Fascinating read, but I don't appreciate the clickbait title. Why not use the actual title, which is a much better description? "Memories of the End of the Last Ice Age, from Those Who Were There." There's not much in the actual article about scientists having ignored ancient flooding tales and suddenly paying attention.
Much more about all the stories scientists may choose to ignore is found in the book "Hamlet's Mill" [<a href="https://en.wikipedia.org/wiki/Hamlet%27s_Mill" rel="nofollow">https://en.wikipedia.org/wiki/Hamlet%27s_Mill</a>], which was "severely criticized by academics" after publication in 1969. Like most out-of-the-orthodox-mainstream evidence of its day (and nearly-all unorthodox ideas in Wikipedia today).
