Update: "Sea level rise is not accelerating". Well, common sense tells you that it is, since it's actually happening to the extent that coastal cities around the world, as my link says, really and truly do have to do something about it.

Also, to quote from ioerr's first link: "Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satellite data."
Update 2: Also, NOAA says it is increasing too. From Ioerr's second link:
"Is sea level rising?
Yes, sea level is rising at an increasing rate."
