The last i heard scientist's were planning on trying to bury Greenhouse gasses? but if they are now naturally coming to the surface will this idea even work? secondly there are suposedly huge amounts of this stuff naturally on our ocean floors iirc so just how catastrophic would it be if this was suddenly dumped into the atmosphere?
