Sentences with phrase «affected by methane»

Not exact matches

The emission of methane by ruminants is probably not affected by organic production.

The elected officials also called for expanded benzene and methane testing and the creation of a federal health registry to track those potentially affected by the spill.

Of course, the amount of water vapor in the atmosphere is also affected by another potent greenhouse gas — methane — which has unexpectedly failed to increase in recent years.

Based on methane and oxygen distributions measured at 207 stations throughout the affected region, we find that within ~ 120 days from the onset of release ~ 3.0 × 1010 to 3.9 × 1010 moles of oxygen were respired, primarily by methanotrophs, and left behind a residual microbial community containing methanotrophic bacteria.

Like methane emissions, methyl bromide and methyl iodide are affected by growth stages, the organic content of the soil and flooding events.

Another complication is that the concentration of methane and other gases in natural deposits could be affected not just by chemistry but also by the speed at which they seep through the surrounding rocks.

These components — specifically aerosols (particulates in the air — dust, soot, sulphates, nitrates, pollen etc.) and atmospheric chemistry (ozone, methane)-- are both affected by climate and affect climate, since aerosols and ozone can interact, absorb, reflect or scatter solar and thermal radiation.

Almost all of the methane leakage calculated from the Texas research «could be affected by this measurement failure,» according to the paper; «their study appears to have systematically underestimated emissions.»

Reductions in sea ice and other changes may affect the amount of Carbon Dioxide absorbed by the Arctic Ocean, while thawing permafrost is expected to increase emissions of methane.

Major ice sheets, in particular in Greenland [8], ocean methane clathrate deposits [9], and future evolution of glacial / interglacial cycles [10] might be affected by that long tail.

One might expect some clathrate release in the Arctic, perhaps not enough to greatly affect global warming by itself, but add this to the increased thermal energy and methane radiation already on the increase in the Arctic and the combination increases risk.

[Response: The methane correlation is because natural methane emissions are also affected by climate — principally from wetlands.

The biggest natural emitters of methane are wetlands and lakes, both of which are affected by the impacts of climate change, namely increased temperatures and changing hydrology.

The balance between methane production and its oxidation within these environments before it can be released to the atmosphere, both of which are affected by temperature and hydrology, is crucial to understanding the response of these systems to climate change.

The quick warming in the short run catalyzed by methane can affect environmental processes, such as the flowering of plants, she said at the American Geophysical Union meeting last week.

In order of seniority, the seven feedbacks that seem outstanding are: Water vapour — rising by ~ 7 % per 1.0 C of warming; Albedo loss — due mostly to cryosphere decline; Microbial peat - bog decay — due to rising CO2 affecting ecological dynamics; Desiccation of tropical and temperate soils — due to SAT rise and droughts; Permafrost melt — due to SAT rise plus loss of snow cover, etc; Forest combustion — due to SAT rise, droughts, pest responses, etc; Methyl clathrates [aka methane hydrates] now threatened by rising sea - temperatures, increased water column mixing, etc..

Because organisms are affected by climate, the latter has an influence on the recycling, while some of the molecules involved in the recycling, such as carbon dioxide and methane, influence the climate through the greenhouse effect.

We have shown that areas of the ESAS affected by thermokarst [permafrost melting], submerged taliks and some other processes could serve as migration pathways for methane to escape to the water column and further to the atmosphere.»

The methane sink is affected by ozone precursors (VOCs and NOx) as well as directly by climate (humidity and temperature)(in addition to the soil sink feedback you mention), while the sources are also affected by climate — wetland emissions are affected by wetland extent, water tables and temperature, while hydrates (as seen above) are a big unknown.

For example, pollutants such as black carbon (BC), organic carbon (OC), sulfur dioxide (SO2) or methane (CH4), affect human health both by altering climate as CO2 does (hereafter climate - health impacts) but also by more directly degrading air quality (hereafter composition - health impacts).

I account for the time - dependence of the ozone response to methane and CO emissions, and thus these are affected by the discount rate and projected GDP and baseline mortality, which are the same as for climate - health impacts.
