A survey of over 44,000 households across Delhi, Gurugram, Noida, Faridabad and Ghaziabad found that 75% of families report at least one member suffering from ailments such as sore throat or cough (42%) and burning eyes, headache or disturbed sleep (25%) owing to worsening air pollution. Despite a 77.5% decline in stubble-burning incidents in nearby states, pollution levels remain severe, with PM2.5 hitting 488 µg/m³ — over three times the pre-festival level. About 44% of households are curtailing outdoor exposure and boosting immunity via diet & indoor air purifiers. (PC: X)

The International Union for Conservation of Nature (IUCN) has downgraded the green turtle’s status from Endangered to Least Concern, marking a major conservation success. However, experts warn that the species remains far below historic population levels, facing ongoing threats from habitat loss, fishing, and climate change. In regions like Raine Island, Australia, declining hatch rates highlight the continued urgency of protection efforts. In contrast, Arctic seals face worsening conditions: the hooded seal is now Endangered, and bearded and harp seals are Near Threatened due to melting sea ice that jeopardizes their breeding, feeding, and survival.

Delhi Chief Minister Rekha Gupta said the city has successfully tested artificial rain at Burari. The project, developed by IIT Kanpur and the Delhi government, aims to reduce air pollution through cloud seeding. Experts fired special flares to form rain clouds, marking a major step in pollution control. If weather conditions remain good, Delhi could see its first artificial rainfall on October 29. The Environment Minister said the trial flight tested the system’s safety and coordination. The project has approvals from 23 departments and will continue till November with help from IITM Pune and IMD. (PC: HT)

On 22 October 2025, the national capital’s air-quality readings showed a stark contrast: CPCB reported an AQI of approximately 351, while IQAir’s measurement soared past 1,100. The explanation lies in differing methodology — CPCB’s index is capped at 500, uses reference-grade monitors and Indian standards, while IQAir draws on lower-cost sensors, global standard conversions and reports raw values beyond 500. Both readings are technically correct within their frameworks, but the discrepancy has sparked public confusion and highlights the challenge of interpreting air-quality data. (PC: NDTV)

Delhi's air quality plummeted to the 'very poor' category following Diwali celebrations, with some areas recording 'severe' levels. The overall Air Quality Index (AQI) stood at 338 as of 8 AM on Wednesday, October 22, 2025. Notably, Punjabi Bagh and Wazirpur had AQIs of 433 and 401, respectively, both in the 'severe' category. The spike in pollution is attributed to widespread firecracker use beyond the stipulated time, leading to a toxic mix of pollutants and heavy metals. Experts warn of worsening conditions due to factors like stubble burning and unfavorable meteorological conditions. (PC: PTI)
