    ‘Tree Story’ explores what tree rings can tell us about the past

    The book "Tree Story" explains how scientists decipher tree rings to discover clues about past climates and ancient civilizations.

  2. Super-typhoon Mangkhut

    How more powerful Pacific cyclones may be fueling global warming

    Increasingly strong storms in the North Pacific may be speeding up the fast-moving Kuroshio Current — which could bring more heat to high latitudes.

  3. people at a well in Misiones, Argentina

    Up to 220 million people globally may be at risk of arsenic-contaminated water

    A new world map highlights possible hot spots of arsenic contamination in groundwater.

  4. aerial photo of a freeway in Los Angeles

    Daily global CO2 emissions dropped dramatically as COVID-19 kept people home

    Daily carbon dioxide emissions in early April were 17 percent lower than average daily emissions for 2019, thanks to government policies to restrict the spread of the coronavirus.

  5. Mauna Kea volcano

    Long-dormant volcano Mauna Kea has been quietly grumbling for decades

    Small, periodic earthquakes have happened every seven to 12 minutes for decades, but aren’t reason for alarm, a new study finds.

  6. Puerto Rico flooding

    What data do cities like Orlando need to prepare for climate migrants?

    As researchers wrestle with how to anticipate future population shifts due to climate change, possible “destination cities,” like Orlando, Fla., prepare for an influx.

  7. Michael Moore on stage

    What Michael Moore’s new film gets wrong about renewable energy

    Michael Moore’s Planet of the Humans challenges renewable energy’s ability to fight climate change, but it’s riddled with errors and old information.

  8. Sediment sample collection near Peru

    Deep-sea mining may damage underwater ecosystems for decades

    Microbe communities in the seabed off Peru still haven’t fully recovered from being disturbed by a deep-sea mining experiment 26 years ago.

  9. illustration of Spinosaurus

    Spinosaurus fossil tail suggests dinosaurs were swimmers after all

    Unique among known dinosaurs, Spinosaurus had a finlike tail, which the predator may have used to propel itself through the water.

  10. 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.

  11. 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.

  12. 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.
