Sentences with phrase «triggered by the methane»

Although there is not yet proof the warming was triggered by the methane release, Cossey said the timing fits.

Time was of the essence as California governor Jerry Brown declared a state of emergency with the California Public Utilities Commission (CPUC), California Energy Commission and California Independent System Operator (CAISO) clubbing together to address the energy shortages triggered by the methane leak.

Not exact matches

It is entirely possible that a random triggering event or series of events (lightning or some form of electricity charging a primordial soup of methane, ammonia, etc.; bombardment by cosmic radiation and other hypothetically random occurrences) was the occasion through which a whole new dimension, that of the biosphere, flooded onto the terrestrial scene.

Changes in ocean currents, Kennett says, triggered the methane bursts by channeling warmer water over continental slopes, as at Storegga.

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.

Once formed by either serpentinization or microbes, methane could be stored as a stable clathrate hydrate — a chemical structure that traps methane molecules like animals in a cage — for later release to the atmosphere, perhaps by gradual outgassing through cracks and fissures or by episodic bursts triggered by volcanism.

Once produced, methane could have been stored as a stable clathrate hydrate and released to the atmosphere either gradually, through volcanism, or in bursts, triggered by impacts.

Might future exploding methane domes, triggered by melting ice, release extra methane into the atmosphere?

Simple biogeochemical flux modeling suggests that, if the Archean Earth was kept warm by a methane greenhouse, then the evolution of oxygenic photosynthesis could have triggered a Snowball Earth event on a time scale as short as about a million years (Kopp et al., 2005).

Even CO2 which is a better greenhouse gas than methane (when comparing them side - by - side in equal concentrations) does not trigger a runaway greenhouse, even in studies where it becomes the substantial part of the atmosphere.

One should also pay attention to other greenhouse gases, particularly methane (from rice paddies, ruminant animal digestive processes, industrial processes, and distributed natural sources, some of which could be triggered to large releases by warming) and nitrous oxide (from the nitrogen cycle linking the atmosphere, plants, and bacteria, now exacerbated by extremely heavy use of nitrogenous fertilizers in agriculture; note, as does Vaclav Smil from the University of Manitoba, that fertilizer use is required to feed half the world's current population.

«Earthquakes trigger methane release, and consequent warming of the planet triggers earthquakes, as reported by Sam Carana at the Arctic Methane Emergency Group (October 2013)methane release, and consequent warming of the planet triggers earthquakes, as reported by Sam Carana at the Arctic Methane Emergency Group (October 2013)Methane Emergency Group (October 2013)»

Sediment samples gathered in south Australia led Kennedy's team to theorize that a catastrophic era of global warming was triggered some 635 million years ago by a gradual — and then abrupt — release of methane from frozen soils, bringing an end to «Snowball Earth,» when the entire planet was encrusted in ice.

Bangs, N.L., Hornbach, M.J., Park, J - O, and G.F. Moore, «Massive methane release triggered by seafloor erosion offshore southwestern Japan,» Geology, 38, no. 11, 2010

Tackling methane and soot could reduce the scientists» projections of average warming in 2050 by 40 percent, which could mean the difference between triggering serious feedbacks in the global climate systems or not.

Given the dire consequences of a major methane gas release triggered by ongoing warming the latest science now says that such a release of methane will not happen for several hundred years.

More recently, scientists also have begun to think that a stress reaction triggered by ultra violet light can also cause trees to produce methane.

The mass outpourings of methane, 200 million years ago, could have been triggered by volcanoes pumping out CO2, the scientists think - a situation that may be repeated if man's CO2 emissions trigger a tipping point for today's frozen deep - sea methane.

The most notorious was 252 million years ago; it began when carbon warmed the planet by five degrees, accelerated when that warming triggered the release of methane in the Arctic, and ended with 97 percent of all life on Earth dead.

The slowness of the methane feedback is open to question, given the unprecedentedly rapid and systematic triggering event provided by fossil fuels.

In fact, methane release from the oceanic hydrates perhaps triggered by flood basalt eruptions, could be a general explanation for most mass extinction events.

The threat of global warming amplifying itself by triggering massive methane releases is real and may already be under way, providing plenty of fodder for scary headlines.

During the glacial cycles of the past 800,000 years both CO2 and methane have acted as important amplifiers of the climate changes triggered by variations in Earth's orbit around the Sun.

My understanding is that the atmosphere warmed by about 6 degrees C from our current level, and that triggered increasing releases of methane from clathrates in a positive feedback fashion over thousands of years (or was it millions of years??).

The Report identified 19 major environmental tipping points that are at risk of being triggered by processes linked to climate change, including higher releases of methane, and collapse of key Arctic fisheries.
