Hi Michael,

This article on "thermohaline circulation" (from 4 years ago) does not include 
a lot of recent research. Current data does indicate the circulation may be 
slowing (although the figures have a high degree of uncertainty), but, 
contrary to expectations, seas are actually warming. 

One certainty is that the more energy (heat) contained within a "closed 
system" (such as the earth) the more violent will be the weather. I always 
think of a milk pan just below simmering on the hob (this is a fairly stable 
condition) now pop a lid on!!!

Cheers

Deri
