Bill Gates argues that when it comes to climate change, "there are more reasons to be hopeful than many people realize — and it's not just that renewable energy sources like wind and solar are getting cheaper.

"And it's not just because many of the steps already taken to reduce carbon emissions are working: Carbon emissions from fossil fuels will probably peak in 2025." The main thing that makes me optimistic is all the innovation I'm seeing. As someone who has been funding climate solutions for years, I get to learn from ingenious scientists who are working on ideas that will help the world solve climate change. And their work makes me confident that innovation will help the world get on track to meet its climate goals.

Some people are skeptical when a technology person like me says innovation is the answer. And it's true that new tools aren't the only thing we need. But we won't solve the climate problem without them.

There are two reasons for this. First, we need to eliminate emissions from every sector of the economy. Although some behavior change will help, the world can't achieve its zero-emissions goals without inventing new ways of doing things. For example, the production of concrete and steel alone accounts for around 10 percent of the world's annual greenhouse gases, but right now, we don't have practical ways to make either one without releasing carbon dioxide.

The second reason is that, in a world with limited resources, innovations allow us to magnify the impact of our efforts... We couldn't solve the climate problem with existing technology even if we had unlimited resources — and, of course, we don't have unlimited resources. So we need to be as rigorous as possible about doing the most good with the funding that is available. In my view, that boils down to inventing and deploying new ways to cut emissions and to help people survive and thrive in a warming world.
Gates believes we're at "the beginning of a Clean Industrial Revolution" --pointing readers to Breakthrough Energy's recent State of the Transition Report for more details.

But Gates also provides some specific examples of optimism-fuleing breakthroughs"

• "To reduce emissions, we need to replace the synthetic fertilizers that release nitrous oxide, a greenhouse gas, when broken down by microbes in the soil; Pivot Bio has genetically modified microbes to provide plants with the nitrogen they need without the excess greenhouse gases that synthetic alternatives produce."

• "Cement and steel are two of the biggest sources of emissions in this category. Boston Metal is well on the way to making steel with electricity (which can be generated without emissions) instead of coal. CarbonCure and Ecocem have developed low-carbon processes for making cement, and Brimstone has a way to do it while actually removing carbon from the air."

• "Because of inefficient windows and gaps in what's known as the building envelope, as much as 40% of heated or cooled air leaks out of the typical building. If we can drive that number down, buildings will require less heating and cooling — which will substantially lower our emissions. Aeroseal has developed a polymer that can seal ducts and other crevices; more than a quarter of a million buildings in the U.S. and Canada are already using their product. Another company, Luxwall, has developed a window that's many times more efficient than the single-pane windows used in most buildings. And unlike double-paned windows, it's thin enough to replace single-paned glass without having to rebuild the frame."

"NFTs aren't gone yet," writes the Verge.

"Disney will launch an 'all-new socially driven collectible experience' called Disney Pinnacle later this year, turning characters from Pixar, Star Wars, and its classic animated films into tradable digital pins." While announcing Pinnacle, Disney and its partner Dapper Labs won't even say the word "NFT." Dapper Labs still calls itself "the NFT company," but between a variety of scams, an eye-blistering episode at a recent Bored Ape event, and a market that has plunged since peaking in early 2021, that's a term they apparently will steer clear of. The only thing available on the site right now is a privacy policy that makes clear this is a Dapper Labs effort that's licensing content from Disney — not an in-house effort on the level of Disney Plus.

The NFT collection is being launched through an iOS app, and a spokesperson tells CoinDesk that web and Android applications will come later.
The Disney Pinnacle website has a few seconds of background animation showing the pins — and, of course, a waitlist signup form.

"At least 44,500 space objects now circle Earth," reports the New York Times magazine, "including 9,000 active satellites and 19,000 significant pieces of debris."

The article notes a threat assessment from U.S. Space Force Chief Master Sergeant Ron Lerch: What's most concerning isn't the swarm of satellites but the types. "We know that there are kinetic kill vehicles," Lerch said — for example, a Russian "nesting doll" satellite, in which a big satellite releases a tiny one and the tiny one releases a mechanism that can strike and damage another satellite. There are machines with the ability to cast nets and extend grappling hooks, too. China, whose presence in space now far outpaces Russia's, is launching unmanned "space planes" into orbit, testing potentially unbreakable quantum communication links and adding A.I. capabilities to satellites.

An intelligence report, Lerch said, predicted the advent, within the next decade, of satellites with radio-frequency jammers, chemical sprayers and lasers that blind and disable the competition. All this would be in addition to the cyberwarfare tools, electromagnetic instruments and "ASAT" antisatellite missiles that already exist on the ground. In Lerch's assessment, space looked less like a grand "new ocean" for exploration — phrasing meant to induce wonder that has lingered from the Kennedy administration — and more like a robotic battlefield, where the conflicts raging on Earth would soon extend ever upward.
One interesting detail from the article. "[I]f a requirement to 'blind and deafen' an enemy's satellites were to arise from U.S. Space Command, the Space Force could help fulfill the order. The means would most likely not be "kinetic" — some form of physical or explosive contact — but electronic, a weapon of code-related stealth, or perhaps a kind of debilitating high-energy burst."

And Space Force's highest-ranking officer, General Chance Saltzman, describes the kind of new military calculations made, for example, when Ukraine moved its communications to Starlink satellites: "The Russians are trying to interrupt it," he said, "and they're not having very good success." And the takeaway is that proliferated systems of many small machines in low orbit can be more technologically resilient to hacking and disruption than a few big machines in higher orbits... [W]hile small satellites in a large configuration could potentially be a more expensive investment than two or three megasatellites, the shift could be worthwhile. If an adversary believes that it cannot achieve a military objective, Saltzman remarked, it will hesitate to cross "a threshold of violence." No conflicts. No debris. No crisis.

According to a new study published in JAMA Internal Medicine, women in the U.S. are now projected to live about six years longer than U.S. men. TIME reports: [T]he 2021 data represent the largest gender-based life expectancy gap in the U.S. since 1996. The gulf began to widen before the COVID-19 pandemic, the authors note, but the trend accelerated from 2019 to 2021. Deaths from COVID-19 and unintentional injuries, a category that includes accidental drug overdoses, were the largest contributors to the widening of the gap, but differential rates of homicide, heart disease, and suicide deaths also played a role, according to the report. It's well-established that men die of these causes more frequently than women, and in recent years, they have been some of the most common causes of death overall. Heart disease, COVID-19, and unintentional injuries accounted for three of the top five in 2021.

The gender gap would have been even wider, the authors note, but for factors including increases in maternal mortality and decreases in cancer deaths among men. Overall, the data underscore the continued importance of limiting COVID-19's spread, and of finding better ways to improve national mental health and prevent drug overdoses and suicides -- fatalities sometimes labeled by experts as "deaths of despair."

The newly updated U.S. Department of Agriculture's "plant hardiness zone map" has gardeners across the nation researching what new plants they can grow in their warming regions, as the 2023 map is about 2.5 degrees Fahrenheit warmer than the 2012 map. NPR reports: This week the map got its first update in more than a decade, and the outlook for many gardens looks warmer. The 2023 map is about 2.5 degrees Fahrenheit warmer than the 2012 map across the contiguous U.S., says Chris Daly, director of the PRISM Climate Group at Oregon State University that jointly developed the map with the USDA. Daly says the new map means about half the country has shifted into a new half zone and half hasn't. In some locations, people may find they can grow new types of flowers, fruits, vegetables and plants.

Daly says he is hesitant to explicitly attribute the specific changes from the 2012 map to the 2023 map to climate change because of the volatility of the key statistic they used to create this map. They were mapping "the coldest night of the year, each year, over the past 30 years", Daly says, and it's a highly variable figure. In an email, a press officer for the USDA says, "Changes to plant hardiness zones are not necessarily reflective of global climate change because of the highly variable nature of the extreme minimum temperature of the year." But Daly says, in the big picture, climate change is playing a role in changing what grows where in the US: "Over the long run, we will expect to see a slow shifting northward of zones as climate change takes hold."

A court in Canada struck down a regulation classifying some plastic products as toxic, "a ruling that could hurt a push by Ottawa to ban single-use plastic items like bags, straws and forks." From the report: A ban on manufacturing and importing "harmful" single-use plastics came into effect last December after the federal government formally drew up a order that added them to a list of toxic items. But the Federal Court in Ottawa overturned that decision, calling the listing "unreasonable and unconstitutional." The case was brought by plastics manufacturers such as Dow Inc as well as Imperial Oil.

The office of Environment Minister Stephen Guilbeault said it was considering an appeal. "We strongly believe in taking action to tackle this crisis and keep millions of garbage bags worth of trash off our beaches, out of our waters, and away from nature," spokeswoman Kaitlin Power said in a statement.

Sam Altman has been fired as CEO of OpenAI, the company announced on Friday. Slashdot reader tagous submitted this statement from OpenAI's board: Mr. Altman's departure follows a deliberative review process by the board, which concluded that he was not consistently candid in his communications with the board, hindering its ability to exercise its responsibilities. The board no longer has confidence in his ability to continue leading OpenAI. The Verge reports: Chief technology officer Mira Murati will be the interim CEO, effective immediately. The company will be conducting a search for the permanent CEO successor. Employees at OpenAI found out about the news when it was announced publicly, according to multiple sources. This is an extremely sudden turn of events as Altman has largely been the face of OpenAI, which arguably kickstarted the current AI arms race with last year's hugely popular ChatGPT. Just last week, Altman keynoted at the company's DevDay conference, where it announced a suite of major new updates to compete with other big tech companies like Microsoft and Google. Altman also spoke at Thursday's Asia-Pacific Economic Cooperation conference. "I loved my time at OpenAI," Altman said in a post on X. "It was transformative for me personally, and hopefully the world a little bit. Most of all I loved working with such talented people. Will have more to say about what's next later."

UPDATE: OpenAI President Greg Brockman and three senior researchers at OpenAI resigned. According to The Information, Brockman "helped launch the artificial intelligence developer and has been key to developing ChatGPT and other core products." He was also a "member of the six-member board that fired Altman."

Tech reporter Kara Swisher writes that there was a conflict between "the profit direction of the company under Altman and the speed of development, which could be seen as too risky, and the nonprofit side dedicated to more safety and caution.... One person on the Sam side called it a 'coup,' while another said it was the the right move."

After months of wrangling, the European Commission says it has decided to renew the license for the weedkiller compound glyphosate, approving its use in European Union countries for ten more years. From a report: Following the decision yesterday, the Commission released a statement saying that, on the basis of comprehensive safety assessments carried out by the European Food Safety Authority (EFSA) and the European Chemicals Agency (ECHA), it would renew the licence, "subject to certain new conditions and restrictions." These include a ban on the use of the chemical to dry crops before harvest, and "the need for certain measures to protect non-target organisms." Governments can still restrict the use of glyphosate in their own countries if they consider the risks too high, particularly in regard to the need to protect biodiversity, the statement added.

Glyphosate is the active ingredient in Roundup, the world's most widely used herbicide. Over the years, a debate has developed about whether the chemical is safe to use on food crops, as well as its possible environmental impacts. Some studies point to a link between glyphosate and certain cancers; others suggest that the way in which it is used should not harm consumers. Glyphosate has been investigated extensively by food- and chemicals-safety agencies, but disagreements among researchers remain. The license allowing glyphosate's use in the EU was last renewed for five years in 2017. Ahead of the authorization's expiry in last December, the European Union temporarily extended it for another year to allow the EFSA to assess some 2,400 studies about the compound and to make a recommendation to governments.

The way we buy and sell homes in the U.S. isn't normal -- at least not compared with the rest of the world. From a report: The commission on a home sale here is typically around 5% to 6%, usually split between the seller's and buyer's agents. In most countries, the commissions are substantially smaller. The U.S. is home to as many as three million agents. By most estimates, no other country is even a close second.

Though it is unclear how much a court decision on commissions last month will upend American real estate, if at all, the ruling opens up the possibility of forever changing how agents are paid for their work. And looking at home sales around the world offers a window into what could be in store. One reason commissions here remain high is the use of buyer agents, said Ryan Tomasello, managing director at investment bank Keefe, Bruyette & Woods. Home sellers pay the commission -- typically between 5% and 6% of a home's selling price -- which is usually split between the seller's and buyer's agent. Buyer agents aren't nearly as common in other parts of the world, said Tomasello.

[...] In the pre-internet days, a buyer agent's main job was to screen and filter listings for hopeful home buyers. Today, much of that early house hunting can be done online. So the role of the buyer agent has shifted more to providing advice and support, as well as recommendations for home inspectors, lenders and lawyers. A good buyer agent will know how to make a strong offer and may push to lower the home price. In most countries, buyer agents are much less of a factor.

Sara Fischer reports via Axios: The decline of local newspapers accelerated so rapidly in 2023 that analysts now believe the U.S. will have lost one-third of the newspapers it had as of 2005 by the end of next year -- rather than in 2025, as originally predicted. There are roughly 6,000 newspapers left in America, down from 8,891 in 2005, according to a new report from Northwestern's Medill School of Journalism, Media, Integrated Marketing Communications. "We're almost at a one-third loss now and we'll certainly hit that pace next year," said the report's co-authors -- Penelope Muse Abernathy, a visiting professor at Medill, and Sarah Stonbely, director of Medill's State of Local News Project. Of the papers that still survive, a majority (4,790) publish weekly, not daily.

Over the past two years, newspapers continued to vanish at an average rate of more than two per week, leaving 204 U.S. counties, or 6.4%, without any local news outlet. Roughly half of all U.S. counties (1,562) are now only served with one remaining local news source -- typically a weekly newspaper. Abernathy and Stonbely estimate that 228 of those 1,562 counties, or roughly 7% of all U.S. counties, are at high risk of losing their last remaining local news outlet.

There isn't enough investment in digital news replacements to stop the spread of news deserts in America. The footprint for alternative local news outlets is tiny and they are mostly clustered around metro areas that already have some local coverage. The report estimates that -- for outlets focused on state and local news -- there are roughly 550 digital-only news sites, 720 ethnic media organizations and 215 public broadcasting stations in America, compared to 6,000 newspapers. The authors argue that the dynamic between those with access to quality local news and those who don't "poses a far-reaching crisis for our democracy as it simultaneously struggles with political polarization, a lack of civic engagement and the proliferation of misinformation and information online."

Google has announced that its News app and news.google.com will remove support for paid magazines next month. "The removal not only applies to new subscriptions/purchases, but also to existing libraries of magazines," reports 9to5Google. "That means that users who have paid for magazines to use them in the Google News app will be cut off pretty soon." From the report: Ahead of the December 18 shutdown, users will be able to export copies of paid magazines. Magazines that cannot be exported due to interactive elements will be eligible for a refund. Google explains: "Support for magazine content in Google News is being discontinued beginning on December 18, 2023, which means if you previously purchased or subscribed to magazines, access from Google News apps or news.google.com to your library of magazines will be removed. To continue to access previously purchased magazine content, we are providing the opportunity to export and save each purchased issue. In some cases, purchased magazines contain interactive elements that cannot be downloaded and saved for future access, and we are offering a refund for this content."

The company further adds that affected users will receive an email titled "An update to Google News magazine support" which will contain instructions on how to download copies of magazines they've paid for. However, the cutoff for downloads and/or refunds is also December 18, 2023, which means the clock is ticking. You can access your library of magazines on News here.

The UK has said it will refrain from regulating the British artificial intelligence sector, even as the EU, US and China push forward with new measures. From a report: The UK's first minister for AI and intellectual property, Viscount Jonathan Camrose, said at a Financial Times conference on Thursday that there would be no UK law on AI "in the short term" because the government was concerned that heavy-handed regulation could curb industry growth. The announcement comes as executives and policymakers around the world debate how to regulate the emerging technology, which holds the promise of transforming many industries and driven the rise in large tech company valuations over the past year.

The EU has led the field, with its legislation on AI regulation expected to come into force before the end of this year. Beijing is also implementing measures to regulate the industry, while US President Joe Biden recently issued an executive order to promote "responsible innovation." Camrose added: "I would never criticise any other nation's act on this. But there is always a risk of premature regulation." In rushing to introduce industry controls, "you are not actually making anybody as safe as it sounds," he said. "You are stifling innovation, and innovation is a very very important part of the AI equation."

Britain's drugs regulator has approved a groundbreaking treatment for two painful and debilitating lifelong blood disorders, which works by "editing" the gene that causes them. From a report: The Medicines and Healthcare products Regulatory Agency (MHRA) has given the green light for Casgevy to be used to treat sickle cell disease and beta thalassemia. It is the first medicine licensed anywhere that works by deploying gene editing that uses the "genetic scissors," known as CRISPR, for which its inventors won the Nobel prize for chemistry.

Casgevy's developers hope the pioneering treatment could banish the pain, infections and anaemia sickle cell disease brings and the severe anaemia experienced by those with beta thalassemia. About 15,000 people in the UK, almost all of African or Caribbean heritage, have sickle cell disease. About 1,000 -- mainly of Mediterranean, south Asian, south-east Asian and Middle Eastern background -- have beta thalassemia and need regular blood transfusions to treat their anaemia. Experts in the illnesses hope Casgevy may be a cure, making it no longer necessary for people with the conditions to have a bone marrow transplant. Until now this has been the only treatment available, even though the body can reject the donor marrow. The Sickle Cell Society welcomed the MHRA's decision as a "historic moment for the sickle cell community" which "offers [them] newfound hope and optimism."

An anonymous reader quotes a report from The Verge: The Federal Communications Commission has approved (PDF) a new set of rules aiming to prevent "digital discrimination." It means the agency can hold telecom companies accountable for digitally discriminating against customers -- or giving certain communities poorer service (or none at all) based on income level, race, or religion. The new rules come as part of the Biden Administration's 2021 Bipartisan Infrastructure Law, which requires the FCC to develop and adopt anti-digital discrimination rules. "Many of the communities that lack adequate access to broadband today are the same areas that suffer from longstanding patterns of residential segregation and economic disadvantage," FCC Chairwoman Jessica Rosenworcel said following today's vote. "It shows that minority status and income correlate with broadband access."

Under the new rules, the FCC can fine telecom companies for not providing equal connectivity to different communities "without adequate justification," such as financial or technical challenges of building out service in a particular area. The rules are specifically designed to address correlations between household income, race, and internet speed. Last year, a joint report from The Markup and the Associated Press found that AT&T, Verizon, and other internet service providers offer different speeds depending on the neighborhood in cities throughout the US. The report revealed neighborhoods with lower incomes and fewer white people get stuck with slower internet while still having to pay the same price as those with faster speeds. At the time, USTelecom, an organization that represents major telecom providers, blamed the higher price on having to maintain older equipment in certain communities.

The FCC was nearly divided on the new set of rules, as it passed with a 3-2 vote. Critics of the new policy argue the rules are an overextension of the FCC's power. Jonathan Spalter, the CEO of USTelecom, says the FCC is "taking overly intrusive, unworkably vague, and ultimately harmful steps in the wrong direction." Spalter adds the framework "is counter" to Congress' goal of giving customers equal access to the internet. Still, supporters of the new rules believe they can go a long way toward improving fractured broadband coverage throughout the US. The FCC will also establish an "improved" customer portal, where the agency will field and review complaints about digital discrimination. It will take things like broadband deployment, network upgrades, and maintenance across communities into account when evaluating providers for potential rule violations, giving it the authority to hopefully finally address the disparities in internet access throughout the US.

Simon Jack reports via the BBC: The price paid to generate electricity by offshore wind farms is set to rise by more than 50% as the government tries to entice energy firms to invest. Its comes after an auction for offshore wind projects failed to attract any bids, with firms arguing the price set for electricity generated was too low. The BBC understands the government now will raise the price it pays from 44 pounds per MWh to as much as 70 pounds. It is hoped more offshore wind capacity will lead to cheaper energy bills. Energy companies have told the BBC that electricity produced out at sea would remain cheaper and less prone to shock increases compared to power derived from gas-fired power stations.

The UK is a world leader in offshore wind and is home to the world's four largest farms, supporting tens of thousands of jobs, which provided 13.8% of the UK's electricity generation last year, according to government statistics. But when the government revealed in September that no companies bid for project contracts, plans to nearly quadruple offshore wind capacity from 13 gigawatts GW to 50 by 2030 -- enough to power every home in the UK -- were dealt a heavy blow.

The technology has been described as the "jewel in the UK's renewable energy crown," but firms have been hit by higher costs for building offshore farms, with materials such as steel and labour being more expensive. According to energy companies, the government's failure to recognize the impact of higher costs led some firms to abandon existing projects, and all operators to boycott the most recent auction.

Lauren Irwin reports via The Hill: Google agreed to pay $8 billion over four years to Samsung to make its apps default on Samsung phones, according to information presented by Epic Games in court. James Kolotouros, vice president for partnerships at Google, testified Monday in a San Francisco trial, saying that the company and Samsung were to share app store revenue to ensure Android mobile devices came with Google Play preinstalled. Epic, the company that makes the popular video game "Fortnite," sued Google in 2020, alleging the company's app marketplace violates antitrust laws.

Epic is trying to show that Google executives have discouraged third-party app stores on Samsung devices so it wouldn't cut into the profit of Google Play, Bloomberg reported. According to Kolotouros's testimony, half or more of Google Play revenue comes from Samsung devices. The trial targets the app store that distributes apps for the company's Android software, which powers virtually all the world's smartphones that aren't made by Apple.

Epic alleges Google has created an illegal monopoly on Android apps so it can boost its profits through commissions, ranging from 15 to 30 percent on purchases made within an app. Google argues it was doing so to compete with Apple and its app store, an argument attacked by Epic attorney Lauren Moskowitz. Earlier in the trial, Google's attorney said the company can't be a monopoly because it faces competition from companies such as Apple.

Michael Larabel reports via Phoronix: Guardrails have been in place where the Firefox browser has enabled Wayland by default (when running on recent GTK versions) but as of today that code has been removed... Firefox will try to move forward with stable releases where Wayland will ship by default! Mozilla Bug 1752398 to "ship the Wayland backend to release" has been closed this evening! After the ticket was open for the past two years, it's now deemed ready to hopefully ship enabled for Firefox 121!

This patch drops the "early beta or earlier" check to let Wayland support be enabled by default when running on recent GTK versions (GTK 3.24.30 threshold). Firefox 121 is due for release around 19 December and if all continues to hold, it will finally ship with the Wayland back-end enabled by default as another big step forward.

The EU has struck a deal that will force the fossil fuel industry to rein in dangerous methane pollution. From a report: Under the proposed law, which is the first of its kind, coal, oil and gas companies would be required to report their methane emissions and take steps to avoid them. The measures include finding and fixing leaks, and limiting wasteful practices such as venting and flaring gas by 2027. Jutta Paulus, a German MEP with the Green grouping who worked on the proposal, said: "Finally, the EU tackles the second most important greenhouse gas with ambitious measures. Less methane emissions mean more climate protection and more energy sovereignty."

Methane has more than 80 times the global heating power of carbon dioxide over a 20-year timespan but does not last as long in the atmosphere. Cutting methane emissions is seen as a cheap and easy way to stop extreme weather growing more violent in the short-term. The new EU rules, which were agreed on Wednesday by the European parliament and European Council, mean fossil fuel companies must try to repair leaks no more than five days after finding them, and fully fix them within a month. By the end of next year, operators will have to survey their existing sites and submit action plans to find and fix methane leaks.

An anonymous reader quotes a report from the New York Times: On Oct. 9, 2022, telescopes in space picked up a jet of high energy photons careening through the cosmos toward Earth, evidence of a supernova exploding 1.9 billion light-years away. Such events are known as gamma ray bursts, and astronomers who have continued studying this one said it was the "brightest of all time." Now, a team of scientists have discovered that this burst caused a measurable change in the number of ionized particles found in Earth's upper atmosphere, including ozone molecules, which readily absorb harmful solar radiation.

"The ozone was partially depleted -- was destroyed temporarily," said Pietro Ubertini, an astronomer at the National Institute of Astrophysics in Rome who was involved in discovering the atmospheric event. The effect was detectable for just a few minutes before the ozone repaired itself, so it was "nothing serious," Dr. Ubertini said. But had the supernova occurred closer to us, he said, "it would be a catastrophe." The discovery, reported Tuesday in a paper published in the journal Nature Communications, demonstrates how even explosions that occur far from our solar system can influence the atmosphere, which can be used as a giant detector for extreme cosmic phenomena.

To study the effects of last year's gamma ray burst on Earth, Dr. Ubertini and his colleagues looked for signals at the top of the ionosphere using data from the China Seismo-Electromagnetic Satellite, an orbiter designed to study changes in the atmosphere during earthquakes. They identified a sharp jump in the electric field at the top of the ionosphere, which they correlated to the gamma ray burst signal measured by the European Space Agency's International Gamma-Ray Astrophysics Laboratory, a mission that launched in 2002 to observe radiation from faraway celestial objects. The researchers found that the electric field rose by a factor of 60 as gamma rays ionized (essentially knocking away electrons from) ozone and nitrogen molecules high in the atmosphere. Once ionized, the molecule is unable to absorb any ultraviolet radiation, temporarily exposing Earth to more of the sun's damaging rays.

Sarah Perez reports via TechCrunch: YouTube today announced how it will approach handling AI-created content on its platform with a range of new policies surrounding responsible disclosure as well as new tools for requesting the removal of deepfakes, among other things. The company says that, although it already has policies that prohibit manipulated media, AI necessitated the creation of new policies because of its potential to mislead viewers if they don't know the video has been "altered or synthetically created." One of the changes that will roll out involves the creation of new disclosure requirements for YouTube creators. Now, they'll have to disclose when they've created altered or synthetic content that appears realistic, including videos made with AI tools. For instance, this disclosure would be used if a creator uploads a video that appears to depict a real-world event that never happened, or shows someone saying something they never said or doing something they never did.

It's worth pointing out that this disclosure is limited to content that "appears realistic," and is not a blanket disclosure requirement on all synthetic video made via AI. "We want viewers to have context when they're viewing realistic content, including when AI tools or other synthetic alterations have been used to generate it," YouTube spokesperson Jack Malon told TechCrunch. "This is especially important when content discusses sensitive topics, like elections or ongoing conflicts," he noted. [...] The company also warns that creators who don't properly disclose their use of AI consistently will be subject to "content removal, suspension from the YouTube Partner Program, or other penalties." YouTube says it will work with creators to make sure they understand the requirements before they go live. But it notes that some AI content, even if labeled, may be removed if it's used to show "realistic violence" if the goal is to shock or disgust viewers. [...]

Other changes include the ability for any YouTube user to request the removal of AI-generated or other synthetic or altered content that simulates an identifiable individual -- aka a deepfake -- including their face or voice. But, the company clarifies that not all flagged content will be removed, making room for parody or satire. It also says that it will consider whether or not the person requesting the removal can be uniquely identified or whether the video features a public official or other well-known individual, in which case "there may be a higher bar," YouTube says. Alongside the deepfake request removal tool, the company is introducing a new ability that will allow music partners to request the removal of AI-generated music that mimics an artist's singing or rapping voice.
