Detroit Is Not Built to Handle Climate Change
When flooding rains filled freeways and drenched basements across Metro Detroit in 2014, it was considered a 100-year flooding event.
It happened again over the weekend, with twice the normal amount of June rainfall happening within a few hours. Another heavy rain event is a certainty — and it’s likely it will be worse.
Jonathan Overpeck is the Dean of the School for Environment and Sustainability at the University of Michigan. He says the warming of Earth’s atmosphere will make once-uncommon weather events the new normal.
“There are two things going on here: One is certainly climate change making the problem worse. And the second thing is our infrastructure wasn’t designed for climate change.” —Jonathan Overpeck, School for the Environment and Sustainability at the University of Michigan
“As the atmosphere warms up, it can hold more moisture. And when it rains, it can dump more moisture faster. And in the Great Lakes region, we’ve seen for over a 40% increase in the most intense precipitation. So this is a big event, the 2014 event was big. But we’ve had other floods around the Midwest that have been really notable and they’ve kept farmers from planting as early as they’d like. They’ve busted huge dams up in Midland area, releasing a lot of water and causing mayhem downstream as lakes gateway. So this is all related to climate change.”
He says climate change is exacerbating the problem and that aging infrastructure isn’t equipped to deal with today’s extreme weather.
“There are two things going on here: One is certainly climate change making the problem worse. And the second thing is our infrastructure wasn’t designed for climate change and the scale of the climate extremes that we’re getting today. So we have to do two things: We have to work hard to stop climate change, or else the events will just get worse and worse. The rainfall, the flooding, will get bigger and bigger,” he says.
