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.

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.

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.

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.

Collapsed Bridge Helps Inform Future Flood-Resistant Designs
In 2018, an unprecedented flooding collapsed the Misasa Railroad Bridge, some nine miles inland from Japan’s western coast. Such infrastructure failures will continue to increase as weather events become more extreme. But we can learn optimal design needs from the catastrophic problem of failed structures.

Bridges Under Pressure
Can a bridge withstand an earthquake? One of the big unknowns is how far a bridge might settle from seismic shaking, especially if the shaking triggers a quicksand-like soil response called liquefaction.

How Does the U.S. Power Grid Work?
Responsible for powering the country and its economy, the U.S. energy grid has come under increasing strain due to climate change, and the threat of cyberattacks looms. The U.S. electric grid brings power to millions of homes and businesses via a vast network of transmission and distribution lines. Experts say the grid is increasingly vulnerable to extreme weather events, such as the February 2021 Texas winter storms, and cyberattacks. President Biden has proposed overhauling the grid, but his plans could face legal and political hurdles.

Researchers Simulate Defense of the Earth
Sixty-six million years ago, a giant asteroid impact on the Earth likely caused the extinction of the dinosaurs. Currently no known asteroid poses an immediate threat. But if one day a large asteroid were to be discovered on a collision course with Earth, it might have to be deflected from its trajectory to prevent catastrophic consequences.

Sea Levels Rise and Floods Intensify, So Governments Consider Managed Retreat
As climate changes, rising sea levels and disastrous flooding are becoming ever more common, and they could force billions to move during the next decades. Instead of trying to prolong the inevitable by building sea walls, importing sand to build protective dunes and berms, planting mangrove, and raising structures on stilts, some communities are already adapting: They are developing plans to move away from vulnerable areas to higher ground inland.

Announcing the Electric Resilience Toolkit
A new Electric Resilience Toolkit aims to support policymakers and stakeholders working on issues around electric sector regulation and climate resilience planning. Such planning is essential to ensure electricity infrastructure is designed and operated in a way that accounts for the impacts of climate change—impacts that are already being felt and which will only intensify in coming years.

Emerging Threats to the U.S. Financial System
In early 2021, a freewheeling, freethinking group of investors on Reddit plowed their money into GameStop, a video game retailer that several big hedge funds had bet against. The stock price shot up, some people made millions—and, to the delight of those on Reddit, the hedge funds had some very bad days. Researchers saw the GameStop story as a cautionary tale. If investors on Reddit could work together to move the markets like that, what could an adversary like China do?
