Presumably any increase in temperature will result in some clathrate
decomposition ?

Although there is the potential for released methane to contribute to a
runaway effect, it's not a simple "hydrates will be released" or not
thing is it ?


Don't know :-(

And I am not sure anyone else does.


I'm pretty sure that physical chemists can tell you about the
thermodynamics of clathrate formation, and if they can tell you, it can
be modelled.


No, the idea of methane clathrate is still pretty new, and exactly how
they behave is not well known.

Moreover, their release is probably dependent on pressure and temperature.
That means that one needs to know not only how fast global temperature
will rise, and how that will affect sea temperatures at the depths of
clathrates, but we also need to how fast sea levels will rise in order to
know the pressures at the depths of clathrates.

It is not the sort of thing you want to
talk about. You could be labelled as a crackpot!


Don't see why...


When you predict that the end of the world (as we know it) is coming
then you are labelled as a crackpot (or a Chicken Little)-!
