How Well-Managed Dams and Smart Forecasting Can Limit Flooding as Extreme Storms Become More Common in a Warming World
The United States is home to over 50,000 operable reservoirs that are overseen by dozens of state and federal agencies. As rising global temperatures make extreme storms more common, the nation’s dams and reservoirs – crucial to keeping communities dry – are being tested.

Germany Will Rely on Imports for Its Growing Hydrogen Needs
Revisiting its national hydrogen strategy (NHS), the German government foresees a huge need for hydrogen. By 2030, hydrogen consumption may hit 130 terawatt hours — that is more than one-fifth of all current electricity consumption in Germany. But Germany will need to import as much as 70% of it.

An American View on U.S. Investment in Critical-Mineral Mining in Australia
In May, the United States and Australia signed a compact which, among other things, aims to coordinate policies and investments to support the expansion and diversification of critical minerals supply chains. In this case, diversification basically equates to reducing dependence on China, in which various links in the critical-mineral supply chain are heavily concentrated.

One- to Four-Family Properties with Multiple Losses Insured by the National Flood Insurance Program
What are the characteristics of properties that have experienced multiple flood losses (e.g., percentage of overall claims payments, number of losses, and structure characteristics)? What are the socioeconomic characteristics of multiple loss property (MLP) households and the communities in which they are located? What percentage of MLPs have been mitigated, what are the socioeconomics characteristics of neighborhoods where MLPs have been mitigated, and how effective has mitigation been in reducing risk?

The Ground Is Deforming, and Buildings Aren’t Ready
There is a “silent hazard” lurking underneath our major global cities, and our buildings were not designed to handle it. With Chicago as a living lab space, Northwestern study links underground climate change to variations beneath urban areas.

Florida’s Home Insurance Crisis Isn’t Going Away
It’s hard to make money selling home insurance in Florida. For one thing, the state is very vulnerable to hurricanes, and those hurricanes are getting stronger thanks to climate change. A legal loophole has made the state a hotbed for fraudulent litigation over insurance claims, and companies lose even more money fighting those lawsuits. And reinsurers are charging insurance companies much higher fees owing to climate change-driven disaster losses.

Can We Use Plastic Waste to Build Roads, Buildings, and More?
A new study examines the current status, challenges, and needs of recycling plastics in a circular economy, and examine the long-term durability and environmental costs of doing so for use in infrastructure. Stanford engineers Zhiye Li and Michael Lepech discuss the potential for reusing discarded plastic in infrastructure applications.

Energy Agency Says Global Thirst for Oil Finally May Be Topping Out
Is the globe’s thirst for oil finally topping out? A major international energy watcher says yes, predicting last month that demand for global oil for transport will peak around 2026, plateau for all uses by 2028, and possibly hit a zenith by the end of the decade. This would be great news for environment, expert say, but issues in developing world may foil hopes.

Nuclear Has Changed. Will the U.S. Change with It?
Fueled by artificial intelligence, cloud service providers, and ambitious new climate regulations, U.S. demand for carbon-free electricity is on the rise. In response, analysts and lawmakers are taking a fresh look at a controversial energy source: nuclear power.
Water Is the Other U.S.-Mexico Border Crisis, and the Supply Crunch Is Getting Worse
The United States and Mexico are aware of the political and economic importance of the border region. But if water scarcity worsens, it could supplant other border priorities. The two countries should recognize that conditions are deteriorating and update the existing cross-border governance regime so that it reflects today’s new water realities.
Exploring the New Nuclear Energy Landscape
In the last few years, the U.S. has seen a resurgence of interest in nuclear energy and its potential for helping meet the nation’s growing demands for clean electricity and energy security. Meanwhile, nuclear energy technologies themselves have advanced, opening up new possibilities for their use.
