What are you basing your numbers on? From a quick look at the raw data [1], I see the high point in the 1992-95 timeframe as 13.74cm (early 1995). The high point in 2012-15 was 21.55cm (mid 2012). This is a difference of 7.81cm. The standard deviation among yearly high points is 5.62cm across all years, so this is not even close to being a significant change. If you look at the top 5 yearly high points starting with the largest, they occurred in 2007 (26.76cm), 2011 (21.79cm), 2012 (21.55cm), 2010 (18.56cm), and 2014 (18.24cm). Note the 2014 value is over 8cm less than the one in 2007.<p>Look, I get that living right at sea level isn&#x27;t exactly ideal, and these people might need help. But let&#x27;s not make more of this than there is.<p>EDIT: Also note the big difference in granularity across years. Most complete years had 36-37 measurements. 1992 only had 2 and 1995 had only 31. Thus it&#x27;s quite possible (even likely) that timeframe&#x27;s real high point was considerably higher than what is recorded.<p>[1] <a href="http:&#x2F;&#x2F;sealevel.colorado.edu&#x2F;cgi-bin&#x2F;table.cgi?q=content%2Finteractive-sea-level-time-series-wizard&amp;dlat=7&amp;dlon=171&amp;fit=n&amp;smooth=n&amp;days=60" rel="nofollow">http:&#x2F;&#x2F;sealevel.colorado.edu&#x2F;cgi-bin&#x2F;table.cgi?q=content%2Fi...</a>
