Ocean set ‘alarming’ new temperature record in 2025
- Ocean temperatures set a record high in 2025, according to a new study.
- The authors found that the heat content of the ocean increased by about 23 zettajoules between 2024 and 2025. That’s roughly the equivalent of 210 times humanity’s annual electricity generation.
- The ocean has warmed significantly in recent decades largely because it absorbs roughly 90% of the excess heat trapped in the atmosphere by human-caused greenhouse gases. That makes the ocean a key indicator of global warming.
- Warming ocean temperatures contribute to sea-level rise and to extreme weather events, which were frequent in 2025.

Doug McConnell, interpreter of Northern California, has died, aged 80
- Doug McConnell, who died on January 13, 2026, spent decades using local television to help Northern Californians see their landscapes as shared civic assets rather than scenery, making conservation legible, practical, and personal.
- Best known for Bay Area Backroads and OpenRoad with Doug McConnell, he treated parks, trails, and open space as the result of human choices and public effort, consistently foregrounding the people and institutions that protected them.
- A storyteller shaped by a lifelong love of California’s diversity, he combined curiosity about place with a clear-eyed understanding of governance, showing how history, policy, and persistence shape the land people inherit.
- At a time of mounting environmental strain, McConnell resisted despair by staying close to the work itself, drawing energy from those quietly maintaining and restoring the natural world, and inviting viewers to join them by paying attention.

Study tracks fishing boats to see how heat waves affect fish distribution
- A new study suggests an early way to detect ecological shifts during marine heat waves: Use fishing vessel tracking data.
- The study found that tracking data could provide early detection of extreme northward and inshore shifts in albacore tuna and Pacific bluefin tuna distribution in response to heat waves and showed when such shifts weren’t happening despite high sea surface temperatures.
- The authors position fishers as “apex predators” and build on research that finds that predators are good ecosystem sentinels.

North Atlantic right whale births increase
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Scientists monitoring North Atlantic right whales have recorded an increase in births this winter. Fifteen calves have been identified so far, an encouraging figure for a population that has struggled to sustain itself. There were an estimated 384 […]
Bob Weir, a musician who took the environment seriously
Bob Weir, who died on January 10th, was best known as a founding member of the Grateful Dead. For decades he was also an unusually persistent environmental advocate, one who treated land, forests, and climate not as metaphors but as material systems under pressure. His activism ran alongside his music for most of his adult […]
How are California’s birds faring amid ever more frequent wildfires?
- Long-term research in California shows that many bird populations increase after wildfires and can remain more abundant in burned areas for decades, especially following moderate fires.
- Although some bird species are adapted to fire and benefit from low to moderately severe blazes, megafires in California are becoming more frequent.
- Megafires, scientists say, are unlikely to benefit most bird species and harm those that depend on old-growth forests.
- Wildfire smoke poses a serious threat to birds’ health, with evidence linking heavy exposure to particulate matter in smoke to reduced activity, weight loss and, possibly, increased mortality.

Tatiana Schlossberg, environmental journalist, has died, aged 35
- Tatiana Schlossberg was an environmental journalist who focused on how climate damage accumulates through systems most people rarely see, favoring explanation over exhortation in her reporting and writing.
- Her work, including the book Inconspicuous Consumption, traced the environmental costs embedded in ordinary life, arguing that responsibility is shaped less by individual choices than by infrastructure and incentives.
- In November 2025 she published an essay describing her terminal leukemia, diagnosed shortly after the birth of her second child, writing about illness with the same precision she brought to reporting.
- Her final writing centered on interruption, care, and memory, including the knowledge that her children would grow up with only fragments of her presence.

Andy Mahler, advocate for public forests in America
- Forest conservation in the eastern United States often depended on persistence rather than decisive victories, shaped by slow regulatory processes and fragmented governance that rewarded those willing to keep showing up after attention faded.
- Out of this context grew a form of grassroots activism grounded in local knowledge and personal trust, skeptical of hierarchy and resistant to the idea that extractive outcomes were inevitable or natural.
- Andy Mahler embodied that approach through decades of work protecting public forests, most notably as a central figure in Heartwood, a decentralized network built on sustained relationships rather than efficiency or scale.
- He favored patient, place-based engagement over professionalized advocacy, believing that lasting protection came from continued involvement and shared responsibility rather than fixed outcomes or abstract measures.

In California’s redwoods, scientists rebuild lost ecosystems high up in the canopy
- Roughly 95% of California’s old-growth redwood forests have been logged at least once, leaving mostly young trees and making the overall ecosystem less diverse.
- Fern mats — spongy masses of leather-leaf ferns and decomposed plant matter that build up high in the canopy — are an important part of that system, providing critical habitat for plants and animals in California’s redwood forests.
- Now, a pilot project is trying to restore fern mats to the canopies of particularly robust redwood trees.
- Scientists are finding that manually planting fern mats is also an effective buffer in a warming climate: they mitigate forest temperatures for salmon, birds and a host of other animals.

Kristina Gjerde, defender of the deep ocean, has died
- Much of the global ocean lies beyond national borders, where governance long lagged behind industrial expansion and responsibility thinned with distance from shore.
- Kristina Maria Gjerde helped reframe that problem as one of law and institutions, combining science, legal craft, and persistence to make protection of the high seas politically workable.
- Over two decades, she built and sustained coalitions that turned scattered warnings about deep-sea damage into a binding international framework.
- That effort culminated in the 2023 High Seas Treaty, an agreement whose force lies less in sudden ambition than in the accumulation of careful, patient work.

The year in rainforests 2025: Deforestation fell; the risks did not
- This analysis explores key storylines, examining the political, environmental, and economic dynamics shaping tropical rainforests in 2025, with attention to how policy, markets, and climate stress increasingly interact rather than operate in isolation.
- Across major forest regions, deforestation slowed in some places but degradation, fire, conflict, and legacy damage continued to erode forest health, often in ways that standard metrics fail to capture.
- Global responses remained uneven: conservation finance shifted toward fiscal and market-based tools, climate diplomacy deferred hard decisions, and enforcement outcomes depended heavily on institutional capacity and credibility rather than formal commitments alone.
- Taken together, the year showed that forest outcomes now hinge less on single interventions than on whether governments and institutions can sustain continuity—of funding, governance, science, and oversight—under mounting environmental and political strain.

Tell Hicks, reptile artist
- Tell Hicks helped bring reptiles and amphibians into serious artistic view, treating snakes, lizards, and turtles as subjects worthy of close, unsentimental attention rather than symbols or curiosities. His paintings emphasized accuracy, individuality, and restraint.
- Largely self-taught, he traveled widely and worked directly from field observation, developing meticulous techniques in egg tempera and later fast-drying oils to support highly detailed work, often produced in public settings.
- He became a central figure in herpetological communities in Britain and the United States, helping found the International Herpetological Society, serving as its president, and contributing artwork that circulated through museums, shows, and educational spaces.
- After a life-altering accident left him paralyzed, he adapted his practice and returned to painting, continuing to attend reptile shows and engage with the community that had long formed around his work.

How ‘Adventure Scientists’ provide pioneering data for conservation
Gregg Treinish didn’t start out as an outdoor enthusiast, but found solace and purpose in nature during his youth. After years of enjoying the outdoors, he was left feeling a need to give something back to the world. He found fulfillment by using his passion for outdoor adventures to gather critical data that researchers need […]
Joanna Macy, author and teacher who turned despair into connection and agency
- Joanna Macy — who died on July 19, 2025 at the age of 96 — argued that despair in the face of ecological and nuclear threat was not a weakness but a sign of care, and that refusing to feel it led to paralysis rather than protection. She encouraged people to stay present to what was being lost instead of numbing themselves.
- Drawing on Buddhism, systems theory, and deep ecology, Joanna Macy helped people see themselves not as observers of crisis but as participants within a larger living system. This shift in perspective was central to how she understood responsibility and action.
- Through what became known as the Work That Reconnects, Joanna Macy developed group practices that allowed grief, fear, and anger to be named collectively and transformed into resolve. The emphasis was less on solutions than on restoring a sense of connection and agency.
- As climate change replaced nuclear war as the dominant existential threat, Joanna Macy’s work remained focused on attention rather than reassurance. She insisted that hope was a practice grounded in relationship, not optimism about outcomes.

Century-old corals reveal the Pacific Northwest is acidifying faster than expected
- When compared with historical samples, corals show that the Salish Sea and California Current System are acidifying faster than anticipated because of greenhouse gas emissions. Models indicate that at this rate, carbon dioxide levels in the oceans will continue rising faster than concentrations in the atmosphere.
- Increasingly acidic seas pose growing risks to sensitive marine life, from clams and oysters to any organism with a spine, as well as economically important fisheries and the communities that depend on them.
- British marine ecologist Stephen Widdicombe calls the threat existential. Our continued failure to cut emissions can only lead to “a world where uncontrolled climate change including ocean acidification leaves us with an ocean that is less productive, less diverse and less able to provide humans with the wealth of services that we currently all benefit from,” he said.

Jeff Foott, chronicler of ice, rock, and change, has died, aged 80
- Jeff Foott belonged to a generation of outdoorsmen who moved easily between climbing, science, rescue work, and seasonal labor, guided less by career ambition than by close attention to the natural world. His ethic was shaped early, long before environmental concern became institutionalized.
- Trained as a marine biologist, he turned to photography and film as a way to show how wildlife lived and what was at risk, producing more than 40 films and widely published images for outlets such as National Geographic, the BBC, and PBS.
- His visual work favored clarity and restraint over spectacle, whether documenting sea otters, alpine ice, or red rock landscapes increasingly altered by a warming climate. He remained attentive to environmental change without turning his work into overt argument.
- In his own words, what mattered to him was not climbing but whether people would know that some tried to act on concern for climate, democracy, and the things held in common. He let photographs carry the burden of persuasion.

Statewide survey aims to put California’s fungi on the conservation map
- A state-funded survey has sampled and collected fungi species from across California, identifying hundreds of new-to-science species.
- It’s part of a statewide effort to protect biodiversity, which has yielded thousands of specimens and is the first of its kind in North America.
- Fungi are often neglected compared to the attention given to plants and animals, yet they play an important role in maintaining ecological health by supporting plant growth and storing carbon.
- Understanding fungi’s role in nature has implications for conservation and for forest restoration as wildfires grow larger and more frequent. Other researchers in California are working on putting fungi to use cleaning up polluted areas.

Zombie urchins & the Blob: California sea otters face new threats & ecosystem shifts
- Southern sea otters living along California’s coast are struggling in warmer seas, with new threats and changing food sources. They, like the other two sea otter subspecies, are classified as endangered.
- Human disturbance, especially in Monterey Bay, is limiting the otters’ ability to forage, impacting mother and pup survival. Meanwhile, sharks are expanding their range as waters warm, with increasing attacks on otters.
- Following a mass die-off of the purple sea urchin’s predators — sunflower and ochre sea stars — the urchins decimated kelp forests, which are important sea otter habitat. Mussels then proliferated, replacing urchins in the otter’s diet, and invasive green crabs are now also on the menu.
- Otter numbers seem to be dropping, but a definitive census has not been conducted since 2019. A new population estimate based on data and statistical modeling is due to be released soon.

‘Neither appropriate nor fair’: Ecuador ordered to pay oil giant Chevron $220m
Indigenous and rural communities in Ecuador’s Amazon have condemned an international arbitration ruling that ordered Ecuador to pay more than $220 million to U.S. oil giant Chevron. The sum is to compensate the company for alleged denial of justice in a trial that found Chevron, operating through its predecessor Texaco, guilty of widespread environmental damage […]
Earth’s freshwater fish face harsh new climate challenges, researchers warn
- Climate change is rapidly altering freshwater ecosystems — raising temperatures, altering flood pulses and oxygen levels — and driving complex, region-specific changes in how fish grow, migrate and survive.
- Long-term U.S. data show sharp declines in cold-water fish as streams and lakes warm, while warm-water species gain only slightly. Some cold-adapted species are now disappearing as deep waters cease being a cold refuge.
- From Africa to the Arctic, impacts are emerging, including stronger lake stratification, declining fisheries and rivers turning orange as thawing permafrost releases toxic metals. Declining freshwater fisheries increasingly put food security at risk, especially affecting diets and health in traditional and Indigenous communities.
- Scientists say management and conservation techniques rooted in past conditions no longer work. New approaches must anticipate shifting baselines as climate change rapidly accelerates.

Choosing coexistence over conflict: How some California ranchers are adapting to wolves
- California’s expanding gray wolf numbers — a conservation success for an endangered species — have worried ranchers in recent years as wolf-related livestock kills mount.
- Some ranchers are adapting to the changing landscape, using short-term nonlethal deterrents, some of which are funded by a state compensation program.
- A few ranchers are exploring long-term approaches, such as changing their ranching practices and training their cattle to keep them safe from wolves.
- While change is hard, ranchers acknowledge that learning to live with the new predator is the only way forward, and it pays to find ways to do so.

Chris Grinter has spent much of his life surrounded by insects
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Chris Grinter has spent much of his life surrounded by insects — though not in the way most people imagine. As senior collection manager of entomology at the California Academy of Sciences, he oversees one of the world’s […]
Deep-sea mining interests raise alarms among Mariana Trench communities
- On Nov. 12, the Bureau of Ocean Energy Management (BOEM) issued a request for information (RFI), indicating its interest in “leasing” marine minerals located on the CNMI’s outer continental shelf, a process that would allow commercial mining to proceed on the seabed of the Commonwealth of the Northern Mariana Islands (CNMI).
- Critics say BOEM’s handling of the RFI was rushed and opaque, noting that the agency failed to consult the CNMI and Guam governments or communities before opening a brief 30-day window for public comment.
- Critics also warn that deep-sea mining could irreversibly harm the marine environment and undermine the region’s deep cultural ties to the ocean, while amounting to another form of U.S. colonial exploitation in the Pacific.

Boom in burning waste for fuel could put human health and environment at risk
- Refuse-derived fuel (RDF) — conglomerated waste often composed of up to 50% plastic — is being burned globally in waste-to-energy incinerators, cement kilns, paper mills, and by other industries.
- Proponents say RDF reduces fossil fuel use and produces cleaner energy, while diverting waste from landfills.
- Critics say a lack of monitoring often hides RDF’s true environmental and human health footprint, and that when burned alongside fossil fuels, the technology can significantly worsen pollution. Health issues potentially connected to RDF contaminants range from cancer to hormone disruption.
- That’s a major concern as RDF ramps up, with countries in the Global South especially starting to use and dispose of waste in this way. Burning RDF and the incineration of plastic waste has been linked to greenhouse gas emissions and also extremely toxic pollutants such as dioxins.

With a target on their bellies, can California’s sturgeon survive?
- California’s green sturgeon and white sturgeon face numerous threats from dams, harmful algal blooms and overfishing.
- White sturgeon are highly prized for their eggs, which are made into caviar.
- Their numbers have dropped so precipitously that they’re now being considered for protection under the California Endangered Species Act.
- The state banned commercial sturgeon fishing in 1954, but the amount of poaching and caviar trafficking is unknown, and there have been cases linked to criminal networks involved in other illegal activities.

Another threat to reefs: Microplastic chemicals may harm coral reproduction
- Plastic pollution is a growing problem in many reef ecosystems, and its effects are not well understood.
- Most previous research has focused exclusively on adult corals and their interactions with plastic particles, rather than larval stages of coral or the chemicals from plastic that leach into water.
- In a new study, researchers exposed coral larvae from two different species to four different plastic chemicals and found that they negatively impacted coral larvae settlement.

Wildfire burns climate-vulnerable Joshua trees in US national park
A wildfire in California’s Joshua Tree National Park burned through some 29 hectares (72 acres) of land during the recent federal government shutdown in October and November. That’s a small fire by California standards, but firefighters estimate it scorched roughly 1,000 of the park’s iconic Joshua trees, according to The Los Angeles Times. The burned […]
Turning adventure into data
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Gregg Treinish’s turning point came somewhere between mountain ranges and moral unease. Years of wandering through wilderness had left him restless. “I was spending years in the wilderness, doing long expeditions, and I began to feel selfish for […]
‘Silent epidemic of chemical pollution’ demands radical regulatory redo, say scientists
- An international team of 43 scientists has called for a “paradigm shift” in toxicology and chemical regulation globally after having found severe lapses in current regulatory systems for evaluating the safety of pesticides and plastics derived from petrochemical byproducts.
- The researchers note that the full commercial formulations of common petrochemical-based pesticides and plasticizers have never been subjected to long-term tests on mammals. Only the active ingredients declared by chemical companies have been assessed for human health risks, while other ingredients have not.
- The scientists found that synthesized pesticides and plasticizers contain petroleum-based waste and heavy metals such as arsenic that can make them “at least 1,000 times more toxic” than the active ingredients alone, posing chronic disease and health threats, especially to children — claims that the chemical industry denies.
- Researchers urge lowering the admissible daily intake, or toxicity threshold, for already approved chemical compounds; long-term testing on the full formulations of new pesticides and new plasticizers; and requiring all toxicological data and experimental protocols for approved commercial compounds be made public.

Jean Beasley, who turned her young daughter’s dying wish into a mission to save sea turtles, has died
- After the death of her daughter Karen in 1991 and her dying wish to “do something good for sea turtles,” Jean Beasley committed herself to sea turtle conservation on Topsail Island, North Carolina.
- She founded the state’s first sea turtle rehabilitation center, beginning in a cramped 900-square-foot space and growing it into a respected 13,000-square-foot hospital and public education facility in Surf City.
- Beasley valued both direct action and education, believing that saving one turtle mattered but inspiring others—especially children—to care about the ocean could save many more.
- Her decades of work helped protect more than 3,000 nests and rehabilitate at least 1,600 turtles, while also motivating future conservationists and proving that a daughter’s dying wish could become a movement of hope.

First state-authorized killings mark escalation in California’s management of wolves
- California’s wildlife department killed four gray wolves in the Sierra Valley in late October, in a dramatic escalation of tactics to address growing predation of cattle by the canids and despite protection under state and federal endangered species laws.
- The department says the wolves killed at least 88 cattle in Sierra and Plumas counties and continued to target livestock despite months of nonlethal deterrents deployed to drive them away.
- The state employed lethal action despite its compensation program, which pays ranchers for cattle killed by wolves, and additional federal subsidies paid to the livestock industry at large.
- The state wildlife agency confirmed a new pack –– the Grizzly pack–– earlier this week with two adults and a pup. Though the state’s wolf population remains small and vulnerable, ranchers are increasingly concerned about livestock deaths.

It’s ‘whack-a-mole’: Alarming rise in pet trade fuels wildlife trafficking into California
- California has become a wildlife trafficking hotspot in the U.S., with a notable spike in live animals smuggled across the southern border to be sold as pets, from monkeys and exotic birds to venomous snakes.
- The state has three high-traffic border crossings with Mexico and millions of tons of cargo shipped through some of the nation’s busiest airports and seaports. With limited staff, resource-strapped agencies face serious challenges in policing the illegal import of protected plants and animals into California.
- Poachers also target California’s native plants and reptiles, threatening local species. Meanwhile, some imported animals get loose and become invasive species that destroy ecosystems or may carry diseases, creating public health risks.
- As traffickers exploit new technologies and follow market demand for different animals, enforcement officials struggle to control the influx of illegally traded species.

Inside California’s race to document its insects: A conversation with Chris Grinter
- Christopher C. Grinter, Senior Collection Manager of Entomology at the California Academy of Sciences, discussed his work documenting California’s insect diversity through the California All-Taxa Biodiversity Inventory (CalATBI).
- He described how DNA barcoding and voucher specimens together form a lasting record of life, helping scientists track species and environmental change across the state.
- Grinter reflected on both the urgency of discovery amid biodiversity loss and the promise of new technologies and collaborations that make large-scale insect research possible.
- He spoke with Mongabay founder and CEO Rhett Ayers Butler in October 2025.

Scientists slam Canada-US proposal to lower trade protections for peregrine falcons
- Peregrine falcons, the world’s fastest and most widespread raptors, recovered spectacularly after pesticides that nearly drove them to extinction were banned and captive-bred birds were rewilded, making the effort a remarkable conservation success story.
- Although the species is no longer endangered, international commercial trade in this bird, coveted by falconers, is banned for wild-caught specimens and highly regulated for captive-bred ones. Canada and the U.S. propose loosening those restrictions, a proposal that will be voted on at the upcoming meeting of CITES, the global wildlife trade treaty.
- Some raptor scientists have concerns. The Canada-U.S. downlisting proposal includes population estimates of just a few subspecies; many others are understudied. Some populations have declined in recent years and illegal trade continues.
- Until there are safeguards against unsustainable trade and accurate assessments for all subspecies, conservationists say lowering protections could undo the efforts that have brought this bird back from the brink.

Trade in marine fish for aquariums includes threatened species, lacks oversight: Study
- A new study of major U.S.-based online retailers of marine fish bound for aquariums found that nearly 90% of traded species are sourced exclusively from the wild, including a number of threatened species, and that the trade is poorly tracked.
- The study raises concerns about the ecological impact of the trade on marine ecosystems, including around coral reefs, in countries such as Indonesia and the Philippines, where the fish are caught.
- Experts called for more work to develop sustainable fisheries and aquaculture in coastal communities in the Global South, and for building consumer awareness and establishing eco-certification schemes.

From waffle gardens to terraces, Indigenous groups revive farming heritage in America’s deserts
- Native American farmers in the southwestern United States have long deployed weather-adaptive techniques to grow crops such as corn and beans in high-desert environments only occasionally visited by rain.
- In recent years, a variety of tribal groups have arisen to train the next generation of Native American farmers as a means of promoting cultural identity and improving self-sufficiency, health and well-being while using farming strategies that have worked for centuries on arid lands.
- The techniques range from hillside terracing and “waffle” gardening, to water conservation and leveraging microclimates on a piece of land.
- During Native American Heritage Month in November, Mongabay spoke with the leaders of these groups about their traditional farming techniques and how they can be replicated in increasingly dry regions around the world.

At her memorial, a call to carry Jane Goodall’s hope forward
- Jane Goodall’s memorial at Washington National Cathedral brought together scientists, diplomats, activists, and children for a service rooted in gratitude rather than grief, reflecting a life that reshaped how the world understands the natural world.
- Speakers described her quiet authority and her belief that conservation depended on relationships, resilience, and collective purpose, with Anna Rathman urging the audience to continue the work Jane had begun.
- Francis Collins and Leonardo DiCaprio offered personal reflections on her blend of scientific rigor, moral clarity, humor, and hope, recalling how she moved through the world with curiosity and purpose, insisting that every individual could make a meaningful difference.
- Her grandson Merlin van Lawick spoke of the wonder she carried through her life and promised to continue her mission, underscoring a service that closed not with finality but with an invitation to carry her light forward and to show, through action, that hope endures.

What Central Park’s Squirrel Census says about conservation tech: Interview with Okala’s Robin Whytock
- At the end of New York Climate Week this year, ecologist Robin Whytock spent a few hours in Central Park counting squirrels.
- His mission was to prove how scalable tech solutions could help make biodiversity monitoring easier and more efficient.
- Whytock, who runs AI-powered nature monitoring platform Okala, said that while data-gathering tools have become easily accessible, analyzing massive amounts of biodiversity data still remains a challenge.

Turning outdoor exploration into environmental discovery: Gregg Treinish and the rise of Adventure Scientists
- Gregg Treinish, founder of Adventure Scientists, has built a global network of trained volunteers who collect high-quality environmental data for researchers, agencies, and conservationists. His organization bridges the worlds of outdoor adventure and scientific rigor.
- From microplastics and illegal timber to biodiversity mapping, Adventure Scientists’ projects have filled crucial data gaps and influenced policy, research, and corporate practices around the world.
- In California, Treinish’s team is partnering with the California All-Taxa Biodiversity Inventory (CalATBI) to help catalog the state’s immense diversity through thousands of insect and soil eDNA samples collected by volunteers.
- Treinish spoke with Mongabay founder and CEO Rhett Ayers Butler in October 2025 about scaling trust-based citizen science, the value of human observation in nature, and why adventure remains a powerful gateway to environmental action.

Night dives reveal hidden alliances between young fish and larval anemones
- A new study, drawing on nighttime underwater photography, documented previously unknown “symbiotic associations” between juvenile fish and larval anemones, with some fish staying close to the anemones, and others carrying them around.
- The study suggests the fish may gain protection from predators by associating with the toxic anemones, while the anemones could benefit from being transported by the fish to new parts of the ocean.
- An outside expert also proposed that anemones might receive additional benefits, such as nutrients from the fish’s excretions or from food scraps left behind.
- All of the experts emphasized that more research is needed to fully understand the dynamics of these relationships.

California’s grand insect census
- Austin Baker and his team at the Natural History Museum of Los Angeles County are leading an ambitious effort to DNA-barcode every insect species in California as part of the statewide CalATBI initiative to “discover it all, protect it forever.”
- The project combines traditional specimen collection with modern genetic sequencing to build a comprehensive biodiversity library, revealing surprising hotspots of insect life—from foggy coasts to the species-rich Mojave Desert.
- By creating a genetic baseline of California’s insect diversity, the team hopes to track future ecological change, inform conservation priorities, and preserve the record of countless species that might otherwise vanish unnoticed.
- Baker was interviewed by Mongabay’s Rhett Ayers Butler in October 2025.

Drax pellet mill wins appeal to raise pollution limits in small Mississippi town
- Industrial forest biomass wood pellet mills now dot rural areas around the globe, with plants concentrated in the U.S. Southeast, and other major facilities found in Canada, the EU, Russia, Vietnam, Indonesia and elsewhere. The EU, Japan and South Korea burn most of the wood pellets currently being produced.
- Pellet mills have increasingly come under fire from rural communities who accuse large-scale manufacturers like the U.K.’s Drax and Enviva in the U.S. of air pollution, dust and noise violations, which harm residents’ health and quality of life. A 2023 study found that pellet mills in the U.S. Southeast release 55 hazardous pollutants.
- In a rare victory last April, the town of Gloster, Mississippi, won a major pollution permitting battle against Drax’s Amite BioEnergy pellet mill — one of the largest in the world. But at an October appeal meeting, the Mississippi Department of Environment Quality reversed itself, giving Drax permission to pollute more today than previously.
- The Drax plant has been fined more than $2.75 million since 2016 for exceeding toxic emissions limits. Drax says it has invested millions in pollution mitigation technology to prevent future pollution. A law firm representing Gloster citizens is filing a federal lawsuit alleging Drax has been violating the Clean Air Act since opening the Gloster plant in 2015.

Radar study shows when offshore turbines pose greatest risks to migrating birds
- A new study looks at bird migration patterns over open ocean in an attempt to assess how much risk offshore wind turbines and other marine infrastructure might pose to them.
- The authors used radar data from U.S. coastal weather stations to find that hundreds of millions of birds migrate over tight windows of time in the spring and fall while flying at slightly lower elevations on average than over land.
- This puts a proportion of them at risk of being killed by wind turbines, but that risk could be mitigated with dynamic management that accounts for their patterns, according to the study.
- The Trump administration, in office since January, says it doesn’t support offshore wind development, but the research has long-term implications and could be used more immediately for mitigating the impact of offshore oil and gas projects.

Booming sea otters and fading shellfish spark values clash in Alaska
- In Alaska, a state brimming with iconic wildlife — from grizzly bears to king salmon, humpback whales to harbor seals — the charismatic, densely coated sea otter stands out as perhaps the state’s most hotly debated, controversial species.
- Sea otters were nearly hunted into extinction a century ago for their luxurious pelts. But they have been surging in population in the Gulf of Alaska, bringing both benefits to nearshore ecosystems and drawbacks to the shellfish economy (due to the otters’ voracious caloric needs).
- Described by commercial shellfish harvesters and Native Alaskans as pillagers of clams and crabs, sea otters are seen by many marine biologists as having positive impacts on kelp forests — important for biodiversity and carbon storage. Scientists stress that shellfish declines are complex, with sea otters being just one among multiple causes.
- Native Alaskans are the only people given free rein to hunt sea otters. But long-standing federal regulations stipulating who qualifies as Native Alaskan make it illegal for most to manage their own waters. Tribes are fighting for regulatory changes that would enable them to hunt and help balance booming sea otter populations.

As wolves roam California, livestock losses remain low, yet ranchers’ fears grow
- In California, as wolf numbers grow — a remarkable return after a century — livestock producers are increasingly worried as these predators occasionally take down cattle.
- Gray wolves are an endangered species, protected under both federal and state laws, complicating the balance between conservation and economic losses, though livestock kills remain low.
- California introduced a compensation program that pays ranchers for direct and indirect losses from wolves as a way to mitigate conflicts, but ranchers say this program isn’t scalable with expanding wolf numbers. The livestock industry also receives substantial taxpayer-funded subsidies.
- Wolves were extirpated from California a century ago, so ranchers haven’t lived alongside them for generations and are pushing to remove all protections for the species. Conservationists argue coexistence is the only way forward.

Drone surveys offer early warnings on whale health and survival
- Scientists have deployed drones and are using photogrammetry to determine how climate change is impacting the health of whale populations.
- By collecting the measurements of whales, scientists are able to track how environmental factors impact the growth and reproduction of right whales off the coast of New England and orcas in Alaska.
- Using the data, they found that a marine heat wave in 2013 reversed the revival of the population in Alaska that had plummeted after the Exxon Valdez oil spill in 1989; they also noticed that the whales didn’t grow as much as they should have.
- The method also enabled scientists to detect pregnant whales well in advance, allowing them to monitor if the pregnancy was successful or not.

Warmer climate could slash threatened whitebark pine territory within decades: Study
- A study published Sept. 2 in the journal Environmental Research Letters forecasts an 80% reduction in the area with suitable climates for whitebark pine by the mid-21st century.
- This long-lived, high-elevation tree plays a critical role in mountain ecosystems in western North America, providing food for wildlife and regulating water supplies.
- But a disease-causing fungus has ravaged whitebark and other pine species, compounded by other threats, such as wildfire, mountain pine beetles and climate change.
- The research, which identifies areas that will likely be climatically suitable for whitebark pine in the future, could help guide restoration efforts to save the species.

Scientists hope underwater fiber-optic cables can help save endangered orcas
SAN JUAN ISLAND, Wash. (AP) — Scientists from the University of Washington recently deployed a little over 1 mile of fiber-optic cable in the Salish Sea to test whether internet cables can monitor endangered orcas. The technology is called Distributed Acoustic Sensing. It transforms cables into continuous underwater microphones that can pinpoint whale locations and […]
Diane Keaton, actress and animal advocate, has died, aged 79
Fame, for Diane Keaton, was never an excuse to look away. In a profession built on performance, she turned her gaze outward—to the voiceless and the overlooked. While audiences remember her for Annie Hall’s nervous charm and The Godfather’s quiet strength, animal advocates will remember her for something else: an unflinching compassion that extended well […]
Uphill battle to save California’s endangered mountain yellow-legged frog
- Conservation organizations released 350 mountain yellow-legged frogs earlier this year, marking another step in an intensive, long-running reintroduction project for this highly endangered species in Southern California.
- Once abundant across its range, populations have declined drastically because of invasive fish species, climate change impacts, and the deadly chytrid fungus that is wiping out amphibians worldwide.
- Conservationists are testing out new ways to boost survival rates of released frogs. Though it’s hoped the species may one day recover, today they are locked in a fight against extinction.

Canada’s prime minister discussed reviving contentious Keystone XL pipeline with Trump
TORONTO (AP) — A Canadian government official familiar with the matter says Prime Minister Mark Carney raised the prospect of reviving the contentious Keystone XL pipeline project during his White House meeting with U.S. President Donald Trump this week. A Canadian company pulled the plug on it four years ago after the Canadian government failed […]
Will California’s marine mammal conservation success come undone?
- With protection, many of California’s marine mammals — including whales, sea lions and seals — have made remarkable recoveries over the last half-century since bipartisan passage of the U.S. Marine Mammal Protection Act.
- However, climate-linked changes have now pushed the gray whale population into a state of collapse.
- Despite comebacks, marine mammals face a plethora of threats from pathogens, pollutants — including oil and plastic — disappearing food and more.
- In California, people and institutions are fighting for marine mammals and ocean biodiversity, but federal protections could be substantially weakened if proposed amendments to the Act move ahead.

Wildfire smoke could kill 71,000 people per year in the US by 2050, study warns
- A new Nature study projects wildfire smoke will cause 71,000 excess deaths annually in the U.S. by 2050, representing $608 billion in damages that exceed all other estimated climate costs combined.
- Researchers linked climate conditions to fire emissions, smoke concentrations and mortality using historical death records and satellite data, finding that approximately 41,000 annual deaths already occur from wildfire smoke.
- More than half of projected deaths occur in Eastern U.S. states due to population density and long-range smoke transport, with health impacts lasting up to three years after exposure.
- Even if nations dramatically cut emissions, more than 60,000 Americans will still likely die annually from wildfire smoke by 2050 because Earth’s climate system takes decades to respond to changes, making adaptation strategies like air filters and forest management critical despite their limitations.

Tony Pritzker’s patient strategy for the planet
- Tony Pritzker, an engineer by training and philanthropist by practice, frames his environmental giving around patience, pragmatism, and clearly defined goals, from cleaning up Santa Monica Bay to fostering early-career innovators.
- He emphasizes local action as the foundation of global change, citing successes such as stormwater treatment infrastructure in Los Angeles and the educational initiatives of Heal the Bay.
- Pritzker blends optimism with realism, believing that consumer demand, science, and efficiency can align business, policy, and philanthropy to address environmental challenges without partisanship.

Impacts of US government shutdown on the EPA
WASHINGTON (AP) — The Environmental Protection Agency faces challenges during a government shutdown. The agency’s mission to protect health and the environment is at risk without a federal budget. Former EPA officials express concerns that polluters may exploit the situation with an agency that has already seen massive staff cuts and dramatic shifts in policy. […]
Jane Goodall (1934–2025): primatologist, conservationist, and messenger of hope
- Jane Goodall, who began her career in 1960 with little formal training, transformed science’s understanding of chimpanzees and in the process reshaped the boundary between humans and animals. Her discoveries at Gombe forced the recognition of animal minds, emotions, and cultures once thought unique to humanity.
- She built on that science with activism: founding the Jane Goodall Institute in 1977, launching community-centered conservation programs across Africa, and creating sanctuaries for orphaned chimps. In 1991 she established Roots & Shoots, which grew into a vast youth movement spanning more than 100 countries.
- Beyond research and institutions, she became a global messenger, traveling up to 300 days a year to speak with audiences ranging from heads of state to schoolchildren planting trees. She insisted that empathy and objectivity could coexist and called on each person to remember that “every day you live, you make some kind of impact.”
- She described humanity as standing at the mouth of a dark tunnel with a star shining at the end—hope. To reach it, she said, required collective effort. That conviction defined her legacy: a life that reminded the world that hope is not wishful thinking but a discipline, and that every individual makes a difference.

Northeast Pacific endures fourth-largest marine heat wave on record
The Northeast Pacific ocean, off the U.S. West Coast, is experiencing its fourth-largest marine heat wave since record-keeping began in 1982. “The extent of the current Pacific marine heatwave should be surprising … but unfortunately, record breaking heat is our new norm,” Chris Free, a marine scientist at the University of California, Santa Barbara, told […]
California’s kelp forests struggle to recover a decade after collapse
More than 10 years after unusually high water temperatures in the Pacific Ocean killed off Northern California’s aquatic kelp forests, the region has still not recovered, reports David Helvarg, executive director of ocean conservation group Blue Frontier, for Mongabay. From 2013 to 2017, a mass of unusually warm water nicknamed “the Blob” hugged California’s coast, […]
