NOAA has launched a new sea level website
In New York, under the Intermediate Scenario, sea level is expected to rise 11 inches from 2020 to 2050.”
National Sea Level Explorer – U.S. Sea Level Change
Three years ago NOAA’s sea level scenarios were failing badly, so they moved to goalposts out twenty years and made some new baseless predictions.
Apparent sea level rise rates at Manhattan are less than 3mm/year, all of which is due to subsidence. At that rate sea level will rise 3.5 inches by 2050.

I presume NOAA knows that the sea in New York is the same sea in London Monaco and Venice, the same water connects those places, and you can sail easily between those places.
I’m not a NOAA scientust, but if I was I might be inclined to predict the same amount of rise in Monaco and Venuce, as New York, because if you dont do that you need to explain the ‘sloping seas paradox’ ‘ instead !
“I might be inclined to predict the same amount of rise in Monaco and Venuce,”
Then, you’d be wrong !!

Ofunato II, Japan = 4.67
Hakodate I, Japan = -1.47-
Reykjavik, Iceland = 2.41
Ny-Alesund, Norway = -5.14-
Hirtshals, Denmark = -0.22-
Esbjerg, Denmark = 1.25
Weipa, Australia =3.09
Sydney Aus, = 0.8
Betio, Kiribati = 2.34
Easter Island = 0.08
North Sydney, Canada = 3.99
Churchill, Canada = – 8.87-
But, ALL are connected by the same seawater.
And to labour the point …
Dover, UK = 2.37; ( & 20 miles east is) Calais, France = 0.86
There is no ‘sloping seas paradox’;
The seas have never been level, ( There is a ~ 200mm difference in height between the Pacific and Atlantic Oceans ) because of a combination of … Coriolis effect, Gravitational effects ( of Planets, principally the Sun & Moon ), Wind, Air Pressure, Plate Tectonics, the Thermohaline Circulation, Salinity & Temperature variations.
Chris Barron: London is 49 feet above sea level, on the Thames River. Sea level rise and fall in various places has more to do with subsidence and rebound of the land at each location.
savenergy: Your post contains more bullshit than the squeeze chute in the isolation barn at a bull semen collection farm.
“London is 49 feet above sea level, on the Thames River”
No, it isn’t …
Average elevation: 138 ft
Minimum elevation: -10 ft
Maximum elevation: 545 ft

” the squeeze chute in the isolation barn at a bull semen collection farm.”
A place you obviously frequent, but I suppose you need to find relief/pleasure somewhere … so enjoy !!!
Elevation of the Thames River at London is 49 feet
@ Morgan Wright/wrong.
“Elevation of the Thames River at London is 49 feet”
Fascinating ! what’s your source for that number ??
Maybe you should tell the Ordnance Survey, The UK Hydrographic Office & Port of London Authority, that they’ve been getting it wrong all these years.

Fun Fact; the Thames is tidal to Teddington Lock ( West London).
Hmmm. . . so you are saying that air pressure, wind effects, saline and temperature variations stay constant at each location so the sea stays at constantly different levels at each tide gauge. Amazing!!
Even worse. Not constantly different levels, constantly different rates of rise. Good thing we weren’t talking about acceleration of rates of rise.
And don’t forget the gravitational pull of planets.
No, I’m not.
I am saying that … the Thames River at London is ‘NOT 49 feet’ above mean sea level.
The 90mile London Tideway, from Teddington Lock in the west to the sea Is tidal and includes most of its London stretch, has an average rise and fall of 23 ft (7 m). (The Port of London Authority manages this part of the river )
It is always at sea level +/- additions for … Moon phase, air pressure, wind effects, tidal surge
A flood threat comes from high tides and strong winds from the North Sea, so the Thames Barrier was built in the 1980s to protect London from this risk.
