  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. Furnace Creek

    Death Valley hits 130° F, the hottest recorded temperature on Earth since 1931

    Amid a heat wave in the western United States, California’s Death Valley is back in the record books with the third hottest temperature ever recorded.

  10. a hammerhead shark swimming

    Species may swim thousands of kilometers to escape ocean heat waves

    A new analysis of ocean heat waves shows latitude matters when it comes to how far fish and other sea species must go to find cooler waters.

  11. emperor penguins

    Penguin poop spotted from space ups the tally of emperor penguin colonies

    High-res satellite images reveal eight new breeding sites for the world’s largest penguins on Antarctica, including the first reported ones offshore.

  12. microscope image of ancient microbes

    These ancient seafloor microbes woke up after over 100 million years

    Scientists discover that microbes that had lain dormant in the seafloor for millions of years can revive and multiply.
