Wisconsin Initiative on Climate Change Impacts (WICCI) - Regional Models

Wisconsin Initiative on Climate Change Impacts (WICCI) Climate Working Group created and maintains regional, down-scaled global climate models to demonstrate how Wisconsin's climate has been changing and project how it might change in the years to come. A number of methods have been developed to derive detailed regional and local climate data in order to evaluate the potential impacts of climate change by incorporating landscape features, water bodies, or other characteristics that may influence regional or local climate into global models. 

These models are used by the other WICCI working groups to look at ways climate change might impact a variety of natural resources, ecosystems, infrastructure and economic activities. The results can also be used by government agencies, communities, businesses, organizations, and individuals to help them think about changes that Wisconsin might experience in coming decades, what those changes could mean, and, if necessary, how to develop adaptation strategies to cope with them.

From the Climate Change portion of the website, users can view a slideshow of recent results, visit an interactive mapping page, or download PDFs of maps generated from down-scaled modeling results. These tools are useful for policy and decision makers in producing future scenarios for adaptation planning.
