• Curbing Earthquakes-Induced Economic Losses to Power Plants

    Researchers have shown that during high seismic activity, the structural integrity of bushing systems can be better maintained by reinforcing their bases with steel stiffeners. Also, by using probability-based loss assessment studies, they found that the economic burden due to damage to bushing systems from earthquakes is up to 10 times lower for steel-reinforced transformer bushing systems compared to other bushing configurations.

  • 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.

  • 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.

  • 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.

  • Sea Level Rise Matches Worst-Case Scenario

    Ice sheets in Greenland and Antarctica whose melting rates are rapidly increasing have raised the global sea level by 1.8cm since the 1990s, and are matching worst-case climate warming scenarios. “The melting is overtaking the climate models we use to guide us, and we are in danger of being unprepared for the risks posed by sea level rise,” says one expert.

  • U.S. Flood Strategy Shifts to ‘Unavoidable’ Relocation of Entire Neighborhoods

    For years, even as seas rose and flooding worsened nationwide, policymakers stuck to the belief that relocating entire communities away from vulnerable areas was simply too extreme to consider — an attack on Americans’ love of home and private property as well as a costly use of taxpayer dollars. Christopher Flavelle writes that now, however, that is rapidly changing amid acceptance that rebuilding over and over after successive floods makes little sense. Using tax dollars to move whole communities out of flood zones is swiftly becoming policy, marking a new and more disruptive phase of climate change.
