Extreme Storms and Flood Events Cause Damage Worth Billions to Ports – and They Are Most Disruptive to Small Island Developing States
Shipping ports are crucial for the global economy. But ports, by their nature, are located in coastal areas or on large rivers and are exposed to natural hazards such as storms and floods as a result. Scientists refer to the physical damage caused by natural hazards and the monetary loss associated with port closures and reconstruction as “climate risks”. 1,340 of the world’s largest ports in terms of trade flow are vulnerable to climate risks.

Bringing Manufacturing Back to the U.S. Requires Political Will, but Success Hinges on Training American Workers
The lack of manufacturing competitiveness in the U.S. leaves the U.S. vulnerable to shortages of critical goods during times of geopolitical disruption and global competition. The strategies the U.S. employs in bringing back manufacturing, along with innovative practices, will be key to ensure national security.

Metal-Free Batteries Raise Hope for More Sustainable and Economical Grids
Rechargeable batteries that use ammonium cations as charge carriers could provide ecofriendly and sustainable substitutes to metal-ion-based batteries. Metal-ion batteries dominate the market, but they depend on limited and declining resources, which threatens long-term availability.

Growing Interest in, Planning for, Managed Retreat from High-Risk Areas
Strategically moving communities away from environmentally high-risk areas, such as vulnerable coasts, has been referred to as “managed retreat.” Of all the ways humans respond to climate-related disasters, managed retreat has been one of the most controversial due to the difficulty inherent in identifying how, when, where, and by whom such movement should take place.

Achieving Foundational Security for Food Systems
U.S. cereal crops such as corn, rice, and wheat feed hundreds of millions of Americans and millions more around the world. Ensuring active defense of these and other staple food grasses is a critical national security priority. New DARPA project seeks advanced threat-detection and warning capabilities for crop defense.

Interest in Geothermal Energy is Growing
These days, some 400 power plants in 30 countries generate electricity using steam generated beneath the earth’s surface, producing a total capacity of 16 gigawatts (GW). Despite its advantages, geothermal energy has seen limited use compared to fossil fuels, but recent energy shocks have increased interest in this energy source.

Towers in the Storm
The problem with the U.S. electrical grid is that many transmission towers have exceeded their design life by about 50 years, which means the aging grid today faces bigger chances of failure. One threat to the grid is from damaging winds of extreme storms such as hurricanes.

The long view
Scientists Map Loss of Groundwater Storage Around the World
Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink. A new study maps, for the first time, the permanent loss of aquifer storage capacity occurring globally.
