Verschillende pinguïnsoorten op Antarctica broeden steeds vroeger. Dat blijkt uit onderzoek van de Penguin Watch van de Oxford-universiteit, die de pinguïns gedurende 10 jaar observeerde. Experts vrezen dat 3 pinguïnsoorten daardoor op lange termijn met uitsterven bedreigd zijn.

Glacial earthquakes are a special type of earthquake generated in cold, icy regions. First discovered in the northern hemisphere more than 20 years ago, these quakes occur when huge chunks of ice fall from glaciers into the sea. Until now, only a very few have been found in the Antarctic. In a new study soon to be published in Geophysical Research Letters, I present evidence for hundreds of these quakes in Antarctica between 2010 and 2023, mostly at the ocean end of the Thwaites Glacier – the so-called Doomsday Glacier that could send sea levels rising rapidly if it were to collapse.

The 511 billion barrels reported is nearly double Saudi Arabia’s proven reserves and more than ten times the North Sea’s output over the last 50 years.

New research catalogs several “abrupt changes,” like a precipitous loss of sea ice, unfolding in Antarctica with dire implications for us all.

The vast ice of Antarctica has long seemed impregnable. But sudden changes are arriving – from shrinking sea ice to melting ice sheets and slowing ocean currents.

Het zeewater rond Antarctica werd het afgelopen decennium steeds zouter, blijkt uit een nieuwe studie. Hoe dat kan, kunnen de onderzoekers nog niet verklaren. Wat betekent dit voor het klimaatprobleem?

In March 2022, a New York City-sized ice shelf collapsed in East Antarctica, long thought to be relatively stable against rapid change. The Conger-Glenzer ice shelf collapsed following decades of ocean-induced thinning, allowing its long-stabilizing features to transform into destabilizing ones.

A new declaration aims to make the southernmost continent an autonomous legal entity, akin to a nation-state, with inherent rights to participate in decision making that affects it.

De oppervlakte van het Antarctisch Schiereiland waar planten groeien, is vandaag minstens 12 keer groter dan in 1986. Dat blijkt uit satellietfoto's. De vergroening van de Zuidpool, door de klimaatverandering, gaat steeds sneller. Daardoor zou Antarctica er binnen enkele decennia wel eens heel anders kunnen uitzien.

As a six-year investigation into the Thwaites glacier in Antarctica wraps up, the scientists involved are pessimistic for the future of this glacier and the consequences for sea level rise
