I wanted to acknowledge your reply, because you took the posting

future weather behaviour given various assumptions.
Or as you took it, the underlying ocean current patterns.

Do you have a reference, btw, for "There is paleoclimatological
evidence that ocean circulation was reversed in warmer periods."?

I confess to not being up to date on this issue. Latest papers seem to mostly
support the idea that tropical water will not be dense enough to form bottom
water, but will remain at intermediate depth. However, this is somewhat of
a subtle difference as the bottom water still did to warm to 15C to 19C,
rather than to 25C. I do notice that one model does exhibit oscillating
response to one set of conditions. However, the period was about a thousand
years.

I also looked other papers. See:
