  1. Climate

    Ship exhaust studies overestimate cooling from pollution-altered clouds

    Lines of clouds formed by ship exhaust offer a window into aerosol-cloud interactions but may overestimate how much pollution-altered clouds cool the climate.

  2. Climate

    How much will Africa capitalize on cheap renewable energy as its power grid grows?

    An analysis of the successes and failures of past electrical power projects across Africa suggests the continent isn’t likely to go green before 2030.

  3. Climate

    ‘The New Climate War’ exposes tactics of climate change ‘inactivists’

    In his new book, climate scientist Michael Mann draws the battle lines for a new phase of the struggle against climate change denialism.

  4. Climate

    2020 and 2016 tie for the hottest years on record

    Ocean temperature data as well as temperatures measured over land at weather stations around the globe revealed the extent of the warming.

  5. Earth

    How the Earth-shaking theory of plate tectonics was born

    Plate tectonics explains many of Earth’s geologic wonders and natural hazards — and may hold clues to the evolution of life.

  6. Paleontology

    Newborn megalodon sharks were larger than most adult humans

    Preserved pieces of backbone suggest that megalodon sharks were about 2 meters long at birth.

  7. Earth

    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.

  8. Climate

    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.

  9. Climate

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

    Climate change did not take a break during the pandemic.

  10. Earth

    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.

  11. Paleontology

    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.

  12. Climate

    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.
