The Great Lakes see the impact of climate change: "The highs are getting higher and the lows are getting lower"

More intense storms, fueled by climate change, are battering shorelines and cities throughout the Great Lakes, pulling the land right out from under some homes. 

"Cities like Chicago, Milwaukee, Detroit, Cleveland, they all have to adapt to this," said Melissa Scanlan, director of the Center for Water Policy at the University of Wisconsin, Milwaukee. 

Milwaukee sits on Lake Michigan, which has swung from record-low water levels in 2013 to record highs the past few years.
