‘Brother not married, so sister has come’: Amit Shah on Congress ‘dynasty’

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 16: Despite the fact that Aam Aadmi Party (AAP) managed to clean sweep in the recently-concluded 2020 Delhi Assembly polls with eight women candidates winning, Chief Minister Arvind Kejriwal's new cabinet does not have a single woman.

This, even as eight AAP women candidates -- Atishi Marlena, Rakhi Birla, Raj Kumari Dhillon, Preeti Tomar, Dhanwati Chandela, Parmila Tokas, Bhavna Gaur and Bandana Kumari emerged victorious in the 2020 Assembly polls.

Also, AAP's poll campaign had put the spotlight on women's issues- free bus rides for women, safety etc.

This year, AAP had fielded nine female candidates out of which only woman candidate Sarita Singh from Rohtas Nagar suffered defeat. In 2015, the party had fielded six women candidates, all of whom won the election.

Atishi Marlena, who won the election from Kalkaji, has served as a key advisor to the AAP leader Manish Sisodia primarily on education policies that transformed public school education in the capital.

Just like Marlena, incumbent MLA Rakhi Birla from Mangolpuri constituency has also failed to comeback to the Cabinet in this term even after bagging over 74,100 votes, with a margin of over 30,000 votes and 58 per cent of the vote share.

She was charged with the Cabinet Ministry of Women and Child, Social Welfare and Languages, for a few months in AAP's first term from 2013 to 2014. During this, period she came to the spotlight as she became the youngest ever cabinet minister of Delhi at the age of 26 and was even called "giant killer" for defeating four-time Congress MLA Raj Kumar Chouhan in 2013 Delhi polls.

Another candidate of AAP, Raj Kumari Dhillon swept Hari Nagar against BJP's Tajinder Pal Singh Bagga by a margin of over 20,100 votes.

Apart from these three, Preeti Tomar (Tri Nagar), Dhanwati Chandela (Rajouri Nagar), Pramila Tokas (RK Puram), Bhavna Gaur (Palam), and Bandana Kumari (Shalimar Bagh)- the other five who won for AAP- do not figure in the new cabinet.

Today at Ramlila Maidan, AAP national convenor Arvind Kejriwal was sworn-in as Chief Minister of Delhi.

Besides him, Manish Sisodia, Satyender Jain, Gopal Rai, Kailash Gehlot, Imran Hussain, and Rajendra Gautamas took oath as the ministers in Delhi.

AAP achieved a landslide victory in the Assembly elections with a clear majority of 62 seats out of 70. 

Dubai/Abu Dhabi, May 7: A group passengers who are scheduled to fly to Kozhikode on the first COVID-19 Indian repatriation flight have begun streaming in to Terminal 2 at Dubai International Airport.

Wearing masks and gloves, the passengers are now waiting for the medical screening and check-in services to begin.

Airport officials gave entry to the departure terminal only to passengers with tickets.

Naif resident Mahamood P.P, 60, was among the first to reach as he was not informed about the change in the flight schedule, he told Gulf News.

“I reached here at 9.30am as I didn’t get any information about the 2.10pm flight getting rescheduled to the evening,” he said.

Suffering from a heart disease, Mahmood, who works as a juice maker at a juice shop near Naif Police station, said he stepped out of his room for the first time in two months.

“As there were many cases in Naif, I never went out because of my health condition. Since I was not in contact with anyone else other than my roommates who also never went out, I didn’t go for the COVID screening also. I was worried that I might be exposed to infection while waiting for the tests,” he said.

He thanked the Indian Consulate for giving him priority to fly home. “I need to go for my heart checkup. So I wanted to fly home as soon as possible.”

However, he said his son, a civil engineer who came here searching for a job, is not flying back though he is on a visit visa.

“Since the UAE government has allowed people on visit visa to stay here till December, he has decided to try his luck in getting a job,” said Mahamood.

Sneha Thomas, who is eight months pregnant, was also among the first to arrive at the airport.

Her husband Somi Jose came to drop her.

Thomas is among 11 pregnant women flying on the Dubai-Kozhikode flight.

Sharjah resident for 30 years, Mohammed Ali Yaseen, who is also the secretary of the Kerala Muslim Cultural Centre in Sharjah, said he is flying home as the restaurant he was running had to be closed due to a demolition plan of the building.

“Three months ago I got the notice to vacate the building and I had to close the restaurant. I was looking for another shop. But then the coronavirus hit. Now there is no point in me opening me a new shop as those who are already operational are not getting any business.”

He said he decided to drop the plan and go home for now. “My visa and license are still valid. I will try to come back when this pandemic ends and things are better.”

Meanwhile, at the Au Dhabi International Airport, families with kids were given priority to proceed towrards check-in. at terminal 3. The passengers coming in right now were mostly women who were on a visit visa. Pregnant women and the elderly too were given priority.
