  1. Climate

    The list of extreme weather caused by human-driven climate change grows

    The tally of extreme weather events linked to climate change continues to grow, with new studies outlining links to more than a dozen events in 2017.

  2. Oceans

    Volcanic eruptions that depleted ocean oxygen may have set off the Great Dying

    Massive eruptions from volcanoes spewing greenhouse gases 252 million years ago may have triggered Earth’s biggest mass extinction.

  3. Climate

    Here’s how much climate change could cost the U.S.

    A report by hundreds of scientists from 13 federal agencies starkly outlines the economic impacts of climate change on the United States.

  4. Earth

    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. Paleontology

    Eggs evolved color and speckles only once — during the age of dinosaurs

    Birds’ colorful eggs were inherited from their nonavian dinosaur ancestors.

  6. Paleontology

    The first vertebrates on Earth arose in shallow coastal waters

    After appearing about 480 million years ago in coastal waters, the earliest vertebrates stayed in the shallows for another 100 million years.

  7. 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.

  8. 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.

  9. 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.

  10. 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.

  11. Climate

    Here’s what’s unusual about Hurricane Michael

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

  12. 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.
