Heatwaves Intensify Ground-Level Ozone Pollution in India
Context:
A recent study published in the journal npj Clean Air by researchers from IIT Kharagpur and Kerala University of Fisheries and Ocean Studies found that heatwaves significantly increase ground-level ozone pollution in India, aggravating respiratory and cardiovascular health risks.
Key Findings
- The study analysed the relationship between heatwaves and surface ozone levels across India during 2004–2024, making it the first comprehensive nationwide assessment of heatwave-induced ozone pollution.
- Ground-level ozone is a harmful pollutant formed when nitrogen oxides (NOx), volatile organic compounds (VOCs), carbon monoxide, and methane react in sunlight. Higher temperatures accelerate these reactions.
- During heatwaves, surface ozone concentrations frequently reached 85–110 μg/m³, exceeding the WHO guideline of 70 μg/m³ across all regions.
- Major hotspots included north-west India, the Indo-Gangetic Plain, north-central India, north-east India, and the Western Himalayas, with ozone levels exceeding WHO limits by up to 115% in the Western Himalayas.
- The researchers identified 188 heatwave events between 2004 and 2024, with particularly severe episodes occurring in 2010, 2016, 2019, and 2024, often following strong El Niño years.
- In 2024, ozone exposure during heatwave periods was linked to approximately 26,500 deaths from Ischaemic Heart Disease (IHD) and Chronic Obstructive Pulmonary Disease (COPD).
- However, the additional mortality directly attributable to heatwave-driven ozone increases was estimated at around 830 deaths.
- Heatwaves in 2024 were particularly severe in north-west and north-central India, with temperatures exceeding 44°C and reaching a peak of 50.5°C at Churu, Rajasthan.
- The study highlights the growing threat of compound heat–air pollution events under climate change and recommends integrating ozone forecasting, air-quality advisories, and Heat Action Plans to better protect public health.
15-Million-Year-Old Marine Fossils Discovered in Odisha’s Mayurbhanj
Context:
Researchers have discovered Miocene-age fossils (around 15 million years old) in Odisha’s Mayurbhanj district, providing significant evidence of the region’s prehistoric marine past and indicating that present-day Baripada and surrounding areas were once submerged under a shallow sea.
Key Findings
- Fossil remains include shark teeth, shark vertebrae, fish bones, molluscan shells, and microscopic marine organisms.
- Preliminary studies suggest that shark remains account for nearly half of the fish fossils recovered from the site.
- The fossil assemblage indicates the existence of a rich marine ecosystem during the Miocene Epoch (23 million–5.3 million years ago).
- The discovery suggests that areas now located about 60 km inland from the present coastline were once part of a coastal marine basin.
- The findings provide evidence of marine transgression and regression and can help reconstruct ancient coastlines, understand sea-level fluctuations, and examine the impact of climatic and geological changeson eastern India.
- Researchers employed Remote Sensing and Geographic Information System (GIS)-based mapping along with field investigations to document fossil-bearing formations.
- Further studies may help explain the retreat of the sea from the region and establish geological correlations with similar fossil-bearing formations elsewhere in India.
- Experts have recommended granting Geo-Heritage Site status and establishing a fossil park or museum to promote conservation, research, education, and geo-tourism.
About Baripada Fossil Bed
- The Baripada Fossil Bed, locally known as “Asura Hadda” (Demon Bones), extends from Dera (Kuliana Block) to Pratappur (Badasahi Block) in Mayurbhanj district.
- Located along the Budhabalanga Riverregion, it is the only known site in Odisha where Miocene-age marine fossils have been discovered.
- The fossil-bearing sedimentary deposits preserve evidence of an ancient marine environment and provide valuable records of past ecological and geological conditions.
- The site serves as a natural laboratory for research in Paleontology, Stratigraphy, Sedimentology, Paleoecology, Paleoclimate, and Paleogeography.
- Owing to its scientific significance, the site has strong potential for development as a Geo-Heritage and Geo-Tourism destination.
World Day to Combat Desertification and Drought 2026
Context:
World Day to Combat Desertification and Drought is observed annually on 17 June to raise awareness about desertification, land degradation, drought, and the need for international cooperation to promote sustainable land management.
About the World Day to Combat Desertification and Drought

- The United Nations General Assembly proclaimed 17 June as the World Day to Combat Desertification and Drought through a resolution in 1994, following the adoption of the United Nations Convention to Combat Desertification (UNCCD).
- The day highlights the global challenge of desertification and drought, which affect all regions of the world and require coordinated international action.
- The 2026 theme, “Rangelands: Recognize. Respect. Restore.”, focuses on the importance of rangelands, which cover more than half of the Earth’s land surface and support nearly two billion people, including pastoralists and Indigenous communities.
- Rangelands play a crucial role in food security, biodiversity conservation, water regulation, and climate resilience.
- The theme aligns with the International Year of Rangelands and Pastoralists (2026) and calls for greater recognition of the ecological, economic, and cultural value of these ecosystems.
- However, up to 50% of global rangelands are degraded or at risk, threatening livelihoods, biodiversity, and ecosystem services.
Govt Strengthens Women’s Safety Framework with Upgraded SHe-Box 2.0 Portal
Context:
The Ministry of Women and Child Development (MWCD) is strengthening workplace safety for women through the revamped Sexual Harassment electronic Box (SHe-Box) Portal, a centralised digital platform for reporting and monitoring workplace sexual harassment complaints.
More on the News
- The revamped SHe-Box Portal was launched on 29 August 2024, while the original SHe-Box online complaint system was first introduced in July 2017.
- It has been developed for the effective implementation of the Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Act, 2013 (POSH Act).
- The portal serves as a single-window platform for filing, tracking and monitoring complaints across public and private sector workplaces.
- It functions as a national repository of Internal Committees (ICs) and Local Committees (LCs) constituted under the POSH Act.
