Gonna try reading thru the linked paper tonight.

I’m absolutely no expert but surely the seasonal variation in sea ice shows that its extent and volume can change very rapidly so that a small decline in global temperatures would lead to a fall in sea levels invalidating the statement that:
“Due to the long time it takes for the world’s ice and water masses to react to global warming, our emissions today determine sea levels for centuries to come.”
I think I trust Mark Twain more:
“In the space of one hundred and seventy-six years the Lower Mississippi has shortened itself two hundred and forty-two miles. That is an average of a trifle over one mile and a third per year. Therefore, any calm person, who is not blind or idiotic, can see that in the Old Oolitic Silurian Period, just a million years ago next November, the Lower Mississippi River was upwards of one million three hundred thousand miles long, and stuck out over the Gulf of Mexico like a fishing-rod. And by the same token any person can see that seven hundred and forty-two years from now the Lower Mississippi will be only a mile and three-quarters long, and Cairo and New Orleans will have joined their streets together, and be plodding comfortably along under a single mayor and a mutual board of aldermen. There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.
- Life on the Mississippi”

A few months ago I wrote Part 1 of ‘Historic variations in sea levels-from the Holocene to the Romans.’ It is here
A much more comprehensive version is here.

It is clear that there are considerable variations in levels which may coincide roughly with warm/cool periods. We are currently around 20cm or more BELOW the levels that occurred during the Roman optimum. There are a couple of useful graphs in the article towards the end that show this. As our current temperatures are somewhat below that period it seems unlikely we will reach it (unless temperatures continue to rise strongly) although there is the considerable wild card of the pumping of water from underground sources which may affect levels in a manner that hasn’t happened in previous sea level changes

“The press releases from organisations wedded to the AGW gravy train become more sensational over time. The money must be good, because they seem to have no idea how ridiculous they appear to thinking members of the community.”
Yes the money in CAGW “science” is VERY good right now…even the WUWT trolls don’t argue with that.
My climate “projection” for 2012? Expect to see a rapid increase in the frequency and hysterical tone of climate “science” press releases (like this one) as we approach the U.S. elections in November.
Did it ever occur to those involved in the study that the east coast land mass just might be sinking a bit. Like is being shown to be the case on parts of the Louisiana coastline.
I wouldn’t want to have to play “moving chairs” with these folks. Surely I would loose big time. :)
Global Warming on Free Republic
I'll bet there's a place - maybe close by - where the water is dropping 3 times faster than normal - and that it's NOT being reported.

I’ll ask again, where is that dangerous SLR coming from? Check out the graphs of “all the models” for Greenland positive and Antarctica negative for the next 300 years.
http://rsta.royalsocietypublishing.org/content/364/1844/1709/F4.expansion.html
We’ve covered 99% of the planet’s ice and 89% ( antarctica) will be gaining ice until the year 2300.
So where’s that SLR to come from again?
