'Off the Charts' El Nino Is Already the Strongest Since Records Began

Par : BeauHD

A rapidly developing El Nino is already reaching record-setting levels for this time of year and is expected to intensify further over the coming months. "The El Nino has blossomed. It is off the charts. Usual measures of El Nino have blown past prior record levels in the period with good data, even though maximum effects are still several months in the future," writes renowned climate scientist James Hansen at Columbia University in New York in a newsletter sent today. Climate scientists disagree over whether it has already surpassed previous "super El Nino" events on every metric, but several say the signal is unprecedented in forecasts and could ultimately become the strongest modern event on record. New Scientist reports: There are different ways of measuring El Ninos, which occur when warm surface waters spread eastwards along the equator across the surface of the tropical Pacific Ocean. Hansen thinks the best measure is how much warmer than usual the upper 300 meters of the eastern tropical Pacific becomes. "Our preferred metric, the heat anomaly in the upper 300 meters of the Equatorial Pacific Ocean... already exceeds the 1997-98 super El Nino," he writes. [...] What's clear is that this developing super El Nino will soon exceed previous events on all measures. "I have never seen an El Nino signal this intense in our forecasts," [Adam Scaife at the Met Office, the UK's national weather service] said in a statement released today. "If the forecast is accurate... then 2026 will far exceed our recent experience of El Nino and its worldwide climate influences." While Hansen is comparing the developing super El Nino to other modern events for which we have direct temperature records, Hayley Fowler at Newcastle University in the UK thinks it could also exceed historical events suspected to be even larger. "The super El Nino evolving in the Pacific will likely be the biggest ever recorded, reaching or exceeding the levels of the 1877-1878 El Nino which caused widespread impacts, including famines and around 50 million deaths (3-4 percent of the global population at the time), mostly across Asia and South America," Fowler said in a statement.

Why Europe Keeps Being Pummeled by Heat Waves

15 août 2026 à 23:34
Europe is facing its fifth round of dangerously high temperatures this summer, the New York Times reports. Now climate scientists wonder if global warming is doing more than raise temperatures... The weather patterns that create heat domes aren't new, but today they arise on top of the warming caused by greenhouse gas emissions. That makes it more likely that heat waves reach record-shattering temperatures for long stretches. But other environmental changes — natural, human-influenced or both — might also be causing heat domes to become more frequent and longer lasting. And it's these changes that scientists around the globe are trying to puzzle out. One change has to do with the Arctic. The differences in temperature between the hot Equator and the frigid far north help keep weather moving around the Northern Hemisphere. But with the top of the world now warming at several times the pace of the rest of the globe, those temperature gradients are narrowing. That might be causing the movements of weather systems to become more sluggish, producing more persistent heat waves. In Europe, reduced air pollution could be having a similar effect. Industrial emissions can contain particles called aerosols that reflect sunlight. Curbing aerosols has improved air quality, but it may also have altered the way air moves across the continent. Scientists haven't come to firm conclusions about how these shifts might be affecting European summers, said Antje Weisheimer, a climate scientist at the University of Oxford. The complex, fine-scale interactions in the atmosphere that drive weather dynamics are tough to capture in computer simulations, Dr. Weisheimer said. "It's tricky," she said. "We're making small progress." Dim Coumou, a professor of climate science at the Dutch university VU Amsterdam, sees artificial intelligence as one way forward. In a recent study, he and his colleagues used an A.I. algorithm to help a weather model better predict summer temperatures in Europe. They not only improved the model's forecasts; they also discovered why some of the model's predictions had been off: It misrepresented the way conditions in the western Pacific Ocean influenced atmospheric patterns that eventually made their way to Europe. With A.I., "we can also learn what the climate models are missing," Dr. Coumou said.

"The European Union's Copernicus climate monitoring service confirmed Monday that June and July were the hottest on record in western Europe," .according to a report from the CBC. "The period saw an estimated 25,000 heat-related deaths." CNN has before-and-after photos of Europe's dried rivers, calling it "a crisis so dire it can be seen from space" River levels are so low that commercial ships have had to reduce their loads by as much as 80% to avoid running aground. It's disrupting supply chains and making shipping more expensive. Other effects of Europe's drying rivers The BBC reports that Romania has "shut down its only nuclear power station because of extremely low water levels in the Danube river." A bridge built in the year 39 AD by the Roman emperor Caligula "is usually entirely underwater," reports CNN, but this year full blocks of the ancient structure are visible, giving archaeologists a rare opportunity to study it." The reports adds that drying Tiber has also now also revealed formerly submerged e-bikes, scooters, refrigerators and a car." The CBC reports a dozen Nazi warships scuttled in a river during the Second World War are now resurfacing as water levels plunge. "Elsewhere, the drying Danube has revealed a German military motorcycle in Hungary, an unexploded 700-kilogram British bomb in Slovakia, and what are believed to be the ancient remains of a mammoth in Bulgaria."

How Social Media Spurred a Refugee Crisis Between Spain and Morocco

13 août 2026 à 03:30
An anonymous reader quotes a report from The New York Times: Two days before tens of thousands of migrants surged into Ceuta, one of Spain's enclaves on Morocco's northern coast, a newspaper there posted a video on TikTok and Instagram showing two young women walking in the city in wet suits, their hair still damp. The posts didn't say so explicitly, but the implication was clear: The women had just swum across the border from Morocco. "Ceuta can't take it anymore," the newspaper, El Faro de Ceuta, declared in the posts. On the other side of the border, the video resonated very differently. Cropped and reposted in Arabic, the video seemed like an invitation. The women were smiling, flashing peace signs and thumbs up and, most of all, walking around freely. The video seemed to legitimize rumors that had percolated for weeks on social media suggesting that a recent ruling by Spain's Supreme Court meant migrants who arrived illegally by sea could stay in the country. As one account on Facebook put it, falsely, "Ceuta is turning into an open gate," when in fact migrants still faced expulsion after a judicial review. The responses to the posts about the swimmers were a critical part of a cascade of disinformation that experts described as one of the starkest instances in which social media contributed directly to a real-world tragedy.

Contiguous US Breaks Its Record For Hottest Month Ever, NOAA Says

Par : BeauHD
12 août 2026 à 03:30
An anonymous reader quotes a report from the Associated Press: The contiguous United States sizzled to its hottest month ever last month, according to the National Oceanic and Atmospheric Administration. July averaged 76.89 degrees Fahrenheit (24.94 degrees Celsius) across the Lower 48 states, eclipsing the Dust Bowl's July 1936 by an eighth of a degree. Records go back to 1895. [...] Although it was unusually cool in Alaska, hotter-than-normal conditions blanketed the Lower 48, with the most excessive heat in the Mountain West, Southwest, Northern Plains and Southeast. The heat was so widespread that every one of the Lower 48 states was at least 1 degree Fahrenheit (nearly 0.6 degrees Celsius) warmer than the 20th century average, said Russ Vose, chief of monitoring at NOAA's National Center for Environmental Information. [...] The biggest driver of the record heat was nighttime lows that smashed the old mark for hottest minimums by 0.7 degrees, NOAA said. Hotter nights are a classic sign of human-caused climate change, according to scientists and several studies in peer-reviewed literature. NOAA's calculation is based on averaging 24 hours of temperature, not just highs or lows. "If you're talking heat waves, that nighttime low is incredibly important for determining total heat stress," [said meteorologist Jeff Masters of Yale Climate Connections]. "So if it doesn't cool off at night, your body doesn't have time to readjust to all the heat." As nighttime temperatures increase, more people die and lose sleep, studies show. The years 2021 and 1936 tie for America's hottest summer, which is June through August. Through July, 2026 is a shade cooler than 2021, which was powered by record heat in June. Because of climate change, Masters said, "this may be one of the coolest years we're gonna experience for the rest of our lives." What's needed, Masters said, is "to stop burning so many fossil fuels. We also need to be spending money to adapt to the new climate that we've put in place."

Paper Goods Company Is Investigating an Alternative to Trees

8 août 2026 à 18:34
The Dallas Business Journal reported Monday that the U.S. multinational paper goods company Kimberly-Clark announced "that its researchers identified and advanced patented technology transforming fibers from hesperaloe, a low-water-use plant with pointy leaves that thrives in the southwest region of the country, into material for paper towels." Discovering an alternative to conventional wood fiber "could reshape how the company, and the industry at large, manufactures products," according to article. And the move comes "amid growing pressure on manufacturers regarding their reliance on wood fibre from freshly felled trees," reports The Telegraph. "Campaigners claim that more than one million trees are cut down every day..." Unlike trees, hesperaloe can be grown on dry, low-quality farmland unsuitable for most food crops and harvested much more quickly. Kimberly-Clark said it had tested more than 70 potential materials before settling on hesperaloe. Earlier candidates included wheat straw, corn waste, seaweed, algae and chicken feathers. The US consumer goods giant will now develop the fibre at a pilot factory in Yuma, Arizona, working with local growers to determine whether the crop can be cultivated for commercial use in its tissue products. "This represents an exciting moonshot for Kimberly-Clark and the culmination of more than two decades of materials and plant science expertise," said Craig Slavtcheff, who is helping develop the new toilet paper. However, the company said products made from hesperaloe remained years away from supermarket shelves, with further research needed before the fibre could be produced at the scale required for global manufacturing. The US-based company has invested about $250m (£190m) in the project and filed more than 30 patents linked to the technology.

Radical Study Suggests Life on Earth Arose Twice

Par : BeauHD
7 août 2026 à 11:00
A new study argues that life may have emerged twice on Earth. "Two of the main lineages of life -- bacteria and archaea -- may have independently figured out the secrets of metabolism that upgraded them from non-living to living," reports ScienceAlert, citing a new study that "focused on the most rudimentary set of chemical reactions thought to enable this transformation." From the report: "The surprise is that the enzymes that catalyze those reactions are not conserved across the evolutionary divide that separates bacteria and archaea," says William Martin, a biologist at Heinrich Heine University Dusseldorf in Germany. "The new data leave only one conclusion. The bacterial and archaeal lineages made the transition to the free-living state independently. Only free-living cells are alive. "Let's call it by name: we are looking at one origin of the genetic code, but two origins of life." That's a huge claim to make, especially when defining what life even is can be surprisingly tricky. The findings have been published in the journal Science Advances.

South Korea Records Its Highest Ever Temperature

3 août 2026 à 16:00
South Korea recorded its highest temperature since modern observations began in 1904, with the city of Yangsan reaching 42.5C as temperatures exceeded 40C for a fifth consecutive day. Authorities warned residents to "immediately stop all outdoor activities." The Guardian reports: More than 20 localities in South Korea were under emergency heatwave alerts on Sunday -- a new warning category introduced this year to better address rising temperatures. An emergency alert is issued when areas experiencing a heatwave are forecast to hit perceived temperatures of 38C or an actual temperature of 39C for the day. Issuing a heat warning, the weather agency urged people to "immediately stop all outdoor activities," adding that "indoor spaces without air conditioning are dangerous." "Move immediately to a cool place, such as a designated cooling centre or a shaded area, and stay hydrated while resting," it advised. Fearing for those people most vulnerable to heat, the prime minister, Han Seong-sook, ordered local officials to strengthen safety checks on residents and to ensure a stable power and water supply was maintained. [...] Korea Meteorological Administration (KMA) data show the average annual number of heatwave days in the country has more than doubled to 19 in the past five years.

The U.S. company Meteomatics has created an automated weather-monitoring system that uses drones to collect atmospheric data at multiple altitudes before returning to recharge and upload their findings. The so-called Meteobase, which consists of a base station on the ground with a drone that can be launched and recovered automatically, "is highly weather resistant and keeps the drone at a comfortable temperature," reports The Guardian. "It can send out one data-gathering mission a day, or multiple flights to monitor fog, icing, an advancing weather front, or other fast-changing conditions." The report says the reusable drones could offer a cheaper, more controllable alternative to helium weather balloons, especially for tracking rapidly changing conditions.

Earth's Biggest Disasters Strike In a Hidden Pattern Every 27 Million Years

Par : BeauHD
28 juillet 2026 à 07:00
A new analysis of 89 major geological events over the past 260 million years found evidence that mass extinctions, volcanic eruptions, ocean crises, and other upheavals may cluster around a roughly 27.5-million-year cycle. The cause remains unknown, with possibilities ranging from mantle activity and orbital changes to speculative galactic influences. Slashdot reader alternative_right shares a report from ScienceAlert: One possibility lies deep within Earth itself. The planet's mantle is constantly circulating through convection, albeit at an almost unimaginably slow pace. Periodic changes in mantle convection, or the initiation of mantle plumes, could influence volcanism, plate tectonics, mountain building, and other large-scale geological processes. Because these systems are closely interconnected, disturbances originating deep within Earth could eventually ripple through the planet's surface, oceans, climate, and biosphere. Another hypothesis focuses on interactions between Earth's surface and interior. Long-term orbital variations influence climate and sea level, periodically redistributing enormous amounts of water, ice, and sediment across the planet. [New York University geologist Michael Rampino] discusses the possibility that these changing surface loads subtly modify stresses within Earth's crust and upper mantle, potentially influencing tectonic and volcanic activity over geological timescales. Rampino also considers possible influences beyond Earth, an idea he has been weighing up since the 1980s. As the Solar System orbits the center of the Milky Way, it oscillates above and below the galaxy's mid-plane, with the timing of these passages aligning with that of Earth's major upheavals. These crossings, other researchers have suggested, could also gravitationally perturb comets in the distant Oort Cloud, increasing the likelihood of large asteroid impacts. Another, even more speculative, hypothesis suggests that if dark matter is concentrated near the galactic plane, a fraction of it could occasionally be captured by Earth. Over millions of years, this process could generate small amounts of internal heat, potentially influencing geological activity. At present, however, there is no direct evidence supporting either mechanism, so they remain very controversial. Large asteroid impacts are discussed separately in the paper. Although they were not included in the statistical analysis of the 89 geological events, the timing of several of Earth's largest known impact craters appears broadly consistent with the proposed 27.5-million-year rhythm, as Rampino has discussed in earlier papers. Rampino suggests this correspondence may warrant further investigation, but stops short of claiming a causal relationship.

Wildfires, Evacuations, and Smoke Hit Europe and North America

26 juillet 2026 à 18:39
270,000 people have been displaced by wildfires in France and Spain, reports the Guardian. A wildfire even forced evacuations in Scotland. And wildfires "have now scorched four million acres of land in the U.S.," reports NPR, as tens of millions of people in North America "are continuing to endure hazardous smoke from out of control wildfires burning across Canada and the Western U.S." At America's National Interagency Fire Center, NPR's wildfire correspondent says all of America's firefighting resources have now been deployed across the country. "So if we get another big fire, we're in trouble... International aid could be harder to come by if the situation in Southern Europe gets worse and firefighters are going to be needed there." Meanwhile Toronto was blanketed this week "with eye-watering, cough-inducing soot," writes a climate-change reporter for the Toronto Star newspaper, "briefly giving us the worst air quality in the world." But looking to the future after a wildfire that's 50% larger than any in Ontario's history (315,000 hectares or 778,331 acres), he had this to say about the eye-watering smoke. "It will be back." The article's headline warned of "Our smoke-filled future" and how Canada "must prepare for bigger wildfires, every summer — forever." Even if global carbon emissions were cut dramatically, so long as any greenhouse gases are being put into the atmosphere, climate scientists say the world will continue to get hotter. And as the temperature rises, the forests dry out and the wildfires will get bigger, stronger and more frequent. "It's not going to get better. It's going to get worse," said Edward Struzik, a fellow with the Institute for Energy and Environmental Policy at Queen's University and the author of Dark Days at Noon: the Future of Fire . "These fires aren't going away. Toronto is going to get smoke every summer...." The best solution would have been to dramatically cut emissions years ago. The harsh scientific reality is there's nothing we can do to stop wildfire smoke from blanketing cities for a few days every summer — and it's going to continue for decades to come. We're all going to need to buy air purifiers and masks and get used to it.... "The idea that we can thin our way through the boreal forest boggles the mind," [says Zeke Hausfather, a climate scientist at Berkeley Earth, an independent non-profit research organization]. "There aren't enough people in Canada to do that." The boreal forest in Canada is an enormous and largely roadless expanse bigger than the entire European Union. In comparison, America's much smaller forests are criss-crossed by roads, making firefighter access much quicker and easier. And the nature of the forests is fundamentally different as well, said Hausfather, who wrote an article summarizing research on the subject. "Western U.S. forests have evolved for frequent low-level fires that burn out the undergrowth — usually every five to 30 years," he said. "Historically, before fire suppression, fires would burn through, and they wouldn't actually kill the trees. They'd just kill smaller trees and clear out the brush." "The boreal forest is a fundamentally different beast," he said. "It's an ecosystem designed to burn." With smaller, more densely packed trees, the boreal is wetter and colder and doesn't burn anywhere near as often — every 100 to 200 years on average, Hausfather said. But when fire does erupt, it's often much more intense, burning up into the canopy and levelling everything in its path... Clearing out the dead wood on the ground wouldn't prevent, or even slow, the canopy fires that sweep the boreal, said Hausfather.

Drying Lakebeds Are Releasing Massive Amounts of Carbon, Study Finds

25 juillet 2026 à 22:00
"In many parts of the world, lakes are drying out at a scale so massive that scientists are warning they may be emitting enough greenhouse gases to rival our fossil fuel habit," reports ScienceAlert: In a new study published in Science, scientists say the Aral Sea — the world's largest desiccated lake — has emitted a whopping 204 megatons (~225 million US tons) of carbon dioxide since it was drained in the 1960s... The study estimates that between 1960 and 2022, the evaporating sea has released 204 megatons of carbon dioxide into the atmosphere, based on site surveys and core samples collected from across the dry lakebed... The new study suggests that rehydrating the entire basin could come with enormous benefits to the environment, not just within the sea itself, but at a global level. "There is a hidden carbon treasure beneath the Aral Sea," says biochemist Rafael Marcé from the Spanish National Research Council. "If these sediments remain exposed, carbon will continue to be released into the atmosphere. If the sea is re-flooded, that same carbon could shift from being a source of emissions to becoming part of the climate solution." According to the researchers' calculations, re-flooding the lakebed could prevent the release of the estimated 165 megatons of carbon that remain. The study also revealed that nearly one-fifth of the Aral Sea's carbon emissions are actually being released as wind blows away sediment on the lakebed, a factor that researchers had not accounted for in the past.

Longtime Slashdot reader BeaverCleaver shares a report from the BBC: The wreckage of a Pan American Airways plane has been found 74 years after it plunged into the Atlantic Ocean in a crash that prompted mandatory airline safety briefings. The Clipper Endeavor was found 2,000ft (610m) below sea level off the coast of Puerto Rico with a sonar-equipped drone. It went down on April 11, 1952, following multiple-engine failure shortly after take-off. Everyone onboard survived the impact -- but passengers struggled to locate life vests and rafts as the plane rapidly sank. Of the 69 passengers and crew onboard, just 17 survived. The disaster led to sweeping reforms in aviation safety, including compulsory pre-flight safety briefings on every commercial flight. [...] Today, before every commercial flight, cabin crew are required to outline where a plane's exits are, as well as the location of life vests and how to inflate them.

Long Presumed Dead, a Thriving Coral Reef Is Discovered in West Africa

Par : BeauHD
22 juillet 2026 à 11:00
Scientists have rediscovered a healthy coral reef off the coast of Benin more than 60 years after surveyors first hinted at its existence. "At least eight coral types and eight fish species have formed a thriving ecosystem on this long-forgotten site," reports Inside Climate News. "What they had captured was a wealth of marine life: six types of soft coral; two black corals; and eight species of sheltering fish, from golden African snappers to the Monrovia doctorfish." From the report: While no coral samples have yet been extracted, researchers have classified the site as a mesophotic coral ecosystem (MCE). Such systems are light-dependent communities existing at the lower limits of reef-building corals. At more than 175 feet below the surface, the coral garden they discovered appears patchily scattered on a rocky substrate. Bridging the gap between shallow reefs and deeper benthic habitats, MCEs are home to distinct species and unique environmental conditions. While scientists are increasingly recognizing their ecological and climatic importance, they remain among the least explored elements of tropical and subtropical marine biodiversity. And this one has real potential to unlock new information about coral history. "Since it's an undisturbed marine ecosystem, it can help through carbon dating or paleoclimatic study to tell us which kind of climate system has occurred here in the past," said [Gerard Zinzindohoue, the project lead for Coral Reefs Rediscovering & Exploration in Benin]. "It's better to know the past to help explain the present, and help know which kind of direction we can take in the future." In addition to the blackbar soldierfish, West African goatfish, and Guinean angelfish filmed darting through the reef, the discovery presents potential conservation claims for other marine life. "We will be advocating for its full protection, perhaps by setting up a marine protected area around it," said [Houangninan Midinoudewa, an oceanographic researcher at the Benin Marine Conservation Club], who specializes in elasmobranchs -- the study of sharks, rays, and skates. Midinoudewa is currently submitting an application to designate the area as an Important Shark and Ray Area with the International Union for Conservation of Nature. Based on the knowledge of local fishermen, Midinoudewa is confident the reef is home to sawback angel sharks, silky sharks, brown skates, and marbled stingrays. The team behind the discovery hopes this will spark a wave of similar discoveries in the waters off West Africa, an area of the world underserved by scientific research projects. "I hope the Gulf of Guinea will be a hub for research because we know our resources are being exploited and people [need to] know exactly what we have and why we should care," said Midinoudewa. Zinzindohoue agrees: "We don't need to wait for others to come to our country to show us what is under our sea. We are the ones who must take responsibility."

California's 'Truth in Recycling' Law Blocked by Judge

19 juillet 2026 à 21:04
An anonymous reader shared this report from the Los Angeles Times: A federal judge has halted California's groundbreaking "Truth in Recycling" law, which aims to reduce consumer confusion about which packaging can be recycled. [Originally planned to take effect October 4th], California's recyclable packaging law prohibits manufacturers from using a "chasing arrows" recycling symbol on products or materials unless they are actually being recycled in a meaningful way, which the law quantifies... A coalition of farming, forestry, restaurant and packaging organizations sued the state in March, arguing the law violates their right to free speech. They argued that Senate Bill 343 operates as "government-imposed censorship." Judge William Hayes agreed that their challenge has merit, and on Tuesday ordered California Atty. Gen. Rob Bonta, the defendant in the case, to pause enforcement of the law "until further order of the Court...." Advocates of reducing plastic use disagreed. "The court got it wrong, and I'm confident that the state will ultimately prevail," said Nick Lapis, director of advocacy for Californians Against Waste. "S.B. 343 does not violate the 1st Amendment; it requires companies to tell the truth when they make recyclability claims. Suggesting that the 1st Amendment protects misleading environmental marketing is inconsistent with the basic principles of consumer protection that states like California have implemented for decades." In January, CalRecycle, the state's waste agency, reported that less than 10% of most single-use plastic materials in the state were being recycled. Even yogurt containers and margarine tubs — made of ubiquitous polypropylene, or No. 5 plastic — are being recycled at a rate of only 2% in the state, the report said. Only 5% of colored shampoo and detergent bottles, made from polyethylene, or No. 1 plastic, are getting recycled... Plastic materials that can't be recycled are typically sent to landfills or sometimes illegally shipped overseas, where they are burned or end up in landfills, rivers and waterways. The bill's author told the Los Angeles Times "All you have to do is look at the numbers. These products are not getting recycled, despite what the industry is claiming. They are just confusing consumers, clogging the waste stream, polluting the environment, leading to higher and higher prices for local governments and ratepayers." He argues the symbols shouldn't be used to "confuse people who see the symbols [on products] and assume they can be recycled." The article also quotes Judith Enck, former Environmental Protection Agency regional administrator and president of the nonprofit Beyond Plastics. "Given the long history of the plastics industry deceiving the public about plastics recycling, this is an especially bad outcome. It is a reminder that the plastics industry has enough money to fight even the most modest policy designed to protect people and the planet."

Google-Backed Satellites For Wildfire Detection Launch As Smoke Chokes US, Canada

Par : BeauHD
18 juillet 2026 à 11:00
An anonymous reader quotes a report from Ars Technica: As smoke from hundreds of burning wildfires spread across Canada and the United States, the first three operational satellites in the Google-backed FireSat program successfully launched into orbit. The satellites will begin providing wildfire detection capable of spotting even small fires in the United States, Australia, and Europe before the end of the year. The launch of the microsatellites aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California on July 7, 2026 marks a transition to "initial operational capability" for the FireSat constellation managed by the nonprofit Earth Fire Alliance. After a three-month testing period, the three satellites will begin actively providing data to fire agencies while covering every fire-prone region on Earth at least twice per day. FireSat represents the first satellite constellation purpose-built for detecting wildfires, including spotting smaller fires that other satellites may miss. The satellites were designed by California-based satellite manufacturer Muon Space and have received over $15 million from Google to support initial deployment. Other notable financial supporters include the Bezos Earth Fund that committed $26 million. Each satellite is equipped with multispectral imaging that can peer through smoke and clouds and detect fires as small as five by five meters -- about 16 by 16 feet. That capability was proven by a FireSat Protoflight satellite that launched in March 2025 and collected more than one million images, while showing it could detect low-intensity blazes invisible to existing satellites. The "early adopter" organizations that will start using FireSat data this year include fire agencies in California, Colorado, Australia, and Portugal. As more satellites launch, the FireSat program aims to provide the latest imagery anywhere in the world on an hourly basis by 2029. Such imagery would eventually become available every 20 minutes once the full constellation of more than 50 satellites is launched by the early 2030s. Detection of small wildfires before they burn out of control could prove extremely helpful. The Earth Fire Alliance has projected that even an hourly revisit rate by the FireSat constellation could help save more than $1 billion in fire damage costs and prevent nearly 22 million tons of carbon emissions, along with protecting 3,500 homes and 1.3 million acres of land. To assist with that capability, Google Research plans to use the company's AI models to compare operational FireSat data with historical images in order to accurately identify very small fires and to inform predictive modeling of wildfires. Google celebrated the launch of the first operational FireSat satellites by describing the event as "another tangible step forward in putting practical AI to work for climate resilience."
