  1. illustration of a long-necked dinosaur leaning down to drink from a river

    How massive long-necked dinosaurs rose to rule the Jurassic herbivores

    New dinosaur fossil dates to same time as a volcanic surge, suggesting ensuing changes in plant life allowed these long-necked giants to emerge.

  2. Hurricane Harvey

    Once hurricanes make landfall, they’re lingering longer and staying stronger

    Warmer ocean waters due to human-caused climate change can help power hurricanes’ fury even after they roar ashore.

  3. ancient amphibian skull

    An ancient amphibian is the oldest known animal with a slingshot tongue

    A tiny amphibian that lived 99 million years ago waited for invertebrate prey before snatching them with a swift, shooting tongue.

  4. Ambopteryx longibrachium

    Bat-winged dinosaurs were clumsy fliers

    The two known species of bat-winged dinosaurs were a dead end when it comes to the evolution of bird flight, a new study finds.

  5. Megalodon shark illustration

    Cannibalism in the womb may have helped megalodon sharks become giants

    The ancient sea terror Otodus megalodon may have grown to at least 14 meters long thanks to a firstborn pup’s predatory behavior, some researchers say.

  6. Greenland ice sheet

    By 2100, Greenland will be losing ice at its fastest rate in 12,000 years

    The rate of loss of Greenland’s ice will soar over the next century even with greatly reduced greenhouse gas emissions.

  7. Getz Ice Shelf

    Global warming may lead to practically irreversible Antarctic melting

    Simulations suggest that even if the Paris climate goals are met, melting Antarctica ice will still cause sea levels to rise by more than 2 meters.

  8. ocean waves

    Underwater earthquakes’ sound waves reveal changes in ocean warming

    A new technique uses the echoes of earthquakes in seawater to track the impact of climate change on the oceans.

  9. Hope Diamond

    Earth’s rarest diamonds form from primordial carbon in the mantle

    Chemical analyses of the rarest diamonds suggest the planet’s carbon cycle may not go as deep as scientists thought.

  10. Nathaniel B. Palmer research ship in West Antarctica

    New maps show how warm water may reach Thwaites Glacier’s icy underbelly

    New seafloor maps around Thwaites Glacier in Antarctica reveal how deep channels could help warm ocean water melt the glacier from below.

  11. Bering Sea ice

    Bering Sea winter ice shrank to its lowest level in 5,500 years in 2018

    Peat cores that record five millennia of climate shifts in the Arctic region suggest recent ice loss is linked to rising carbon dioxide levels.

  12. Hurricane Laura

    What’s behind August 2020’s extreme weather? Climate change and bad luck

    On top of a pandemic, the United States is having an epic weather year — a combination of bad luck and a stage set by a warming climate.
