Gulf storm played bigger role in Delhi air pollution

New Delhi, Nov 17:  A West Asian dust storm has been identified as the chief trigger behind the recent air pollution crisis in Delhi.

While stubble burning was said to be a key cause for the toxic smog in the national capital, prompting a spat between Delhi government and governments of neighbouring states, a Centre-run monitoring agency said the particulates from the dust storm that entered the upper atmospheric layer of Delhi and the larger region also contributed to a spike in air pollution levels.

On November 8, the contribution of the dust storm was 40 per cent, eclipsing the role of emissions from stubble burning, which stood at 25 per cent, the Pune-based System of Air Quality And Weather Forecasting And Research (SAFAR) said.

That was the day pollution levels peaked with PM2.5 concentration reaching 640 micrograms per cubic metre, according to the SAFAR scientific assessment report of the week-long pollution crisis accessed by news agency.

"Rest was made up of emissions from local sources such vehicular combustion. If external sources did not have any role, levels of PM2.5 during this period could have been around 200 micrograms per cubic metre," the report has stated.

Uptick in air pollution levels prompted Aam Admi Party led Delhi government to impose a swries of emergency measures in the national capital such as a ban on the entry of trucks and construction activities yielded positive results, the agency said, putting the gains at around 15 per cent in terms of percentage.

PM2.5 are ultrafine particulates, up to 30 times finer than a width of a human hair, which can lodge deep in the lungs and enter the bloodstream, causing irreparable harm to living beings.

The 24-hour prescribed standard of this variety of suspended particulate matter is 60 micrograms per cubic metre.

SAFAR, an arm of the Indian Institute of Tropical Meteorology, said particulates from the dust storm, which swept across Iraq, Kuwait, and Saudi Arabia between the last week of October and November 4, entered the upper atmospheric layer of Delhi and the larger region.

Moreover, according to the report, stubble burning in Punjab, Uttar Pradesh and Haryana were very high on November 6 and as upper air winds became North Westerly (towards Delhi), pollutants were strongly pumped in, exacerbating the situation.

"As per SAFAR forecasting model, the pollution contribution of Gulf Dust Storm on peak day (8th Nov 2017) was around 40 per cent and 25 per cent from stubble burning," the report said.

Till about November 6, the mean PM2.5 level remained between 140-190 ug/m3, usual for this time of the year, SAFAR, the only agency which puts out pollution forecast bulletins in India, said.

Subsequently, from around November 10, there was no pumping of dust from West Asia. Influence of stubble burning also came down as upper air winds slowed down and changed direction, resulting in a brief respite from pollution.

"However, localized weather took over by the evening of November 11. Before pollutants could be flushed, inversion layer (beyond which pollutants cannot escape) fell down from 1600 metres to just 45 metres in eight hours and Delhi entered the severe zone again which delayed full recovery by two days," SAFAR said.

An Israeli airstrike on the office of Syria’s Baath party in Lebanon’s capital Beirut has killed the Lebanese resistance movement Hezbollah's Media Relations Officer, Mohammad Afif, reports say.

Lebanon's National News Agency (NNA) reported that the Israeli raid struck the Ba'ath party’s building in central Beirut district of Ras Al-Naba'a on Sunday, adding that the strike was an attempt to assassinate the leader of the resistance media front.

According to Baath Secretary-General Ali Hijazi, Afif was having a meeting in the Baath Party headquarters when Israel carried out the attack.

"Afif did not fight with weapons and did not lead a military unit in Hezbollah. Rather, he led a media unit," he said.

Reuters, Sky News, Al Jazeera and a number of Henrew-language media reported that Afif was killed in the Israeli strike.

However, Hezbollah has not yet confirmed Afif’s death or whether he was present at the site or not.

Earlier, the Lebanese Health Ministry said at least one person was killed and three others injured after an Israeli strike targeted a central district in Beirut.

Lebanon's al-Mayadeen television network reported that five people were killed in the attack.

The latest development came after Afif said Hezbollah was behind the Caesarea operation and targeting Netanyahu’s home during a speech at the Ghobeiry area in the southern suburbs of Beirut on October 22.

This was the second assassination attempt on Afif in the last two months, after he survived an attack on the Hezbollah media relations office several weeks ago.

Israel launched a ground assault and massive air campaign against Lebanon in late September after a year of exchanging fire across the Lebanese border in parallel with the Gaza war.

At least 3,287 people have been killed in Israeli strikes in Lebanon over the past year, with the vast majority in the past seven weeks. Another 14,222 have been wounded, mostly women and children.

In response to the ongoing aggression, the Lebanese resistance movement Hezbollah has been staging hundreds of retaliatory strikes against the occupied Palestinian territories and the Israeli forces trying to advance on southern Lebanese areas.

The movement has vowed to sustain its strikes until the regime ends the escalation.

Bengaluru, Nov 22: For the second day running, the Karnataka BJP on Friday staged a statewide protest condemning the government’s alleged move to notify land of farmers as Waqf property.

The BJP staged a protest before the offices of Deputy Commissioners at district headquarters.

The BJP leaders are vehemently demanding that the state government cancel a 1974 Gazette notification in this regard.

The agitators are also demanding scrapping of the Waqf Board and the resignation of Chief Minister Siddaramaiah and Minister for Waqf and Housing Zameer Ahmad Khan.

The BJP MLAs, MLCs, MPs gathered in the premises of Freedom Park and staged a protest under the leadership of Leader of Opposition R. Ashoka and slammed the state government.

MLA T.S. Srivatsa led the protest in Mysuru and hundreds of party workers and farmers staged the protest under the leadership of former MP Pratap Simha in Kodagu.

Former MP Sumalatha Ambareesh led the agitation in Mandya.

This was the first time that Sumalatha took part in the party’s programme after the Lok Sabha elections.

State President B.Y. Vijayendra claimed, “The Congress government in Karnataka is issuing notices to farmers claiming the ownership of their lands to the Waqf Board and pushing them on the streets overnight.”

In the first week of December, three teams formed by the BJP will travel across the state and record the grievances of farmers.

“The state government is attempting to snatch away the lands belonging to temples as well,” Vijayendra alleged and added that the teams would comprise all senior leaders of the BJP.

Meanwhile, the police have taken Sri Ram Sena chief Pramod Muthalik into custody while staging a protest march to the office of Zameer Ahmad Khan in Bengaluru.

Muthalik along with Hindutva activists was planning to lay siege to Zameer’s office over the Waqf row.

The police stopped Muthalik and requested him to submit the memorandum by reaching the minister’s office in a vehicle. However, Muthalik refused to go with the police and continued his footmarch. The police took him into custody following arguments.

Advisors to US President-elect Donald Trump have instructed his allies and associates to refrain from using the inflammatory language they previously employed when discussing issues related to migrants and the deportation of asylum seekers, in a bid to avoid “looking like Nazis.”

US media reports said that Trump’s associates had been asked to stop using the word “camps” to describe potential facilities that would be used to accommodate migrants rounded up in deportation operations across the country.

The reports said the US president-elect’s allies had been ordered to stave off such charged terms as they would bring to mind “Nazis,” and be used against Trump.

“I have received some guidance to avoid terms, like ‘camps,’ that can be twisted and used against the president, yes,” one Trump ally told American monthly magazine Rolling Stone.

“Apparently, some people think it makes us look like Nazis.”

The presidential advisers also cautioned surrogates and allies to keep racist terms, which have dogged Trump’s campaign, out of their remarks.

They said with Trump’s heated rhetoric that used to compare undocumented immigrants to “animals” and his slight that they are “poisoning the blood of our country,” detractors did not need to reach too far to find parallels to Nazi Germany.

Stephen Miller, who Trump tapped to be his deputy chief of staff of policy, specifically used the word “camps” to describe holding facilities that he hoped the military could put together for immigrants.

Tom Homan, who served as the acting director of Immigration and Customs Enforcement and is chosen by Trump to be in charge of the US borders, was no stranger to such language.

“It’s not gonna be a mass sweep of neighborhoods,” he said in an interview earlier this week. “It’s not gonna be building concentration camps. I’ve read it all. It’s ridiculous.”

Becoming a little more forthright about the new government’s aggressive deportation plans, Homan likened the early days of the Trump administration to the initial invasion of Iraq in 2003.

“I got three words for them – shock and awe,” he said. “You’re going to see us take this country back.”

Trump made immigration a central element of his 2024 presidential campaign but unlike his first run, which was mainly focused on building a border wall, he has shifted his attention to interior enforcement and the removal of undocumented immigrants already in the United States.

People close to the US president and his aides are laying the groundwork for expanding detention facilities to fulfill his mass deportation campaign promise.

The businessman-turned-politician deported more than 1.5 million people during his first term.

The figure do not include the millions of people turned away at the border under a Covid-era policy enacted by Trump and used during most of Biden’s term.
