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.
Coordinated by a partnership between climate services organizations in the U.S. and Canada, this product provides a synthesis report summarizing the previous years’ climate trends, events, new research, assessments, and related activities in the Great Lakes region. The 2017 report provides an overview of the climate trends and impacts in the basin for the year, including information on the past year’s climate trends, a summary of some of the major climatic events, and a summary of relevant new climate research and activities. It was developed as a longer term trend analysis and compilation of the existing Great Lakes Region Quarterly Climate Impacts and Outlook and is intended for use by managers and practitioners at federal, state, provincial, regional, and local scales, as well as for stakeholders and the general public. The report is also available for download from binational.net.
This report synthesizes available science on the observed and projected impacts of climate change in the Great Lakes Basin and documents the climate change assessment methods applied in the region. It was initiated in support of commitments under Annex 9-Climate Change Impacts of the Great Lakes Water Quality Agreement to take into account the climate change impacts on the chemical, physical, and biological integrity of the waters of the Great Lakes and communicate and coordinate binationally regarding ongoing developments of domestic science. The report draws upon the range of research conducted by various levels of government, academia, and other organizations and the growing body of knowledge in areas of ecological research and climate change and provides researchers, managers, and decision makers with a time-stamped, thorough, and methodical examination of that climate change science.
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.
This report was designed to Identify how beachgoers perceive the risk of dangerous currents and waves in the Great Lakes; evaluate existing messages and delivery mechanisms (such as National Weather Service Surf Zone Forecasts); translate complex beach conditions into understandable, actionable messages for specific beachgoer audiences; and identify effective delivery mechanisms for specific audiences.
This booklet describes how natural processes affect the coast, including changes in lake levels, storms and storm surges, waves and wave climate, transport of sediment, ice on the shore, shoreline erosion, lakebed erosion, and movement of water on the land. It also describes how to protect coastal investments by adapting to natural processes, restoring a natural shoreline, moderating coastal erosion, armoring the shore, stabilizing bluffs and banks, controlling surface water and groundwater, building environmentally friendly shore protection structures, and working with engineers and contractors. The final section covers risk management and the economics of protecting a coastal investment, including shoreline property features and value, government regulations to protect a coastal investment, costs of shore protection, and accounting for climate change. There is also a list of resources for more information and a glossary of coastal engineering terms.
