2018/09/22: Permafrost thawing could indeed release ancient fossil fuels in areas where they intersect.
So now, in the Arctic’s August warmth, she had come back to this isolated spot with a small research team, along with her husband and two young sons, to see what secrets Esieh Lake might yield. Was it simply a bizarre anomaly? Or was it a sign that the thawing Arctic had begun to release an ancient source of methane that could worsen climate change?
When the scientists examined samples of the gases, they found the chemical signature of a “geologic” origin. In other words, the methane venting from the lake seemed to be emerging not from the direct thawing of frozen Arctic soil, or permafrost, but rather from a reservoir of far older fossil fuels.
If that were happening all over the Arctic, Walter Anthony figured — if fossil fuels that had been buried for millennia were now being exposed to the atmosphere — the planet could be in even deeper peril.
Scientists know the permafrost contains an enormous amount of carbon — enough to catastrophically warm the planet if it were all released into the atmosphere. But they don’t know how fast it can come out and whether changes will be gradual or rapid.
the continuing growth of thermokarst lakes — many of which have already formed in the tundra — could more than double the greenhouse gas emissions coming from the Arctic’s soils by 2100. That’s despite the fact that the lakes would cover less than 6 percent of the total Arctic land surface.

Scientists are warning that rising emissions of methane in the Arctic waters could cost the world trillions of dollars.
Permafrost zones occupy nearly a quarter of the exposed land area of the Northern Hemisphere. NASA's Carbon in Arctic Reservoirs Vulnerability Experiment is probing deep into the frozen lands above the Arctic Circle in Alaska to measure emissions of the greenhouse gases carbon dioxide and methane from thawing permafrost -- signals that may hold a key to Earth's climate future.
