“Sea levels have continued over the last 20 years to rise at a rate of approximately 3 mm/year”
It boggles my mind that we can measure 3 mm per year ....
more boggling is the hurricane that at level 5 hits Miami dead on and destroys a $110 trillion of on the waterfront at sea level property.
Watch the glorious color intro to CSI Miami and think category 4 or 5 hurricane
One would have to have a very good tidal gauge to measure 3 mm. Nothing else could discern that small a change. What I have read is the real SLR is maybe 2mm at most and likely stopped about 10 years ago. The rise was primarily due to thermal expansion as the oceans warmed after a cold Little Ice Age.

It does seemd difficult but I would think that it could be measured over the course of years and averaged out it it were indeed true. What I find far more laughable is the claim to measure the average temperature of the entire Earth over the span of a year or many years to an accuracy of 1/100th of one degree.
