    Creative ways to help coral reefs recover

    Coral reefs are under siege from threats ranging from climate change to explosives. But scientists are developing ways to rebuild reefs before they disappear.

  2. Teachers talk about climate change, and kids are listening

    Teachers may help convince students that climate change is real. But when it comes to what’s behind that change, many kids appear to rely on more than those educators.

    Algae embedded in sea ice drive the Arctic food web

    Scientists traced where zooplankton in the Arctic get their energy from. Many open ocean species rely on algae found in sea ice, which is disappearing.

    Scientists Say: Albedo

    To measure how much light reflects off an object, scientists measure its albedo.

    Current coral bleaching event is the longest known

    Heat stress has led to the longest coral bleaching event on record. Scientists now worry that global warming may make such prolonged crises more frequent.

    Zapping clouds with lasers could alter Earth’s climate

    Scientists zapped ice crystals in a lab. They were exploring whether this approach might be used to break those crystals in clouds — potentially as a way to cool Earth’s fever.

    Heat sickness

    Scientists worry that increasing temperatures could combine with air pollution to up rates of illness and premature death — perhaps dramatically.

    Polar bears swim for days as sea ice retreats

    Melting sea ice is forcing polar bears to swim long distances — up to nine days in one case. Such long treks may be more than the bears can handle.

    Particles in air help fatten clouds’ water droplets

    Making their own clouds has shown scientists how the fattest water droplets form. Understanding this could lead to better forecasts of climate change.

    Concerns about Earth’s fever

    Burning fossil fuels is causing the planet to heat up, causing weather patterns to change, sea levels to rise and diseases to spread.

    Explainer: How scientists know Earth is warming

    Scientists can calculate global temperatures, both present and past. Their findings show that the planet is rapidly heating up.

    Clues to the Great Dying

    Millions of years ago, nearly all life on Earth vanished. Scientists are now starting to figure out what happened.
