A Tropical Storm in California? Warmer Waters and El Niño Made It Possible.
Tropical Storm Hilary made landfall in Mexico and crossed into California last weekend, knocking out power and drenching wide swaths of southern California. Los Angeles received 2.48 inches of rain on Sunday, breaking a single-day record from 1906 of 0.03 inches. Storm Hilary adds to the lengthy list of climate-fueled disasters this summer.

Sediment Movement During Hurricane Harvey Could Negatively Impact Future Flooding
Enormous amounts of sediment, or sand and mud, flowed through Houston waterways during Hurricane Harvey in 2017, due in part to modifications made by humans to bayous, rivers and streams over the past century. Harvey was the largest rainfall event in U.S. history, and it moved 27 million cubic meters of sediment, or 16 Astrodomes, through Houston waterways and reservoirs. This could seriously impact future flooding events and be costly to the City of Houston.

Standardizing Encryption Algorithms That Can Resist Attack by Quantum Computers
Last year, the National Institute of Standards and Technology (NIST) selected four algorithms designed to withstand attack by quantum computers. Now the agency has begun the process of standardizing these algorithms — the final step before making these mathematical tools available so that organizations around the world can integrate them into their encryption infrastructure. Three new algorithms are expected to be ready for use in 2024. Others will follow.

Thermal Battery Helps Industry Eliminate Fossil Fuels
The explosion of renewable energy projects around the globe is leading to a saturation problem. As more renewable power contributes to the grid, the value of electricity is plummeting during the times of day when wind and solar hit peak productivity. The problem is limiting renewable energy investments in some of the sunniest and windiest places in the world. Antora Energy is commercializing a thermal battery that lets manufacturers use renewable energy around the clock.

Wastewater Can Help Tackle Water Shortages
Europe has experienced severe heat and drought over the last few summers, and 2023 has been no different. Vast swathes of Central and Southern Europe are simply too dry from a lack of rainfall. Water shortages are causing tensions in some countries. But, for now, there’s enough water to go around. Using the precious resource more efficiently is key.

Scientists Are Helping Cities Adapt to Extreme Heat
Extreme heat is dangerous and is one of the leading causes of weather-related deaths, and in a warming world, extreme heat is becoming the norm, not the exception. Scientists are working to mitigate the effects of extreme heat by developing strategies to build heat resilience which would allow communities to adapt to and thrive in a warming climate.

Wildfires Are Much Worse Than a Sign of Climate Change
Summer headlines have screamed of climate extremes: Record temperatures, an ocean heat wave, and rampant wildfires. The fires present a dual problem: Not only are they a symptom of climate change — becoming bigger, hotter, and more common in regions where they can affect large population centers — but they also make the crisis worse. By burning vast layers of partially decomposed vegetable matter called peat, fires like those in Canada release even more greenhouse gases into the atmosphere.

Climate Change and U.S. Property Insurance: A Stormy Mix
Accelerating risks and damage from climate change are spurring private insurers in the United States to limit coverage in a growing number of areas, thus imposing mounting stress on local communities and straining the country’s overall economic health.

AI Cyber Challenge Aims to Secure Nation’s Most Critical Software
In an increasingly interconnected world, software undergirds everything from financial systems to public utilities. As software enables modern life and drives productivity, it also creates an expanding attack surface for malicious actors. This surface includes critical infrastructure, which is especially vulnerable to cyberattacks given the lack of tools capable of securing systems at scale. New competition challenges the nation’s top AI and cybersecurity talent to automatically find and fix software vulnerabilities, defend critical infrastructure from cyberattacks.

AI-Controlled Weapons Should Be Banned from the Battlefield: Experts
AI expert says autonomous systems being used in the current Ukraine conflict need to be prohibited in the same way as chemical and biological weapons. “I’m quite hopeful that we will, at some point, decide that autonomous weapons also be added to the lists of terrible ways to fight war like chemical weapons, like biological weapons. What worries me is that in most cases, we’ve only regulated various technologies for fighting after we’ve seen the horrors of them being misused in battle,” he says.

Feds Ease Up on Colorado River Restrictions — for Now
The water shortage crisis on the Colorado River is improving, but it’s far from over. The water levels in the river’s two main reservoirs have begun to stabilize, lessening the need for states in the Southwest to cut their water usage. This year’s wet winter helped save the river from collapse, but a reckoning is on the horizon.

Geoengineering Sounds Like a Quick Climate Fix, but Without More Research and Guardrails, It’s a Costly Gamble − with Potentially Harmful Results
The underlying problem has been known for decades: Fossil-fuel vehicles and power plants, deforestation and unsustainable agricultural practices have been putting more carbon dioxide into the atmosphere than the Earth’s systems can naturally remove, and that’s heating up the planet. Geoengineering, theoretically, aims to restore that balance, either by removing excess carbon dioxide from the atmosphere or reflecting solar energy away from Earth. But changing Earth’s complex and interconnected climate system may have unintended consequences.

Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.

TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.
