Sea levels to continue to rise for 500 years? Long-term climate calculations suggest so

ScienceDaily (Oct. 17, 2011) — Rising sea levels in the coming centuries is perhaps one of the most catastrophic consequences of rising temperatures. Massive economic costs, social consequences and forced migrations could result from global warming. But how frightening of times are we facing? Researchers from the Niels Bohr Institute are part of a team that has calculated the long-term outlook for rising sea levels in relation to the emission of greenhouse gases and pollution of the atmosphere using climate models.
...
In the pessimistic scenario, emissions continue to increase. This will mean that sea levels will rise 1.1 meters by the year 2100 and will have risen 5.5 meters by the year 2500.
...
For the two more realistic scenarios, calculated based on the emissions and pollution stabilizing, the results show that there will be a sea level rise of about 75 cm by the year 2100 and that by the year 2500 the sea will have risen by 2 meters.
...
 it would be 2-400 years before we returned to the 20th century level of a 2 mm rise per year,

OK, so its another 'official' view that sea levels will continue to rise for a long time, and even if things 'stabilise' at the 20th century rate of 2 mm per year, its going to keep on keeping on.

ScienceDaily (2011-07-18) -- Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, scientists have found. The results further suggest that ocean levels continue to rise long after warming of the atmosphere levels off.

    'The maps here show the world as it is now, with only one difference: All the ice on land has melted and drained into the sea, raising it 216 feet and creating new shorelines for our continents and inland seas.

    There are more than five million cubic miles of ice on Earth, and some scientists say it would take more than 5,000 years to melt it all. If we continue adding carbon to the atmosphere, we’ll very likely create an ice-free planet, with an average temperature of perhaps 80 degrees Fahrenheit instead of the current 58.'
