Low pressure over Arabian sea to intensify into ‘cyclonic storm’ soon, says IMD

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

Jan 28: After Union minister Anurag Thakur, on Tuesday, BJP MP Parvesh Verma has stoked a controversy by saying that "Shaheen Bagh protesters will enter houses and rape sisters, daughters." The BJP MP even went on to say that if BJP is voted to power in Delhi, they "will clear Shaheen Bagh protest within an hour."

"If the BJP comes to power in Delhi on February 11, we will clear Shaheen Bagh of all protests and protesters within one hour. Not a single person will be visible," Parvesh Verma said during a meeting at Vikaspuri assembly constituency.

"Lakhs of people gather there [Shaheen Bagh]. People of Delhi will have to think and take a decision. They will enter your houses, rape your sisters and daughters, kill them. There's time today, Modi ji & Amit Shah won't come to save you tomorrow..." the BJP MP told news agency ANI.

"If our government is formed, then give me just a month after February 11, and I will remove all mosques built on government land in my Lok Sabha constituency," the BJP parliamentarian added.

Well, these statements didn't go down well with the netizens, who took to Twitter to express what they felt about the BJP leader's comments. A user wrote, "This is pure, unadulterated hate speech." While other user said, "Only when you thought BJP couldn't stoop any lower."

Earlier, on Monday, BJP leader and Union Minister Anurag Thakur triggered a row after he led the crowd to raise an incendiary slogan that "traitors should be shot". At the rally, Thakur, the Minister of State (MoS) for Finance, shouted: "desh ke gaddaron ko" to which the crowd responded, "goli maro saalo ko" (shoot down the traitors).

Addressing the meeting in support of BJP candidate from Rithala, Manish Chaudhary, Thakur raised the pitch of nationalism as he linked opposition parties with anti-CAA protests in Shaheen Bagh and with alleged anti-India slogans, and then asked the crowd to raise the controversial slogan.

For more than a month, over 200 women have been joined by hundreds of others every day at South East Delhi's Shaheen Bagh at a sit-in protest against the CAA which promises citizenship to only non-Muslim refugees from three neighbouring countries.

Protests have been ongoing in different parts of the country against the amended Citizenship Act (CAA) which grants citizenship to Hindus, Sikhs, Jains, Parsis, Buddhists and Christians fleeing religious persecution from Pakistan, Afghanistan, and Bangladesh if they entered India on or before December 31, 2014.

New Delhi, Jun 9: BJP leader Jyotiraditya Scindia and his mother Madhavi Raje Scindia have tested positive for COVID-19 and are currently undergoing treatment in a Delhi hospital, India Today reported on Tuesday.

They were admitted on Monday to Max Super Specialty Hospital, Saket, after the two complained of throat irritation and fever.

"Not so good news: @JM_Scindia and his mother have tested positive for corona, The former Cong turned BJP leader from MP has been admitted to hospital.. Wish him a speedy recovery!" tweeted Rajdeep Sardesai, consulting editor at the India Today group.

Scindia, former Congress MP from Guna constituency in Madhya Pradesh, quit the party and joined BJP last March. Scindia, who was once Minister of State with independent charge for Power, is the BJP candidate for the upcoming Rajya Sabha elections from Madhya Pradesh.
