The Great Lakes are experiencing record warmth this fall as water temperatures spike well above normal seasonal levels, fueling lake effect snow and potentially disrupting fish spawning.

The surging temperatures are most stark in Lake Superior, the northerly Great Lake notorious for its frigidity. It has never been so balmy this late into the fall and has consistently set records for its warmth, according to federal data dating back to 1995.
