I applied a polynomial trend line to the data: seems there is a 7.5cm rise over 23 years, but most of that was in the first half and has tapered off and may actually be about to head down. I'd like to see longer-term data. Recurring issue: climate changes. Sea levels change. Land altitudes change. Overlapping cycles interact to great effect covering hours & millennia. And when you're talking about all of these happening in regards to someplace that is no more than 2 meters above "sea level", with nearly a meter of tidal variation daily, it's not unreasonable to conclude "living on the edge of survivability isn't a good choice".
