The World’s Largest Experimental Earthquake Infrastructure Facility
The National Science Foundation (NSF) promotes research investments and technology that help recognize and mitigate the impacts of natural disasters across the U.S.“The ability to test infrastructure under a full range of motion is critical for unleashing new and pioneering research that can lead to effective, economical and innovative infrastructure designs and retrofitting strategies for existing infrastructure,” said NSF director Sethuraman Panchanathan.

Amid Climate Change and Conflict, More Resilient Food Systems a Must: Report
Increased demand for water will be the No. 1 threat to food security in the next 20 years, followed closely by heat waves, droughts, income inequality and political instability.

Why UK Railways Can’t Deal with Heatwaves – and What Might Help
Like most construction materials, steel, which rails are made from, expands when air temperature increases. When this movement is restrained by the anchorage, which holds the rail and the sleeper (the rectangular supports for the rails) in place, internal stresses build up, and compression buckles or kinks the rail. Trains cannot travel over rail lines with kinks. In the US, kinks caused by the sun caused over 2,100 train derailments in the past 40 years, equivalent to around 50 derailments per year.

Climate Change, Land-Use Changes Increase Likelihood of Flood Events
The German government estimates the total losses resulting from the disastrous floods in July 2021 at 32 billion euros. To improve future preparedness for such extreme events, researchers advise that risk assessments take greater account of the landscape and river courses, how they change, and how sediments are transported. In addition, projections show an increase in the spatial extent and frequency of such extreme events, as well as higher amounts of precipitation.

Generating Power at the Point Where Seawater, River Water Meet
It is theoretically possible to generate electricity through the movement of water in locations where seawater and river water meet. This type of technology is called osmotic power generation or blue energy. Though prototypes of this technology have been built, research is still underway to prove that this technology is scalable and reliable.

Europe Heat Wave: U.K. Records Hottest-Ever Temperature
Western Europe continues to bake in extreme heat, with the UK recording a temperature over 40 degrees Celsius for the first time, and wildfires burning through French forests. Relief is expected later in the week.

Britain Isn’t Built to Withstand 40°C – Here Is Where Infrastructure Is Most Likely to Fail
Climate change is intensifying heatwaves in the UK, an affluent country with the capacity and resources to adapt to warmer temperatures. Still, very little has been done over the past ten years to address overheating in buildings and the rising risk to critical infrastructure. The country is unprepared to handle temperatures of more than 38°C consistently for long periods, which is more common in Mediterranean countries.

Warning System for Dangerous Heavy Rain and Flash Floods
In recent years, there have been repeated flash floods in Germany, some with devastating effects, which have been triggered by localized heavy rainfall. New project aims to provide prototypical warnings at different spatial scales, from the whole of Germany to individual federal states and down to the municipal level.

Water Resources to Become Less Predictable with Climate Change
Many regions of Earth rely on the accumulation of snow during the winter and subsequent melting in the spring and summer for regulating runoff and streamflow. Water resources will fluctuate increasingly and become more and more difficult to predict in snow-dominated regions across the Northern Hemisphere.

U.S. Dominated by Remarkable Heat, Dryness
June kicked off a very warm and dry start to meteorological summer for the U.S. The U.S. struck with 9 separate billion-dollar disasters so far this year. The average June temperature across the contiguous U.S. was 70.7 degrees F — 2.2 degrees above average.

Rare Earths in Australia Must Be About More Than Mining
REEs are a group of 17 metals—15 elements from the lanthanide series and two chemically similar elements, scandium and yttrium. Each has unique properties vital for a range of commercial and defense technologies, including batteries, high-powered magnets and electronic equipment. China’s rare-earth production exceeds that of the world’s second-largest producer, the U.S., by more than 100,000 tons per year. The U.S. still relies on China for most rare-earth imports. In some cases, like heavy REE processing, China has 100 percent control of the market.

Protecting the Coastline
Barrier islands protect the coastline from storms, storm surge, waves and flooding. They can act as a buffer between the ocean and beachfront property. But as sea level rises, barrier islands retreat, or move closer toward the shore, which diminishes the buffer and protection. Oceanographers develop new model to better predict barrier island retreat.

Hurricane-Resilient Wind Turbines -- Inspired by Palm Trees
Today’s offshore wind turbines can tower more than 490 feet above ground, their spinning blades churning out up to 8 megawatts (MW) each—about enough to power 4,000 homes in the U.S. But with their increasing size comes challenges. To make those turbines more hurricane-resilient, scientists are taking a cue from nature.

Climate Models May Underestimate Future Floods
Climate models may be significantly underestimating how extreme precipitation will become in response to a rise in greenhouse gases in the atmosphere, a new study finds. It all comes down to raindrop physics, says one researcher: Even a slight change in the percentage of each falling raindrop to reach the Earth’s surface can mean the difference between a climate of light drizzles and one that creates unprecedented deluges.
