  1. Health & Medicine

    Western wildfires’ health risks extend across the country

    As western wildfires become more common, hazardous smoke is sending people — especially children — to emergency rooms on the East Coast.

  2. Earth

    A volcano-induced rainy period made Earth’s climate dinosaur-friendly

    New physical evidence links eruptions 234 million to 232 million years ago to climate changes that let dinosaurs start their climb to dominance.

  3. Ecosystems

    Wildfires launch microbes into the air. How big of a health risk is that?

    How does wildfire smoke move bacteria and fungi — and what harm might they do to people when they get there?

  4. Earth

    Plastic drinking water pipes exposed to high heat can leak hazardous chemicals

    Lab tests exposing commonly used water pipes to wildfire-like heat show damaged pipes can leach the carcinogen benzene and other chemicals.

  5. Earth

    Technology and natural hazards clash to create ‘natech’ disasters

    Hurricanes, wildfires and nature’s other extreme events are increasingly causing damage to infrastructure crucial for safety and communication.

  6. Environment

    Invasive jumping worms damage U.S. soil and threaten forests

    Also known as snake worms, these writhing wrigglers turn forest leaf litter into bare ground, changing soil composition and ecosystems as they go.

  7. Earth

    An asteroid impact, not volcanism, may have made Earth unlivable for dinosaurs

    New simulations add to growing evidence that an asteroid strike, rather than the Deccan Traps eruptions, caused the end-Cretaceous extinction.

  8. Environment

    How giving cash to poor families may also save trees in Indonesia

    Indonesia’s poverty reduction program also reduced deforestation by 30 percent, researchers say.

  9. Earth

    Did heavy rain trigger Kilauea’s eruption? It’s complicated

    A study suggests the Hawaiian volcano’s outpouring of lava was triggered by heavy rainfall in the months preceding. But some scientists are skeptical.

  10. Climate

    Economic costs of rising seas will be steeper than we thought, unless we prepare

    A study estimates 4 percent in annual global GDP losses by 2100 due to sea level rise, unless people curb emissions and prepare for flood risks.

  11. Earth

    The worst wildfires can send smoke high enough to affect the ozone layer

    Pyrocumulonimbus clouds can send soot and other damaging particles 23 kilometers into the air
