FBI Warns Chinese Malware Could Threaten Critical US Infrastructure (ft.com) 78

The FBI is "laser focused" on Chinese efforts to insert malicious software code into computer networks in ways that could disrupt critical US infrastructure, according to the agency's director Christopher Wray. From a report: Wray said he was acutely concerned about "pre-positioning" of malware. He said the US recently disrupted a Chinese hacking network known as Volt Typhoon that targeted American infrastructure including the electricity grid and water supply, and other targets around the world. "We're laser focused on this as a real threat and we're working with a lot of partners to try to identify it, anticipate it and disrupt it," Wray said on Sunday after attending the Munich Security Conference.

"I'm sober and clear minded about what we're up against...We're always going to have to be kind of on the balls of our feet." Wray said Volt Typhoon was just the tip of the iceberg and was one of many such efforts by the Chinese government. The US has been tracking Chinese pre-positioning operations for well over a decade, but Wray told the security conference that they had reached "fever pitch." He said China was increasingly inserting "offensive weapons within our critical infrastructure poised to attack whenever Beijing decides the time is right."

His comments are the latest FBI effort to raise awareness about Chinese espionage that ranges from traditional spying and intellectual property theft to hacking designed to prepare for possible future conflict. Last October, Wray and his counterparts from the Five Eyes intelligence-sharing network that includes the US, UK, Canada, Australia and New Zealand held their first public meeting in an effort to focus the spotlight on Chinese espionage. Wray said the US campaign was having an impact and that people were increasingly attuned to the threat, particularly compared with several years ago when he sometimes met scepticism.

Could Solar Water Heaters Become Popular Again? (msn.com) 123

An article in the Washington Post remembers a 1980s-era "glass box with metal water pipes running through it" that "converted sunlight into hot water. By trapping solar energy like a greenhouse, it heated the water to a scorching 180 degrees Fahrenheit.

"[T]oday, hardly anyone is using these solar water heaters even as photovoltaic panels have popped up on the roofs of nearly 4 million American homes." Unlike photovoltaic panels, which can power your home, solar thermal panels are mainly used to heat water. But they're smaller and more efficient. The technology converts 60 to 70 percent of the sun's energy into heat. Even the best photovoltaics, which generate electricity, only achieve 24 percent efficiency. Now, a new generation of solar water heater manufacturers is hoping subsidies under the Inflation Reduction Act, and growing interest in net-zero emissions, will reignite their growth.

Theoretically, solar thermal offers a big opportunity to slash emissions. Nearly 20 percent of an average home's energy is used to heat water, and nearly 50 percent globally, according to MIT. By adopting solar water heaters, the average household can keep 2 tons of carbon dioxide out of the atmosphere, the equivalent of not driving your car for four months, estimates the Environmental Protection Agency. Solar water heaters can also save money, cutting the average utility bill by $400 to $600 per year, the Energy Department estimates...

Only about 370,000 solar thermal systems were operating in the United States by the end of 2021, according to the International Energy Agency, many of them on larger commercial buildings...

Since they can cut fuel consumption to heat water by 50 percent to 70 percent, other countries are embracing the technology: Almost all new residential buildings in Israel must include solar thermal, while in countries as far north as Canada and Denmark, solar thermal energy warms millions of homes with district heating systems. Yet these systems represent a tiny fraction of the potential, supplying 0.4 percent of today's global energy demand for domestic hot water.

New U.S. subsidies can cut the price in half depending on location, the article points out.

Cheap photovoltaics still make economic sense for many homes (unless you're heating a pool). "But the cost of solar thermal could look like a bargain if we consider increasingly unreliable electric grids and the cost to the climate from burning fossil fuels."

OSIRIS-REx's Final Haul: 121.6 Grams From Asteroid Bennu (universetoday.com) 17

According to NASA, the OSIRIS-REx mission has successfully collected 121.6 grams, or almost 4.3 ounces, of rock and dust from the asteroid Bennu. Universe Today reports: These samples have been a long time coming. The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) was approved by NASA back in 2011 and launched in September 2016. It reached its target, the carbonaceous Apollo group asteroid 101955 Bennu, in December 2018. After spending months studying the asteroid and reconnoitring for a suitable sampling location, it selected one in December 2019. After two sampling rehearsals, the spacecraft gathered its sample on October 20th, 2020. In September 2023, the sample finally returned to Earth.

For OSIRIS-REx to be successful, it had to collect at least 60 grams of material. With a final total that is double that, it should open up more research opportunities and allow more of the material to be held untouched for future research. NASA says they will preserve 70% of the sample for the future, including for future generations. The next step is for the material to be put into containers and sent to researchers. More than 200 researchers around the world will receive samples. Many of the samples will find their way to scientists at NASA and institutions in the US, while others will go to researchers at institutions associated with the Canadian Space Agency, JAXA, and other partner nations. Canada will receive 4% of the sample, the first time that Canada's scientific community will have direct access to a returned asteroid sample.

Air Canada Found Liable For Chatbot's Bad Advice On Plane Tickets 72

An anonymous reader quotes a report from CBC.ca: Air Canada has been ordered to pay compensation to a grieving grandchild who claimed they were misled into purchasing full-price flight tickets by an ill-informed chatbot. In an argument that appeared to flabbergast a small claims adjudicator in British Columbia, the airline attempted to distance itself from its own chatbot's bad advice by claiming the online tool was "a separate legal entity that is responsible for its own actions."

"This is a remarkable submission," Civil Resolution Tribunal (CRT) member Christopher Rivers wrote. "While a chatbot has an interactive component, it is still just a part of Air Canada's website. It should be obvious to Air Canada that it is responsible for all the information on its website. It makes no difference whether the information comes from a static page or a chatbot." In a decision released this week, Rivers ordered Air Canada to pay Jake Moffatt $812 to cover the difference between the airline's bereavement rates and the $1,630.36 they paid for full-price tickets to and from Toronto bought after their grandmother died.

Every Country Needs Sovereign AI, Nvidia CEO Says (nvidia.com) 69

Nvidia blog: Every country needs to own the production of their own intelligence, NVIDIA founder and CEO Jensen Huang told attendees Monday at the World Governments Summit in Dubai. Huang, who spoke as part of a fireside chat with the UAE's Minister of AI, His Excellency Omar Al Olama, described sovereign AI -- which emphasizes a country's ownership over its data and the intelligence it produces -- as an enormous opportunity for the world's leaders. "It codifies your culture, your society's intelligence, your common sense, your history -- you own your own data," Huang told Al Olama during their conversation, a highlight of an event attended by more than 4,000 delegates from 150 countries.

"We completely subscribe to that vision," Al Olama said. "That's why the UAE is moving aggressively on creating large language models and mobilizing compute." Huang's appearance in the UAE comes as the Gulf State is moving rapidly to transform itself from an energy powerhouse into a global information technology hub. Dubai is the latest stop for Huang in a global tour that has included meetings with leaders in Canada, France, India, Japan, Malaysia, Singapore and Vietnam over the past six months. The Middle East is poised to reap significant benefits from AI, with PwC projecting a $320 billion boost to the region's economy by 2030.

Canada Moves To Ban the Flipper Zero Over Car Hacking Fears 63

It appears that the government of Canada is going to ban the Flipper Zero, the tiny, modular hacking device that's become popular with techies for its deviant digital powers. From a report: On Thursday, following a summit that focused on "the growing challenge of auto theft in Canada," the country's Minister of Innovation, Science and Industry posted a statement on X, saying "Criminals have been using sophisticated tools to steal cars...Today, I announced we are banning the importation, sale and use of consumer hacking devices, like flippers, used to commit these crimes.

In a press release issued on Thursday, the Canadian government confirmed that it will be pursuing "all avenues to ban devices used to steal vehicles by copying the wireless signals for remote keyless entry, such as the Flipper Zero." The Flipper, which is technically a penetration testing device, has been controversial due to its ability to hack droves of smart products. Alex Kulagin, the COO of Flipper Devices, said in a statement shared with Gizmodo that the device couldn't be used to "hijack any car" and that certain circumstances would have to be met for it to happen:

Chinese Hackers Embedded in US Networks For at Least Five Years (bloomberg.com) 15

The Chinese state-sponsored hacking group known as Volt Typhoon has been living in the networks of some critical industries for "at least five years," (non-paywalled link) according to a joint cybersecurity advisory issued by the US and its allies on Wednesday. From a report: The compromised environments are in the continental US and elsewhere, including Guam, the advisory said. It was published by US agencies and their security counterparts in Australia, Canada, the UK and New Zealand. The report comes a week after US officials announced an operation to disrupt Volt Typhoon by deleting malware from thousands of internet-connected devices the group had hijacked to gain access to the networks in critical parts of the economy. Among the sectors targeted were communications, energy, transportation and water systems.

Crypto Mining Company Loses Bid To Force Canadian Utility Company To Provide Power (vancouversun.com) 88

An anonymous reader quotes a report from Vancouver Sun: A cryptocurrency firm has lost a bid to force B.C. Hydro to provide the vast amounts of power needed for its operations, in a court ruling that upholds the provincial government's right to pause power connections for new crypto miners. Conifex Timber Inc., a forestry firm that branched out into cryptocurrency "mining," had gone to the B.C. Supreme Court to have the policy declared invalid. But Justice Michael Tammen ruled Friday that the government's move in December 2022 to pause new connections for cryptocurrency mining for 18 months was reasonable and not unduly discriminatory.

B.C. Hydro CEO Christopher O'Riley had told the court in an affidavit that the data centers proposed by Conifex would have consumed 2.5 million megawatt-hours of electricity a year. That's enough to power and heat more than 570,000 apartments, according to data on the power provider's website. Energy Minister Josie Osborne said when the policy was introduced that cryptocurrency mining consumes "massive amounts of electricity" by running banks of high-powered computers around the clock, but adds "very few jobs" to the local economy. In a statement released Monday, the company said it's "disappointed" with the court's ruling and is considering an appeal.
"Conifex continues to believe that the provincial government is missing out on several opportunities available to it to improve energy affordability, accelerate technological innovation, strengthen the reliability and resiliency of the power distribution grid in British Columbia, and achieve more inclusive economic growth," said Conifex in a statement.

152 Birds Named After People Will Be Renamed - But How? (slate.com) 258

An anonymous reader shared this report from Slate: Last November, the American Ornithological Society, or AOS, announced that it would change the common names of all American birds named after people. There are 152 such "eponymic" names (that is, birds that are named after a specific person, like Bicknell's Thrush) on the AOS' official checklist, and the group is planning to start with between 70 and 80 species predominantly found in the U.S. and Canada. In the coming years, birds like Cooper's Hawk, Wilson's Snipe, and Lincoln's Sparrow will be stripped of their eponyms and given new common English names.

The eponymic naming issue has been heating up in the bird world for a few years now. Birds got their English names when they were "discovered" by Western scientists, or otherwise identified as a new species. This meant ornithologists had the honor of coming up with whatever moniker they wanted, and frequently named birds in honor of a benefactor, a friend, or the person who shot the first known specimen. But a growing number of ornithologists and nonscientist birders are questioning why we're stuck with names decided on a whim hundreds of years ago, especially when the names aren't very good...

Rather than attempt the impossible task of reviewing the people with birds named after them one by one, the AOS said it would just scrap them all and start from scratch. But that's where the real challenge comes in — because lots of bird names are pretty bad. Not offensive bad, like named after a Confederate general, but just unsatisfactory bad. There was never any standardization for how common bird names were granted, which means those names are all over the place and provide little guidance for what renaming should look like.

Birds are named after their identifying features, size, habitat, the sound they make, or where they were first discovered. So the American Ornithological Society announced it will "conduct an open, inclusive, and scientifically rigorous pilot program in 2024 to develop its new approach to English bird names in the U.S. and Canada." [T]here are few specifics yet, and no easy way to organize the public and whittle down suggestions in the lawless and nonsensical world of bird names. But the AOS has committed to change: Unlike the closed-door decisions of the past, this will be a public process. The plan is to take suggestions — from field marks, Indigenous names, colloquialisms ... from anywhere — narrow it down, somehow, to a few options, and let people decide... Our new bird names won't be ideal — none of them are — but, for the first time, they will belong to us.

Inert Nuclear Missile Found in US Man's Garage (bbc.co.uk) 59

The BBC reports: Police in Washington state say an old rusted rocket found in a local man's garage is an inert nuclear missile. On Wednesday, a military museum in Ohio called police in the city of Bellevue to report an offer of a rather unusual donation. The police then sent a bomb squad to the potential donor's home... In a press release, police say the device is "in fact a Douglas AIR-2 Genie (previous designation MB-1), an unguided air-to-air rocket that is designed to carry a 1.5 kt W25 nuclear warhead". However, there was no warhead attached, meaning there was never any danger to the community. Bellevue Police Department spokesman Seth Tyler, told BBC News on Friday that the device was "just basically a gas tank for rocket fuel". He called the event "not serious at all... In fact, our bomb squad member asked me why we were releasing a news release on a rusted piece of metal," he said...

The man told police that the rocket belonged to a neighbour who had died, and was originally purchased from an estate sale.

Citing a Seattle Times article, the BBC notes that "The first and only live firing of the Genie rocket was in 1957, according to the newspaper, and production of it ended in 1962."

Police Departments Are Turning To AI To Sift Through Unreviewed Body-Cam Footage (propublica.org) 40

An anonymous reader quotes a report from ProPublica: Over the last decade, police departments across the U.S. have spent millions of dollars equipping their officers with body-worn cameras that record what happens as they go about their work. Everything from traffic stops to welfare checks to responses to active shooters is now documented on video. The cameras were pitched by national and local law enforcement authorities as a tool for building public trust between police and their communities in the wake of police killings of civilians like Michael Brown, an 18 year old black teenager killed in Ferguson, Missouri in 2014. Video has the potential not only to get to the truth when someone is injured or killed by police, but also to allow systematic reviews of officer behavior to prevent deaths by flagging troublesome officers for supervisors or helping identify real-world examples of effective and destructive behaviors to use for training. But a series of ProPublica stories has shown that a decade on, those promises of transparency and accountability have not been realized.

One challenge: The sheer amount of video captured using body-worn cameras means few agencies have the resources to fully examine it. Most of what is recorded is simply stored away, never seen by anyone. Axon, the nation's largest provider of police cameras and of cloud storage for the video they capture, has a database of footage that has grown from around 6 terabytes in 2016 to more than 100 petabytes today. That's enough to hold more than 5,000 years of high definition video, or 25 million copies of last year's blockbuster movie "Barbie." "In any community, body-worn camera footage is the largest source of data on police-community interactions. Almost nothing is done with it," said Jonathan Wender, a former police officer who heads Polis Solutions, one of a growing group of companies and researchers offering analytic tools powered by artificial intelligence to help tackle that data problem.

The Paterson, New Jersey, police department has made such an analytic tool a major part of its plan to overhaul its force. In March 2023, the state's attorney general took over the department after police shot and killed Najee Seabrooks, a community activist experiencing a mental health crisis who had called 911 for help. The killing sparked protests and calls for a federal investigation of the department. The attorney general appointed Isa Abbassi, formerly the New York Police Department's chief of strategic initiatives, to develop a plan for how to win back public trust. "Changes in Paterson are led through the use of technology," Abbassi said at a press conference announcing his reform plan in September, "Perhaps one of the most exciting technology announcements today is a real game changer when it comes to police accountability and professionalism." The department, Abassi said, had contracted with Truleo, a Chicago-based software company that examines audio from bodycam videos to identify problematic officers and patterns of behavior.

For around $50,000 a year, Truleo's software allows supervisors to select from a set of specific behaviors to flag, such as when officers interrupt civilians, use profanity, use force or mute their cameras. The flags are based on data Truleo has collected on which officer behaviors result in violent escalation. Among the conclusions from Truleo's research: Officers need to explain what they are doing. "There are certain officers who don't introduce themselves, they interrupt people, and they don't give explanations. They just do a lot of command, command, command, command, command," said Anthony Tassone, Truleo's co-founder. "That officer's headed down the wrong path." For Paterson police, Truleo allows the department to "review 100% of body worn camera footage to identify risky behaviors and increase professionalism," according to its strategic overhaul plan. The software, the department said in its plan, will detect events like uses of force, pursuits, frisks and non-compliance incidents and allow supervisors to screen for both "professional and unprofessional officer language."
There are around 30 police departments currently use Truleo, according to the company.

Christopher J. Schneider, a professor at Canada's Brandon University who studies the impact of emerging technology on social perceptions of police, is skeptical the AI tools will fix the problems in policing because the findings might be kept from the public just like many internal investigations. "Because it's confidential," he said, "the public are not going to know which officers are bad or have been disciplined or not been disciplined."

Starbucks is Launching Its Olive Oil-Infused Beverages Nationwide (cnn.com) 82

Starbucks is taking its extra virgin olive oil-infused drinks -- which some customers previously complained of sending them straight to the bathroom ï-- nationwide beginning Tuesday. CNN: The lineup, called Oleato, launched in a few US cities last year before slowly expanding to more stores. Tuesday's launch across its US and Canada locations signifies that the chain stands behind the beverage despite subpar reviews from customers and critics. On the Oleato menu are two drinks: An oat milk latte infused with the extra virgin olive oil; and a new toffeenut iced shaken espresso with golden foam, which is vanilla sweet cream infused with extra virgin olive oil into a cold foam. The drinks debuted in Italy in 2023, with a Starbucks executive previously telling CNN that it's one of its "biggest launches we've had in decades."

Companies Once Focused On Mining Cryptocurrency Pivot To Generative AI (theguardian.com) 48

"Companies that once serviced the boom in cryptocurrency mining are pivoting to take advantage of the latest data gold rush," reports the Guardian. Canadian company Hive Blockchain changed its name in July to Hive Digital Technologies and announced it was pivoting to AI. "Hive has been a pioneering force in the cryptocurrency mining sector since 2017. The adoption of a new name signals a significant strategic shift to harness the potential of GPU Cloud compute technology, a vital tool in the world of AI, machine learning and advanced data analysis, allowing us to expand our revenue channels with our Nvidia GPU fleet," the company said in its announcement at the time. The company's executive chairman, Frank Holmes, told Guardian Australia the transition required a lot of work. "Moving from mining Ethereum to hosting GPU cloud services involves buying powerful new servers for our GPUs, upgrading networking equipment and moving to higher tier data centres," he said.

"The only commonality is that GPUs are the workhorses in both cases. GPU cloud requires higher end supporting hardware and a more secure, faster data centre environment. There's a steep learning curve in the GPU cloud business, but our team is adapting well and learning fast."

For others, like Iris Energy, a datacentre company operating out of Canada and Texas, and co-founded by Australian Daniel Roberts, it has been the plan all along. Iris did not require any changes to the way the company operated when the AI boom came along, Roberts told Guardian Australia. "Our strategy really has been about bootstrapping the datacentre platform with bitcoin mining, and then just preserve optionality on the whole digital world. The distinction with us and crypto-miners is we're not really miners, we're datacentre people." The company still trumpets its bitcoin mining capability but in the most recent results Iris said it was well positioned for "power dense computing" with 100% renewable energy. Roberts said it wasn't an either-or situation between bitcoin mining and AI.

"I think when you look at bitcoin versus AI, the market will just reach equilibrium based on the market-based demands for each product," he said... Holmes said Hive also saw the two industries operating in parallel. "We love the bitcoin mining business, but its revenue is rather unpredictable. GPU cloud services should complement it well," he said.

Doomsday Clock Stays at 90 Seconds To Midnight (bbc.com) 61

Tony Isaac writes: The doomsday clock remains at 90 seconds to midnight, the same as last year. Interestingly, the Bulletin of the Atomic Scientists added 'AI' to the list of threats that they consider to be existential threats to humanity, but didn't move the hands of the clock as a result of adding that threat. My take is that they consider AI to be a very low-grade threat, but it makes me wonder why they included it at all.

Netflix is Going To Take Away Its Cheapest Ad-Free Plan (theverge.com) 105

Although Netflix no longer allows new or returning members to sign up for the ad-free Basic subscription that costs $11.99 per month, company executives told investors while reporting its earnings results today that it's retiring the plan in some countries where ad-supported plans are available. It's starting with Canada and the UK in the second quarter of this year. From a report: That leaves subscribers with Netflix's $15.49 per month option as Netflix's cheapest ad-free plan. Going from $11.99 to $15.49 per month is a pretty big jump, and means there's really no middle ground for ad-free plans. Otherwise, subscribers will have to pay $6.99 per month for its ad-supported basic plan or $22.99 per month for the Premium tier. Netflix stopped letting new subscribers sign up for its Basic plan in Canada last year before rolling out the change to the US and UK.

Netflix Buys Rights To WWE's 'Raw,' Its First Big Live Event (bloomberg.com) 80

Netflix has acquired the exclusive rights to Raw as well as other programming from World Wrestling Entertainment, marking the streaming service's first big move into live events. From a report: Raw will air on Netflix in the US, Canada, Latin America and other international markets beginning in January 2025, after the expiration of the WWE's domestic deal with Comcast. The company will also become the exclusive home outside the US for all WWE shows and specials, including Smackdown and NXT, as well as pay-per-view live events like Wrestlemania, SummerSlam and Royal Rumble. The pay-per-view events will be included at no additional cost for Netflix customers.

After attracting more than 200 million customers by offering films and TV shows on-demand, Netflix has now committed to offering three hours of live wrestling a week starting next year. The company hopes the deal will bring in millions of loyal WWE viewers and provide a boost for its fledgling advertising-supported plan. Netflix has been dabbling in live events for the last year, airing a live comedy special, as well as a golf match, but this is the first long-term rights deal. The WWE is the latest major live event to shift from cable TV to streaming. Ultimate Fighting Championship, which like WWE is owned by TKO Group Holdings, offers many of its matches on ESPN+, while the National Football League sold Amazon the rights to Thursday Night Football. A playoff game on Comcast's Peacock just delivered the largest streaming audience for any professional sports event in the US.
The deal 10-year deal is valued at more than $5 billion, CNBC reported.

Now Musicians' Union Threatens Possible Strike Over AI, Streaming Media (cnn.com) 64

"After a year in which both actors and writers hit the picket lines, another Hollywood strike may be on the horizon," reports CNN: The American Federation of Musicians (AFM), a union representing musicians across the entertainment industry, will begin negotiations Monday on a new contract with the Alliance of Motion Picture and Television Producers (AMPTP). The union said it is seeking a deal to better reflect the current state of streaming media. The AFM is also seeking AI protection, increased wages, health care improvements, improved working conditions and residual payments for streaming content. According to the AFM, musicians who record on soundtracks make 75% less on streaming content due to less residual income. "The entertainment industry has fundamentally shifted," the union said in a news release. But musicians "are not being compensated accordingly for streaming media." AFM's president and chief negotiator Tino Gagliardi told CNN the union "is going to be prepared to do whatever it needs to get what we have to have, in order to make the lives of musicians better..."

The AFM says it has roughly 70,000 members in the United States and Canada. Members include instrumental musicians working in orchestras, bands, clubs and theater who create music for film, television, commercials and other mediums.

Cop28 Deal Will Fail Unless Rich Countries Quit Fossil Fuels, Says Climate Negotiator 184

The credibility of the Cop28 agreement to "transition away" from fossil fuels rides on the world's biggest historical polluters like the US, UK and Canada rethinking current plans to expand oil and gas production, according to the climate negotiator representing 135 developing countries. The Guardian: In an exclusive interview with the Guardian, Pedro Pedroso, the outgoing president of the G77 plus China bloc of developing countries, warned that the landmark deal made at last year's climate talks in Dubai risked failing. "We achieved some important outcomes at Cop28 but the challenge now is how we translate the deal into meaningful action for the people," Pedroso said. "As we speak, unless we lie to ourselves, none of the major developed countries, who are the most important historical emitters, have policies that are moving away from fossil fuels, on the contrary, they are expanding," said Pedroso.

These countries must also deliver adequate finance for poorer nations to transition -and adapt to the climate crisis. In Dubai, Sultan Al Jaber, Cop28 president and chief of the Emirates national oil company, was subject to widespread scrutiny -- understandable given that the UAE is the world's seventh biggest oil producer with the fifth largest gas reserves. Yet the US was by far the biggest oil and gas producer in the world last year -- setting a new record, during a year that was the hottest ever recorded. The US, UK, Canada, Australia and Norway account for 51% of the total planned oil and gas expansion by 2050, according to research by Oil Change International. "It's very easy to label some emerging economies, especially the Gulf states, as climate villains, but this is very unfair by countries with historic responsibilities -- who keep trying to scapegoat and deviate the attention away from themselves. Just look at US fossil fuel plans and the UK's new drilling licenses for the North Sea, and Canada which has never met any of its emission reduction goals, not once," said Pedroso, a Cuban diplomat.

Beaver Ponds May Exacerbate Warming In Arctic, Scientists Say (theguardian.com) 95

An anonymous reader quotes a report from The Guardian: The stream through western Alaska never looked like this before. In aerial photography from the 1980s, it wove cleanly through the tundra, thin as thread. Today, in satellite images, it appears as a string of black patches: one large pond after another, dozens of meters apart. It's a transformation that is happening across the Arctic, the result of landscape engineering on an impressive scale. But this is no human endeavor to reshape the world. It is the work of the North American beaver, and there is no sign of it stopping. Were the waddling rodents making minor inroads, researchers may never have noticed. But the animals are pouring in, pushing north into new territories. The total number of animals is far from clear, but the ponds they create are hard to miss: in the Arctic tundra of Alaska alone, the number of beaver ponds on streams have doubled to at least 12,000 in the past 20 years. More lodges are dotted along lakes and river banks.

The preponderance of beavers, which can weigh as much as 45kg, follows a collapse in trapping and the warming of a landscape that once proved too bleak for occupation. Global heating has driven the shrubification of the Arctic tundra; the harsh winter is shorter, and there is more free-running water in the coldest months. Instead of felling trees for their dams, the beavers construct them from surrounding shrubs, creating deep ponds in which to build their lodges. The new arrivals cause plenty of disruption. For some communities, the rivers and streams are the roads of the landscape, and the dams make effective roadblocks. As the structures multiply, more land is flooded and there can be less fresh water for drinking downstream. But there are other, less visible effects too. The animals are participants in a feedback loop: climate change opens the landscape to beavers, whose ponds drive further warming, which attracts even more paddle-tailed comrades. Physics suggested this would happen. Beaver ponds are new bodies of water that cover bare permafrost. Because the water is warm -- relatively speaking -- it thaws the hard ground, which duly releases methane, one of the most potent greenhouse gases.

Scientists now have evidence this is happening. Armed with high-resolution satellite imagery, Tape and his colleagues located beaver ponds in the lower Noatak River basin area of north-western Alaska. They then analyzed infrared images captured by Nasa planes flying over the region. Overlaying the two revealed a clear link between beaver ponds and methane hotspots that extended for tens of meters around the ponds. "The transformation of these streams is a positive feedback that is accelerating the effects of climate change, and that is what's concerning," says Tape. "They are accelerating it at every one of these points." Because the Nasa images give only a snapshot in time, the researchers will head out next year to measure methane on the ground. With more measurements, they hope to understand how the emissions vary with the age of beaver ponds: do ponds release a steady flow of methane, or does the release wane after a decade or two?
"What's happening here is happening on a huge scale," says Ken Tape, an ecologist at the University of Alaska, Fairbanks, who is tracking the influx of beavers into the sparse northern landscape. "Our modeling work, which is in progress right now, shows that this entire area, the north slope of Alaska, will be colonized by beavers by 2100."

Earth Shattered Global Heat Record In 2023 (apnews.com) 227

The European climate agency Copernicus said Earth shattered global annual heat records in 2023, flirting with the world's agreed-upon warming threshold of 1.5 degrees Celsius. "On average, global temperatures in 2023 were 1.48 degrees Celsius higher than pre-industrial times," reports the Associated Press. "If annual averages reach above 1.5 degrees Celsius, the effects of global warming could become irreversible, climate scientists say." From the report: The record heat made life miserable and sometimes deadly in Europe, North America, China and many other places last year. But scientists say a warming climate is also to blame for more extreme weather events, like the lengthy drought that devastated the Horn of Africa, the torrential downpours that wiped out dams and killed thousands in Libya and the Canada wildfires that fouled the air from North America to Europe. In a separate Tuesday press event, international climate scientists who calculate global warming's role in extreme weather, the group's leader, Imperial College climate scientist Friederike Otto said "we definitely see in our analysis the strong impact of it being the hottest year."

The World Weather Attribution team only looks at events that affect at least 1 million people or kill more than 100 people. But Otto said her team was overwhelmed with more than 160 of those in 2023, and could only conduct 14 studies, many of them on killer heat waves. "Basically every heat wave that is occurring today has been made more likely and is hotter because of human-induced climate change," she said.
