NEW YORK — If rising oceans aren't worry enough, add this to the risks New York City faces: The metropolis is slowly sinking under the weight of its skyscrapers, homes, asphalt and humanity itself.
New research estimates the city's landmass is sinking at an average rate of 1 to 2 millimeters per year, something referred to as "subsidence."
That natural process happens everywhere as ground is compressed, but the study published recently in the journal Earth's Future sought to estimate how the massive weight of the city itself is hurrying things along.
More than 1 million buildings are spread across the city's five boroughs. The research team calculated that all those structures add up to about 1.7 trillion tons of concrete, metal and glass — about the mass of 4,700 Empire State buildings — pressing down on the Earth.
The rate of compression varies throughout the city. Midtown Manhattan's skyscrapers are largely built on rock, which compresses very little, while some parts of Brooklyn, Queens and downtown Manhattan are on looser soil and sinking faster, the study revealed.
While the process is slow, lead researcher Tom Parsons of the U.S. Geological Survey said parts of the city will eventually be under water.
"It's inevitable. The ground is going down, and the water's coming up. At some point, those two levels will meet," said Parsons, whose job is to forecast hazardous events from earthquakes and tsunamis to incremental shifts of the ground below us.
But no need to invest in life preservers just yet, Parsons assured.

“What’s the +/- on this sinking claim?”
Good point! And what is the +/- on the ocean rising claim or for that matter the measured rising claim? Is the ocean really rising at all or do the enviros just throw that out along with their “undisputed” stuff?
There’s a site on youtube called “climate news network.” I’m surprised youtube allows it to exist
The have provided sea-level measurements at major ports in Europe, New York, etc... over the last century (where accurate measurements are available)
The average sea-rise over that time is something like 1 centimeter.
“As rising oceans threaten NYC”
A so called news org puts BS like that at the front of the headline.
This is who has been measuring things. https://www.google.com/search?q=gilligan%27s+island+sinking&oq=gilligan%27s+island+sinking&aqs=edge..69i57j0i22i30j0i390i650l4j69i64.8408j0j1&sourceid=chrome&ie=UTF-8&safe=active&ssui=on#fpstate=ive&vld=cid:048e1625,vid:yLjadAyHLgI
*ROFLMAO*
Rep. Hank Johnson claims Manhattan is going to flip over because of all the weight...
The END is NEAR! /s
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.
Try
1 mm = 0.0393701 inches.
So 12/0.0393 = 305. that means it would take 305 years to sink 12 inches or 1 foot.
Rising oceans?! Where, seriously, and how soon. I read recently that no one alive today will see a noticable rise in their lifetime.
The “experts” have been howling about rising oceans since the 1960s:

At this point if they say the sky is blue I walk outside and check for myself.
that pretty much sums it up
1 millimeter = 0.04 inches or 25 millimeters = 1 inch.
Someone correct me if I’m wrong... but didn’t they at one time sink ships and cover them with stone and dirt to create more land in San Fagcisco to build on?
If all that compresses or slips at the same time I imagine the results would be biblical.
I corrected it already....wayyyyy back in the posts
People need to understand how geology works and accept that change is always happening to the continents, mountain ranges, and elevations of locales globally. But, yes the 1.7 trillion tons of weight for concrete, metals, and other substances does have an impact. However, that’s just a small speck in the big scheme of things for planet Earth.
The version I always heard was that the rock taken out weighed more than the skyscrapers that were built.
As for buildings that aren’t skyscrapers built on land that isn’t bedrock, is sinking usually that much of a problem?
The next version of West Side Story will be very interesting, but stupid. Flooding San Francisco would get rid of the stink there.
