In "Mother of Storms" by John Barnes a superstorm is postulated. 
Methane....that arch green house gas....is the villian.
I quote:
"One strange fact about ice, when you think about it, is that it floats.  
Solid butter sinks to the bottom of liquid butter, solid iron sinks to the 
bottom of liquid iron, solid nitrogen sinks to the bottom of liquid 
nitrogen...but solid water floats on liquid water.
Imagine a microscope fine enough to show you why.  The water molecule is bent 
at an agle and try as you like, it doesn't pack neatly.  Freeze water, so 
that the molecules start to lline up into crystals, and that sloppy packing 
leaves a lot of empty space,--more empty space than when they are just 
rolling around on each other.
Freeze water another way, and there's so much extra space you can trap other 
molecules between the water molecules.  That's called a clathrate--Latin for 
a "cage, trellis, or grating"---and all kinds of things can be held in there.
As when twenty-three water molecules make a cage around four methane 
molecules.
There is lots of methane in the seabed.  Everything that sinks down there 
rots and there's not much free oxygen. Many anaerobic decay processes release 
methane.  Dead stuff has been rotting on the seabed for a long time--and 
since the last few ice ages, it's been cold enough down there to trap methane 
in the clathrates.  On the Artic Ocean floor  many clathrate beds are tens of 
meters thick and hundreds of kilometers across"
End of quote.
Presumeably methane clathrate doesn't float.
I dunno if the above is true or not...(I have no internet connection any 
longer....just email...so I can't check it out)  .it certainly sounds 
feasible to me.
If it IS correct...and if a huge amount of methane is suddenly released into 
the atmosphere.....then presumeably there would  REALLY be some global 
warming.
And  oceanic warming .
If the oceans get warmer the Hurricane spawning grounds get larger.  If the 
spawning grounds get larger the Hurricanes get larger.  Possibly a LOT larger.
If there is ENOUGH methane released into the atmosphere.....and the ocean 
water temp gets to ......say........a hundred degrees F. or more  over a huge 
area.........bad things could happen.
Is a hurricane with a supersonic eye wall possible?
IF it's possible what might it's effects be.
HUGE waves I would imagine.....HUGE storm surges.....
Globally.  Any location even near a sea coast would be scoured.  
John Barnes goes into such a scenario in his book which is set in the not so 
distant future.(circa 2030).......It's very interesting...I highly recommend 
it.
However.
I'm wondering what might have happened had there been,  say, an asteroid or 
small comet strike, which caused the clathate beds to release  gigantic 
quantities of methane into earth's atmosphere in pre-historic or very early 
historic times.
Suppose this is a recurring theme? Suppose it has happened every few hundred 
millenia or so.   Would such a superstorm be sufficient to cause massive 
extinctions?  Surely it would be enough to destroy primitive civilizations.
