Drying Lakebeds Are Releasing Massive Amounts of Carbon, Study Finds

3 months 1 week ago
"In many parts of the world, lakes are drying out at a scale so massive that scientists are warning they may be emitting enough greenhouse gases to rival our fossil fuel habit," reports ScienceAlert: In a new study published in Science, scientists say the Aral Sea — the world's largest desiccated lake — has emitted a whopping 204 megatons (~225 million US tons) of carbon dioxide since it was drained in the 1960s... The study estimates that between 1960 and 2022, the evaporating sea has released 204 megatons of carbon dioxide into the atmosphere, based on site surveys and core samples collected from across the dry lakebed... The new study suggests that rehydrating the entire basin could come with enormous benefits to the environment, not just within the sea itself, but at a global level. "There is a hidden carbon treasure beneath the Aral Sea," says biochemist Rafael Marcé from the Spanish National Research Council. "If these sediments remain exposed, carbon will continue to be released into the atmosphere. If the sea is re-flooded, that same carbon could shift from being a source of emissions to becoming part of the climate solution." According to the researchers' calculations, re-flooding the lakebed could prevent the release of the estimated 165 megatons of carbon that remain. The study also revealed that nearly one-fifth of the Aral Sea's carbon emissions are actually being released as wind blows away sediment on the lakebed, a factor that researchers had not accounted for in the past.

Hyundai Claims Humanoid Robot Plan Is Not Part of Talks With Striking Workers

3 months 1 week ago
Ars Technica reports: Hyundai Motor Company's plan to put humanoid robots to work by 2028 is not part of current negotiations with striking South Korean autoworkers, according to the company. The automaker is disputing news reports that partial labor strikes by the Hyundai Motor union at the world's largest automotive plant in South Korea were spurred by concerns about the company's planned deployment of humanoid robots in the United States starting in 2028. [The planned robots are built by Boston Dynamics, now a wholly-owned subsidiary of Hyundai.] A Hyundai statement shared with Ars describes the union's demands as focusing on compensation-related issues such as wage increases, bonuses, and an extension of workers' retirement age. "Potential deployment of robots in Korean production facilities is not part of the current labor-management discussions," according to the Hyundai statement... Hyundai emphasized that its current plan only covers the initial deployment of the Atlas humanoid robot at Metaplant America, an electric vehicle factory near Savannah, Georgia, starting in 2028. "Decisions about future Atlas deployment at other facilities will be made thoughtfully, in accordance with local operational needs, and in dialogue with the employees and workforce representatives at those sites," the company stated. However, The Wall Street Journal described the Hyundai Motor union as making "unprecedented demands seeking to enshrine job protections in the era of robots and AI," and characterized certain compensation demands as hedging against potential reductions in work hours caused by AI adoption and robotic automation. "Remember that without labor-management agreement, not a single robot using new technology will be allowed to enter the workplace," the union told Hyundai in an internal letter reported by Reuters. Hyundai management and the labor union are currently reviewing a proposed wage reform that would "provide factory workers with greater income stability even after the carmaker's planned deployment of humanoid robots," The Korea Times reported. But experts cautioned that the wage overhaul, which would convert hourly pay for overtime and night-shift allowances into fixed wages, could come at the expense of company productivity.

Amazon Cracks Down On Use of AI Images By Sellers

3 months 1 week ago
CNBC reports: Amazon is requiring that third-party sellers label any product images or videos that contain "AI-generated people" after New York recently passed a law mandating greater transparency around "synthetic performers" in ads... The policy directs sellers to tag images [and videos or other graphics on listing pages] with specific metadata keywords before they're uploaded. "Recent legislation requires disclosure when images or videos in advertisements contain photorealistic AI-generated people," Amazon wrote in the announcement [clarifying that the requirement doesn't apply to content featuring TV/video game/movie characters or content including real people, even if they've been altered using AI]. The company said it will "add an indicator" to listings on its website, informing consumers that images or other content feature AI-generated people, "where applicable." It's unclear what criteria Amazon will apply when deciding when to display the label to shoppers... Amazon has embraced AI internally and it's increasingly infusing the technology across its portfolio. The company has optimized listing titles and details so they're more likely to be spotted by AI systems, invested in a recently rebranded assistant called Alexa for Shopping, and launched a feature that injects AI-generated [images of] products into its search bar in real time based on user queries. More Amazon third-party sellers are using AI to generate text, images and other content for their listings, partly by using the company's tools. Outside sellers account for more than 60% of goods sold on Amazon, the article points out. It adds that there's currently no nationwide U.S. law requiring companies to disclose AI-generated advertising content, it adds — but YouTube, Meta, Pinterest, and TikTok have already added labels for AI-generated content. And a new California law also requires large AI providers to embed watermarks in AI-generated images, video and other content...
