France Pushes Back Plastic Cup Ban By Four Years (straitstimes.com) 42

An anonymous reader shares a report: The French government on Dec 30 postponed a ban on plastic throwaway cups by four years to 2030 because of difficulties finding alternatives. The ban was meant to start on Jan 1. But the Ministry for Ecological Transition said the "technical feasibility of eliminating plastic from cups" following a review in 2025 justified pushing back the deadline.

It said in an official decree that a new review would be carried out in 2028 of "progress made in replacing single-use plastic cups." It added that the ban would now start Jan 1, 2030, when companies would have 12 months to get rid of their stock. France has gradually rolled out bans on single-use plastic products over the past decade as environmental campaigners have stepped up warnings about the impact on rivers and oceans.

Nepal To Scrap 'Failed' Mount Everest Waste Deposit Scheme (bbc.com) 59

A scheme to encourage climbers to bring their waste down from Mount Everest is being scrapped -- with Nepalese authorities telling the BBC it has been a failure. From the report: Climbers had been required to pay a deposit of $4,000, which they would only get back if they brought at least 8kg (18lbs) of waste back down with them. It was hoped it would begin to tackle the rubbish problem on the world's highest peak, which is estimated to be covered in some 50 tonnes of waste. But after 11 years -- and with the rubbish still piling up -- the scheme is being shelved because it "failed to show a tangible result."

Stingless Bees From the Amazon Granted Legal Rights in World First (theguardian.com) 52

Stingless bees from the Amazon have become the first insects to be granted legal rights anywhere in the world, in a breakthrough supporters hope will be a catalyst for similar moves to protect bees elsewhere. From a report: It means that across a broad swathe of the Peruvian Amazon, the rainforest's long-overlooked native bees -- which, unlike their cousins the European honeybees, have no sting -- now have the right to exist and to flourish. Cultivated by Indigenous peoples since pre-Columbian times, stingless bees are thought to be key rainforest pollinators, sustaining biodiversity and ecosystem health.

But they are faced with a deadly confluence of climate change, deforestation and pesticides, as well as competition from European bees, and scientists and campaigners have been racing against time to get stingless bees on international conservation red lists. Constanza Prieto, Latin American director at the Earth Law Center, who was part of the campaign, said: "This ordinance marks a turning point in our relationship with nature: it makes stingless bees visible, recognises them as rights-bearing subjects, and affirms their essential role in preserving ecosystems."

There Was Some Good News on Green Energy in 2025 (msn.com) 40

Yes, greenhouse gas emissions kept rising in 2025, writes Bloomberg (alternate URL here). And the pledges of various governments to lower greenhouse gases "are nowhere near where they need to be to avoid catastrophic climate change..."

But in 2025, "there were silver linings too." The world is decarbonizing faster than was expected 10 years ago and investment into the clean energy transition, including everything from wind and solar to batteries and grids, is expected to have reached a new record of $2.2 trillion globally in 2025, according to research by the Energy & Climate Intelligence Unit, a London nonprofit. "Is this enough to keep us safe? No it clearly isn't," said Gareth Redmond-King, international lead at the ECIU. "Is it remarkable progress compared to where we were headed? Clearly it is...." Global investment in clean tech far outpaced what went into polluting industries. For every $1 funding fossil fuel projects, $2 went into clean power, according to the ECIU. For China, the EU, the U.S. and India, the four largest polluters, it was $2.60.

Funds flowing into renewable power set another record in the first half of this year and were up 10% compared to the same period in 2024, to $386 billion, according to the latest available research by BloombergNEF. Solar and wind grew fast enough to meet all new electricity demand globally in the first three quarters of 2025, according to UK-based energy think tank Ember. That means renewable capacity is set to hit a new record globally this year, with Ember forecasting an 11% increase from 2024. Over the last three years, renewable capacity grew by nearly 30% on average. That puts the world within reach of the goal set at COP 28 in Dubai in 2023 to triple clean power by 2030. China is leading the charge, with the world's largest polluter expected to have delivered 66% of new solar capacity, and 69% of new wind globally this year, according to Ember. Renewables also advanced in parts of Asia, Europe and South America.

The explosive power demand from artificial intelligence is also turning the tide on green technology investment, which had soured in recent years. For the first three quarters of this year, global clean tech investment, which was dominated by funding in next-generation nuclear reactors, renewables and other solutions that help power data centers, has already surpassed all of 2024. That marks the sector's first annual increase since the 2022 peak. And despite President Trump's rollback of climate policies, the S&P's main gauge tracking clean energy is up about 50% this year, outperforming most other stock indexes and even gold. That same enthusiasm has also helped channel more capital into developing and upgrading the power grid, a backbone of the global energy transition.

The article also notes that prices per kilowatt-hour of battery capacity "fell by 8% to a record $108 this year and they're expected to decline a further 3% next year, according to BloombergNEF."

And this year the International Court of Justice "determined that countries risk being in violation of international law if they don't work toward keeping global warming to the 1.5C threshold agreed on at the Paris climate conference in 2015."

Should Physicists Study the Question: What is Life? (msn.com) 89

An astrophysicist at the University of Rochester writes that "many" of his colleagues in physics "have come to believe that a mystery is unfolding in every microbe, animal, and human." And it's a mystery that:

- "Challenges basic assumptions physicists have held for centuries"
- "May even help redefine the field for the next generation"
- "Could answer essential questions about AI."

In short, while physicists have favored a "reductionist" philosophy about the fundamental laws controlling the universe (energy, mattery, space, and time), "long-promised 'theories of everything' such as string theory, have not borne significant fruit: There are, however, ways other than reductionism to think about what's fundamental in the universe. Beginning in the 1980s, physicists (along with researchers in other fields) began developing new mathematical tools to study what's called "complexity" — systems in which the whole is far more than the sum of its parts. The end goal of reductionism was to explain everything in the universe as the result of particles and their interactions. Complexity, by contrast, recognizes that once lots of particles come together to produce macroscopic things — such as organisms — knowing everything about particles isn't enough to understand reality...

Physicists have always been good at capturing the essential aspects of a system and casting those essentials in the language of mathematics... Now those skills must be brought to bear on an age-old question that is only just getting its proper due: What is life? Using these skills, physicists — working together with representatives of all the other disciplines that make up complexity science — may crack open the question of how life formed on Earth billions of years ago and how it might have formed on the distant alien worlds we can now explore with cutting-edge telescopes. Just as important, understanding why life, as an organized system, is different at a fundamental level from all the other stuff in the universe may help astronomers design new strategies for finding it in places bearing little resemblance to Earth. Analyzing life — no matter how alien — as a self-organizing information-driven system may provide the key to detecting biosignatures on planets hundreds of light-years away.

Closer to home, studying the nature of life is likely essential to fully understanding intelligence — and building artificial versions. Throughout the current AI boom, researchers and philosophers have debated whether and when large language models might achieve general intelligence or even become conscious — or whether, in fact, some already have. The only way to properly assess such claims is to study, by any means possible, the sole agreed-upon source of general intelligence: life. Bringing the new physics of life to problems of AI may not only help researchers predict what software engineers can build; it may also reveal the limits of trying to capture life's essential character in silicon.

Russia Plans a Nuclear Power Plant on the Moon Within a Decade (reuters.com) 43

Russia plans to put a nuclear power plant on the moon in the next decade to supply its lunar space programme and a joint Russian-Chinese research station, as major powers rush to explore the earth's only natural satellite. Reuters: Ever since Soviet cosmonaut Yuri Gagarin became the first human to go into space in 1961, Russia has prided itself as a leading power in space exploration, but in recent decades it has fallen behind the United States and, increasingly, China. Russia's ambitions suffered a massive blow in August 2023 when its unmanned Luna-25 mission smashed into the surface of the moon while attempting to land, and Elon Musk has revolutionised the launch of space vehicles - once a Russian speciality.

Russia's state space corporation, Roscosmos, said in a statement that it planned to build a lunar power plant by 2036 and signed a contract with the Lavochkin Association aerospace company to do it. Roscosmos did not say explicitly that the plant would be nuclear but it said the participants included Russian state nuclear corporation Rosatom and the Kurchatov Institute, Russia's leading nuclear research institute. Roscosmos said the purpose of the plant was to power Russia's lunar programme, including rovers, an observatory and the infrastructure of the joint Russian-Chinese International Lunar Research Station.

Safety Panel Says NASA Should Have Taken Starliner Incident More Seriously (arstechnica.com) 37

joshuark shares a report from Ars Technica: For the better part of two months last year, most of us had no idea how serious the problems were with Boeing's Starliner spacecraft docked at the International Space Station. A safety advisory panel found this uncertainty also filtered through NASA's workforce. [...] The Starliner capsule was beset by problems with its maneuvering thrusters and pernicious helium leaks on its 27-hour trip from the launch pad to the ISS. For a short time, Starliner commander Wilmore lost his ability to control the movements of his spacecraft as it moved in for docking at the station in June 2024. Engineers determined that some of the thrusters were overheating and eventually recovered most of their function, allowing Starliner to dock with the ISS. [...]

Throughout that summer, managers from NASA and Boeing repeatedly stated that the spacecraft was safe to bring Wilmore and Williams home if the station needed to be evacuated in an emergency. But officials on the ground ordered extensive testing to understand the root of the problems. Buried behind the headlines, there was a real chance NASA managers would decide -- as they ultimately did -- not to put astronauts on Boeing's crew capsule when it was time to depart the ISS. [...] It would have been better, [Charlie Precourt, a former space shuttle commander and now a member of NASA's Aerospace Safety Advisory Panel (ASAP)] and other panel members said Friday, if NASA made a formal declaration of an in-flight "mishap" or "high visibility close call" soon after the Starliner spacecraft's troubled rendezvous with the ISS. Such a declaration would have elevated responsibility for the investigation to NASA's safety office. [...]

After months of testing and analysis, NASA officials were unsure if the thruster problems would recur on Starliner's flight home. They decided in August 2024 to return the spacecraft to the ground without the astronauts, and the capsule safely landed in New Mexico the following month. The next Starliner flight will carry only cargo to the ISS. The safety panel recommended that NASA review its criteria and processes to ensure the language is "unambiguous" in requiring the agency to declare an in-flight mishap or a high-visibility close call for any event involving NASA personnel "that leads to an impact on crew or spacecraft safety."

Military Satellites Now Maneuver, Watch Each Other, and Monitor Signals and Data (msn.com) 15

An anonymous reader shared this report from the Washington Post. (Alternate URL here): The American patrol satellite had the targets in its sights: two recently launched Chinese spacecraft flying through one of the most sensitive neighborhoods in space. Like any good tactical fighter, the American spacecraft, known as USA 270, approached from behind, so that the sun would be at its back, illuminating the quarry.

But then one of the Chinese satellites countered by slowing down. As USA 270 zipped by, the Chinese satellite dropped in behind its American pursuer, like Maverick's signature "hit-the-brakes" move in the movie "Top Gun." The positions reversed, U.S. officials controlling their spacecraft from Earth were forced to plot their next move. The encounter some 22,000 miles above Earth in 2022 was never acknowledged publicly by the Pentagon or Beijing. Happening out of sight and little noticed except by space and defense specialists, this kind of orbital skirmishing has become so common that defense officials now refer to it as "dogfighting..."

Much of the "dogfighting" activity in space is simply for spying, defense analysts say, with specifics largely classified — snapping photos of each other's satellites to learn what kind of systems are on board and their capabilities. They monitor the signals and data emitted by satellites, listening to communications between space and the ground. Many can even jam those signals or interfere with orbiting craft that provide missile warnings, spy or relay critical information to troops... Traditionally, once a satellite was in orbit, it largely stayed on a fixed path, its operators reluctant to burn precious fuel. But now, the Pentagon and its adversaries, notably China and Russia, are launching satellites designed to fly in more dynamic ways that resemble aircraft — banking hard, slowing down, speeding up, even flying in tandem.

"Traditionally satellites weren't designed to fight, and they weren't designed to protect themselves in a fight," said Clinton Clark, the chief growth officer of ExoAnalytic Solutions, a company that monitors activity in space. "That is all changing now."

"Unlike dogfights between fighter jets, the jockeying-for-position encounters in orbit take place over several hours, even days," the article points out.

But it also notes that recently Germany's defense minister "complained about a Russian satellite that had been flying close to a commercial communications satellite used by the German military. 'They can jam, blind, manipulate or kinetically disrupt satellites,' he said."

Trump Dismantling National Center For Atmospheric Research In Colorado (pbs.org) 284

echo123 shares a report from PBS: The Trump administration is dismantling the National Center for Atmospheric Research in Colorado, moving to dissolve a research lab that a top White House official described as "one of the largest sources of climate alarmism in the country." White House budget director Russ Vought criticized the lab in a social media post Tuesday night and said a comprehensive review of the lab is underway. "Vital activities such as weather research will be moved to another entity or location, Vought said.

The research lab, which houses the largest federal research program on climate change, supports research to predict, prepare for and respond to severe weather and other natural disasters. The research lab is managed by a nonprofit consortium of more than 130 colleges and universities on behalf of the National Science Foundation. A senior White House official cited two instances of the lab's "woke direction" that wastes taxpayer funds on what the official called frivolous pursuits and ideologies. One funded an Indigenous and Earth Sciences center that aimed to "make the sciences more welcoming, inclusive, and justice-centered," while another experiment traced air pollution to "demonize motor vehicles, oil and gas operations."
The lab "is quite literally our global mothership," said Katharine Hayhoe, a climate scientist and Distinguished Professor at Texas Tech University, in a post on X. "Nearly everyone who researches climate and weather -- not only in the U.S., but around the world -- has passed through its doors and benefited from its incredible resources."

She continued: "NCAR supports the scientists who fly into hurricanes, the meteorologists who develop new radar technology, the physicists who envision and code new weather models, and yes -- the largest community climate model in the world. That too. Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet."

James Webb Space Telescope Confirms 1st 'Runaway' Supermassive Black Hole (space.com) 36

Longtime Slashdot reader schwit1 shares a report from Space.com: Astronomers have made a truly mind-boggling discovery using the James Webb Space Telescope (JWST): a runaway black hole 10 million times larger than the sun, rocketing through space at a staggering 2.2 million miles per hour (1,000 kilometers per second). That not only makes this the first confirmed runaway supermassive black hole, but this object is also one of the fastest-moving bodies ever detected, rocketing through its home, a pair of galaxies named the "Cosmic Owl," at 3,000 times the speed of sound at sea level here on Earth. If that isn't astounding enough, the black hole is pushing forward a literal galaxy-sized "bow-shock" of matter in front of it, while simultaneously dragging a 200,000 light-year-long tail behind it, within which gas is accumulating and triggering star formation. "It boggles the mind!" discovery team leader Pieter van Dokkum of Yale University told Space.com. "The forces that are needed to dislodge such a massive black hole from its home are enormous. And yet, it was predicted that such escapes should occur!"

"This is the only black hole that has been found far away from its former home," van Dokkum said. "That made it the best candidate [for a] runaway supermassive black hole, but what was missing was confirmation. All we really had was a streak that was difficult to explain in any other way. With the JWST, we have now confirmed that there is indeed a black hole at the tip of the streak, and that it is speeding away from its former host."

The research is currently available as a pre-peer-reviewed paper on arXiv.

2026 Will Bring Heat More Than 1.4C Above Preindustrial Levels, UK Met Office Says (theguardian.com) 48

The UK Met Office projects that 2026 will see global temperatures rise between 1.34C and 1.58C above preindustrial levels, placing it among the four hottest years since records began in 1850 and continuing a streak of extreme warming that has pushed the planet into unprecedented territory. The central forecast is slightly cooler than the 1.55C recorded in 2024, the warmest year on record. But climate scientist Adam Scaife, who led the forecast, noted that "the last three years are all likely to have exceeded 1.4C" and 2026 would be the fourth consecutive year to do so. "Prior to this surge, the previous global temperature had not exceeded 1.3C," he said.

The forecast suggests another temporary exceedance of the 1.5C threshold set by the Paris Agreement is possible in 2026, following the first such breach in 2024. The 1.5C target is measured as a 30-year average, so it remains technically achievable even as individual years cross the line. EU scientists said last week that 2025 is "virtually certain" to rank as the second or third-hottest year on record.

The Arctic Is in Dire Straits, 20 Years of Reporting Show 57

A new Arctic Report Card recap shows how the Arctic has transformed in just 20 years, warming about twice as fast as the global average and losing most of its oldest sea ice. It's also triggering cascading impacts from "Atlantification" to permafrost-driven "rusting rivers" and more destructive storms. Scientific American reports: The first Arctic Report Card was released by the National Oceanic and Atmospheric Administration in 2006. Since then the region has warmed twice as fast as the global average. About 95 percent of the oldest, thickest sea ice is gone -- "the sliver that remains is collected in an area north of Greenland. Even the central Arctic Ocean is becoming warmer and saltier, causing more ice melt and changing how much heat is released into the atmosphere in a way that affects weather patterns around the world. Those are just some of the stark changes 20 years have wrought. The findings were highlighted in the 2025 Arctic Report Card, released on Tuesday.

The Arctic Ocean is undergoing what scientists are calling "Atlantification" -- a process where warm, salty water from the Atlantic flows north, changing how waters of different temperatures and densities are layered in the Arctic, disrupting ecosystems and altering how heat moves from the water to the air. [...] The Arctic is simply becoming wetter, with more precipitation falling as rain instead of snow. June snow cover over the entire Arctic is half of what it was 60 years ago, the report found. Permafrost also continues to thaw, releasing once trapped carbon into the atmosphere and disgorging iron and other elements that have turned rivers and streams orange. These "rusting rivers," found in more than 200 watersheds, are more acidic than normal and have elevated levels of toxic metals that endanger local ecosystems. And as the permafrost thaws, the tundra of the Arctic biome is shrinking, and the boreal forest biome is creeping northward, disrupting ecosystems.

Glaciers To Reach Peak Rate of Extinction In the Alps In Eight Years 24

A new study warns that glaciers in the European Alps will hit their peak extinction rate within eight years, with global glacier loss accelerating toward thousands per year unless emissions are rapidly cut. "Glaciers in the western US and Canada are forecast to reach their peak year of loss less than a decade later, with more than 800 disappearing each year by then," adds the Guardian. From the report: About 200,000 glaciers remain worldwide, with about 750 disappearing each year. However, the research indicates this pace will accelerate rapidly as emissions from burning fossil fuels continue to be released into the atmosphere. Current climate action plans from governments are forecast to push global temperatures to about 2.7C above preindustrial levels, supercharging extreme weather. Under this scenario, glacier losses would peak at about 3,000 a year in 2040 and plateau at that rate until 2060. By the end of the century, 80% of today's glaciers will have gone. By contrast, rapid cuts to carbon emissions to keep global temperature rise to 1.5C would cap annual losses at about 2,000 a year in 2040, after which the rate would decline. [...]

The new study, published in Nature Climate Change, analyzed more than 200,000 glaciers from a database of outlines derived from satellite images. The researchers used three global glacier models to assess their fate under different heating scenarios. Regions with the smallest and fastest-melting glaciers were found to be the most vulnerable. The study estimates the 3,200 glaciers in central Europe would shrink by 87% by 2100 -- even if global temperature rise is limited to 1.5C, rising to 97% under 2.7C of heating.

In the western US and Canada, including Alaska, about 70% of today's 45,000 glaciers are projected to vanish under 1.5C of heating, and more than 90% under 2.7C. The Caucasus and southern Andes are also expected to face devastating losses. Larger glaciers take longer to melt, with those in Greenland reaching their peak extinction rate in about 2063 -- losing 40% by 2100 under 1.5C of heating and 59% under 2.7C. However, the melting is forecast to continue beyond 2100. The researchers said the peak loss dates represent more than a numerical milestone. "They mark turning points with profound implications for ecosystems, water resources and cultural heritage," they wrote. "[It is] a human story of vanishing landscapes, fading traditions and disrupted daily routines."

China, Iran Are Having a Field Day With React2Shell, Google Warns (theregister.com) 30

A critical React vulnerability (CVE-2025-55182) is being actively exploited at scale by Chinese, Iranian, North Korean, and criminal groups to gain remote code execution, deploy backdoors, and mine crypto. The Register reports: React maintainers disclosed the critical bug on December 3, and exploitation began almost immediately. According to Amazon's threat intel team, Chinese government crews, including Earth Lamia and Jackpot Panda, started battering the security hole within hours of its disclosure. Palo Alto Networks' Unit 42 responders have put the victim count at more than 50 organizations across multiple sectors, with attackers from North Korea also abusing the flaw.

Google, in a late Friday report, said at least five other suspected PRC spy groups also exploited React2Shell, along with criminals who deployed XMRig for illicit cryptocurrency mining, and "Iran-nexus actors," although the report doesn't provide any additional details about who the Iran-linked groups are and what they are doing after exploitation. "GTIG has also observed numerous discussions regarding CVE-2025-55182 in underground forums, including threads in which threat actors have shared links to scanning tools, proof-of-concept (PoC) code, and their experiences using these tools," the researchers wrote.

Why Floods Threaten One of the Driest Places in the World (washingtonpost.com) 35

One of the most water-scarce regions on Earth is now experiencing a dramatic atmospheric shift that's pushing moisture onto Oman's northern coast at rates more than 1.5 times the global average, according to a Washington Post investigation of global atmospheric data [non-paywalled source]. The change has turned extreme rainfall into a recurrent source of catastrophe across the Arabian Peninsula. In the 126 years between 1881 and 2007, just six hurricane-strength storms hit Oman or came within 60 miles of the country. At least four more have made landfall in the past 15 years alone.

Research from Sultan Qaboos University analyzing 8,000 storms across 69 rainfall stations found that half of all rain in Oman falls within the first 90 minutes of a 24-hour storm. These intense bursts quickly overwhelm the desert's ability to absorb water and send flash floods racing through wadis -- normally dry riverbeds where many communities are built. In response, Dubai is constructing an $8 billion underground stormwater network spanning more than 120 miles. Oman has agreements to build 58 new dams and is studying 14 major wadis that funnel to its al-Batinah coastline.

SpaceX Alleges a Chinese-Deployed Satellite Risked Colliding with Starlink (pcmag.com) 45

"A SpaceX executive says a satellite deployed from a Chinese rocket risked colliding with a Starlink satellite," reports PC Magazine: On Friday, company VP for Starlink engineering, Michael Nicolls, tweeted about the incident and blamed a lack of coordination from the Chinese launch provider CAS Space. "When satellite operators do not share ephemeris for their satellites, dangerously close approaches can occur in space," he wrote, referring to the publication of predicted orbital positions for such satellites...

[I]t looks like one of the satellites veered relatively close to a Starlink sat that's been in service for over two years. "As far as we know, no coordination or deconfliction with existing satellites operating in space was performed, resulting in a 200 meter (656 feet) close approach between one of the deployed satellites and STARLINK-6079 (56120) at 560 km altitude," Nicolls wrote... "Most of the risk of operating in space comes from the lack of coordination between satellite operators — this needs to change," he added.

Chinese launch provider CAS Space told PCMag that "As a launch service provider, our responsibility ends once the satellites are deployed, meaning we do not have control over the satellites' maneuvers."

And the article also cites astronomer/satellite tracking expert Jonathan McDowell, who had tweeted that CAS Space's response "seems reasonable." (In an email to PC Magazine, he'd said "Two days after launch is beyond the window usually used for predicting launch related risks."

But "The coordination that Nicolls cited is becoming more and more important," notes Space.com, since "Earth orbit is getting more and more crowded." In 2020, for example, fewer than 3,400 functional satellites were whizzing around our planet. Just five years later, that number has soared to about 13,000, and more spacecraft are going up all the time. Most of them belong to SpaceX. The company currently operates nearly 9,300 Starlink satellites, more than 3,000 of which have launched this year alone.

Starlink satellites avoid potential collisions autonomously, maneuvering themselves away from conjunctions predicted by available tracking data. And this sort of evasive action is quite common: Starlink spacecraft performed about 145,000 avoidance maneuvers in the first six months of 2025, which works out to around four maneuvers per satellite per month. That's an impressive record. But many other spacecraft aren't quite so capable, and even Starlink satellites can be blindsided by spacecraft whose operators don't share their trajectory data, as Nicolls noted.

And even a single collision — between two satellites, or involving pieces of space junk, which are plentiful in Earth orbit as well — could spawn a huge cloud of debris, which could cause further collisions. Indeed, the nightmare scenario, known as the Kessler syndrome, is a debris cascade that makes it difficult or impossible to operate satellites in parts of the final frontier.

Polar Bears are Rewiring Their Own Genetics to Survive a Warming Climate (nbcnews.com) 27

"Polar bears are still sadly expected to go extinct this century," with two-thirds of the population gone by 2050," says the lead researcher on a new study from the University of East Anglia in Britain.

But their research also suggests polar bears "are rapidly rewiring their own genetics in a bid to survive," reports NBC News, in "the first documented case of rising temperatures driving genetic change in a mammal." "I believe our work really does offer a glimmer of hope — a window of opportunity for us to reduce our carbon emissions to slow down the rate of climate change and to give these bears more time to adapt to these stark changes in their habitats," [the lead author of the study told NBC News].

Building on earlier University of Washington research, [lead researcher] Godden's team analyzed blood samples from polar bears in northeastern and southeastern Greenland. In the slightly warmer south, they found that genes linked to heat stress, aging and metabolism behaved differently from those in northern bears. "Essentially this means that different groups of bears are having different sections of their DNA changed at different rates, and this activity seems linked to their specific environment and climate," Godden said in a university press release. She said this shows, for the first time, that a unique group of one species has been forced to "rewrite their own DNA," adding that this process can be considered "a desperate survival mechanism against melting sea ice...."

Researchers say warming ocean temperatures have reduced vital sea ice platforms that the bears use to hunt seals, leading to isolation and food scarcity. This led to genetic changes as the animals' digestive system adapts to a diet of plants and low fats in the absence of prey, Godden told NBC News.

Startup Successfully Uses AI to Find New Geothermal Energy Reservoirs (cnn.com) 50

A Utah-based startup announced last week it used AI to locate a 250-degree Fahrenheit geothermal reservoir, reports CNN. It'll start producing electricity in three to five years, the company estimates — and at least one geologist believes AI could be an exciting "gamechanger" for the geothermal industry. [Startup Zanskar Geothermal & Minerals] named it "Big Blind," because this kind of site — which has no visual indication of its existence, no hot springs or geysers above ground, and no history of geothermal exploration — is known as a "blind" system. It's the first industry-discovered blind site in more than three decades, said Carl Hoiland, co-founder and CEO of Zanskar. "The idea that geothermal is tapped out has been the narrative for decades," but that's far from the case, he told CNN. He believes there are many more hidden sites across the Western U.S.

Geothermal energy is a potential gamechanger. It offers the tantalizing prospect of a huge source of clean energy to meet burgeoning demand. It's near limitless, produces scarcely any climate pollution, and is constantly available, unlike wind and solar, which are cheap but rely on the sun shining and the wind blowing. The problem, however, has been how to find and scale it. It requires a specific geology: underground reservoirs of hot water or steam, along with porous rocks that allow the water to move through them, heat up, and be brought to the surface where it can power turbines... The AI models Zanskar uses are fed information on where blind systems already exist. This data is plentiful as, over the last century and more, humans have accidentally stumbled on many around the world while drilling for other resources such as oil and gas.

The models then scour huge amounts of data — everything from rock composition to magnetic fields — to find patterns that point to the existence of geothermal reserves. AI models have "gotten really good over the last 10 years at being able to pull those types of signals out of noise," Hoiland said...

Zanskar's discovery "is very significant," said James Faulds, a professor of geosciences at Nevada Bureau of Mines and Geology.... Estimates suggest over three-quarters of US geothermal resources are blind, Faulds told CNN. "Refining methods to find such systems has the potential to unleash many tens and perhaps hundreds of gigawatts in the western US alone," he said... Big Blind is the company's first blind site discovery, but it's the third site it has drilled and hit commercial resources. "We expect dozens, to eventually hundreds, of new sites to be coming to market," Hoiland said.... Hoiland says Zanskar's work shows conventional geothermal still has huge untapped potential.

97% of Buildings On Earth 3D-Mapped (nature.com) 34

Longtime Slashdot reader Gilmoure shares a report from Nature: Scientists have produced the most detailed 3D map of almost all buildings in the world. The map, called GlobalBuildingAtlas, combines satellite imagery and machine learning to generate 3D models for 97% of buildings on Earth. The dataset, published in the open-access journal Earth System Science Data on December 1, covers 2.75 billion buildings, each mapped with footprints and heights at a spatial resolution of 3 meters by 3 meters. The 3D map opens new possibilities for disaster risk assessment, climate modeling and urban planning, according to study co-author Xiaoxiang Zhu, an Earth observation data scientist at the Technical University of Munich in Germany. "Imagine a video game with the world's buildings already mapped in basic spatial dimensions!" writes Gilmoure.

'Food and Fossil Fuel Production Causing $5 Billion of Environmental Damage an Hour' 121

An anonymous reader quotes a report from the Guardian: The unsustainable production of food and fossil fuels causes $5 billion of environmental damage per hour, according to a major UN report. Ending this harm was a key part of the global transformation of governance, economics and finance required "before collapse becomes inevitable," the experts said. The Global Environment Outlook (GEO) report, which is produced by 200 researchers for the UN Environment Program, said the climate crisis, destruction of nature and pollution could no longer be seen as simply environmental crises. "They are all undermining our economy, food security, water security, human health and they are also [national] security issues, leading to conflict in many parts of the world," said Prof Robert Watson, the co-chair of the assessment. [...]

The GEO report is comprehensive -- 1,100 pages this year -- and is usually accompanied by a summary for policymakers, which is agreed by all the world's countries. However, strong objections by countries including Saudi Arabia, Iran, Russia, Turkey and Argentina to references to fossil fuels, plastics, reduced meat in diets and other issues meant no agreement was reached this time. [...] The GEO report emphasized that the costs of action were much less than the costs of inaction in the long term, and estimated the benefits from climate action alone would be worth $20 trillion a year by 2070 and $100 trillion by 2100. "We need visionary countries and private sector [companies] to recognize they will make more profit by addressing these issues rather than ignoring them," Watson said. [...]

One of the biggest issues was the $45 trillion a year in environmental damage caused by the burning of coal, oil and gas, and the pollution and destruction of nature caused by industrial agriculture, the report said. The food system carried the largest costs, at $20 trillion, with transport at $13 trillion and fossil-fuel powered electricity at $12 trillion. These costs -- called externalities by economists -- must be priced into energy and food to reflect their real price and shift consumers towards greener choices, Watson said: "So we need social safety nets. We need to make sure that the poorest in society are not harmed by an increase in costs." The report suggests measures such as a universal basic income, taxes on meat and subsidies for healthy, plant-based foods.

There were also about $1.5 trillion in environmentally harmful subsidies to fossil fuels, food and mining, the report said. These needed to be removed or repurposed, it added. Watson noted that wind and solar energy was cheaper in many places but held back by vested interests in fossil fuel. The climate crisis may be even worse than thought, he said: "We are likely to be underestimating the magnitude of climate change," with global heating probably at the high end of the projections made by the Intergovernmental Panel on Climate Change. Removing fossil fuel subsidies could cut emissions by a third, the report said.
