EPA has assembled a website of state-by state estimates
of climate change impacts estimated by the HadCM2
global climate model (which takes into account increase in greenhouse gases and cooling effects of aerosols)
for the era near 2100. While considerable uncertainty accompanies the accuracy of the climate changes, the
site is informative in considering the number of different agricultural, water resource, human health and
natural ecosystem changes that might occur.
