How Might Global Climate Change Affect Life on Earth?
ESU501  Agriculture Impacts

It is obvious that climate change will affect agriculture, but the complexity of the climate system makes it hard to make exact predictions. Increases in temperature can have both positive and negative effects. Some locations may experience higher crop yields while others will experience declines.



Major declines in U.S. corn yields correspond to extreme climate events such as floods and droughts. Record flooding in the Midwest in 1993 flooded many corn fields and forced farmers to plant later than normal. Declines in 1995 were the result of an unusually cool, wet spring followed by a hot, dry summer.
