A Changing Flood Recipe for Las Vegas
A new study shows that urbanization and climate change are changing the strength and seasonality of flooding in the Las Vegas region. Flood managers have built an extensive system of drainage ditches and detention basins to protect the public, but this engineering projects and urban development are interacting with climate change to alter the timing and intensity of flood risk.

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.

Rare Earths Find in Sweden: A Gamechanger?
A big find of raw materials critical for green technology has been announced in Sweden. Since Europe does not produce its own so-called ‘rare earths’ so far could this news be a gamechanger?

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.

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.

Concerns About Extremists Targeting U.S. Power Stations
Attacks on four power stations in Washington State over the weekend added to concerns of a possible nationwide campaign by far-right extremists to stir fears and spark civil conflict. Violent extremists “have developed credible, specific plans to attack electricity infrastructure since at least 2020, identifying the electric grid as a particularly attractive target given its interdependency with other infrastructure sectors,” the DHS said in a January.

Addressing the Needs of Underprepared Communities
Many regions in the U.S. do not have regular earthquakes. Still, they have faults that can create large earthquakes, and communities in these regions are not prepared to experience a large quake with the capacity to cause significant damage. A new center will specifically address areas of low probability of occurrence but high impact earthquake risk and seek to meet the needs of all communities for natural hazard mitigation.

Testing Environments Help Secure Transportation Infrastructure
“All critical infrastructure sectors—including the energy, manufacturing, and transportation sectors—rely heavily on sophisticated technologies like industrial control systems, cellular networks, and artificial intelligence,” said DHS S&T’s Alex Karr. “These are all accessed, monitored, and controlled via the internet, which, in turn, makes them susceptible to hacking, malware attacks, and other malicious activities.”

Majority of California's Coastal Airports Are Vulnerable to Increased Flooding Caused by Climate Change
Most of California’s population and its largest airports are located along the Pacific coastline, which is increasingly impacted by storm surges, sea level rise, and erosion due to climate change. In the next 30 years, sea level along the coast is expected to rise as much as 8 inches.

S&T Makes Headway on Infrastructure Investment
Critical infrastructure is the backbone of life as we know it here in the U.S.—there are, of course, the roads and highways we travel, but also the electric grids that power our lives and livelihoods, the public transit systems that facilitate connection, the cyber networks that enable commerce and communication, and much, much more.

Global Warming Doubled the Risk for Copenhagen’s historic 2011 Cloudburst
On 2 July 2011, the Danish capital Copenhagen suffered a cloudburst of historic proportions, causing damage and destruction costing billions of kroner. Researchers have used detailed weather models to clearly tie increased temperatures to that historic cloudburst.

Urban Street Networks and Building Density Shape Severity of Floods
Cities around the globe are experiencing increased flooding due to the compounding effects of stronger storms in a warming climate and urban growth. Researchers’ new analytical model can assess neighborhood-level hazards globally.
To Get Off Fossil fuels, America Is Going to Need a Lot More Electricians
To cut greenhouse gas emissions on pace with the best available science, the United States must prepare for a monumental increase in electricity use. Burning fossil fuels to heat homes and get around isn’t compatible with keeping the planet at a livable temperature. Appliances that can be powered by clean electricity already exist to meet all of these needs. The problem is, most houses aren’t wired to handle the load from electric heating, cooking, and clothes dryers, along with solar panels and vehicle chargers. And a shortage of skilled labor could derail efforts to “electrify everything.”
