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

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

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

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 ...

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

Evidence from fossil shells suggests that falling seawater calcium helped lock away carbon dioxide and helped cool Earth after the dinosaurs.

Meltwater runs across the Greenland ice sheet in rivers. The ice sheet is already losing mass and could soon reach a tipping point. Maria-José Viñas/NASA As the planet warms, it risks crossing ...

Climate change is already fueling dangerous heat waves, raising sea levels and transforming the oceans. Even if countries ...

Greenland is sovereign in everything other than defence and foreign policy, but by being part of the Kingdom of Denmark, it is included within Nato. As with any nation, access to its land and coastal ...

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 ...
