You can find the "scientific" reports yourself, if you really want to.
Not really. For example, the quoted text in that linked article:
An Associated Press headline from 1989 read "Rising seas could obliterate nations: U.N. officials." The article detailed a U.N. environmental official warning that entire nations would be eliminated if the world failed to reverse warming by 2000.
... cannot be found, by Google, so the article that supposedly " detailed a U.N. environmental official warning" cannot be traced. It is unclear what report it refers to, and whether is was an accurate quote or summary, assuming the report even exists.
