• Earthquake Early Warnings Launched in Washington

    When the Big One hits, the first thing Washington residents notice may not be the ground shaking, but their phone issuing a warning. This week, the ShakeAlert early warning system was activated in Washington state, and it will send earthquake early warnings throughout the state.

  • Improving Grid Reliability in the Face of Extreme Events

    The nation’s power grid remains vulnerable to disruption from extreme events including wildfires, severe storms, and cyberattacks. Variable generation resources and load volatility also present operational challenges to grid stability. To mitigate disruptions before they snowball, grid planners and operators must be able to see these events coming and understand their potential impacts on grid reliability.

  • The New U.S. Climate Normals Are Here

    Every 10 years, NOAA releases an analysis of U.S. weather of the past three decades that calculates average values for temperature, rainfall and other conditions. That time has come again. Known as the U.S. Climate Normals, these 30-year averages — now spanning 1991-2020 — represent the new “normals” of our changing climate.

  • Entire U.S. West Coast Now Has Access to ShakeAlert Earthquake Early Warning

    After fifteen years of planning and development, the ShakeAlert earthquake early warning system is now available to more than fifty million people in California, Oregon and Washington, the most earthquake-prone region in the conterminous U.S.

  • Mapping Local Earthquake Risks from Eagle Ford Fracking

    Scientists simulated the local risk of damaging or nuisance-level shaking caused by hydraulic fracturing across the Eagle Ford shale formation in Texas. The results could inform a new approach to managing human-caused earthquakes.

  • Antarctic Ice-Sheet Melting to Lift Sea Level Higher Than Thought: Study

    Global sea-level rise associated with the possible collapse of the West Antarctic Ice Sheet has been significantly underestimated in previous studies, meaning the sea level in a warming world will be greater than anticipated, according to a new study. New calculations show the rise due to warming would be 30 percent above forecasts.

  • Homes in Floodplains Are Overvalued by Nearly $44 Billion

    Analysis of sales data and flood risk data over two decades indicates that housing markets fail to fully account for information about flood risk. The findings suggest that policies to improve risk communication could influence market outcomes.

  • California's Wildfire Season Has Lengthened, and Its Peak Is Now Earlier in the Year

    California’s wildfire problem, fueled by a concurrence of climate change and a heightened risk of human-caused ignitions in once uninhabited areas, has been getting worse with each passing year of the 21st century.Researchers have found that the annual burn season has lengthened in the past two decades and that the yearly peak has shifted from August to July.

  • New Tool Could Guide Floodwater Management and Combat Ongoing Drought

    Using a new computer framework, scientists are able to project future floodwaters under a changing climate. The approach could help California water managers plan for and redirect floodwaters toward groundwater aquifers, alleviating both flood and drought risks.

  • Lessons from Past Emergencies Could Improve the Pandemic Response

    The lack of accountability, poor communication and insufficient planning plaguing the government’s response to the COVID-19 pandemic — especially in its early months — have roots in how the nation responded to 9/11, Hurricane Katrina and the H1N1 swine flu, a new study finds.

  • Texas House Targets Power Grid Flaw that Cut Electricity to Natural Gas Facilities and Worsened February Blackouts

    The lower chamber gave initial approval Monday to a series of bill responding to this year’s catastrophic power outages during a deadly winter storm.

  • Combining News Media and AI to Rapidly Identify Flooded Buildings

    Artificial intelligence (AI) has sped up the process of detecting flooded buildings immediately after a large-scale flood, allowing emergency personnel to direct their efforts efficiently. Now, researchers have created a machine learning (ML) model that uses news media photos to identify flooded buildings accurately within 24 hours of the disaster.

  • Negative Emissions, Positive Economy

    The long-term goals of the Paris Agreement — keeping global warming well below 2 degrees Celsius and ideally 1.5 C in order to avert the worst impacts of climate change — may not be achievable by greenhouse gas emissions-reduction measures alone. Most scenarios for meeting these targets also require the deployment of negative emissions technologies (NETs) that remove carbon dioxide (CO2) from the atmosphere. Bioenergy with carbon capture and storage could help stabilize the climate without breaking the bank.

  • How Do We Know Whether an Asteroid Headed Our Way Is Dangerous?

    There are a lot of things that pose a threat to our planet – climate change, natural disasters, and solar flares, for example. But one threat in particular often captures public imagination, finding itself popularized in books and films and regularly generating alarming headlines: asteroids.

  • The U.S. Water and Wastewater Crisis – How Many Wake-up Calls Are Enough?

    In February, much of Texas plunged into darkness when the state’s electricity grid failed due to extreme cold weather conditions. What started as a foreseeable blackout quickly became a life-threatening calamity. “This catastrophe illustrates what happens when aging and inadequate infrastructure is hit by extreme rain or snow—an increasingly regular occurrence due to climate change,” Lucía Falcón Palomar, Obinna Maduka, and JoAnn Kamuf Ward write. “And, the matter extends well beyond Texas. It is easy to forget that, within U.S. borders, communities have long endured the conditions seen in Texas in February.”
