«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.

Even without figuring these surprising methane emissions, I think these fuels may possibly entail greater GHG emissions than they offset — in the manufacture of pesticides, fertilizers, farm equipment; irrigation water & energy to pump it; transporation of bauxite from S. America (harming rainforests) to make farm equipment, ag schools, secretaries, and all the paper work at each stage... the list goes on & on & on.

And finally, what about Mark's questions (# 3) and other factors not discussed here — do all these effects re Arctic ice lead scientists to believe there is a greater and / or earlier chance (assuming we continue increasing our GHG emissions — business as usual) of melting hydrates and permafrost releasing vast stores of methane into the atmosphere than scientists believed before the study, or is the assessment of this about the same, or scientists are not sure if this study indicates a greater / lesser / same chance of this?

point out that isotopic composition of airborne methane has become lighter since 2008, indicating greater wetland / ruminant emission.

Let's err on the side of flamboyance (great word in this context) and say the concentration of methane in the air goes up by a factor of 10 for the duration of the extra methane emission (meaning that the lifetime doubles).

And finally, what about Mark's questions (# 3) and other factors not discussed here — do all these effects re Arctic ice lead scientists to believe there is a greater and / or earlier chance (assuming we continue increasing our GHG emissions — business as usual) of melting hydrates and permafrost releasing vast stores of methane into the atmosphere than scientists believed before the study, or is the assessment of this about the same, or scientists are not sure if this study indicates a greater / lesser / same chance of this?

Because of methane's greater greenhouse potency, the warming potential of the emissions measured during the second period greatly exceeded the potential cooling produced by the uptake of carbon dioxide during photosynthesis.

Subtitle C: Additional Greenhouse Gas Standards -(Sec. 331) Amends the CAA to require the EPA Administrator to promulgate New Source Performance Standards (NSPSs) under such Act for specified categories of stationary sources that: (1) have uncapped GHG emissions greater than 10,000 tons of carbon dioxide equivalent and are responsible for emitting at least 20 % of the uncapped GHG gas emission annually; or (2) are responsible for at least 10 % of the uncapped methane emissions.

But the findings of the Alberta study clearly suggest that actual methane emissions from the upstream oil and gas sector (excluding mined oil sands) are likely to be at least 25 to 50 per cent greater than estimated.

He also found that some of those animals, cows in particular, emit a great deal of methane which is a very potent greenhouse gas emission.

The IPCC Third Assessment Report projections for atmospheric methane concentrations, CO2 emissions and atmospheric concentrations, and resultant temperature increases (i.e. 1.4 to 5.8 degrees Celsius from 1990 to 2100) constitute the greatest fraud in the history of environmental science:

«Humans added plenty greenhouse gases before industrialisation» The author's quote methane emissions annually were greater during the Roman Period than that of all the current world landfill sites.

The tar sands in Canada are an environmental disaster in other ways, but the incremental emissions of greenhouse gases are small compared to the far greater threat of massive coal expansion in China, or potential fugitive emission of methane from fracking, or massive deforestation in Indonesia and Latin America, or any number of other major sources of greenhouse gases.

In my opinion, eating vegetarian results in a greater production of methane emissions.

gain off - topic, but this happens to be about what happened at a particular time long ago of great inerest to me: Higher Wetland Methane Emissions Caused by Climate Warming 40,000 Years Ago http://www.sciencedaily.com/releases/2010/06/100624144105.htm

The study found evidence of even greater discrepancies in individual sectors; methane emissions from livestock, for example, were estimated at twice the level estimated by EPA.

The authors estimated that the region's methane emissions were 3.7 million metric tons of CO2 equivalent, almost five times greater than the 0.75 million metric tons previously estimated (according to the study, methane emissions from oil and gas operations are 2.3 - 7.5 times greater than earlier estimates).

But it was the oil and gas sector — the largest source of methane emissions in the United States — where the variance was greatest, and which is the greatest cause for concern.

Overall, the study found that methane emissions from all U.S. sources — including agriculture, oil and gas development, landfills, and coal mining — are 50 percent greater than estimates from the EPA Inventory, which recently lowered its estimate of methane emissions from oil and gas systems.

But it seems pretty clear that small - scale urban farm biogas digestion has great potential for gleaning energy from urban waste streams, recapturing valuable nutrients and returning them to the soil, and of course keeping rotting matter out of landfills7mdash; preventing both methane emissions and leaching in the process.

That ESAS lacks Mars» mound - density makes the scaling no less valid, the methane - supersaturation of 80 % of ESAS bottom waters (Shakhova et al., 2010) showing that frost mounds are not the sole venting pathway, gas migration pathways growing in capacity annually in the areas of greatest emissions (Shakhova et al., 2017).

Indeed, according to the EPA, so - called «enteric fermentation» in cows and other ruminant animals, like sheep and goats, contributed 26 percent of the country's total emissions of methane, a hard - hitting greenhouse gas with much greater short term warming consequences than carbon dioxide does (though the latter packs a far greater long - term punch).
