For cold related SF, Alan Dean Foster wrote an entire trilogy about an ice planet called Tran-Ky-Ky. It's set in the Humanx Commonwealth universe. I have the entire trilogy on my shelves if you want to read it. For readers of your LJ who do not live in the same house with me, the novels are: Icerigger, Mission to Molokai, and The Deluge Drivers. I imagine that they're out of print, that doesn't mean that used copies can't be found.
