Despite the ominous signs building up in the days leading to Diwali – drop in temperature, change in wind direction and stubble burning in states to the north, pollution monitors did not put in place arrangements in accordance with emergency conditions.

Despite a ban on firecrackers put in place by the Supreme Court in 2019, people in the national capital burst them with gay abandon. Here, two children light crackers in Vaishali in Ghaziabad district, Uttar Pradesh. Photo: Vikas Choudhary / CSE
Air quality will be severe November 5 and 6, according to forecasts. It will start to improve November 7, according to the Indian Institute of Tropical Meteorology, Pune. Here, a tanker sprinkles water on a road in Anand Vihar, Delhi to reduce dust. Photo: Vikas Choudhary / CSE
