The rate of global warming, rather than the extra heat itself, could determine whether a system of ocean currents known as ...

During the last ice age, the Atlantic Ocean's powerful current system remained active and continued to transport warm, salty water from the tropics to the North Atlantic despite extensive ice cover ...

A system of Atlantic Ocean currents that regulates global weather is at its feeblest in 1,600 years, weakened partly by climate change, said researchers Wednesday, warning of trouble ahead. Two ...

A new study suggests that the collapse of the Atlantic Meridional Overturning Circulation—a key current system that helps regulate the planet's climate—can no longer be considered a remote possibility ...

Bivalves, such as clams, oysters and mussels, record seasonal environmental changes in their shells, making them living chronicles of climate history. A new study of bivalve shells has detected two ...

A major Atlantic current could collapse by the middle of the century as a result of climate change, prompting extreme cold in Europe and sea level rise along the eastern coast of the U.S., according ...

When a scientist says, “We don’t know yet,” it can sound like a shrug. In reality, it often means the opposite: We are worried enough to be careful. The public can reasonably ask why some climate ...

Although it can be hard to tell from looking at the often placid waters of the Earth’s oceans, their currents carry immense amounts of water around the globe on a daily basis, underlying a dynamic ...
