When it comes to predicting the future course of climate change, therefore, «these kinds of scenarios regarding natural methane are not as important to take into account,» he says.

Their investigation could also help answer one of the questions everybody else is asking: just how much oil has been released?John Kessler, of the Department of Oceanography at Texas A&M; University in College Station, has dedicated his life to understanding the effect of natural methane seepage on global climate.

But the burst well has also become an unlikely scientific windfall for Kessler, who studies natural methane seeps and their link to rapid climate change.

A US study from 2011 showed high levels of methane in water wells close to shale gas wells, but has been criticised for lacking data on levels of background natural methane in the water.

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

Natural methane hydrates were first discovered by Russian scientists in the late 1960s in Siberian permafrost — where the ground is so cold that hydrates can form at shallower depths and at lower pressures than under the sea — and then, in the 1970s, at the bottom of the Black Sea.

A future hydrogen economy could use the gas as an energy carrier As this method doesn't produce oxygen which needs to be kept separate from hydrogen, safety from explosion of the two gases is much less of a problem with electricity in the national grids carried by ageing cables, it would be useful to replace them by passing the hydrogen along gas pipes used currently for natural methane gas.

[9] However, it is also thought that fresh water used in the pressurization of oil and gas wells in permafrost and along the continental shelves worldwide combines with natural methane to form clathrate at depth and pressure, since methane hydrates are more stable in fresh water than in salt water.

Although climate patterns in the future may not exactly mimic those conditions, the period of warming allowed Petrenko to reveal an important piece of the climate puzzle: natural methane emissions from ancient carbon reservoirs are smaller than researchers previously thought.

Lovely says the discovery of DIET challenges the concept held for decades that natural methane - producing microbial communities primarily exchange electrons through the production and consumption of hydrogen gas.

In less than a handful of cases, the natural methane levels were relatively high, above 10 milligrams per liter.

«We do not need to worry as much about the natural methane seeps into the atmosphere.

I note your point that most of the natural methane release comes from the tropics, so a 100 x increase in Arctic emissions would lead to only a x10 increase in natural methane releases overall.

To get a better look at the natural methane seepage at this site, researchers used a special seismic instrument that can produce 3D images of deep ocean sediments.

There are natural methane and nitrous oxide emissions, but destroying these GHGs will not lead to any adverse consequences to the environment / society because we can reduce removal efforts once their concentrations return to pre-industrial (i.e. sustainable) levels.
