  1. oil storage tanks in Pecos, Texas

    A U.S. oil-producing region is leaking twice as much methane as once thought

    Satellite measurements identify the Permian Basin, a massive U.S. oil- and gas-producing area, as a large source of leaked methane to the atmosphere.

  2. Plate tectonics illustration

    Plate tectonics may have started 400 million years earlier than we thought

    Magnetic minerals in ancient rocks suggest that plate tectonics may have been under way as early as 3.2 billion years ago.

  3. Drought

    Climate change made a southwestern U.S. drought one of the worst in 1,200 years

    Tree ring records show that the 2000–2018 drought in southwestern North America is among the most severe to strike the region in over a millennium.

  4. Hurricane Dorian

    Forecasters predict a very active 2020 Atlantic hurricane season

    Warmer ocean temperatures could fuel a very active Atlantic hurricane season, with one forecast predicting 18 named storms, including nine hurricanes.

  5. Ozone in stratosphere

    The largest Arctic ozone hole ever measured is hovering over the North Pole

    A strong polar vortex in early 2020 led to what may be a record-breaking hole in the ozone layer over the Arctic.

  6. Illustration of ancient rainforest near South Pole

    Roughly 90 million years ago, a rainforest grew near the South Pole

    A forest flourished within 1,000 kilometers of the South Pole, probably because of high atmospheric carbon dioxide levels and an ice-free Antarctica.

  7. Dineobellator notohesperus illustration

    Fossils of a new dromaeosaur date to the end of the Age of Dinosaurs

    Fossils from a new dromaeosaur recovered from New Mexico suggest these fierce predators were diversifying up to the end of the Age of Dinosaurs.

  8. Asteriornis maastrichtensis 3-D–printed skull

    ‘Wonderchicken’ is the earliest known modern bird at nearly 67 million years old

    A new fossil find, dubbed the Wonderchicken, is a common ancestor of modern ducks and chickens.

  9. small dinosaur

    This ancient dinosaur was no bigger than a hummingbird

    The skull of one of these Mesozoic Era birds — the tiniest yet known — was discovered encased in a chunk of amber originally found in Myanmar.

  10. the Orroral Valley Fire in Australia

    Australia’s wildfires have now been linked to climate change

    Australia’s devastating 2019–2020 wildfires were at least 30 percent more likely due to human-caused climate change.

  11. gas burning

    Fossil fuel use may emit 40 percent more methane than we thought

    Ice cores suggest natural seeps release less methane than was estimated, meaning industry produces nearly all of today’s geologic methane emissions.

  12. Deploying float to collect ocean data

    Climate change may be speeding up ocean circulation

    Circulation in the top 2,000 meters of the world’s oceans has increased as a result of faster winds around the globe, a study suggests.
