Communities should plan defenses and emergency responses based on the climate of the future, not the past

“Over the past year alone, catastrophic rain events characterized as once-in-500-year or even once-in-1,000-year events have flooded West Virginia, Texas, Oklahoma, South Carolina and now Louisiana, sweeping in billions of dollars of property damage and deaths along with the high waters.

These extreme weather events are forcing many communities to confront what could signal a new climate change normal. Now many are asking themselves: Are they doing enough to plan for and to adapt to large rain events that climate scientists predict will become more frequent and more intense as global temperatures continue to rise?

The answer in many communities is no, it’s not enough.

They could be doing much, much more to adapt—not just people and how they respond to climate change, but homes, buildings, roads, and levees and other infrastructure, said Gavin Smith, director of the Department of Homeland Security’s Coastal Resilience Center of Excellence and a research professor at the University of North Carolina’s Department of City and Regional Planning.”
