    A new roadmap shows how the U.S. could be carbon-neutral by 2050

    A new report charts a roadmap for the U.S. to have zero carbon footprint by 2050, but only with heavy and immediate investment in carbon removal technologies.

  2. micrometeorites

    Tiny meteorites suggest ancient Earth had a carbon dioxide–rich atmosphere

    Simulations of reactions between 2.7-billion-year-old micrometeorites and atmospheric gases hint Archean Earth’s atmosphere had high levels of CO2.

  3. Ganges River delta

    Fed by human-caused erosion, many river deltas are growing

    Deforestation and river damming are changing the shape of river deltas around the globe.

  4. Westerb Ghats mountains

    Volcanic gas bursts probably didn’t kill off the dinosaurs

    A new timeline for massive bursts of volcanic gases suggests the Deccan Traps eruptions weren’t the real dinosaur killer 66 million years ago.

  5. Tel Aviv heat wave

    2019 was the second-warmest year on record

    2019 was the second-warmest year on record, ending a decade that topped 140 years of heat records.

  6. Amazon fire

    Wildfires could flip parts of the Amazon from a carbon sponge to a source by 2050

    Climate change and deforestation could double the area burned by fire in the southern Amazon by 2050, flipping the forest from carbon sponge to source.

  7. Lake Tabourie fire

    Here’s how climate change may make Australia’s wildfires more common

    An El Niño–like ocean-atmosphere weather pattern called the Indian Ocean dipole helped fuel extremely dry conditions in Australia.

  8. Joint Polar Satellite System-1

    Climate models agree things will get bad. Capturing just how bad is tricky

    Climate models are better than ever at simulating complex interactions between ocean, air, ice and land. But scientists still aren’t really sure what the worst-case scenario might be for Earth’s future climate.

  9. Greenland rocks

    Debate over signs of early life inspires dueling teams to go to Greenland — together

    The remote site — which may or may not contain evidence of the most ancient life on Earth — could help scientists plan how to study such signs on Mars.

  10. Australopithecus anamensis reconstruction and skull

    Science News’ favorite fossils of 2019

    Fossil discoveries reported this year included Cambrian creatures, ancient bone cancer and a peek at life’s recovery after the dinosaur die-off.

  11. youth climate activists

    Record-breaking heat amplified waves of student climate protests in 2019

    While the world experienced record-breaking heat, Greta Thunberg and other activists pushed decision makers to take climate change seriously.

  12. algal bloom

    Flooding Earth’s atmosphere with oxygen may not have needed a triggering event

    Building an oxygen-rich world doesn’t require volcanism, supercontinent breakups or the rise of land plants — just nutrient cycling, a study finds.
