• As Atmospheric Carbon Rises, So Do Rivers, Exacerbating Flooding

    When it comes to climate change, relationships are everything. That’s a key takeaway of a new study that examines the interaction between plants, atmospheric carbon dioxide and rising water levels in the Mississippi River.

  • Projecting the Future Trade of Virtual Water

     Crops require water to grow. By importing water-intensive crops, countries essentially bring in a natural resource in the form of virtual water. Agricultural virtual water is the amount of water needed to grow a particular crop in a given region.

  • New Woodlands Can Help Reduce Flooding Risk within 15 Years

    The planting of woodlands in upland areas could play a significant role in preventing the flash flooding which has increasingly affected communities across the world in recent years.

  • Energy security The Promise of California Offshore Wind Energy

    As California aims to provide 60 percent of its energy from renewable sources by 2030 and 100 percent by 2045, a Cal Poly study provides some good news: Offshore winds along the Central Coast increase at the same time that people start using more energy — in the evening.

  • Marine Sponges Inspire Next Generation Skyscrapers, Bridges

    When we think about sponges, we tend to think of something soft and squishy. But researchers are using the glassy skeletons of marine sponges as inspiration for the next generation of stronger and taller buildings, longer bridges, and lighter spacecraft.

  • Network Resilience is Key to Surviving Compound Hazard Events

    As weather extremes such as Superstorm Sandy, which swamped New York City’s subway system in 2012, increase in frequency and intensity and as cybercriminals ramp up attacks on technologies that tie together urban infrastructure systems, networks critical to the flow of data, people, goods, and services must be made more resilient to failure

  • How Many People Will Migrate Due to Rising Sea Levels? Our Best Guesses Aren’t Good Enough

    The idea that rising seas will force millions to move, unleashing a refugee crisis like no other, has now become commonplace. It’s a narrative that the media are fond of, but that does not mean it is based on evidence. The potential scale of sea level rise is becoming clearer, but this does not necessarily translate into population movements. Everything we have learned so far suggests that decisions to migrate are far more complex than a simple flight response.

  • Making Highways, Tunnels, and Bridges More Resilient to Extreme Events

    The EU-funded RESIST project aims to provide a methodology as well as tools for risk analysis and management for critical highway structures (in the case of bridges and tunnels) that will be applicable to all extreme natural and man-made events, or cyber-attacks to the associated information systems. Its goal is to increase the resilience of seamless transport operation and protect the users and operators of the European transport infrastructure by providing them optimal information.

  • Helping Urban Communities Install Low-Cost Sensors to Reduce Flood Risks

    Floods are costly and dangerous events that impact communities across the U.S. every year. DHS S&T released a guidebook to help communities deploy and operate low-cost sensors for flood monitoring and management.

  • Up to 15 Inches of Sea-Level Rise from Ice Sheets by 2100

    A collaborative effort of more than three dozen research institutions from around the world has helped to create the most accurate prediction of how melting ice in Antarctica and Greenland will contribute to global sea-level rise.   

  • What the Wildfires Tell Us about the Shortcomings of California’s Electric Grid

    In addition to the vast destruction they have caused, the wildfires that have engulfed California in recent weeks have laid bare serious concerns about the state’s electric grid. UCLA’s expert Eric Fournier explains why the architecture of California’s grid isn’t well suited for such extreme conditions and what it would take to improve it.

  • Humans Cause 97 Percent of Home-Threatening Wildfires

    People are starting almost all the wildfires that threaten U.S. homes, according to an innovative new analysis combining housing and wildfire data. Through activities like debris burning, equipment use and arson, humans were responsible for igniting 97 percent of home-threatening wildfires. Moreover, one million homes sat within the boundaries of wildfires in the last 24 years.

  • Combatting Potential Electromagnetic Pulse (EMP) Attack

    Electromagnetic Pulse (EMP) weapons have the potential to disrupt unprotected critical infrastructure within the United States and could impact millions over large parts of the country. DHS says it continues to prepare against evolving threats against the American homeland, most recently highlighting efforts to combat an EMP attack.

  • What’s Ailing California’s Electric System?

    California made headlines for all the wrong reasons recently with widespread rolling power outages in the middle of a heat wave and a pandemic. These blackouts were not an accident—they were intentionally scheduled by the grid operator, the California Independent System Operator (CAISO), due to a shortage of resources available to keep the lights on.

  • Devastating Hurricanes Could Be Up to Five Times More Likely in the Caribbean

    Global warming is dramatically increasing the risk of extreme hurricanes in the Caribbean, but meeting more ambitious climate change goals could up to halve the likelihood of such disasters in the region, according to new research.
