  1. a huge column of smoke reaching into the stratosphere over Australia
    Climate

    How wildfires deplete the Earth’s ozone layer

    Scientists detail the chain of chemical reactions that occur when wildfire smoke enters the stratosphere.

  2. Iceberg A68a in the Southern Ocean during July 2020
    Climate

    Here’s what happened to the Delaware-sized iceberg that broke off Antarctica

    The powerful pull of currents in the Southern Ocean probably pulled apart the largest remnant of a massive iceberg that split off Antarctica in 2017.

  3. A photo of a researchers camp on Antarctica's Thwaites Glacier.
    Climate

    Rapid melting is eroding vulnerable cracks in Thwaites Glacier’s underbelly

    Thwaites is melting slower than thought, but the worst of it is concentrated in underbelly cracks, threatening the Antarctica glacier’s stability.

    Climate

    Greenland’s frozen hinterlands are bleeding worse than we thought

    An inland swath of the Northeast Greenland Ice Stream is accelerating and thinning. It could contribute much more to sea level rise than estimated.

  5. A photo of several tents set up on in Antarctica.
    Climate

    Many Antarctic glaciers are hemorrhaging ice. This one is healing its cracks

    Scientists have explored the recesses of an Antarctic glacier that is currently stable, helping improve predictions of the continent’s fate.

  6. Human skeleton from waist down showing earliest surgery
    Life

    Here are 5 record-breaking science discoveries from 2022

    The earliest surgery, fastest supercomputer and biggest single-celled bacteria were some of this year’s top science superlatives.

  7. image of researchers crouched on the ice with snowmobiles
    Planetary Science

    Machine learning points to prime places in Antarctica to find meteorites

    Using data on how ice moves across Antarctica, researchers identified more than 600 spots where space rocks may gather on the southern continent.

  8. Satellite image of an Antarctic glacier shedding ice into Pine Island Bay
    Climate

    Ancient penguin bones reveal unprecedented shrinkage in key Antarctic glaciers

    Thwaites and Pine Island glaciers are losing ice faster than any other time in the last 5,500 years. That history is written in bones and shells.

  9. photo of Thwaites Glacier
    Climate

    Antarctica’s Thwaites Glacier ice shelf could collapse within five years

    The loss of Thwaites’ buttressing ice shelf could hasten the demise of the “Doomsday Glacier” and raise the risk of dramatic sea level rise.

  10. Computer artwork of extinct woolly mammoths (Mammuthus primigenius) in a snow-covered field. A bison stands in the distance.
    Paleontology

    Mammoths may have gone extinct much earlier than DNA suggests

    Ancient DNA in sediments may be leading paleontologists astray in attempts to figure out when woolly mammoths and woolly rhinos died out, a new study argues.

  11. Glassy debris creates the bluish tinge and radiating black stripes around an impact crater on Mars
    Planetary Science

    Asteroid impacts might have created some of Mars’ sand

    Roughly a quarter of the Red Planet’s sand is spherical bits of glass forged in violent impacts, new observations reveal.

  12. satellite images from before and after drainage of an ice-covered lake in Antarctica
    Earth

    Satellites show how a massive lake in Antarctica vanished in days

    Within six days, an Antarctic lake with twice the volume of San Diego Bay drained away, leaving a deep sinkhole filled with fractured ice.
