New Study Shows Antarctic Waters Unleashed Ancient Carbon at the Ice Age’s End
New research shows that shifting Antarctic circulation after the last Ice Age released ancient deep-ocean carbon into the atmosphere. Using Southern Ocean sediment cores, scientists traced how expanding Antarctic Bottom Water mixed long-isolated, carbon-rich waters upward. The findings reveal a major but underappreciated driver of early Holocene wa...

Scientists Warn Southern Ocean Could ‘Burp’ Stored Heat, Delaying Global Cooling for 100 Years
New modelling suggests the Southern Ocean could one day release the vast heat it has stored from greenhouse gas pollution. If CO₂ levels were pushed to net-negative, deep convection may trigger a sudden “thermal burp” that warms the planet for decades. Though idealised, the study shows how Antarctica’s surrounding seas could shape long-term...

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...

Antarctica Sees Similar Climate Change Effects As Greenland: Study
The planet's warming climate is having effects in Antarctica that increasingly resemble those observed in the Arctic, meaning global sea levels could rise faster that previously predicted, Danish researchers warned.

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.

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.

From Antarctica To Brussels, Hunting Climate Clues In Old Ice
Ice dating back millions of years can be found deep inside Antarctica, close to the South Pole, buried under kilometres of fresher ice and snow.

"More Explosive And Frequent": Melting Glaciers Might Trigger Volcanic Eruptions Globally, Study Warns
As global temperatures rise and the ice melts, the loss of weight and pressure can trigger explosive eruptions.

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.

NASA Satellite Shows World's Largest Iceberg Breaking Into Thousands Of Pieces. What Happens Next
The A23a iceberg, deemed the largest in the world since 2023, was seen losing large chunks of ice after drifting toward the island of South Georgia.

New Study Reveals Recent Ice Gains in Antarctica, But Long-Term Melting Continues
A study led by researchers at Tongji University using NASA's GRACE satellites has observed recent ice gains in Antarctica from 2021 to 2023, mainly due to unusual precipitation. However, the long-term satellite data from 2002 to 2020 shows a significant and accelerating trend of ice loss. However, experts emphasize this short-term gain does not rev...

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...

World’s Largest Iceberg A23a Grounds Near South Georgia, Raising Wildlife and Environmental Concerns
The world’s largest iceberg, A23a, has run aground near South Georgia, a key wildlife haven. Scientists are monitoring its impact on marine life, particularly on penguins and seals, as it could disrupt feeding routes. Some experts suggest the iceberg may also enhance ocean productivity by releasing nutrients. If it fragments, it may pose risks to...

Earth's Strongest Ocean Current Is Slowing Down And It Could Have Devastating Consequences
The ocean current might slow down by around 20 per cent by 2050 in the "high carbon emissions scenario".
