Undersea anchors of ice that help prevent Antarctica's land ice from slipping into the ocean are shrinking at more than twice the rate compared with 50 years ago, research shows. More than a third of these frozen...
An international team of scientists from China, the U.S. and Europe has studied new fossils of the marine reptile Dinocephalosaurus orientalis. This research has made it possible to fully describe the bizarre, very impressive animal for...

Researchers find Antarctic ice shelves thinner than previously thought

As global ice dams begin to weaken due to warming temperatures, a new study suggests that prior attempts to evaluate the mass of the...

Dangerous slowing of Antarctic ocean circulation sooner than expected

Scientists have said that an acceleration of melting Antarctic ice and rising temperatures, driven by the emission of planet-warming gases, is expected to have...

Why Antarctic ice shelves are losing their mass and how it leads to global sea level rise

The Greenland ice sheet (GIS) and Antarctic ice sheet (AIS) contribute largely to global mean sea level (GMSL) changes, though the seas surrounding the...

‘Devastating’ melt of Greenland, Antarctic ice sheets found

The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago,...

Massive Australia wildfires increased Antarctic ozone hole: Study

Smoke from monster wildfires in Australia caused a chemical reaction that widened the ozone hole 10 percent, researchers said Wednesday, raising fears that increasing...

How thick is Antarctic ice, and what is underneath?

Ice at the edge of the Antarctic continent hosts a flourishing ecosystem. Seals and penguins breed, fish mature, and algae thrive, all thanks to...

Drilling campaign reaches a depth of 808 meters in the Antarctic ice sheet

In Antarctica, the second drilling campaign of the Beyond EPICA—Oldest Ice project, at the remote field site Little Dome C, has been successfully completed....

Vast iceberg breaks off near UK Antarctic base

A huge iceberg nearly the size of Greater London has broken off the Antarctic ice shelf near a research station, the second such split...

Runaway West Antarctic ice retreat can be slowed by climate-driven changes in ocean temperature

New research finds that ice-sheet-wide collapse in West Antarctica isn't inevitable: the pace of ice loss varies according to regional differences in atmosphere and...

Study identifies new cause of melting Antarctic ice shelves

Researchers have discovered a process that can contribute to the melting of ice shelves in the Antarctic. An international team of scientists found that adjacent...

Scientists expose vulnerabilities of critical Antarctic ice shelf

Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 meters, could be more vulnerable to...

Record of Antarctic ice sheet response to climate cycles found in rock samples

By analyzing unusual rock samples collected years ago in Antarctica, scientists at the University of California, Santa Cruz, have discovered a remarkable record of...
