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."

From: http://www.whoi.edu/institutes/occi/viewArticle.do?id=9986

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.

Do you think that a reduction in the Gulf Stream could result in a
reversal of the glacier melt and that this could in fact be a
self-correcting mechanism balancing warming due to increased solar
activity? Do you think that it's possible that all but 1/100th of a
degree of the warming seen in the last 140 years is due to increased
solar activity? do you think we should disrupt the global economy to
the degree required by Kyoto to have a hypothetical effect on that
1/110th of a degree? I agree there is cause for concern about climate
change, but could we do just a bit more research before we resort to
draconian measures which do little but transfer wealth?


You started with 1/100th and ended with 1/110th is the actual 1C degree of actual increase over the last 100 years diminishing as you post?



:-) Typo. In actuality, .01 degree would probably be a most generous estimate of the anthropogenic portion of global warming.


Do you have a cite for this?

BTW, it was 1F not 1C. According to the US NAS you are .99 degrees off.

"According to the National Academy of Sciences, the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most of the warming over the last 50 years is attributable to human activities. "
