Clever thought, mantis, but I can't swallow that idea. Master Ash tells us that ice covers the entire globe in his time, which implies a cooling process. Hallvard and Typhon confirm this. If loss of plant life affected Urth's albedo so that more solar radiation were reflected, cooling might result, but a) such a change in albedo through loss of plant life seems unlikely, and b) even if there were some such change, so extreme an effect seems beyond the range of possibility.

Regrettably, it seems that Wolfe was using science obsolete even at the time of his writing when he came up with the White Fountain idea. (This is the part of UotNS I perhaps like least.) There had been a theory that the energy absorbed by black holes was some- how shunted into other dimensions or universes via what came to be known as wormholes, but the "missing" energy was adequately accounted for when the polar X-ray jets that black holes emit were discovered. We know that the White Fountain was meant to be the output of a black hole from another universe from Severian's experiences in Yesod--I believe (though I'm not sure, and I don't have the book here to check) that Apheta tells him how the White Fountain is to work. Now we know that Wolfe likes, or says he likes, generally-discred- ited scientific theories, such as Lamarckism. In "Silhouette", he even has Johann adhere to an older (and, in the story's context, obsolete) understanding of relativistic time dilation (Johann believes in the Ein- steinian model, in which the time difference can never be made up, where other characters believe that by following the exact same path back that was taken out, the time difference can be erased). So in this case, he may again be indulging his penchant for old science. But I rather think that he chose to use the Fountain for its symbolism, and let science go hang. I'm not, now that I think about it, bothered by the thought that the solution is only "temporary"; we know that Briah, or its current cycle, will come to an end in the Grand Gnab, and the Green Men, and thus the Hieros, know how to walk the corridors of time. I think that the idea is more that the premature end of life on Urth is an evil to be avoided, rather than that any end is bad. After all, to every thing there is a season, etc. And besides, the symbolic value of saving the home of humanity must be weighty to the Hierodules.
