• Strengthening Puerto Rico's Power Grid

    The 2017 Hurricane Maria made a direct hit on Puerto Rico in 2017, it ravaged the island’s power grid and caused the longest blackout in U.S. history. Maria left many residents without power for nearly a year. As more hurricanes threaten, Puerto Rico utilities are shoring up their defenses using the Electrical Grid Resilience and Assessment System (EGRASS) planning tool.

  • Predicting Landslides Along Wildfire Burn Scars

    A wildfire followed by an intense rainstorm is often a recipe for disaster. Without vegetation to cushion rainfall, water runoff can turn into fast-moving, highly destructive landslides. Simulations could become an early warning system for people living in high-risk areas.

  • World's Biggest Ice Sheet Could Cause Massive Sea Rise Without Action

    A new study shows that the worst effects of global warming on the East Antarctic Ice Sheet (EAIS) could be avoided. That depends upon temperatures not rising by more than 2°C above pre-industrial levels.

  • Wealthiest Homeowners Most at Risk of Wildfire Hazard

    The top 10 cent most valuable homes in the western United States are 70% more likely to be in high wildfire hazard areas than median-value properties, measured by county.

  • Planning Climate-Smart Power Systems

    Unprecedented heat waves, storms, and wildfires are pushing electrical grids in the United States to their limits. An energy scientist and a climate scientist discuss how utilities can plan for a resilient electrical grid in the face of an uncertain climate future.

  • NSF Grants to Protect Data, User privacy

    Researchers are working on two new cybersecurity projects, recently funded by the National Science Foundation, to ensure trustworthy cloud computing and increase computing privacy for marginalized and vulnerable populations.

  • Climate Change Is Making Flooding Worse: 3 Reasons the World Is Seeing More Record-Breaking Deluges and Flash Floods

    Although floods are a natural occurrence, human-caused climate change is making severe flooding events more common. I study how climate change affects hydrology and flooding. In mountainous regions, three effects of climate change in particular are creating higher flood risks: more intense precipitation, shifting snow, and rain patterns and the effects of wildfires on the landscape.

  • U.S. Senate Approves Bill Containing Texas’ “Ike Dike” Coastal Protection Project

    The U.S. Senate voted to authorize the U.S. Army Corps of Engineers to begin planning for a massive coastal barrier project in Galveston Bay meant to protect against hurricanes’ storm surge. Funding is not yet secured.

  • Tool Estimates Costs of Power Interruptions

    Berkeley Lab-led initiative helps electric companies improve grid reliability and resilience. The initiative aims to update and upgrade the Interruption Cost Estimate (ICE) Calculator – a publicly available, online tool – which estimates the economic consequences of power interruptions.

  • New Flood Maps Clarify the Risk Homeowners Face

    Flooding in urban areas cost Americans more than $106 billion between 1960 and 2016, damaging property, disrupting businesses and claiming lives in the process. Determining which areas are most likely to flood amid ever-changing land use and shifting rainfall and climate patterns can be expensive and complicated. New maps more realistically depict flood zones with less effort, lower costs.

  • The World’s Largest Experimental Earthquake Infrastructure Facility

    The National Science Foundation (NSF) promotes research investments and technology that help recognize and mitigate the impacts of natural disasters across the U.S.“The ability to test infrastructure under a full range of motion is critical for unleashing new and pioneering research that can lead to effective, economical and innovative infrastructure designs and retrofitting strategies for existing infrastructure,” said NSF director Sethuraman Panchanathan.

  • Why UK Railways Can’t Deal with Heatwaves – and What Might Help

    Like most construction materials, steel, which rails are made from, expands when air temperature increases. When this movement is restrained by the anchorage, which holds the rail and the sleeper (the rectangular supports for the rails) in place, internal stresses build up, and compression buckles or kinks the rail. Trains cannot travel over rail lines with kinks. In the US, kinks caused by the sun caused over 2,100 train derailments in the past 40 years, equivalent to around 50 derailments per year.

  • Climate Change, Land-Use Changes Increase Likelihood of Flood Events

    The German government estimates the total losses resulting from the disastrous floods in July 2021 at 32 billion euros. To improve future preparedness for such extreme events, researchers advise that risk assessments take greater account of the landscape and river courses, how they change, and how sediments are transported. In addition, projections show an increase in the spatial extent and frequency of such extreme events, as well as higher amounts of precipitation.

  • Europe Heat Wave: U.K. Records Hottest-Ever Temperature

    Western Europe continues to bake in extreme heat, with the UK recording a temperature over 40 degrees Celsius for the first time, and wildfires burning through French forests. Relief is expected later in the week.

  • Britain Isn’t Built to Withstand 40°C – Here Is Where Infrastructure Is Most Likely to Fail

    Climate change is intensifying heatwaves in the UK, an affluent country with the capacity and resources to adapt to warmer temperatures. Still, very little has been done over the past ten years to address overheating in buildings and the rising risk to critical infrastructure. The country is unprepared to handle temperatures of more than 38°C consistently for long periods, which is more common in Mediterranean countries.
