The phrase
"to increase the methane" means to make the amount of methane gas larger or higher.
Full definition
In the longer - term, a crucial question that remains is whether methane oxidation in natural environments can match potentially
increased methane production in response to predicted climate change.
Note that
increased methane also leads to increased ozone concentrations, for added radiative forcing bang for your methane buck.
My belief, reinforced by recent, and as yet unpublished, research by University of Alaska Fairbanks scientists, is that we have just entered the phase of super-exponentially
increasing methane releases from the Arctic.»
Sorry to veer off topic slightly but this is a request that the good folk of realclimate consider offering their perspective on the news about
increasing methane levels.
A Primer On Methane Leaking From The East Siberian Shelf Reaction to the news that there is
increased methane leaking from the seafloor on the East Siberian Shelf in the Arctic has ranged from near panic to a near impersonation of Alfred E Neuman's «What - Me Worry?»
Opponents raise concerns
about increasing methane gas levels (a powerful greenhouse gas) and other contamination involving the spillover of fracking wastewater in the groundwater of shale - rich regions.
But because there's not much methane to begin with, it's not true that 1.33 x methane has more impact than a doubling of CO2 (we've already
increased methane by well over this amount)... a doubling of methane doesn't even have nearly as much impact as a doubling of CO2.

«With
increased methane into the atmosphere, the climate gets warmer faster, and early on it has a more intense effect on the whole climate.»
Isotope Data Suggests Fossil Fuels Not to Blame for
Increase Methane bubbles up from swamps and rivers, belches from volcanoes, rises from wildfires, and seeps from the guts of cows and termites (where is it made by microbes).
Half of the cultured algae can be pumped down within the landfill to
further increase methane output, while the other portion of algae could go toward creating biodiesel fuels.
The study suggests that future warming in the Arctic could expand the active layer and
increase methane transport to lakes, and from lakes into the atmosphere, exacerbating global warming.
Dairy manure mixed with no biochar and 0.1 - 1 percent biochar showed that adding
biochar increased methane production by approximately 40 percent and reduced the production time to achieve target biogas production by 50 - 70 percent.
So I think it's really a testament to how far lost the environmental movement is that so many of these groups have signed off on this deal that would
increase methane leaks, increase carbon pollution.
Since methane is a greenhouse gas 25 times as potent as carbon dioxide, such a scenario would trigger a «climate catastrophe», they say,
increasing the methane content of the planet's atmosphere twelve-fold, and raising temperatures by 1.3 ˚C.
Indeed,
increased methane emissions lead to decreased hydroxyl concentrations, but it isn't a straightforward calculation to determine exactly how much hydroxyl disappears, or how much methane lifetime increases due to that.
Methane gas released from the seabed during the summer months leads to
an increased methane concentration in the ocean.
I sent a comment encouraging Real Climate to blog on
the increasing methane levels papet that seems to be getting a bit of press but I supplied the wrong link.
The impact of policies which involve trade - offs between one GHG and another (such as replacing coal with natural gas, which would reduce CO2 but might
increase methane emissions) is especially uncertain, since current models of both gases» life - cycles (and thus their relative GWPs) may need to be revised in the future.
Likely impacts include large - scale disintegration of the Greenland and West Antarctic ice - sheet; the extinction of an estimated 15 — 40 per cent of plant and animal species; dangerous ocean acidification;
increasing methane release; substantial soil and ocean carbon - cycle feedbacks; and widespread drought and desertification in Africa, Australia, Mediterranean Europe, and the western USA.
«A higher feed intake will
increase methane production.
«Science is unable to keep up with the rate of change in the climate, the arctic heating and melting, and
the increasing methane emissions.
Whether climate change will
increase methane emissions will depend on soil moisture, said Professor Turetsky.
The researchers found that these effects are linked to
increased methane emissions from peat with higher bulk densities.
Most studies also point to
increased methane emissions from wetlands in a warmer, wetter climate (Denman et al., 2007 Section 7.4.1.2).
Methane gas released from the Arctic seabed during the summer months leads to
an increased methane concentration in the ocean.
«I really think it's really a testament to how far lost the environmental movement is that so many of these groups have signed off on this deal that would
increase methane leaks, increase carbon pollution,» Shellenberger says.
