Climate Change: Extreme Events
The projection for the Great Plains and Midwest is for extreme events, such as heavy downpours, flooding, heat waves, and drought, to increase in the future. Although these events are common in this region, an increase in frequency could put extra stress on farms already feeling plenty of pressure from these losses.

Climate Change: Pests
Pest management is a persistent challenge in cropping systems. Weeds, insects, and diseases are common pest challenges, and the impacts are often influenced by weather conditions. Changing weather conditions will alter the frequency, type, and intensity of pest pressure. For example, the increase in humidity in the Midwest has created favorable conditions for diseases and pathogens. Also, warmer temperatures and an extended growing season have enabled the northward expansion and increased likelihood for overwintering
