After extreme weather events like Hurricane Harvey, city planners need to think about the smartest way to rebuild. Here are some no-regrets infrastructure investment ideas.
The financial impact of Hurricane Katrina on individual lives has been little studied until now.
Researchers examined credit data on the victims of Hurricane Katrina to understand how the disaster affected their personal finances, revealing important lessons for those hurt by Harvey.

The Acros Fukuoka eco-building in Fukuoka, Japan boasts one of the world’s most famous green roofs. The GRIT Lab at the University of Toronto is working to bring green roofs to the city and beyond in order to combat climate change.
Green roofs could play a critical role in helping cities cope with extreme rainfall events in the age of climate change. The roofs essentially suck up stormwater like sponges if designed properly.
