L’Arctic-Metagaz, un navire sous sanction rempli de gaz naturel liquéfié, dérive dangereusement depuis que son remorquage par les autorités libyennes a échoué.

Vanaf vanavond kan je kijken naar '2050', een documentairereeks over de klimaatopwarming waarin Eric Goens ons meeneemt naar Antarctica. We zien hoe het zuidpoolgebied de perfecte graadmeter is voor de veranderingen op onze planeet die volop aan het gebeuren zijn, met een steeds sneller tempo.
Très endommagé par un drone naval, l’« Arctic-Metagaz » dérive depuis deux semaines au large de la Sicile sans qu’une décision soit prise pour prévenir une pollution grave.
Le ministère russe des Affaires étrangères a demandé aux pays situés à proximité d'un méthanier dérivant en Méditerranée de prendre leurs responsabilités afin de prévenir une catastrophe écologique.
Face à la baisse des prises et à la pression des chalutiers industriels, des pêcheurs gambiens se forment en mer pour surveiller et dénoncer les pratiques illégales qui menacent leur avenir. Vert a assisté à l’une de ces formations à bord d’un navire de Greenpeace, l’Arctic Sunrise. On vous embarque.

Welcome to the Global Climate Highlights 2025 report, compiled by the Copernicus Climate Change Service (C3S). The Global Climate Highlights 2025 report provides authoritative climate data and concise insight on a global scale about 2025's climate conditions, covering surface and sea surface temperature, heat stress, sea ice extent in the Arctic and Antarctic, among others.

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.

A “pushing and triggering” mechanism has has driven the Arctic climate system to a new state, which will likely see consistently increased frequency and intensity of extreme events across the atmosphere, ocean and cryosphere this century.
Researchers have discovered dozens of new methane seeps littering the ocean floor in the Ross Sea coastal region of Antarctica, raising concerns of an unknown positive climate feedback loop that could accelerate global warming.

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?
For decades, the surface of the polar Southern Ocean (south of 50°S) has been freshening—an expected response to a warming climate. This freshening enhanced upper-ocean stratification, reducing the upward transport of subsurface heat and possibly contributing to sea ice expansion. It also limited the formation of open-ocean polynyas. Using satellite observations, we reveal a marked increase in surface salinity across the circumpolar Southern Ocean since 2015. This shift has weakened upper-ocean stratification, coinciding with a dramatic decline in Antarctic sea ice coverage. Additionally, rising salinity facilitated the reemergence of the Maud Rise polynya in the Weddell Sea, a phenomenon last observed in the mid-1970s.

Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehend
The West Antarctic Ice Sheet could reach its tipping point with only minimal additional ocean warming – with long-term consequences for global sea levels. But a small window of time remains to take countermeasures.

Le ministre de l’intérieur américain a notamment annoncé le rétablissement d’un programme permettant d’exploiter le pétrole et le gaz dans l’ensemble de l’Arctic National Wildlife Refuge, une aire protégée qui s’étend sur plus de 630 000 hectares.
Antarctica's remote and mysterious current has a profound influence on the climate, food systems and Antarctic ecosystems. Can we stop it weakening by 2050?
The Antarctic Circumpolar Current (ACC) is the world's strongest ocean current and plays a disproportionate role in the climate system due to its role as a conduit for major ocean basins. This current system is linked to the ocean's vertical overturning circulation, and is thus pivotal to the uptake of heat and CO2 in the ocean. The strength of the ACC has varied substantially across warm and cold climates in Earth's past, but the exact dynamical drivers of this change remain elusive. This is in part because ocean models have historically been unable to adequately resolve the small-scale processes that control current strength. Here, we assess a global ocean model simulation which resolves such processes to diagnose the impact of changing thermal, haline and wind conditions on the strength of the ACC. Our results show that, by 2050, the strength of the ACC declines by ∼20% for a high-emissions scenario. This decline is driven by meltwater from ice shelves around Antarctica, which is exported to lower latit
