As Reservoirs Go Dry, Mexico City and Bogotá Are Staring Down ‘Day Zero’
In Mexico City and Bogotá, reservoir levels are falling fast, and the city governments have implemented rotating water shutoffs as residents are watching their taps go dry for hours a day. Droughts in the region have grown more intense thanks to warmer winter temperatures and long-term aridification fueled by climate change. In South Africa in 2018, Cape Town beat a climate-driven water crisis, and the way it did it holds lessons for cities grappling with an El Niño-fueled drought.

The Homeowner Mutiny Leaving Florida Cities Defenseless Against Hurricanes
The only protection the town of Hendrickson, Florida, has from the Gulf of Mexico’s increasingly erratic storms is a pristine beach that draws millions of tourists every year — but that beach is disappearing fast. A series of storms have eroded most of the sand that protects Redington Shores and the towns around it, leaving residents just one big wave away from water overtaking their homes. The federal government is refusing to restore eroded beaches in Pinellas County unless homeowners agree to one condition: public access.

O-RAN Is Overhyped as Avoiding Chinese 5G Influence
In recent years, countries have faced a stark choice between Chinese and Western suppliers to develop their 5G cellular network infrastructure. While Chinese suppliers such as Huawei and ZTE are not trusted because of their ties and legal obligations to China’s party-state, Western suppliers have struggled to compete on cost. The emergence of Open Radio Access Network (O-RAN) technology has some promised, but the idea that O-RAN is a viable alternative to Chinese suppliers seems hollow.

The long view
Helping Strengthen America’s Critical Infrastructure
Everyday life depends on a robust infrastructure network that provides access to running water, communications technology and electricity, among other basic necessities. The experts who keep our national infrastructure secure and resilient also need a strong network to share their knowledge and train the next generation of professionals capable of solving complex infrastructure challenges.
AI and the Future of the U.S. Electric Grid
Despite its age, the U.S. electric grid remains one of the great workhorses of modern life. Whether it can maintain that performance over the next few years may determine how well the U.S. competes in an AI-driven world.
