I've spotted the very camera shy Nessy. Who knew that she'd been hiding in Venice!

No, the article seems to answer that quite explicitly.

Rich,
Sorry, but you are cherry-picking.  Selectively choosing the highest rate over the past decades does no one any good.  Conversely, someone could choose the last three years, when sea level rise has slowed to 1.5 mm/year, and say that the water is slowing.  Neither describes the situation accurately.

I'm happy to pick up the topic of "cherry picking" and peel back the layer on that claim.

If you look at the chart of sea level rise in the satellite era, you will sea a relatively steady rise in the graph with 3 significant downward spikes in 1998, 2011 and 2016. There are no dramatic upward "spikes."

The downward spikes are associated with El Nino's ('98 and '16) and an unusual precipitation event which transferred massive amounts of water from ocean to land ('11).

As far as I know, there is no theory which supports any exogenous processes causing short-term spikes in global sea level rise. Only the chronic processes of thermal expansion and loss of land ice are material factors in GMSL increase.

If we peer closely at the curve, we see the pause for the 2016 El Nino and the resumption of the 8mm year increase in 2017. Another pause follows and the resumption of the accelerated increase from April to October 2018.

You can jump to the assumption of "cherry picking", but I'll challenge you to offer a cogent theory as to what might be causing a short-term increase in the slope of the curve that wouldn't be sustained.

The signal is there that SLR is accelerating and it's corroborated by all of the reports that Greenland and Antarctica are losing ice at accelerating rates. Will their continue to be periodic downward adjustments for events like El Nino's and other anomalies like the 2011 precipitation event? Absolutely!

What I'm saying is that we've entered a new normal for the chronic processes of thermal expansion and land ice loss which will only increase in pace in the coming decades.
