• What Is Hurricane Storm Surge, and Why Can It Be So Catastrophic?

    By Anthony C. Didlake Jr.

    As a hurricane reaches the coast, it pushes a huge volume of ocean water ashore. This is what we call storm surge. Of all the hazards that hurricanes bring, storm surge is the greatest threat to life and property along the coast.

  • Hundreds of Hospitals on Atlantic and Gulf Coasts at Risk of Flooding from Hurricanes

    Researchers identified 682 acute care hospitals in 78 metropolitan statistical areas located within 10 miles of the Atlantic and Gulf Coasts of the United States, covering a population just under 85 million people, or about 1 in 4 Americans. They found that 25 of the 78 metro areas studied have half or more of their hospitals at risk of flooding from a Category 2 storm.

  • Champlain Towers South Investigation Completes Site Testing

    Members of the National Construction Safety Team (NCST) completed testing at the former site of the Champlain Towers South building in Surfside, Florida, collecting data to help improve computer models that will be used to evaluate potential causes of the June 2021 collapse.

  • 3 Reasons Hurricane Ian Poses a Major Flooding Hazard for Florida

    Hurricane Ian has now been upgraded to Category 4, with winds just under 155 mph. But the scale doesn’t take water risk into account, and flooding and storm surge are both major risks from Ian. Here are three reasons Florida is facing a high risk of water hazards this week.

  • What Killed Dinosaurs and Other Life on Earth?

    By Harini Barath

    What caused the demise of the mighty dinosaurs at the end of the Cretaceous Period 66 million years ago? Some scientists argue that comets or asteroids that crashed into Earth were the most likely agents of mass destruction, while others point fingers at large volcanic eruptions.

  • Can We Really Deflect an Asteroid by Crashing into It? Nobody Knows, but We Are Excited to Try

    By Stefania Soldini

    Nasa’s Double Asteroid Redirection Test (Dart) spacecraft is designed to be a one hit wonder. It will end its days by crashing into an asteroid at 24,000 kilometers per hour on 26 September. Launched from Earth in November 2021, Dart is about the size of a bus and was created to test and prove our ability to defend the Earth from a dangerous asteroid.

  • Burying Short Sections of Power Lines Could Drastically Reduce Hurricanes' Impact on Coastal Residents

    As Earth warms, people living near the coasts not only face a higher risk of major hurricanes but are also more likely to experience heat waves while grappling with widespread power outages. Strategically burying just 5% of power lines — specifically those near main distribution points — would almost halve the number of affected residents.

  • Puerto Rico’s Vulnerability to Hurricanes Is Magnified by Weak Government and Bureaucratic Roadblocks

    By Carlos A. Suárez Carrasquillo and Fernando Tormos-Aponte

    Hurricane Maria caused extensive damage to Puerto Rico’s power grid in 2017 that left many residents without electricity for months. Rebuilding it has been hampered by technical, political and financial challenges. Now Hurricane Fiona has, again, exposed the sorry state of Puerto power grid.

  • Removing One Dam after Another: Water in the West

    Many of the cities of the American southwest would not exist were it not for dams. Dams come with a cost, but removing them without offering alternatives is a folly, Edward Ring writes. If the proponents of dam removal would simultaneously support practical new infrastructure solutions, then rewilding America’s rivers could happen without impoverishing the farms and cities that depend on water,” Ring writes. “There is naïveté, and also nihilism, in fighting to remove the building blocks of civilization without facing the realities of energy and water economics.”

  • Rapid Land Sinking Leaves Cities Vulnerable to Rising Seas

    Sea levels are rising as Earth’s ice sheets melt and as warming sea water expands, but many densely populated coastal cities around the world are more vulnerable to sea level rise because large amounts of their land are sinking. They suggest that an increase in industrial processes such as the extraction of groundwater, oil, and gas, as well as the rapid construction of buildings and other urban infrastructure may be contributing to this vulnerability.

  • Cracking the Secrets to Earthquake Safety, One Shake Simulation at a Time

    A new experimental capability, designed to replicate realistic earthquakes in the laboratory, paired with the world’s fastest supercomputers, will help lead to resilient buildings and infrastructure across the U.S.

  • New System Could Provide Early Warning of Whakaari Eruption Risk

    Kiwi volcanologists and engineers have finished testing an automated system that provides a warning when an eruption on Whakaari (White Island) becomes more likely.

  • Rising Seas Threaten Tax Bases as Private Property Falls Below Tidelines

    New analysis from Climate Central quantifies the risk of sea level rise to the tax bases of hundreds of coastal counties across 24 states and Washington, D.C. as more land falls beneath the tideline. More than 48,000 properties are projected to be entirely below their states’ tidal boundary levels by 2050, with roughly 64,000 buildings at least partially below the high tide line. By 2100 more than one million properties with a combined assessed value exceeding $108 billion are projected to be at least partly submerged at high tide.

  • Increasing Impacts of Floods and Droughts Worldwide

    Risk management has reduced the vulnerability to floods and droughts around the world, but their impact is still increasing worldwide.

  • “Prediction Markets” Could Improve Climate Risk Policies and Investment Decisions

    A market-led approach could be key to guiding policy, research and business decisions about future climate risks, a new study outlines. The paper details how expert ‘prediction markets’ could improve the climate-risk forecasts that guide key business and regulatory decisions.
