ArchieBunker quotes a report from Bloomberg: Texas electricity prices soared almost 100-fold as a high number of power-plant outages raised concerns of a potential evening shortfall. Spot prices at the North Hub, which includes Dallas, jumped to more than $3,000 a megawatt-hour just before 7 p.m. local time, versus about $32 at the same time Tuesday, according to data from the Electric Reliability Council of Texas. This morning, Ercot, as the state's main grid operator is known, issued a "watch" for a potential capacity reserve shortage from about 7-9 p.m., meaning the buffer of spare supplies could fall to low enough levels to call on back-up generation, cancel or delay outages or curb usage.

The conditions are the tightest of the year so far and raises the risk of prices rising to the $5,000 cap -- which they last did on April 16, when Ercot also warned of a potential shortfall. Unusually hot weather in the region has boosted demand for cooling and lowered the efficiency of many power plants. Wind output has also fallen from a day earlier and there are more outages. "Ercot has not called for conservation this evening," it said by email. "The grid is operating under normal conditions at this time."

The world is on the verge of a climate abyss, the UN has warned, in response to a Guardian survey that found that hundreds of the world's foremost climate experts expect global heating to soar past the international target of 1.5C. From a report: A series of leading climate figures have reacted to the findings, saying the deep despair voiced by the scientists must be a renewed wake-up call for urgent and radical action to stop burning fossil fuels and save millions of lives and livelihoods. Some said the 1.5C target was hanging by a thread, but it was not yet inevitable that it would be passed, if an extraordinary change in the pace of climate action could be achieved. The Guardian got the views of almost 400 senior authors of reports by the authoritative Intergovernmental Panel on Climate Change. Almost 80% expected a rise of at least 2.5C above preindustrial levels, a catastrophic level of heating, while only 6% thought it would stay within the 1.5C limit. Many expressed their personal anguish at the lack of climate action.

"The goal of limiting global warming to 1.5C is hanging by a thread," said the official spokesperson for Antonio Guterres, the UN secretary general. "The battle to keep 1.5C alive will be won or lost in the 2020s -- under the watch of political and industry leaders today. They need to realise we are on the verge of the abyss. The science is clear and so are the world's scientists: the stakes for all humanity could not be higher." Alok Sharma, the president of the Cop26 climate summit in 2021, said: "The results of the Guardian's survey should be another wake-up call for governments to stop prevaricating and inject much more urgency into delivering on the climate commitments they have already made." He said world leaders needed to get on and deliver on the pledge they made to transition away from fossil fuels at Cop28 in December.

The largest ever recorded leap in the amount of carbon dioxide laden in the world's atmosphere has just occurred, according to researchers who monitor the relentless accumulation of the primary gas that is heating the planet. From a report: The global average concentration of carbon dioxide in March this year was 4.7 parts per million (or ppm) higher than it it was in March last year, which is a record-breaking increase in CO2 levels over a 12-month period. The increase has been spurred, scientists say, by the periodic El Nino climate event, which has now waned, as well as the ongoing and increasing amounts of greenhouse gases expelled into the atmosphere due to the burning of fossil fuels and deforestation.

"It's really significant to see the pace of the increase over the first four months of this year, which is also a record," said Ralph Keeling, director of the CO2 Program at UC San Diego's Scripps Institution of Oceanography. "We aren't just breaking records in CO2 concentrations, but also the record in how fast it is rising." The global CO2 readings have been taken from a station perched upon the Mauna Loa volcano in Hawaii since the measurements began in 1958 under Keeling's father, Charles. The concentrations of CO2 have increased each year since, as the heat-trapping gas continues to progressively accumulate due to rampant emissions from power plants, cars, trucks and other sources, with last year hitting a new global record in annual emissions.

The North Yorkshire Council in England announced it will ban apostrophes on street signs as it can affect geographical databases. Resident Anne Keywood told the BBC that she urged the authority to retain apostrophes, saying: "If you start losing things like that then everything goes downhill doesn't it?" From the report: North Yorkshire Council said it "along with many others across the country" had opted to "eliminate" the apostrophe from street signs. A spokesperson added: "All punctuation will be considered but avoided where possible because street names and addresses, when stored in databases, must meet the standards (PDF) set out in BS7666.

"This restricts the use of punctuation marks and special characters (e.g. apostrophes, hyphens and ampersands) to avoid potential problems when searching the databases as these characters have specific meanings in computer systems."

A new national survey (PDF) from CNBC/Generation Lab of 1,033 people aged 18 to 34 found that an overwhelming 81% of respondents believe a four-day workweek would boost their company's productivity, while 19% said productivity would decline. CNBC reports: Those results from the "Youth & Money in the USA" survey come amid discussions around the potential benefits of switching from the standard five-day U.S. workweek to a four-day cadence without a pay cut. Some companies have begun testing the arrangement, and say it has mitigated employee burnout and strengthened business performance. Exos, a U.S. coaching company that trains top athletes and leads corporate wellness programs, recently reported results from the first six months of an ongoing four-day workweek experiment. The company said the shortened workweek increased efficiency along with revenue and retention.

Although respondents to the CNBC/Generation Lab survey largely agreed on workweek length, they were less unified when asked about work setting. A 60% majority said they do their best work in the office, while the other 40% said they do so at home. Further reading: 32-Hour Workweek for America Proposed by Senator Bernie Sanders

Librarians are fighting a nationwide battle against high e-book prices, which so far has yielded minimal results. Despite efforts and temporary legislative victories, strict renewal and loan policies imposed by publishers keep e-book costs high, limiting the number of popular titles libraries can offer and leading to frustration among patrons. Axios reports: Publishers typically require libraries to renew the license to each e-book every two years, or after 26 loans -- policies that libraries call prohibitively expensive. This restricts the number of e-books -- particularly popular bestsellers -- that they can lend out to patrons, who are angry and baffled by the limitations. Readers love the free (to them) apps that allow them to borrow countless e-books and audiobooks: Libby (the dominant one, run by OverDrive) and hoopla. But some libraries say that the cost of renewing their contracts with OverDrive and hoopla are prohibitive, so they're dropping the apps -- hoopla in particular.

The Association of American Publishers argues that it must protect the rights of copyright owners -- that is, authors -- to be fairly compensated for their work. hoopla and Libby say they're just the middlemen. "It's really not up to us, to be honest," Ann Ford, a vice president at hoopla, tells Axios. "It's the publishers that make the rules." Libraries have a "unique and determinative public mission" that should entitle them to more favorable e-book purchasing terms when using public funds, says Kyle Courtney, a lawyer and Harvard librarian who drafted model e-book legislation for states.

"These are nonnegotiable contracts, and the libraries have been trying to get a deal for years. We need the coercive power of the state sitting behind us at the table saying, 'We need a special slice of the pie.'"

The Biden administration is poised to open up a new front in its effort to safeguard U.S. AI from China with preliminary plans to place guardrails around the most advanced AI models, the core software of artificial intelligence systems like ChatGPT, Reuters reported Wednesday. From the report: The Commerce Department is considering a new regulatory push to restrict the export of proprietary or closed source AI models, whose software and the data it is trained on are kept under wraps, three people familiar with the matter said. Any action would complement a series of measures put in place over the last two years to block the export of sophisticated AI chips to China in an effort to slow Beijing's development of the cutting edge technology for military purposes. Even so, it will be hard for regulators to keep pace with the industry's fast-moving developments.

Currently, nothing is stopping U.S. AI giants like Microsoft-backed OpenAI, Alphabet's Google DeepMind and rival Anthropic, which have developed some of the most powerful closed source AI models, from selling them to almost anyone in the world without government oversight. Government and private sector researchers worry U.S. adversaries could use the models, which mine vast amounts of text and images to summarize information and generate content, to wage aggressive cyber attacks or even create potent biological weapons. To develop an export control on AI models, the sources said the U.S. may turn to a threshold contained in an AI executive order issued last October that is based on the amount of computing power it takes to train a model. When that level is reached, a developer must report its AI model development plans and provide test results to the Commerce Department.

An anonymous reader quotes a report from MSN: The US has revoked licenses allowing Huawei to buy semiconductors from Qualcomm and Intel, according to people familiar with the matter, further tightening export restrictions against the Chinese telecom equipment maker. Withdrawal of the licenses affects US sales of chips for use in Huawei phones and laptops, according to the people, who discussed the move on condition of anonymity. House Foreign Affairs Committee Chairman Michael McCaul confirmed the administration's decision in an interview Tuesday. He said the move is key to preventing China from developing advanced AI. "It's blocking any chips sold to Huawei," said McCaul, a Texas Republican who was briefed about the license decisions for Intel and Qualcomm. "Those are two companies we've always worried about being a little too close to China."

While the decision may not affect a significant volume of chips, it underscores the US government's determination to curtail China's access to a broad swathe of semiconductor technology. Officials are also considering sanctions against six Chinese firms that they suspect could supply chips to Huawei, which has been on a US trade restrictions list since 2019. [...] Qualcomm recently said that its business with Huawei is already limited and will soon shrink to nothing. It has been allowed to supply the Chinese company with chips that provide older 4G network connections. It's prohibited from selling ones that allow more advanced 5G access.

Computer models have found that recent heat waves in the north Pacific may be due to a large reduction in aerosols emitted by factories in China. The findings have been published in the Proceedings of the National Academy of Sciences. Phys.Org reports: In this new effort, the research team noted that the onset of the heat waves appeared to follow successful efforts by the Chinese government to reduce aerosol emissions from their country's factories. Beginning around 2010, factories and power generating plants in China began dramatically reducing emissions of aerosols such as sulfate, resulting in much cleaner air. Noting that aerosols can act like mirrors floating in the air, reflecting heat from the sun back into space, and also pointing out that earlier research efforts had suggested that massive reductions of aerosols in one place could lead to warming in other places -- they wondered if reductions of aerosols in China might be playing a role in the heat waves that began happening in the north Pacific.

To find out if that might be the case, the team began collecting data and then input it into 12 different computer climate models. They ran them under two conditions -- one where emissions from East Asia remained as they were over the past several decades and one where they dropped in the way they had in reality. They found that the models with no declines did not cause much change elsewhere, whereas those with aerosol drops showed heat waves occurring in the northeast parts of the Pacific Ocean.

The models also showed why -- as less heat was reflected back into space over China, warming of coastal regions in Asia began, resulting in the development of high-pressure systems. That in turn made low-pressure systems in the middle Pacific more intense. And that resulted in the Aleutian Low growing bigger and moving south which weakened the westerly winds that typically cool the sea surface. The result was hotter conditions.

Renewable energy accounted for more than 30% of the world's electricity for the first time last year, according to climate thinktank Ember. The Guardian reports: Clean electricity has already helped to slow the growth in fossil fuels by almost two-thirds in the past 10 years, according to the report by climate thinktank Ember. It found that renewables have grown from 19% of electricity in 2000 to more than 30% of global electricity last year. Solar was the main supplier of electricity growth, according to Ember, adding more than twice as much new electricity generation as coal in 2023. It was the fastest-growing source of electricity for the 19th consecutive year, and also became the largest source of new electricity for the second year running, after surpassing wind power.

The first comprehensive review of global electricity data covers 80 countries, which represent 92% of the world's electricity demand, as well as historic data for 215 countries. The surge in clean electricity is expected to power a 2% decrease in global fossil fuel generation in the year ahead, according to Ember. [...] World leaders are aiming to grow renewables to 60% of global electricity by 2030 under an agreement struck at the UN's Cop28 climate change conference in December. This would require countries to triple their current renewable electricity capacity in the next six years, which would almost halve power sector emissions.

Lawyers for the defunct cryptocurrency exchange FTX said customers would receive all the money they lost when the firm collapsed in 2022 and receive interest on top of it. "But the recoveries come with a caveat," reports the New York Times. "The amount owed to customers was calculated based on the value of their holdings at the time of FTX's bankruptcy in November 2022. That means customers won't reap the benefits of a recent surge in the crypto market that sent the price of Bitcoin to a record high." From the report: The announcement was a landmark in the attempt to recover the $8 billion in customer assets that disappeared when FTX imploded virtually overnight, setting off a crisis in the crypto industry. Under a plan filed in federal bankruptcy court in Delaware, virtually all FTX's creditors, including hundreds of thousands of ordinary investors who used the exchange to buy and sell cryptocurrencies, would receive cash payments equivalent to 118 percent of the assets they had stored on FTX, the lawyers said. Those payments would flow from a pool of assets that FTX's lawyers have pulled together in the 17 months since the exchange collapsed, the lawyers said. [...] It will take months for the payouts to begin. The plan must be approved by the federal judge overseeing FTX's bankruptcy, John T. Dorsey.

An anonymous reader quotes a report from Wired: Amazon plans to start flying delivery drones in Arizona this year -- but don't count on them to bring you a refreshing drink on a hot day. The hexacopter can't operate when temperatures top 104 degrees Fahrenheit, or 40 degrees Celsius, the company says, and average daily highs exceed that for three months of the year in Tolleson, the city outside Phoenix where Amazon is preparing to offer aerial deliveries from inside a 7.5-mile radius. The drones can't help with midnight snacks either, because they'll be grounded after sunset. Potentially being inoperable for a quarter of the year might make launching drone deliveries in Tolleson and neighboring desert communities seem like an odd choice. It's far from the first challenge faced by Amazon's much-delayed drone project. The unit is years behind its goals of flying items to customers in under an hour on a regular basis, and a one-time target of 500 million deliveries by 2030 seems distant. Amazon Prime Air has completed just thousands of deliveries, falling behind rivals; Alphabet subsidiary Wing has notched hundreds of thousands of delivery flights and Walmart more than 20,000.

In the California wine country town of Lockeford, where Amazon initially launched drone deliveries, some residents told WIRED last year that they ordered only because Amazon lured them with gift cards. In Arizona, it could be discouraging not being able to rely on drones during those hours when one might not want to venture too far from the comfort of air conditioning. [...] That temperature and other environmental conditions could ground or hamper the drone industry has been known for years. A team from University of Calgary's geography department estimated that on average across the world, drones with limitations similar to Amazon's, including from weather and daylight, would be limited to flying about 2 hours a day. In the world's 100 most populous cities, the average daily flight time would be 6 hours. "Weather is an important and poorly resolved factor that may affect ambitions to expand drone operations," they wrote in a study published in 2021. Heat, in particular, forces motors to work harder to keep drones aloft, and their batteries are only so powerful.

Wayve, a UK-based AI firm focused on developing self-driving car technology, has secured a record $1.05 billion in funding, with Microsoft and Nvidia participating in the round led by SoftBank. According to the BBC, this investment is the largest for an AI company in Europe. The BBC reports: Wayve says the funding will allow it to help build the autonomous cars of the future. [...] Wayve is developing technology intended to power future self-driving vehicles by using what it calls "embodied AI." Unlike AI models carrying out cognitive or generative tasks such as answering questions or creating pictures, this new technology interacts with and learns from real-world surroundings and environments. "[The investment] sends a crucial signal to the market of the strength of the UK's AI ecosystem, and we look forward to watching more AI companies here thrive and scale," said Wayve head Alex Kendall.

An anonymous reader shares a report: The Federal Aviation Administration is investigating whether Boeing failed to complete required inspections on 787 Dreamliner planes and whether Boeing employees falsified aircraft records, the agency said this week. The investigation was launched after an employee reported the problem to Boeing management, and Boeing informed the FAA. "The FAA has opened an investigation into Boeing after the company voluntarily informed us in April that it may not have completed required inspections to confirm adequate bonding and grounding where the wings join the fuselage on certain 787 Dreamliner airplanes," the FAA said in a statement provided to Ars today. The FAA said it "is investigating whether Boeing completed the inspections and whether company employees may have falsified aircraft records. At the same time, Boeing is reinspecting all 787 airplanes still within the production system and must also create a plan to address the in-service fleet." The agency added that it "will take any necessary action -- as always -- to ensure the safety of the flying public."

Boeing VP Scott Stocker, who leads the 787 Dreamliner program, described "misconduct" in an April 29 email to employees in South Carolina. Boeing provided a copy of the email to Ars. "After receiving the report, we quickly reviewed the matter and learned that several people had been violating Company policies by not performing a required test, but recording the work as having been completed," Stocker wrote. "As you all know, we have zero tolerance for not following processes designed to ensure quality and safety. We promptly informed our regulator about what we learned and are taking swift and serious corrective action with multiple teammates."
