"Fermi and Frost" is a science fiction short story by American writer Frederik Pohl, first published in the January 1985 issue of Isaac Asimov's Science Fiction Magazine.
Recognized by a fan, he is offered a seat on a plane escaping to Iceland.
Though Reykjavík is destroyed by a thermonuclear warhead, the rest of the island is unharmed.
The survivors take advantage of Iceland's geology and experience with cold weather to prepare for the nuclear winter that follows.
Interwoven into the story is speculation about the Fermi paradox and the perspective on the possibility of alien life given the prospects of nuclear war.
