One-to-one coupling of glacial climate variability in Greenland and Antarctica

[Skyhunter]

Here is the abstract.

And here is a related article.

As the Antarctic warms, the ocean currents that carry water away from the continent become stronger. Warm water flows as a surface current to the Arctic. Stronger currents transfer more heat to the North Pole, and cool the South. Cold water flows back southward along the ocean floor.

As the Arctic warms, its ice begins to melt. This adds fresh water to the sea, which disrupts the current, because it is less dense than salt water and therefore means that the diluted cold water sinks less readily.

With the current weakened, the Antarctic retains more of the Sun's heat. This warms the southern oceans, eventually causing the there ice to retreat and allowing water to enter the Atlantic from other oceans, thus strengthening the current again and completing the cycle.

With the arctic ice melting, should we expect a weakening of the warm northerly flow?

Since we are in the midst of a giant atmospheric experiment, with the only currently habitable planet that we have, I wonder how much understanding the past shifts will help in our understanding of the current climate shift?

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

I said:

More substantiation for that statement is whenever I confront real specialists with that, unlike on other occasions only deep silence follows. There has not been an attempt yet to challenge the refutal.

Just happens that an excellent demonstation of that is ongoing http://www.ukweatherworld.co.uk/forum/forums/thread-view.asp?tid=6458&start=1 , so far.

So I thought I was quoting myself in a new message, but I actually edited the message and destroyed a few minutes work that way.

However if you follow that previous link to http://www.ukweatherworld.co.uk/forum/forums/thread-view.asp?tid=6458&start=1 , the contents of that message was about the same, albeit that here in PF, I toyed a bit with Poppers philosophy about one single fact can falsify a theory, while none can prove it.
