  1. Earth

    Another danger looms after the LA fires: Devastating debris flows

    As wildfires burn the landscape, they prime slopes for debris flows: powerful torrents of rock, mud and water that sweep downhill with deadly momentum.

  2. Climate

    Unearthed ice may be the Arctic’s oldest buried glacier remnant

    Thanks to climate change, thawing permafrost in the Canadian Arctic has revealed the buried remnant of a glacier that’s 770,000 years old.

  3. Environment

    A podcast challenges us to reassess our relationship with wildfires

    United by Fire lays out key insights from the two largest blazes in Colorado history, the Cameron Peak and East Troublesome fires of 2020.

  4. Climate

    California wildfire season should be over. So why is L.A. burning?

    In some parts of California, fire season is now year-round due to rising heat and little rain. High winds and dry conditions are fueling L.A.’s infernos.

  5. Planetary Science

    NASA’s Perseverance rover found a new potential setting for Martian life

    Now atop Jezero Crater, the robotic explorer found quartz indicative of habitable environments and possibly the oldest rocks yet seen in the solar system.

  6. Earth

    Earth’s inner core may be changing shape

    Earthquake data suggest that all or small patches of the inner core's surface may be swelling and contracting.

  7. Climate

    Climate change made 2024 the hottest year on record. The heat was deadly

    Heat waves fueled by climate change killed scores of people and upended daily life. Here are some of those stories.

  8. Climate

    From electric cars to wildfires, how Trump may affect climate actions

    Trump’s first term, campaign pledges and nominees point to how efforts to address climate change and environmental issues may fare.

  9. Climate

    Climate change has amped up hurricane wind speeds by 29 kph on average

    Every single Atlantic hurricane in 2024 had wind speeds supercharged by warming seas. One even jumped two categories of intensity.

  10. Oceans

    The world’s largest coral was discovered in the South Pacific

    The behemoth coral, discovered in October in the Solomon Islands, is longer than a blue whale and older than the United States.

  11. Environment

    Fire-prone neighborhoods on the fringes of nature are rapidly expanding

    The transition zone where unoccupied wildlands meet developed areas increased globally by about 35 percent from 2000 to 2020.

  12. Tech

    Feather-inspired airplane flaps could boost flight performance

    Rows of flaps inspired by bird wing feathers improve airfoil performance by boosting lift, reducing drag and mitigating stall.
