UN Confirms 2015-2025 As Hottest Decade On Record
An increase in the concentrations of greenhouse gases "to their highest level in at least 800,000 years" has "upset this equilibrium," says the WMO.

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.

Watch: Scientists Record First Video Evidence Of Shark In Antarctic's Freezing Waters
For the first time, researchers recorded a three to four-meter shark in Antarctic Ocean waters, challenging the belief that sharks do not inhabit these frigid depths.

Scientists Plan To Build 150-Meter Wall To Mitigate "Doomsday Glacier" Melting Crisis
Experts have acknowledged significant technical challenges, including the wall's survival in extreme Antarctic conditions and long-term ocean exposure.

AIIMS Delhi Doctors Conduct Remote Ultrasound Scans On Volunteers In Antarctica
AIIMS Delhi doctors remotely performed real-time ultrasound scans on Indian Antarctic station volunteers using a telerobotic system.

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...

Antarctic Ozone Layer Shows Signs Of Recovery: NASA
The Antarctic ozone layer is showing signs of recovery, reaching an annual maximum of 8.83 million square miles on September 9, scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) said.

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...

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.
