Yes. 'The Big Chill', on Horizon. There's a lot of talk about it on the user
board at www.climateprediction.net where there's a lot of us running
simulations on our home PCs to see how likely it really is. It'll be a long
time before the results are through but one suggestion is that the sink zone
where the gulf stream sinks again wouldn't have to actually stop. If it just
drifts south a bit then it'll get a lot colder here without a resultant
ice-age.

Perhaps even colder than it it does stop! Arctic water flowing south
is worse than the lack of tropical water flowing north.

Does anyone know what happened to it in the period 20,000-10,000 B.P.?
Did it start up or simply move north?
