“Methane Emissions Continue to Rise”

Val Eisman

“"“The degradation of underwater permafrost on the Arctic shelf may result in large amounts of greenhouse gasses, predominantly methane, escaping into the atmosphere,” he added. “It is unknown precisely how many methane reserves exist in subsea permafrost and sub-permafrost horizons on the Arctic shelf. Still, current estimates suggest that there can be up to a trillion tons of methane on the East Siberian shelf alone.”

For comparison, an [estimated 570 million tons of methane],…

…are released into the atmosphere globally each year, a number that is dwarfed by the reserves locked up in the ESAS. Scientists are concerned both by the gargantuan volume of gas reserves and the shallow depth of the ocean over much of the shelf, which makes it easier for greenhouse gasses to bubble up to the surface and into the atmosphere, compared to deeper waters that can absorb these emissions.'
