Nearly every indicator of climate change is flashing red. But we still hold the tools available to bring the planet back into balance
The ocean is running a fever. In 2025, the number of days of marine heatwaves – prolonged spells when the sea turns abnormally, dangerously warm – was more than triple what it was in the early 1990s.
These are not abstract statistics. A severe and persistent marine heatwave bleaches coral reefs, strips away the kelp forests that shelter young fish, empties fishing grounds and – if occurring frequently – can tip whole ecosystems past the point of recovery.

Global warming threatens to eradicate Earth’s tropical corals. As legal interventions addressing climate change expand, fossil fuel companies’ historical awareness of their products’ damaging effects is increasingly important. We searched historical documents using a large-language-model-based agent, finding that carbon majors were aware by the 1980s of prospective impacts of fossil fuels on corals from ocean acidification, marine heatwaves, sea-level rise, and intensified storms and later funded efforts downplaying such impacts.

The future of global ocean observations: five scenarios

It used to be easier to say that the chances of a shark attack were slim. Now I feel as though that pretence of safety has been shattered
After nearly a year’s break, I started ocean swimming again this May, delighting in the clarity of the water and the quieter beaches of Sydney’s winter. I’d stopped because of an injury but then found that the longer I was out of the water the harder it was to get back in.
It only took that first return swim, however, to remember the absolute euphoria of winter ocean swimming. Part of it is the cold water, how alive it makes you feel, and part is the wildness of it: seeing the variety of underwater marine life, the distant spray of a migratory whale. It is utterly different from swimming laps in a pool.

Justice department urges judge to throw out suit brought by NAACP over xAI’s methane-gas turbines in Mississippi
The Trump administration is coming to the defense of Elon Musk in a lawsuit over claims that his artificial intelligence company, xAI, is polluting residential neighborhoods in north Mississippi. The justice department told a federal court late on Monday to throw out the case.
The lawsuit was filed by the NAACP in April over allegations that xAI and its subsidiary MZX Tech set up dozens of methane-gas turbines to power its datacenter in Southaven, Mississippi, without air permits. The suit claims these turbines emit toxic pollutants in violation of the Clean Air Act, and is asking a judge to block xAI from operating the machines.

It is still not totally clear what the government wants but the political mood seems to be shifting towards a decision
Thames Water nationalisation moves closer as government objects to rescue deal
At last, Emma Reynolds, the environment secretary, has opined on the future of Thames Water. So what’s it to be? A takeover by the company’s creditors? Special administration, which would allow anyone to pitch up with an offer while the state temporarily funds the company? Or even a quick flush to full nationalisation?
Well, two years after Thames’s shareholders walked away, and 18 months after the creditors opened talks with regulator Ofwat on the terms on a potential recapitalisation, one still can’t say definitively what the government wants. But we do have a better idea: the political mood seems to be shifting firmly towards administration.

Lisa Murkowski, a Republican senator, joins Democrats in bid to stop dismantling of Ocean Observatories Initiative
US politics live – latest updates
A group of Democratic senators and one Republican, as well as two Democratic House committees, sent letters on Monday to the National Science Foundation asking it to reverse course on its plan to dismantle a sprawling ocean monitoring network, with House lawmakers going further and accusing the agency of acting illegally.
The Ocean Observatories Initiative is a network of more than 900 ocean sensors built at a cost of $386m. Over the last decade it has tracked ocean circulation, marine ecosystems, climate change and extreme weather, producing data freely available to the public and informing more than 500 scientific publications. The project was slated to run another 15 to 20 years.

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.
