Explainer: Understanding plate tectonics
Plate tectonics is the process whereby Earth continually rebuilds itself — and causes destructive events like earthquakes and volcanic eruptions.

Arctic warming bolsters summer heat
Rapid warming in the Arctic is sapping summer storms of their power to cool. That worsens heat waves across the Northern Hemisphere.

Finding out why birds are out of range
Sometimes people see large numbers of birds outside of their normal range. A student examined how to predict these excursions.

Corals dine on microplastics
Plastic in the ocean is a growing problem. New research finds that corals may eat tiny bits of plastic, prompting new concerns about the health of living reefs.

Ancient ocean linked to supercontinent’s breakup
The supercontinent Pangaea started breaking apart 200 million years ago. This may have been triggered by the shrinking of the Tethys Ocean, a new study finds.

News Brief: Volcanic spark zaps ash to glass
The lightning associated with some erupting volcanoes can be quite crafty — turning ash into lots of microscopic glass beads.
- Climate
Buildings may be chasing L.A.’s fog away
Roads and buildings that have mushroomed up around Los Angeles in the past half-century. Now, a study finds they may have created conditions that limit fog. And that could further dry out this very arid part of America’s West Coast.

Scientists confirm ‘greenhouse’ effect of human’s CO2
Government scientists link directly, for the first time, a boost in warming at Earth’s surface to increasing levels of carbon dioxide. Much of that gas has been released by human activities, such as coal burning and gas-burning vehicles.

Cats and foxes are eating up Australia’s mammals
Since the arrival of Europeans in Australia, a startling number of mammal species have disappeared. A new study puts much of the blame on cats and foxes introduced by the early settlers.

Hellbenders need help!
Hellbenders already face threats such as habitat loss, pollution and disease. But climate change could make matters worse. And the problems facing hellbenders could spell trouble for more than just these giant amphibians.

Distant pollution may intensify U.S. twisters
A new study of one of the deadliest U.S. outbreaks of tornadoes sees a possible role for smoke. In this analysis, the smoke had come from fires burning in Central America.
