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...

Antarctic Ice Sheet Melting May Intensify Volcanic Eruptions, Study Finds
The melting of Antarctic ice sheets is linked to more intense and frequent volcanic eruptions, as found by recent research. Reduced ice mass alleviates pressure on magma chambers beneath the surface, causing them to expand and release volatile gases, which can lead to eruptions. A study has drawn connections between this process and increased volca...

Rare Sea Smoke and Streaming Snow Phenomena Captured Near Pine Island Glacier
In October 2024, Pine Island Glacier displayed unusual atmospheric phenomena, including rare sea smoke and blowing snow. Captured by NASA's Landsat 8, these events were visible due to clear skies. Strong winds pushed warmer water to the surface, creating sea smoke, while blowing snow from the West Antarctic Ice Sheet influenced the glacier’s land...

Antarctic Study Reveals "Tipping Point" For Runaway Melting Of Ice Sheets
Scientists have discovered a new tipping point toward "runaway melting" of Antarctic ice sheets, caused by warm ocean water intruding between the ice and the land it sits on, according to a study published on Tuesday.

Climate Change Key Factor Of Record-Low Antarctic Sea Ice: Study
Climate change played a key role in last year's record-low levels of Antarctic sea ice, a study published on Monday found, marking an abrupt shift from the growth seen in previous decades.

Antarctic Wildlife Is Being Sunburnt. Scientists Say It's A "Wake-Up Call"
The ultraviolet radiation from the Sun increase the risk of skin cancer and cataracts in humans, but researchers do not yet know if the same is true for Antarctic mammals and birds.

Antarctic Ice Sheet Collapse Closer Than Thought, Reveals Octopus DNA
Scientists investigating how Antarctica's ice sheets retreated in the deep past have turned to an innovative approach: studying the genes of octopuses that live in its chilly waters.

Viral Image Shows Pink Flowers Blooming In Antarctica, Here's The Truth
Many users pointed out that the image is misleading and fake, and such claims have gone viral in the past too.

Scientist Studying Antarctica For 40 Years On Why It Needs Our Help Now
After decades immersed in Antarctic science, Ive learned that physical and biological changes rarely occur smoothly. More often than not, they unfold in sharp steps. Right now, Antarctica's climate and ecosystems are experiencing disturbing changes.

Scientists Race Against Time To Preserve "Ice Memory" For Future Studies
Scientists camped in the Arctic are set to start drilling to save samples of ancient ice for analysis before the frozen layers melt away due to climate change, mission organisers said on Monday.

Giant Iceberg, Bigger Than Size Of Delhi, Breaks Off From Antarctic Ice Shelf
The massive iceberg, which is nearly 600 square miles (1550 sq km), broke free from the 492ft-thick (150m) Brunt Ice Shelf on Sunday.

Scientists Discover Huge River Hidden Under Antarctica
Glaciologists say that the river has the potential to substantially affect the way the glacial ice above it flow and melts.

NASA’s Satellite Imagery Shows Antarctic Ice Shelf Crumbling Faster Than Imagined
NASA’s recent study led by researchers from the Jet Propulsion Laboratory (JPL) has revealed that Antarctica's coastal glaciers are shedding icebergs more rapidly than nature can replenish the crumbling ice. This raises new concern about how fast climate change is weakening Antarctica's floating ice shelves and accelerating the rise of global sea...

Antarctic Ice Shelf, Almost As Big As Rome, Collapses As Temperature Rises
The temperature in East Antarctica rose to minus 11.8 degrees Celsius last week, more than 40 degrees Celsius warmer than the seasonal norm.
