Agricultural Methods/Practices-
     Climate change will require that agricultural
     methods and practices (planting dates,
     fertilization/irrigation rates, and species selection)
     change in many areas.
     If all agricultural systems are sucessfully able to
     adapt to climate change, the effects are expected
     to be positive for less than a few °C, and negative
     for more than a few °C (In the mid-latitudes).
     If agricultural systems are unable to adapt to
     climate change, there will be negative results
     regardless of the amount of warming.

Crop Yields-
     A general decrease in crop yields is projected for
     the following areas:
          Tropical/Subtropical regions
          Mid-latitudes (if warming is more than a few °C)
     A general increase in crop yields is projected for
     the following areas:
          Mid-latitudes (if warming is les than a few °C)

Food Costs-
     Most studies show that along with a temperature
     increase of a few °C comes an increase in food
     prices.

Hunger-
     Climate change will increase the number people
     with hunger risk, especially in developing countries.
     Climate change will lessen food security in Africa.

Pests/Weeds-
     Climate change will increase the range of some
     insects and weeds. This may have a negative
     effect on some crops and decrease overall yield.
