The greatest factor in projected sea level rise is the average temperature of the oceans--warm water takes up more volume, and there is a lot more water than ice in the world. Melting of land-supported ice is a fairly distant second.

This is not a direct response to you, but it's a fact that few people seem to realize when discussing ocean levels and global warming.

Interesting, can you cite references for this?

This is covered in the discussion of sea-level rise in the IPCC reports linked in several comments above. Wikipedia has a page about it with lots of source links:

edit to fix link

Jakobshavn Glacier drains 6.5% of the Greenland ice sheet

Right, I'm just saying that this event didn't cause an immediate increase in sea level.
