Climate change affects U.S. agriculture, livestock and forests in many ways.  Beyond variations in temperature, the effects can extend to precipitation, water availability, frequency of extreme events, and increased outbreaks of pests and disease, all of which can have an impact on productivity. The Climate Change Program Office (CCPO) coordinates across USDA and other Federal agencies to help ensure that the effects of climate change are understood and that farmers, ranchers and forest land managers are positioned to manage these risks.
