Care to put a time frame on that?

Future sea level rise
In 2001, IPCC’s The Third Assessment Report IPCC predicted that by 2100, global warming will lead to a sea level rise of 9 to 88 cm. At that time no significant acceleration in the rate of sea level rise during the 20th century had been detected.[10] Subsequently, Church and White found acceleration of 0.013 ± 0.006 mm/yr².[8]
These sea level rises could lead to difficulties for shore-based communities: for example, many major cities such as London and New Orleans already need storm-surge defenses, and would need more if sea level rose, though they also face issues such as sinking land.[11]
Future sea level rise, like the recent rise, is not expected to be globally uniform (details below). Some regions show a sea level rise substantially more than the global average (in many cases of more than twice the average), and others a sea level fall.[12] However, models disagree as to the likely pattern of sea level change.[13]
