When most of us look out at the ocean, we see a mostly flat blue surface stretching to the horizon. It’s easy to imagine the ...

Scientists studying ancient ocean fossils found that the Arabian Sea was better oxygenated 16 million years ago, even though ...

Each year, vast blooms of phytoplankton spread across the Southern Ocean, drawing carbon dioxide from the atmosphere and ...

Melting ice could weaken Earth's strongest ocean current 20% by 2050, study reveals.

During the last ice age, the Atlantic Ocean's powerful current system remained active and continued to transport warm, salty ...

The last ice age did not shut down Atlantic ocean currents, and that discovery may help explain future climate risks.

Much of Earth's heat uptake is passed to the ocean, making ocean heat content key for understanding long-term climate patterns. Ocean heat content is typically lower during ice ages and rises during ...

A conveyor belt of ocean water that loops the planet and regulates global temperatures could be heading for a tipping point.

Global ocean heat content increased by approximately 23 zetajoules (ZJ) in 2025, roughly 40 times annual global primary energy consumption. This is not good.
