Archimedes
@Andy Poulton
Sorry, but you applied Archimedes' principle incorrectly. A mass will displace it's own *volume* if *immersed*, yes, this is obvious. But a *floating* body will displace it's own *weight*, not volume. And ice floats. So, as Ken Hagan correctly pointed out above, if all the ice in the Arctic melts then this *on its own* would have no effect on sea level. Don't believe it? Fill a glass to the very brim with ice and water, then leave it, covered, until the ice has melted. There will be no spillage over the brim, nor any empty space at the top. The glass will stay full - provided it is covered to prevent evaporation, that is.
Still, as Mr Hagan rightly points out, other bad things happen when the ice goes away which do lead to sea level rising.
