World has 12 years to limit catastrophic impacts of climate change
Leading climate scientists warn that there is only a dozen years for actions to be taken to limit global warming to a maximum of 1.5C. Beyond the threshold of 1.5C warming above pre-industrial era, even half a degree of additional warming will significantly worsen the risks of drought, floods, extreme heat, and poverty for hundreds of millions of people.

Protecting the power grid from cyberattacks
As the national power grid becomes increasingly dependent on computers and data sharing—providing significant benefits for utilities, customers, and communities—it has also become more vulnerable to both physical and cyber threats. While evolving standards with strict enforcement help reduce risks, efforts focused on response and recovery capabilities are just as critical––as is research aimed at creating a well-defended next generation smart grid.

U.S. carbon-capture network could double global CO2 headed underground
With the right public infrastructure investment, the United States could as much as double the amount of carbon dioxide emissions currently captured and stored worldwide within the next six years, according to researchers.

Why it’s unwise for the U.K. to boast about its cyberattack capability
The U.K. government is very publicly investing more money in its ability to conduct cyberattacks and, at the same time, it is becoming increasingly open in talking about the attacks it has conducted in the past – and those it might conduct in future. There are risks involved in publicly signaling the imminence of cyber and other attacks, especially against capable adversaries with a demonstrable appetite for taking risks and a cavalier attitude about collateral damage. The U.K. needs to think more carefully about how it integrates cyber operations, and communication about them, into its wider approach – not only towards Russia but across the whole spectrum of national security operations.

Economic benefit of NIST’s encryption standard at least $250 billion
NIST has released a study that estimates a $250 billion economic impact from the development of its Advanced Encryption Standard (AES) over the past twenty years. AES is a cryptographic algorithm used to encrypt and decrypt electronic information. It was approved for use by the federal government in November 2001 and has since been widely adopted by private industry. Today, AES protects everything from classified data and bank transactions to online shopping and social media apps.

U.S. prepared to strike in cyberspace
The United States is prepared to go on the offensive in cyberspace to ensure adversaries know there is a price to pay for hacks, network intrusions and other types of attacks. President Donald Trump signed a new National Cyber Strategy on Thursday, calling for a more aggressive response to the growing online threat posed by other countries, terrorist groups and criminal organizations.

A bridge over the Strait of Gibraltar? New bridge forms span farther
A bridge’s span is the distance of suspended roadway between towers, with the current world record standing at just under 2km. Newly identified bridge forms could enable significantly longer bridge spans to be achieved in the future, potentially making a crossing over the Strait of Gibraltar, from the Iberian Peninsula to Morocco, feasible.

Climate change: we need to start moving people away from some coastal areas, warns scientist
Climate change has forced a paradigm shift in the way coastal flooding and erosion risks are managed. In areas of lower risk, adaptation plans are being devised, often with provisions to make properties and infrastructure more resilient. Adaptation may involve requiring raised foundations in flood-prone areas or the installation of mitigating measures, such as sustainable drainage systems. Building codes may also be established to make structures more disaster-proof and to control the types of constructions within risk zones. But such adaptation options are often of limited use or unsuitable for high-risk areas. In such areas relocation is the only safe climate-proof response.

32 dead, 500,000 homes without power, Wilmington virtually cut off
Emergency crews have been busy Monday and today in many cities across the Carolinas as both residents and the authorities were trying to cope with the aftermath of a record rainfall. The water damaged tens of thousands of homes, and floodwaters may not recede for days. Even as the remnants of Hurricane Florence pulled away, it was clear that the turmoil had only begun.

Hurricanes can cause enormous damage inland, but emergency plans focus on coasts
Coastal residents also prepare for major storms by building homes elevated above anticipated high water levels, in order to minimize damage and qualify for flood insurance. And building codes commonly call for reinforced construction to endure high wind speeds. All of these sensible and essential preparations focus on wind and storm surge in coastal zones. Today, however, risk from hurricanes is extending inland. Some of the worst damage from Eastern Seaboard hurricanes in the past several decades has come from inland flooding along rivers after storms move ashore.

When is a sea wall a good idea?
Recent hurricanes like Maria and Sandy have brought crippling winds, torrential rains, and flooding to vulnerable coastal regions, in some cases killing thousands of people. Sea walls and other barriers are often suggested as a way of protecting these low-lying coastal communities, but how large should such a wall be, and where is the most effective place to build it? Environmental scientists and researchers is trying to answer these questions and more, to help curb the devastation from future hurricanes.

Keeping buildings functioning after natural disasters
After an earthquake, hurricane, tornado or other natural hazard, it’s considered a win if no one gets hurt and buildings stay standing. But an even bigger victory is possible: keeping those structures operational. This outcome could become more likely with improved standards and codes for the construction of residential and commercial buildings.

Control system simulator helps operators to fight hackers
A simulator that comes complete with a virtual explosion could help the operators of chemical processing plants – and other industrial facilities – learn to detect attacks by hackers bent on causing mayhem. The simulator will also help students and researchers understand better the security issues of industrial control systems.

Using Artificial Intelligence to locate risky dams
In the U.S., 15,498 of the more than 88,000 dams in the country are categorized as having high hazard potential—meaning that if they fail, they could kill people. As of 2015, some 2,000 of these high hazard dams are in need of repair. With a hefty price tag estimated at around $20 billion, those repairs aren’t going to happen overnight.
