By "transpiring" more heavily than the prairie grasses that preceded them,
and in relatively short periods, crops can generate air movements that can
lead to storms, and intensify the season during which water is cycled
through the atmosphere.


So presumably the results are only intended to apply to North America,
since AIUI most of Britain was covered by forest before it was cleared
for agriculture. I would imagine that a given area of fairly dense
forest would lose more in transpiration than the same area of corn.
