Off the coast of Antarctica, the sea ice retreated toward the southernmost continent and, like a bottle cap taken off a soda bottle, that reduced pressure slowed down a process of critical carbon ...

A new study shows that during the last two deglaciations, i.e., the transition from an ice age to the warm interglacial periods, meltwater from the Antarctic ice sheet intensified stratification in ...

Cracking, creaking ice at the bottom of the world is quietly shaping the future climate you live in. New research from Australian scientists shows that melting Antarctic ice shelves and changing sea ...

Antarctica holds so much frozen water that if it vanished overnight, the shape of the planet’s coasts, climate and oceans would be unrecognizable within hours. The scenario is wildly unrealistic, but ...

The sea ice surrounding Antarctica has increased in extent and concentration from the late 1970s, when satellite-based measurements began, until 2015. This behavior has presented a conundrum for ...

Around 12,000 years ago, the last Ice Age ended, global temperatures rose and the early Holocene began, during which time human societies became increasingly settled. A new study published in Nature ...

A massive and surprising change is unfolding around Antarctica. Scientists have discovered that the Southern Ocean is getting saltier, and sea ice is melting at record speed, enough to match the size ...

Scientists have uncovered a new threat hiding under the floating edges of Antarctica: fast moving, stormlike swirls of water that attack the ice from below. These secretive currents, spinning in the ...
