From: "Rich Gauszka" 

Land Methane ( Siberian bog ) is being rapidly released now. It won't take
much ocean warming to release the vast amounts of frozen methane. 55% of
ocean species died off the last time that happened.  There will be vast
climate change.

 Sure throwing a super volcano into the mix is just a hypothetical doomsday
scenario but whether it's the Siberian Trap, Yellowstone ,  Phlegrean
Fields volcano West of Naples, Italy,  Lake Taupo in New Zealand amongst
others, one of these suckers is eventually going to erupt and I'd rather
not have it happen when methane is being rapidly released from the ocean.
