Both of Wisconsin’s Great Lakes are ecologically and culturally important to the people of Wisconsin and are home to over 3,500 different species of fish and wildlife. They provide key ecosystem services to coastal communities in Wisconsin through direct uses like fisheries and recreation and indirect uses such as water quality regulation, cultural and family identities, and psychological well-being. But climate change is one of the top concerns for the region. Given the importance of the Great Lakes to the people, plants, and animals that call them home, it is imperative that we protect them as climate changes. The WICCI Great Lakes working group assessed the current and projected impacts of climate change on Wisconsin’s Great Lakes ecosystem and developed potential solutions and adaptation strategies. This assessment provides a thorough examination of impacts, solutions, and strategies, that if acted upon, will lead to a more resilient future for the region.
