Bits of John Wyndham's "The Kraken Wakes" (published 1953) also present rising sea levels, albeit caused by aliens intentionally melting the ice caps rather than humans accidentally doing it. In the book, most people don't care until it's too late, and then they adjust to the post-apocalyptic world with a combination of violence and resignation.
