Top 5 things you need to know about this Great Lakes 'Super Freeze' phenomenon
- The Great Lakes have just recorded their highest ice coverage in nearly a decade, hitting over 65% coverage in early February due to an Arctic blast that created a "super freeze" effect.
- This intense ice cover is already causing shipping disruptions, with dozens of cargo ships delayed or docked at ports across Lake Superior and Lake Michigan, potentially impacting supply chains for iron ore and coal.
- Scientists are warning that the rapid ice formation could lead to a shorter lake effect snow season, but also increases the risk of dangerous "ice shoves" that can flood coastal neighborhoods in seconds.
- The frozen lakes are creating a rare "ice volcano" phenomenon near Lake Ontario, where trapped waves explode through ice cracks, shooting ice vapor up to 30 feet high—a spectacle drawing crowds and drone pilots.
- Locals are already seeing a surge in ice fishing permits, but experts urge caution as the ice thickness varies wildly, with some areas only 4 inches thick despite the freeze, posing deadly risk for unaware anglers.
