UK funds geoengineering experiments as global controversy grows
As temperatures fall and sunlight wanes this winter, scientists will gather in the Canadian Arctic with drills and pumps in tow. Their mission: to refreeze the region's melting sea ice.
Known as Re-Thickening Arctic Sea Ice, or RASi, the project aims to pump seawater from the ocean and spray it over the top of existing ice floes, where the cold air will freeze it solid. Researchers hope that the process will create a thicker layer of sea ice, helping undo some of the damage caused by rising global temperatures.
For now, it's just an experiment — and a relatively small one at that. Over the next three winter seasons, the researchers plan to refreeze areas as large as 1 square kilometer, or 0.38 square miles. Along the way, they'll assess how the project affects the local ecology and the movement of the sea ice — and how long it takes to melt again in the summer.

The project is one of a handful of geoengineering experiments funded by the British government. UK's Advanced Research and Invention Agency (ARIA) announced on Wednesday that it would invest a total of about $60 million in climate-cooling research, spread among 21 projects.

Film Festival showcases what artificial intelligence can do on the big screen
NEW YORK (AP) — Artificial intelligence 's use in movie making is exploding. And a young film festival, now in its junior year, is showcasing what this technology can do on screen today. The annual AI Film Festival organized by Runway, a company that specializes in AI-generated video, kicked off in New York Thursday night with ten short films from around the world making their debut on the big screen. 'Three years ago, this was such a crazy idea,' Runway CEO Cristóbal Valenzuela told the crowd. 'Today, millions of people are making billions of videos using tools we only dreamed of.' The film festival itself has grown significantly since its 2023 debut. About 300 people submitted films when it first began, Valenzuela said, compared to about 6,000 submissions received this year. The one and half-hour lineup stretched across a range of creative styles and ambitious themes — with Jacob Alder's ' Total Pixel Space " taking home the festival's top prize. The 9-minute and 28-second film questions how many possible images — real or not — exist in the digital space, and uses math to calculate a colossal number. A stunning series of images, ranging from the familiar life moments to those that completely bend reality, gives viewers a glimpse of what's out there. Meanwhile, Andrew Salter's 'Jailbird,' which snagged second place, chronicles a chicken's journey — from the bird's perspective — to a human prison in the United Kingdom to take part in a joint-rehabilitation program. And 'One,' a futuristic story by Ricardo Villavicencio and Edward Saatchi about interplanetary travel followed in third place. The 10 films shown were finalists selected from thousands submitted to Runway's AI Film Festival this year. The shorts will also be shown at screenings held in Los Angeles and Paris next week. How AI is used and executed is a factor judges evaluate when determining festival winners. But not every film entered was made entirely using AI. While submission criteria requires each movie include the use of AI-generated video, there's no set threshold, meaning some films can take a more 'mixed media' approach — such as combining live shots of actors or real-life images and sounds with AI-generated elements. 'We're trying to encourage people to explore and experiment with it,' Valenzuela said in an interview prior to Thursday's screening. Creating a coherent film using generative AI is no easy feat. It can take a long list of directions and numerous, detailed prompts to get even a short scene to make sense and look consistent. Still, the scope of what this kind of technology can do has grown significantly since Runway's first AI Film Festival in 2023 — and Valenzuela says that's reflected in today's submissions. While there are still limits, AI-generated video is becoming more and more life-like and realistic. Runway encourages the use of its own AI tools for films entered into its festival, but creators are also allowed to turn to other resources and tools as they put together the films — and across the industry, tools that use AI to create videos spanning from text, image and/or audio prompts have rapidly improved over recent years, while becoming increasingly available. 'The way (this technology) has lived within film and media culture, and pop culture, has really accelerated,' said Joshua Glick, an associate professor of film and electronic arts at Bard College. He adds that Runway's film fest, which is among a handful of showcases aimed at spotlighting AI's creative capabilities, arrives as companies in this space are searching for heightened 'legitimacy and recognition' for the tools they are creating — with aims to cement partnerships in Hollywood as a result. AI's presence in Hollywood is already far-reaching, and perhaps more expansive than many moviegoers realize. Beyond 'headline-grabbing' (and at times controversial) applications that big-budget films have done to 'de-age' actors or create eye-catching stunts, Glick notes, this technology is often incorporated in an array of post-production editing, digital touch-ups and additional behind-the-scenes work like sorting footage. Industry executives repeatedly point to how AI can improve efficiency in the movie making process — allowing creatives to perform a task that once took hours, for example, in a matter of minutes — and foster further innovation. Still, AI's rapid growth and adoption has also heightened anxieties around the burgeoning technology — notably its implications for workers. The International Alliance of Theatrical Stage Employees — which represents behind-the-scenes entertainment workers in the U.S. and Canada — has 'long embraced new technologies that enhance storytelling,' Vanessa Holtgrewe, IATSE's international vice president, said in an emailed statement. 'But we've also been clear: AI must not be used to undermine workers' rights or livelihoods.' IATSE and other unions have continued to meet with major studios and establish provisions in efforts to provide guardrails around the use of AI. The Screen Actors Guild-American Federation of Television and Radio Artists has also been vocal about AI protections for its members, a key sticking point in recent labor actions. For Runway's AI Film Festival, Valenzuela hopes screening films that incorporate AI-generated video can showcase what's possible — and how he says this technology can help, not hurt, creatives in the work they do today. 'It's natural to fear change ... (But) it's important to understand what you can do with it,' Valenzuela said. Even filmmaking, he adds, was born 'because of scientific breakthroughs that at the time were very uncomfortable for many people.'

Elon Musk pulls back on threat to withdraw Dragon spacecraft
As President Donald Trump and Elon Musk argued on social media on Thursday, the world's richest man threatened to decommission a space capsule used to take astronauts and supplies to the International Space Station. A few hours later, Musk said he wouldn't follow through on the threat. After Trump threatened to cut government contracts given to Musk's SpaceX rocket company and his Starlink internet satellite services, Musk responded via X that SpaceX 'will begin decommissioning its Dragon spacecraft immediately.' It was unclear how serious Musk's threat was, but several hours later — in a reply to another X user — he said he wouldn't do it. The capsule, developed with the help of government contracts, is an important part of keeping the space station running. NASA also relies heavily on SpaceX for other programs including launching science missions and, later this decade, returning astronauts to the surface of the moon. The Dragon capsule SpaceX is the only U.S. company capable right now of transporting crews to and from the space station, using its four-person Dragon capsules. Boeing's Starliner capsule has flown astronauts only once; last year's test flight went so badly that the two NASA astronauts had to hitch a ride back to Earth via SpaceX in March, more than nine months after launching last June. Starliner remains grounded as NASA decides whether to go with another test flight with cargo, rather than a crew. SpaceX also uses a Dragon capsule for its own privately run missions. The next one of those is due to fly next week on a trip chartered by Axiom Space, a Houston company. Cargo versions of the Dragon capsule are also used to ferry food and other supplies to the orbiting lab. NASA's other option: Russia Russia's Soyuz capsules are the only other means of getting crews to the space station right now. The Soyuz capsules hold three people at a time. For now, each Soyuz launch carries two Russians and one NASA astronaut, and each SpaceX launch has one Russian on board under a barter system. That way, in an emergency requiring a capsule to return, there is always someone from the U.S. and Russia on board. With its first crew launch for NASA in 2020 — the first orbital flight of a crew by a private company — SpaceX enabled NASA to reduce its reliance on Russia for crew transport. The Russian flights had been costing the U.S. tens of millions of dollars per seat, for years. NASA has also used Russian spacecraft for cargo, along with U.S. contractor Northrup Grumman. SpaceX's other government launches The company has used its rockets to launch several science missions for NASA as well as military equipment. Last year, SpaceX also won a NASA contract to help bring the space station out of orbit when it is no longer usable. SpaceX's Starship mega rocket is what NASA has picked to get astronauts from lunar orbit to the surface of the moon, at least for the first two landing missions. Starship made its ninth test flight last week from Texas, but tumbled out of control and broke apart.

Collapsing Forest Eco-Systems Could Destabilize Economies, Study Finds
EUREKA, CALIFORNIA - DECEMBER 19 : Barren hillsides on forest lands near Headwaters Forest (CA) are ... More stripped of trees and harvested by loggers, December 19, 1998 in Eureka, California. (Photo by Getty Images/Bob Riha, Jr.) The collapse of forest ecosystems could destabilise societies and economies around the globe, according to a new analysis. The study by the International Union of Forest Research Organizations (IUFRO) highlights the role of forests in upholding and enhancing the resilience of social and economic systems. But it warns many forests are being pushed to the brink of collapse, which could send ripple effects across the globe, destabilising societies and economies, and it adds they simply cannot be 'put back together again' afterwards. The report also warns the world's forests are not immune to global political and socio-economic shifts. It argues as political polarisation grows, and climate change is becoming less of a priority, markets are shifting and changing the way in which forests are being managed. The study also calls on policymakers to recognise that forests are not isolated systems but instead exist as social-ecological systems. It also adds forests can contribute to social well-being by improving public health, community cohesion, and quality of life. 'Urban forests are invaluable assets for economic resilience, offering both direct and indirect benefits to urban dwellers, and others,' the report states. 'From an economic standpoint, urban trees have been shown to increase property values and attract businesses and tourists.' Dr. Craig Allen, from the School of Natural Resources at the University of Nebraska–Lincoln, said forests around the world are under pressure in an interview. Dr. Allen said in some countries forest land is being lost to agriculture, urbanization or wildfires, which can have a direct impact on both the eco-systems around them and the people who rely on them for their livelihoods. 'The economic impacts of forests are enormous,' he told me. 'If your forest ecosystem collapses, there are going to be knock-on effects to society 'These range from timber products to carbon sequestration. And when we lose forest after forest, the impact scales up to further exacerbate the pace of global change. 'It's critically important not to allow those collapses to happen, because we do not really know how to restore functioning, complex forest eco-systems.' Dr. Nelson Grima, coordinator of the science-policy programme at IUFRO said when we destabilise forests, the impacts can be felt across all regions and economies in a statement. Dr. Grima added every person relies on forests to either regulate their climate, sequester carbon, or to alleviate poverty, ensure food and clean water or to keep economies stable. The report comes as American Forests, in partnership with the UCLA Luskin Center for Innovation, launches a new shade map, which maps the shade infrastructure for some of the largest urbanized areas in more than 360 cities and towns. The map aims to help decision-makers identify existing shade deserts and prioritize investments in trees and engineered shade solutions to mitigate the impacts of extreme heat. It is part of American Forests' national movement to advance tree equity, ensuring that every neighborhood has access to the life-saving benefits of trees. American Forests' senior director of data, design and UX, Julia Twichell said on average, trees deliver 25 times more shade than buildings in U.S. cities at noon when the sun is directly overhead in a statement. Prof. Kelly Turner, at associate director at UCLA Luskin Center for Innovation, said shade is one of the most effective tools there is to cool people when they are outside in an interview. Prof. Turner added shade provided by trees can be stable throughout the day, while shade provided by buildings can vary depending on what time it is. 'Tree shade can also provide additional benefits, which building shade cannot, like ecological, psychological and mental health benefits,' said Professor Turner.
