The Delhi Pollution Control Committee reported extreme surges in PM2.5 and PM10 concentrations across the capital early Monday morning, with some monitoring locations recording particulate matter dozens of times above safe standards. However, official tracking faced severe disruptions as the number of non-reporting stations escalated from one to 36 during the hours of heaviest firecracker use. Analysts caution that missing information from Central Pollution Control Board stations artificially halved peak measurements, potentially masking the true severity of the situation. Medical experts emphasize that fine particles from this pollution enter the bloodstream and elevate risks for strokes,…

New Delhi: Most of the missing air quality data from Delhi Pollution Control Committee (DPCC) monitoring stations on Diwali night was updated, revealing alarmingly high concentrations of particulate matter during the early hours of Monday, with readings at some locations soaring several times above the prescribed limits.
However, gaps in the official pollution data persisted, with some particulate matter readings still unavailable and data from Central Pollution Control Board (CPCB) monitoring stations remaining missing, raising concerns over the completeness and reliability of the air quality records, experts said.
At RK Puram, for instance, PM2.5 levels surged to 2,389 micrograms per cubic metre at midnight, nearly 40 times the prescribed limit of 60 micrograms per cubic metre.
PM2.5, fine particulate matter that can penetrate deep into the lungs and enter the bloodstream, is a major pollutant of concern because of its harmful effects on human health.
PM10 concentration at the station touched 2,881 micrograms per cubic metre at the same time, against the permissible limit of 100 micrograms per cubic metre.
At Anand Vihar, PM10 concentration peaked at 3,490 micrograms per…
Urban planners have designated the Woodlands parcel for residential development without conservation set-asides, concluding the fragmented habitat cannot support long-term ecological viability once enclosed by major infrastructure. However, an environmental assessment warns the project will severely disrupt movement corridors for threatened species like the Sunda pangolin and straw-headed bulbul. Planners have proposed perimeter green spaces and specialized landscaping to maintain regional wildlife connectivity.
Speaking at the Cop31 summit in Turkey, international climate observers are monitoring Beijing's expanding global influence as its domestic carbon emissions steadily decline. China's overwhelming manufacturing dominance in renewables now serves as a primary economic engine to counterbalance weak domestic spending. Falling behind this accelerating structural transition threatens both Western economic competitiveness and broader efforts to stabilize the global climate.
Data presented at the Cop31 climate talks in Antalya shows that elevated oil and gas prices triggered by Middle East conflict are accelerating global clean energy adoption. While lower coal and oil consumption in the US and China is easing fossil fuel pollution, expanding land-use degradation and deforestation are offsetting these gains. Climate analysts caution that the world is rapidly exhausting its remaining carbon budget to stay within safe temperature thresholds.
