This video segment adapted from NOVA scienceNOW features western Greenland's Jakobshavn Glacier, dubbed the world's fastest-flowing glacier. Scientists attempt to explain why this glacier is moving at ...

There is both good and bad news about the conveyor belt of heat-moving currents in the North Atlantic Ocean. A new study of 17 different climate models concludes that the thermohaline circulation, ...

The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. These ...

Sunlight, the ultimate source of all the Earth’s heat, bathes the planet unequally. In equatorial regions, sunlight provides more heat than can radiate into space, and in polar regions more heat ...

One of the odd possibilities that could emerge from global warming is that much of Europe, robbed of the ocean current patterns that help keep it warm, could rather abruptly enter a deep freeze and ...

Currents are like rivers of water within the ocean. They are driven by several factors, including winds, precipitation, evaporation, and heating and cooling of the ocean. They can flow for thousands ...

A powerful ocean current that drives the Gulf Stream and warms temperatures in much of northwestern Europe has weakened dramatically in recent years. That's the conclusion of British scientists, who ...

In 2002, the National Academy of Sciences published a report which concluded that "abrupt climate changes are not only possible but likely in the future, potentially with large impacts on ecosystems ...

A collapse in ocean currents triggered by global warming could be catastrophic, but only now is the Atlantic circulation being properly monitored. Quirin Schiermeier investigates. Henry Ellis, captain ...
