Generally speaking, the most serious damage to artifacts is caused
by the climate extremes.  "Representative climate" is usually not a
good measure of the climate extremes.  We believe that the
appropriate strategy is to determine the types of climate extremes
to which the collection is sensitive, and then monitor the locations
where those extremes are most likely to occur.
