    Oceans

    The Southern Ocean is still swallowing large amounts of humans’ carbon dioxide emissions

    A 2018 study suggested the ocean surrounding Antarctica might be taking up less CO₂ than thought, but new data suggest it is still a carbon sink.

  2. illustration of a new species of ankylosaur with a sunset in the background
    Paleontology

    This dinosaur had a weapon shaped like an Aztec war club on its tail

    The flat and spiky tail club of a newly discovered ankylosaur was unique, even for this often weirdly armored group of dinosaurs.

    How climate change may shape the world in the centuries to come

    Climate projections need to be pushed long past the established benchmark of 2100, researchers argue.

  4. a slice of diamond with tiny gray blobs of a newfound mineral called davemaoite
    Earth

    A mineral found in a diamond’s flaws contains the source of some of Earth’s heat

    A mineral theorized to exist in the mantle was found hiding in a diamond. Dubbed davemaoite, it could explain where some of Earth’s heat comes from.

    Climate

    Earth will warm 2.7 degrees Celsius based on current pledges to cut emissions

    The world still lags on its commitments to lower greenhouse gas emissions and forestall the worst effects of global warming, a new U.N. report shows.

    Climate

    2020 babies may suffer up to seven times as many extreme heat waves as 1960s kids

    Children born in 2020 will bear a much heavier burden from climate change during their lifetimes than those born in 1960, a new analysis finds.

  10. Pastoruri Glacier in the Peruvian Andes
