One of the most important functions of the ocean is to move heat around the planet via currents. Think of the ocean as Earth's central heating system, constantly redistributing thermal energy from the ...

Iceland’s relatively mild climate is shaped by a crucial network of currents that winds its away around the Atlantic Ocean transporting heat northward — without it, the island would be much icier and ...

Key Atlantic Ocean currents that appear to be slowing down due to climate change may be more resilient to global warming than scientists previously thought — thanks to a secret back-up system, a new ...

As the planet warms, it risks crossing catastrophic tipping points: thresholds where Earth systems, such as ice sheets and rainforests, change irreversibly over human lifetimes. Melting ice sheets in ...
