Sentences with phrase «decreasing emissions of methane»

Not exact matches

If global levels of hydroxyl decrease, global methane concentrations will increase — even if methane emissions remain constant, the researchers say.

«The overall significance is that although we already know that reducing methane emissions can bring great societal benefits via decreased near - term warming and improved air quality, and that many of the sources can be controlled at low or even negative cost, we still need better data on emissions from particular sources,» Duke University climate sciences professor Drew Shindell said.

From the Physical Science Basis: «Shindell et al. (2009) estimated the impact of reactive species emissions on both gaseous and aerosol forcing species and found that ozone precursors, including methane, had an additional substantial climate effect because they increased or decreased the rate of oxidation of SO2 to sulphate aerosol.

I am struck by «if emissions of methane to the atmosphere were decreased then concentrations of methane in the atmosphere would soon begin to decrease».

Thus, if emissions of methane to the atmosphere were decreased then concentrations of methane in the atmosphere would soon begin to decrease.

Next month, EPA will start a formal process to require companies operating existing methane emissions sources to provide information to assist in development of comprehensive standards to decrease methane emissions.

With fewer solids there is a decrease in anaerobic decomposition and a reduction in the production of methane emissions.

This shows U.S. emissions of methane from the natural gas sector decreased noticeably during one of the largest increases in natural gas production in the nation's history.

The EPA's annual draft inventory of U.S. greenhouse gas emissions report released in April shows that methane emissions from all petroleum systems decreased by over 28 percent since 1990 — including a decrease of emissions from petroleum production of around 8 percent from 2014 levels.

Also note that human induced warming probably will trigger natural C02 / methane emissions leading to further warming so anthropogenic source will probably play a decreasing role in the amount of C02 in the atmosphere as the planet moves to a new equilibrium point.

However, the chemistry of this process is highly non-linear, and as emissions increase, the capacity of the atmosphere to deal with the excess methane decreases and the residence time lengthens.

The effect of this increase on the growth rate of atmospheric methane has been masked by a coincident decrease in wetland emissions, but atmospheric methane levels may increase in the near future if wetland emissions return to their mean 1990s levels.

Times of war and plague when large population losses could have reduced anthropogenic emissions are coincident with short periods of decreasing global methane concentrations.»

New research published in Nature Climate Change shows that as the world warms it both increases the methane emissions from rice paddies, and decreases the crop yield of rice (something which TreeHugger has previously covered).

Of these, policies aimed at renewable energy, CHP, reduction of nitrous oxide from industry and reducing methane emission from landfills produced the largest decreaseOf these, policies aimed at renewable energy, CHP, reduction of nitrous oxide from industry and reducing methane emission from landfills produced the largest decreaseof nitrous oxide from industry and reducing methane emission from landfills produced the largest decreases.

Methane is a transient gas in the atmosphere, so it ought to plateau if the emission flux is steady, but the shape of the concentration curve suggested some sudden decrease in the emission rate, stemming from the collapse of economic activity in the former Soviet bloc, or by drying of wetlands, or any of several other proposed and unresolved explanations.

Nevertheless, our calculations suggest that decreased methane emissions caused by the extinction of the New World megafauna could have played a role in the Younger Dryas cooling event.
