Guardian article on Arctic methane emissions claiming “a new climate feedback loop may have been triggered” lacks important context

“This article’s claim that methane deposits in the Arctic Ocean are starting to be released, awakening a “sleeping giant”, cannot be supported by the limited observational data. Besides, even if these newly found seeps are increasing, they are located too deep in the ocean to have a significant impact on the concentration of methane in the atmosphere.”
