All Stories by Carolyn Gramling

  1. New York City's Times Square empty due to COVID-19

    COVID-19 lockdowns dramatically reduced seismic noise from humans

    Human-caused seismic activity was reduced by as much as 50 percent around the globe during lockdowns as a result of the coronavirus pandemic.

  2. Illustration of what Microraptor looked like

    This dinosaur may have shed its feathers like modern songbirds

    One of the earliest flying dinosaurs, the four-winged Microraptor, may have molted just a bit at a time so that it could fly year-round.

  3. Oil spill in Norilsk, Russia

    Climate change made Siberia’s heat wave at least 600 times more likely

    Siberia’s six-month heat wave during the first half of 2020 would not have happened without human-caused climate change, researchers find.

  4. huge pile of discarded keyboards, computers and more

    Earth’s annual e-waste could grow to 75 million metric tons by 2030

    Unwanted electronic waste is piling up rapidly around the globe, while collection and recycling efforts are failing to keep pace, a new report shows.

  5. Yamal region of Siberia

    4 ways to put the 100-degree Arctic heat record in context

    June’s record heat in Siberia is part of a much bigger picture of dramatic climate change in the Arctic.

  6. lightning bolt

    Two lightning megaflashes shattered distance and duration records

    Satellite data show that the two extreme bolts, both appearing over South America, more than doubled the previous records.

  7. Siberian town of Verkhoyansk

    A Siberian town hit 100 degrees, setting a new record for the Arctic Circle

    Verkhoyansk’s high temperature, which has yet to be confirmed, follows a six-month period of record heat in the region.

  8. seismograph image

    Machine learning helped demystify a California earthquake swarm

    Computer algorithms helped scientists find that circulating groundwater probably triggered a four-year-long series of tiny quakes in Southern California.

  9. illustration of crocodile ancestors walking on two legs

    Fossil footprints show some crocodile ancestors walked on two legs

    The 106-million-year-old tracks suggest that other puzzling nearby fossils were also likely made by a bipedal croc ancestor, not a giant pterosaur.

  10. mangrove forest

    Rapid sea level rise could drown protective mangrove forests by 2100

    Mangroves have kept up with rising water so far, but new research reveals their limits.

  11. Chicxulub impact illustration

    Chicxulub collision put Earth’s crust in hot water for over a million years

    An asteroid impact 66 million years ago caused hot fluids to circulate in the crust, creating conditions that may have been ideal for microbial life.

  12. a photo showing tree rings

    ‘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.
