jopo's blatherings kept me busy, so I've just watched this one. I think this is consistent with the IPCC 1-2m sea level rise by the end of the century. But I think it demonstrates that our increased knowledge since the last IPCC report suggests it's more likely 2m. IPCC reports have always (as far back as they have been making that prediction) said that 1-2m was already committed because of existing warming. But they've to date said 1m was most likely and that further sea level rise would most likely take place over hundreds of years. Looks like that view may change to 2m for the end of the century for next report, but we'll see how this and further work shakes down. The idea that 1m could happen in 20-50 years is pretty dramatic, I presume we'd all agree. Adapting to 2m by the end of the century sounds vaguely manageable. But if we cop the first metre of that quite quickly, we'll be busy!
