The Push to Make U.S. College Students Climate Literate

Students and professors at universities across the country are pushing for general education requirements to equip students to combat climate change.

The majority of people in the United States want the government to do more to address climate change, according to a 2020 study by the Pew Research Center, yet few of them can be counted as “climate literate”—which the North American Association for Environmental Education defines through metrics such as being able to understand essential climate principles, assess the credibility of climate information, and make “informed and responsible decisions” where their actions may impact the climate. The purpose of being climate literate is not just to gain scientific knowledge, but to uncover climate perspectives and solutions that can inspire action. In 2023, Allianz surveyed Americans to see how climate literate they were, asking scientific questions like “What is the impact of the rise in temperature?” as well as political ones like “What is COP?”, referring to the annual Conference of the Parties meetings that broadly discuss climate action among U.N. member nations. Researchers found only five percent of Americans had a high level of climate literacy.  To close this gap in climate literacy, a burgeoning movement of students and professors is pushing for climate literacy to be integrated in general education. Some efforts have already succeeded, such as at the University of California, San Diego, which in 2024 became one of the first universities to require that all undergraduates complete a general education course related to climate change. The push to implement this requirement was the result of a student-faculty alliance that has been organizing toward “climate education for all” since 2021. Arizona State University also revamped its general education requirements in 2024, making a three-credit sustainability course mandatory for incoming students. The University of Massachusetts Amherst has a robust climate literacy program, though the university has not yet included this in its required coursework.  UC San Diego’s victory recently inspired a group of thirteen professors at the University of California, Davis, to propose a Climate Crisis General Education requirement for undergraduate students. Former UC Davis undergraduate students Chely Saens, Meghan Van Note, and Trisha Trilokekar wrote that since “climate issues affect all fields of study, the new study requirement would ensure that every student, regardless of their major, gains a broad understanding of climate science, justice, and solutions.” The proposal has collected at least 530 endorsements from various student and staff groups across campus. Should they succeed in implementing it, a graduating class in the near future would be required to learn about sanitation, clean energy, sustainable communities, and responsible consumption and production. Most of the proposed courses for the climate change requirement would overlap with existing general education requirements. Mark Huising, who teaches neurobiology and physiology at UC Davis’s College of Biological Sciences, was part of the group pushing for this general education requirement. “It’s part of our core mission as faculty—especially of higher learning—to make sure that the teachings that we do are broadly applicable and useful to the students that we teach,” he tells The Progressive.  Huising says he saw the stakes of integrating climate education into undergraduate studies in 2018, when a student in the front row of one of his courses raised their hand and to be excused, having just found out their home had burned down in the Camp Fire. It pushed Huising to think more deeply about how to teach at a time when many students (and faculty members) are impacted by climate disasters. He continuously sees students dealing with environmental issues that interfere with their education. “Air quality concerns are front of mind,” Huising says. “More regularly we have people in our community who are facing extreme heat in combination with housing instability.” He says the group who worked on the general education proposal wanted to make sure the required course didn’t just focus on the scientific elements of climate change, but also “the human connection,” including perspectives on climate justice and solutions that intertwine with coursework in urban planning, public policy, renewable energy, public health, law, ecology, politics, sociology, and journalism. This, he says, instills a “sense of urgency” and agency in creating a graduated workforce “ who knows how to navigate this information landscape around climate change.”  But the proposal is currently a standstill. ​​ Earlier this fall, the Academic Senate at UC Davis, the faculty governance system, declined to implement the proposal, citing logistical issues such as concerns about the school’s capacity to implement a new general education curriculum on a campus with more than 30,000 undergraduates. “ We can’t create a requirement for students and then set them up to not be able to take classes that they need, or increase their time to [earn their] degree,” Huising says. Still, he says, the proposal’s proponents believe they can address these concerns with a carefully planned curriculum rollout, and are currently working to address the concerns and bring the amended proposal back to the Academic Senate.  Huising and his colleagues have brainstormed ways to broaden the range of courses that could fulfill the requirement by enriching courses in the current curriculum with climate-focused lessons. For him, this means teaching his physiology students about the impacts of extreme heat on the human body. Similarly, one of his colleagues in the Department of Entomology and Nematology is incorporating lessons on how Indigenous land use and water management practices can control insect populations in wetlands in the Central Valley. The English department, meanwhile, is adding literature courses focused on climate issues to its course catalog. At Harvey Mudd College, a private liberal arts school in Southern California focused on science, technology, engineering, and math (STEM), chemistry and climate professor Leila Hawkins hopes to create a permanent climate-focused general education course. A current class called “STEM & Social Impact” is temporarily focused on climate change until next spring. “The question is, do we keep it on climate or do we do something else like [artificial intelligence] or other big sticky problems?” Hawkins says. The course is currently taught by an interdisciplinary group of seven professors, including Hawkins, who teaches basic earth science principles for the class. Three of the course teachers are humanities, social sciences, or arts faculty, while other four are STEM faculty. Hawkins says it’s important for the climate change requirement to have a permanent place in curriculum, given the implications of global climate change for her students’ futures, “and the fact that we have to vote for people who are going to weigh in on policy choices related to climate and energy and resilience and planning and adaptation.” If students are not adequately informed about what climate change is and what can be done about it, she says, “they’re going to be much less able to be productive participants in a functioning society that’s going to tackle this.” An established requirement should have some basic earth science content, Hawkins says, but also an equal measure of historical context around climate policies. “You cannot avoid the partisan climate conversation,” she says. “I think having a really open, productive conversation about how it has become such a divided issue is really important.”  Similar to UC Davis’s proposal, Hawkins says a focus on climate solutions is essential in these courses, because without it, “it’s depressing to some students to the point of being immobilizing or debilitating.” Solutions-focused learning gives a vast array of students an opportunity to understand how they could play a role in the solution space given their own strengths and abilities. “They might want to be an artist or an engineer or a computer scientist or a historian or a tradesman—or whatever they want to be,” Hawkins says, “but there’s going to be a way that they can work on a solution for climate if they want to with those skills and interests.” At the end of the day, Huising says there is “not a large ideological opposition to doing this, but people are very comfortable not making a change in how we do stuff . . . . And very importantly, when we survey our students and when we talk to our student leadership on campus, there’s widespread support for this,” Huising notes.

MIT community in 2025: A year in review

Top stories highlighted the Institute’s leading positions in world and national rankings; new collaboratives tackling manufacturing, generative AI, and quantum; how one professor influenced hundreds of thousands of students around the world; and more.

In 2025, MIT maintained its standard of community and research excellence amidst a shift in national priorities regarding the federal funding of higher education. Notably, QS ranked MIT No. 1 in the world for the 14th straight year, while U.S. News ranked MIT No. 2 in the nation for the 5th straight year.This year, President Sally Kornbluth also added to the Institute’s slate of community-wide strategic initiatives, with new collaborative efforts focused on manufacturing, generative artificial intelligence, and quantum science and engineering. In addition, MIT opened several new buildings and spaces, hosted a campuswide art festival, and continued its tradition of bringing the latest in science and technology to the local community and to the world. Here are some of the top stories from around MIT over the past 12 months.MIT collaborativesPresident Kornbluth announced three new Institute-wide collaborative efforts designed to foster and support alliances that will take on global problems. The Initiative for New Manufacturing (INM) will work toward bolstering industry and creating jobs by driving innovation across vital manufacturing sectors. The MIT Generative AI Impact Consortium (MGAIC), a group of industry leaders and MIT researchers, aims to harness the power of generative artificial intelligence for the good of society. And the MIT Quantum Initiative (QMIT) will leverage quantum breakthroughs to drive the future of scientific and technological progress.These missions join three announced last year — the Climate Project at MIT, the MIT Human Insight Collaborative (MITHIC), and the MIT Health and Life Sciences Collaborative (MIT HEALS).Sharing the wonders of science and technologyThis year saw the launch of MIT Learn, a dynamic AI-enabled website that hosts nearly 13,000 non-degree learning opportunities, making it easier for learners around the world to discover the courses and resources available on MIT’s various learning platforms.The Institute also hosted the Cambridge Science Carnival, a hands-on event managed by the MIT Museum that drew approximately 20,000 attendees and featured more than 140 activities, demonstrations, and installations tied to the topics of science, technology, engineering, arts, and mathematics (STEAM).CommencementAt Commencement, Hank Green urged MIT’s newest graduates to focus their work on the “everyday solvable problems of normal people,” even if it is not always the easiest or most obvious course of action. Green is a popular content creator and YouTuber whose work often focuses on science and STEAM issues, and who co-created the educational media company Complexly.President Kornbluth challenged graduates to be “ambassadors” for the open-minded inquiry and collaborative work that marks everyday life at MIT.Top accoladesIn January, the White House bestowed national medals of science and technology — the country’s highest awards for scientists and engineers — on four MIT professors and an additional alumnus. Moderna, with deep MIT roots, was also recognized.As in past years, MIT faculty, staff, and alumni were honored with election to the various national academies: the National Academy of Sciences, the National Academy of Engineering, the National Academy of Medicine, and the National Academy of Inventors.Faculty member Carlo Ratti served as curator of the Venice Biennale’s 19th International Architecture Exhibition.Members of MIT Video Productions won a New England Emmy Award for their short film on the art and science of hand-forged knives with master bladesmith Bob Kramer.And at MIT, Dimitris Bertsimas, vice provost for open learning and a professor of operations research, won this year’s Killian Award, the Institute’s highest faculty honor.New and refreshed spacesIn the heart of campus, the Edward and Joyce Linde Music Building became fully operational to start off the year. In celebration, the Institute hosted Artfinity, a vibrant multiweek exploration of art and ideas, with more than 80 free performing and visual arts events including a film festival, interactive augmented-reality art installations, a simulated lunar landing, and concerts by both student groups and internationally renowned musicians.Over the summer, the “Outfinite” — the open space connecting Hockfield Court with Massachusetts Avenue — was officially named the L. Rafael Reif Innovation Corridor in honor of President Emeritus L. Rafael Reif, MIT’s 17th president.And in October, the Undergraduate Advising Center’s bright new home opened in Building 11 along the Infinite Corridor, bringing a welcoming and functional destination for MIT undergraduate students within the Institute’s Main Group.Student honors and awardsMIT undergraduates earned an impressive number of prestigious awards in 2025. Exceptional students were honored with Rhodes, Gates Cambridge, and Schwarzman scholarships, among others.A number of MIT student-athletes also helped to secure their team’s first NCAA national championship in Institute history: Women’s track and field won both the indoor national championship and outdoor national championship, while women’s swimming and diving won their national title as well.Also for the fifth year in a row, MIT students earned all five top spots at the Putnam Mathematical Competition.Leadership transitionsSeveral senior administrative leaders took on new roles in 2025. Anantha Chandrakasan was named provost; Paula Hammond was named dean of the School of Engineering; Richard Locke was named dean of the MIT Sloan School of Management; Gaspare LoDuca was named vice president for information systems and technology and CIO; Evelyn Wang was named vice president for energy and climate; and David Darmofal was named vice chancellor for undergraduate and graduate education.Additional new leadership transitions include: Ana Bakshi was named executive director of the Martin Trust Center for MIT Entrepreneurship; Fikile Brushett was named director of the David H. Koch School of Chemical Engineering Practice; Laurent Demanet was named co-director of the Center for Computational Science and Engineering; Rohit Karnik was named director of the Abdul Latif Jameel Water and Food Systems Lab; Usha Lee McFarling was named director of the Knight Science Journalism Program; C. Cem Tasan was named director of the Materials Research Laboratory; and Jessika Trancik was named director of the Sociotechnical Systems Research Center.Remembering those we lostAmong MIT community members who died this year were David Baltimore, Juanita Battle, Harvey Kent Bowen, Stanley Fischer, Frederick Greene, Lee Grodzins, John Joannopoulos, Keith Johnson, Daniel Kleppner, Earle Lomon, Nuno Loureiro, Victor K. McElheny, David Schmittlein, Anthony Sinskey, Peter Temin, Barry Vercoe, Rainer Weiss, Alan Whitney, and Ioannis Yannas.In case you missed it…Additional top stories from around the Institute in 2025 include a description of the environmental and sustainability implications of generative AI tech and applications; the story of how an MIT professor introduced hundreds of thousands of students to neuroscience with his classic textbook; a look at how MIT entrepreneurs are using AI; a roundup of new books by MIT faculty and staff; and behind the scenes with MIT students who cracked a longstanding egg dilemma.

12 Environmental Commentaries That Defined Our Year in 2025

These expert opinions address opportunities to make a difference — and point out a few of our failures. The post 12 Environmental Commentaries That Defined Our Year in 2025 appeared first on The Revelator.

Some of my favorite emails contain variations on an exciting phrase: “I’ve enclosed an op-ed for your consideration.” These messages — and their accompanying commentaries — come to us from environmental experts all over the world who have something important to say about saving life on this big blue marble we call home. Some of them offer roadmaps for improving our efforts to address problems like conservation, environmental injustice, or climate change. Others point out lesser-known threats we should do more to address. Many authors share personal insights and experiences that most readers would otherwise rarely encounter. Here are 12 of our favorite environmental commentaries of the past year, addressing Indigenous rights, coral reefs, activism, some iconic or lesser-known endangered species, and more: ‘Active Management’ Harms Forests — And It’s About to Get a Whole Lot Worse Birding’s Tragic Blind Spot Ghost Reefs of 2083: The Paleontology of Color (A Speculative ‘Fiction’) The Last Breath of the Himalayas: Can We Stop the Collapse? Nature Is ‘Not for Sale’ Palm Oil Continues to Plague Borneo’s Orangutans, Elephants, and Other Icons Rare Earth Metals Must Not Come at the Cost of Indigenous Rights Saving America’s National Parks and Forests Means Shaking Off the Rust of Inaction Saving the Ryukyu Rabbit Tick: The Posterchild of Parasite Conservation Trump’s Approach to Public Lands? Expanding the Extractive Economy and Declaring a War on Nature What Catastrophes Get Our Attention and Why It Matters Who Heals the Earth’s Healers? Ways to Avert Burnout for Environmental Advocates Truthfully, this list could have been twice as long — and it still wouldn’t have included every inspirational or intriguing expert opinion we published in 2025. I encourage you to scroll through our entire Ideas category, where you’ll find a few dozen more essays worth reading. (While you’re at it, keep going back into 2024 or earlier — most of our commentaries have a long shelf life and remain of interest for quite a while after they’re published.) Meanwhile, don’t forget that a different kind of commentary appears a couple of times a month in our newsletter: exclusive cartoons by Tom Toro. Here’s one of my favorites from the past year: Do you have a story to tell in the year ahead? We’re always open to op-eds and commentaries from activists, scientists, conservationists, legislators, government employees, and others — especially anyone with insight about the regressive and repressive second Trump administration.

"Year of octopus" declared after warmer seas leads to record numbers

The Wildlife Trusts say its is "flabbergasted" by the sighting of the highest number of octopuses since 1950

"Year of octopus" declared after warmer seas leads to record numbersJonah FisherEnvironment correspondentWatch: Octopuses filmed by divers off the coast of Cornwall this yearA wildlife charity has declared 2025 "the Year of the Blooming Octopus" after record numbers were spotted off the south-west coast of England.In its annual marine review the Wildlife Trusts says octopus numbers were this summer at their highest level since 1950.Warmer winters, which are linked to climate change, are thought to be responsible for the population spike, which is known as a "bloom".The charity's findings are backed up by official figures which show that more than 1,200 tonnes of octopus was caught by fishermen in UK waters in the summer of 2025. The Wildlife Trusts/Kirsty AndrewsThe Wildlife Trusts says the highest number of octopuses has been seen off the south coast of Devon and Cornwall since 1950. It's a dramatic increase on previous years. Only once since 2021 has more than 200 tonnes of octopus been landed.Experts say most of those spotted are Octopus vulgaris a species commonly seen in the warmer Mediterranean Sea. Wildlife Trusts volunteers in Cornwall and Devon reported an increase in sightings of more than 1,500 percent on 2023 figures along one stretch of the south coast. "It really has been exceptional," says Matt Slater from the Cornwall Wildlife Trust. "We've seen octopuses jet-propelling themselves along. We've seen octopuses camouflaging themselves, they look just like seaweeds. "We've seen them cleaning themselves. And we've even seen them walking, using two legs just to nonchalantly cruise away from the diver underwater."It's unclear at this point whether the rise in numbers is permanent or cyclical, which would mean octopus numbers returning to more typical levels after this year's bloom. The eight-armed cephalopods eat shellfish such as lobster, crabs and scallops so the Wildlife Trusts warn that if population numbers remain high, both fishing and eating habits may have to change."They are having an impact on those (shellfish) species around our shores. And as a consequence, they will be having an impact on our fishing industry who target those species as well," Ruth Williams the head of marine for The Wildlife Trusts told the BBC's Today programmme. "But there are opportunities and our fishing industry are doing some research into that at the moment to try and evolve with the changing fisheries that we're seeing as a result of climate change."Government data shows crab landings down on previous years but catches of lobster, crawfish and scallops stable.Wildlife Trusts of South and West Wales/Lynne NewtonA record number of puffins were recorded on Skomer Island in Pembrokeshire this year. Alongside good news for octopus lovers, the Wildlife Trusts' marine review contains more sobering news.The Trusts say this year was bookended by environmental disasters, with a collision between an oil tanker and a container ship in the North Sea in March spilling huge quantities of plastic resin pellets, and nearly 4.5 tonnes of bio-beads released from a water treatment plant in Sussex in November.There was some better news for wildlife elsewhere, with a record 46,000 puffins recorded on Skomer, Pembrokeshire, while the charismatic black and white bird has made a comeback on the Isle of Muck following conservation efforts by Ulster Wildlife Trust to remove invasive brown rats.

Brown bears in central Italy are becoming less aggressive

As Apennine brown bears learned to co-exist with humans in central Italy, they evolved to become smaller and less aggressive, according to a new DNA study. The post Brown bears in central Italy are becoming less aggressive first appeared on EarthSky.

According to a new study, Apennine brown bears have become less aggressive and smaller in size after a long history of close proximity to humans. Image via Marco Tersigni/ Wikipedia (CC BY 2.0). Brown bears in central Italy are becoming less aggressive For generations, brown bears in central Italy have adjusted their behavior to survive in a landscape increasingly dominated by humans. Now, an international team of researchers led by the University of Ferrara has revealed that living in close quarters with villages and human activity has led to genetic changes in the bears. They said on December 15, 2025, that the brown bears today are less aggressive and physically smaller than their ancestors. The DNA studies also show that this isolated and endangered population of bears has less diversity in its genetic makeup and higher rates of inbreeding. The scientists published their peer-reviewed study in the journal Molecular Biology and Evolution on December 15, 2025. The research focuses on Apennine brown bears (Ursus arctos marsicanus), which live exclusively in central Italy. Apennine brown bears shaped by history The Apennine brown bears form a small and isolated population with a long history of close proximity to human communities. Previous research indicates this population split from other European brown bears between 2,000 and 3,000 years ago. And it has remained isolated since Roman times. Over the centuries, human presence has had a direct impact on the habitat of these bears. The expansion of agriculture, forest clearing and the growth of settlements reduced and fragmented forests. This limited the available space for bears, affecting their ability to find food and reproduce. According to the authors, these landscape transformations were decisive in shaping the population’s history of isolation. Co-lead author Andrea Benazzo of the University of Ferrara said: One of the main factors driving isolation and decline was probably deforestation associated with the expansion of agriculture and increasing human density in central Italy. Apennine brown bears became isolated following human expansion. Consequently, their genetic diversity has reduced and rate of inbreeding has increased. Image via Bruno D’Amicis/ Molecular Biology and Evolution/ EurekAlert! A look at the bears’ DNA To understand how the bears changed over time, researchers analyzed their DNA: the set of genetic instructions that influence body development and certain behaviors. To do this, the team created a high-quality “reference genome” for the Apennine brown bear. It serves as a detailed map of its genetic material. Plus, it allows researchers to detect differences between individuals and populations. So scientists sequenced the DNA of several bears from this population and compared it with DNA from a much larger population of brown bears in Slovakia. They also compared the Italian bears’ DNA with previously published genomes from North American bears. This comparison made it possible to identify recent genetic changes and distinguish which traits are unique to Apennine brown bears. Genomic analyses show that – due to their isolation and small population size – Apennine brown bears exhibit high levels of inbreeding. Consequently, they have less genetic diversity, in contrast to other brown bear populations. Inbreeding occurs when related individuals reproduce with one another, a common situation in small and isolated populations. Unfortunately, inbreeding can increase the risk of health problems and reduce the ability to adapt to environmental changes. Human pressure as an adaptive force For generations, human presence in the Apennine forests exerted lethal pressure on the bear population. Larger and more aggressive individuals were more likely to come into conflict with people. So they were more frequently hunted or eliminated. Over time, this selective hunting drastically reduced the presence of such bears, favoring the survival and reproduction of smaller, less aggressive individuals. And so it resulted in a population with distinctive physical and behavioral traits. The study detected clear signs of selection in genes related to behavior, indicating that this systematic removal left a genetic imprint. According to co-lead author Giulia Fabbri of the University of Ferrara: The removal or displacement of more aggressive bears by humans likely drove the emergence of less conflict-prone individuals, reflecting how human interaction can shape the behavior of a species. Throughout their history, the larger, more aggressive bears were the targets of hunters. Thus, these bears evolved to be smaller and less aggressive. And over time, the Apennine bear population has exhibited distinctive physical and behavioral traits. Image via Mykola Pokalyuk/ Wikipedia (CC BY-SA 4.0). Conserving a genetically unique population The study shows human presence had contrasting effects on Apennine bears. On the one hand, human pressure favored traits that reduce conflict with people, such as less aggressive behavior and smaller body size. On the other hand, the population experienced a demographic decline and genetic erosion, increasing its vulnerability to extinction. The researchers emphasize that populations heavily affected by human activities still harbor unique genetic variants that deserve protection. Giorgio Bertorelle, professor of genetics at the University of Ferrara, explained: Even populations that have been strongly affected by human activities may harbor unique genetic variants that should be protected, for example by avoiding their dilution through the introduction of individuals from other regions. These genetic adaptations are valuable and should be taken into account when planning conservation strategies to preserve the population’s genetic identity. Apennine brown bears at risk of isolation and inbreeding At the same time, the population also faces risks stemming from its isolation and small size, particularly inbreeding. Reproduction between related individuals can increase the expression of harmful recessive genes. And that reduces the overall health and adaptive capacity in Apennine brown bears. In this sense, inbreeding is an important factor to consider when assessing the population’s long-term viability. However, the authors note that in populations that have remained small for long periods, some highly deleterious mutations might have been eliminated by natural selection, which does not remove the risk but does moderate its impact. This case illustrates one of the classic dilemmas of conservation biology: whether to intervene to increase genetic variability and reduce the risks of inbreeding, or to preserve a genetically singular population that has developed unique adaptations to its environment. Neither option is risk-free, and conservation decisions must balance long-term genetic health with the preservation of an irreplaceable evolutionary identity. Isolation increases inbreeding risk in Apennine brown bears, potentially reducing population health. This presents conservationists a difficult choice between genetic rescue and preserving a unique lineage. Image via Leonio/ Wikipedia (CC BY 3.0). Bottom line: As Apennine brown bears learned to co-exist with humans in central Italy, they evolved to become smaller and less aggressive, according to a new DNA study.

‘Unashamedly capitalist’ rewilders claim ‘Moneyball’ approach could make millions - but experts sceptical

Rich Stockdale says model of ‘regenerative capitalism’ would maximise profits by planting trees, restoring peatlands, and installing windfarms across its estatesThe founder of an investment firm buying large estates across Britain to restore woods and peatland has said it is “unashamedly and proudly” capitalist, and plans to make tens of millions of pounds in profit.Rich Stockdale, the chief executive of Oxygen Conservation, said his model of “regenerative capitalism” was a “force for good” because it would offer investors significant profits by planting trees, restoring peatlands, operating solar farms and holiday homes and installing new windfarms across its estates.

The founder of an investment firm buying large estates across Britain to restore woods and peatland has said it is “unashamedly and proudly” capitalist, and plans to make tens of millions of pounds in profit.Rich Stockdale, the chief executive of Oxygen Conservation, said his model of “regenerative capitalism” was a “force for good” because it would offer investors significant profits by planting trees, restoring peatlands, operating solar farms and holiday homes and installing new windfarms across its estates.The Exeter-based firm, which has bought 13 estates in under four years, plans to rapidly become the UK’s largest private landowner by expanding its current landholding of 50,000 acres (20,234 hectares) over the next five years to 250,000 acres.“We are applying a capitalist model, unashamedly and proudly,” Stockdale said, on a tour of Oxygen’s estate at Dorback near Grantown-on-Spey in the Cairngorms.“We think releasing, activating and motivating more capital into this space is the only way we can scale conservation for the better of climate, wildlife, people and everyone concerned.”He said Oxygen Conservation was creating a new market for “premium” carbon credits because some wealthy private and institutional investors would pay much higher prices to store carbon in new woodlands or peatland if they included high environmental and social benefit.Rich Stockdale, who runs Oxygen Conservation Photograph: Murdo MacLeod/The GuardianIts goal is to sell two million tonnes of carbon credits at well above the normal market rate, to prove that “regenerative capitalism” can work, he added.Stockdale likened his firm’s approach to the Brad Pitt movie Moneyball, in which a baseball coach used performance data to build a winning team. Oxygen Conservation uses Lidar laser scanning, thermal imaging to track deer and photogrammetry to build up 3D images of their estates.“We’ve taken very much a moneyball approach to the environment that’s previously been applied to sport. And that’s where you see all these threads that run through data, sport, high performance, US tech culture. We’ve brought that to the environmental world.”Campaigners and experts in natural capital who have been closely watching Oxygen Conservation’s rapid growth are sceptical about its methodology. They say it is based on significant levels of borrowing and speculative bets on the future value of its investments.Residents near Comrie in the Scottish Highlands, where Oxygen Conservation plans to build a large new 50MW windfarm, and around Dartmoor in south-west England where it bought a large hill farm, have accused the firm of ignoring local concerns and opposition.Josh Doble, the policy director at Community Land Scotland, a community-ownership advisory and campaign group, said Oxygen Conservation was the most bullish of a new generation of “mega lairds” accumulating extensive land-holdings.Their profit-driven approach “raised questions about the long-term commitment to restoring nature, rather than treating land as another investible commodity,” Doble said.“If absentee investor landowners own large parts of rural Britain, they must engage with the fact that owning land comes with responsibility. If you have a risky model, you need to be very careful because you’re not just making risky decisions in a boardroom, you’re playing with people’s lives.”Despite insisting Oxygen Conservation would be transparent about its plans and its business model, Stockdale refused to confirm or deny reports from natural capital experts he had already spent £150m and planned to spend another £100m on land.He said he could not say how much he paid the brewing firm BrewDog this summer for its estate at Kinrara near Kingussie or for Dorback because their owners had requested confidentiality.The Kinrara Estate which Oxygen Conservation. bought from BrewDog. Photograph: Murdo MacLeod/The GuardianCampaigners said withholding the sale price for a Highland estate is unusual, undermined transparency and risked concealing changes in the land market.Its biggest investors include Mike Dixon, a billionaire statistician who holds most of its shares, the self-styled ethical bank Triodos and Tony Bloom, a gambling billionaire who owns Brighton and Hove Albion FC. Bloom is currently being sued in a lawsuit alleging his gambling syndicate used “frontmen” to place bets. It is understood Bloom intends to file a defence to the claim.The latest accounts for its parent company, Oxygen House Group, which is also the majority shareholder in Low Carbon, the firm building its two Scottish windfarms, show the firm has two large bank loans totalling £106m to be repaid by 2033.Its critics point out that the two Scottish estates where it wants to build new 50MW windfarms, at Invergeldie near Loch Lomond and Trossachs national park, and at Blackburn and Hartsgarth estate near Langholm in the Borders, had bank loans worth £20.5m tied to them.Andrew Thompson, who helps run a local group opposing the windfarm, said residents feared those loans meant Oxygen Conservation had to push the windfarm through to pay off that debt, despite well-founded objections to the project from the conservation agency NatureScot and the national park authority. “Otherwise they’re completely screwed,” he said.A stream on the Kinrara Estate bought by Oxygen Conservation. Photograph: Murdo MacLeod/The GuardianStockdale claimed Oxygen’s investments are already worth more than £300m, and said its backers could see returns as high as 15% a year because the price of its carbon credits would climb to up to £180 a tonne and its biodiversity net gain credits were already worth £25,000 each.The average price for carbon in the UK last year was £37 a tonne. He said the appetite for premium credits had been proven when Burges Salmon, the law firm which acts for Oxygen Conservation, paid £125 a tonne earlier this year. The civil engineering firm Arup also paid £100 a tonne to a nature capital firm called Nattergal which owns rewilding estates in eastern England this year.He said one way to pay its investors was to sell off its estates after five years or so at a significant profit, with Oxygen Conservation remaining in charge of running the estate.He said wealthy investors including pension funds and international companies were willing to pay well above market rates for these credits, similar to some drivers preferring a Prius over a Ford. European investors were clamouring for Oxygen Conservation to invest on the continent.“We’re taking more risk, we’re pushing this out, we are doing things faster and different. I’ve been able to do that because of an incredible set of investors, an incredible team. Please don’t judge us by the norm, we aren’t trying to be,” Stockdale said.

2025 is ‘year of the octopus’ as record numbers spotted off England’s south coast

Milder weather led to a bloom in the invertebrates in south Cornwall and Devon, wildlife charity saysRecord numbers of sightings of one of the world’s most intelligent invertebrates over the summer have led the Wildlife Trusts to declare 2025 “the year of the octopus” in its annual review of Britain’s seas.A mild winter followed by an exceptionally warm spring prompted unprecedented numbers of Mediterranean octopuses to take up residence along England’s south coast, from Penzance in Cornwall to south Devon.

Record numbers of sightings of one of the world’s most intelligent invertebrates over the summer have led the Wildlife Trusts to declare 2025 “the year of the octopus” in its annual review of Britain’s seas.A mild winter followed by an exceptionally warm spring prompted unprecedented numbers of Mediterranean octopuses to take up residence along England’s south coast, from Penzance in Cornwall to south Devon.“The scale of the catch [recorded by local fishers] was of the order of about 13 times what we would normally expect in Cornish waters,” said Matt Slater, a marine conservation officer at Cornwall Wildlife Trust. “When we added up the numbers, approximately 233,000 octopuses were caught in UK waters this year – that’s a huge increase from what you would normally expect.”Octopus walking by Jenny KentThe common or Mediterranean octopus, Octopus vulgaris, is native to UK waters but ordinarily in such small numbers it is rarely seen. A sudden increase in the population – a bloom – is caused by a combination of a mild winter followed by a warm breeding season in the spring. The ideal conditions meant that more of the larvae of the common octopus were likely to survive, said Slater, possibly in part fuelled by the large numbers of spider crabs that have also been recorded along the south coast in recent years.The last time an octopus bloom of the size observed in 2025 was recorded was 1950, with records from the UK’s Marine Biological Association showing the last bloom recorded prior to that was in 1900.The huge numbers of octopuses along the south coast meant they could be easily spotted in shallow waters for the first time in recent history. Video footage from divers shows octopuses gathering in groups – they are usually solitary – as well as “walking” along the seabed on the tips of their limbs. One was even filmed grabbing at an underwater camera.“The first time I dived off the Lizard peninsula this year I saw five octopuses,” said Slater. “And these are big. There are two types of octopus in UK waters. There is the curled octopus, which is quite small, only getting to about the size of a football, but these common octopuses can be up to a metre and a half wide.”Another mild winter going into 2026 meant it was possible there could be a second bloom next year, said Slater, because historically, under these conditions, the blooms have repeated themselves for two consecutive years.Octopus grabbing a camera by Matthew Bradshaw“However, it is unlikely, based on past events, that it will go on for a long time,” he said. “But the sea keeps giving us surprises at the moment so it’s quite an unpredictable situation.”The Wildlife Trusts noted some of the other “surprises, successes and joyful moments” around the UK coastline included a record number of grey seals observed by the Cumbria Wildlife Trust, as well as record numbers of puffins on Skomer, an island off the coast of Wales famed for the birds.Other wildlife was recorded in unusual places. A volunteer with Shoresearch, the Wildlife Trusts’ national citizen science survey programme, recorded the first Capellinia fustifera sea slug in Yorkshire, a 12mm mollusc that resembles a gnarly root vegetable and is usually found in the south-west. In addition, a variable blenny, a Mediterranean fish, was discovered off the coast of Sussex for the first time. Populations had previously been limited to the West Country.A group of grey seals in South Walney, Cumbria. Photograph: Gemma de Gouveia/Wildlife TrustsNot everything was good news, though. “The year was bookended by environmental disasters,” said Ruth Williams, head of marine conservation at the Wildlife Trusts. “[There was] the North Sea tanker collision in March and in November the release of tonnes of biobeads off the Sussex coast. Our Wildlife Trusts staff and volunteers are making huge efforts to protect and restore our shorelines.”

The Water Came From Nowhere': Settlements, Hotels and Farms Flooded in Kenya’s Rift Valley

Dickson Ngome's farm at Lake Naivasha in Kenya's Rift Valley has been submerged due to rising water levels

NAIVASHA, Kenya (AP) — When Dickson Ngome first leased his farm at Lake Naivasha in Kenya’s Rift Valley in 2008, it was over 2 kilometers (1.2 miles) from shore. The farm was on 1.5 acres (0.6 hectares) of fertile land where he grew vegetables to sell at local markets.At the time, the lake was receding and people were worried that it might dry up altogether. But since 2011, the shore has crept ever closer. The rains started early this year, in September, and didn't let up for months.One morning in late October, Ngome and his family woke up to find their home and farm inside the lake. The lake levels had risen overnight and about a foot of water covered everything.“It seemed as if the lake was far from our homes,” Ngome’s wife, Rose Wafula, told The Associated Press. “And then one night we were shocked to find our houses flooded. The water came from nowhere.” Climate change caused increased rains, scientists say The couple and their four children have had to leave home and are camping out on the first floor of an abandoned school nearby.Some 5,000 people were displaced by the rise in Lake Naivasha’s levels this year. Some scientists attribute the higher levels to increased rains caused by climate change, although there may be other factors causing the lake’s steady rise over the past decade.The lake is a tourism hot spot and surrounded by farms, mostly growing flowers, which have gradually been disappearing into the water as the lake levels rise.Rising levels have not been isolated to Naivasha: Kenya’s Lake Baringo, Lake Nakuru and Lake Turkana — all in the Rift Valley — have been steadily rising for 15 years. “The lakes have risen almost beyond the highest level they have ever reached,” said Simon Onywere, who teaches environmental planning at Kenyatta University in Kenya’s capital Nairobi. Rising lake levels displaced tens of thousands A study in the Journal of Hydrology last year found that lake areas in East Africa increased by 71,822 square kilometers (27,730 square miles) between 2011 and 2023. That affects a lot of people: By 2021, more than 75,000 households had been displaced across the Rift Valley, according to a study commissioned that year by the Kenyan Environment Ministry and the United Nations Development Program.In Baringo, the submerged buildings that made headlines in 2020 and 2021 are still underwater.“In Lake Baringo, the water rose almost 14 meters,” Onywere said. “Everything went under, completely under. Buildings will never be seen again, like the Block Hotels of Lake Baringo.” Flower farms taking a beating Lake Naivasha has risen steadily too, “engulfing three quarters of some flower farms,” Onywere said.Horticulture is a major economic sector in Kenya, generating just over a billion U.S. dollars in revenue in 2024 and providing 40% of the volume of roses sold in the European Union, according to Kenya’s Ministry of Foreign Affairs.Significant research has gone into the reasons behind the rising lakes phenomenon: A 2021 study on the rise of Kenya’s Rift Valley lakes was coauthored by Kenyan meteorologist Richard Muita, who is now acting assistant director of the Kenya Meteorological Department.“There are researchers who come up with drivers that are geological, others with reasons like planetary factors,” Muita said. “The Kenya Meteorological Department found that the water level rises are associated with rainfall patterns and temperature changes. When the rains are plentiful, it aligns with the increase in the levels of the Rift Valley lake waters.”Sedimentation is also a factor. “From the research I have read, there’s a lot of sediment, especially from agricultural related activities, that flows into these lakes,” says Muita. ‘A mess’ made by the government years ago Naivasha’s official high water mark was demarcated at 1,892.8 meters (6,210 feet) above sea level by the Riparian Association in 1906, and is still used by surveyors today. That means this year’s flooding was still almost a meter (3 feet) below the high mark.It also means that the community of Kihoto on Lake Naivasha where the Ngomes lived lies on riparian land — land that falls below the high water mark, and can only be owned by the government.“It’s a mess established by the government … towards the late 1960s,” said Silas Wanjala, general manager of the Lake Naivasha Riparian Association, which was founded some 120 years ago and has been keeping meticulous records of the lake’s water levels since.Back then, a farmer was given a “temporary agricultural lease” on Kihoto, said Wanjala. When it later flooded and the farmer packed up and left, the farmworkers stayed on the land and later applied for subdivisions, which were approved. In the 60-odd years since, a whole settlement has grown on land that is officially not for lease or sale. This also isn’t the first time it’s been flooded, said Wanjala. It's just very rare that the water comes up this high. That’s little consolation for the people who have been displaced by this year’s floods and now cannot go home without risking confrontations with hippopotamuses.To support those people, the county is focusing its efforts on where the need is greatest.“We are tackling this as an emergency," says Joyce Ncece, chief officer for disaster management in Nakuru County, which oversees Lake Naivasha. “The county government has provided trucks to help families relocate. We have been helping to pay rent for those who lack the finances.”Scientists like Onywere and Muita are hoping for longer-term solutions. “Could we have predicted this so that we could have done better infrastructure in less risk-prone areas?” Onywere said.Muita wants to see a more concerted global effort to combat climate change, as well as local, nature-based solutions centered on Indigenous knowledge, such as “conservation agriculture, where there is very limited disturbance of the land,” to reduce sedimentation of the lakes.But all of this is of little help to Ngome and Wafula, who are still living at the school with their children. As the rest of the world looks forward to the holidays and new year, their future is uncertain. Lake Naivasha’s continuous rise over the past 15 years does not bode well: They have no idea when, or if, their farm will ever be back on dry land.

Disaster after disaster: do we have enough raw materials to ‘build back better’?

Disasters like earthquakes and flood destroy homes and generate vast amounts of waste. Is there a better, greener way to rebuild affected communities?

This Christmas Day marks 21 years since the terrifying Indian Ocean tsunami. As we remember the hundreds of thousands of lives lost in this tragic event, it is also a moment to reflect on what followed. How do communities rebuild after major events such as the tsunami, and other disasters like it? What were the financial and hidden costs of reconstruction? Beyond the immediate human toll, disasters destroy hundreds of thousands of buildings each year. In 2013, Typhoon Haiyan damaged a record 1.2 million structures in Philippines. Last year, earthquakes and cyclones damaged more than half a million buildings worldwide. For communities to rebuild their lives, these structures must be rebuilt. While governments, non-government agencies and individuals struggle to finance post-disaster reconstruction, rebuilding also demands staggering volumes of building materials. In turn, these require vast amounts of natural resource extraction. For instance, an estimated one billion burnt clay bricks were needed to reconstruct the half-million homes destroyed in the Nepal earthquake. This is enough bricks to circle the Earth six times if laid end to end. How can we responsibly source such vast quantities of materials to meet demand? Demand causes problems Sudden spikes in demand have led to severe shortages of common building materials after nearly every major disaster over the past two decades, including the 2015 Nepal earthquake and the 2019 California wildfires. These shortages often trigger price hikes of 30–40%, which delays reconstruction and prolongs the suffering of affected communities. Disasters not only increase demand for building materials but also generate enormous volumes of debris. For example, the 2023 Turkey–Syria earthquake produced more than 100 million cubic meters of debris – 40 times the volume of the Great Pyramid of Giza. Disaster debris can pose serious environmental and health risks, including toxic dust and waterway pollution. But some debris can be safely transformed into useful assets such as recycled building materials. Rubble can be crushed and repurposed as base for low-traffic roads or turned into cement blocks . The consequences of poor post-disaster building materials management have reached alarming global proportions. After the 2004 Indian Ocean Tsunami, for example, the surge in sand demand led to excessive and illegal sand mining in rivers along Sri Lanka’s west coast. This caused irreversible ecological damage to two major watersheds, devastating the livelihoods of thousands of farmers and fisherpeople. Similar impacts from the overextraction of materials such as sand, gravel, clay and timber have been reported following other major disasters, including the 2008 Sichuan earthquake in China and Cyclone Idai in Mozambique in 2019. If left unaddressed, the social, environmental and economic impacts of resource extraction will escalate to catastrophic levels, especially as climate change intensifies disaster frequency. Urgent need for action This crisis has yet to receive adequate international attention. Earlier this year, several global organisations came together to publish a Global Call to Action on sustainable building materials management after disasters. Based on an analysis of 15 major disasters between 2005 and 2020, it identified three key challenges: building material shortages and price escalation, unsustainable extraction and use of building materials, and poor management of disaster debris. Although well-established solutions exist to address these challenges, rebuilding efforts suffer from policy and governance gaps. The Call to Action urges international bodies such as the United Nations Office for Disaster Risk Reduction to take immediate policy and practical action. Building back better and safer After a disaster hits, it leaves an opportunity to build back better. Rebuilding can boost resilience to future hazards, encourage economic development and reduce environmental impact. The United Nations’ framework for disaster management emphasises the importance of rebuilding better and safer rather than simply restoring communities to pre-disaster conditions. Disaster affected communities should be rebuilt with capacity to cope with future external shocks and environmental risks. Lessons can be learned from both negative and positive experiences of past disasters. For example, poor planning of some reconstruction projects after the Indian ocean Tsunami (2004) in Sri Lanka made the communities vulnerable again to coastal hazards within a few years. On the other hand, the community-led reconstruction approach followed after the Bhuj earthquake, India (2001), has resulted in safer and more socio-economically robust settlements, standing the test of 24 years. As an integral part of the “build back better” approach, authorities must include strategies for environmentally and socially responsible management of building materials. These should encourage engineers, architects and project managers to select safe sustainable materials for reconstruction projects. At the national level, regulatory barriers to repurposing disaster debris should be removed, whilst still ensuring safe management of hazardous materials such as asbestos. For example, concrete from fallen buildings was successfully used as road-base and as recycled aggregate for infrastructure projects following the 2004 tsunami in Indonesia and 2011 Tohoku Earthquake in Japan. This critical issue demands urgent public and political attention. Resilient buildings made with safe sustainable material will save lives in future disasters.
