I’VE MENTIONED FALLEN ANGELS BEFORE, the greenhouse/ice-age novel by Larry Niven, Jerry Pournelle, and Mike Flynn. It’s worth noting that you can also get it in electronic form via the Baen Free Library (thanks to reader John Chalupa for the tip).

And speaking of ice ages returning, John Ringo emails that his new science fiction novel, The Last Centurion, is based on a similar theme, and that reports of snow in Spokane in June have him worried he might have been ahead of the curve: “I wrote the damned thing spring of 2007 when eveything seemed fairly on track for normal temps. Given that serious climatologists are now discussing ‘mini-iceage’ I’m getting the puckering feeling Cassandra probably got.” Hey, Cassandra was always right. People forget that . . . .

I haven’t read the book, but I see from the Amazon page that it’s written “blog-style.” That’s kind of cool.
