For the first time ever, more than 1,800 public elementary schools in India’s capital were closed yesterday to protect children from exposure to dangerous levels of air pollution.
The decision affected more than 1 million children.
A thick, acrid smog has settled over the capital over the past week, a combination of smoke from burning crops in surrounding agricultural states, fireworks on the Hindu festival of Diwali, dust and vehicle emissions.

Levels of the most dangerous particles PM2.5 — fine particulate matter measuring 2.5 micrometers or smaller in diameter — reached 600 micrograms per cubic meter in different parts of the city last week, the Delhi Pollution Control Committee said.
Sustained exposure to that concentration of PM2.5 is equivalent to smoking 40 cigarettes a day, said Sarath Guttikunda, director of Urban Emissions, an independent research group.
The particles are small enough to deeply penetrate the lungs and enter the bloodstream, increasing the risk of stroke and heart failure, and can cause severe respiratory problems including asthma and pneumonia.
Conditions in the metropolis, home to about 20 million people, were particularly bad last week because there was little wind and the cloud of pollutants was “just going round and round,” Guttikunda said.
Teachers and parents said the effects on children were visible.
Meenakshi Sahni, principal of the Modern School, closed her private school because of air pollution for the first time on Friday and advised parents via text message to keep their children indoors. There was “widespread coughing” among students and faculty members last week, she said.
“You could actually feel that there was something weighing down on them physically,” Sahni said. “Even at the gathering in the auditorium, you could feel as if somebody is strangling you.”
Foreigners and Indian elites have expressed growing alarm about winter air pollution in recent years, and some embassies have begun discouraging families with children from moving there.
However, this year is the first time Indian schools have taken such precautions. As they waited to pick up children after school on Friday, parents described an array of their children’s symptoms, including burning eyes, incessant coughing and congestion that does not clear.
Seema Sansanwal, 38, said when she takes her three-year-old son to the doctor, the doctor “tells us, ‘Go out for an excursion and leave the city for some days, and he will be fine,’ instead of diagnosing.”
Poonam Tokas, 35, said she could not believe her eyes at the smog on Monday, the day after Diwali, and has forbidden her children from playing outside until it clears.
“We are going to buy masks this evening,” she said. “But I do not think anyone can save us from the wrath of nature.”
Indu, a municipal councilor from South Delhi and a member of the municipal corporation’s education committee, said it was the first time the city had taken such measures.
“We took stock of how bad the smog and pollution level had reached,” said Indu, who uses only one name. “Even doctors are advising against going for walks. Television channels are presenting reports showing that pollution is as bad as smoking two dozen cigarettes.”
She said that they are “hoping weather conditions will improve on Monday [tomorrow],” allowing the schools to reopen.
“At least children would have stayed away from the polluted outdoors over the weekend,” she said.
Keeping children at home reduces their level of activity and lessens their exposure to air pollution, especially in areas where vehicle emissions are at their highest, Guttikunda said.
However, he added that the air quality inside a house often was not much better than outside, unless doors and windows were closed and sealed.
“If you open them for even half a minute, it is gone,” he said.
‘IN A DIFFERENT PLACE’: The envoy first visited Shanghai, where he attended a Chinese basketball playoff match, and is to meet top officials in Beijing tomorrow US Secretary of State Antony Blinken yesterday arrived in China on his second visit in a year as the US ramps up pressure on its rival over its support for Russia while also seeking to manage tensions with Beijing. The US diplomat tomorrow is to meet China’s top brass in Beijing, where he is also expected to plead for restraint as Taiwan inaugurates president-elect William Lai (賴清德), and to raise US concerns on Chinese trade practices. However, Blinken is also seeking to stabilize ties, with tensions between the world’s two largest economies easing since his previous visit in June last year. At the
Nearly half of China’s major cities are suffering “moderate to severe” levels of subsidence, putting millions of people at risk of flooding, especially as sea levels rise, according to a study of nationwide satellite data released yesterday. The authors of the paper, published by the journal Science, found that 45 percent of China’s urban land was sinking faster than 3mm per year, with 16 percent at more than 10mm per year, driven not only by declining water tables, but also the sheer weight of the built environment. With China’s urban population already in excess of 900 million people, “even a small portion
UNSETTLING IMAGES: The scene took place in front of TV crews covering the Trump trial, with a CNN anchor calling it an ‘emotional and unbelievably disturbing moment’ A man who doused himself in an accelerant and set himself on fire outside the courthouse where former US president Donald Trump is on trial has died, police said yesterday.

Beijing is continuing to commit genocide and crimes against humanity against Uyghurs and other Muslim minorities in its western Xinjiang province, U.S. Secretary of State Antony Blinken said in a report published on Monday, ahead of his planned visit to China this week. The State Department’s annual human rights report, which documents abuses recorded all over the world during the previous calendar year, repeated language from previous years on the treatment of Muslims in Xinjiang, but the publication raises the issue ahead of delicate talks, including on the war in Ukraine and global trade, between the top U.S. diplomat and Chinese
