• “Viable but Narrow” Pathway to Zero Carbon Emissions by 2050: IEA

    The world has a viable pathway to building a global energy sector with net-zero emissions in 2050, but it is narrow and requires an unprecedented transformation of how energy is produced, transported and used globally, the International Energy Agency said in a landmark special report released Tuesday.

  • A Dangerous Fire Season Looms as the Drought-Stricken Western U.S. Heads for a Water Crisis

    Just about every indicator of drought is flashing red across the western U.S. after a dry winter and warm early spring. The snowpack is at less than half of normal in much of the region. Reservoirs are being drawn down, river levels are dropping and soils are drying out. It’s only May, and states are already considering water use restrictions to make the supply last longer.

  • Seeking Inclusive Strategies to Help Coastal Communities Adjust, Plan for Sea-Level Rise

    Recurring flood damage to homes and powerful storms that threaten infrastructure are realities facing many coastal North Carolina communities. However, for three predominately African-American, rural communities near the coast, NC State researchers documented additional injustices that threaten the communities’ ability to adapt to a changing climate.

  • Antarctica Remains the Wild Card for Sea-Level Rise Estimates

    Estimates show that limiting global warming to 1.5 degrees C above pre-industrial temperatures would cut projected 21st century sea-level rise from land ice in half, relative to currently pledged emissions reductions.

  • Experts Evaluate Planetary Defense Methods

    Scientists are working to develop methods to prevent asteroids from wreaking havoc on Earth. “We know that currently, the U.S. has many knowledge and capability gaps for planetary defense readiness,” says one expert.. “The work we are doing today, and the opportunity to discuss that work with the broader international community at venues like the IAA Planetary Defense Conference (PDC), is helping to close these gaps.”

  • 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.
