From Wadham to GCHQ and Back: Robert Hannigan on Cybercrime, Spying and the AI Tsunami Coming Our Way
Is the much-vaunted cyber-Armageddon likely or even possible? One experts says that “‘State cyber threats do get overplayed. They can’t do everything and countries over-estimate their cyber capabilities – just as they over estimate their military capability.” The expert insists, however, that “The challenges are ‘moving very fast’, as potential attackers learn fast.”

New York’s Climate Buyout Plans Must Put Communities First: Experts
In 2022, New York State passed the Clean Water, Clean Air and Green Jobs Environmental Bond Act. Among its many objectives, the act promises to invest more than a billion dollars toward flood protection across the state — including through voluntary private property buyouts. What should a buyout program look like? Designing an equitable buyout program is more complicated than it may seem.

NOAA’s 1-in-100 Year Flooding Can Now Be Expected Every 8 Years
NOAA’s 1-in-100 year floods are supposed to occur once every 1 years – except that in parts of the United States, climate change is causing these events to occur at least once every 8-10 years. Moreover, increases in severe rainfall events are taking place in some of the most populated areas of the country – throughout the Northeast, along the Ohio River Valley, and the Texas and Louisiana Gulf Coast.

The Future of Nuclear Power in a Low-Carbon World
For decades, large gigawatt-scale nuclear reactors have provided a significant portion of electricity in the United States, but most of these reactors are at least 40 years old. As the nation moves to decarbonize the economy and transition to clean energy, there are questions how nuclear power could maintain a position in the future energy mix ― given environmental and safety concerns, as well as the high upfront capital costs associated with building reactors.

As California Attempts a “Managed Retreat,” Coastal Homeowners Sue to Stay
“Managed retreat” is a climate adaptation policy that calls for relocating and removing coastal structures rather than protecting them where they are. Experts say managed retreat is an important last-resort option for adapting to climate change, but California’s early attempts to implement the policy have provoked a backlash from homeowners and politicians.

The long view
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.
Could We Use Volcanoes to Make Electricity?
It is challenging, but tapping into the Earth’s natural heat can create a renewable, reliable and clean source of energy. As technology improves, more places around the world will turn to geothermal energy to light up people’s lives. Volcanoes are reminders of a great powerhouse deep underground that’s waiting to be harnessed.
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.”
New Gels Could Protect Buildings During Wildfires
Researchers have developed a sprayable gel that creates a shield to protect buildings from wildfire damage. It lasts longer and is more effective than existing commercial options.

U.S. Water Reservoirs Are Shrinking and Becoming Less Reliable, New Study Finds
Major water reservoirs across the continental United States are experiencing longer, more severe, and more variable periods of low storage than several decades ago, a new study reports. The problems are most severe in the western and central United States, but reservoirs in the eastern and southeastern United States are not immune.
