Record-Breaking Drill Beneath Antarctic Ice Reveals Ancient Open Ocean and Future Sea Level Risks
Scientists drilled deeper than ever beneath the West Antarctic Ice Sheet and found sediment and marine remains showing the area was once open ocean. The 23-million-year record offers key clues about past melting, helping researchers better predict how quickly the ice sheet could retreat and affect future global sea levels.

NASA Spots Giant Antarctic Iceberg Turning Blue as It Nears Breakup
NASA scientists are closely tracking iceberg A-23A as vivid blue meltwater pools spread across its surface, signalling rapid decay. Once covering nearly 4,000 square kilometres, the Antarctic megaberg has shrunk to about 1,180 square kilometres and is fragmenting in warmer South Atlantic waters, offering valuable insight into how rising temperature...

Antarctica Nears Irreversible Climate Tipping Point, Scientists Warn
Antarctica is approaching irreversible climate thresholds, scientists warn. Rapid melting of the West Antarctic Ice Sheet, record-low sea ice, and collapsing ocean systems could raise global sea levels by over 3 m. These interconnected changes threaten coastal cities and ecosystems, urging immediate emission cuts to prevent cascading global consequ...

Antarctic Winter Sea Ice Hits Third-Lowest Level In 47 Years
Antarctica's winter sea ice has hit its third-lowest peak in nearly half a century of satellite monitoring, researchers said Tuesday, highlighting the growing influence of climate change on the planet's southern pole.

Satellite Observations Record Arctic Sea Ice at Lowest Level of the Year
NASA satellites recorded Arctic sea ice at 1.78 million sq miles on Sept. 10, 2025—its tenth-lowest extent. Antarctic ice also stayed below seasonal averages. Scientists stress these lows reflect long-term climate-driven changes reshaping Earth’s polar regions.

Sea Ice To Ocean Currents, Antarctica Is Undergoing Abrupt Changes
Melting sea ice allows oceans to warm more rapidly, which melts more sea ice. Once triggered, they can be difficult or even impossible to reverse on timescales meaningful to humans.

Global Antarctic Research Declines Amid Growing Climate Crisis
Ice loss in Antarctica and its impact on the planet - sea level rise, changes to ocean currents and disturbance of wildlife and food webs - has been in the news a lot lately.

What Ancient Ice Sheets Can Tell Us About Future Sea Level Rise
When visiting Godrevy beach on the north Cornish coast, most people look out to sea at the lighthouse, surfers and seals rather than the cliffs behind.

Antarctic Ice Melt Weakens Strongest Ocean Current, Disrupting Global Circulation
The Antarctic Circumpolar Current, the planet’s most powerful ocean circulation system, could slow by 20 percent by 2050 due to melting Antarctic ice. Researchers suggest that the influx of fresh, cold water is disrupting convection, altering global ocean density. A weaker current may allow warm water to reach Antarctica, accelerating ice loss an...

Global Sea Ice Cover At Record Low In February Amid Persistent Hot Streak
In February, temperatures spiked up to 11 degrees Celsius above average near the North Pole as the world continued its persistent heat streak, said Europe's climate monitor.
