Newspapers may have said that, scientists did not, and would not have done. I mean the maximum is about 70m rise if everything melted, and while that would mess all the coastal cities, the adjective "costal" is important. Also the worst case heating isn't expected for a while yet, and the "ice age" discussion that sometimes gets mentioned was on the scale of millennia, not decades.
True, but most people's information to access about the issue is from the media. Most people do not have subscriptions to journals, or any decent subsitute.
Media reports also quote scientists, so while the GP's claim is incorrect and exaggerated, there have been plenty of badly wrong predictions in the media that do quote scientists - e.g. https://web.archive.org/web/20100212233059/http://www.indepe...
IMO this is why newspapers are so afraid of LLMs, they're competing on the sense of authoritativeness.
It was very impressive, and left an impression on me which I still carry. And yet, it doesn't match reality or anything close to it.
And yes, you can argure that it was not setup by scientists - after all it was in the "Natural History" museum, which is probably not the ideal venue. But you get quickly into "No true Scotsman" territory when you discount every source that is found afterwards to be false.
