AB: A number of TV documentaries, a report commissioned by the U.S. Pentagon, and last summer's movie all push the theme that were global warming to lead to a halt in the Atlantic's conveyor circulation, Europe would be plunged into another ice age. It seems to me that the only way this could happen is if the northern Atlantic were to freeze over. As models suggest that in order to shut down the conveyor global temperatures would have to rise 4 to $6\deg$C such a freeze over is highly unlikely. The context for this line of thought will be presented.
