re: #41 The Ghost of a Flea
That is really not good, if the clathrate gun hypothesis is at all valid. To the point that some sort of direct action—burning off those methane fountains?—might be a good idea.
These are all subsurface seeps. The chance that you could get to the LEL of methane at the surface or keep it lit in sea movement and wind is highly unlikely. Nice idea, though.
