NC- Researchers say get ready for more floods, contamination

Climate change is causing hurricane-related flooding to increase — along with the cost to recover from these storms — and communities should prepare now. That’s what two researchers recommended during a recent Duke University-hosted media briefing on hurricane preparedness and impacts.

“The biggest change in storm activity for North Carolina is not the frequency of landfalling hurricanes. It’s not even the intensity of these hurricanes. It’s the rainfall. It’s the amount of water that these storms contain,” said Dr. Megan Mullin of the Duke Nicholas School of the Environment.

Mullin, a professor of environmental politics who researches the politics of climate change, including local political response to climate risks, teamed up for the briefing last week with Dr. Lee Ferguson, an environmental chemist at Duke and one of the lead scientists investigating the Cape Fear’s Gen X contamination.

“Intensity of flooding is our biggest impact from the changes in storm behavior as a result of climate change, and that impact is reaching more broadly and getting more expensive,” Mullin said. “It’s getting more expensive for communities to clean up. It’s getting more expensive for the utilities. It’s getting more expensive for the farmers who will lose an entire year of crops and more expensive for individuals who are experiencing the disruptions.”

Communities are making progress planning for hurricanes, but obstacles remain, Mullin said, like lack of resources and urgency to recover and return to normalcy after a storm.

Ferguson is an associate professor of civil and environmental engineering who studies the effects of flooding and the potential for contamination from chemical plants, hog farms and wastewater treatment systems.

He explained that the state has contaminant sources that are active almost all the time, and there are always at least low-level inputs from these sources into waterways.
