It’s part of the scenario in “The Day After Tomorrow,” but scientists differ over whether or how fast it may occur. A team ...

As global electricity use grows, the strain on traditional energy sources increases. Renewable options like wind and solar have become popular, yet there's a massive, largely untapped resource beneath ...

This experiment demonstrates how water at different temperatures has different densities, creating beautiful layering effects. You'll see how warm and cold water interact and learn about density ...

Ocean currents driven by wind, water density, tides, ocean floor features, or the Coriolis effect, have an important role on climate regulation and marine ecology. In turn, increasing water surface ...

Melting ice sheets are slowing the Antarctic Circumpolar Current (ACC), the world’s strongest ocean current, researchers have found. This melting has implications for global climate indicators, ...

The global ocean “conveyor belt” circulation, shown in part here as red and blue lines, circulates cooler seawater below the surface and warmer seawater at the surface throughout the world’s oceans.
