How did we identify fossil fuels to be remains of fossils, particularly those of dinosaurs?

The article explains the scientific methods used to identify fossil fuels as the remains of ancient life, debunking the common misconception that they primarily originate from dinosaurs. It details how physical evidence (plant imprints in coal), chemical markers (hopanoids, steranes in crude oil), and isotopic analysis (carbon-12 enrichment due to photosynthesis) confirm their organic origin. The article clarifies that oil and natural gas are mainly derived from ancient plankton and algae, while coal comes from ancient forests and swamps. The association of dinosaurs with fossil fuels is attributed to a 1930s marketing campaign by Sinclair Oil Corporation.

Understanding the disappearance of Egyptian Vulture in Tamil Nadu

The Egyptian Vulture (Neophron percnopterus), once common across Southern India, has become locally extinct in The Nilgiris and no longer breeds in Tamil Nadu, with fewer than 150 resident individuals estimated across Karnataka and Tamil Nadu. Globally listed as Endangered by IUCN, its decline is attributed to veterinary NSAIDs like diclofenac, electrocution, poisoning, habitat disturbance, and changes in traditional livestock rearing. While Karnataka holds the most significant remaining breeding populations, Tamil Nadu serves as a wintering habitat for migratory birds. Conservationists are urging for coordinated efforts, including the establishment of an Egyptian Vulture Conservation Breeding Programme in Tamil Nadu, building on successful models by the Bombay Natural History Society (BNHS) for other vulture species.

It’s time for Tamil Nadu to segregate solid waste at source

The article discusses the challenges and implementation of the Solid Waste Management Rules, 2026, in Tamil Nadu, particularly focusing on Chennai. It highlights the critical need for 100% source segregation to improve waste processing, recycling, and reduce the burden on Urban Local Bodies (ULBs). Key issues include public resistance to waste-to-energy plants due to pollution concerns, health risks faced by ragpickers, and the need for robust infrastructure and manpower. The new rules introduce concepts like environmental compensation based on the 'polluter pays' principle and emphasize digital tracking and stakeholder responsibilities. Various cities in Tamil Nadu are grappling with compliance, infrastructure gaps, and the need for behavioral modification campaigns.

Tamil Nadu’s elusive Bengal foxes and their shrinking space

The Bengal fox (Vulpes bengalensis), once common in south Indian grasslands, is now elusive due to habitat loss from agricultural expansion, urbanisation, road kills, and persecution during rituals like 'fox jallikattu'. Despite being 'data-deficient' with little population data, conservationists and the Tamil Nadu Forest Department are undertaking surveys, awareness campaigns, and forming task forces, particularly through initiatives like the Salem Innovation Centre, to protect this 'edge species' whose habitats often fall outside protected areas. The species was initially listed as 'vermin' under the Wildlife Protection Act, 1972, but its numbers have significantly declined.

Italy and Balkans endure heatwave, U.S. also faces soaring temperatures

The article reports on a record-breaking heatwave impacting Italy, the Balkans, and parts of the U.S., causing hundreds of excess deaths, disrupting daily life, and increasing the risk of wildfires. It highlights the strain on healthcare systems and infrastructure, with scientists linking the extreme heat to human-caused climate change, making such events significantly more likely.

Landslide dams river in rain-battered Arunachal, warning for Assam downstream

A massive landslide triggered by heavy rainfall in Arunachal Pradesh blocked the Siji river, creating an artificial dam and posing a severe flash flood threat to downstream areas in both Arunachal Pradesh and Assam. The incident has caused significant damage to infrastructure, including roads and bridges, disrupted connectivity, and led to search operations for missing persons. The Border Roads Organisation (BRO) has been instrumental in restoring critical road links in the affected regions.

Claims about sugarcane juice directly mixed with petrol, car engine absorbing water because of ethanol “misleading, unsubstantiated”: Petroleum Ministry

The Union Petroleum Ministry has refuted "misleading" and "unsubstantiated" social media claims regarding ethanol-blended petrol. It clarified that ethanol for fuel blending is produced through established industrial processes (fermentation from feedstocks like molasses, broken rice, and maize), not by directly mixing sugarcane juice with petrol. The Ministry also stated that modern vehicles are equipped with safeguards to prevent water entry into fuel tanks, countering claims about ethanol's hygroscopic nature causing engine issues. It emphasized that higher blending levels are implemented only after rigorous technical evaluation and consultation with automobile manufacturers and other stakeholders.

Biochar offers a way to turn India’s farm smoke into ‘black gold’

The article highlights India's agricultural paradox of burning biomass, leading to air pollution and soil degradation, while vast lands suffer from low soil organic carbon. It proposes biochar, made from agricultural waste in low-oxygen conditions, as a carbon-negative solution. Biochar improves soil health, water retention, and crop productivity, while sequestering carbon. The piece advocates for integrating biochar into sustainable farming initiatives, leveraging carbon credit markets for economic incentives, and expanding its feedstock to include urban organic waste, aligning with circular economy principles for a resilient agricultural future and global climate mitigation.

New species of wild brinjal discovered in the Andamans

A new species of wild brinjal, Solanum pandeyi, has been discovered in the evergreen forests of Middle Andaman by a scientist from the Botanical Survey of India (BSI). The plant, locally known as wild orange eggplant, is used by the indigenous Great Andamanese tribe for food and medicinal purposes, particularly for treating tooth infections. Phylogenetic analysis confirmed its identity, and it is recognized for its potential as a genetic resource for developing high-yielding, disease-resistant brinjal varieties. The species' conservation status is currently assessed as Data Deficient, and the Andaman group of islands is highlighted as a significant biological hotspot.

Insuring the informal worker against the heat

The article discusses the emergence of 'parametric' heat-insurance products for informal workers in India, where payouts are triggered automatically when temperatures cross a pre-set threshold. It highlights initiatives by non-profits like Jan Sahas and SEWA, in partnership with insurance companies and CSR arms, to provide financial relief to vulnerable workers against climate-induced heatwaves. The piece also touches upon the challenges of funding such schemes, the behavioral impact on workers, and the broader context of climate change predictions by IMD and WMO.

The human cost of a deadly weed killer: banning of paraqua in Telangana

The article highlights the severe human cost of paraquat, a highly toxic weed killer, through a personal account of poisoning and the subsequent ban imposed by Telangana, Kerala, Odisha, and Andhra Pradesh. It delves into the regulatory challenges in India, including the limitations of the Insecticides Act, 1968, the lack of a central ban, and India's stance on the Rotterdam Convention. The piece also discusses the economic reasons for paraquat's widespread use in agriculture, the lobbying efforts by doctors and activists for a nationwide ban, and the difficulties in enforcing state-level prohibitions due to online sales and industry resistance.

Trump announces $700 million funding for coal plants, energy infrastructure

U.S. President Donald Trump announced $700 million in funding for coal plants, mines, and an export terminal, utilizing the Cold War-era Defence Production Act. This initiative aims to support the coal industry, keep existing facilities open, and build new ones, despite coal being the highest emitter of greenhouse gases. The move includes redirecting funds from climate change projects and follows previous actions to roll back environmental regulations and increase fossil fuel use, making the U.S. an outlier in global coal consumption trends. The UN has warned about rising global temperatures primarily driven by fossil fuels.
