Sealevel rise is a consequence of global warming.  Has been in the geologic past and is expected to be in the future.  Most of the numbers you see refer to estimates of the rise by the year 2100 and some estimates aren't too alarming.  Some recent geologic work has shown that there has been at least one fast rise:  "confident that the 17-foot jump happened in less than a thousand years — how much less, he cannot be sure."  (at http://www.nytimes.c...level.html?_r=2& )  See also : http://www.realclima...sea-level-rise/    Less than a thousand years, but how much less?  Can't tell.  Could be a little less.  Could be way less.  "babies being born now could live to see the early stages of a global calamity."

Even without a substantial rise in the levels, we are already seeing the effects.
Several island nations are either under water or will be in just a few years-completely gone.

With just minute rises, we will see damage along the coasts from flooding when it's coupled with
storm surge.

They keep talking "centuries"-imo, more like decades or less.

NOAA says .5 meter or about 20" max by 2100.  17'/1000 years= 1.7'/century, about the same as NOAA's worst case.

A recent survey of the experts show a range of
low end- (if emissions are drastically cut) of 1.3-2 feet
high end- 2.2-4 feet.
With this caveat-
"Most experts on this topic think there's no way to avoid at least some sea-level rise.
Based on the paper above, even cutting cumulative emissions more than 70 percent will still lead to
sea-level rise of 0.4 to 0.6 meters (1.3 to 2 feet) by 2100.
The main choice here may be between "some" and "a lot." "
