Since the discovery 50 years ago of subglacial lakes in Antarctica — some of the least accessible geological features on Earth — scientists have attempted to extract lake bed sediment to learn about the formation, movement and past conditions of the ice sheet. Now, a team of researchers with the…

Antarctic sea ice reached its lowest extent in the 45-year satellite data record last month - Copyright AFP - Marlowe HOOD Sea ice in Antarctica shrank to the smallest area on record in February for the second year in a row, continuing a decade-long decline, the European Union’s climate monitoring…

Earth’s climate is controlled by a complex network of interactions between the atmosphere, oceans, lands, ice and biosphere. Many elements in this system are now being pushed toward tipping points, beyond which changes become self-sustaining, with the whole Earth system potentially shifting to a new steady state.A recent study analyzed…

Mosses, one of the few types of plants living in Antarctica, have a tenuous existence, threatened by advancing glaciers. When glaciers move, they can entomb or cover a plant — starving it of light and warmth. Scientists have discovered that the timing of when a glacier killed a moss, the…

(Image credit: Antony Gilbert)Rare sightings of giant phantom jellyfish — deep-sea creatures that look like UFO spaceships with thick ribbons streaming from their undersides — have been reported by cruise liner passengers who spotted the…

Mission Blue has announced its latest “Hope Spot” in East Antarctica. The new East Antarctic Hope Spot is home to a myriad of wildlife, including seals, penguins, whales, and toothfish. The presence of sea ice in this area is essential for many species, including Antarctic silverfish and krill, according to…

A pair of studies this week have shed new light on the melting of the Thwaites Glacier, one of Antarctica’s largest and most menacing stretches of ice. Often referred to as the “Doomsday Glacier,” it contains enough ice to raise global sea levels by about 2 feet all on its…
