We can't assume it's natural because one of the Great Beasts (Erebus) 
lives in/on/as a volcanic mountain itself. They sap energy from Urth the 
same way the black beans/worms sap the old sun. This, combined with the 
19th century refrigeration model gleaned from old books that are the 
source of other similar misteachings, more than explain the apparent 
deviation from 1981 geology.

Gene Wolfe is a very hard SF writer when he wishes to be; in "How I Lost 
the Second World War and Helped Turn Back the German Invasion" , victory 
in a motor race hinges on the quantum mechanical workings of the 
transistor.
