Jailed in Pak on charge of spying, Indian techie Hamid Ansari finally returns home

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.

New delhi, Feb 10: The Supreme Court on Monday upheld the constitutional validity of the SC/ST Amendment Act, 2018, and said a court can grant anticipatory bail only in cases where a prima facie case is not made out.

A bench headed by Justice Arun Mishra said a preliminary inquiry is not essential before lodging an FIR under the act and the approval of senior police officials is not needed.

Justice Ravindra Bhat, the other member of the bench, said in a concurring verdict that every citizen needs to treat fellow citizens equally and foster the concept of fraternity.

Justice Bhat said a court can quash the FIR if a prima facie case is not made out under the SC/ST Act and the liberal use of anticipatory bail will defeat the intention of Parliament.

The top court's verdict came on a batch of PILs challenging the validity of the SC/ST Amendment Act of 2018, which was brought to nullify the effect of the apex court's 2018 ruling, which had diluted the provisions of the stringent Act.

Kolkata, Jan 12: Strongly defending the new citizenship law, Prime Minister Narendra Modi said on Sunday the dispute that has arisen over it has made the world aware of persecution of religious minorities in Pakistan.

He, however, deplored that a section of the youth is being “misguided” over the Citizenship (Amendment) Act, which is aimed at giving and not taking away anybody's citizenship rights.

“CAA is not about taking away citizenship, it is about giving citizenship. Today, on National Youth Day, I would like to tell this to the youngsters of India, West Bengal, North East that this is not an overnight law for giving citizenship.

“We must all know that any person of any religion from any country of the world who believes in India and its Constitution can apply for Indian citizenship through due process. There's no problem in that,” he told a gathering at Belur Math, the headquarters of Ramkrishna Mission.

Modi said even Mahatma Gandhi had favoured Indian citizenship to those fleeing religious persecution and that his government has only delivered on the wishes of the freedom fighters.

Referring to anti-CAA protests in the North-East, Modi vowed to protect the distinct identity and culture of the people of the region, and asserted the new law will not hurt their interests.

“We've only done what Mahatma Gandhi had said decades ago. Should we send these refugees back to die? Are they our responsibility or not? Should we make them our citizens or not?” he said, evoking a thunderous applause by the gathering.

Modi said some people with political interests are deliberately spreading rumours about the new citizenship law, despite “complete clarity” over the CAA.

“Our initiative to amend the citizenship act has created a dispute. It is the result of our initiative that Pakistan will now have to answer why they have been persecuting minorities for the last 70 years. Human rights have been demolished in Pakistan,” he said.

Seeking to assuage the concerns of the people of the North-East, Modi called the region “our pride”. “Their culture, traditions and demography remains untouched by this amended law,” he said.

He said the citizenship law was only “changed a little” for those who were ill-treated in Pakisan after Partition.

“They were having a bitter time living there. Women were in danger of losing their pride,” he said.

“Young people have understood the whole thing but those who want to indulge in politics over it will not,” he said.

Modi said five years ago, there was disappointment among the youth of the country, but the situation has changed now.

“Not just India, the entire world has a lot of expectations from the youth of the country. The youth are not afraid of challenges....they challenge the challenges,” he said at the Belur Math, the abode of Swami Vivekananda for several years until his death in 1902, aged 39 years.

Modi, an ardent devotee of Vivekananda, spent the night at the Math.

He has a long association with the Ramkrishna Mission order founded by Vivekananda in 1897. Inspired by the teachings of Vivekananda, Modi had arrived at the Mission Ashram in Gujarat's Rajkot and expressed desire to join the order.

Swami Atmasthananda, who later went on to become the 15th president of the Ramakrishna Math and the Ramakrishna Mission, then headed the Rajkot branch and had advised him that sanyas was not for him and that he should work among people.

During those days, Modi used to regularly meet Atmasthananda and sought his spiritual guidance.

Although Modi went back after spending some time there his the relationship with Swami Atmasthananda and the Ramkrishna Mission continued.

Whenever Modi used to visit Kolkata, even during his days as Gujarat chief minister, he would travel to the Math.

In 2013, during his Kolkata visit, he had gone to Belur and sought the blessings from Atmasthananda.

He had in 2015 called on ailing Swami Atmasthananda at Ramakrishna Mission Seva Pratisthan, a hospital run by the Mission in south Kolkata and enquired about his health.

After Atmasthananda's death in 2017, Prime Minister Modi had termed it as a “personal loss”.

On Sunday, the prime minister paid tributes to Swami Vivekananda on his birth anniversary, which is celebrated as the National Youth Day, and spent some time in the spiritual leader's room in quietude.
