Release of ancient methane due to changing climate kept in check by ocean waters

Ocean sediments are a massive storehouse for the potent greenhouse gas methane. But methane only acts as a greenhouse gas if and when it reaches the atmosphere. Environmental scientists recently set out to discover whether or not this ancient-sourced methane, which is released due to warming ocean waters, survives the journey from the seafloor and reaches the atmosphere. https://www.sciencedaily.com/releases/2018/01/180117164022.htm
