New research challenges the long-held belief that the Arctic Ocean was covered by a massive ice shelf during ice ages.

Global warming caused vital Atlantic Ocean currents to collapse just before the last ice age, a new study suggests. The ...

The Atlantic Ocean currents are slowing down, according to a new study led by a University of Maryland researcher. Specifically, the study found the Atlantic Meridional Overturning Circulation ...

Atlantic Ocean current could collapse soon. How you may endure dramatic weather changes. ... it could bring about an ice age in Europe and sea-level rise in cities such as Boston and New York, ...

Around 10,000 years ago as the last Ice Age drew to a close, the drifting of the continent of North America, and spreading in the Atlantic Ocean, may have temporarily sped up—with a little help from ...

Ocean currents transport heat throughout the globe, but as climate change melts sea ice and causes more rain to fall, a major current circulating through the Atlantic Ocean, AMOC, may be slowing down.

Arctic Ocean was covered by kilometre-thick ice shelf and filled entirely with freshwater, ‘surprising’ new evidence reveals. Extensive glaciation and lower sea levels cut off Arctic from ...

A major current that runs the length of the Atlantic Ocean and plays an important role in the planet's climate may be approaching a tipping point that would lead to its collapse, researchers have ...

Melting that began with the Ice Age’s wane is ongoing, making the oceans minutely fresher. And in the Atlantic Ocean, eelgrass is still trying to regain the genetic diversity it lost when ice ...

Global warming during the Last Interglacial period caused so much Arctic ice to melt that Atlantic currents collapsed — and scientists say these are the conditions we could be heading toward.
