Widespread methane leakage … from the sea floor on the northern US Atlantic margin.
“In an area between North Carolina and Massachusetts, they have now found at least 570 seeps at varying depths between 50m and 1,700m. […] The scientists say there could be about 30,000 of these hidden methane vents worldwide.
“The methane is dissolving into the ocean at depths of hundreds of metres and being oxidised to CO2,” said [Prof Adam Skarke from Mississippi State University, who led the study].

“Contemporary upper-slope seepage there may be triggered by ongoing warming of intermediate waters, but authigenic carbonates observed imply that emissions have continued for more than 1,000 years at some seeps.”
Translation: We’d love to blame global warming … but since it has been going on for 1,000 years … we can’t … unless you are dumb.
