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).

Raymond Pierrehumbert, an Oxford University atmospheric physics professor who believes cutting carbon dioxide emissions is more urgent than cutting methane emissions, said Howarth's research offers little new information about the role of natural gas production in global warming.

Because human - made warming is more rapid than natural long - term warmings in the past, there is concern that methane hydrate or peat feedbacks could be more rapid than the feedbacks that exist in the paleoclimate record.

And then there's methane, a more potent global warming gas than CO2.

For the PETM in particular, the temperature proxies seem to require more warming than a ~ 1 - 2000 Gt C methane spike would generate (with the climate forcing agent being the CO2, as documented by its longevity).

E.g. 550 million years ago CO2 was a whopping 18 times higher than today, and it was significantly warmer, meaning that methane levels must also have been much higher too.

Instead, they stretch out methane's warming impacts over a century, which makes the gas appear more benign than it is, experts said.

On the climate front, discussions of ways to limit global warming seem more focused on capturing stray emissions of methane (more on that anon) than on pressing for ways to promote it as an alternative to coal, at least as a bridge to even less - polluting energy sources.

This is a much more serious scenario than «regular» anthropogenic GW, because the warming could be amplified, eventually thawing methane clathrates, and the warming could then really spiral to an massive extinction event level (as happened 251 million years ago when up to 95 % of life on earth died).

Or, trying to «correct» for the different lifetimes of the gases using Global Warming Potentials, over a 100 - year time horizon (which still way under - represents the lifetime of the CO2), you get that the methane would be equivalent to increasing CO2 to about 500 ppm, lower than 750 because the CO2 forcing lasts longer than the methane, which the GWP calculation tries in its own myopic way to account for.

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).
