“1 millimeter = 4 inches”

1 millipeter=0.0393701 inches

“Peter, I'll take “A metric unit for shrinkage rate for $500.00”

That corrected, YES!
The actual measured global average sea level rise remains near-steady since bedrock gages were first calibrated back in the early 1920’s. For 100 years Sea Level Rise has remained steady at 2.3 to 2.5 mm per year. 1 inch in 10 years. 10 inches per century. 1 meter in 400 years.

The rest is all extrapolated hype and exaggerations!

BUT! Local area do rise and fall as the continental masses rise and lower, and - most important - as local governments permit water to be pumped out from local aquifers under their cities. New Jersey, Virginia's Norfolk area, the MD peninsula are going down now because of this.

Manhattan is on the edge of a very large continental mass that is tilting DOWN in the south because the same granite
is RISING up around Hudson Bay. When the glaciers receded from Manhattan and southern NY 12,000 - 15,000 years ago, that trillions of tons of ice let the southern continental rock rise. Now, with the glacier mass over Hudson Bay having melted out 5,000 - 8,000 years ago, that northern region is rising very quickly - and tilting the southern edge back down. (Like the old see-saws they've now outlawed for children to play on.)

Anyway - The southern tip of Manhattan Island has a slightly faster local sea level rise than the global average at 3.1 mm/year. 1.2 inches per decade, 12 inches per century.

Now, what you don't see is that these “researchers” DID NOT TELL US THAT. Either they are too incompetent to know their own state's geology and its glacier changes. Or they do not want you to know.
