Baum, Seth D. (2015) Confronting the threat of nuclear winter, Futures, vol. 72, pp. 69–79.
Contains a brief discussion of refuges in section 4.2 (p. 7).
http://gcrinstitute.org/papers/020_nuclear-winter.pdf contains the following paragraph on refuges.
I think it'd sort of be nice for this wiki entry's bibliography to be sufficiently comprehensive that it points people to this, but maybe if we'd accept everything that has just one paragraph of relevant stuff bibliography's would get too big? But maybe it's fine if we only accept one-paragraph-only things if they're by people associated with the EA community or are explicitly related to EA cause areas (rather than just somewhat related - e.g., related to extreme nuclear winter rather than just any nuclear conflict), and if the bibliography references always point people to the right page number(s)? Not sure.
