• The Cost of Rising Temperatures

    From crop damage to cooling failures at cloud-based data centers, climate change affects a wide variety of economic sectors. The study found that economies are sensitive to persistent temperature shocks over at least a 10-year time frame.

  • Puerto Rico: A U.S. Territory in Crisis

    The Caribbean island, which shares a close yet fraught relationship with the rest of the United States, faces a multilayered economic and social crisis rooted in long-standing policy and compounded by natural disasters, the COVID-19 pandemic, migration, and government mismanagement.

  • Barrier Islands Are Natural Coast Guards That Absorb Impacts from Hurricanes and Storms

    When hurricanes and storms make landfall, barrier islands absorb much of their force, reducing wave energy and protecting inland areas. Islands that have been preserved in their natural state can move with storms, shifting their shapes over time. But many human activities, such as turning these islands into tourist attractions –for example, Florida’s Sanibel Island and South Carolina’s Pawleys Island — interfere with these natural movements, making the islands more vulnerable.

  • A New Way to Predict Droughts

    Scientists looking at the meteorological impacts of climate change have typically looked at increases in severe weather and hurricanes. Now, they are studying another consequence of global warming that will have significant economic ramifications: drought. And advanced computing gives new window into “flash droughts.”

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

    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?

    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

    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

    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.
