Non-metros contributing 70% of our sales: BlueStar MD

India experienced extreme weather events on 88% of days in 2024, in one or more parts of the country, as per data by Centre for Science and Environment and Down To Earth. Between 1993 and 2022, India lost about $180 billion to severe heat and rains, the Climate Risk Index 2025 report said. This climate change, essentially the extreme summer, has also been causing shortage in gig workers for quick commerce players like Zepto, Zomato, Swiggy among others. Bengaluru: The aspirational middle class from tier 3,4 and 5 cities are the new consumers for home appliances company, BlueStar, which are contributing 70% of its sales, Managing Director B Thiragarajan told DH in an interview. “We saw almost 70% of the sales in scal year 2025, as there is a penetration level and good amount of disposable income.,” he said. India has been witnessing a rising demand for consumer goods, including electronics from non-metros as discretionary spending continues to rise. However, 2025 saw a distorted summer with early rain spells and erratic dampening the sales for consumer electronics companies. BlueStar, as the country’s second largest player in airconditioning, witnessed a degrowth of 25% in nancial year 2024-25 (FY25) as compared to the previous year when it saw 57% growth. The cooler than usual summer has hit the sales of several companies including talcum, ice cream, soft drink among others. The unusual weather has emerged as a new threat to India’s 1.4 billion-strong market lately. Despite this, the rm believes that the rest of the year will make up for the degrowth, particularly the festive season. “If the summer has failed a full year, the growth will be there because subsequent seasons do well,” he added. Additionally, the company is investing in customer experience especially as quick commerce has been picking up pace. The Mumbai-headquartered rm has been beeng up delivery on quick commerce platforms, given that it’s increasingly becoming a way of life, especially in metros. For now, Blue Star had to slash production by as much as 25% between April and June, as it saw less buyers. While workforce remains an issue for the home appliances rm with respect to demand, conforming to Bureau of Indian Standards (BIS) has created hurdles in the supply chain because of testing. BlueStar also sells commercial ACs, however, the market size continues to be very small. Presently, the commercial segment is one-tenth of the of the country, as per data by Centre for Science and Environment and Down To Earth

Severe rainfall alert in Uttarakhand as cloudburst kills 9 in Uttarkashi landslide

“Unregulated construction along riverbanks and steep slopes turns every cloudburst into a potential death sentence,” said Dr. Sunita Narain, Director General of the Centre for Science and Environment. “We’re building in places that nature never intended for permanent human habitation.” In the fragile hours before sunrise on Sunday, a sudden cloudburst above the Silla village in Uttarkashi district set off a deadly cascade of destruction. The torrential downpour triggered flash floods and a massive landslide that slammed into a construction site near the Yamunotri pilgrimage route, sweeping away tents and laborers in its violent descent. By Monday morning, the grim toll had come into sharper focus: two bodies recovered, seven more feared dead, and a state left shaken under a renewed severe rainfall alert. The victims were laborers and staff stationed at a campsite established for an upcoming resort project. Their lives, like the tin sheds they sheltered in, were torn apart in seconds. According to The Times of India, State Disaster Response Force (SDRF) teams, alongside local police and fire services, waded through slush and shattered debris to recover remains and search for survivors. “This was no ordinary rain. It was a brutal cloudburst that came down with ferocity,” said Uttarkashi District Magistrate Meharban Singh Bisht. “9 feared dead in pre-dawn flash flood at Uttarkashi resort construction site.” The cloudburst struck at approximately 2:45 a.m., as most of the workers were asleep in temporary shelters near the under-construction Yamunotri Bhawan. Located roughly 4 kilometers from the Yamunotri temple, the site is nestled in a region long vulnerable to cloudbursts and glacial runoff. Char Dham yatra suspended then restored The disaster forced the temporary suspension of the Char Dham yatra, one of India’s most sacred pilgrimages. Authorities closed the Barkot-Yamunotri road for over 24 hours, citing debris blockages and treacherous terrain. The route was reopened Monday afternoon after emergency crews cleared key chokepoints. “Safety of pilgrims is our top priority. We urge travelers to avoid the route during night hours and heed all weather advisories,” said a senior official from the Uttarakhand Tourism Department. “Uttarakhand cloudburst: 24-hour ban on Char Dham lifted.” Despite the restoration of road access, authorities have kept the severe rainfall alert in force for Uttarkashi, Chamoli, Rudraprayag, and Pithoragarh districts. The India Meteorological Department (IMD) warned of more heavy precipitation, thunderstorms, and localized flooding through Wednesday. Rising risk under changing skies This latest incident has reignited concern over the climate vulnerability of Uttarakhand, a state prone to flash floods, landslides, and seismic instability. Experts have long warned that rapid infrastructure development along sensitive Himalayan slopes is compounding the risk of catastrophic weather events. “Unregulated construction along riverbanks and steep slopes turns every cloudburst into a potential death sentence,” said Dr. Sunita Narain, Director General of the Centre for Science and Environment. “We’re building in places that nature never intended for permanent human habitation.” In February this year, a similar cloudburst in Joshimath led to widespread panic, displacing over 1,000 people. Now, with monsoon rains intensifying and glacial melt increasing due to global warming, the warnings have turned into regular realities. “Two killed, seven feared dead after landslide triggered by cloudburst.”

Yamuna near Taj Mahal heavily polluted with Microplastics, CSE study warns

A recent study by the Centre for Science and Environment (CSE) has found alarming concentrations of microplastic pollution in a 12-kilometre stretch of the Yamuna riverbed near the Taj Mahal. Among four sites studied, this section showed the highest sediment contamination, with 800 microplastic particles per kilogram, significantly higher than Poiya Ghat (480 mps), Parvathi Ghat, and Balkeshwar Ghat (600 mps). The main sources were identified as runoff from cloth-washing, plastic packaging, tyre wear, and fabric waste. Textile fibres constituted 57 per cent of detected particles, followed by fragments from packaging at 36 per cent. Black particles, often linked to tyre wear, made up 27 per cent of the total, with yellow microplastics forming 21 per cent. Toxic fibre and tyre particles dominate sediment pollution The study began in 2024 and included sampling of both surface water and sediment. Although there are no current legal limits for microplastics in India, the CSE flagged the findings as well above levels recorded in other rivers, including the Ganga, where sediment samples from Bengal had shown 428 mps. The report was shared at the Anil Agarwal Environment Training Institute in Rajasthan and has been submitted to the Union Ministry of Environment, Forest and Climate Change.

Delhi govt’s new anti-pollution plan lacks integrated approach: Expert

Plan unveiled for the world’s most polluted city could do with more technology and better air quality monitoring, says CSE’s Shambhavi Shukla The Delhi government’s Air Pollution Mitigation Plan 2025, announced this month, is promising but lacks an integrated comprehensive approach. There are many good things about the new plan to counter pollution, but a far bigger effort is needed,” Shambhavi Shukla of the Centre for Science and Environment (CSE) told this reporter. What Shukla said Recognising that vehicular emission was one of the bigger pollutants, BJP's Delhi government said that only BS-VI vehicles, CNG vehicles and electric vehicles will be allowed entry into the Union territory after November 1, 2025. This feature will not apply to vehicles already registered in Delhi and would apply to commercial vehicles – large medium and heavy good vehicles.

Yamuna stretch near Taj Mahal chokes on microplastics, study finds

Lucknow: A new study has uncovered dangerously high levels of microplastic pollution in the Yamuna riverbed near the iconic Taj Mahal, raising red flags for both environmental and public health. The findings, released by the Centre for Science and Environment (CSE), reveal that a 12-kilometre stretch of the river carries the heaviest load of microplastics among four locations surveyed along the Yamuna. The study, which began in 2024, sampled sediment and surface water from Poiya Ghat, Parvathi Ghat, Hathi Ghat, and the Taj Mahal stretch. The sediment collected near the Taj Mahal contained a staggering 800 microplastic particles (mps) per kilogram — far higher than the 480 to 600 mps recorded at the other sites. While Hathi Ghat reported the highest microplastic concentration in surface water (46 mps per cubic metre) due to intensive cloth-washing activities and wastewater discharge, the Taj Mahal stretch followed with 17 mps per cubic metre, making it the second-most polluted in terms of water contamination. The data was presented at the Anil Agarwal Environment Training Institute in Nimli, Rajasthan, and has since been forwarded to the Union Ministry of Environment, Forest and Climate Change.

Delhi: Nehru Park set to host 150 air purifiers in anti-pollution plan

“The best example is our two Delhi smog towers at Anand Vihar and Connaught Place. As of now, we have not seen any evidence to suggest how air purifiers outside can clean up air in an effective radius in the city,” said Anumita Roychowdhury, executive director of research and advocacy at the Centre for Science and Environment. The Delhi government will install 150 outdoor air purifiers at Nehru Park in a pilot project aimed at creating the city’s first “clean air zone,” environment minister Manjinder Singh Sirsa said, outlining a plan that experts called unviable and impractical. Sirsa said the devices, upto nine-feet-tall PM 2.5 particulate matter filters, will be spread across the 85-acre park and maintain “good” air quality even during peak pollution periods. “This initiative is part of the government’s efforts to improve air quality in the city. It will be a first-of-its-kind pilot project in the country to improve air quality at a public park,” Sirsa told HT. The announcement comes as Delhi has grappled for years with hazardous air pollution levels that peak in the transition to winter. It follows the closure of two expensive smog towers that authorities deemed ineffective, after the then Aam Aadmi Party government touted them as first-of-its-kind solutions to the city’s bad air crisis. In 2023, the Delhi Pollution Control Committee called the Connaught Place smog tower experiment ineffective in improving outdoor air quality. The new project will be carried out through a corporate social responsibility partnership with private firm Umeandus, which has tested the technology at four locations including Anand Vihar, a Jangpura petrol pump, New Moti Bagh and outside the Taj Ambassador hotel. Each purifier will cover approximately 600 square metres and requires approval from the New Delhi Municipal Council before installation can begin, Sirsa said. The devices are easy to install and occupy minimal space, according to the minister. Officials said each machine costs around ₹5 lakh and the project will be funded through Corporate Social Responsibility (CSR). Experts questioned the viability of outdoor air purification technology, pointing to the failure of previous initiatives. “The best example is our two Delhi smog towers at Anand Vihar and Connaught Place. As of now, we have not seen any evidence to suggest how air purifiers outside can clean up air in an effective radius in the city,” said Anumita Roychowdhury, executive director of research and advocacy at the Centre for Science and Environment.

Catapults to Cameras: A Simplistic Lens on Complex Conservation Challenges in India

Sunita Narain, director general of New Delhi-based Centre for Science and Environment (CSE), was the chairperson of the task force. She was also my editor at the Down To Earth magazine where I was a reporter. Storytelling from the heartlands of our country is extremely complex. The narratives have shades of grey and defy the simplistic evil vs virtuous stands. There are Waghoba shrines in forest areas dedicated to tigers/leopards that are worshipped by the local communities; there are also festivals, like the Sikari Utsav, which celebrate hunting. My first encounter with this paradox was 20 years ago, in 2005, at the Melghat Tiger Reserve in the Vidarbha region of Maharashtra. It was when the Ministry of Environment and Forests (Project Tiger) had set up a task force to review the management of tiger reserves in the country. Battlelines had been forcibly drawn between the big cat and the local forest communities that were being displaced for the conservation of the tiger. Sunita Narain, director general of New Delhi-based Centre for Science and Environment (CSE), was the chairperson of the task force. She was also my editor at the Down To Earth magazine where I was a reporter. The situation was tense at Melghat where I visited several villages bordering the core area and within the buffer zone of the tiger reserve. Churni, Pastalai, and Vairath villages were slated for an immediate relocation and rehabilitation. The Gawli community, traditionally cattle rearers and milk supplies inhabited Churni and Vairath, and it was the Korku tribe that lived in Pastalia; most of them practised subsistence farming. These communities claimed they had lived in the forest lands alongside wild animals for generations. The cattle belonging to the Gawlis grazed in the jungle. The villagers were being evicted from the forests to save the tiger, whom they worshipped as waghoba. “Till now we used to live with the bagh [tiger] and did not disturb it. But now if I see a bagh, I will shoot it down because it is forcing us to turn homeless,” an elderly member of the Gawli community from Vairath told me. The government had made alternative arrangements for these villagers but most were unhappy with the rehabilitation package and the ‘poor’ quality of land that was allotted to them. Villagers of Vairath were allotted land in a river! I remember struggling to write that report. It was a complex situation. Should one ‘side’ with the government and conservationists who wanted the forest-dwelling communities out of the forest to protect a flagship species. Or, should it be about the rights of the Adivasis and forest dwelling communities who have lived there for generations and have known no other home? Their lives and livelihoods directly depended on the forests. My editor Narain, sensing my conflict, advised me, “Just write what you found out and what the villagers and forest officials told you. Conservation in our country is a complex matter and there are no easy answers and simple solutions.” These words have stayed with me and guided me as I tread the path of an environmental journalist. Every new story that I have reported on, has presented another complex facet of conservation in the country. One of them is about the hunting festival in West Bengal held during the dry season (March-May) in the districts of Jhargram, Paschim Medinipur, Bankura, Purulia, and Birbhum. As part of this annual hunting festival, thousands of men and boys, armed with bows, arrows and catapults, enter the forests to hunt wild boars and wild hares. In her film Catapults to Cameras, a 40-minute film produced by RoundGlass Sustain, director Ashwika Kapur, a Kolkata-born wildlife filmmaker says, “It is an unnerving sight. Villagers return from the forest carrying hoards of dead wild animals and birds. Anything they find moving or crawling in the forest, they kill it. It is gory and shocking because such hunting is banned.” Catapults to Cameras was recently screened at the National Centre for Performing Arts (NCPA), Mumbai. Post screening, the filmmaker joined the audience virtually for an interactive session. RoundGlass Sustain is a not-for-profit initiative that tells stories of India's natural world to document science, create awareness, and support conservation. Kapur said that the film sets out on a deeply personal quest to uncover the roots of an illegal wildlife hunting festival in the forests of her home state, West Bengal. She described the annual hunting festival as an illegal blood sport, where thousands of protected animals are massacred.

Ammonium sulfate contributes to one-third of Faridabad’s PM2.5 pollution

Gurgaon: Ammonium sulfate is responsible for a staggering one-third of Faridabad's PM2.5 concentration, according to a study by the Centre for Research on Energy and Clean Air (CREA), which underlined the need for National Clean Air Programme (NCAP) to take a closer look at the secondary pollutant. Ammonium sulfate forms insidiously in the atmosphere through chemical reactions between sulfur dioxide (SO₂) and ammonia (NH₃). CREA's analysis reveals that this pollutant, averaging 19.76 µg/m³ out of a total PM2.5 level of 58.28 µg/m³ of Faridabad mean data, is prevalent across nearly all NCAP cities, irrespective of their proximity to major emission sources, therefore showing the need for a unified national strategy. NCAP primarily targets PM10. However, PM2.5 poses great danger to human health, its smaller size allowing it to penetrate deep into the lungs and enter the bloodstream. The health impacts are severe, ranging from increased risk of premature death, nonfatal heart attacks, irregular heartbeat, aggravated asthma, decreased lung function, and even lung cancer. Faridabad's designation as the sole ‘non-attainment' city in Haryana under the NCAP highlights its consistent failure to meet National Ambient Air Quality Standards (NAAQS). These precursor gases are commonly spewed from coal-fired thermal power plants, agricultural fertiliser use and livestock waste — sources that often extend far beyond city limits. The new study further highlights the complex challenges cities are facing. The transboundary nature of ammonium sulfate pollution means that local emission controls, while necessary, are insufficient on their own. A comprehensive, national approach is imperative to tackle this pervasive and deadly component of India's air pollution crisis, ensuring cleaner air for all its citizens. "To make real progress, NCAP must evolve to include targeted measures for reducing secondary pollutants," said Manoj Kumar, an analyst at CREA, adding that city and state-level clean air action plans must explicitly tackle major sources of precursor gases. Kumar also emphasised the importance of source-specific strategies, such as installing flue-gas desulfurisation units in coal-fired power plants to reduce sulfur dioxide (SO2) emissions, promoting efficient fertiliser management to curb ammonia release and ensuring strict compliance with existing emission norms across all polluting sectors. The study serves as a wake-up call for policymakers to recalibrate India's clean air strategy, shifting focus from just visible dust to invisible but deadly chemical reactions that are silently poisoning the air. "In addition to ammonium sulfate, other secondary pollutants like ammonium nitrate also contribute significantly to PM2.5 mass. In fact, secondary particles can account for up to 50% of total PM2.5 mass, according to an IIT study which triggered our analysis. The IIT study found that even beyond 200km of a thermal plant, sulfate concentrations were found," he added. Experts also pointed out that the air pollution crisis in cities like Faridabad might not improve until the govt takes all parameters into account. "The dominance of ammonium sulfate in Faridabad's PM2.5 profile is a stark reminder that India's air pollution crisis is no longer just about visible smoke or dust. It's about invisible chemical transformations driven by coal and fertiliser emissions. Without a strategic shift to tackle secondary pollutants and precursor gases, cities like Faridabad will continue to choke under a haze that knows no boundaries," said Shubhansh Tiwari, a research associate at Centre for Science and Environment (CSE). "We recognise the growing complexity of air pollution in Faridabad, especially the role of secondary pollutants like ammonium sulfate. We are factoring in results of the recent source apportionment study to expand our monitoring network to better understand and tackle these emerging challenges," said an HSPCB official. NCAP is an initiative launched by the Ministry of Environment, Forest and Climate Change (MoEFCC) in Jan 2019. Its primary goal is to improve air quality in 131 cities across India, known as non-attainment cities and million-plus cities. The programme aims at achieving a 20-30% reduction in particulate matter concentrations by 2024, using 2017 as the base year. Recently, the target was updated to a 40% reduction by 2026.

Centre’s 2-Way Approach To Tackle Lightning, Urban Flooding

According to a study conducted by the Centre for Science and Environment, at least 162 people were killed by lightning strikes across 12 Indian states between March and April 2025, which is a staggering 184 per cent rise compared with 57 fatalities recorded last year between March and April. Admitting that lightning strikes, heatwaves and urban flooding are major cause of concern for India, the National Disaster Management Authority (NDMA) has adopted a two-way approach to counter such natural calamities. According to Sanjeev Kumar Jindal, additional secretary (disaster management) in the Home Ministry, the NDMA has identified more than 50 sensitive districts in 10 states which are prone to lightning strikes and heat waves and accordingly a national programme has been initiated to mitigate the impact of such natural calamities. The states, including Andhra Pradesh, Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Maharashtra, Meghalaya, Odisha, Uttar Pradesh and West Bengal, severely suffer due to high frequency of lightning, said Jindal. The national programme to mitigate the impact of natural calamities focuses on awareness campaigns, community-based initiatives and infrastructure improvements to reduce casualties and economic losses. “The government has sanctioned a mitigation project on lightning safety at a total outlay of Rs 186.78 crore,” said Jindal. The programme will be implemented through the NDMA and State Disaster Management Authorities (SDMAs). The Centre has also asked the state government to ensure that all emergency operation centres (EOC) are active at the district level. The state authorities have been suggested to continuously monitor the India Disaster Resource Network (IDRC) portal. As per data provided by NDMA, more than 2,500 people die due to thunderstorms and lightning every year in India. According to a study conducted by the Centre for Science and Environment, at least 162 people were killed by lightning strikes across 12 Indian states between March and April 2025, which is a staggering 184 per cent rise compared with 57 fatalities recorded last year between March and April. Bihar is the worst-affected state, recording 99 lightning deaths between March and mid-April 2025, according to the state’s disaster management authorities. Multiple recent studies based on short-term data indicate that Kerala is also one of the hotspots for lightning strikes, which peaks from March to May with a secondary peak from September to November. However, as per data provided by the Ministry of Earth Science, there is significant inter-annual variability of convective activity over Kerala and other parts of the Indian region, which is driven by the multi-year variability of various global factors. Statistics compiled by the Ministry of Earth Science state, 730 people died due to heatwaves in India in 2022 with Punjab and Uttar Pradesh registering the maximum deaths of 130 each followed by Maharashtra 90. Similarly, the NDMA has also initiated a plan to implement urban flood risk mitigation projects in 11 more cities, involving a mix of structural and non-structural measures. “This is in addition to the Rs 3075.65 crore sanctioned under Urban Flood Risk Mitigation Projects for seven cities including Ahmedabad, Bengaluru, Chennai, Hyderabad, Kolkata, Mumbai and Pune,” said Jindal. Jindal said that the Central Government has taken several initiatives to ensure effective mitigation measures in the country to prevent any extensive loss of life and property during disasters by strengthening the disaster risk reduction system in India. These projects aim to address the increasing threat of urban flooding, exacerbated by climate change and rapid urbanisation, by improving drainage, increasing water storage capacity and implementing better urban planning and regulations. The northeastern states including Assam and Arunachal Pradesh registered the maximum casualties due to urban flooding this year following the death of at least 46 people. Significantly, the government has also started implementing National GLOF Risk Management Programme with a total financial outlay of Rs 150 crore for its implementation in four states namely Arunachal Pradesh, Himachal Pradesh, Sikkim and Uttarakhand. Talking to ETV Bharat, former member of NDMA Brigadier BK Khanna hailed the initiative adopted by the Centre. “The initiatives are most welcome. However, proper implementation of such initiatives need massive awareness drive,” said Brigadier Khanna, As far as urban flooding is concerned, according to Brigadier Khanna, along with an awareness drive, advance alert is also very much necessary. “Urban flooding is mainly caused by excess rain and poor drainage systems. Public participation to fight urban flooding is necessary. People should extend their support to the authorities to maintain a proper drainage system,” said Brigadier Khanna.

Study Finds Alarming Microplastic Pollution Near Taj Mahal Stretch Of Yamuna

A recent study conducted by Centre for Science and Environment (CSE), an environmental research body, has found that a 12-kilometre stretch of the Yamuna riverbed near the Taj Mahal contains the highest levels of toxic microplastic pollution among four sampled locations along the river. The research, which began in 2024, collected data from surface water and sediment at four sites: Poiya Ghat, Parvathi Ghat, Hathi Ghat, and the stretch near the Taj Mahal. The sediment sample from the Taj Mahal site showed a concentration of 800 microplastic particles (mps) per kilogram — the highest among the sites studied. The other sites showed significantly lower levels, ranging from 480mps to 600mps. The report, which was cited during a meeting at the Anil Agarwal Environment Training Institute — an education and training initiative of the CSE — at Nimli in Rajasthan. The findings point to runoff from laundry activities, discarded fabric fragments, plastic packaging, and tyre degradation as primary sources of contamination. Textile fibres alone accounted for 57% of the microplastics detected in sediment, followed by fragments from packaging materials (36%). The most common colour observed was black — often linked to tyre particles — making up 27% of the samples, followed by yellow at 21%. In terms of surface water pollution, the Taj Mahal stretch recorded the second-highest concentration at 17mps per cubic metre. Hathi Ghat showed the highest contamination in water, at 46mps, attributed to nearby large-scale cloth-washing activities and wastewater discharge from surrounding drains. The study, has been shared with the Union Ministry of Environment, Forest and Climate Change. Although India currently lacks legal thresholds for microplastic concentration, researchers noted that the levels observed in the Yamuna — particularly near the Taj Mahal — were significantly higher than in other stretches of the river or even in the Ganga, where a separate study found 428mps per kilogram in sediment samples from Bengal. Experts warn of serious health implications. Microplastics, which range from 1 nanometre to 5 millimetres in size, can enter the human body through water or food and are capable of infiltrating organs, crossing the placenta and blood-brain barrier. Once inside the body, they may cause inflammation, vascular issues, and carry toxic chemicals or pathogens into the system. The UNDP in its report suggests that these compounds are linked to serious health issues such as endocrine disruption, weight gain, insulin resistance, decreased reproductive health, and cancer. Given the reliance on the Yamuna for drinking water and fishing in the region, the findings have raised concerns about public health and ecological safety. Further assessments of microplastic levels in other rivers are expected in the near future.

Alarm over microplastic level in Yamuna near Taj Mahal, study flags severe pollution

A 12km stretch of the Yamuna riverbed near the Taj Mahal has the highest concentration of highly toxic microplastics compared to the other three segments sampled in a study conducted by environmental think tank Centre for Science and Environment (CSE). The study has identified runoff water from washed clothes, small pieces of fabric, plastic packaging materials and tyres as major sources of microplastic pollution. Microplastics are smaller plastic particles ranging between 1 nanometre, which is at least 80,000 times thinner than a hair follicle, and 5mm. They have the potential to trigger a range of health issues with long-term exposure and cause significant ecological hazards. The report, which was cited during a meeting at the Anil Agarwal Environment Training Institute — an education and training initiative of the CSE — at Nimli in Rajasthan on Thursday, has also been shared with the Union ministry of environment, forest and climate change, a key researcher associated with the study said. “Our study, which has been ongoing since 2024, was undertaken at four points in the Yamuna — Poiya Ghat, Parvathi Ghat, Hathi Ghat and the Taj Mahal — both at surface water level and sediments. We found that microplastic concentration was highest in the river bed close to the Taj Mahal — 800 microplastics (mps) per kilogram of sediment,” said Siddharth Singh, the deputy programme manager of the municipal solid waste unit at the CSE. Singh said that though there was no legally permissible limit on microplastics in the country, its concentration in the Yamuna near the Taj Mahal was significantly high compared with other stretches of the river and other major rivers of the country. The study shows that microplastic concentrations at the other three points in the Yamuna were much less, ranging between 480mps at Poiya Ghat and 600mps at Balkeshwar Ghat. According to the study, textile fibres were the major source of microplastics (at 57 per cent) in the sediments, followed by fragments from plastic packaging (36 per cent). In terms of colour of microplastics, black, mainly sourced from tyres, dominates at 27 per cent followed by yellow at 21 per cent. As far as surface water microplastic pollution is concerned, the stretch of the Yamuna near the Taj Mahal has the second-highest concentration of the pollutants — 17mps per cubic metre of water— among the four sites studied. The pollution was highest at Hathi Ghat with 46mps because of its proximity to large-scale cloth-washing points and major nullahs draining wastewater into the river. “It’s a problem everywhere. Though the state pollution control board has not carried out any study so far, the report of another study shows that the microplastic concentration in the sediments in the Ganga in Bengal is 428mps per kilogram. We are planning to assess the microplastic level soon in various rivers,” said Kalyan Rudra, chairman of the pollution control board in Bengal and a river expert. “The public health implications of the findings are huge. Besides having a direct impact, microplastics act as a vehicle for toxic chemicals and even pathogens to enter our system. The findings near the Taj Mahal assume enormous importance also from the standpoint of drinking water supplies from the Yamuna and the fishing being done in the region,” Arunabha Majumdar, a retired director of the All India Institute of Hygiene & Public Health, said. According to experts, microplastics can infiltrate organs and cross the blood-brain barrier and placenta, leading to inflammation and vascular blockages, among other health complications.

Bonn: Breakthrough as just transition priorities tabled in UN climate process

Avantika Goswami, Programme Manager, Climate Change, Centre for Science and Environment (CSE), India: “We do not see appetite to uphold multilateralism from developed countries, and Bonn made that clear. The refusal to dive deeper into Article 9.1 and hear out concerns from developing countries about unilateral trade measures, symbolise the imbalance of power that persists in this space. While civil society is driving momentum on issues like just transition, all other spaces remain paralysed by inequity, and refusal of the Global North to support, fund and enable climate action in the rest of the world in line with its historical duty.” German State Secretary for Climate, Jochen Flasbarth, described the Bonn climate conference, a mid-year meeting of stakeholders, as an “important reality check.” Efforts to limit global warming must now be reflected in concrete new climate plans from around 200 countries, Flasbarth told dpa. “This is because in 2025, all countries will be required to submit these plans and outline how they will further reduce their climate-damaging emissions in line with the 1.5-degree limit by 2035,” he said. Some countries have already presented their strategies, while the EU and many others are still working on theirs, said Flasbarth. However, after two tense weeks of negotiations, breakthrough appears to have emerged in the SB62 climate talks in Bonn: civil society’s Just Transition priorities were officially tabled in the UN climate process, thanks to relentless pressure from social movements, workers, and frontline communities. According to observers, this vital step opens the door in the fight for transitions that put people first – ensuring climate action centres justice, dignity, and decent work, rather than enabling corporate greenwashing or elite control. But, beyond this opening, Bonn reportedly laid bare a system in crisis. Even as NATO leaders just 200km away pledged more than US$1 trillion a year in additional military spending, rich polluting countries showed up at the climate talks pleading poverty. The silence on war, genocide, and rising global inequality was deafening. Despite the escalating toll of climate impacts and injustice, the talks revealed a growing chasm between the urgent demands of communities on the frontlines of climate breakdown and the hollow, evasive language of a process struggling to retain relevance. Negotiations on adaptation were little more than a smokescreen. Developed nations dodged their financial obligations towards developing countries once again, and held the process hostage, preventing progress. The ghost of Baku seemed to haunt the talks, with developing countries facing fierce pushback when they united in their demand for a formal agenda item on the provision of climate finance by developed countries. “And it’s clear the so-called ‘Baku to Belém’ roadmap remains riddled with holes. Without new, additional and grant-based public finance from historical emitters, there will be no money to fund a real Just Transition, no closing of the ambition gap, and no hope of holding the line at 1.5°C. The COP30 Presidency and all parties must put a plan in place to address the critical issue of the provision of climate finance, or risk a blow up,” environment watchdog group, Climate Action Network International, submitted in a statement. As countries belatedly prepare their new climate action plans (Nationally Determined Contributions), one thing is clear: they will fall far short of what is needed. Despite this, there was a resounding silence around the ambition gap that is so clearly emerging. Countries that hold historic responsibility for the climate crisis continue to expand oil and gas exploration while pushing developing countries to shoulder the burden they themselves refuse to bear – both in cutting emissions and providing climate finance. It’s a double standard that deepens injustice and delays real action. Tasneem Essop, Executive Director of Climate Action Network International, said: “Enough is enough. While bombs get billions and polluters are increasing their record profits, Bonn has once again exposed a system rigged to protect polluters and profiteers – complicit in a global order that funds destruction but balks at paying for survival. “But even in this broken space, people’s power shone through. Due to the relentless pressure from civil society, the Just Transition fight finally made it into the formal process, laying the table for a win for workers, for communities, and for every person fighting to build a future rooted in dignity and hope. Decision-makers must come to Belém with the commitment to make this a reality. “As this process drifts further from the real world, it is grassroots movements that continue to lead the way – resisting delay, greenwashing, and false solutions with vision, urgency, and courage. From the streets of Bonn to the heart of Belém, the fight for climate justice is turning into a roar that cannot be ignored.” Caroline Brouillette, Executive Director, Climate Action Network Canada: “The world is facing a treacherous moment. Political headwinds and unfair economic rules are preventing the level of climate action we need. The UNFCCC feels increasingly disconnected from the real world. “Amidst the dark clouds of these existential challenges to the planet and to this process, there is a ray of sunshine: parties are finding common ground around a Just Transition. The text forwarded to Belem offers us a fighting chance to a COP30 outcome that truly connects workers, communities and Peoples with the Paris Agreement.” Amiera Sawas, Head of Research & Policy, Fossil Fuel Non-Proliferation Treaty Initiative: “As the Northern hemisphere suffers deadly heatwaves, UN climate talks remain frozen in an out-of-touch process. War and military spending escalated outside, while inside there was no discussion – and no finance. Civil society fought to bring negotiations into the real world, but geopolitics and the fossil fuel lobby kept derailing progress. Even successes, like the draft text for the ‘Just Transition Work Programme’ informed by workers and Indigenous Peoples, were nearly paralysed by fossil fuel interests at the end. “We are already at risk of breaching the 1.5 temperature limit, there’s no time for paralysis. There’s a real risk that the UN climate talks fail to address the crisis’s biggest drivers: coal, oil, and gas. We cannot afford any more failure; we must urgently do better. And we will – whether inside or outside the UN. Brazil is talking big, but its actions speak louder than words and its recent approval of new oil extraction in the Amazon is the worst possible signal.” Stela Herschmann, Climate Policy Specialist for Observatório do Clima (Brazil): “This is a party-driven process. What the Bonn meeting showed us is that the parties want to discuss public finance. Despite Brazil’s best intentions to streamline the agenda and make progress on other issues, it may not be possible to do so without including a conversation about public finance in the official COP30 agenda. “Brazil had three priorities for Bonn. One of them, Just Transition, saw good progress and produced a preparatory text with key asks from civil society organisations so this work programme can actually deliver justice to the people. The other two resemble Baku. The text on indicators for the global goal of adaptation advanced well but is being held until the last minute due to the discussion around finance and means of implementation. “The UAE dialogue on the implementation of the Global Stocktake, did not progress as much. We will leave Bonn with two similar documents because the parties could not agree on a single informal note, and we can expect to see the same disputes over the scope and modalities in Belém.” Mariana Paoli, Global Advocacy Lead, Christian Aid: “The Bonn climate talks have shown that there’s hangover from the chaotic ending at COP29 in Baku. Finance remains the elephant in the room. While negotiators circled around the issue in Boon, limited progress was made. We cannot afford another year of delay – COP30 must deliver where COP29 fell short. “There has been an over reliance on the illusion that private finance will solve the climate crisis. Its growing presence in these spaces is starting to resemble a Trojan horse. Public grants-based finance is essential to deliver climate action, decisions should be done based on the needs of communities and not profits and should be rooted in fairness and science.” Teresa Anderson, ActionAid International: “Rich countries’ continued refusal to put real climate finance on the table means that climate talks are facing uncertain times. For once, however, it’s not all bad news. Governments are starting to get excited about Just Transition, and shaping energy and food systems in a way that really works for workers, women, farmers and communities. “This comes at such a critical time, amid so much economic uncertainty, when many people feel they are being forced to choose between their immediate needs and a climate safe future. If approved at COP30, the Just Transition mechanism will deliver action on the ground, requiring and supporting governments to put people’s needs first and foremost at the start of every climate plan. This represents a major evolution in climate action, and the spark of hope that our planet urgently needs.” Nithi Nesadurai, Director & Regional Coordinator, CAN Southeast Asia: “The Bonn climate meeting took place within the backdrop of a continuing genocide in Gaza, a hot war and the NATO Summit. Interestingly, while developed countries blocked decisions on their financial obligations on all the major climate negotiating items, a short distance away in The Hague, NATO members readily agreed to increase their military budgets to 5 per cent of GDP. “Easily amounting to hundreds of billions of dollars, it shows finance is available, unlike what they implied in the Bonn negotiations. If not for the progress on the Just Transition Work Programme, which gives civil society a core issue to rally around on the road to Belem, this meeting offered little to get excited about on all other fronts. Nafkote Dabi, Climate Policy Lead, Oxfam International: “The Bonn conference exposes the stark injustice between rich and poor countries. The richest, primarily responsible for the climate crisis, are dodging their duty to provide public, grant-based finance for developing countries to adapt and rebuild. As warming spirals toward a catastrophic 3°C, urgent action is critical. Rich countries must own their climate debt and stop pushing private finance, that prioritises profit over people, as a solution. The Brazilian COP presidency must also step up and champion equity and justice in Belem.” Sanjay Vashist, Director, Climate Action Network South Asia: “Climate talks in Bonn have failed South Asia once again. While our communities face climate-induced floods, heatwaves, and hunger, wealthy nations dodge their obligations, offering empty words on adaptation and loss and damage finance. The refusal to put public finance on the table is a betrayal. As we pivot to COP30 in Belém, we demand not just promises, but delivery – real, predictable, and equitable finance. The era of evasion must end. The lives of millions in South Asia depend on it, however the UNFCCC process appears to have succumbed to fossil fuel lobbyists and private sector forces.” Romain Ioualalen, Global Policy lead at Oil Change International: “Bonn saw the Global North further retreat from its responsibilities to provide public finance for climate action, instead promoting fabricated narratives on private finance filling the gap – despite evidence the market-led approach is not delivering. On top of blocking finance, rich countries failed their homework on fossil fuels with four Global North countries responsible for 70% of projected oil and gas expansion, which made calls from developed parties to center the fossil fuel phaseout in the negotiations continue to ring hollow and hypocritical. An outcome on just transition in Belém is within reach and could provide momentum for centering justice in the transition.” Ife Kilimanjaro, U.S. Climate Action Network: “Bonn confirmed the UNFCCC feels dangerously out of touch with global crises – war, inequality, and a climate already past 1.5 degrees. The fight for public climate finance was an uphill battle; rich nations diverted responsibility, pushing risky private solutions that won’t close the ambition gap. Yet, a vital glimmer of hope emerged: civil society secured demands in the Just Transition text. This shows organised people can make progress even in disconnected spaces. For USCAN, it’s clear: we must keep bridging the gap between power and lived realities, demanding genuine accountability and justice.” Fernanda de Carvalho, WWF Global Climate and Energy Policy Lead: “The breakthrough we achieved in Dubai is at stake. Developed countries who should be leading the way, continue to explore for, and use fossil fuels while deforestation is on the rise. We need them to step up at the global level and commit to phasing out all fossil fuels, putting some much-needed momentum into the international climate talks. We also need strong measures to halt and reverse deforestation by 2030. We look to Belém as a political course-correction moment, and we count on the Brazilian Presidency and the political will of all countries to deliver that.” Avantika Goswami, Programme Manager, Climate Change, Centre for Science and Environment (CSE), India: “We do not see appetite to uphold multilateralism from developed countries, and Bonn made that clear. The refusal to dive deeper into Article 9.1 and hear out concerns from developing countries about unilateral trade measures, symbolise the imbalance of power that persists in this space. While civil society is driving momentum on issues like just transition, all other spaces remain paralysed by inequity, and refusal of the Global North to support, fund and enable climate action in the rest of the world in line with its historical duty.” Ann Harrison, Climate Justice Policy Adviser, Amnesty International: “Human rights references and protections were again sacrificed at the altar of consensus which drives down ambition. UNFCCC reform must be on the table, including greater protections for free speech and peaceful protest which were further restricted, particularly for actions protesting the genocide in Gaza and solidarity actions for imprisoned defenders. “Fossil fuel producers continue to undermine progress towards the full, fast, fair and funded fossil fuel phase out and just transition we need. And let’s be clear, providing adequate public, grants-based climate finance, especially for adaptation and loss and damage is also a human rights obligation for developed countries, and it must be massively scaled up to contribute towards climate justice.” Andreas Sieber, 350.org Associate Director of Global Policy and Campaigns: “Bonn was bogged down by political divisions and bruised by global tensions, with results that leave much to be desired. A serious injection of energy and urgency is required as we look ahead to COP30 in Belém. Negotiators must make progress on implementing the Global Stocktake, closing the ambition gap, and delivering the finance needed to turn ambition into action. “Civil society must hold the line on the agreement to triple renewables and phase out fossil fuels, and rich countries must course correct after Baku’s shortcomings. COP30 has much to make up for, and for it to be a success, the Presidency must lead with the integrity, diplomacy and flexibility this crisis demands.” Gaïa Febvre, Réseau Action Climat France, International Policy Lead: “As the Bonn climate talks come to a close, it is shocking to see France, once the proud ‘guardian’ of the Paris Agreement, actively blocking a more ambitious EU NDC. “What’s the point of hosting summits and delivering grand speeches if, behind closed doors, France stalls the very commitments needed to keep 1.5°C alive? The Paris Agreement doesn’t need more ceremony, it needs leadership. It needs a France that pushes the EU to step up, not one that defends the status quo or fossil interests. The window to act is closing. France must choose: will it honor the legacy of Paris, or betray it?” More than 5,000 delegates took part in the negotiations in Bonn. The city is home to the UN Climate Change Secretariat, which coordinates international climate policy. The annual talks are seen as a critical step in shaping the global climate agenda ahead of the main event in the Brazilian city of Belém in November, known as COP30.

Seeds of resilience: Inside India’s quiet revolution of community seed banks

On the International Day for Biological Diversity in May 2025, the farmers, researchers, and civil-society groups joined an online discussion hosted by the Centre for Science and Environment (CSE) to showcase India’s community seed banks. “While there is biodiversity all around us, what nourishes us is the biodiversity on our plates,” says Vibha Varshney, who heads the Biodiversity and Food programme at the CSE. She added, “These community seed banks hold the genetic wealth that can keep that plate full even when the climate turns hostile.” A counter narrative to agricultural uniformity CSE’s freshly released report, Climate-Resilient Seeds: The story of community seed banks in India, estimates that the country’s informal seed savers now steward at least 887 traditional varieties across seventy-one crop species, a figure compiled from twenty-two banks and two individual custodians in fifteen states. Karnataka alone accounts for 186 varieties, closely followed by Nagaland’s 156 and Odisha’s 152. “Diversity-based farming is not nostalgia; it is a real solution for a climate-risked world,” the report stresses. That insistence on diversity challenges a half-century of policy that privileged high-yielding, genetically narrow hybrids. CSE notes that sixty-five percent of India’s seed needs are still met by farmer-to-farmer exchange, yet these informal networks lack formal recognition even after the Protection of Plant Varieties and Farmers’ Rights Act ostensibly protected farmers’ rights to save and share seed. How do the seed banks work? Most banks now operate as webs of ten or so households connected by what farmers call the “five-kilo-take, ten-kilo-return” ethic. After every harvest, seed borrowers bring back double the quantity they received, ensuring constant renewal. Others, especially in tribal belts, rely on pure gifting; a few women’s cooperatives in Gujarat and Maharashtra sell a fraction of surplus seed at a small premium so the bank can buy steel drums or moisture metres. “Improvement doesn’t come just from infrastructure,” explains Sahaja Samrudha founder G. Krishna Prasad, adding, “It’s about creating trust, and that begins with recognising seed savers as ‘custodians of biodiversity.” Prasad’s collective in Karnataka curates more than seventy finger-millet lines. Four or five that excel in participatory variety trials enter contract multiplication; the rest are grown in tiny rows simply so they do not disappear. “Those sixty-odd lines are genetic wealth. Even if nobody wants them today, they might save us tomorrow,” he says. In the northeastern hills, the Chizami Women’s Seed Bank holds over 150 local rice and vegetable varieties. Its governing rules give widows and marginal farmers first pick of seed—a crucial buffer in a landscape where markets are distant and landslides frequent. Similar women-led systems anchor banks in Odisha, Gujarat and Madhya Pradesh. “Women are the primary custodians of selection and storage knowledge, and their leadership increases community engagement,” the report finds. Mini rice seed bank (Image: Gaurav Dhwaj Khadka) Mini rice seed bank (Image: Gaurav Dhwaj Khadka) Climate traits written in grain Walk through the seed jars, and India’s climate atlas comes alive. Deep-water rice such as Rakthasali and Kuttadan ride out week-long submergence; finger-millet landraces like Bhadaee withstand forty-degree heat; paunchhi rice bends rather than breaks in cyclonic winds; and bottle gourds cured with turmeric sprout in soils laced with tidal salt. “These seeds let farmers bounce back after a flood, a drought, or a pest wave,” Varshney says. “They are the first insurance payout—paid in grain, not rupees.” The human stories behind statistics Vijay Jardhari, patriarch of Uttarakhand’s forty-year-old Beej Bachao Andolan, likes to hold up a wooden box he calls the bijunda—a farmer’s personal seed chest. “The bijunda is insurance against hunger, inflation, and climate shocks,” he told participants. “A mountain farmer would die but never eat the seed meant for the next sowing.” Down in Maharashtra’s Western Ghats, forest-regeneration activist Bharat Mansata reminds visitors that his Vanvadi collective now harvests food from eighty forest species. “The government must realise that this is genetic wealth,” he says. “Tragically, it is often available to large buyers before it is accessible to small farmers.” Headwinds: money, policy, and climate extremes Yet all custodians report similar hurdles. Banks depend on NGO grants or goodwill sales; few can afford cold rooms. Heatwaves waver germination rates; erratic rains shrink multiplication harvests. Younger cultivators, seduced by glossy catalogues and credit-linked hybrid packets, dismiss landraces as “old-fashioned,” CSE researcher Shimali Chauhan warns. On the policy front, draft seed legislation that tightens certification rules could inadvertently criminalise informal exchange—contradicting farmers’ rights enshrined elsewhere. “Regulation supports hybrid production but gives neither subsidy nor lab access to those who keep traditional lines alive,” Prasad argues. What would it take to scale up? CSE’s report calls for a five-point agenda. It urges formal recognition of seed savers as biodiversity custodians; public grants for low-energy storage and on-farm viability testing; inclusion of traditional seed lots in schemes such as the National Food Security Mission; consumer education that links taste with diversity; and an open-source digital atlas that matches farmers who need seed with banks that hold it. “It’s not just about building storage spaces; it’s about creating resilient, people-centred ecosystems where knowledge and local stewardship are valued,” the report concludes.

The Belligerent Disorder

It’s been a surreal few months; my (our) world is spinning like a top and seems completely out of control. Nothing seems to make sense anymore. It is a strange time, and I say this particularly for the half-a-century people like me who grew up in the post-colonial era and witnessed a world order that was intensely inequitable but still seemed capable of reform. Maybe it was the age of innocence. But we had hope in the global rule of law, even if it was led by powerful global players; we believed that voices of reason would prevail. The UN had a role—even though the Security Council, then and now, was a body which mirrored an inequitable and unfair global power order—but it still stood with the right, against the wrong. There was something to hold on to; something to believe in.

Spotlight on funding for just transition at Bonn Meetings

Developed countries do not want to discuss that,” said Rudrath Avinashi, Programme Officer, Centre for Science and Environment. Divergences on key issues continued at the ongoing Bonn Climate Meetings, which act as a midway point before the annual climate conference (COP30) scheduled to take place in Belem, Brazil this November, slowing down progress on important issues. Embers glow at night as the Basin Fire burns in the Sierra National Forest in Fresno County, California, on June 26, 2024. (AFP) Embers glow at night as the Basin Fire burns in the Sierra National Forest in Fresno County, California, on June 26, 2024. (AFP) Developed and developing countries sparred over the provision of finance for adaptation and Just Transition Work Programme (JTWP) in the past couple of days. The Bonn meetings will close on June 26. HT reported on June 19 that India and several developing countries have expressed disappointment after a key climate finance discussion was excluded from the Bonn Climate Talks agenda, vowing to raise the issue at November’s COP30 summit in Brazil. The dispute centred on Article 9.1 of the Paris Agreement, which mandates that developed countries provide financial resources to assist developing nations with both mitigation and adaptation efforts including for energy transition. The exclusion of this discussion from the agenda led to a 30-hour delay before talks could begin. Consultations were taken up on article 9.1 again on Monday, in the context of Just Transition Work Programme. “Possibly the most heated segment of the day was the consultations by the Subsidiary Bodies’ Chairs with parties on the implementation of Paris Agreement Article 9.1 (developed countries’ provision of climate finance). Developing countries underscored the inadequacy of current levels of finance, lamenting mounting costs related to loss and damage and the debt burden caused by non-concessional loans,” reported the Earth Negotiations Bulletin of International Institute for Sustainable Development. The Like Minded Developing Countries which includes India, the Arab group of countries, African group, and others lamented developed countries’ lack of political will to implement their legal obligation under Paris Agreement Article 9.1 and UNFCCC Article 4.3 (provision of new and additional financial resources by developed countries). They supported a standalone item on Article 9.1 which was opposed by the EU, Environmental Integrity Group (developed country coalition), and Australia among others who pointed to existing finance-related agenda items that include consideration of Article 9.1, such as the Standing Committee on Finance, the Bulletin said. Developed countries also tried to block discussions on advancing the Just Transition Work Programme (JTWP) and finance consultations for it, according to observers. “The first week of informal consultations on the Just Transition Work Programme (JTWP)...began with numerous proposals from developing countries on actionable outcomes, amidst continuous attempts from developed countries to limit and block these proposals from advancing the work programme,” the Third World Network said in its bulletin. Developed countries placed more emphasis on having key high-level messages emerging from the dialogues as important outcomes from JTWP this year, and did not agree to any new institutional arrangement that would have additional financial implications, citing that discussion on any new institutional arrangement is premature, and Parties should wait until the review of the work programme in 2026, TWN, an independent non-profit international research and advocacy organisation involved in issues related to the Global South. India, speaking in its national capacity, on June 22 also raised its concerns in the use of language such as “global or international partnerships” as there is concern on whether one would consider these partnerships as “just” or not. (India was referring to the Just Energy Transition Partnerships – JETPs). It also raised concerns about the interpretations of just transitions by developed countries reflecting that “higher ambition is inherently just”. India said it would agree with it if it is rooted in historical responsibilities and equity as we all agreed that this work programme would be implemented in context of Article 2.2 of the PA. (Article 2.2 of the PA states that, “This Agreement will be implemented to reflect equity and the principle of CBDR- and respective capabilities, in the light of different national circumstances.”), the TWN reported. The JTWP was established at COP28 held in Dubai, but its scope and operationalisation are currently being negotiated at Bonn. The aim is to recommend a draft decision for adoption at COP30, to be held in Belém later this year. “The inclusion of unilateral trade measures (such as carbon border tax) under the JTWP is at the heart of the contestations. G77 and China, the largest developing countries bloc consisting of 134 countries want a discussion on UTM as such measures hinder their ability to eradicate poverty and develop sustainably. Developed countries do not want to discuss that,” said Rudrath Avinashi, Programme Officer, Centre for Science and Environment. “Additionally, the developed countries want the just transition pathways to be in line with 1.5 degree celsius global temperature goal. As a response, India on behalf of the like minded developing countries have argued that any targets which are global in nature should be rooted in the principle of common but differentiated responsibilities and respective capacities,” he added. “We are here at Bonn not to engage in a rudimentary exercise in negotiating text, but to enact a critical defence of lives and uphold the right of our countries to thrive,” said Anne Rasmussen, Lead ClimateNegotiator for the Alliance of Small Island States (AOSIS) in a statement on Tuesday. “Our world has not yet crossed the Paris Agreement 1.5-degree Celsius limit which refers to a 20-year average, but the most recent scientific reports underscore we are in a far worse danger zone than we previously thought. AOSIS calls on all countries to ensure we do not fail in our mission and destroy our citizens’ hopes of a sustainable future,” she added.

Under the blistering sun: Rising heat and the struggles of Chennai’s coastal communities

A study conducted by the Urban Lab at the Centre for Science and Environment (CSE), which analysed summer temperatures in India’s megacities since 2011, revealed that Chennai is the hottest among them, with an average summer heat index of 37.4°C, primarily due to elevated humidity levels. Anthony Ammal, a 43-year-old fisher from the coastal hamlet of Pulicat in Chennai, begins her day long before the sun scorches the concrete beneath her feet. Her mornings are occupied with preparing her two daughters for school and ensuring they are fed before she steps out. She then makes her way to the Pazhaverkadu fish market, where she labours for approximately 15 hours each day. As she settles into her allocated spot to clean the day’s fresh catch, the sun begins to blaze overhead, and the humid breeze offers little relief. Her sunburnt skin stings each time the salty sweat runs down her arms and face. The heat clings to the air like a heavy blanket, slowly draining her energy. Anthony Ammal removes the fine veins from the prawns with painstaking precision, even as every passing hour brings fresh pain to her aching legs, bent in a squat on the burning concrete. “The sunburn on my skin is the least of my concerns, as I have larger issues of making ends meet,” says Anthony Ammal. On the day I met Anthony Ammal at the Pazhaverkadu Market, the temperature had reached 37°C, but with the high humidity, it felt closer to 40°C. A study conducted by the Urban Lab at the Centre for Science and Environment (CSE), which analysed summer temperatures in India’s megacities since 2011, revealed that Chennai is the hottest among them, with an average summer heat index of 37.4°C, primarily due to elevated humidity levels. At this temperature, the wet bulb temperature can reach 32.49°C. When wet bulb temperatures surpass 30°C, they pose a potentially fatal threat to anyone working outdoors. Despite the harsh conditions, the fisheries sector, often called the ‘Sunrise Sector’, earned ₹60,523.89 crore in seafood exports in 2023–24. The Pazhaverkadu market alone makes up to ₹1 crore on most days. Still, many like Anthony Ammal, one of India’s 30 million who contribute significantly to the fishing economy, struggle to survive, earning a meagre ₹200 per day. As heat waves tighten their grip on Chennai, the rising temperatures pose serious threats to the city’s coastal communities, affecting their health and livelihoods.
