I saw that show.  Seemed to be quite factual.  Timeline for the thing
might be under a decade for it to complete.  By complete, the last
figure I saw on ocean current speeds today was about half what it was
30 years ago, with the slowdown apparently accelerating rapidly.

We humans, frankly do not have the resources to artificially restart
it.

That was what was scary.  That current has made life quite tolerable
for both our northeastern seashore states, and the whole of europe
over the last couple of centuries, and it it stops, that will all
revert to siberian conditions quickly.  Unforch, the warming is such
that the siberian permafrost is now thawing, enough to make large
amounts of the area in-accessable without air transport, which is not
economically feasable for much of it.  Sounds crazy to say the
permafrost is thawing and that some parts of the planet will get
colder, but thats how it appears to work.

Heh, and what kind of a government and environment will they have?
We've survived as a republic for 230 years now, but with the social
upheaval this is bound to cause, will our beloved republic stand?
