The climate of the Midwestern states is already changing. Annual average temperatures have risen in recent decades, with the largest increases in the winter months. Extreme heat events are occurring more frequently, and heavy downpours are becoming much more common as well. The duration of lake ice, including on the Great Lakes, is decreasing, and the growing season is starting earlier and lasting longer.
