Another point worthy of consideration is a bye-product of a POSSIBLE shut
down or diversion of the North Atlantic gyre which brings the N. Atlantic
Drift to our shores. Centrifugal and vortical forces cause the sea surface
to be slightly dish shaped around a cyclonic gyre, dome shaped over its
counter circulation; stop them and you get changes. Whether this is a "good
thing" depends on where you are and which gyres stop/move!
