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&#x27;d like to see longer-term data.<p>Recurring issue: climate changes. Sea levels change. Land altitudes change. Overlapping cycles interact to great effect covering hours &amp; millennia. And when you&#x27;re talking about all of these happening in regards to someplace that is no more than 2 meters above &quot;sea level&quot;, with nearly a meter of tidal variation <i>daily</i>, it&#x27;s not unreasonable to conclude &quot;living on the edge of survivability isn&#x27;t a good choice&quot;.
