Sharks and rays have populated the world's oceans for around 450 million years, but more than a third of the species living today are severely threatened by overfishing and the loss of their habitat. Palaeobiologists have now investigated whether and how global warming influences the diversity of sharks based on climate fluctuations between 200 and 66 million years ago. According to the study, higher temperatures and more shallow water areas have a positive effect, while higher CO2 levels have a clearly negative effect.

The productivity of cacao trees decreases with time, forcing farmers to renew their plantations by either cutting down the old trees or establishing a new crop elsewhere. Frequently, new plantations are established in areas of the forest that are thinned out to accommodate new, young cacao trees. However, this comes with high economic and ecological costs. An alternative approach is to graft highly productive and native cultivars onto the existing older cacao trees. An international team found that cacao grafting is a useful measure to rejuvenate cacao plants, increasing their yield and profits with minimal impact on biodiversity.

Officials are making clean-energy moves in California, New York and beyond, and Republican states will be integral too
As the Trump administration rolls back decades-old environmental protections and pulls Biden-era incentives for renewable energy, state-level advocates and officials are preparing to fill the void in climate action.
Some state leaders are preparing to legally challenge the president’s environmental rollbacks, while others are testifying against them in Congress. Meanwhile, advocates are pushing for states to meet their ambitious climate goals using methods and technologies that don’t require federal support.

Road outside high court blocked in protest at ‘draconian’ sentences given to 16 Just Stop Oil ‘political prisoners’
Hundreds of protesters have blocked the road outside the high court in London, where the appeals of 16 jailed climate activists are being heard, in condemnation of “the corruption of democracy and the rule of law”.
As England’s most senior judge heard arguments in the appeal of the sentences of the Just Stop Oil activists, who are serving a combined 41 years in jail, their supporters sat on the road in silence holding placards proclaiming them “political prisoners”.

While the US president seems hellbent on securing Greenland, local experts believe that controlling the potentially lucrative shipping route will be no mean feat
If shipping boss Niels Clemensen were to offer any advice to Donald Trump or anyone else trying to get a foothold in Greenland, it would be this: “Come up here and see what you are actually dealing with.”
Sitting on the top floor of his beamed office in Nuuk harbour, where snow is being flung around by strong winds in the mid-morning darkness outside and shards of ice pass by in the fast-flowing water, the chief executive of Greenland’s only shipping company, Royal Arctic Line, says: “What you normally see as easy [setting up operations] in the US or Europe is not the same up here.” As well as the cold, ice and extremely rough seas, the world’s biggest island does not have a big road network or trains, meaning everything has to be transported either by sea or air. “I’m not saying that it’s not possible. But it’s going to cost a lot of money.”

Court says UK government green light for Rosebank and Jackdaw permits does not take into account CO2 emissions
The decision to greenlight a giant new oilfield off Shetland has been ruled unlawful by the courts, in a major win for climate action that scientists say is urgently needed.
The proposed Rosebank development – the UK’s biggest untapped oilfield – had been given the go-ahead in 2023 under the previous government.

Q: The Ryanair boss Michael O’Leary says you are wrong, and the third runway won’t be built until you are 70. You are 45 now. Why is he wrong?
We’re signing off decisions on wind farms, on solar farms, a commitment to a new stadium at Old Trafford. We are upgrading the Transpennine route to make journey times easier between York and Manchester via Leeds and Huddersfield. Those things are happening right now.

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.
