According to a new study, water at intermediate depths of the Pacific Ocean has been warming at a rate that can melt the carbon deposits and release harmful methane into surrounding water. It was found by researchers that water off the coast of Washington is slowly warming at a depth of 500 meters, about a third of a mile down. That is the same depth where methane changes from a solid to a gas.
The research suggests that there is possibility that ocean warming could cause the release of a powerful greenhouse gas. Methane is a greenhouse gas, various times more powerful than carbon dioxide in warming the planet.
