Climate change is causing significant and far-reaching impacts on the Great Lakes and the Great Lakes region. This report, from 18 leading scientists and experts from Midwest and Canadian universities and research institutions, draws on the array of existing research to assess how the shifting global climate impacts the unique Great Lakes region.
Intense rainstorms, floods, and heat waves will become more common in the Great Lakes region due to climate change in the coming decades. While ice-cover declines will lengthen the commercial navigation season on the lakes, warmer lake temperatures will increase risks from invasive species, and could threaten water quality. Material in this report is largely a synthesis of the information contained in the National Climate Assessment’s chapters on the Midwest (Chapter 18) and Northeast (Chapter 16). Donald Scavia, GLISA's co-director, was one of the convening authors of the NCA's Midwest regional chapter; GLISA also served as a hub for the compilation of technical inputs for the Midwest chapter.
