Oooh look, a hockey stick
Considering that the sea level has changed by a few inches over the last 160 years, for it to suddenly change by up to a foot in 20 years is just bonkers. Even if you take into account an earthquake, one so big that it'll have to be bigger than the one at Fukishama 'cause none of the past earthquakes have made any significant change in sea levels, it's still bonkers.
