Research indicates that carbon dioxide removal plans will not be enough to meet Paris treaty goals

New research conducted by the University of East Anglia (UEA) suggests that current carbon removal plans will not be enough to comply with Paris treaty goals to limit global warming to 1.5C, as reported in a study published by Nature. Scientists came to this conclusion by measuring the “emissions gap” between various national climate protection plans and what is actually needed to reach that goal.

This first-of-its-kind study found a gap of up to 3.2 billion tons of carbon dioxide (CO2) between current global plans to remove carbon from the atmosphere and what’s needed by 2050 to avoid the worst impacts of global warming. These impacts include heatwaves, floods, droughts, melting ice and sea level rise.

Since 2010, the United Nations environmental organization UNEP has taken similar measurements of this emissions gap. UEA’s research, which focuses primarily on CO2 removal, indicates that climate policy requires a more ambitious scope if we are to, well, survive as a species.

This means a more nuanced and robust approach that still keeps current carbon removal practices in place, but with a renewed focus on cutting emissions, renewable energy and minimizing deforestation. There are also novel carbon removal options that many nations have been slow to discuss, let alone implement.

These include advanced air filters systems and enhanced rock weathering. The latter is a technique in which carbon is removed from the atmosphere and stored in rocks. These techniques account for the removal of just 0.002 billion tons of C02 per year, compared to 3 billion tons through conventional options. The research indicates that these novel options must become more prevalent in the coming years to help meet that 1.5C threshold.

“The calculation should certainly be refined,” said the study’s lead author, Dr. William Lamb, of the MCC Applied Sustainability Science working group. “This much is clear: without a rapid reduction in emissions towards zero, across all sectors, the 1.5C limit will not be met under any circumstances.”

Co-author Dr. Naomi Vaughan, of the Tyndall Centre for Climate Change Research at UEA, added that “countries need more awareness, ambition and action on scaling up carbon dioxide removal methods together with deep emissions reductions to achieve the aspirations of the Paris Agreement.”

To that end, even if every country sticks to promises regarding carbon removal targets, the amount of carbon removed would likely increase by a maximum of 0.5 billion tons by 2030 and 1.9 billion tons by 2050. The latest Intergovernmental Panel on Climate Change (IPCC) reported that it would take a removal increase of 5.1 billion tons to avoid the worst effects of climate change. So, yeah, there’s that gap of 3.2 billion tons.

We aren’t doomed, at least not yet anyways. The IPCC suggests an alternative scenario in which the world’s governments work together to reduce global energy demand, hastened by “politically initiated behavior.” In this scenario, carbon removal would increase by 2.5 billion tons by 2050 and alternative methods would help tighten the emissions gap to just 400 million tons. So we basically have to shift our entire society from one of self interest to one of global cooperation. It never hurts to dream and, hey, maybe AI will swoop in and save us.

Boeing’s Starliner spacecraft may finally take its first crewed flight next week

Boeing’s Starliner crew capsule, which has been plagued by years of setbacks and cost overruns amounting to roughly $1.5 billion, is about to take its first flight with humans on board. Boeing was chosen 10 years ago alongside SpaceX to develop a spacecraft that could ferry astronauts from US soil to the International Space Station (ISS), thus allowing NASA to end its reliance on Russia for crewed flights. The companies were each awarded a fixed-price contract under NASA’s Commercial Crew Program: $4.2 billion to Boeing for its CST-100 (Starliner) and $2.6 billion for SpaceX’s Crew Dragon.

Their initial deadline of 2017 proved to be a bit too ambitious. SpaceX managed its first crewed flight in 2020 — and about a dozen since — while Boeing has struggled to get its Starliner capsule off the ground. But as soon as May 6, it’ll finally have a crewed flight under its belt.

Starliner is now at Cape Canaveral Space Force Station’s Launch Complex-41 attached to the ULA Atlas V rocket that’ll send it on its way to the ISS. Liftoff is planned for 10:34PM ET on Monday, May 6. The capsule will be carrying two NASA astronauts: Butch Wilmore, the mission’s commander, and Suni Williams, who will serve as pilot.

NASA

Not only is it Starliner’s first crewed flight, but this test is only its third flight ever. The spacecraft (without anyone aboard) successfully demonstrated its ability to reach, dock and undock from the ISS in spring 2022 when it conducted its second Orbital Flight Test. On its previous attempt, in 2019, Starliner failed to make it all the way to the ISS thanks to a software issue that resulted in it burning too much fuel (one of a few problems Boeing missed after it opted at the time not to do end-to-end testing).

It’s suffered numerous other problems, too, in the years since Boeing bagged the NASA contract, causing the company to slip far behind SpaceX. There was a toxic fuel leak during a 2018 test. Then corrosion caused valves in the propulsion system to stick, waylaying Boeing’s plans for a 2021 launch, as Ars Technica reported earlier this year. Problems with the spacecraft’s parachute deployment system derailed plans for a launch last summer, and the team had to remove around a mile of flammable tape.

Boeing has also had its fair share of troubles beyond Starliner during this time, facing increased scrutiny into the safety of its airplanes — particularly the 737 Max line — after two fatal crashes in 2018 and 2019, on top of other less serious incidents. Most recently, a panel blew off a 737 Max 9 mid-flight in January, forcing it to make an emergency landing.

The May 6 flight marks a major step toward Starliner’s certification as a crew transport system that NASA can actually put into its rotation for trips to the ISS. That will give the space agency the redundancy it’s looking for; with both Crew Dragon and Starliner in operation, it’ll always have a backup option in case something happens to one of them. Both NASA and Boeing have been adamant that the capsule has been put through an exhaustive review process and is ready to support astronauts. NASA wrapped up its Crew Flight Test Readiness Review of Starliner on April 25.

“The first crewed flight of a new spacecraft is an absolutely critical milestone,” NASA associate administrator Jim Free said during a briefing on the completion of the review. “The lives of our crewmembers Suni Williams and Butch Wilmore are at stake — we don’t take that lightly at all.” The latest review is “the culmination of a detailed review season that has really thoroughly established that we are really ready to go on this flight,” said NASA chief flight director Emily Nelson.

NASA/Frank Michaux

It’s expected to take about 24 hours for Starliner to reach the ISS after it lifts off, and as this is a test flight, its onboard crew will have a lengthy task list of systems and equipment checks to complete across every phase of the journey. While Starliner can operate autonomously, the crew will test its manual controls and make sure it’s in good shape for manual abort scenarios. After Starliner docks to the space station, the astronauts will spend about a week there working with the current crew, Expedition 71.

Then, they’ll undock from the orbiting lab and head home — and put Starliner through the test of reentry and landing. A few potential landing sites in the southwest US have been picked out, including the White Sands Missile Range in New Mexico.

Wilmore and Williams have been training for Starliner’s first flight for years. “They know the vehicle inside and out, and they’ve been part of the test environment that’s developed the Starliner capability,” said Steve Stich, manager for NASA’s Commercial Crew Program. All involved in last Thursday’s briefing acknowledged that they may encounter some unexpected challenges, and that there’s much to be learned from this first crewed flight. “It’s a good reminder for all of us that the team has practiced, run sims, run models, but there’s nothing like flying in the space environment,” said Free.

The NASA and Boeing officials also expressed their confidence that the craft itself and the teams handling its journey are well-prepared for the job. The astronauts echoed these sentiments upon arriving at the Kennedy Space Center in Florida. “We wouldn’t be here if it weren’t ready,” Wilmore said, addressing questions from the press. “We are ready, the spacecraft’s ready, and the teams are ready.”

If Starliner for whatever reason can’t launch on the 6th, it’ll have backup opportunities on May 7, 10 and 11. After the Crew Flight Test is complete and the astronauts are back home, NASA will get to work certifying the spacecraft for future missions bringing crews to and from the ISS. It’s currently targeting 2025 for Starliner to begin duty.

“I don’t want to get too far ahead because we still need to fly a successful mission,” said Free ahead of Starliner’s launch, “but when we do, and when we certify Starliner, the United States will have two unique human space transportations that provide critical redundancies for ISS access.”

Boom’s XB-1 supersonic jet has been authorized to break the speed of sound

Boom’s supersonic XB-1 test jet has received Federal Aviation Administration (FAA) approval to fly past Mach 1, the company announced. Tests are slated to take place later this year at the Black Mountain Supersonic Corridor in Mojave, CA, and the results could help prove the feasibility of the design in areas like fuel consumption, speeds and flight characteristics.

“Following XB-1’s successful first flight, I’m looking forward to its historic first supersonic flight,” said Boom Supersonic founder and CEO Blake Scholl. “We thank the Federal Aviation Administration for supporting innovation and enabling XB-1 to continue its important role of informing the future of supersonic travel.”

The approval arrives just weeks after a successful X-B1 test flight at subsonic speeds by a pair of test pilots. It follows a thorough review and environmental assessment, and mandates a chaise plane to trail the XB-1 to monitor and record flight safety, according to the company.

The company will conduct 10-20 flights before attempting to break the speed of sound. It will “systematically expand the flight envelope during that time” to confirm performance and handling qualities, Boom said, while performing in-flight checks of all systems and demonstrating a safe margin to flutter/vibration boundaries. Test pilot Tristan “Geppetto” Brandenberg will be at the controls during the first supersonic flight.

Passenger flights are still a long way off, though. The XB-1 is a scaled-down version of Boom’s ultimate goal, a commercial liner called Overture that’s expected to carry under 100 passenger at “business class” comfort levels. The company has said that plane will be able to fly from Tokyo to Seattle in four hours and thirty minutes.

The company has seen its share of issues, with test plans delayed and a rupture with original engine manufacturer Rolls-Royce. The company subsequently partnered with a company called FTT to develop its own custom “Symphony” jet engine. Still, the company already has customers lined up, with American Airlines and United Airlines having place orders for multiple jets.

NASA is also working on a supersonic jet called the X-59 with a reduced sonic profile, but Boom Supersonic hasn’t provided much detail on how it plans to reduce the, well, supersonic boom.

Google says Epic’s Play Store demands are too much and too self-serving

Epic Games won its antitrust lawsuit against Google in December when a federal jury found that the latter violated US antitrust laws with regards to how it runs the Play Store. A few months later, the gaming developer submitted its list of demands, which if implemented will blow the Play Store wide open. Now, Google has filed an injunction telling the court that no, it will not give Epic what it wants without a fight, because the company’s asks “stray far beyond the trial record.”

The remedies Epic had submitted would require the court not just to create a global regulatory regime to set prices for apps, Google wrote in the filing as seen by Engadget, but also to micromanage “a highly complex and dynamic ecosystem” used by billions of consumers and app developers around the world. If you’ll recall, Epic wants Google to open up Android to third-party app stores and to make its catalog of apps available to those stores. It also wants restrictions on pre-installed apps to be outlawed and to prohibit any Google activity that incentivizes third-parties.

Google said that bowing down to all those demands would “effectively prevent [it] from competing,” which in turn would negatively affect Android users and developers. Epic’s proposals only benefit Epic, Google said in its filing, and will harm other developers by depriving them of control over where their app is distributed. Manufacturers will no longer be able to take advantage of the partnerships Google typically offers, while users have to deal with additional security and privacy risks.

The company also slammed Epic over the “vagueness” of its proposed injunction, which would require the repeated and ongoing intervention of the courts. Similarly, Epic’s demands would apparently require the court to micromanage Google’s business.

“Epic’s demands would harm the privacy, security, and overall experience of consumers, developers, and device manufacturers,” Wilson White, Google’s Vice President of Government Affairs & Public Policy, told Engadget in a statement. “Not only does their proposal go far beyond the scope of the recent US trial verdict — which we will be challenging — it’s also unnecessary due to the settlement we reached last year with State Attorneys General from every state and multiple territories. We will continue to vigorously defend our right to a sustainable business model that enables us to keep people safe, partner with developers to innovate and grow their businesses, and maintain a thriving Android ecosystem for everyone.”

Google said that if Epic truly wants to promote competition rather than create “an unfair, court- supervised advantage for itself,” then it would take cues from its settlement with the state officials that previously accused the company of abusing its dominance on Android app distribution. Epic Games CEO Tim Sweeney was, unsurprisingly, unhappy with that settlement, tweeting at the time: “If Google is ending its payments monopoly without imposing a Google Tax on third party transactions, we’ll settle and be Google’s friend in their new era. But if the settlement merely pays off the other plaintiffs while leaving the Google Tax in place, we’ll fight on. Consumers only benefit if antitrust enforcement not only opens up markets, but also restores price competition.”

The Morning After: Peloton’s grim post-pandemic reality

Peloton had a great pandemic. It’s a weird thing to say, but the company’s premium exercise equipment (expanding from bikes to treadmills and even weight-training tech) were the hot workout-from-home products. That boom made some people (not normal, sensible people) suggest we were never going back to bricks-and-mortar gyms once the world reopened.

But… we went back. Now, Peloton’s latest financial numbers and statements are not great, and further cuts, nips and tucks are now on the cards. Its shares have gone from $156 in 2021 to less than $3 today. Peloton is laying off 15 percent of its workforce, shuttering more of its showrooms and getting rid of its CEO, again. It also killed Mr. Big.

The company says it’s planning to expand overseas (it’s gained a foothold in the UK), but it might just be a case of the company resizing to fit the reality of at-home fitness in 2024.

TikTok and Universal Music Group (UMG) have signed a deal so Taylor Swift, Olivia Rodrigo, The Weeknd and other artists can return to the platform. Universal pulled its song back in February. Now, a key part of the deal is artist protection from generative AI. “TikTok and UMG will work together to ensure AI development across the music industry will protect human artistry and the economics that flow to those artists and songwriters,” the companies wrote. Drake, also part of UMG, has had his own recent troubles with AI tools and music.

X is changing how the block button works

Blocking will no longer hide your replies.

Elon Musk is not a fan of the block button. The button (and feature) persists for now, but X is changing how it works. X is tweaking the visibility of replies in a block. Previously, a user could block someone on X and still reply to their posts. The blocked person wouldn’t be able to view that reply, but other X users could. It’s a black-belt passive-aggressive X move. Now, users see direct replies even if the person posting has blocked them.

Ubisoft’s first-person shooter XDefiant is launching on May 21

Tom Clancy’s XDefiant is almost upon us. Ubisoft is releasing the free-to-play first-person shooter on May 21 for the Xbox Series X|S, the PS5 and PC through Ubisoft Connect. The developer is kicking things off with the preseason version of the game, which is scheduled to last for six weeks before XDefiant’s first season officially starts. Ubisoft announced the game way back in 2021, promising team-based matches with a focus on gunplay that will include elements from other games in the Tom Clancy universe.

The preseason will offer five different game modes with 14 maps, 24 weapons and five playable factions inspired by Ubisoft’s other franchises. Players will need to choose their faction before the match begins and before they respawn. They must also choose their primary and secondary weapon — their options include assault rifles, submachine guns, shotguns and sniper rifles — and a grenade. To customize a weapon, they can add barrel and muzzle attachments, such as sights and grips.

Each faction will give players access to two active abilities, one passive buff and another ultra ability that they have to charge up while the match is ongoing. Libertad, one of the available factions, puts a focus on healing, while members of the Cleaners faction can use fire to burn their opponents. Echelon players can reveal enemy locations with their stealth technology, whereas Phantoms’ abilities can block damage. The last faction available, DedSec, is for those who want to play as hackers.

When the first season launches, Ubisoft is adding four new factions, 12 new weapons and 12 new maps to the game. According to the Year 1 roadmap the developer shared last year, it expects to roll out four seasons with the game’s first year, with each one adding more new content meant to keep players engaged, invested and more likely to come back and keep playing.

X is changing how the block button works

Elon Musk has made no secret that he’s not a fan of the block button. Now, X is changing how blocks work on its platform, though it’s (for now) stopping short of Musk’s wish of nuking the feature entirely.

Instead, X is tweaking the visibility of replies in the context of a block. Previously, a user could block someone on X and still reply to their posts. And the person who was blocked wouldn’t be able to view that reply or know the person who had blocked them was engaging with their posts. That’s now being rolled back so that users will be able to see direct replies even if the person posting has blocked them. In a post from X’s engineering team, the company said the change is “part of our ongoing commitment to aligning the block feature with our principles as a public town square.”

We are making changes to how block works.

If a user who has blocked you replies to one of your posts, you will now be able to see their reply. This change enables you to identify and report any potential bad content that you previously could not view, safeguarding both your…

— Engineering (@XEng) May 2, 2024

The post also hinted that there may be more changes coming to blocks, which is one of the most widely used safety features on the service. “Our goal is to allow users to control their experience while maintaining the public visibility of posts,” the company said. That would seem to align with previous comments from Musk, who has said on multiple occasions that a public-facing “block” feature “makes no sense” and that “block is going to be deleted as a ‘feature,’ except for DMs.”

For now, the changes to blocking aren’t that drastic. In fact, they may even be welcomed by some users who want more visibility into what people are saying about them on the platform. But the fact that X is starting to change the visibility of previously blocked content could also be a sign of more significant changes to come.

Microsoft’s latest Windows security updates might break your VPN

Microsoft says the April security updates for Windows may break your VPN. (Oops!) “Windows devices might face VPN connection failures after installing the April 2024 security update (KB5036893) or the April 2024 non-security preview update,” the company wrote in a status update. It’s working on a fix.

Bleeping Computer first reported the issue, which affects Windows 11, Windows 10 and Windows Server 2008 and later. User reports on Reddit are mixed, with some commenters saying their VPNs still work after installing the update and others claiming their encrypted connections were indeed borked.

“We are working on a resolution and will provide an update in an upcoming release,” Microsoft wrote.

There’s no proper fix until Microsoft pushes a patched update. However, you can work around the issue by uninstalling all the security updates. In an unfortunate bit of timing for CEO Satya Nadella, he said last week that he wants Microsoft to put “security above else.” I can’t imagine making customers (temporarily) choose between going without a VPN and losing the latest protection is what he had in mind.

At least one Redditor claims that uninstalling and reinstalling their VPN app fixed the problem for them, so it may be worth trying that before moving on to more drastic measures.

If you decide to uninstall the security updates, Microsoft tells you how. “To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument,” the company wrote in its patch notes. “You can find the package name by using this command: DISM /online /get-packages.”

Two of our top Anker power banks are back on sale at all-time low prices

Some of the best and brightest Anker power banks are on sale via Amazon and directly from the company. These deals include the 20,000mAh Prime portable charge, which is down to $90 from its usual price of $130. That’s a discount of 31 percent and matches a previous record low.

Anker products are all over our list of the best power banks, and we named the Prime charger as the best ultra-premium product on the market. Unfortunately, ultra-premium also means ultra-expensive, though $90 is a whole lot better than $130.

We admired the slick aesthetics, as power banks don’t tend to turn heads. The case is a textured metallic plastic with a nice polish. There’s a built-in screen and rounded corners, all of which work to give this bank a luxe feel. The screen is useful, displaying the remaining charge within the battery and the watts flowing out to each device. The charge times and capacity were in line with other 20K batteries we tested.

It’s easy to use, which is made even easier if people pony up for the companion base. This base includes magnets to align the pins, so users can just plop the battery down and move on to something else. The base does offer additional ports, one USB-A and two USB-C, which turns the whole package into a fairly decent power hub. However, the base costs $70 and isn’t currently on sale.

We did notice that the Prime charger can be sluggish to wake, which isn’t a huge deal. The power bank’s sleek and shiny finish also tends to pick up fingerprints. There’s a faux-suede pouch to carry it in, which is a nice touch.

The Anker Nano Battery is also on sale for $16 with an on-page coupon, which is $14 off the device’s list price. This cute little thing boasts a foldable USB-C connector, so as to better integrate with smartphones. It also made our list of the best power banks and we heartily recommend it for anyone looking for a quick partial charge of an Android device.
