pingo

Filed under: Uncategorized — Elizabeth @ 12:02 pm

Realizing exploding pingos could quickly change our warming situation*…I wondered is ignorance bliss? Then I’m realizing as I gain awareness there are moments of astonishment at how beautiful the stunning nature of this blue sky moment is. It becomes more clear – the miracle of this peaceful and exquisite moment right now. Thich Nhat Hanh’s peaceful speaking makes sense. You can listen to him on youtube. Knowing how precious and rare this amazing moment is, it becomes so embraceable. When we pretend that enough water or food or whatever will protect us from our vulnerability we forget our existence. Cultivating compassion and peace seems worthwhile then. We have a civic responcibility to put social values, to put environmental values into the economy; market fundamentalism – just let the free market do it’s thing, will not solve this. That requires government. (Yale, James Gustave Speth, 2004). IMO the physicists will be gaining us some more time on the planet by being the brains behind geoengineering(which we’ll suddenly be allowed to talk about and which will suddenly be receiving tons of research money). It’s not the ideal way but I bet it’s what we’ll have. If you put a ton of sulfur into the air (like a volcano does) you will cool the planet and it can be done cheaply. Also you can biodigest oil and coal instead of burning it to process it.

Wikipedia: methane clathrate
…Methane hydrates were discovered in Russia in the 1960s, and studies for extracting gas from it emerged at the beginning of the 21st century.[4]…

The sudden release of large amounts of natural gas from methane clathrate deposits has been hypothesized as a cause of past and possibly future climate changes. Events possibly linked in this way are the Permian-Triassic extinction event and the Paleocene-Eocene Thermal Maximum.

Climate scientists like James E. Hansen predict that methane clathrates in the permafrost regions will be released because of global warming, unleashing powerful feedback forces which may cause runaway climate change that cannot be halted.[citation needed]

Research carried out in 2008 in the Siberian Arctic found millions of tonnes of methane being released[41][42][43][44][45] with concentrations in some regions reaching up to 100 times above normal.[46]

In their Correspondence in the September 2013 Nature Geoscience journal, Vonk and Gustafsson cautioned that the most probable mechanism to strengthen global warming is large-scale thawing of Arctic permafrost which will release methane clathrate into the atmosphere.[47] While performing research in July in plumes in the East Siberian Arctic Ocean, Gustafsson and Vonk were surprised by the high concentration of methane.[48]

In 2014 based on their research on the northern United States Atlantic marine continental margins from Cape Hatteras to Georges Bank, a group of scientists from the US Geological Survey, the Department of Geosciences, Mississippi State University, Department of Geological Sciences, Brown University and Earth Resources Technology, claimed there was widespread leakage of methane.[49][50]

Scientists from the Center for Arctic Gas Hydrate (CAGE), Environment and Climate at the Arctic University of Norway, published a study in June 2017, describing over a hundred ocean sediment craters, some 3,000 meters wide and up to 300 meters deep, formed due to explosive eruptions, attributed to destabilizing methane hydrates, following ice-sheet retreat during the last glacial period, around 12,000 years ago, a few centuries after the Bølling-Allerød warming. These areas around the Barents Sea, still seep methane today, and still existing bulges with methane reservoirs could eventually have the same fate.[51]

*Wikipedia: Clathrate gun hypothesis
Research carried out in 2008 in the Siberian Arctic has shown millions of tons of methane being released, apparently through perforations in the seabed permafrost,[20] with concentrations in some regions reaching up to 100 times normal levels.[22][23] The excess methane has been detected in localized hotspots in the outfall of the Lena River and the border between the Laptev Sea and the East Siberian Sea. Some melting may be the result of geological heating, but more thawing is believed to be due to the greatly increased volumes of meltwater being discharged from the Siberian rivers flowing north.[24] Current methane release has previously been estimated at 0.5 Mt per year.[25] Shakhova et al. (2008) estimate that not less than 1,400 Gt of carbon is presently locked up as methane and methane hydrates under the Arctic submarine permafrost, and 5–10% of that area is subject to puncturing by open taliks. They conclude that “release of up to 50 Gt of predicted amount of hydrate storage [is] highly possible for abrupt release at any time”. That would increase the methane content of the planet’s atmosphere by a factor of twelve,[26][27] equivalent in greenhouse effect to a doubling in the current level of CO2.
