Sea Level rising faster than UN report predicted

The link is to the actual open-access scientfic acticle for sea level rise.

I saw it as a news story, looked at the mostly humorous posts making fun of deniers and flat earthers, and there was a link there.

I only skimmed the article. I recall, but could be wrong, that the 2007 IPCC predictions did not include melting ice.

I'm going to send this to family co-owners of a summer house on "the island", which is high on a rocky coast (probably 20 m elevation). The bedrock of this island has been subsiding at 1.5 mm/yr for the last century (related to collapse of a glacial time (20,000 BP) bulge related to the load of thick ice to the north. With the global sea level rise having been also 1.5 mm/yr the l;ast century, I can actually visually see the relative sea level rise since I was a kid (half century). Figure 2 in the linked article shows global sea level rise of about 6 cm between 1990 and 2010, or 3 mm/yr, double the previous rate. I've heard previously that part of the increase is a big increase in melting of Greenland ice sheet in the last decade.
Note the sea level rise predictions in Figure 3: the upper curves are between 6 and 10 mm/yr. OK, that is 6 to 10 cm/decade, or up to 4 inches/decade. If it went to 8 1/2 mm/yr, plus Rhode Island's sinking at 1.5 mm/yr, that would be 20 inches in 50 years, or about 4 times what I can see visually on the coast since I was a kid.
