Current modeling is inadequate because it fails to fully account
for climate variability, adaptation, and indirect effects
Place specific modeling needed since temperature,
precipitation, and soil moisture changes and water
availability varies from place to place
Average climatic changes projected to affect crop yields and the
geographic distribution of crops
Some states will gain, but other states may see substantial
losses
Some crops will be more impacted than other crops
Farmers likely to adapt to changing climate conditions
Some agricultural adaptations may be costly
Adaptation may alter land-use patterns (e.g., forests
converted into agricultural land)
Adaptation often depends on questionable availability of
water
