1. Science & Society

    Could climate change worsen global conflict?

    Famine, natural disasters and sea-level rise can all disrupt societies. These can add pressure to unstable regions — sometimes to the point of prompting wars.

  2. Health & Medicine

    Warning: Climate change can harm your health

    Climate change will affect human health through such things as more frequent bouts of extreme weather, shifts in disease patterns, changes in air and water pollution.

  3. Health & Medicine

    Climate change poses mental health risks to children and teens

    Climate change doesn’t just hurt people’s physical health. It’s bad for mental health, too. Children and teens are especially at risk, say experts.

  4. Health & Medicine

    Workers won’t work as well in a very warm world

    How well and how much people are able to work will suffer because of heat stress in a warming world. That, in turn, can lead to additional health impacts.

    Explainer: How heat kills

    The human body is good at cooling itself off. But it has limits.

  6. Earth

    Strange lake belches flammable gas in the high Arctic

    Lake Esieh is bubbling out surprising amounts of methane, a greenhouse gas. Scientists wonder if it’s one of a kind, or a warning of more to come.

  7. Ecosystems

    Warming pushes lobsters and other species to seek cooler homes

    Plants and animals are moving toward the poles, changing timing of important events and more — all in response to climate change.

  8. Ecosystems

    Photographing wildflowers and other ways you can help fight climate change

    Citizen scientists can help with climate and conservation research by counting birds, taking pictures of flowers and deciphering old weather records.

  9. Oceans

    Oceans’ fever means fewer fish

    Warming oceans have caused fish populations to plummet since 1930. In some regions, the number of fish that can be caught without depleting populations has dropped by more than one-third.

    Using art to show the threat of climate change

    Climate change can sometimes seem like a huge pile of hard-to-grasp numbers and graphs. These artists are finding new ways to help people understand big changes.

  11. Physics

    Thunderstorms hold stunningly high voltage

    By studying particles called muons, scientists found that the electric potential inside a thunderstorm may be 10 times higher than previously thought.

    Disappearing sea ice could disrupt Arctic’s food web

    When sea ice goes missing in the Arctic, every part of the ecosystem feels the effects.
