maybe can the chance distribution of the aerosol forcing (main emissions moved from US / Europe to Asia f.e.) used to reduce the uncertainty of the size of the aerosol forcing or the factor E?

Within the timescales in which the aerosols will be reduced, we can / could also see reduced CH4 emissions and N2O emissions which will lead to lower GHG forcing in years rather than decades.

Reducing sulfur emissions also stops the cooling impact of sulfate aerosols.

However, as I understand it what is currently the mainstream view is that what explains the transition from early 20th century warming to the flat period between is the resumption of industrial production and thus of reflective aerosols (predominantly sulfates), and that likewise, it was the passage in the early seventies of laws requiring cleaner emissions that reduced reflective aerosols.

It is likely that at least some of this change, particularly over Europe, is due to decreases in pollution; most governments have done more to reduce aerosols released into the atmosphere that help global dimming instead of reducing CO2 emissions.

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.

These scenarios presume that there are no major volcanic eruptions and that anthropogenic aerosol emissions are rapidly reduced during the near term.

(Sec. 333) Requires the EPA Administrator to promulgate regulations to reduce emissions of black carbon (light absorbing aerosols) or propose a finding that existing CAA regulations adequately regulate such emissions.

Now, the only way that a business recession could cause a temporary rise in average global temperatures is for the reduced industrial activity to result in a reduction in the amount of SO2 aerosol emissions into the troposphere.

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;

«This study has demonstrated for the first time, using in - situ PM measurements, that reducing aerosol pollution is driving the Insolation Brightening phenomenon and that the trends in aerosol pollution, particularly for sulphate aerosol, is directly linked to anthropogenic emissions.

In addition, the weakening of the RF of sulphate aerosol in many regions due to reduced emissions (Section 2.4.4.1) will be partially balanced by increases in the RF of nitrate aerosol (e.g., Liao and Seinfeld, 2005).

[note] In this context it intrigues me that those who advocate for stratospheric aerosol injection (SAI) tend to ignore the possibility that the possible termination effect would increase net risk from greenhouse gas emissions, and the deployment of SAI should therefore (in risk adjustment terms) justify accelerated mitigation rather than reduced mitigation.

The control knob for climate change is the amount of dimming sulfur dioxide aerosol emissions in the atmosphere — the fewer there are, the warmer it gets — and we are reducing them as fast as we can, thanks to the EPA.

«Comparing the amount of warming in the U.S. saved by reducing our greenhouse gas emissions by some 80 % to the amount of warming added in the U.S. by increases in Asian black carbon (soot) aerosol emissions (at least according to Teng et al.) and there is no clear winner.

Sulphur emissions from fossil fuel combustion lead to the formation of aerosols that affect regional climate and precipitation patterns and also reduce radiative forcing.

The sixth possible component, only to be used as a last resort, would be some form of geo - engineering to probably replace the aerosols that would be lost as carbon emissions are reduced and do not replace the short - term aerosols.

On one hand, the reduction in global SO2 emissions reduces the role of sulfate aerosols in determining future climate toward the end of the 21st century and therefore reduces one aspect of uncertainty about future climate change (because the precise forcing effect of sulfate aerosols is highly uncertain).

Results of this measurement campaign indicate that alcohol fuels (E85, E100) significantly reduce both primary particulate emissions as well as subsequent secondary aerosol formation in the atmosphere when compared emissions of gasoline fuels.

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.
