Climate Change in Minnesota
Minnesota is already experiencing impacts from climate change, and will continue to experience impacts to our ecosystems, natural resources, and infrastructure.
Key impacts of climate change in Minnesota
- During the summer, public health and quality of life, especially in cities, will be negatively affected by increasing heat waves, reduced air quality, and increasing insect and waterborne diseases. In the winter, warming will have mixed impacts.
- The likely increase in precipitation in winter and spring, more heavy downpours, and greater evaporation in summer would lead to more periods of both floods and water deficits.
- While the longer growing season provides the potential for increased crop yields, increases in heat waves, floods, droughts, insects, and weeds will present increasing challenges to managing crops, livestock, and forests.
- Native species are very likely to face increasing threats from rapidly changing climate conditions, pests, diseases, and invasive species moving in from warmer regions.
The MPCA participates in the Minnesota Interagency Climate Adaptation Team, formed in 2009. More detail on expected changes in Minnesota is available in the team's initial report, published in August 2010 and available on the Adapting to a Changing Climate page.
