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.

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.

Earth Is Spinning Faster, Says Study. This Could Force A Global Time Reset
In a rare and unprecedented move, scientists and world timekeepers are considering reducing one second from Coordinated Universal Time (UTC) as Earth's rotation speeds up.

"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.

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.

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...

Antarctica’s Melting Ice Could Awaken Hidden Volcanoes, Impact Climate Change
As Antarctica’s ice sheet continues to melt, scientists warn it could awaken over 100 hidden volcanoes beneath the surface. The loss of ice reduces pressure on magma chambers, allowing the magma to expand and potentially trigger eruptions. This could lead to increased volcanic activity, releasing gases and heat that may accelerate ice melt, weake...

How A Melting Iceberg Is Reshaping Marine Ecosystems
A massive iceberg, A-68, which broke off from Antarctica's Larsen C Ice Shelf in 2017, has created a distinctive marine environment during its four-year drift, according to recent scientific analyses.
