DoomsdaysCWSea of #methane sealed beneath #Arctic #permafrost could trigger climate feedback loop if it escapes
A sea of migrating methane discovered below the permafrost in Svalbard may eventually escape its icy prison if the permafrost continues to thaw due to #ClimateChange.

"Deep beneath the permafrost that blankets a group of islands in the #ArcticOcean lurks a growing and migrating sea of methane, researchers have discovered.
"The thick permafrost, or ground that remains frozen for at least two years, forms a tight seal that has so far prevented millions of cubic feet of methane from wafting out — but there's no guarantee that the potent greenhouse gas won't eventually escape, according to a study published Dec. 13 in the journal Frontiers in Earth Science.
"At present, the leakage from below permafrost is very low, but factors such as glacial retreat and permafrost thawing may 'lift the lid' on this in the future," lead author Thomas Birchall, a geologist at the University Center in Svalbard in Norway, said in a statement."
