“Melting of the Thwaites Glacier could rewrite the global coastline” Dec 15, 2021https://www.pbs.org/newshour/show/melting-of-the-thwaites-glacier-could-rewrite-the-global-coastline
William Brangham: .. A warming atmosphere is creating serious problems in the Arctic Circle and on the continent of Antarctica. … in Antarctica, a key ice shelf that sits in front of the Thwaites Glacier could break up much sooner than expected, within five years. Joining me now is David Holland. He studies atmospheric and ocean sciences at New York University …
David Holland: .. We have been seeing for the last couple of decades a large change in Antarctica and, in particular, on this one glacier called Thwaites in West Antarctica. .. It’s actually largely in the ocean. And the ocean can, in theory, easily melt it .. Warm ocean waters have arrived at this glacier, and they’re melting it like crazy. …
William Brangham: So, if that ice shelf were to break up, and Thwaites were to move into the ocean, what kind of impacts are we talking about?
David Holland: It would be absolutely massive, on the time scale of the last century, what we’d seen. We would see a dramatic rise of several feet of sea level. And it could be Thwaites itself perhaps two to three feet, but Thwaites is holding back its neighbors. And they, too, could fall apart, raising sea level by an additional maybe six feet, so, altogether, something of scale 10 feet. And if you try to wrap your head around that, we’re talking around the entire Earth, the entire ocean. It’s a massive amount of water. It’s a rewriting of the global coastline in that sense. …..
So, if you were wondering how James Hanson’s “swamping of the Manhattan West Side Freeway” prediction was going to happen within his ever-shortening deadline, there ya go.

Excerpt:
“Rivers and Seas Are Boiling!”
Ocean levels have been rising since the last Ice Age. Global sea levels have been naturally rising for ~20,000 years. There is no evidence of an acceleration of ocean-level rise, and therefore no evidence of any effect of mankind on sea levels. According to tide gauges, ocean levels are rising less than the thickness of one nickel (1.95 mm thick) per year or about the thickness of one penny (1.52 mm thick) a year.45
The 2018 “State of the Climate Report” by Norwegian professor Ole Humlum explained, “Data from tide gauges all over the world suggest an average global sea-level rise of 1–1.5 mm/year, while the satellite record suggests a rise of about 3.2 mm/year. The large difference between the two data sets still has no broadly accepted explanation.”46
As former NASA climatologist Dr. Roy Spencer’s research has shown, “Sea level rise, which was occurring long before humans could be blamed, has not accelerated and still amounts to only 1 inch every 10 years.”47
University of Pennsylvania geologist Robert Giegengack has said, “At the present rate of sea-level rise it’s going to take 3,500 years to get up there [to Al Gore’s predicted rise of 20 feet]. So if for some reason this warming process that melts ice is cutting loose and accelerating, sea level doesn’t know it. And sea level, we think, is the best indicator of global warming.”48
Spencer’s research on Miami flooding and sea-level rise found “that flooding is mostly a combination of 1) natural sea-level rise (I show there has been no acceleration of sea-level rise beyond what was already happening since the 1800s), and 2) satellite-measured sinking of the reclaimed swamps that have been built upon for over 100 years in Miami Beach.”
