Is climate change driving rapid shifts in water levels on the Great Lakes?

Rapid changes in weather and water supply conditions across the Great Lakes and upper Midwest are already challenging water management policy, engineering infrastructure and human behavior

The North American Great Lakes contain about one-fifth of the world’s surface fresh water. In May, new high water level records were set on Lakes Erie and Superior, and there has been widespread flooding across Lake Ontario for the second time in three years. These events coincide with persistent precipitation and severe flooding across much of central North America.
