sea level rise is slowing, page-88

Here are a couple of estimates of inundation due to SLR:

The Environmental Protection Agency estimates that 26,000 square kilometers of land would be lost should sea level rise by 0.66 meters, while the IPCC notes that as much as 33% of coastal land and wetland habitats are likely to be lost in the next hundred years if the level of the ocean continues to rise at its present rate.

Obviously there will be many places where there will be little effect due to the slope of the coastline, and others that will have major effects (e.g. bangla desh)
