Studies find West Antarctica’s ice sheet is melting faster. But a new look at the ancient past suggests it once pushed sea levels up by three metres

Ice cores pulled from miles below Antarctica’s surface are revealing new evidence of ancient links between the climates of Earth’s Northern and Southern hemispheres.

The last glacial period exhibited abrupt Dansgaard–Oeschger climatic oscillations, evidence of which is preserved in a variety of Northern Hemisphere palaeoclimate archives. Ice cores show that Antarctica cooled during the warm phases of the Greenland Dansgaard–Oeschger cycle and vice versa, suggesting an interhemispheric redistribution of heat through a mechanism called the bipolar seesaw.

A new study using evidence from a highly detailed ice core from West Antarctica shows a consistent link between abrupt temperature changes on Greenland and Antarctica during the last ice age, givin

Anaesthetic gases may help doctors to cause temporary loss of sensation in patients and carry out surgery smoothly, but by accumulating in the Earth's atmosphere, they also contribute to climate ch

Icebergs breaking away from the Antarctic ice sheets every year contain enough water to fill the Three Gorges reservoir nineteen times, according to a study by Chinese scientists.

The ice around the edge of Antarctica is melting faster than previously thought, potentially unlocking metres of sea-level rise in the long-term, researchers have warned.

A warming ocean is pouring through newly discovered rivers under the largest glacier in East Antarctica, confirming this sleeping giant of climate change is awakening.

The behavior of marine-terminating ice sheets, such as the West Antarctic ice sheet, is of interest due to the possibility of rapid grounding-line retreat and consequent catastrophic loss of ice. Critical to modeling this behavior is a choice of basal rheology, where the most popular approach is to relate the ice-sheet velocity to a power-law function of basal stress. Recent experiments, however, suggest that near-grounding line tills exhibit Coulomb friction behavior. Here we address how Coulomb conditions modify ice-sheet profiles and stability criteria.

From the ground on Cape Legoupil in the extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever.
