The Great Lakes are feeling the heat from climate change. As the world’s largest freshwater system warms, it is poised to systematically alter life for local wildlife and the tribes that depend on it, and the warming could also provide a glimpse of what is happening on a more global level.

Total ice cover on Lake Superior (center), which is the largest, deepest and coldest of the five lakes, has shrunk by about 20 percent over the past 37 years. Though the change has made for longer, warmer summers, it’s a problem because ice is crucial for keeping water from evaporating and it regulates the natural cycles of the Great Lakes (click here for more information).
