The cost of generating electricity in an Australian grid powered by 82% renewable energy would be a third cheaper than current wholesale electricity costs, according to new CSIRO analysis.
The organisation has for the first time modelled the likely cost of electricity generation from different combinations of technology that could make up Australia’s grid in 2030 and 2050. Previous work has only looked at the comparative costs of individual technologies.

In today’s newsletter: As species across the world struggle to keep pace with global warming, how do we report the rare glimmers of hope without downplaying the accelerating ecological crisis?
Good morning. Amid the constant drumbeat of bleak news about the planet’s environment and the accelerating climate emergency, the occasional bright spot still emerges. One example came last week, when researchers published the first statistical evidence that polar bears are changing their DNA in response to a warming Arctic.
But is it really good news that human activity – the burning of fossil fuels and the destruction of habitats – is forcing animals to alter their genetic makeup? The picture, as ever, is complicated.
Donald Trump | Donald Trump has filed a lawsuit against the BBC over its editing of a speech he made to supporters in Washington before they stormed the US Capitol in 2021, requesting at least $5bn in damages.
Australia | Australia’s national security agency Asio investigated one of the alleged Bondi shooters in 2019 over potential extremist links but decided he was not “a person of interest”, prime minister Anthony Albanese has revealed, despite two of the man’s associates being jailed.
International trade | The US has paused its promised multi-billion-pound investment into British tech over trade disagreements, marking a serious setback in US-UK relations.
Health | Resident doctors in England will go on strike as planned this Wednesday for five days, after they voted to reject the government’s latest offer to end the long running pay and jobs dispute.

Launch of third generation of Leaf follows investment of more than £450m into model, including £300m direct to UK
Nissan has started the production of its latest electric car in Sunderland, a crucial step in the UK automotive industry’s transition away from petrol and diesel.
The Japanese manufacturer will launch the third generation of the Leaf on Tuesday, which was the first mass-market battery electric car to be built in the UK. Nissan has made 282,704 Leaf models at the north-east England plant so far.

Climate crisis forecast to wipe out thousands of glaciers a year globally, threatening water supplies and cultural heritage
Europe live – latest updates
Glaciers in the European Alps are likely to reach their peak rate of extinction in only eight years, according to a study, with more than 100 due to melt away permanently by 2033. Glaciers in the western US and Canada are forecast to reach their peak year of loss less than a decade later, with more than 800 disappearing each year by then.
The melting of glaciers driven by human-caused global heating is one of the clearest signs of the climate crisis. Communities around the world have already held funeral ceremonies for lost glaciers, and a Global Glacier Casualty List records the names and histories of those that have vanished.

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.
