Shell shocked: Emerging impacts of our acidifying seas

As Earth’s climate changes, the oceans are becoming more acidic. Here’s how oysters and reefs are responding to their acidifying bath.

Animals

Ocean acidification may ground swimming skates

Fish might seem immune to acidic waters, but check their skeletons. They can be vulnerable and eventually alter how fish behave.

Animals

Scientists Say: Jellies

Jellies have roamed the seas for 500 million years. Some have stinging tentacles and bell-shaped bodies and are called jellyfish. Others are very different.

Climate

Climate change makes seas rise faster and faster

Climate change is boosting the average rate of global sea level rise. Steps can limit the worst impacts and help people adapt. But time to act is running short.

Explainer: Why sea levels aren’t rising at the same rate globally

The ocean is rising all over the world. The rise seems speedier in some places. What gives? Many factors, it turns out, affect where — and why — the tide gets high.

Building resilience to climate’s emerging impacts

The growing field of resilience science studies how communities and habitats can bounce back from stress and disruptions.

Archaeology

Rising seas threaten thousands of world cultural sites

Sea level rise threatens many thousands of cultural and archeological sites around the world.

How three coastal communities are dealing with rising seas

As our climate changes and seas rise, people who live near the ocean are at risk of losing their towns — and homes.

Ecosystems

Welcome to the Arctic’s all-night undersea party

Life teems in the frozen darkness of the Arctic night. But as the ice recedes and people move in, their light pollution may disturb the animals living there.

What makes Aquaman special? He can take a lot of pressure

The new Aquaman movie makes life under the sea look pretty glamorous. In fact, we puny humans probably couldn’t take the pressure.

This robotic jellyfish is a climate spy

Scientists have developed a robotic jellyfish to collect data about the ocean. It’s small and nimble, and gentle on marine ecosystems.

Scientists Say: Rime ice

Rime ice is ice that forms when water freezes in a snap onto a surface.
