    were already as high a projected, almost all of Florida would be underwater,  the year 2000 election debacle would not have occurred, and Al Gore would have been president (and maybe even done a little bit to ameliorate the situation . .  .)

      Who projected that? Sea level rise lags surface warming.

      look for my eSci diary series Thursday evening.

      •  The diary - in the block quote - mentioned (0+ / 0-)

        a 120 foot rise in sea levels.

        It's not * that * difficult to look up the implications to Florida - for example go to Google Images and look up Florida elevation topographical map - a good 60 to 70% of the state will be under water, most of the rest will be scattered islands.

        •  Well, yes and no (0+ / 0-)

          It's not inaccurate to state that sea levels are at risk of rising that much given where we're heading. But a total melt out of Greenland or the West Antarctic Ice Sheet is not (by consensus scientists) expected for a few hundred years. Sea levels (on average) are rising about 3.2 mm a year, and of course varying oceanographic features skew who gets the brunt of sea level rise (the Atlantic side of the United States could get it pretty bad, and we're seeing that in places like North Carolina), but it's going to take a monumental increase in melt to wipe out Greenland and the WAIS to put us at 120 feet sea level rise in the next generation or two.

        •  And another important point (0+ / 0-)

          Current sea level rise has been attributed almost entirely to thermal expansion, not ice melt, which is expected since ocean heating has exploded for decades now. Warmer water expands. But, we'll see how these feedbacks shake out in due time!
