The ice sheet will have to have a volume corresponding to the increase in sea level, ie whatever volume of water you'd have over 16 feet applied
across the world coastlines.
This sort of thing has certainly happened before, or at least enourmous peices of ice have slowly plopped into the artic oceans before. Its thought
that, if into the atlantic, it'd desalinate the water, thus shutting down the M
urrent, a density driven transoceanic
cycling of water. I don't know if that specifically alters weather globally, but it does seem to be associated with Ice Ages.
Threat? Absolutely, positively, and completely and entirely plausible.
But is it actually occuring? Thats vitally important. Everyone has to be certain that its happening before they start evacuating coastal areas below
"6 feet above sea level"

The report you cite states it may be. How long have they been recording melt data or whatever for that sheet?
they have found ice to be flowing into the sea at the enormous rate of 250 cubic kilometres a year.
And what is this relative to it former melt rate? And to other ice sheets in the region?
it would probably cause devestating tsunamis worldwide at the time of collapse, no?
I'd think no, not actual tsunamis anyway, but it'd be a rush of water I'd think.
I would like to know which countries and land masses are at 16 feet sea level.
Hell, most. A 16 foot rise in sea level would pretty drastically change the coastlines of the world. Lots of micronesian/polynesian/indonesian
countrys are only a few feet above sea level to begin with.
