Sentences with phrase «much methane lifetime»

Not exact matches

The lifetime of methane is about 10 years which is much less than CO2.

The release of this trapped methane is a potential major outcome of a rise in temperature; it is thought that this is a main factor in the global warming of 6 °C that happened during the end - Permian extinction as methane is much more powerful as a greenhouse gas than carbon dioxide (despite its atmospheric lifetime of around 12 years, it has a global warming potential of 72 over 20 years and 25 over 100 years).

I think I know what you mean here but in the context of the previous Much Ado about Methane article with discussion of the difference between atmospheric lifetime of a CO2 molecule vs. lifetime of an increase in concentration, this could also be put more clearly.

He estimated that as much as 8 percent of the methane in shale gas leaks into the air during the lifetime of a hydraulic shale gas well — up to twice what escapes from conventional gas production.

Methane has a 9 year lifetime and just doesn't build up much in the atmosphere.

Since a sustainable future based on the continued extraction of coal, oil and gas in the «business - as - usual mode» will not be possible because of both resource depletion and environmental damages (as caused, e.g., by dangerous sea level rise) we urge our societies to -LSB-...] Reduce the concentrations of warming air pollutants (dark soot, methane, lower atmosphere ozone, and hydrofluorocarbons) by as much as 50 % [and] cut the climate forcers that have short atmospheric lifetimes.

If, on the other hand, a methane release to the atmosphere continues for much longer than the methane lifetime, the concentration of methane in the atmosphere will rise to a new steadystate value.

Methane's lifetime in the atmosphere is much shorter than carbon dioxide (CO2), but CH4 is more efficient at trapping radiation than CO2.

For example, the direct radiative effect of a mass of methane is about 84 times stronger than the same mass of carbon dioxide over a 20 - year time frame [22] but it is present in much smaller concentrations so that its total direct radiative effect is smaller, in part due to its shorter atmospheric lifetime.

Although methane is classed as a long - lived GHG, its lifetime is only of the order of a decade, so it presents much less of a long term problem than CO2, part of which is expected to remain in the atmosphere for 1000 + years.
