1.4 trillion metric tons of stocks of carbon in the arctic permafrost and 1.2 trillion tons of methane! Accelerated out

 

Hi Jim: The 2022 NOVA arctic sinkholes doc actually corroborated the methane stored in the arctic: 

"In the late '90s into the 2000s, people start to look at the stocks of carbon in permafrost. And it's, it's a lot, it's about 1,400 billion metric tons....Methane released by thawing permafrost has a particular chemical fingerprint. When the scientists at Esieh Lake studied the methane in the bubbles, they discovered it originated deeper inside Earth. Much deeper....Miles beneath the permafrost, deep in Earth's crust, lie huge fossil methane reservoirs. While methane from permafrost comes from organic matter thousands of years old, fossil methane comes from organisms that decomposed millions of years ago.... what you can see here is a thaw chimney going from somewhere below 150 meters to the surface, where we see the rising bubbles.... a warmer, semi-permeable passageway through which fossil methane rises to the surface. So, thawing permafrost means not one, but two sources of methane for our atmosphere."

And from this article by 

Heiner Kubny, PolarJournal: 

"Researcher Katey Walter Anthony and her team from the University of Alaska Fairbanks investigated methane emissions from taliks in the Yedoma uplands....upland taliks release significantly more methane in winter than in summer. Given that the Arctic is warming almost four times faster than the global average, this additional methane source could trigger a self-reinforcing cycle of rising temperatures and further permafrost thaw."
