A number of
rivers are known to have reversed the direction of their flow, either permanently or temporarily, in response to geological activity, weather events,
climate change , or direct human intervention.

^ These reversals represent a return to the Chicago River's original natural outlet in Lake Michigan.
^ Reversals of the Chicago River have been increasing in frequency in association with
global warming , and may soon occur at least once each year.
