  1. Amazon fire

    Wildfires could flip parts of the Amazon from a carbon sponge to a source by 2050

    Climate change and deforestation could double the area burned by fire in the southern Amazon by 2050, flipping the forest from carbon sponge to source.

  2. Lake Tabourie fire

    Here’s how climate change may make Australia’s wildfires more common

    An El Niño–like ocean-atmosphere weather pattern called the Indian Ocean dipole helped fuel extremely dry conditions in Australia.

  3. Joint Polar Satellite System-1

    Climate models agree things will get bad. Capturing just how bad is tricky

    Climate models are better than ever at simulating complex interactions between ocean, air, ice and land. But scientists still aren’t really sure what the worst-case scenario might be for Earth’s future climate.

  4. Greenland rocks

    Debate over signs of early life inspires dueling teams to go to Greenland — together

    The remote site — which may or may not contain evidence of the most ancient life on Earth — could help scientists plan how to study such signs on Mars.

  5. Australopithecus anamensis reconstruction and skull

    Science News’ favorite fossils of 2019

    Fossil discoveries reported this year included Cambrian creatures, ancient bone cancer and a peek at life’s recovery after the dinosaur die-off.

  6. youth climate activists

    Record-breaking heat amplified waves of student climate protests in 2019

    While the world experienced record-breaking heat, Greta Thunberg and other activists pushed decision makers to take climate change seriously.

  7. algal bloom

    Flooding Earth’s atmosphere with oxygen may not have needed a triggering event

    Building an oxygen-rich world doesn’t require volcanism, supercontinent breakups or the rise of land plants — just nutrient cycling, a study finds.

  8. flash flooding in Ellicott City, Md.

    Fingerprints of climate change are increasingly appearing in extreme weather

    A new report finds evidence that some of 2018’s extreme weather events were linked to human-caused climate change.

  9. Columbia glacier

    See how an Alaskan glacier has shrunk over time

    Scientists have created a time-lapse series of images of the retreat of an Alaskan glacier using NASA and U.S. Geological Survey Landsat data.

  10. penguins
    Science & Society

    ‘A Polar Affair’ delves into a centurylong cover-up of penguin sex

    In a new book, Lloyd Spencer Davis seeks to understand why an Antarctic explorer kept some of his penguin observations a secret.

  11. Origolestes lii

    An ancient critter may shed light on when mammals’ middle ear evolved

    Rare skeletons are helping to pin down the evolution of mammals’ three middle ear bones, known popularly as the hammer, anvil and stirrup.

  12. Climate protest

    Countries urgently need to ramp up emissions cuts to meet climate targets

    A new U.N. report finds that pledged emissions cuts aren’t nearly enough to limit warming to “well below” 2 degrees Celsius by 2100.
