The problem is, if you read the glaciologists studies, there is a limit to how fast the ice sheets can actually melt. The "Complete" collapse of Greenland is, in a few centuries, unlikely, as it did persist through the previous interglacials.
The YD occurred due to the sudden release of an impounded glacial lake (Lake Agassiz) that probably drained at least a portion of the water through the great lakes into the St Lawrence and out into the Atlantic, slowing down the circulation in the North Atlantic
The major difference, is that, while some studies show the steady increase of Freshwater may have the same impact, others show that you really need a sudden release of Freshwater to have the impact in the N. Atlantic. The slow steady guys argue for a "Tipping Point"
While anything is possible, a more realistic scenario is probably preparing for 1-2m of sea level rise by the early 22nd century, which will have pretty drastic impacts on a lot of major cities and infrastructure in the US and around the world. Not to mention, the impacts of warming on drought, crops etc... The accelerating SL rise alone is enough to prepare for without so called "Global Warming"
but then again, this is all BS. What do I know, I spend my time reading the scientific literature, not someones hacked emails or Al Gore's books... (I'd have to look up references if you want specifics, they are sitting in folders of PDF's on my hard drive) the rest above is from my internal RAM
