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 ...

New research from the University of Copenhagen suggests that volcanic eruptions during the Ice Age may have triggered sudden climate change by disrupting the Atlantic Meridional Overturning ...

Understanding how the oceans behaved in the past — especially during extremely cold periods — is crucial for testing the models used to project future climate change. The peak of the last ice age, the ...

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 ...

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 ...
