An assessment of the impacts of climate change on the Great Lakes: 2025 report This report confirms climate change is affecting the Great Lakes region through warmer and wetter weather, greater fluctuation in lake levels and disappearing fish populations.

📄 A new report out of the @elpcenter.bsky.social highlights how climate change is affecting the Great Lakes — warmer waters, less ice cover, and shifting ecosystems. See what the data show:
