Fish levels fall by 7.2% with as little as 0.1C of warming per decade, northern hemisphere research shows
Chronic ocean heating is fuelling a “staggering and deeply concerning” loss of marine life, a study has found, with fish levels falling by 7.2% from as little as 0.1C of warming per decade.
Researchers examined the year-to-year change of 33,000 populations in the northern hemisphere between 1993 and 2021, and isolated the effect of the decadal rate of seabed warming from short shifts such as marine heatwaves. They found the drop in biomass from chronic heating to be as high as 19.8% in a single year.

Researchers say solitary bottlenose has adapted well to city waters, but tighter controls on boat traffic and human behaviour are needed
Italian scientists monitoring the movements of a dolphin in the Venice lagoon have said humans are the ones who need managing, rather than wildlife.
Known as Mimmo, the bottlenose dolphin has been spotted on several occasions since it made its first appearance in June last year, prompting a research team from the University of Padova to spring into action.

UK Climate Change Committee voices concern over Scotland’s progress on decarbonising buildings and reliance on unproved technologies
Scotland has finally produced realistic short-term plans on cutting its climate emissions, but there is “real concern” about the credibility of its overall strategy, the UK’s climate policy watchdog has found.
Nigel Topping, the chair of the UK Climate Change Committee, said there were “flashing amber lights” about the quality and seriousness of some of the Scottish government’s medium- and long-term proposals to reach net zero by 2045.

Critics say proposal to fold department into a new ‘mega ministry’ will dilute accountability and put nature protections at risk

Under the plan, the department would be folded into a new “mega-ministry” that will cover housing, urban development, transport, local government and the environment.

For Immediate Release October 19, 2023
Sedgwick, Maine USA World Ocean Explorer, a 3D virtual aquarium and educational simulation, was recently cited for excellence, winning a Gold Medal Award in the 2023 International Serious Play Awards Program.
World Ocean Explorer is an innovative 3D virtual aquarium designed for educational exploration of the world’s oceans. With interactive exhibits and a lobby space, visitors can immerse themselves in realistic marine environments, including a DEEP SEA exhibit funded by Schmidt Ocean Institute, showcasing unprecedented deep-sea discoveries off Australia. Targeted at 3rd graders and beyond, this immersive experience offers a range of perspectives on the ocean environment and can be explored through guided tours or user-controlled interfaces. Visit DEEP SEA at worldoceanexplorer.org/deep-sea-aquarium.html.
Serious Play Conference brings together professionals who are exploring the use of game-based learning, sharing their experience, and working together to shape the future of training and education.

World Ocean Explorer is a transformative virtual aquarium designed to deepen understanding of the world ocean and amplify connection for young people worldwide. Organized around the principles of Ocean Literacy and the Next Gen Science Standards, World Ocean Explorer brings the wonder and knowledge of ocean species and systems to students in formal and informal classrooms, absolutely free to anyone with a good Internet connection. As an advocate for the ocean through communications, World Ocean Observatory believes there is no better investment in the future of the sustainable ocean than through a new approach to educational engagement that excites, informs, and motivates students to explore the wonders of our marine world and to understand the pervasive connection and implication for our future, inherent in the protection and conservation of all aspects of our ocean world.
World Ocean Explorer presents an astonishing 3-dimensional simulated aquarium visit, organized to reveal the wonders of undersea life, with layers of detailed data and information to augment the emotional connection made to the astonishing beauty and complexity of the dynamic ocean. Within each of the virtual exhibits, students visit exemplary theme-based sites with myriad opportunities to understand the larger perspectives of scientific knowledge as organized and visualized to dramatize the impact and change on ocean life as a result of natural and human-generated events. Through immersion among displays, mixed media and 3D models, the experience of an aquarium visit will be brought into classrooms or home school environments as a free, accessible, always available opportunity for teaching and learning. All of this will be available to a world audience without physical limitation or cost. World Ocean Explorer, a project of the World Ocean Observatory, receives support from the Seth Sprague Educational and Charitable Foundation, Visual Solutions Lab, the Climate Change Institute, the Khaled bin Sultan Living Oceans Foundation, and The Fram Museum Oslo.
