Yedoma
Yedoma is an organic-rich (about 2% carbon by mass) Pleistocene-age loess permafrost with ice content of 50–90% by volume. The amount of carbon trapped in this type of permafrost is much more prevalent than originally thought and may be about 500 Gt, that is almost 100 times the amount of carbon released into the air each year by the burning of fossil fuels. Thawing yedoma is a significant source of atmospheric methane (about 4 Tg of CH
4 per year).
Yedoma currently occupies an area of more than one million square kilometers in northeast Siberia, and in many regions is tens of meters thick. During the Last Glacial Maximum, when the global sea level was 120 m lower than that of today, similar deposits covered substantial areas of the exposed northeast Eurasian continental shelves. At the end of last ice age, at the PleistoceneHolocene transition, thawing yedoma and the resulting thermokarst lakes may have produced 33 to 87% of the high-latitude increase in atmospheric methane concentration.

"To burn the house down with the money in it, to revel in the power of refusing to loot, to strip the soldier of his clothes, put his weapons on the pyre and let him go free, ashamed of his nakedness. " --Ammiel Alcalay, from The Cairo Notebooks, (1993)~more proliferation:Los Alamos Environmental Impact by Willem MaltenWhen over 80% of the American public has expressed a desire for mutual nuclear disarmament and still the US nuclear labs (Los Alamos and Sandia in New Mexico and Lawrence Livermore in California) keep pursuing nuclear weapons upgrades - and now a new plutonium warhead core ("pit") factory - there is something seriously wrong.

Imaggeo on Mondays: Alas, allases are abound! | GeoLog
The Lena River flows throughout Russia from its source in the Baikal Mountains out into the Arctic Ocean, where the delta’s landscape is dominated by ice-rich Yedoma and thermokarst lakes. Thermokarst lakes have been identified as a source of carbon release to the atmosphere and Yedoma-like lake sediments are known to release more methane than any other sediment due to their incredibly high carbon content.

sanctuary: Yedoma is Here
Have you heard of Yedoma? Outside of those folks that study ice cores and worry about melting permafrost (the fragile layer of frozen soil found in arctic and some subarctic regions) on this planet, most of us would likely have no reason to know anything about it. It is, however, a subject we may want to acquire some basic knowledge about.

More Yedoma Carbon is Being Rapidly Converted to CO2 than Estimated
A team of researchers have found that carbon is being thaw released from Yedoma along the northernmost Siberian Arctic coast which stretches to around 7000 km. Increased warming of the Arctic climate may accelerate the collapse of the Yedoma leading to more CO2 being released. The Arctic region is experiencing double the climate warming which is considered as the global average.
