A team of researchers at Nanyang Technological University, working with a group at NASA's Jet Propulsion Laboratory and another colleague at ETH Zürich, has found evidence showing that parts of many big coastal cities are sinking faster than the sea is rising. In their paper published in the journal Nature Sustainability, the group describes using satellite-based radar to measure the degree of land subsidence for 48 of the largest cities in the world.
Prior research has shown that global warming is melting ice around the world, leading to rising sea levels. This increase in sea levels is a major concern to cities and towns that lie on the edges of the sea. But many cities also face another problem—land subsidence, in which land sinks due to removal of groundwater or gas and compaction of the ground from the massive weight of buildings on top of it.
In this new effort, the researchers noted that rising sea levels compounded with sinking land could result in major problems for coastal cities in the years ahead. To learn more about the degree of the problem, the researchers accessed and analyzed radar data from NASA satellites that measure the altitude of land across the globe.

Doomed. Yawn.
Well, this is actually true, since heavy buildings that don’t rest on bedrock will sink, while the oceans aren’t really rising at all.
Too many people in them.
They can’t tip over the entire continent like Guam, so they end up just bending their little city portion of land down.
Sinking under the weight of racism! Mountains? That’s white privilege.
Building on fill will do that.
Or is Gilligan moving he stick because he is using it to tie his lobster traps?
Like this hasn’t been known forever by geographers and geologists. Subsidence due to various causes, and vertical tectonic movement, rebound from the ice age, etc.
Meanwhile the absolute sea level rise continues at its stable 2 mm a year, rain or shine. Started before “global warming” was even a thing.
Martha Vineyards almost tiped over due to those illegal aliens.
It is natural process with every continent, where the land meets the sea. The continet’s edge at the sea is continually affected by erosian from the sea and air currents, as well as continental drift. The geograhy of the continent is continually being shaped, at the continent’s edge, by all those natural forces, and subsidence is one of the results.
Yeah, buh, buh, but......wasn’t it Ubama that said, “a rising tide lifts all boats?” And, he’s got an umpty-million dollar mansion on Martha’s Vineyard so we be all good, now...
In the graph below we're currently in the small red hump to the right of the Little Ice Age. A big nothingburger relative to recent warming periods like the Medieval Warm Period, Roman Warm Period, and Minoan Warm Period. That's why historic sea levels for some ancient cities had those cities operate as port cities, though some of them today are a mile or miles (plural) away from the coast. (In the past it was warmer and the sea levels were higher, making our current rise in sea levels look like a walk in the park.)
Are they certain that the sky is not falling upward? Ask the little chicken fella!
Time to Go Long in the Wader and Life Jacket Spot Market.
Once the sea level rise hits 9mm per year, will it have to register with the EPA as a social, neo-fascist, MAGA existential threat to America?
Thank God there are some folks out there who actually know some science. Good reply, and absolutely spot on.
It’s sinking only because Trump eats too many MacDonald’s cheese burgers.
