The sickening air pollution that led the Indian capital to shut schools and construction sites this week has prompted similar measures in nearby cities.
Officials in the northern state of Uttar Pradesh yesterday said that they expect the acrid smog to blanket the state within days.
For more than a week, New Delhi’s skies have been filled with a thick haze that has made people’s eyes sting and their throats sore.

Air pollution experts blame myriad pollution sources, from diesel-burning cars and seasonal crop burning to garbage fires and stoves fueled with kerosene and cow dung. Winter weather also mean there is less wind to circulate the air.
The smog “remains in the lower atmospheric layer,” said Surya Kant Tripathi, who heads the pulmonary medicine department at King George’s Medical University in Lucknow, the capital of Uttar Pradesh. He urged people to avoid going outdoors unless wearing face masks.
“Higher air pollution levels may take days to settle,” he said.
Lucknow city Director J.P. Gupta said the same smog covering New Delhi was wafting over western parts of Uttar Pradesh and would soon cover the entire state, India’s most populous, with about 210 million people.
In the Uttar Pradesh district of Ghaziabad, considered an eastern suburb of New Delhi, schools were ordered closed along with those in the capital yesterday and today, after which state officials said they would reassess the situation.
There are no official air pollution monitors set up in the Delhi suburban areas, but in both New Delhi and Lucknow, the levels of PM2.5 — the tiny particulate matter that can clog lungs — yesterday were at least above 400 micrograms per cubic meter.
That’s more than 40 times what’s considered safe by the WHO, and more than six times the limit set by Indian law. Some monitoring points were registering levels much higher.
New Delhi has ordered the temporary closure of a nearby coal-burning power plant, as well as construction and demolition sites blamed for sending huge plumes of fine dust particles into the air.
India’s Supreme Court today is to hear a plea demanding that authorities do a better job of monitoring air quality and take more serious steps to cut pollution.
SEEKING CHANGE: A hospital worker said she did not vote in previous elections, but ‘now I can see that maybe my vote can change the system and the country’ Voting closed yesterday across the Solomon Islands in the south Pacific nation’s first general election since the government switched diplomatic allegiance from Taiwan to Beijing and struck a secret security pact that has raised fears of the Chinese navy gaining a foothold in the region. The Solomon Islands’ closer relationship with China and a troubled domestic economy weighed on voters’ minds as they cast their ballots. As many as 420,000 registered voters had their say across 50 national seats. For the first time, the national vote also coincided with elections for eight of the 10 local governments. Esther Maeluma cast her vote in 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. The New York City Police Department (NYPD) said the man was declared dead by staff at an area hospital.

HYPOCRISY? The Chinese Ministry of Foreign Affairs yesterday asked whether Biden was talking about China or the US when he used the word ‘xenophobic’ US President Joe Biden on Wednesday called for a hike in steel tariffs on China, accusing Beijing of cheating as he spoke at a campaign event in Pennsylvania. Biden accused China of xenophobia, too, in a speech to union members in Pittsburgh. “They’re not competing, they’re cheating. They’re cheating and we’ve seen the damage here in America,” Biden said. Chinese steel companies “don’t need to worry about making a profit because the Chinese government is subsidizing them so heavily,” he said. Biden said he had called for the US Trade Representative to triple the tariff rates for Chinese steel and aluminum if Beijing was
