We can compare current salinity with that at past times by taking core samples. And at those same points in time we can determine, with some degree of accuracy, the climate.

Some assumptions must be made.

And with time they will be modified and become increasingly more accurate.

What Europe is worried about is the mid-Atlantic conveyor stopping. If it does Europe, as we know it ends for the rest of the lifetimes of all alive. Not a happy thought.

We know how to stop it. We don't have a clue how to restart it.
