• The Resilience and Safety of Nuclear Power in the Face of Extreme Events

    As the prospect of extreme global events grows — from natural disasters and intensifying climate change-driven weather patterns that could affect a nuclear plant, to a rise in infectious diseases that could affect its workforce — nuclear power plants’ adaptable workforces and robust designs will be essential to staying resilient and contributing to a low carbon path to the future.

  • Functionally Graded Material Resistant to Blasts, Fire in buildings

    When a bomb goes off or fire breaks out, a building constructed or retrofitted with an engineered composite currently confined to special applications could buy the surviving occupants extra time to get out. Functionally graded material (FGM), a recently developed composite characterized by the gradual variation of material properties across its thickness, is an effective bomb-resistant material in structural uses.

  • Nobody Saw It Coming: How Scenarios Can Help Us Prepare for the Future in an Uncertain World

    The problem with planning for the future is that it is fundamentally uncertain, and predictions often fall flat when compared with reality. This gap—between the limits of what we can know about the future and the need to plan for it—has led to the development of a variety of tools for futures thinking.

  • Assessing Bridge Support Repairs After Earthquakes

    Steel-reinforced concrete columns that support many of the world’s bridges are designed to withstand earthquakes, but always require inspection and often repair once the shaking is over. Engineers simulate restoration strategies for reinforced concrete columns.

  • Repeated Exposure to Major Disasters Has Long-Term Mental Health Impacts

    New study found Houston residents who experienced two or more hazardous events in the past five years had a reduction in mental health scores.

  • New Federal Wildfire Plan Is Ambitious – but the Forest Service Needs More Money and People to Fight the Growing Risks

    As foresters who have been working on wildfire and forest restoration issues in the Sierra Nevada for over a quarter of a century, the main lesson we gather from how wildfires have burned is that fuels reduction and forest restoration projects are our best tools for mitigating wildfire impacts amid a changing climate, and not nearly enough of them are being done.

  • A Small City’s Hurricane Recovery Could Help Other Communities Bounce Back

    In September 2018, a North Carolina city’s long road to recovery from Hurricane Matthew two years earlier became even longer. Lumberton, a small but diverse city of 21,000 people, 96 kilometers (60 miles) inland from the coast, unfortunately found itself in Hurricane Florence’s sights.

  • ShakeAlert Earthquake Warnings Can Give People Time to Protect Themselves – But So Far, Few Have Actually Done So

    The ShakeAlert system is a remarkable technology, years in the making. It has the potential to save tens of thousands of lives in areas where high-magnitude earthquakes occur by providing a few seconds’ warning – enough time for people to take basic safety precautions. Marvelous as it is, though, ShakeAlert saves lives only if people understand what to do when they receive such an alert – and do it.

  • Simulations Can Improve Avalanche Forecasting

    Currently, avalanche forecasts in Canada are made by experienced professionals who rely on data from local weather stations and on-the-ground observations from ski and backcountry ski operators, avalanche control workers for transportation and industry, and volunteers who manually test the snowpack. But simulated snow cover models developed by a team of researchers are able detect and track weak layers of snow and identify avalanche hazard in a completely different way.

  • 2021 Was U.S. 4th-Warmest Year on Record, Fueled By a Record-Warm December

    The year 2021 was marked by extremes across the U.S., including exceptional warmth, devastating severe weather and the second-highest number of billion-dollar weather and climate disasters on record. The U.S. was struck with 20 separate billion-dollar disasters in 2021.

  • Weather Disasters in U.S. Dominate Natural Disaster Losses in 2021

    In 2021, natural disasters caused overall losses of $280bn, of which roughly $120bn were insured. Alongside 2005 and 2011, the year 2021 proved to be the second-costliest ever for the insurance sector (record year 2017: $146bn, inflation-adjusted). Overall losses from natural disasters were the fourth-highest to date (record year 2011: $355bn). Hurricane Ida was the year’s costliest natural disaster, with overall losses of $65bn (insured losses of $36bn). In Europe, flash floods after extreme rainfall caused losses of $54bn (€46bn) – the costliest natural disaster on record in Germany. Many of the weather catastrophes fit in with the expected consequences of climate change, making greater loss preparedness and  climate protection a matter of urgency.

  • Leveraging Social Media During a Disaster

    During a disaster, many people turn to social media seeking information. But communicating during disasters is challenging, especially using an interactive environment like social media where misinformation can spread easily.

  • Enhancing Earthquake Resilience by Updating Steel Building Standard

    Since the mid-1990s, a type of steel column that commonly features slender cross-sectional elements has become more prevalent in buildings along the West Coast of the United States and in other seismically active regions. Although these columns have complied with modern design standards, expert say that our understanding of how they would perform during an earthquake has been limited by a lack of full-scale testing.

  • Cities Boosted Rain, Sent Storms to the Suburbs During Europe’s Deadly Summer Floods

    When it comes to extreme weather, climate change usually gets all the attention. But according to a new study, the unique effects of cities – which can intensify storms and influence where rain falls – need to be accounted for as well.

  • Compound-Flood Modeling Tools Hel Build Community Climate Resilience

    In 2021, extreme flooding from rain affected residents across the United States, causing property damage and loss of life. These extreme weather events are becoming all too common. In fact, a recent United Nations report—Climate Change 2021—found that heavy rain events are likely to become more intense and frequent, resulting in an increase in severe flooding events around the globe.
