Table salt and shellfish can contain plastic
Bits of plastic have turned up in sea salts purchased in Chinese supermarkets. The finding suggests all sea salts may be similarly tainted. Shellfish too.

Plastic trash travels up to Arctic waters
Bags, fishing rope and other tiny bits of plastic are now polluting Arctic waters, posing threats to area wildlife.

Explainer: What is a tsunami?
Earthquakes and landslides can create huge waves that travel across oceans.

Carbon dioxide levels rise fast and high
The buildup of carbon dioxide in the atmosphere is rising faster than at any time since dinosaurs roamed the Earth. The burning of fossil fuels is largely to blame.

Deep-sea fish show signs of exposure to pollution
A new study suggests deep-water fish may have health problems linked to human pollution. Eating these fish may expose diners to the same pollution.

Fracking wastes may be toxic, tests show
Fracking operations have been polluting the environment. Some wastes have hormonal effects. Studies in mice now show that prenatal exposures to these wastes can trigger subtle but disturbing organ impacts.

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.
- 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.

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.

Air pollution can mess with our DNA
New research suggests a type of air pollution — diesel fumes — can affect your health. It inappropriately switches some genes on, while turning off others.

Picture This: Christmas from space
Satellite images show that cities brighten during holidays. Charting such changes can point to factors affecting energy use and contributing to global warming.
