Great documentary in explaining the risks of large and rapid SLR, although 72 feet (23-24 meters) of SLR by 2300 and 50 feet (16-17 meters) of SLR per century from 2200 onwards as a worst-case does not seem to be based on published research.
About 10 meters of SLR by 2300 (Meehl et al 2012) and about 25 meters by 3000 (Goelzer et al) seem to be the worst-cases published so far. Which is bad enough, and doesn't have to be the last word.
