Ice Age Floods cause mass extinctions?

It is mostly a function of the oceans currents. The heat in southern hemisphere is carried north by the currents. There was a good article in nature (unavailable now unless your a member )

from the your link

The cores suggest that the climate shifts were local, not global like we are seeing today.

It is my contention that what you say remains true today. What I didn't think about was that any regional climate will have an effect globally since we're all on the same planet. Synergistically speaking if it warms up in Artic waters, something's going to change on another part of the planet.

What I find equally interesting is your mention of fresh water changing the course of ocean currents. Is there any physics, fluid mechanics or oceanographic evidence that shows how de-salinated water can shift a salinated current?

Here's something that might help out.
