  1. Steamboat Geyser

    Reawakened Yellowstone geyser isn’t a sign of imminent explosion

    The 2018 reactivation of Yellowstone’s Steamboat Geyser isn’t a portent of dangerous volcanic or hydrothermal eruptions, scientists say.

  2. a nearly empty city street in New York City

    What the pandemic can teach us about ways to reduce air pollution

    Data collected during COVID-19 shutdowns may help tease out the complicated chemistry that brews poor air quality.

  3. East Troublesome Fire

    Wildfires, heat waves and hurricanes broke all kinds of records in 2020

    Climate change did not take a break during the pandemic.

  4. big cloud of smoke hovering over the top of the hill tops

    Towering fire-fueled thunderclouds can spew as many aerosols as volcanic eruptions

    A massive plume of smoke lofted into the stratosphere during Australia’s fires may represent a new class of “volcanic-scale” pyrocumulonimbus clouds.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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.

  10. 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.

  11. 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.

  12. 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.
