Besides, I've been meaning to share this video since first watching it last year. Here is some very interesting and relatively new scientific understanding regarding sea levels and the changes we might come to expect.
Dr. Mitrovica does a wonderful job of explaining the interactions between melting ice sheets; gravity; and surface rebound which have enabled scientists to better estimate regional sea level rise for various geophysical scenarios.

This meeting was held March 31-April 2, 2011 at the AAAS Auditorium, in Washington, D.C.
Climate science is addressing issues that require an increasingly interdisciplinary perspective, posing new challenges to scientists and to the organization and support of this science. Like other interdisciplinary activities, recognition and support of interdisciplinary climate science by the broader scientific community—including university and government administrators, journal editors and reviewers, and funding agencies—is advancing slowly.
Often it is easier to recognize ideas that would represent major advances within a discipline, than ideas that would provide major advances but cut across multiple disciplinary foundations. This circumstance poses a challenge to interdisciplinary research and may slow interdisciplinary scientific advances. Such issues are of particular significance for studies of climate impacts, which may, for example,represent linkages between physical and social science, as well as feedbacks among physical, chemical and biological systems.
This Sackler Colloquium will provide a forum for addressing these issues. Specifically: How are high-quality interdisciplinary scientific ideas best recognized and nurtured in their nascent phase? How can we improve this recognition process so as to better support interdisciplinary climate science advances? The colloquium will examine the history of successful, innovative interdisciplinary scientific advances, drawing on experience not only in climate science but also in other fields.
The purpose of the colloquium is to identify patterns in the evolutions of research in these areas. Are there common characteristics and/or principles that allowed critical efforts to succeed, thereby leading to significant advances? Did they begin as small concepts or as big, break-out ideas? How were these efforts nurtured, supported, or hindered? At what career stages were the primary researchers? How might future, novel interdisciplinary ideas in climate science be better identified?
2mm/yr is not anomalous - sea level has been rising at this rate for thousands of years.
Sea level change varies dramatically from place to place - melting ice sheets cannot be the culprit.
Regardless, 2mm/yr is small and stable ... it won't change.
Mass of Ice Sheets exert a gravitational force on the water. Resulting in counter-intuitive sea-level changes...
Adding water; relaxing the gravitational tug...
"Probabilistic assessment of sea level during the last interglacial stage"
IN THE POPULAR imagination, sea levels rise in response to a warming climate in the same way water rises in a bathtub when the tap is turned on: evenly and uniformly around the globe.
Until nine years ago, many scientists also assumed the same thing. That’s when professor of geophysics Jerry X. Mitrovica (then at the University of Toronto) and collaborators including Harvard College Observatory associate James L. Davis reported in Nature that incorporating glaciers’ gravitational pull into the equations used to describe sea-level changes would help explain the extreme variation scientists were already seeing around the world.
The equations then in wide use accurately described the trend in average sea level worldwide—a rise of about two millimeters per year in the twentieth century—but couldn’t explain why actual observed conditions in many places did not conform to that average. . . link
In response to Dave Burton's comments and seeing that he's a champion for Nils-Axel Morner one of the most well known sea level rise contrarian scientists who claims the world's scientists are in on a conspiracy and that sea level rise is nothing for us to worry about, or think about for that matter.
So who is Nils-Axel Mörner, and how is he able to see these things that every other scientist in the world can’t?Well, in addition to his activities “debunking” climate change, Mörner is also an enthusiast of dowsing and water witching.And he has some very weird ideas about archaeology. See here, here, here, and here.And he is associated with fringe wacko/antisemite/conspiracy theorist Lyndon LaRouche. Here’s an interview (PDF) he did with the LaRouche publication Executive Intelligence Review.And he is an “allied expert” with the Natural Resources Stewardship Project, a group that is controlled by energy industry lobbyists.
