[This link][1] is a scientific talk by geoscientist [Jerry Mitrovica][2] ([Harvard University][3]) called 'Sea Level Fingerprints of Ice Sheet Collapse'. It's about an hour long, fairly technical, and focused on ice sheet contributions to sea level change (it was for an audience of other scientists), and has some good background related to this question. I highly recommend watching if you have the time.
