Confronting Climate Change in the U.S. Midwest (2009)

September 2009
Midwestern states could face dramatic changes including increases in the number of extreme heat days, heavier rains in the spring, and an expansion of crop-damaging pests.

A series of reports by Union of Concerned Scientists (UCS) and leading climate scientists provides an in-depth look at the potential consequences of climate change in the U.S. Midwest. The Confronting Climate Change in the U.S. Midwest series shows that without strong action to reduce heat-trapping emissions, midwestern states could face dramatic changes including increases in the number of extreme heat days, heavier rains in the spring causing delays in agricultural planting, and an expansion of the range for crop-damaging pests.

However, the report also shows that with strong action in the Midwest, and the nation, many of these worst consequences of climate changes could be avoided. Many opportunities to reduce heat-trapping emissions are ready and available today and would help put the region on the path to a clean energy future and be an example to the nation.
