An anonymous reader quotes a report from The Globe and Mail: A Saskatchewan judge says an emoji can amount to a contractual agreement and ordered a farmer to pay more than $82,000 for not delivering product to a grain buyer after responding to a text message with a thumbs-up image. The Court of King's Bench decision said a grain buyer with South West Terminal sent a text to farmers in March 2021 saying that the company was looking to buy 86 tons of flax for $17 per bushel to be delivered in the fall. The buyer, Kent Mickleborough, later spoke with Swift Current farmer Chris Achter on the phone and texted a picture of a contract to deliver the flax in November, adding "please confirm flax contract." Achter texted back a thumbs-up emoji. But when November came around, the flax was not delivered and prices for the crop had increased.

Mickleborough said the emoji amounted to an agreement because he had texted numerous contracts to Achter, who previously confirmed through text message and always fulfilled the order. But the farmer argued that the emoji indicated only that he'd received the contract in the text message. "I deny that he accepted the thumbs-up emoji as a digital signature of the incomplete contract," Achter said in an affidavit to court. "I did not have time to review the Flax Contract and merely wanted to indicate that I did receive his text message."

Justice Timothy Keene said in his June decision that the thumbs-up emoji did meet signature requirements and therefore the farmer breached his contract. The judge pointed to a Dictionary.com definition of the thumbs-up emoji, which said it is used to express assent, approval or encouragement in digital communications. "This court readily acknowledges that a (thumbs-up) emoji is a non-traditional means to `sign' a document but nevertheless under these circumstances this was a valid way to convey the two purposes of a `signature,"' Keene wrote in his decision. Keene's decision noted the case is novel, but the judge said emojis are now commonly used.

Bruce Power, a Canadian utility company, is planning to build the world's biggest nuclear plant as growing demand for clean energy spurs interest in atomic energy. The Financial Post reports: The Ontario government said Wednesday Bruce Power will conduct an environmental assessment of adding as much as 4.8 gigawatts of capacity to its plant in Canada's most-populous province. The plant's eight reactors currently have about 6.2 gigawatts of capacity and supply 30 per cent of the province's power. The expansion would make the site larger than Japan's Kashiwazaki-Kariwa plant, the biggest in the world with seven reactors and more than eight gigawatts of capacity.

"The European Space Agency's Euclid space telescope launched at 11:12 a.m. ET Saturday," reports CNN, "aboard a SpaceX Falcon 9 rocket from Florida's Cape Canaveral Space Force Station.

CNN is calling it "a mission designed to unravel some of the greatest mysteries of the universe." The 1.2-meter-diameter (4-foot-diameter) telescope has set off on a monthlong journey to its orbital destination of the sun-Earth Lagrange point L2, which is nearly 1 million miles (1.6 million kilometers) away from Earth and also home to NASA's James Webb Space Telescope... After arriving at orbit, Euclid will spend two months testing and calibrating its instruments — a visible light camera and a near-infrared camera/spectrometer — before surveying one-third of the sky for the next six years. Euclid's primary goal is to observe the "dark side" of the universe, including dark matter and dark energy. While dark matter has never actually been detected, it is believed to make up 85% of the total matter in the universe. Meanwhile, dark energy is a mysterious force thought to play a role in the accelerating expansion of the universe.

In the 1920s, astronomers Georges Lemaître and Edwin Hubble discovered that the universe has been expanding since its birth 13.8 billion years ago. But research that began in the 1990s has shown that something sparked an acceleration of the universe's expansion about 6 billion years ago, and the cause remains a mystery. Unlocking the true nature of dark energy and dark matter could help astronomers understand what the universe is made of, how its expansion has changed over time, and if there is more to understanding gravity than meets the eye... Euclid is designed to create the largest and most accurate three-dimensional map of the universe, observing billions of galaxies that stretch 10 billion light-years away to reveal how matter may have been stretched and pulled apart by dark energy over time. These observations will effectively allow Euclid to see how the universe has evolved over the past 10 billion years...

The telescope's image quality will be four times sharper than those of ground-based sky surveys. Euclid's wide perspective can also record data from a part of the sky 100 times bigger than what Webb's camera can capture. During its observations, the telescope will create a catalog of 1.5 billion galaxies and the stars within them, creating a treasure trove of data for astronomers that includes each galaxy's shape, mass and number of stars created per year. Euclid's ability to see in near-infrared light could also reveal previously unseen objects in our own Milky Way galaxy, such as brown dwarfs and ultra-cool stars.

In May 2027, Euclid will be joined in orbit by the Nancy Grace Roman Telescope. The two missions will overlap in their study of cosmic acceleration as they both create three-dimensional maps of the universe...Roman will study one-twentieth of the sky in infrared light, allowing for much more depth and precision. The Roman telescope will peer back to when the universe was just 2 billion years old, picking out fainter galaxies than Euclid can see.
CNN points out that "While primarily an ESA mission, the telescope includes contributions from NASA and more than 2,000 scientists across 13 European countries, the United States, Canada and Japan."

And they also note this statement from Jason Rhodes, a senior research scientist at NASA's Jet Propulsion Laboratory. "With these upcoming telescopes, we will measure dark energy in different ways and with far more precision than previously achievable, opening up a new era of exploration into this mystery."

From NASA's announcement: Scientists are unsure whether the universe's accelerated expansion is caused by an additional energy component, or whether it signals that our understanding of gravity needs to be changed in some way. Astronomers will use Roman and Euclid to test both theories at the same time, and scientists expect both missions to uncover important information about the underlying workings of the universe...

Less concentrated mass, like clumps of dark matter, can create more subtle effects. By studying these smaller distortions, Roman and Euclid will each create a 3D dark matter map... Tallying up the universe's dark matter across cosmic time will help scientists better understand the push-and-pull feeding into cosmic acceleration.
SpaceX tweeted footage of the telescope's takeoff, and the successful landing of their Falcon 9's first stage on a droneship called A Shortfall of Gravitas.

An anonymous reader quotes a report from The Guardian: Something fishy is happening in the Netherlands and viewers worldwide are hooked. No, this isn't the latest voyeuristic reality series from the creators of Big Brother and The Traitors. It's a charmingly innocent live stream which lets you ring a doorbell on behalf of some frisky fish. For the past three migration seasons, an online feed has broadcast live footage from an underwater camera at a lock to the west of Utrecht. Every spring, thousands of fish swish through the Netherlands' fourth-largest city, seeking shallow waters in which to lay their eggs. Some swim all the way to Germany, like piscine Adam Peatys. Slight snag: they often have to wait at the Weerdsluis lock, which seldom opens at this time of year.

Local ecologists came up with an ingenious solution: the world's first fish doorbell or visdeurbel in Dutch (try saying it out loud). If webcam watchers spot fish waiting to pass, they simply press a virtual doorbell and the lock keeper -- who can't see down into the water, which is 2.1 metres (7ft) deep, from dry land -- is sent a notification. When enough fish have gathered, the operator opens the 200-year-old sluice gate by hand to let them through. It enables professionals and the public to work together around the clock, ensuring fish don't have to wait too long. Like a marine midwife or damp doula, you can help them reach their spawning sites unscathed. It means they're less likely to fall victim to predators such as herons, cormorants and grebes (boo! baddies!).

The project is a collaboration between water authorities and the municipality of Utrecht as fish are a vital part of the ecosystem, eating insects and maintaining the cleanliness of canals. It also provides data about the plentiful wildlife beneath the serene surface of the city's waterways. No wonder visitors are logging on to lend a hand, waving through 2,000 fish a week. Politely holding a door open for our scaly pals -- who lack the opposable fins to do it themselves -- is a feelgood act of kindness. The green-tinged live feed is like a calming version of that giant puddle in Newcastle or an eco equivalent of Big Jet TV. It's wholesome, interactive and addictive, akin to a soggy Springwatch or a low-budget Blue Planet. "In spring 2021, the doorbell was rung more than 100,000 times by punters as far afield as Canada and Taiwan," notes the report. "Thanks to its growing fanbase, this has been its best year yet, hitting one million unique users and 8.2 million visits in total."

Google said Thursday it will remove Canadian news content from its search, news and discover products after a new law meant to compensate media outlets comes into force. CBC.ca reports: "We're disappointed it has come to this. We don't take this decision or its impacts lightly and believe it's important to be transparent with Canadian publishers and our users as early as possible," said Kent Walker, the president of global affairs at Google and Alphabet. "The unprecedented decision to put a price on links (a so-called 'link tax') creates uncertainty for our products and exposes us to uncapped financial liability simply for facilitating Canadians' access to news from Canadian publishers."

Prime Minister Justin Trudeau said the government was confident Google would come around on the legislation. "I will say the conversations with Google are ongoing. It is important that we find a way to ensure that Canadians can continue to access content in all sorts of ways but also that we protect rigorous independent journalism that has a foundational role in our democracies," he said. "We know that democracies only work with a strong independent diverse media and we will continue to work for that."

The bill has been pitched as a way to keep news outlets solvent after advertising moved en masse to digital platforms, virtually wiping out a major revenue stream for journalism. [...] In an attempt to reverse the revenue decline, the government's new regulatory regime will require companies like Google and the Meta-owned Facebook -- and other major online platforms that reproduce or facilitate access to news content -- to either pay to post content or go through a binding arbitration process led by an arms-length regulator, the Canadian Radio-television and Telecommunications Commission (CRTC). An outlet will be considered an eligible news business if it regularly employs two or more journalists in Canada, operates largely within Canada and produces content that is edited and designed in this country. Google and Meta have signaled they'd rather get out of the news-posting business altogether rather than deal with this process. Meta also announced last week that would be removing all news content from Facebook and Instagram for users in Canada. You can read more about the Online News Act here.

A collection of over 2,200 new old stock computers from the 1980s, manufactured by a company called NABU and featuring a groundbreaking pre-internet network, are being liberated from a barn in Massachusetts. "In a way, this is two stories: The first, of a breakthrough network from Canada, a consumer-friendly 1983 version of the internet decades ahead of its time," writes Ernie Smith via Motherboard. "The other story, of the man who got a hold of these machines, held onto them for 33 years, and mysteriously allowed them to flood the used market one day. One day, thanks to a confluence of the right people noticing the right eBay listings, these two stories merged and created a third story -- the tale of a computer network, brought back to life." An anonymous Slashdot reader shares an excerpt from the report: For more than two decades, the biggest retro computing story in recent memory sat like a sleeper cell in a Massachusetts barn. The barn was in danger of collapse. It could no longer protect the fleet of identical devices hiding inside. A story like this doesn't need the flash of a keynote or a high-profile marketing campaign. It really just needs someone to notice. And the reason anyone did notice was because this barn could no longer support the roughly 2,200 machines that hid on its second floor. These computers, with a weight equivalent to roughly 11 full-size vehicles, were basically new, other than the fact that they had sat unopened and unused for nearly four decades, roughly half that time inside this barn. Every box was "new old stock," essentially a manufactured time capsule, waiting to be found by somebody.

These machines, featuring the label of a forgotten brand built around an idea that was tragically too early to succeed, could have disappeared, anonymously, into the junkyard of history, as so many others like them have. Instead, they ended up on eBay, at a bargain-basement price of $59.99 each. And when the modern retro computing community turned them on, what they found was something worth bringing back to life. It took a while for anyone to notice these stylish metal-and-plastic machines from 1983. First, information spread like whispers in the community of tech forums, Discord servers, and Patreon channels where retro tech collectors hid. But then, a well-known tech YouTuber, Adrian Black, did a video about them, and these eBay machines, slapped with the logo of a company called NABU, were anonymous no more. [...]

Black was impressed. These devices, which utilized the landmark Z80 processor -- a chip common in embedded systems, arcade machines like Pac-Man, and home consoles like the Colecovision -- had an architecture very similar to the widely used MSX platform, making them a great choice for device hackers. (Well, minus the fact that they didn't have floppy drives.) Plus, they were essentially new. "It's new old stock, but it is tested," he says at the beginning of the clip. "I think the seller actually peeled the original tape off, tested it, and then taped it back up again." Essentially, this was the retro-computing version of a unicorn: An extremely obscure platform, being sold at a scale wide enough that basically anyone who wanted one could have it. And on top of all that, NABU -- an acronym standing for Natural Access to Bi-directional Utilities -- was essentially the 1983 version of AOL, except built around proprietary hardware. The flood of interest was so significant that it knocked the seller's eBay account offline for months while the company verified that the units were actually his. (They were.)

For people who love tinkering with devices, there was a lot to work with here, especially in 2023. There was a real chance that this relic of the past could live again, with its network available to anyone who took a chance on buying one of these devices. "The kind of hardware and software hacking that people are doing with those wouldn't have been possible 10 or even 5 years ago," says Sean Malseed, host of the popular YouTube channel Action Retro and one of the many people who bought a NABU from the mysterious eBay listing. "These machines were once considered basically e-waste, but instead they're seeing a very unlikely renaissance." So where did this computer come from? Why did this seller have so many? And why didn't you know about the NABU until now? [...]

Canada has launched a bid to attract techies working in the USA on the notorious H-1B visa, by offering them the chance to move north. From a report: The offer, announced on Wednesday as part of the nation's first ever tech talent strategy, means H-1B visa holders can move to Canada without having a job waiting for them. The H-1B visa is contentious in the USA. Its purpose is to attract skilled people whose talents are in short supply stateside, thus adding flexibility to the economy, but the visa is believed to be widely abused -- by employers who use it to find employees willing to work for less than their American peers.

But the visa is very popular in India -- one of the main sources of H-1B applicants. Indeed it's so popular that the Biden Administration last week announced moderate reforms to the program during the state visit by Indian prime minster Narendra Modi. The H-1B also made news early in 2023 amid mass layoffs in the tech sector, because visa holders who don't have jobs have just 90 days to leave the Land of the Free. Canada has clearly spotted an opportunity to nab some talent that needs a bolt-hole -- and can get that talent safe in the knowledge that its southern neighbor has vetted H-1B holders, and they already have some experience of working in North America.

Volve has joined Ford, General Motors, and Rivian in adopting Tesla's proprietary charging port. Car and Driver reports: Volvo says that starting in 2025 all of its electric vehicles will be equipped with a North American Charging Standard (NACS) port. This will allow them to charge at Tesla's far-reaching Supercharger network in Canada, Mexico, and the United States. The charging network is currently said to consist of 12,000-plus fast-chargers and is expected to continue to keep growing. "One major inhibitor to more people making the shift to electric driving, a key step in making transportation more sustainable, is access to easy and convenient charging infrastructure," Volvo CEO Jim Rowan said in a press release.

What does this mean for the owners of Volvo models built before the NACS adoption? The company says its current lineup of EVs, which includes the XC40 Recharge, the C40 Recharge, the recently revealed EX30, and the new three-row EX90 SUV that are are currently equipped with CCS-type charge ports, will be able to use an adapter to connect to Tesla's chargers. Volvo says the CCS-to-NACS adapter will be made available in the first half of next year, but what remains to be seen is how much it will cost, if anything. Also worth noting is that the automaker plans to offer a NACS-to-CCS adapter for future 2025 models for owners who wish to replenish their battery using that style charger.

Warnings over the safety of OceanGate's Titan submersible were repeatedly dismissed by the CEO of the company, email exchanges with a leading deep sea exploration specialist show. From a report: In messages seen by the BBC, Rob McCallum told OceanGate CEO Stockton Rush that he was potentially putting his clients at risk and urged him to stop using the sub until it had been classified by an independent body. Mr Rush responded that he was "tired of industry players who try to use a safety argument to stop innovation". The tense exchange ended after OceanGate's lawyers threatened legal action, Mr McCallum said. "I think you are potentially placing yourself and your clients in a dangerous dynamic," he wrote to the OceanGate boss in March 2018. "In your race to Titanic you are mirroring that famous catch cry: 'She is unsinkable'".

In the messages, Mr Rush, who was among five passengers who died when the Titan experienced what officials believe was a "catastrophic implosion" on Sunday, expresses frustration with the criticism of Titan's safety measures. "We have heard the baseless cries of 'you are going to kill someone' way too often," he wrote. "I take this as a serious personal insult." Mr McCallum told the BBC that he repeatedly urged the company to seek certification for the Titan before using it for commercial tours. The vessel was never certified or classed. "Until a sub is classed, tested and proven it should not be used for commercial deep dive operations," he wrote in one email. "I implore you to take every care in your testing and sea trials and to be very, very conservative," he added. "As much as I appreciate entrepreneurship and innovation, you are potentially putting an entire industry at risk." In his response a few days later, Mr Rush defended his business and his credentials. He said OceanGate's "engineering focused, innovative approach... flies in the face of the submersible orthodoxy, but that is the nature of innovation".

Meta plans to end access to news on Facebook and Instagram for all users in Canada once a parliament-approved legislation requiring internet giants to pay news publishers comes into effect, the company said on Thursday. From a report: The legislation, known as the Online News Act, was approved by the Senate upper chamber earlier on Thursday and will become law after receiving royal assent from the governor general, a formality. The legislation was proposed after complaints from Canada's media industry, which wants tighter regulation of tech companies to prevent them from elbowing news businesses out of the online advertising market.

"Today, we are confirming that news availability will be ended on Facebook and Instagram for all users in Canada prior to the Online News Act taking effect," Meta said in a statement. Facebook had telegraphed such a move for weeks, saying news has no economic value to the company and that its users do not use the platform for news. The act outlines rules to force platforms such as Facebook and Alphabet's Google to negotiate commercial deals and pay news publishers for their content, a step similar to a groundbreaking law passed in Australia in 2021.

An anonymous reader quotes a report from KrebsOnSecurity: The United Parcel Service (UPS) says fraudsters have been harvesting phone numbers and other information from its online shipment tracking tool in Canada to send highly targeted SMS phishing (a.k.a. "smishing") messages that spoofed UPS and other top brands. The missives addressed recipients by name, included details about recent orders, and warned that those orders wouldn't be shipped unless the customer paid an added delivery fee. In a snail mail letter sent this month to Canadian customers, UPS Canada Ltd. said it is aware that some package recipients have received fraudulent text messages demanding payment before a package can be delivered, and that it has been working with partners in its delivery chain to try to understand how the fraud was occurring.

"During that review, UPS discovered a method by which a person who searched for a particular package or misused a package look-up tool could obtain more information about the delivery, potentially including a recipient's phone number," the letter reads. "Because this information could be misused by third parties, including potentially in a smishing scheme, UPS has taken steps to limit access to that information." The written notice goes on to say UPS believes the data exposure "affected packages for a small group of shippers and some of their customers from February 1, 2022 to April 24, 2023." [...]

In a statement provided to KrebsOnSecurity, Sandy Springs, Ga. based UPS [NYSE:UPS] said the company has been working with partners in the delivery chain to understand how that fraud was being perpetrated, as well as with law enforcement and third-party experts to identify the cause of this scheme and to put a stop to it. "Law enforcement has indicated that there has been an increase in smishing impacting a number of shippers and many different industries," reads an email from Brian Hughes, director of financial and strategy communications at UPS. "Out of an abundance of caution, UPS is sending privacy incident notification letters to individuals in Canada whose information may have been impacted," Hughes said. "We encourage our customers and general consumers to learn about the ways they can stay protected against attempts like this by visiting the UPS Fight Fraud website."

Meta has confirmed that it will remove all news content from Facebook and Instagram for users in Canada, following the passing of the Online News Act by the Canadian Parliament. Engadget reports: "Today, we are confirming that news availability will be ended on Facebook and Instagram for all users in Canada prior to the Online News Act (Bill C-18) taking effect," the company posted. "We have repeatedly shared that in order to comply with Bill C-18, passed today in Parliament, content from news outlets, including news publishers and broadcasters, will no longer be available to people accessing our platforms in Canada."

The Online News Act is designed to address the precipitous drop in advertising revenue Canadian news organizations have experienced over the past two decades. It does so by requiring big tech companies like Google and Meta to negotiate reimbursement plans with those outlets for running said stories on their respective platforms. Earlier in June, Meta announced that it was working to develop a software-based solution to its C-18 issue. As of Thursday, those efforts remain ongoing "and currently impact a small percentage of users in Canada." Aside from the loss of news functionality, Meta assures its users that no other aspects of the Facebook experience will be impacted.

Canada is set for massive growth in wind power generation as it moves toward net zero emissions by 2050, a new report by the country's energy regulator suggested. From a report: The report models how energy consumption is expected to change under various scenarios as the world reduces its carbon emissions, and it projects electricity use will more than double in Canada from now until mid-century. "Among all technologies, wind contributes the greatest amount of new generation by 2050, increasing ninefold from current levels," the Canada Energy Regulator said, using a scenario it calls "global net zero" that assumes the world acts quickly enough to limit global warming to 1.5 degrees Celsius by 2050.

The regulator's model sees the greatest amount of new wind power being built in the provinces of Alberta, Saskatchewan, British Columbia and Ontario. Natural Resources Minister Jonathan Wilkinson said he wasn't surprised to see the emphasis on wind generation, given how much it's come down in cost. Building it out quickly will be a challenge, he acknowledged, but he sees it as achievable -- despite the controversy that large-scale wind projects often prompt in neighboring communities.

"Some of this will also come from offshore wind, which perhaps in terms of public acceptance is easier, because it's a long way offshore," he said by phone Tuesday. "Those are often very large facilities, and Canada has been a little bit slower on the offshore than our European counterparts." Solar power will grow at a much slower pace than wind power, the report projects, eventually making up 5 per cent of generation by 2050.

Microsoft is increasing its Xbox Series X prices in most countries in August apart from the US, Japan, Chile, Brazil, and Colombia. From a report: The Xbox maker is also increasing the monthly prices of its Xbox Game Pass and Xbox Game Pass Ultimate subscriptions for the first time next month, which will see the base Game Pass subscription for console move up to $10.99 a month from $9.99. "We've held on our prices for consoles for many years and have adjusted the prices to reflect the competitive conditions in each market," says Kari Perez, head of communications for Xbox, in a statement to The Verge. Xbox Series X console pricing will largely match the price hike Sony announced for the PS5 last year, with the Xbox Series X moving to $612 in the UK, $604 across most European markets, CAD $649.99 in Canada, and AUD $799.99 in Australia starting August 1st. The Xbox Series S pricing will not be adjusted in any markets, remaining at $299.99.

A submersible craft used to take people to see the wreck of the Titanic has gone missing in the Atlantic Ocean with its crew on board, sparking a major search and rescue operation. From a report: Tour firm OceanGate, which runs $250,000-a-seat expeditions to the wreck, said it was exploring all options to get the crew back safely. It said government agencies and deep sea firms were helping the operation. The Titanic sank in 1912 and lies some 3,800m (12,500ft) beneath the waves. The missing craft is believed to be OceanGate's Titan submersible, a truck-sized sub that holds five people and usually dives with a four-day supply of oxygen. It is not known when contact with the craft was lost.

"Our entire focus is on the crewmembers in the submersible and their families," OceanGate said in a statement. "We are deeply thankful for the extensive assistance we have received from several government agencies and deep sea companies in our efforts to re-establish contact with the submersible," it added. The company bills the eight-day trip on its carbon-fibre submersible as a "chance to step outside of everyday life and discover something truly extraordinary." According to its website, one expedition is ongoing and two more have been planned for June 2024.

An anonymous reader shared this report from the Washington Post: An outbreak of severe storms, including deadly tornadoes, hail bigger than DVDs and life-threatening flooding, has ravaged the South, coming amid a month of wild weather across North America. Texas is baking beneath heat indexes as high as 120 degrees, the coasts are cool and mostly calm and Canadian wildfire smoke is suffocating much of the northern U.S.

If it seems the weather has been a little bit "off" since the calendar flipped to June, you're not imagining it — things have been downright weird. It's all linked to a bizarre jet stream pattern, which is displacing air masses from their typical positions and disrupting the movement of weather systems across the continent.
Among other things, the jet stream created a sprawling heat dome in Canada which "helped sap the landscape of moisture, leaving it ripe to burn," the article points out.

"Meanwhile in the southern U.S., the roaring southern branch of the jet stream has been energizing storms. That's brewed back-to-back rounds of severe weather, complete with strong winds, tornadoes and 'gargantuan' hail — and the pattern doesn't look to budge soon." [El Niño] historically, has been linked to split-flow jet stream patterns like the one driving wild weather across parts of the Lower 48. Natural variability, a.k.a. randomness, is also a big player, but it stands to reason that the two factors, overlapping together, are in large part culpable for what we've been facing.

Some scientific research also suggests human-caused climate change may increase the chances of slow, wonky jet stream patterns such as the one being observed this summer. The idea is that the disproportionate warming of the high latitudes is reducing the temperature contrast between the north and south, weakening the jet stream and thus causing it to take bigger dips and meander more. It remains a controversial idea.

An anonymous reader quotes a report from Phys.Org: In a world of worsening climate extremes, a single red line has caught many people's attention. The line, which charts sea surface temperatures in the North Atlantic Ocean, went viral over the weekend for its startling display of unprecedented warming -- nearly 2 degrees (1.09 Celsius) above the mean dating back to 1982, the earliest year with comparable data. Ocean temperatures are so anomalously high that Eliot Jacobson, a retired mathematics professor who created the graph using data from the National Oceanic and Atmospheric Administration, had to "increase the upper bound on the y-axis," he said. "I've been doing this for a long time, but this one was like, 'Oh my God, look at this,'" Jacobson said of the graph. "What is going on here?" He and other researchers said there are several factors that may be contributing to the off-the-charts warming, which is occurring alongside other climate woes including record-shattering wildfires in Canada, rapidly declining sea ice in Antarctica and unusually warm temperatures in many parts of the world, not including Southern California.

Underlying everything is human-caused climate change, said Daniel Swain, a climate scientist at UCLA. But atop that are a handful of other potential factors, including the early arrival of El Nino; the recent eruption of the Hunga Tonga volcano; new regulations around sulfur aerosol emissions or even a dearth of Saharan dust. "The North Atlantic is record-shatteringly warm right now," Swain said during a briefing Monday. "There has never been any day in observed history where the entire North Atlantic has been nearly as warm as it is right now, at any time of year." Nearly all of the Atlantic basin is experiencing anomalous warmth, including the Irminger Sea southeast of Greenland, the western Mediterranean Sea, and the tropics "all the way from Africa to at least the Caribbean," said Gregory Johnson, an oceanographer at NOAA's Pacific Marine Environmental Laboratory. "We are definitely in record territory," Johnson said. And it's not just the Atlantic, as global sea surface temperatures are also climbing to new highs, NOAA data show. "The primary cause of the warming we are seeing right now is an El Nino event on top of overall human-caused warming," Mann said.

Though concerning, the conditions aren't "completely out of left field" based on global warming trends, Swain said. "The long-term trend is not going to stop, and we are stair-stepping up our way to much warmer oceans and a much warmer climate, and there still hasn't been a great deal of momentum away from that," he said. "We're still moving in a pretty alarming direction, overall, when it comes to to warming."

schwit1 shares a report from VentureBeat: [A]s those following the burgeoning industry and its underlying research know, the data used to train the large language models (LLMs) and other transformer models underpinning products such as ChatGPT, Stable Diffusion and Midjourney comes initially from human sources -- books, articles, photographs and so on -- that were created without the help of artificial intelligence. Now, as more people use AI to produce and publish content, an obvious question arises: What happens as AI-generated content proliferates around the internet, and AI models begin to train on it, instead of on primarily human-generated content?

A group of researchers from the UK and Canada have looked into this very problem and recently published a paper on their work in the open access journal arXiv. What they found is worrisome for current generative AI technology and its future: "We find that use of model-generated content in training causes irreversible defects in the resulting models." Specifically looking at probability distributions for text-to-text and image-to-image AI generative models, the researchers concluded that "learning from data produced by other models causes model collapse -- a degenerative process whereby, over time, models forget the true underlying data distribution ... this process is inevitable, even for cases with almost ideal conditions for long-term learning."

"Over time, mistakes in generated data compound and ultimately force models that learn from generated data to misperceive reality even further," wrote one of the paper's leading authors, Ilia Shumailov, in an email to VentureBeat. "We were surprised to observe how quickly model collapse happens: Models can rapidly forget most of the original data from which they initially learned." In other words: as an AI training model is exposed to more AI-generated data, it performs worse over time, producing more errors in the responses and content it generates, and producing far less non-erroneous variety in its responses. As another of the paper's authors, Ross Anderson, professor of security engineering at Cambridge University and the University of Edinburgh, wrote in a blog post discussing the paper: "Just as we've strewn the oceans with plastic trash and filled the atmosphere with carbon dioxide, so we're about to fill the Internet with blah. This will make it harder to train newer models by scraping the web, giving an advantage to firms which already did that, or which control access to human interfaces at scale.

The extent of area burned in California's summer wildfires increased about fivefold from 1971 to 2021, and climate change was a major reason why, according to a new analysis. Scientists estimate the area burned in an average summer may jump as much as 50% by 2050. From a report: Days after wildfire smoke from Canada turned skies orange along the US Eastern Seaboard, the study is further confirmation of past research showing that higher temperatures and drier conditions in many parts of the world make wildfires more likely. Wildfires worsened by greenhouse gases emitted by human activities tore through Australia in 2019 and 2020 and Siberia in 2020. The peer-reviewed research, published Monday in the Proceedings of the National Academy of Sciences, finds that wildfires in California's northern and central forests scorch the most area when temperatures are high and less area when it's cooler.

Marco Turco, a climate researcher at the University of Murcia in Spain, and colleagues designed the study to try to identify how much of the increase in the burned area of California fires was due to climate change, and how much to natural variability. They conducted a statistical analysis of temperature and forest-fire data for California summers in the period 1971 to 2021. They then drew on modeling that shows how the last several decades might have evolved without human-caused greenhouse gas emissions. The result: Burned area grew 172% more than it would have without climate change. Manmade effects began to overwhelm what would be expected without greenhouse gas pollution after 2001, the researchers concluded.

New research suggests that Arctic summer sea ice could melt almost completely by the 2030s, a decade earlier than previously projected, even with significant greenhouse gas emissions reductions. Smithsonian Magazine reports: "We are very quickly about to lose the Arctic summer sea-ice cover, basically independent of what we are doing," Dirk Notz, a climate scientist at the University of Hamburg in Germany tells the New York Times' Raymond Zhong. "We've been waiting too long now to do something about climate change to still protect the remaining ice." An ice-free summer, also called a "blue ocean event," will happen when the sea ice drops below one million square kilometers (386,102 square miles), writes Jonathan Bamber, a professor of physical geography at the University of Bristol, in the Conversation. This equates to just 15 percent of the Arctic's seasonal minimum ice cover of the late 1970s, per the Times.

Previous assessments using models have estimated an ice-free summer under high and intermediate emissions scenarios by 2050. But researchers noticed differences between what climate models predicted about what would happen to sea ice and what they've actually seen through observations, according to Bob Weber of the Canadian Press. "The models, on average, underestimate sea ice decline compared with observations," says Nathan Gillett, an environment and climate change Canada scientist, to Weber.

Now, in a new study published in Nature Communications, Notz, Gillett and their colleagues tweaked these models to more closely fit satellite data collected over the past 40 years. Using these modified models, the researchers projected ice changes under different possible levels of greenhouse gas emissions. Their paper suggests that regardless of emissions scenario, "we may experience an unprecedented ice-free Arctic climate in the next decade or two." Under a high emissions scenario, the Arctic could see a sustained loss of sea ice from August until as late as October before the 2080s, lead author Seung-Ki Min, a climate scientist at Pohang University of Science and Technology in South Korea, tells CNN's Rachel Ramirez.
