Kerala floods outcome of cow slaughtering: BJP MLA

New Delhi, Jul 1: 18,653 COVID-19 cases have been reported in India in the last 24 hours, taking the country's tally of coronavirus cases to 5,85,493, informed the Union Health and Family Welfare Ministry on Wednesday.

As per the Ministry, there are presently 2,20,114 active cases in the country. The number of patients cured/discharged and migrated stands at 3,47,979.

507 deaths due to COVID-19 were reported in the last 24 hours taking the total deaths due to the virus to 17,400.

According to the ministry, Maharashtra is the worst-affected state by the virus with 1,74,761 cases including 7,855 fatalities.

Tamil Nadu is the second worst-hit state with 90,167 cases including 1,201 deaths. Meanwhile, Delhi has a total of 87,360 cases.

The Indian Council of Medical Research said that a total number of 86,26,585 tested up to June 30 of which 2,17,931 samples were tested on Tuesday.

Mumbai, Jan 12: Thousands of citizens on Sunday congregated in Mumbai's suburban Jogeshwari to oppose the new citizenship law, the proposed NRC and NPR.

They also condemned last Sunday's violence on the JNU campus in Delhi, where masked men ran riot and attacked students. Leftist organisations had claimed RSS-affiliated ABVP's role in the attack, a charge denied by the students' body.

Former Tata Institute of Social Science (TISS) general secretary Fahad Ahmed told PTI that they assembled under the aegis of 'Hum Bharat Ke Log' in Millat Nagar area.

"Prime minister Narendra Modi should call 56 students from across the country to debate on the CAA, NRC and NPR," Ahmed said in an apparent jibe at Modi's "56 inch chest" remark, which the latter had made ahead of the 2014 Lok Sabha polls.

"Why the PM is not talking to us? Why is he not communicating? Even the Britishers used to talk to Indians whom they ruled, but our PM is not talking to poor people," he alleged.

Bollywood actor Sushasht Singh also spoke on the occasion.

"We are people of this country and such acts (CAA) are tarnishing the image of our country," he said.

At the gathering, people waved banners with slogans like "I Am From Gujarat, My Documents Burned in 2002", "No CAA, Boycott NRC, Stop Dividing India, Don't Divide us", "Save Constitution", written on them.

A large number of police personnel were present at the venue.

The Citizenship Amendment Act (CAA), which was notified on January 10, grants Indian citizenship to non-Muslim minorities migrated to India from Afghanistan, Pakistan and Bangladesh till December 31, 2014, following persecution over their faith.

Massive protests were witnessed against the CAA, mainly by the student community, since its passage by Parliament in December last year.

Opposition parties have been dubbing the CAA an "anti-Muslim" legislation, a charge being debunked by the government.

The Congress and other parties like the TMC have also opposed the proposed National Register of Citizens (NRC) and the National Population Register (NPR).

Union home minister Amit Shah has said that the government won't rest until persecuted refugees are granted Indian citizenship.

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.
