  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. smoke stacks

    50 years ago, scientists puzzled over a slight global cooling

    Five decades ago, scientists were puzzled over a slight dip in global temperatures. Today we know it was just a blip, and that Earth’s climate is warming thanks to industrial activity over the last century.

  7. Climate

    The loss of ‘eternal ice’ threatens Mongolian reindeer herders’ way of life

    Mongolian reindeer herders help scientists piece together the loss of the region’s vital “eternal ice” patches.

  8. landfill

    California landfills are belching high levels of climate-warming methane

    Airborne remote sensing spots the Golden State’s biggest emitters of the potent greenhouse gas from the sky.

  9. Monsoon season in China

    Geology, not CO2, controlled monsoon intensity in Asia’s ancient past

    For millions of years, shifting geologic plates — not carbon dioxide levels —held the most sway over the intensity of Asia’s seasonal winds and rains.

  10. Earth

    Powerful storms may be causing offshore ‘stormquakes’

    A perfect-storm mixture of hurricane, ocean and seafloor topography can create distinct seismic signals called “stormquakes.”

  11. Diplodocus dino head

    Big dinosaurs kept cool thanks to blood vessel clusters in their heads

    Giant dinosaurs evolved several strategies for cooling their blood and avoiding heatstroke.

  12. Mumbai aerial

    In a climate crisis, is geoengineering worth the risks?

    Some scientists say the world needs to reconsider some human-made ideas to cool the climate as dire warnings about the looming crisis ramp up.
