The surface salinity does seem to be dropping. Anybody know haw much
drop to shut down the guld stream?

About the level it reached two years ago - according to WHOI it has
already started.



"At what threshold will the Conveyor cease?
The short answer is: We do not know. Nor have scientists determined the
relative contributions of a variety of sources that may be adding fresh
water to the North Atlantic. Among the suspects are melting glaciers or
Arctic sea ice, or increased precipitation falling directly into the ocean
or entering via the great rivers that discharge into the Arctic Ocean.
Global warming may be an exacerbating factor."

This is a couple of years back. Do you have more current sources?

WHOI are a bit edgy 'tis true. I was quoting from something I read a couple
of years back too.
To be serious for a minute I would agree with your source in that the short
answer is we just dont know.
But what we do know is that it *could* happen tommorrow and that if it were
to happen it *could* happen within a single year.
Ice cores and more particularly sea-bed cores from the north west Atlantic
show us it has already happened that quickly in the past.
