RE Archimedes' law -- correctly; by gabor
Gavin Schmidt over at Real Climate (google scholar -"Results 1 - 10 of about 107 for "Gavin Schmidt" climate change.") did the calculations and came up with 0.3 mm sea level rise.
(FYI; google scholar -"Results 1 - 1 of 1 for "Brian Dodge" climate change." Not me; different Brian Dodge. If you don't trust 0.3mm is accurate, do your own research/calculations.)
