Uh...the polar ice cap was touching North Carolina 3k years ago? So 1k BC, you are saying that the Ice cap stretched down that far, that means that Europe as well would be coverd in ice.

Its not just a simple warming. Once the ice cap melts, and the desalinization of the oceans will cause massive massive weather changes. The current of the Atlantic ocean, and other oceans, will stop and weather will be pretty much be anyone's guess as to what will happen next.
Right now, we can predict hurricanes because of these currents. We know hurricanes start off teh coast of Africa, ride across the Atlantic, up through the Carrebian, and into the Gulf or east coast.
This wont be the case.
Lets not forget that what might hapen when all the carbon dioxide that is trapped on the ocean floor will come up, adding to the already **** storm...pun intended...

That is what we will happen either way, so just get ready for it.
