The US Army Corps of Engineers must now consider climate change in water projects

The US Army Corps of Engineers has new rules for how it plans water projects. It must now consider how climate change will affect these projects, like rising sea levels or more intense storms.

For decades, the Corps of Engineers planned major infrastructure projects based on historical weather data. This meant they often built for a past climate, not the one coming. Now, they have to use forward-looking climate science, which will change how they design everything from flood control to navigation channels. This shift means new projects will likely be more expensive, but also more resilient to future climate impacts.
