limited to only a fairly small number of schools and to much larger reductions in class size.
Second, nearly every impact of importance is driven by what is liable to
happen to the climate
on the regional to local
scale, but it is well known that current global -
scale models have
limited ability to simulate climate effects as this degree of spatial resolution.
