  • A Hellish 'Hothouse Earth' Getting Closer, Scientists Say
    by msmash on 11/02/2026 at 9:00 pm

    The world is closer than thought to a "point of no return" after which runaway global heating cannot be stopped, scientists have said. From a report: Continued global heating could trigger climate tipping points, leading to a cascade of further tipping points and feedback loops, they said. This would lock the world into a new and hellish "hothouse Earth" climate far worse than the 2-3C temperature rise the world is on track to reach. The climate would also be very different to the benign conditions of the past 11,000 years, during which the whole of human civilisation developed. At just 1.3C of global heating in recent years, extreme weather is already taking lives and destroying livelihoods across the globe. At 3-4C, "the economy and society will cease to function as we know it," scientists said last week, but a hothouse Earth would be even more fiery. The public and politicians were largely unaware of the risk of passing the point of no return, the researchers said. The group said they were issuing their warning because while rapid and immediate cuts to fossil fuel burning were challenging, reversing course was likely to be impossible once on the path to a hothouse Earth, even if emissions were eventually slashed. It was difficult to predict when climate tipping points would be triggered, making precaution vital, said Dr Christopher Wolf, a scientist at Terrestrial Ecosystems Research Associates in the US. Wolf is a member of a study team that includes Prof Johan Rockstrom at the Potsdam Institute for Climate Impact Research in Germany and Prof Hans Joachim Schellnhuber at the International Institute for Applied Systems Analysis in Austria.

  • US Had Almost No Job Growth in 2025
    by msmash on 11/02/2026 at 8:01 pm

    An anonymous reader shares a report: The U.S. economy experienced almost zero job growth in 2025, according to revised federal data. On a more encouraging note: hiring has picked up in 2026. Preliminary data had indicated that the U.S. economy added 584,000 jobs last year. But the Bureau of Labor Statistics revised that number after it received additional state data, and found that the labor market had added 181,000 jobs in all of 2025. This is far fewer than the 1.46 million jobs that were added in 2024. One bright spot was last month, when hiring increased by 130,000 roles. This was significantly more than the 55,000 additions that had been expected by economists. "Job gains occurred in health care, social assistance, and construction, while federal government and financial activities lost jobs," BLS said in a statement. Read more of this story at Slashdot.

  • EVs Could Be Cheaper To Own Than Gas Cars in Africa by 2040
    by msmash on 11/02/2026 at 7:00 pm

    Electric vehicles accounted for just 1% of new car sales across Africa in 2025, but a study published in Nature Energy by researchers at ETH Zurich finds that EVs paired with solar off-grid charging systems -- solar panels, batteries and an inverter -- could become cheaper to own than gas-powered equivalents across most of the continent by 2040. The analysis considered total cost of ownership including sticker price, financing and fuel or charging costs, but excluded policy-related factors like taxes and subsidies. Electric two-wheelers could reach cost parity even sooner, by the end of the decade, thanks to smaller battery packs. Small cars remain the toughest segment. The biggest obstacle is financing: in some African countries, political instability and economic uncertainty push borrowing costs so high that interest on an EV loan can exceed the vehicle's purchase price. South Africa, Mauritius and Botswana are already near the financing conditions needed for cost parity; countries like Sudan and Ghana would need drastic cuts. Read more of this story at Slashdot.

  • UK Orders Deletion of Country's Largest Court Reporting Archive
    by msmash on 11/02/2026 at 6:01 pm

    The UK's Ministry of Justice has ordered the deletion of the country's largest court reporting archive [non-paywalled source], a database built by data analysis company Courtsdesk that more than 1,500 journalists across 39 media organizations have used since the lord chancellor approved the project in 2021. Courtsdesk's research found that journalists received no advance notice of 1.6 million criminal hearings, that court case listings were accurate on just 4.2% of sitting days, and that half a million weekend cases were heard without any press notification. In November, HM Courts and Tribunal Service issued a cessation notice citing "unauthorized sharing" of court data based on a test feature. Courtsdesk says it wrote 16 times asking for dialogue and requested a referral to the Information Commissioner's Office; no referral was made. The government issued a final refusal last week, and the archive must now be deleted within days. Chris Philp, the former justice minister who approved the pilot and now shadow home secretary, has written to courts minister Sarah Sackman demanding the decision be reversed.

  • Are CDs Making a Comeback? A Statistical Analysis
    by msmash on 11/02/2026 at 5:00 pm

    Reports of the compact disc's death may have been slightly premature, according to a new analysis from Stat Significant that finds CD sales as a share of U.S. music industry revenue have quietly stabilized after years of steep decline. RIAA data shows CD revenue share fell from 7.15% in 2018 to 3.04% in 2022 but has since flatlined at roughly 3%, coming in at 3.14% in 2023 and 3.06% in 2024. Google search traffic for "CD Player" has ticked upward over the past 16 months after two decades of near-continuous decline, and a May 2023 YouGov poll found 53% of American adults willing to pay for music on CDs -- ahead of vinyl at 44% and online streaming at 50%. Respondents under 45 were more likely to express interest in buying physical formats than older cohorts. But on the supply side, Discogs data shows vinyl remains the dominant format for new physical releases; artists have not meaningfully shifted back toward CD production.

  • HP Now Rents Gaming Laptops
    by msmash on 11/02/2026 at 4:00 pm

    HP has quietly launched a gaming laptop subscription service called the OMEN Gaming Subscription that lets customers pay a monthly fee to use one of several gaming laptops but never actually own the hardware, even after paying well past the machine's retail price. The service ranges from $50 a month for an HP Victus 15-inch laptop with an RTX 4050 to $130 a month for an Omen Max 16 with an RTX 5080. At current sale prices, subscribers would exceed the cost of buying the laptop outright within 16 to 19 months; at MSRP, that window stretches to roughly 25 months. In exchange for giving up ownership, subscribers get yearly hardware upgrades, next-day replacements, 24/7 support, and an ongoing warranty. There is a 30-day trial period, but cancelling in the second month triggers steep early termination fees -- $550 for the Victus 15 and $1,430 for the Omen Max 16. Cancellation becomes free only after the 13th month. HP also offers accessories like the HyperX Cloud Alpha Wireless headset as add-on rentals for $8 a month. Read more of this story at Slashdot.
