HC reserves order on plea of 20 disqualified AAP MLAs

New Delhi, Jun 5: India registered its highest spike in COVID-19 cases with 9,851 more cases and 273 deaths reported in the last 24 hours. The total number of cases in India reached 2,26,770 including 1,10,960 active cases, said the Union Ministry of Health and Family Welfare.

The Ministry informed that 1,09,462 persons have been cured/discharged/migrated while 6,348 people have succumbed to the disease so far.

Maharashtra has so far reported 77,793 cases, more than any other state in the country, while the total number of active cases in the state stands at 41,402.

In Tamil Nadu, 27,256 cases have been detected so far while Delhi has reported 25,004 coronavirus cases.

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, Jun 4: Press Council of India (PCI) member BR Gupta has resigned from his post, saying he was unable to work individually or collectively for the media, which is in a "deep crisis".

"I have tendered my resignation as a Press Council of India member," Gupta told PTI.

He said the PCI had the responsibility to encourage media and media professionals constantly.

"But everyone now realises that the media scenario is in a deep crisis. The motto for which the Council was created was not being fulfilled and I felt I was not doing anything remarkable for the freedom of media," Gupta said.

He claimed that the PCI was not a wholly representative body for the media.

"Then how can we come out of the crisis being faced by the media and mediapersons? It is a big challenge for us. I have quit as I have not been able to work individually or collectively being a PCI member," Gupta added.

Referring to salary cuts and job losses, he said media and mediapersons were struggling for social, political and economic justice.

When contacted, PCI chairman Justice C K Prasad said Gupta's resignation has not been accepted yet.

"I have received it (the resignation). I have not gone through it. It has not been accepted," Prasad told PTI.

Gupta was appointed as a PCI member for a three-year term on May 30, 2018.

He said liberty is one of the basic features of the preamble to the Constitution that continues to inspire people and the media.

"It is difficult (for me) to fulfil the unbiased role and responsibility to help citizens and the media for making democracy stronger," Gupta said.
