Climate Change

Wouldn't igniting the shit be the smart thing to do?

A system like that should have cutoff valves specifically for stopping gas escape if the piping gets breached.  I don't understand why these valves haven't been closed already, even if it takes saturation divers to go down and close them.  Or have the well heads themselves been blown up?

No, there are no shutoff valves along the length of the thing because of access problems if they were to malfunction. Those lines are always full of gas, liquefied gas for negative buoyancy, you don't want the things floating to the surface which they could do if empty.
100,000 tons of liquid gas will take months to boil off.
