    A massive crater hides beneath Greenland’s ice

    The discovery of a vast crater in Greenland suggests that a 1-kilometer-wide asteroid hit the Earth between 2.6 million and 11,700 years ago.

  5. Climate

    Hurricane Willa breaks an eastern and central Pacific storm season record

    The combined might of eastern and central Pacific hurricanes produced a record-breaking year of storm energy.

  6. Paleontology

    T. rex pulverized bones with an incredible amount of force

    Tyrannosaurus rex’s powerful bite and remarkably strong teeth helped the dinosaur crush bones.

  7. Paleontology

    In a first, scientists spot what may be lungs in an ancient bird fossil

    Possible traces of lungs preserved with a 120-million-year-old bird fossil could represent a respiratory system similar to that of modern birds.

  8. Earth

    These ancient mounds may not be the earliest fossils on Earth after all

    A new analysis suggests that tectonics, not microbes, formed cone-shaped structures in 3.7-billion-year-old rock.

  9. Climate

    Here’s what’s unusual about Hurricane Michael

    Warm Gulf waters were the engine behind Hurricane Michael’s quick intensification.

  10. Climate

    Limiting global warming to 1.5 degrees versus 2 has big benefits, the IPCC says

    A new report from the Intergovernmental Panel on Climate Change compares the impact of warming targets on extreme weather, sea level rise and habitat loss.

  11. Climate

    How wind power could contribute to a warming climate

    If the United States had enough wind turbines to generate all of its power, they would warm the country by 0.24 degrees Celsius on average.

  12. Climate

    Warm tropical Atlantic waters juiced the 2017 hurricane season
