La veille

A la veille de la conférence de l’ONU sur l’océan qui se tient à Nice, un comité de scientifiques internationaux dévoile ce dimanche 8 juin un rapport inédit sur l’état de santé des océans.

Have you ever thought about what would happen if all life in the ocean disappeared? A recent study explores this extreme scenario to understand how ocean biology shapes the past, present, and future climate. The ocean plays a critical role in regulating Earth's climate. It is a massive carbon store that absorbs about 25% of human-caused emissions and thus helps maintain a relatively low CO2 level in the atmosphere. But what would happen if all marine life—from the tiniest plankton to the largest whales—disappeared? A recent study delves into this extreme scenario to uncover the crucial role that ocean biology plays in mitigating climate change.

‘Catastrophic’ global decline due to dams, mining, diverting water and pollution threatens humans and ecosystems, study warns

The law will come into force in national parks within two years and in all of the country’s marine protected areas by 2030

Vladimir Poutine a entériné, lundi 11 mars, la dénonciation de l’accord permettant depuis 1956 aux pêcheurs du Royaume-Uni d’opérer dans les eaux russes de la mer de Barents. Or, comme le pointe la presse, plusieurs centaines de milliers de tonnes de cabillaud ont été puisées par les Britanniques dans la région arctique l’an dernier.

A chemical that takes thousands of years to break down is found in England's freshwater fish at 1,000 times above safe levels – and could end up on our dinner tables

We are a species that is superb at killing, says veteran oceanographer, who calls for us to stop treating fish like crops and give them the respect they deserve

L'Ouganda a lancé mardi ses premières activités de forage dans les champs pétroliers de Kingfisher, au lac Albert, accédant ainsi au rang de producteur de brut avec un mégaprojet critiqué par les défenseurs de l'environnement. Le président Yoweri Museveni a lancé "le début de la campagne de forage sur le champ pétrolier de Kingfisher (dans l'ouest de l'Ouganda, ndlr) qui devrait produire 40 000 barils de pétrole par jour" en 2025, a annoncé sur Twitter l'autorité ougandaise du pétrole.

A community of Indigenous peoples worried that mercury used by gold miners was contaminating the fish they eat. So they created a DIY team to find out more.

Lost nets, lines and hooks trap wildlife for years as they float in the ocean, sink to the bottom or are washed ashore

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as food waste reduction would have limited impact on increasing available calories. We estimate more than 2 billion people could die from nuclear war between India and Pakistan, and more than 5 billion could die from a war between the United States and Russia—underlining the importance of global cooperation in preventing nuclear war.

Restaurant menus across the West Coast of Canada will soon see an influx of squid and sardine dishes, while the popular sockeye salmon makes a slow exit. As it turns out, climate change may have something to do with this.

Activisten van Ocean Rebellion hielden gisteren (zondag) een last minute pleidooi voor de EU-ministers om het mariene ecosysteem te redden. Drie activisten hadden pakken aan en vismaskers op die dropen van het bloed en de ingewanden, twee andere activisten waren verkleed als vissers. De drie 'vissenkoppen' stonden in plassen bloed en dode vissen voor het Berlaymontgebouw van de Europese Commissie. Ze droegen koffers met de slogans 'WAR ON FISH', 'ECOCIDE' en 'END OVERFISHING'.

The ivory-billed woodpecker, along with 22 other species of birds, fish, mussels and other wildlife, is set to be declared extinct and removed from the endangered species list, US federal wildlife officials announced Wednesday.

The world’s coral reef cover has halved since the 1950s, ravaged by global heating, overfishing, pollution and habitat destruction, according to an analysis of thousands of reef surveys. From the 1,430-mile (2,300km) Great Barrier Reef in Australia to the Saya de Malha Bank in the Indian Ocean, coral reefs and the diversity of fish species they support are in steep decline, a trend that is projected to continue as the planet continues to heat in the 21st century.
