The first comprehensive assessment of trends in Southern Ocean ecosystems reveals an urgent need to address climate change. The summary for policymakers can guide decision-makers.
"The #oceans absorb 90% of the heat trapped by the #CarbonEmissions from the burning of fossil fuels, making it the clearest indicator of global heating.
The ocean surface temperatures in 2023 were “off the charts”, the researchers said. The primary cause was another year of record carbon emissions, assisted by El Niño. Over the whole year, the average temperature was 0.1C above 2022, but in the second half of 2023 the temperature was an “astounding” 0.3C higher."
Can I get some follow recommendations? I’m acutely aware that of the people I follow who post about our planet’s systems, most of them are climate people. I’d love to follow more people posting at a #systems level. Y’know, the people who distill down expert knowledge into consumable packets for the rest of us. Think #hydrology/ #freshwater/ #oceans, #biodiversity, #ecology, #biology, #agriculture, #energy, #economics, #geology#planetaryBoundaries … these kind of topics. Boosts appreciated!
ABOLISH SEISMIC BLASTING SPECIAL PROSPECTING AUTHORITY PERMITS (SPA)
A Special Prospecting Authority (SPA) is a specific type of permit that allows #companies to buy access to large areas of our #oceans to use #SeismicBlasting to search for #oil and #gas, and Carbon Capture and Storage locations below the ocean floor.
Seismic blasts are how the oil and gas industry surveys the ocean floor. Seismic vessels tow an array of airguns and audio receivers (hydrophones) behind them in the water.
Sous les falaises d'Étretat, la montée des eaux entraîne des déchets vers la mer https://reporterre.net/Sous-les-falaises-d-Etretat-la-montee-des-eaux-entraine-des-dechets-vers-la-mer
Pendant près d'un demi-siècle, des tonnes de déchets ont été jetées du haut de la falaise, près du Havre. Avec la montée du niveau de la mer, ces remblais d'ordures s'effondrent peu à peu dans la mer.

For years, great white sharks had been swimming off the shores of South Africa. Then, the creatures often turned up dead in the country’s beaches missing something critical — their livers. Science Alert points out orcas as the culprits, and discusses how the sharks reacted. https://flip.it/.IpSK3 #Science#GreatWhiteShark#Sharks#Oceans#Orca#Whales
With their stealth, speed and serrated teeth, sharks are predators to be reckoned with. And that’s before factoring in the cocaine some sharks may be eating
Earth teemed with life about 530 million years ago in the aftermath of the Cambrian explosion. But something caused a mass extinction of sea life about 20 years later. Was it a lack of oxygen, as past research has suggested? Live Science explores what may have supercharged this “wave of death.” https://flip.it/YrLeW3#Science#Earth#Oceans#Extinction
New research from CSIRO, Australia's national science agency, and the University of Toronto in Canada, estimates up to 11 million metric tons of plastic pollution is sitting on the ocean floor.

OISST provides a real-time daily index of ocean surface temperature (60 S - 60 N). For the last month it has been continuously reading higher than in any previous year and still shows no sign of settling.
Scientists say that coral reefs are currently undergoing a global bleaching event, with more than 54% of the world’s coral reef areas in the territorial waters of over 50 countries experiencing heat stress. According to one scientist, the percentage of areas dealing with bleaching-level heat stress “has been increasing by roughly 1% per week.”
Actual economist in NBER paper: “We find consistent evidence that vessel noise pollution from international shipping has lowered fertility and raised the mortality of the SRKW [Orcas] significantly. Had noise pollution remained at its pre-1998 levels, the SRKW population would be 30% larger. Noise pollution is a growing threat to marine mammals worldwide.” https://www.nber.org/papers/w31390
Norwegian salmon farms are taking huge amounts of wild fish from West Africa, mining the food security of the region, according to a report from the U.K.-based NGO Feedback.

'We invited biologists but they didn’t want to go because they said there’s nothing going on there. We constantly remind them they weren’t there when we made this historic biological discovery; we have to rub it in.’
An overturned vessel has caused a huge oil spill along Trinidad and Tobago’s coastline, in what the Caribbean country’s prime minister described as a “national emergency” on Sunday. The spill occurred on February 7 off the southern shores of the Tobago Island, according to the country’s Office of Disaster Preparedness...
