In Brazil’s general election on Oct. 4, incumbent leftist President Luiz Inácio Lula da Silva finished second to far-right Flávio Bolsonaro, a senator and son of former President Jair Bolsonaro, who was barred from public office after being convicted of planning a coup d’état. The two candidates will face each other in a second-round vote on Oct. 25 as neither candidate won more than 50% of the vote needed for a first-round victory. Flávio Bolsonaro won the majority of votes in eight of the 10 Amazon municipalities that cleared the most rainforest over the last decade, according to an analysis by Sumaúma, an Amazon-based publication. Sumaúma compared official results from the first-round votes with satellite deforestation data from Brazil’s National Institute for Space Research. Jair Bolsonaro’s presidency coincided with a historic spike in deforestation. Lula took office in 2023. Starting in August 2025, Amazon deforestation fell to the lowest level in more than a decade. Novo Progresso in Pará state was the site of the 2019 “Day of Fire” when local residents, many Jair Bolsonaro supporters, purposely set hundreds of forest fires. Flávio Bolsonaro won 84% of the vote in Novo Progresso. In the municipality of Altamira, where the Lula administration blacklisted more than 500 farms for illegal deforestation last year, Flávio Bolsonaro won 63% of the vote. Nestled between Altamira and Novo Progresso is the site of the largest land grab in Brazilian Amazon history. Lula won the vote in two of the 10 most deforested municipalities. He won…This article was originally published on Mongabay

Oil slicks from ships and offshore oil platforms cover nearly 1.6 million square kilometers (618,000 square miles) of the ocean surface each year, an area slightly larger than the nation of Mongolia. The estimate comes from a recent report by Skytruth, a U.S.-based nonprofit that used satellite imagery, machine learning and vessel tracking data to trace global oil pollution in the oceans between 2023 and 2025. According to John Amos, CEO of Skytruth, this kind of pollution was largely invisible before satellite imagery made it possible to track. “Any vessel operator could be pretty confident that nobody was going to notice what they were doing out in the middle of the ocean,” Amos told Mongabay by phone. “So that’s changed. We can see it now.” Map courtesy of SkyTruth. Much of the vessel oil slicks come from bilge waste, a mix of oil and water that collects in the bottom of a ship’s hull during operation. Tankers sometimes also wash out their cargo holds and flush crude oil residue into the sea. “It’s nasty oily dirty gunk that you just want to get rid of,” Amos said. “And the easiest thing to do with it is just pump it out into the ocean while you’re at sea.” According to the report, most of these discharges are illegal under MARPOL, the international treaty on pollution from ships. A MARPOL treaty adopted in 1973 allows vessels to discharge bilge water containing no more than 15 parts of oil per million parts of…This article was originally published on Mongabay

Rising sea levels due to climate change could damage hundreds of thousands of properties and millions of hectares of land along Australia’s coastline by 2100, according to a recent study. This could cost the country an economic loss of $855 billion, researchers estimate. To calculate the costs, researchers in Australia used existing projections of sea level rise and storm surges to map out the areas that could suffer flooding by 2100. Then they identified all the houses, properties, agricultural land, and other land and infrastructure in the vulnerable areas and used real estate sources to estimate their values and arrive at what their damage could cost. The analysis showed that by 2100, under a scenario where greenhouse gas emissions remain moderate, sea level rise and storm surges could damage roughly 268,000 properties and 2 million hectares (4.9 million acres) of land in Australia. That’s a present-value economic loss of $855.1 billion. Under a high-emissions scenario, nearly 720,000 properties and 3.7 million hectares (9.1 million acres) of Australian coastal properties could suffer damage, amounting to present-value losses of up to $1.91 trillion. “Sea level rise may physically affect a large number of Australians who live near the coast, as the majority of Australians live within 50 kilometres [31 miles] of the coastline,” Tom Kompas, study lead author and a professor of environmental economics and biosecurity at the University of Melbourne, said in a statement. Australia’s coastline is massive, extending roughly 34,000 kilometers (21,000 miles). The analysis found that every region of…This article was originally published on Mongabay

A case has been brought to the East African Court of Justice (EACJ) over the Kenyan government’s plan to build a 2,000-5,000-megawatt nuclear power plant in Bondo, near the eastern shore of Victoria Lake, Africa’s largest freshwater lake. The project has been the source of numerous protests from residents since it was announced. A Strategic Environmental Assessment (SEA) report produced in 2023 by Kenya’s nuclear power program noted that nuclear power should be avoided in the Victoria Lake region, citing volcanic hazards that could impair nuclear safety. However, the nuclear plant project is proceeding, despite the SEA finding. “I filed a reference at the East African Court of Justice on two grounds,” Dickens Ochieng, told Mongabay in a phone call. Ochieng is a resident of Siaya County, where the facility is located, and a human rights lawyer with J. Henry and Company Advocates, the law firm that filed the case on Sept. 23. “First, I want the court to determine if we should even have that nuclear power plant in Victoria Lake given the ecological and environmental risk that may be associated with it,” Ochieng said. “Then, I am asking for the project to have a transboundary environmental impact assessment, as Victoria Lake is not only a Kenyan matter.” Victoria Lake is shared by Kenya, Uganda and Tanzania. Roughly 40 million people across the three countries depend on the lake for their livelihoods, food security and drinking water. Millions more depend on the river that drains from Lake Victoria and…This article was originally published on Mongabay

Plastic pollution could disrupt the bioluminescent light produced by deep-sea organisms, researchers warn in a letter in the journal Cambridge Prisms: Plastics. When deep-sea organisms ingest plastics, it could disrupt the chemical pathways that create bioluminescence and damage the tissues in their bodies, impairing their ability to find food and a mate, the authors said. In the deep sea, up to 80% of organisms with complex cells are believed to be bioluminescent, the only source of light in the darkest parts of the ocean. The light these organisms create is essential for their survival and reproduction, the letter notes. Disruption of their bioluminescence could negatively impact food webs and ecosystem functions in the deep sea, the largest and least-explored biome on Earth, the letter says. In an email to Mongabay, co-author Renjith VishnuRadhan of Amity University in India offered the example of an anglerfish. “It is widely recognizable from documentaries and films such as Finding Nemo,” he said. “Female deep-sea anglerfish have a modified dorsal spine ending in a luminous lure called the esca. Light produced by symbiotic bacteria helps attract prey and may also assist with recognition or communication in darkness.” It’s well-established that bacterial bioluminescence can be affected by pollutants, VishnuRadhan said, and ingestion of toxic plastic additives by anglerfish could disrupt the bacterial symbiosis in the lure, theoretically affecting its luminous signaling. The authors note there’s some evidence of plastic pollution impacts on deep-sea ecosystems, but scientists lack the high-quality data and observations needed to understand the…This article was originally published on Mongabay

Lulingu, a Grauer’s gorilla (Gorilla beringei graueri), was reintroduced to Virunga National Park, in eastern Democratic Republic of Congo in 2024. In May 2026, Lulingu gave birth to a new baby, bringing hope for the species and excitement for the conservationists working there. “The baby and the mother are doing perfectly well. It really makes us happy. We are proud of her, it is also a bit of our success. Imagine, we knew her as a baby, we watched her grow, be rehabilitated and now she is a mother,” Jackson Kabuyaya Mbeke, country director of the DRC Gorilla Rehabilitation and Conservation Education Center (GRACE), told Mongabay by phone. Lulingu arrived at GRACE, a 16-hectare (40-acre) wildlife sanctuary, in 2016 when she was 18 months old. She was rescued from an illegal wildlife trafficking network by the Congolese Wildlife Authority (ICCN) and the NGO Gorilla Doctors. The sanctuary gave her space to socialize and play in a setting close to her natural habitat, under the watchful eyes of adoptive gorilla mothers. Lulingu was later reintroduced into the wild near Mount Tshiaberimu, a remote part of Virunga National Park. “The purpose of our sanctuary is to take in rescued gorillas, but also to care for them until they can be released into the wild. The fact that Lulingu has had a baby is a sign that she has adapted well to life in the wild,” Kabuyaya Mbeke explained. “By reintroducing them into the wild, we also hope to repopulate forests that have been…This article was originally published on Mongabay

Scientists have described a species of tiger cat that was previously unknown to science. From Bolivia’s Yungas cloud forests, it is the first discovery of a living novel cat species in more than 100 years. The tilcayo (Leopardus tilcayo) takes its species name from the name locals already had for it. Paola Nogales-Ascarrunz, a National Geographic explorer who discovered the species and co-author of the Current Biology paper that describes it, said the name honors traditional knowledge in the region. The tilcayo is smaller than a domestic cat at 1.4 kilograms (3 pounds). It has rounded ears, a slender body and a coat with large spots. “I have the honor of naming a cat, and that’s a really big thing,” Nogales-Ascarrunz, who is also a researcher at the Universidad Mayor de San Andrés in La Paz, Bolivia, told Mongabay by phone. Photo © Fernando Faciole/National Geographic. For decades, researchers lumped small spotted cats across South America under a single species name: Leopardus tigrinus or tiger cat. However, evidence had been mounting for years that the group might contain several species. In the article published on Sept. 17, researchers unwound the species’ genetic web and confirmed at least four distinct species. Many newly recognized small cat species result from this kind of taxonomic reshuffling:  Researchers find a subspecies is actually a distinct species; or two different species that had been lumped together are separated. But the tilcayo was different. Researchers knew a cat occurred in the Yungas cloud forests, but it…This article was originally published on Mongabay
