Heh, yes, Orac's lower estimate is kind of meaningless without further explanation. The fact that the sea level hasn't risen by that amount proves it can rise less, so any lower bound greater than zero is immediately proved wrong.

Unless it's a lower bound _if_ all the polar ice melts. But even then, what if it does go to the moon? Or evaporate. I guess the more global warming we have, the more sea water will be retained in the atmosphere.
