Columbia University’s Lamont-Doherty Earth Observatory... say researchers examining signs of past sea levels along various coasts may have failed to accurately correct for long-term ups and downs of the land itself. Based on newly sophisticated measurements made across the Bahamas along with new methods of analyzing data, the researchers produced lower—though still daunting—estimates for the last interglacial. They say seas peaked at least 1.2 meters (4 feet) higher than today—roughly in line with most current models for the next 100 years of so. However, they say, levels could have been higher. An unlikely upper limit, they say, is 5.3 meters (17 feet).
...[A]s ice sheets build, they depress the land beneath them. The ice that covered northern North America during the last glaciation up to around 15,000 years ago squashed the land down hundreds of meters. But the Earth is elastic: What goes down in one place goes up someplace else, like when you squeeze a rubber ball or an inner tube. These corollary deformations outside the icy regions are still poorly understood; they may creep for hundreds or thousands of miles over hundreds or thousand of years. They move mainly in the pliable mantle, some 100 to 1,000 kilometers down, before bulging back on the surface. Then, when the ice melts, the process goes in reverse; previously ice-covered regions rebound, while those on the fringes sink, in slow seesaw fashion.
...[S]uch movements, known as glacial isostatic rebound, can skew estimates of past water levels...For instance, previous studies have suggested that topographic ripples from North America’s glaciations have traveled down the U.S. East Coast and reached all the way to the Bahamas archipelago. This pushed the islands upward when the ice was high, and slowly eased them back down when the ice melted.

Neither are the rest of the elites who attended Obama’s birthday bash.
Two sets of forces, one is dynamic and the other is elastic in response to the dynamic; forming a certain “equilibrium” in the macro-geological sense.
Like the other adaptations in LIFE WRIT LARGE performed 24/7/365 for all earth’s ages, life on earth goes on and it will continue to go on for many ages to come.
Says everything you need to know about "Global Warming" and melting ice caps.
FWIW, there is currently no sea level rise. Rather, the ground is sinking in some places, rising in others, and stable in others. That’s why the sea seems to be rising in SOME places, yet receding in others.
It’s what has been going on for millennia.
Land masses rise and fall, this is well known. It’s why measurements must distinguish between absolute and relative sea level,
There are islands in the Pacific that the Marines fought the Japs on that were literally 4 feet ASL. They are still there. No changes.
the idiots that are scared of tidal change are the same idiots that embrace and promote sex change...
Truth is they don’t have a f*cking clue.
Think about it...Since the industrial revolution, human beings have managed to change the course of climate. Even the concept is ridiculous.

I scanned through a book about Tampa Bays beaches... Except for buildings on the beaches, it looks the same...
Thank you for posting this well written and easily understandable article based upon actual research about sea levels and the corresponding rise and sinking of land levels.
Behind the times much? Being colorblind (sociologically) is now racist. So is writing logical posts on FR.
So I think we’re definitely being swamped with something.
The ocean has been rising steadily for thousands of years, since the last ice age. It will continue to rise until the earth reaches peak interglacial then it will commence to subside as more ice accretes.
The Bahamas are a series of coral reefs. Junk data from global warming idiots
