Thanks for the link, very good lecture with several fascinating graphs.
I especiall liked what he talked about the relation between temperature change and sea level, where on the long term a one degree C change translates into 20 meters of sea level change.
The total amplitude for sea level change is about 200 meter, and the total amplitude for average earth temperature is about 10 degrees C, that's how he gets the 20 meters per one degree C.
This of course is the long term steady state, and it basically means that we have already locked in our first 20 meters of sea level rise, given that earth av. temperature has risen about 1 C. He claims that about 14 meters of marine-based ice is 'meta-stable' in W.Antarctica.
He start to talk about this at around 1.02
At 1.18 he comes into the speed of SLR, and says that what we're currently seeing, is rather small in comparison to SLR that was e.g. around 15 ka ago
