Arctic
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.
Global warming has already caused the Arctic to release more climate-warming methane—but exactly how much will depend closely on the actions we take to halt climate change.

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
Het gat in de ozonlaag is zich pas begin deze maand beginnen vormen, later dan normaal. Dat meldt de Europese aardobservatiedienst Copernicus. Het gat is daardoor ook kleiner dan de voorgaande jaren. Dat heeft vooral te maken met de temperatuur van de stratosfeer boven Antarctica, die deze zomer bokkensprongen maakte.
The Svalbard archipelago’s ice caps suffered extreme episodes of melting in summer 2024, brought on by exceptionally high air temperatures.
Blog edited by Sam Carana, with news on climate change and warming in the Arctic due to snow and ice loss and methane releases from the seafloor.
De hele mensheid profiteert van Antarctica en de oceaan die het continent omringt, schrijven Natalie Stoeckl en Rachel Baird, hoogleraren aan de Universiteit van Tasmanië. Een schatting van de economische waarde kan volgens hen een goede motivatie zijn voor de bescherming van dit unieke ecosysteem.
Marine heat waves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions, according to a study just released by Dr. Armineh Barkhordarian from Universität Hamburg's Cluster of Excellence for climate research CLICCS. Since 2007, conditions in the Arctic have shifted, as confirmed by data recently published in the journal Communications Earth & Environment. Between 2007 and 2021, the marginal zones of the Arctic Ocean experienced 11 marine heat waves, producing an average temperature rise of 2.2 degrees Celsius above seasonal norm and lasting an average of 37 days. Since 2015, there have been Arctic marine heat waves every year.
A new paper published in the journal Science has warned that melting areas in the Arctic have become 'frontlines for resource extraction', describing it as a 'modern day gold rush'.
Antarctica’s sea ice levels are plummeting as extreme weather events happen faster than scientists predicted
Le président russe Vladimir Poutine a donné jeudi à Mourmansk le coup d'envoi de la première chaîne d'Arctic LNG 2, gigantesque projet de gaz naturel liquéfié (GNL) dans l'Arctique, dont le français TotalEnergies s'est retiré en 2022.
As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research published in Nature Geoscience. The study, led by researchers from the University of Cambridge and the University Center in Svalbard, Norway, identified large stocks of methane gas leaking from groundwater springs unveiled by melting glaciers.
It was the hottest June on record, unprecedented North Atlantic warmth, record low Antarctic sea ice
(06/07) - World Meteorological OrganizationThe world just had the hottest June on record, with unprecedented sea surface temperatures and record low Antarctic sea ice extent, according to a new report.
Ice-free summers inevitable even with sharp emissions cuts and likely to result in more extreme heatwaves and floods
De ijskappen op Groenland en Antarctica smolten nooit zo snel dan de voorbije tien jaar. De slechtste zeven jaar sinds het begin van de metingen hebben zich in het afgelopen decennium voorgedaan. Wetenschappers wijzen de klimaatverandering aan als schuldige.
Seafloor landforms reveal that ice sheets can collapse at 600 metres per day.
De diepzeestromingen rond het Antarctische continent tonen tekenen van vertraging, stelt onderzoek in Nature. Een totale ineenstorting zou wereldwijde gevolgen hebben voor de oceanen en het klimaat.
With the continent holding enough ice to raise sea levels by many metres if it was to melt, polar scientists are scrambling for answers
Sommige koude ijsplaten op Antarctica, waarvan onderzoekers aanvankelijk dachten dat ze de komende eeuwen stabiel zouden blijven, blijken toch kwetsbaar als de aarde verder opwarmt. Dat stelt een studie in Nature.
From the seemingly inexorable increase of carbon dioxide in the atmosphere to the rapid growth in green energy
An international team of researchers have sounded new alarm bells about the changing chemistry of the western region of the Arctic Ocean after discovering acidity levels increasing three to four times faster than ocean waters elsewhere. The team, which includes University of Delaware marine chemistry expert Wei-Jun Cai, also identified a strong correlation between the accelerated rate of melting ice in the region and the rate of ocean acidification, a perilous combination that threatens the survival of plants, shellfish, coral reefs and other marine life and biological processes throughout the planet's ecosystem.
Giant ice sheets, ocean currents and permafrost regions may already have passed point of irreversible change

Zweedse wetenschappers luiden alarmbel: overal 'forever chemicals' in regenwater, tot Antarctica toe
(15/08) - Vincent MerckxWereldwijd worden er hogere concentraties PFAS in regenwater aangetroffen dan Europese en Amerikaanse gezondheidsnormen toestaan. Dat besluit Zweeds onderzoek. Het toont aan hoe moeilijk de 'forever chemicals' uit de wereldwijde waterkringloop raken. De wetenschappers pleiten er daarom voor om het gebruik van PFAS zo snel mogelijk te verbieden waar mogelijk.
The Earth is approximately 1.1℃ warmer than it was at the start of the industrial revolution. That warming has not been uniform, with some regions warming at a far greater pace. One such region is the Arctic. A new study shows that the Arctic has warmed nearly four times faster than the rest of the world over the past 43 years. This means the Arctic is on average around 3℃ warmer than it was in 1980.
Russian energy company Rosneft announced the discovery of a massive oil resource in the Pechora Sea with an estimated 82 million tons of oil. A drilling campaign in the Medynsko-Varandeysky area led to the discovery of the field. “During the tests, a free flow of oil was obtained with a maximum flow rate of 220 cubic meters a day,” the company’s statement read on Wednesday, noting that the “oil is light, low-sulfur, low viscosity.” According to Rosneft, the exploratory work in the Pechora Sea confirmed the "substantial oil potential of the Timan-Pechora province on the shelf and served as the foundation for continuing the study and development of the region."
Een wereld waarin het plastic sneeuwt op Antarctica en in de oceanen is meer dan zorgelijk, schrijft MO*columniste Tine Hens. Het is moeilijk zinvolle argumenten bij elkaar te schrapen om te verantwoorden dat je toch nog een nieuwe plasticfabriek nodig hebt in een wereld die stikt in sporen van plastic.
Climate tipping points in the Antarctica, the Arctic and the Amazon are at risk of being reached before or at the current level of global warming of 1.2 degrees Celsius, requiring a “major rethink” of global climate goals and the action necessary to achieve them, according to a recent report.
The rapid collapses of two ice shelves on the Antarctic Peninsula over the past quarter-century were most likely triggered by the arrival of huge plumes of warm, moisture-laden air that created extreme conditions and destabilized the ice, researchers said Thursday.
As climate crisis allows new maritime routes to be used, sooty shipping emissions accelerates ice melt and risk to ecosystems
We may lose up to three meters of coastline in the Arctic every year by 2100 if greenhouse gas emissions are not reduced, according to a study published in the journal Nature Climate Change. The authors also warn about bigger waves due to increasing temperatures, making the coastline very vulnerable to further losses due to erosion.
A chunk of Antarctic ice that was one of the biggest icebergs ever seen has met its end near South Georgia. Scientists will be studying its effects on the ecosystem around the island for some time.
