Although the study acknowledges that methane sources come from a range of natural and man - made activities — oil extraction, natural gas leaks, wetlands, landfills, warming permafrost — researchers say they found less evidence that the boom in oil and gas production is the primary driver of the spike.

The translation is that the little bugs that make methane in swamps get out - competed by other bugs that like acid rain (which is related to sulphate aerosols — mainly from power stations)-- so more industrial pollution, less methane emission (everything else being equal).

Makemake is very much a Pluto analog — it has both methane and nitrogen detected on the surface, but unlike Pluto there is less nitrogen, so more methane atoms are in contact with each other.

It is less prevalent than carbon dioxide in the atmosphere but also more potent: A molecule of methane results in more warming than a molecule of carbon dioxide.

Periods of volcanism can cool the climate (as with the 1991 Pinatubo eruption), methane emissions from increased biological activity can warm the climate, and slight changes in solar output and orbital variations can all have climate effects which are much shorter in duration than the ice age cycles, ranging from less than a decade to a thousand years in duration (the Younger Dryas).

The production of methane is accelerated because stationary pools of water contain much less oxygen than a flowing river interacting with the atmosphere and microbes thrive in low - oxygen environments.

Moreover, even if methane leakage were to remain modest in some areas, long - term climate models suggest that warming trends have less to do with the rate of methane leakage and more to do with other variables, such as the thermal efficiency of future coal plants and whether the switch to gas is permanent or a bridge to zero - carbon energy.

In contrast, greenhouse gases like CO2 and methane have a global influence, which is less regionally different.
