In just seven years, between 2013 and 2020, Lake Michigan water levels swung six feet marking both record highs and record lows due to the changing climate. [source] Climate scientists attribute the volatility to the interplay of the region’s rising temperatures and precipitation from more frequent and intense storms.

These frequent intense storms bring stronger winds and conditions that exacerbate shoreline erosion and amplify flood risks. [source] Increasingly severe flooding overwhelms sewer systems and leads to basement backups and flooded neighborhoods, putting our most vulnerable people at the greatest risk.

The area’s annual precipitation has increased by about 15% since 1950. [source] These heavier rains increase the runoff of pollutants and contamination into waterways jeopardizing human health, fish and aquatic life, wildlife, and drinking water sources.

Researchers predict the area could see a temperature rise between 2.5 to 7.5 degrees Fahrenheit by the middle of this century. [source] Those heat impacts are multiplied in urban areas where the heat island effect from extensive concrete and lack of tree cover disproportionately impacts historically underserved areas.

Rising temperatures and storm events cause cold and cool water fish populations and other species to move further upstream or be removed completely. This decreases biodiversity and enables the spread of invasive species. [source]

Results from a survey of 241 municipalities in the Great Lakes Basin show coastal damage from climate change in these regions will cost at least $1.94 billion over the next five years. [source]
