Must Watch
Published on Mar 6, 2013
Methane extinction is a very real
phenomena... unfortunately. The clathrate gun hypothesis is the popular
name given to the hypothesis that rises in sea temperatures (and/or
falls in sea level) can trigger the sudden release of methane from
methane clathrate compounds buried in seabeds and permafrost which,
because the methane itself is a powerful greenhouse gas, leads to
further temperature rise and further methane clathrate destabilization
-- in effect initiating a runaway process as irreversible, once started,
as the firing of a gun. The best example (or worst) is the Permian
extinction event, when 96% of all marine species became extinct 251
million years ago.
