(CNN) - By the end of the century, cities on the east coast of the U.S. could experience flooding at Hurricane Sandy levels every couple of years. That’s according to a report in the latest issue of Scientific American.
The study sites updated forecast models which predict climate change will lead to higher sea levels than previously thought.
But climate change is not just a concern for coastal cities. Today, the state of Indiana will just begin assessing flood damage to its public infrastructure. The damage was caused by record rain storms last month. Those same storms also brought flood waters to Chicago.
Those are just the latest prime examples of the new challenge many cities are facing: an increasing frequency of heavy storms, which cities are not currently designed to deal with.
To see what Chicago is doing, and how the rest of the country might be affected, we visited the control center where flood waters are managed.
What we learned from David St. Pierre, the executive director of the Metropolitan Water Reclamation District of Greater Chicago, is that climate change has arrived:
[1:00] “We are seeing these extreme rain events that we have never seen before in Chicago. After you get one 100-year rain event, everybody said, 'Well, we won’t see that in another 100 years.' And then two years later, we had another event. And this year, we had yet another. So we are seeing climate change and it is real.”
