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."

Less than two weeks after President Biden signed a bill that will force TikTok's Chinese owner, ByteDance, to sell the popular social media app or face a ban in the United States, TikTok said it sued the federal government on Tuesday, arguing the law was unconstitutional. From a report: TikTok said that the law violated the First Amendment by effectively removing an app that millions of Americans use to share their views and communicate freely. It also argued that a divestiture was "simply not possible," especially within the law's 270-day timeline, pointing to difficulties such as Beijing's refusal to sell a key feature that powers TikTok in the United States.

"For the first time in history, Congress has enacted a law that subjects a single, named speech platform to a permanent, nationwide ban, and bars every American from participating in a unique online community with more than one billion people worldwide," the company said in the 67-page petition it provided, which initiates the lawsuit. "There is no question: The act will force a shutdown of TikTok by Jan. 19, 2025." TikTok is battling for its survival in the United States, with the fight set to play out primarily in courts over the next few months. While lawmakers who passed the bill have said the app is a national security threat because of its ties to China, the courts must now weigh those concerns against TikTok's argument that a sale or ban would violate the First Amendment free-speech rights of its users and hurt small businesses that owe their livelihood to the platform.

The identity of the leader of one of the most infamous ransomware groups in history has finally been revealed. From a report: On Tuesday, a coalition of law enforcement led by the U.K.'s National Crime Agency announced that Russian national, Dmitry Yuryevich Khoroshev, 31, is the person behind the nickname LockBitSupp, the administrator and developer of the LockBit ransomware. The U.S. Department of Justice also announced the indictment of Khoroshev, accusing him of computer crimes, fraud and extortion.

"Today we are going a step further, charging the individual who we allege developed and administered this malicious cyber scheme, which has targeted over 2,000 victims and stolen more than $100 million in ransomware payments," Attorney General Merrick B. Garland was quoted as saying in the announcement. According to the DOJ, Khoroshev is from Voronezh, a city in Russia around 300 miles south of Moscow. "Dmitry Khoroshev conceived, developed, and administered Lockbit, the most prolific ransomware variant and group in the world, enabling himself and his affiliates to wreak havoc and cause billions of dollars in damage to thousands of victims around the globe," said U.S. Attorney Philip R. Sellinger for the District of New Jersey, where Khoroshev was indicted.

Swedish energy company Stockholm Exergi and Microsoft have announced a 10-year deal that will provide the tech giant with more than 3.3 million tons of carbon removal certificates through bioenergy with carbon capture and storage. While the value of the deal was not disclosed, it stands as the largest of its kind globally. Carbon Herald reports: Scheduled to commence in 2028 and span a decade, the agreement underscores a pivotal moment in combatting climate change. Anders Egelrud, CEO of Stockholm Exergi, lauded the deal as a "huge step" for the company and its BECCS project, emphasizing its profound implications for climate action. "I believe the agreement will inspire corporations with ambitious climate objectives, and we target to announce more deals with other pioneering companies over the coming months," he said. Recognizing the imperative of permanent carbon removals in limiting global warming to 1.5C or below, the deal aligns with Microsoft's ambitious goal of becoming carbon negative by 2030.

"Leveraging existing biomass power plants is a crucial first step to building worldwide carbon removal capacity," Brian Marrs, Microsoft's Senior Director of Energy & Carbon Removal, said, highlighting the importance of sustainable biomass sourcing for BECCS projects, as is the case with Stockholm Exergi. The partners will adhere to stringent quality standards, ensuring transparent reporting and adherence to sustainability criteria. The BECCS facility, once operational, will remove up to 800,000 tons of carbon dioxide (CO2) annually, contributing significantly to atmospheric carbon reduction. With environmental permits secured and construction set to commence in 2025, Stockholm Exergi plans to reach the final investment decision by the end of the year.

Shell sold millions of carbon credits tied to CO2 removal that never took place [non-paywalled link] to Canada's largest oil sands companies, raising new doubts about a technology seen as crucial to mitigating greenhouse gas emissions. FT: As part of a subsidy scheme to boost the industry, the Alberta provincial government allowed Shell to register and sell carbon credits equivalent to twice the volume of emissions avoided by its Quest carbon capture facility between 2015 and 2021, the province's registry shows. The subsidy was reduced and then ended in 2022.

As a result of the scheme, Shell was able to register 5.7mn credits that had no equivalent CO2 reductions, selling these to top oil sands producers and some of its own subsidiaries. Credits are typically equivalent to one tonne of CO2. Some of the largest buyers of the credits were Chevron, Canadian Natural Resources, ConocoPhillips, Imperial Oil and Suncor Energy. Keith Stewart, a senior energy strategist with Greenpeace Canada, criticised these "phantom credits." Stewart added: "Selling emissions credits for reductions that never happened ... literally makes climate change worse."

Shell said carbon capture played "an important role in helping to decarbonise industry and sectors where emissions cannot be avoided" and that realising its potential "requires creating market incentives now." Alberta's environment ministry said the crediting support scheme had not resulted in "additional emissions" by industrial polluters.

A council has provoked the wrath of residents and linguists alike after announcing it would ban apostrophes on street signs to avoid problems with computer systems. From a report: North Yorkshire council is ditching the punctuation point after careful consideration, saying it can affect geographical databases. The council said all new street signs would be produced without one, regardless of whether they were used in the past. Some residents expressed reservations about removing the apostrophes, and said it risked "everything going downhill." They urged the authority to retain them.

Sam, a postal worker in Harrogate, a spa town in North Yorkshire, told the BBC that signs missing an apostrophe -- such as the nearby St Mary's Walk sign that had been erected in the town without it -- infuriated her. "I walk past the sign every day and it riles my blood to see inappropriate grammar or punctuation," she said. Though the updated St Mary's sign had no apostrophe, someone had graffitied an apostrophe back on to the sign with a marker pen, which the former teacher said was "brilliant." She suggested the council was providing a bad example to children who spend a long time learning the basics of grammar only to see it not being used correctly on street signs.

Dr Ellie Rye, a lecturer in English language and linguistics at the University of York, said apostrophes were a relatively new invention in our writing and, often, context allows people to understand their meaning. "If I say I live on St Mary's Walk, we're expecting a street name or an address of some kind." She said the change would matter to people who spend a long time teaching how we write English but that it was "less important in [verbal] communication."

Poor countries must demonstrate clearer accounting and transparency to back up their calls for trillions of dollars of climate finance, the president of global climate negotiations has said. From a report: Mukhtar Babayev, the ecology minister of Azerbaijan, who will lead the Cop29 UN climate summit in November, urged governments in developing countries to draw up reports showing their progress on cutting greenhouse gas emissions, and their spending on the climate crisis. "It's very important to build this correct, good and honest trust between the parties," he said in an interview in Baku, the capital of Azerbaijan. "It's a very, very important step, the creation of a transparency mechanism between the countries."

At Cop29 in Baku, countries will be expected to come up with a new global goal on supplying climate finance to poorer countries, to help them cut their greenhouse gas emissions and adapt to the impacts of extreme weather. Some governments from the global south are calling for the sums to reach more than $1tn a year. These pledges are expected to be subject to bitter wrangling at Cop29, as rich countries are unlikely to agree to provide anything like such sums from their taxpayers but the role of other sources of finance -- such as the private sector -- is still in question.

An international coalition of police agencies have resurrected the dark web site of the notorious LockBit ransomware gang, which they had seized earlier this year, teasing new revelations about the group. From a report: On Sunday, what was once LockBit's official darknet site reappeared online with new posts that suggest the authorities are planning to release new information about the hackers in the next 24 hours, as of this writing. The posts have titles such as "Who is LockBitSupp?," "What have we learnt," "More LB hackers exposed," and "What have we been doing?"

In February, a law enforcement coalition that included the U.K.'s National Crime Agency, the U.S. Federal Bureau of Investigation, as well as forces from Germany, Finland, France, Japan and others announced that they had infiltrated LockBit's official site. The coalition seized the site and replaced information on it with their own press release and other information in a clear attempt to troll and warn the hackers that the authorities were on to them.

More than 90% of stablecoin transaction volumes aren't coming from genuine users, according to a new metric co-developed by Visa, suggesting such crypto tokens may be far away from becoming a commonly used means of payment. Bloomberg: The dashboard from Visa and Allium Labs is designed to strip out transactions initiated by bots and large-scale traders to isolate those made by real people. Out of about $2.2 trillion in total transactions in April, just $149 billion originated from "organic payments activity," according to Visa.

Visa's finding challenges stablecoin proponents' argument that the tokens, pegged to an asset like the dollar, are poised to revolutionize the $150 trillion payments industry. PayPal and Stripe are among the fintech giants making inroads into stablecoins, with Stripe co-founder John Collison in April citing "technical improvements" for being bullish on the tokens. [...] Visa itself, which handled more than $12 trillion worth of transactions last year, is among companies that could stand to lose out should stablecoins become a generally accepted means of payment.

Wednesday Rest of World noticed an overlooked tech story in Argentina: Olga de León looked confused as she walked out of a nightclub on the edge of Buenos Aires on a recent Tuesday afternoon. She had just had her iris scanned. "No one told me what they'll do with my eye," de León, 57, told Rest of World. "But I did this out of need." De León, who lives off the $95 pension she receives from the state, had been desperate for money. Persuaded by her nephew, she agreed to have one of her irises scanned by Worldcoin, Sam Altman's blockchain project. In exchange, she received nearly $50 worth of WLD, the company's cryptocurrency.

De León is one of about half a million Argentines who have handed their biometric data over to Worldcoin. Beaten down by the country's 288% inflation rate and growing unemployment, they have flocked to Worldcoin Orb verification hubs, eager to get the sign-up crypto bonus offered by the company. A network of intermediaries — who earn a commission from every iris scan — has lured many into signing up for the practice in Argentina, where data privacy laws remain weak. But as the popularity of Worldcoin skyrockets in the country, experts have sounded the alarm about the dangers of giving away biometric data. Two provinces are now pushing for legal investigations. "Seeing that [iris scans have] been banned in European countries, shouldn't we be trying to stop it, too?" Javier Smaldone, a software consultant and digital security expert, told Rest of World.
Last month Worldcoin's web site announced that more than 10 million people in 160 countries had created a World ID and compatible wallet (performing 75 million transactions) — and that 5,195,475 people had also verified their World ID using Worldcoin's iris-scanning Orb.

But the article notes a big drop in the number of countries even allowing Worldcoin's iris-scanning — from 25 to just eight. While in less than a year Worldcoin opened nearly 60 centers across Argentina...

A "string of legal victories" by America's market-regulating Securities and Exchange Commission "has jolted some of crypto's biggest players," reports Politico — even as they're seeking more credibility with U.S. lawmakers: Judges have recently rebuked claims that the SEC lacks authority to police the market. Coinbase, the largest U.S. exchange, lost a bid to throw out charges that it is violating investor-protection rules. And a New York jury found one-time billionaire entrepreneur Do Kwon and his firm liable for fraud. Now, the crackdown is about to expand, with the SEC preparing for a new round of lawsuits. "The SEC just keeps winning," said John Reed Stark, a former agency attorney and prominent crypto critic. "The law is catching up...."

[I]t's the SEC crackdown that is raising foundational questions about crypto's future. [SEC Chairman Gary] Gensler has been among the industry's most implacable foes, saying most crypto tokens are unregistered securities that are being sold illegally and blasting the industry as "rife with fraud, scams, bankruptcies and money laundering." His opposition has been so unwavering that many in the industry are holding out hope that he leaves the agency after the November elections...

[T]he SEC's enforcement sweep appears to be on the brink of spreading across the crypto world. Consensys is facing potential charges from the agency, according to the company's lawsuit. And the SEC recently warned Uniswap Labs, a decentralized finance company that created one of the world's largest DeFi exchanges, that staff was preparing to sue.

Uniswap executives have vowed to fight the agency in court.

The Associated Press reports that an F-16 performing aerial combat tests at 550 miles per hour was "controlled by artificial intelligence, not a human pilot."

And riding in the front seat was the U.S. Secretary of the Air Force... AI marks one of the biggest advances in military aviation since the introduction of stealth in the early 1990s, and the Air Force has aggressively leaned in. Even though the technology is not fully developed, the service is planning for an AI-enabled fleet of more than 1,000 unmanned warplanes, the first of them operating by 2028.

It was fitting that the dogfight took place at [California's] Edwards Air Force Base, a vast desert facility where Chuck Yeager broke the speed of sound and the military has incubated its most secret aerospace advances. Inside classified simulators and buildings with layers of shielding against surveillance, a new test-pilot generation is training AI agents to fly in war. [U.S. Secretary of the Air Force] Frank Kendall traveled here to see AI fly in real time and make a public statement of confidence in its future role in air combat.

"It's a security risk not to have it. At this point, we have to have it," Kendall said in an interview with The Associated Press after he landed... At the end of the hourlong flight, Kendall climbed out of the cockpit grinning. He said he'd seen enough during his flight that he'd trust this still-learning AI with the ability to decide whether or not to launch weapons in war... [T]he software first learns on millions of data points in a simulator, then tests its conclusions during actual flights. That real-world performance data is then put back into the simulator where the AI then processes it to learn more.
"Kendall said there will always be human oversight in the system when weapons are used," the article notes.

But he also said looked for to the cost-savings of smaller and cheaper AI-controlled unmanned jets.

Last month Reuters reported that Venezuela's state-run oil company "plans to increase digital currency usage in its crude and fuel exports as the U.S. reimposes oil sanctions on the country, three people familiar with the plan said." [The oil company] since last year had been slowly moving oil sales to USDT, a digital currency also known as Tether whose value is pegged to the U.S. dollar and designed to maintain a stable value. The return of oil sanctions is speeding up the shift, a move to reduce the risk of sale proceeds getting frozen in foreign bank accounts due to the measures, the people said...

Tether said in an email it respects the U.S. Treasury's list of sanctioned entities and "is committed to working to ensure sanction addresses are frozen promptly."
This week Reuters reported that now experts are saying the situation "will require greater scrutiny by regulators and law enforcement." They spoke to Kristofer Doucett, national security leader at U.S. blockchain analysis firm Chainalysis, who said "Structures must be set up to combat this type of money laundering." Reuters writes: Technology for digital transactions is changing fast and transactions are rapidly growing in developing regions including Latin America and Africa benefiting people without access to the banking system. But some corrupt governments are moving faster, making it difficult to prevent fraud, the experts said. Doucette and Sigal Mandelker, a lawyer who previously worked at the U.S. Treasury Department, said during a conference organized by the Wilson Center in Washington that the U.S. administration is making efforts to increase regulation and encourage other countries to improve supervision.
Slashdot reader RossCWilliams asks a loaded question. Whether this is "the beginning of the end of unregulated cryptocurrencies... the recognition of cryptocurrency as a national security threat that threatens international financial controls."

Come 2029, all cars sold in the U.S. "must be able to stop and avoid contact with a vehicle in front of them at speeds up to 62 mph," reports Car and Driver.

"Additionally, the system must be able to detect pedestrians in both daylight and darkness. As a final parameter, the federal standard will require the system to apply the brakes automatically up to 90 mph when a collision is imminent, and up to 45 mph when a pedestrian is detected." Notably, the federal standardization of automated emergency braking systems includes pedestrian-identifying emergency braking, too. Once implemented, the NHTSA projects that this standard will save at least 360 lives a year and prevent at least 24,000 injuries annually. Specifically, the federal agency claims that rear-end collisions and pedestrian injuries will both go down significantly...

"Automatic emergency braking is proven to save lives and reduce serious injuries from frontal crashes, and this technology is now mature enough to require it in all new cars and light trucks. In fact, this technology is now so advanced that we're requiring these systems to be even more effective at higher speeds and to detect pedestrians," said NHTSA deputy administrator Sophie Shulman.

The blog It's FOSS is "pissed at the casual arrogance of Ubuntu and its parent company Canonical..... The sheer audacity of not caring for its users reeks of Microsoft-esque arrogance." If you download a .deb package of a software, you cannot install it using the official graphical software center on Ubuntu anymore. When you double-click on the downloaded deb package, you'll see this error, "there is no app installed for Debian package files".

If you right-click and choose to open it with Software Center, you are in for another annoyance. The software center will go into eternal loading. It may look as if it is doing something, but it will go on forever. I could even livestream the loading app store on YouTube, and it would continue for the 12 years of its long-term support period.
Canonical software engineer Dennis Loose actually created an issue ticket for the problem himself — back in September of 2023. And two weeks ago he returned to the discussion to announce that fix "will be a priority for the next cycle". (Though "unfortunately we didn't have the capacity to work on this for 24.04...)

But Its Foss accused Canonical of "cleverly booting out deb in favor of Snap, one baby step at a time" (noting the problem started with Ubuntu 23.10): There is also the issue of replacing deb packages with Snap, even with the apt command line tool. You use 'sudo apt install chromium', you get a Snap package of Chromium instead of Debian
The venerable Linux magazine argues that Canonical "has secretly forced Snap installation on users." [I]t looks as if the Software app defaults to Snap packages for everything now. I combed through various apps and found this to be the case.... As far as the auto-installation of downloaded .deb files, you'll have to install something like gdebi to bring back this feature.
