How Internet Pioneers Celebrated 50 Years of the Internet (i50ieee.com) 7

Founded in 1963, the Institute of Electrical and Electronics Engineers held a special event Sunday that they said would be "inspiring engineering for the next 50 years."

The event featured talks on the origins of the internet from 80-year-old "father of the internet" Vint Cerf, along with John Shoch (who helped develop the Ethernet and internetwork protocols at Xerox PARC), Judith Estrin (who worked with Cerf on the TCP project), and Robert Kahn (who with Cerf first proposed the IP and TCP protocols). Ethernet co-inventor Bob Metcalfe also spoke at the end of the event.

Long-time Slashdot reader repett0 was an onsite volunteer, and shares that "it was incredible to meet and greet such a wonderful mix of people making technology happen... [T]he event celebrated many key technologies and innovators from the past 50 years and considerations of what is to come in the next 50 years." Video streams are available and more are coming online (including interviews with key innovators, society leadership, and more). If you could not make this event, follow-on activities continue, including the People-Centered Internet Imagine Workshop where a mix of society is working together to consider how to improve humanity's intersection with ever-expanding abilities thanks to technology.
They add that the event was made possible "through the collaboration of many professional computing societies" including the IEEE, People-Centered Internet, Google, Internet Society, IEEE Computer Society, GIANT Protocol, IEEE Foundation — and volunteers from the SF Bay Area ACM and Internet Society.

American Radio Relay League Confirms Cyberattack Disrupted Operations (bleepingcomputer.com) 32

Roughly 160,000 U.S.-based amateur radio enthusiasts belong to the American Radio Relay League, a nonprofit with 100 full-time and part-time staff members.

Nine days ago it announced "that it suffered a cyberattack that disrupted its network and systems," reports BleepingComputer, "including various online services hosted by the organization." "We are in the process of responding to a serious incident involving access to our network and headquarters-based systems. Several services, such as Logbook of The World and the ARRL Learning Center, are affected," explained ARRL in a press release... [T]he ARRL took steps to allay members' concerns about the security of their data, confirming that they do not store credit card information or collect social security numbers.

However, the organization confirmed that its member database contains some private information, including names, addresses, and call signs. While they do not specifically state email addresses are stored in the database, one is required to become a member of the organization.

"The ARRL has not specifically said that its member database has been accessed by hackers," Security Week points out, "but its statement suggests it's possible."

The site adds that it has also "reached out to ARRL to find out if this was a ransomware attack and whether the attackers made any ransom demand."

Robotaxis Face 'Heightened Scrutiny' While the Industry Plans Expansion (msn.com) 19

Besides investigations into Cruise and Waymo, America's National Highway Traffic Safety Administration (NHTSA) also announced it's examining two rear-end collisions between motorbikes and Amazon's steering wheel-free Zoox vehicles being tested in San Francisco, Seattle, and Las Vegas.

This means all three major self-driving vehicle companies "are facing federal investigations over potential flaws linked to dozens of crashes," notes the Washington Post, calling it "a sign of heightened scrutiny as the fledging industry lays plans to expand nationwide." The industry is poised for growth: About 40 companies have permits to test autonomous vehicles in California alone. The companies have drawn billions of dollars in investment, and supporters say they could revolutionize how Americans travel... Dozens of companies are testing self-driving vehicles in at least 10 states, with some offering services to paying passengers, according to the Autonomous Vehicle Industry Association. The deployments are concentrated in a handful of Western states, especially those with good weather and welcoming governors.

According to a Washington Post analysis of California data, the companies in test mode in San Francisco collectively report millions of miles on public roads every year, along with hundreds of mostly minor collisions. An industry association says autonomous vehicles have logged a total of 70 million miles, a figure that it compares with 293 trips to the moon and back. But it's a tiny fraction of the almost 9 billion miles that Americans drive every day. The relatively small number of miles the vehicles have driven makes it difficult to draw broad conclusions about their safety.

Key quotes from the article:
  • "Together, the three investigations opened in the past year examine more than two dozen collisions potentially linked to defective technology. The bulk of the incidents were minor and did not result in any injuries..."
  • "But robotic cars are still very much in their infancy, and while the bulk of the collisions flagged by NHTSA are relatively minor, they call into question the companies' boasts of being far safer than human drivers..."
  • "The era of unrealistic expectations and hype is over," said Matthew Wansley, a professor at the Cardozo School of Law in New York who specializes in emerging automotive technologies. "These companies are under a microscope, and they should be. Private companies are doing an experiment on public roads."
  • "Innocent people are on the roadways, and they're not being protected as they need to be," said Cathy Chase, the president of Advocates for Highway and Auto Safety.

Satya Nadella Says Microsoft's AI-Focused Copilot+ Laptops Will Outperform Apple's MacBooks (msn.com) 86

"Apple's done a fantastic job of really innovating on the Mac," Microsoft CEO Satya Nadella told the Wall Street Journal in a video interview this week.

. Then he said "We are gonna outperform them" with the upcoming Copilot+ laptops from Acer, ASUS, Dell, HP, Lenovo and Samsung that have been completely reengineered for AI — and begin shipping in less than four weeks. Satya Nadella: Qualcomm's got a new [ARM Snapdragon X] processor, which we've optimized Windows for. The battery lab, I've been using it now — I mean, it's 22 hours of continuous video playback... [Apple also uses ARM chips in its MacBooks]. We finally feel we have a very competitive product between Surface Pro and the Surface laptops. We have essentially the best specs when it comes to ARM-based silicon and performance or the NPU performance.

WSJ: Microsoft says the Surfaces are 58% faster than the MacBook Air with M3, and has 20% longer battery life.

The video includes a demonstration of local live translation powered by "small language models" stored on the device. ("It can translate live video calls or in-person conversations from 44 different languages into English. And it's fast.")

And in an accompanying article, the Journal's reporter also tested out the AI-powered image generator coming to Microsoft Paint.

As a longtime MS Paint stick-figure and box-house artist, I was delighted by this new tool. I typed in a prompt: "A Windows XP wallpaper with a mountain and sky." Then, as I started drawing, an AI image appeared in a new canvas alongside mine. When I changed a color in my sketch, it changed a color in the generated image. Microsoft says it still sends the prompt to the cloud to ensure content safety.
Privacy was also touched on. Discussing the AI-powered "Recall" search functionality, the Journal's reporter notes that users can stop it from taking screenshots of certain web sites or apps, or turn it off entirely... But they point out "There could be this reaction from some people that this is pretty creepy. Microsoft is taking screenshots of everything I do."

Nadella reminds them that "it's all being done locally, right...? That's the promise... That's one of the reasons why Recall works as a magical thing: because I can trust it, that it is on my computer."

Copilot will be powered by OpenAI's new GPT-4o, the Journal notes — before showing Satya Nadella saying "It's kind of like a new browser effectively." Satya Nadella: So, it's right there. It sees the screen, it sees the world, it hears you. And so, it's kind of like that personal agent that's always there that you want to talk to. You can interrupt it. It can interrupt you.
Nadella says though the laptop is optimized for Copilot, that's just the beginning, and "I fully expect Copilot to be everywhere" — along with its innovatively individualized "personal agent" interface. "It's gonna be ambient.... It'll go on the phone, right? I'll use it on WhatsApp. I'll use it on any other messaging platform. It'll be on speakers everywhere." Nadella says combining GPT-40 with Copilot's interface is "the type of magic that we wanna bring — first to Windows and everywhere else... The future I see is a computer that understands me versus a computer that I have to understand.

The interview ends when the reporter holds up the result — their own homegrown rendition of Windows XP's default background image "Bliss."

Meta, Activision Sued By Parents of Children Killed in Last Year's School Shooting (msn.com) 153

Exactly one year after the fatal shooting of 19 elementary school students in Texas, their parents filed a lawsuit against the publisher of the videogame Call of Duty, against Meta, and against the manufacturer of the AR-15-style weapon used in the attack, Daniel Defense.

The Washington Post says the lawsuits "may be the first of their kind to connect aggressive firearms marketing tactics on social media and gaming platforms to the actions of a mass shooter." The complaints contend the three companies are responsible for "grooming" a generation of "socially vulnerable" young men radicalized to live out violent video game fantasies in the real world with easily accessible weapons of war...

Several state legislatures, including California and Hawaii, passed consumer safety laws specific to the sale and marketing of firearms that would open the industry to more civil liability. Texas is not one of them. But it's just one vein in the three-pronged legal push by Uvalde families. The lawsuit against Activision and Meta, which is being filed in California, accuses the tech companies of knowingly promoting dangerous weapons to millions of vulnerable young people, particularly young men who are "insecure about their masculinity, often bullied, eager to show strength and assert dominance."

"To put a finer point on it: Defendants are chewing up alienated teenage boys and spitting out mass shooters," the lawsuit states...

The lawsuit alleges that Meta, which owns Instagram, easily allows gun manufacturers like Daniel Defense to circumvent its ban on paid firearm advertisements to reach scores of young people. Under Meta's rules, gunmakers are not allowed to buy advertisements promoting the sale of or use of weapons, ammunition or explosives. But gunmakers are free to post promotional material about weapons from their own account pages on Facebook and Instagram — a freedom the lawsuit alleges Daniel Defense often exploited.

According to the complaint, the Robb school shooter downloaded a version of "Call of Duty: Modern Warfare," in November 2021 that featured on the opening title page the DDM4V7 model rifle [shooter Salvador] Ramos would later purchase. Drawing from the shooter's social media accounts, Koskoff argued he was being bombarded with explicit marketing and combat imagery from the company on Instagram... The complaint cites Meta's practice, first reported by The Washington Post in 2022, of giving gun sellers wide latitude to knowingly break its rules against selling firearms on its websites. The company has allowed buyers and sellers to violate the rule 10 times before they are kicked off, The Post reported.

The article adds that the lawsuit against Meta "echoes some of the complaints by dozens of state attorneys general and school districts that have accused the tech giant of using manipulative practices to hook... while exposing them to harmful content." It also includes a few excerpts from the text of the lawsuit.
  • It argues that both Meta and Activision "knowingly exposed the Shooter to the weapon, conditioned him to see it as the solution to his problems, and trained him to use it."
  • The lawsuit also compares their practices to another ad campaign accused of marketing harmful products to children: cigarettes. "Over the last 15 years, two of America's largest technology companies — Defendants Activision and Meta — have partnered with the firearms industry in a scheme that makes the Joe Camel campaign look laughably harmless, even quaint."

Meta and Daniel Defense didn't respond to the reporters' requests for comment. But they did quote a statement from Activision expressing sympathy for the communities and families impacted by the "horrendous and heartbreaking" shooting.

Activision also added that "Millions of people around the world enjoy video games without turning to horrific acts."

Eagles Changed Migration Route To Avoid Ukraine War 28

Scientists report that Greater Spotted Eagles altered their migration routes across Ukraine to avoid conflict and habitat destruction caused by the war. The BBC reports: The scientists studied GPS data from tagged birds in the months after the February 2022 invasion, a time of heavy fighting in northern Ukraine as Russia tried to take Kyiv by sending troops south from Belarus. The researchers from the Estonian University of Life Sciences and the British Trust for Ornithology reported their findings in the journal Current Biology. "The war in Ukraine has had a devastating impact on people and the environment. Our findings provide a rare window into how conflicts affect wildlife," said lead author Charlie Russell, a postgraduate researcher at the University of East Anglia.

Classified as a vulnerable species, the Greater Spotted Eagle is a large, brownish-colored bird of prey. Researchers started following them using GPS tracking devices in 2017 but didn't expect to be monitoring them through an active conflict zone five years later. The findings reveal they made large deviations from their previously tracked routes. They also spent less time stopping at their usual refueling sites in Ukraine or avoided them entirely. As a result, they traveled farther, about an extra 52 miles (85km) on average.

For migrating birds, stopover sites are essential places to get food, water, and shelter. These changes delayed the birds' arrival at the breeding grounds and likely made them use more energy, to damaging effect. "No doubt about it. I think the take-home story is that the conflict in Ukraine is fundamentally disrupting the migratory ecology of this species," said Dr Jim Reynolds, Assistant Professor in Ornithology and Animal Conservation at the University of Birmingham, who was independent from the study. "For a vulnerable species like this, anything that disrupts breeding performance is a major problem. As a conservation biologist, you worry about that in a massive way." Despite all the tagged birds surviving, researchers believe their experience may have affected their ability to breed.

Feds Add Nine More Incidents To Waymo Robotaxi Investigation (techcrunch.com) 36

Nine more accidents have been discovered by federal safety regulators during their safety investigation of Waymo's self-driving vehicles in Phoenix and San Francisco. TechCrunch reports: The National Highway Traffic Safety Administration Office of Defects Investigation (ODI) opened an investigation earlier this month into Waymo's autonomous vehicle software after receiving 22 reports of robotaxis making unexpected moves that led to crashes and potentially violated traffic safety laws. The investigation, which has been designated a "preliminary evaluation," is examining the software and its ability to avoid collisions with stationary objects and how well it detects and responds to "traffic safety control devices" like cones. The agency said Friday it has added (PDF) another nine incidents since the investigation was opened.

Waymo reported some of these incidents. The others were discovered by regulators via public postings on social media and forums like Reddit, YouTube and X. The additional nine incidents include reports of Waymo robotaxis colliding with gates, utility poles, and parked vehicles, driving in the wrong lane with nearby oncoming traffic and into construction zones. The ODI said it's concerned the robotaxis "exhibiting such unexpected driving behaviors may increase the risk of crash, property damage, and injury." The agency said that while it's not aware of any injuries from these incidents, several involved collisions with visible objects that "a competent driver would be expected to avoid." The agency also expressed concern that some of these occurred near pedestrians. NHTSA has given Waymo until June 11 to respond to a series of questions regarding the investigation.

Google Threatens To Pause Google News Initiative Funding In US (axios.com) 20

Google has warned nonprofit newsrooms that a new California bill taxing Big Tech for digital ad transactions would jeopardize future investments in the U.S. news industry. "This is the second time this year Google has threatened to pull investment in news in response to a regulatory threat in California -- but this time, hundreds of publishers outside of California would also feel the impact," reports Axios. From the report: Google's new outreach to smaller news outlets is happening in response to a different bill, introduced this year by State Sen. Steve Glazer, that would tax Big Tech companies like Google and Meta for "data extraction transactions," or digital ad transactions. Tax revenue would fund tax credits meant to support the hiring of more journalists in California by eligible nonprofit local news organizations. With the link tax bill, Google only threatened to pull news investments in California. But the company is telling partners that the ad tax proposal will threaten consideration of new grants nationwide by the Google News Initiative, which funds hundreds of smaller news outlets, sources told Axios. Previous commitments, however, should be secure. A spokesperson for the Institute for Nonprofit News said the organization believes that grants previously committed through GNI as described here "are secure, so INN members should continue to benefit through this particular Fundamentals Labs program."

Google's concern, sources familiar with the company's thinking told Axios, is that the new California ad tax bill could set a troubling wider precedent for other states. California's Senate tax committee approved the "ad tax" bill May 8. Days after that, Google started making calls to nonprofits about potentially pausing future Google News Initiative funding, sources told Axios. Opponents argue (PDF) the ad tax burden would get passed down to consumers and businesses. They also say the measure would face legal challenges, similar to a digital ad tax introduced in Maryland last year.

Google Search's 'udm=14' Trick Lets You Kill AI Search For Good (arstechnica.com) 40

An anonymous reader quotes a report from Ars Technica: If you're tired of Google's AI Overview extracting all value from the web while also telling people to eat glue or run with scissors, you can turn it off -- sort of. Google has been telling people its AI box at the top of search results is the future, and you can't turn it off, but that ignores how Google search works: A lot of options are powered by URL parameters. That means you can turn off AI search with this one simple trick! (Sorry.) Our method for killing AI search is defaulting to the new "web" search filter, which Google recently launched as a way to search the web without Google's alpha-quality AI junk. It's actually pretty nice, showing only the traditional 10 blue links, giving you a clean (well, other than the ads), uncluttered results page that looks like it's from 2011. Sadly, Google's UI doesn't have a way to make "web" search the default, and switching to it means digging through the "more" options drop-down after you do a search, so it's a few clicks deep.

Check out the URL after you do a search, and you'll see a mile-long URL full of esoteric tracking information and mode information. We'll put each search result URL parameter on a new line so the URL is somewhat readable [...]. Most of these only mean something to Google's internal tracking system, but that "&udm=14" line is the one that will put you in a web search. Tack it on to the end of a normal search, and you'll be booted into the clean 10 blue links interface. While Google might not let you set this as a default, if you have a way to automatically edit the Google search URL, you can create your own defaults. One way to edit the search URL is a proxy site like udm14.com, which is probably the biggest site out there popularizing this technique. A proxy site could, if it wanted to, read all your search result queries, though (your query is also in the URL), so whether you trust this site is up to you.

Another US State Repeals Law That Protected ISPs From Municipal Competition (arstechnica.com) 34

Minnesota this week eliminated two laws that made it harder for cities and towns to build their own broadband networks. From a report: The state-imposed restrictions were repealed in an omnibus commerce policy bill signed on Tuesday by Gov. Tim Walz, a Democrat. Minnesota was previously one of about 20 states that imposed significant restrictions on municipal broadband. The number can differ depending on who's counting because of disagreements over what counts as a significant restriction. But the list has gotten smaller in recent years because states including Arkansas, Colorado, and Washington repealed laws that hindered municipal broadband. The Minnesota bill enacted this week struck down a requirement that municipal telecommunications networks be approved in an election with 65 percent of the vote. The law is over a century old, the Institute for Local Self-Reliance's Community Broadband Network Initiative wrote yesterday.

Apple Explains Rare iOS 17.5 Bug That Resurfaced Deleted Photos (9to5mac.com) 59

Apple has shed more light on the bizarre iOS 17.5 bug that caused long-deleted photos to mysteriously reappear on users' devices. In a statement to 9to5Mac, the iPhone maker clarified that the issue stemmed from a corrupted database on the device itself, not iCloud Photos. This means the photos were never fully erased from the device, but they also weren't synced to iCloud. Interestingly, these files could have hitched a ride to new devices through backups or direct transfers.

SpaceX Launches First Satellites For New US Spy Constellation (reuters.com) 36

fjo3 quotes a report from Reuters: SpaceX on Wednesday launched an inaugural batch of operational spy satellites it built as part of a new U.S. intelligence network designed to significantly upgrade the country's space-based surveillance powers, the first deployment of several more planned this year. The spy network was revealed in a pair of Reuters reports earlier this year showing SpaceX is building hundreds of satellites for the U.S. National Reconnaissance Office, an intelligence agency, for a vast system in orbit capable of rapidly spotting ground targets almost anywhere in the world.

SpaceX's Falcon 9 rocket lifted off from the Vandenberg Space Force Base in Southern California at 4 a.m. EDT on Wednesday, carrying into space what the NRO said was the "first launch of the NRO's proliferated systems featuring responsive collection and rapid data delivery." "Approximately half a dozen launches supporting NRO's proliferated architecture are planned for 2024, with additional launches expected through 2028," the agency said, without naming the number of satellites deployed.

Mark Zuckerberg Assembles Team of Tech Execs For AI Advisory Council (qz.com) 17

An anonymous reader quotes a report from Quartz: Mark Zuckerberg has assembled some of his fellow tech chiefs into an advisory council to guide Meta on its artificial intelligence and product developments. The Meta Advisory Group will periodically meet with Meta's management team, Bloomberg reported. Its members include: Stripe CEO and co-founder Patrick Collison, former GitHub CEO Nat Friedman, Shopify CEO Tobi Lutke, and former Microsoft executive and investor Charlie Songhurst.

"I've come to deeply respect this group of people and their achievements in their respective areas, and I'm grateful that they're willing to share their perspectives with Meta at such an important time as we take on new opportunities with AI and the metaverse," Zuckerberg wrote in an internal note to Meta employees, according to Bloomberg. The advisory council differs from Meta's 11-person board of directors because its members are not elected by shareholders, nor do they have fiduciary duty to Meta, a Meta spokesperson told Bloomberg. The spokesperson said that the men will not be paid for their roles on the advisory council.
TechCrunch notes that the council features "only white men on it." This "differs from Meta's actual board of directors and its Oversight Board, which is more diverse in gender and racial representation," reports TechCrunch.

"It's telling that the AI advisory council is composed entirely of businesspeople and entrepreneurs, not ethicists or anyone with an academic or deep research background. ... it's been proven time and time again that AI isn't like other products. It's a risky business, and the consequences of getting it wrong can be far-reaching, particularly for marginalized groups."

Leaked Contract Shows Samsung Forces Repair Shop To Snitch On Customers (404media.co) 34

Speaking of Samsung, samleecole shares a report about the contract the South Korean firm requires repair shops to sign: In exchange for selling them repair parts, Samsung requires independent repair shops to give Samsung the name, contact information, phone identifier, and customer complaint details of everyone who gets their phone repaired at these shops, according to a contract obtained by 404 Media. Stunningly, it also requires these nominally independent shops to "immediately disassemble" any phones that customers have brought them that have been previously repaired with aftermarket or third-party parts and to "immediately notify" Samsung that the customer has used third-party parts.

"Company shall immediately disassemble all products that are created or assembled out of, comprised of, or that contain any Service Parts not purchased from Samsung," a section of the agreement reads. "And shall immediately notify Samsung in writing of the details and circumstances of any unauthorized use or misappropriation of any Service Part for any purpose other than pursuant to this Agreement. Samsung may terminate this Agreement if these terms are violated."

YouTube Rolling Out Its Widely Hated New Web Redesign (9to5google.com) 61

Ben Schoon reports via 9to5Google: After first appearing earlier this year, YouTube once again appears to be rolling out a new redesign for its website that everyone hates. In mid-April, Google started testing a redesign to YouTube's website, which moved the title of the video, its description, and the comments to the side of the screen. In their place, video recommendations were moved directly underneath the video being watched with much larger thumbnails and titles. The change was widely hated by almost everyone who got it, but it didn't show up for all users. In the weeks to follow, YouTube reverted the redesign. Now, the YouTube redesign is back.

As spotted by many users, YouTube has started rolling out this redesign yet again. The new look has been appearing over the past few days, though it doesn't seem like it's a wide rollout. Rather, it appears to still be a test more than anything else. What does this second attempt mean? It's still unclear if YouTube intends to make this new look the default experience, but a second round of testing certainly implies more data is being gathered.

Google: Stop Trying To Trick Employees With Fake Phishing Emails (pcmag.com) 100

An anonymous reader shares a report: Did your company recently send you a phishing email? Employers will sometimes simulate phishing messages to train workers on how to spot the hacking threat. But one Google security manager argues the IT industry needs to drop the practice, calling it counterproductive. "PSA for Cybersecurity folk: Our co-workers are tired of being 'tricked' by phishing exercises y'all, and it is making them hate us for no benefit," tweeted Matt Linton, a security incident manager at Google.

Linton also published a post on the Google Security blog about the pitfalls of today's simulated phishing tests. The company is required to send fake phishing emails to its employees to meet the US government's security compliance requirements. In these tests, Google sends an employee a phishing email. If the worker clicks a link in the email, they'll be told they failed the test and will usually be required to take some sort of training course. However, Linton argues that simulated phishing tests can lead to harmful side effects, which can undermine a company's security. "There is no evidence that the tests result in fewer incidences of successful phishing campaigns," Linton said, noting that phishing attacks continue to help hackers gain a foothold inside networks, despite such training. He also pointed to a 2021 study that ran for 15 months and concluded that these phishing tests don't "make employees more resilient to phishing."

RISC-V Now Supports Rust In the Linux Kernel (phoronix.com) 31

Michael Larabel reports via Phoronix: The latest RISC-V port updates have been merged for the in-development Linux 6.10 kernel. Most notable with today's RISC-V merge to Linux 6.10 is now supporting the Rust programming language within the Linux kernel. RISC-V joins the likes of x86_64, LoongArch, and ARM64 already supporting the use of the in-kernel Rust language support. The use of Rust within the mainline Linux kernel is still rather limited with just a few basic drivers so far and a lot of infrastructure work taking place, but there are a number of new drivers and other subsystem support on the horizon. RISC-V now supporting Rust within the Linux kernel will become more important moving forward.

The RISC-V updates for Linux 6.10 also add byte/half-word compare-and-exchange, support for Zihintpause within hwprobe, a PR_RISCV_SET_ICACHE_FLUSH_CTX prctl(), and support for lockless lockrefs. More details on these RISC-V updates for Linux 6.10 via this Git merge.

Hopes For Sustainable Jet Fuel Not Realistic, Report Finds (theguardian.com) 170

An anonymous reader quotes a report from The Guardian: Hopes that replacement fuels for airplanes will slash carbon pollution are misguided and support for these alternatives could even worsen the climate crisis, a new report has warned. There is currently "no realistic or scalable alternative" to standard kerosene-based jet fuels, and touted "sustainable aviation fuels" are well off track to replace them in a timeframe needed to avert dangerous climate change, despite public subsidies, the report by the Institute for Policy Studies, a progressive thinktank, found. "While there are kernels of possibility, we should bring a high level of skepticism to the claims that alternative fuels will be a timely substitute for kerosene-based jet fuels," the report said. [...]

In the U.S., Joe Biden's administration has set a goal for 3 billion gallons of sustainable aviation fuel, which is made from non-petroleum sources such as food waste, woody biomass and other feedstocks, to be produced by 2030, which it said will cut aviation's planet-heating emissions by 20%. [...] Burning sustainable aviation fuels still emits some carbon dioxide, while the land use changes needed to produce the fuels can also lead to increased pollution. Ethanol biofuel, made from corn, is used in these fuels, and meeting the Biden administration's production goal, the report found, would require 114m acres of corn in the U.S., about a 20% increase in current land area given over to to the crop. In the UK, meanwhile, 50% of all agricultural land will have to be given up to sustain current flight passenger levels if jet fuel was entirely replaced. "Agricultural land use changes could threaten global food security as well as nature-based carbon sequestration solutions such as the preservation of forests and wetlands," the report states. "As such, SAF production may actively undermine the Paris agreement goal of achieving greatly reduced emissions by 2050."
Chuck Collins, co-author of the report, said: "To bring these fuels to the scale needed would require massive subsidies, the trade-offs would be unacceptable and would take resources aware from more urgent decarbonization priorities."

"It's a huge greenwashing exercise by the aviation industry. It's magical thinking that they will be able to do this."

Phil Ansell, director of the Center for Sustainable Aviation at the University of Illinois, added: "There's an underappreciation of how big the energy problem is for aviation. We are still many years away from zero pollution flights. But it's true that the industry has been slow to pick things up. We are now trying to find solutions, but we are working at this problem and realizing it's a lot harder than we thought. We are late to the game. We are in the dark ages in terms of sustainability, compared to other sectors."
