Karunanidhi denies threatening to pull out of UPA government

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.

Panaji, Jan 28: Bureaucrat-turned-activist Kannan Gopinathan on Tuesday said even some "RSS people" are convinced the Citizenship Amendment Act is a bad law but are keeping quiet as the NDA government at the Centre is their own baby.

Speaking in Panaji, he further said the Narendra Modi government was behaving like a "drunken teenager" which needs to be questioned or else it will end up destroying homes.

"I was detained twice in UP, kept the whole day, because they (government) do not want the questioning (of CAA). I have met so many RSS people, they also understand this...if you have this conversation, they also understand the government has done something (wrong) and they have been asked to support it," he claimed.

He said the line of thought among these RSS people (he met) was "just support it (CAA)" as they don't want an altercation because the "government is their baby".

"He (government) is not a normal baby, he is a drunken teenager. He should be asked questions because when he starts destroying, he does not destroy somebody else's home but your own home," Gopinathan said.

He also hit out at those who have been claiming that the people protesting against the CAA are unaware about the law and have not even read it.

Gopinathan claimed if one had asked supportive MPs about the CAA on the day it was passed in Parliament, several of them would not have been able to speak on it as "they would not have known what was passed, because they were not given time (to go through the bill)".

He said, earlier, such legislation was passed after several rounds of consultation but "now, by night, it becomes an Act", adding (now) "everything is a surgical strike".

Gopinathan, in a possible reference to the National Register of Citizens exercise carried out in Assam, also claimed "thousands of people are in detention centres".

"It is your fundamental right to peacefully assemble without arms, Article 19 (1) (D) (of the Constitution)," he said at a function organised by a group opposed to CAA.

Gopinathan said people "always felt they were in a democracy" because they never tried to fly, when in reality "you are in a cage".

"The moment you want to fly you realise you are in a cage," he said, adding that "we have to question, we have to ask ourselves where are we going".

"When you don't allow a person to speak against an incorrect legislation, then what is democracy? What is freedom of expression?" Gopinathan questioned.

Gopinathan, a 2012 batch AGMUT cadre Indian Administrative Service officer, was the secretary, Power Department of the Union Territories of Daman and Diu, and Dadra and Nagar Haveli when he resigned on August 21 last year.

At the time, he had claimed the people of Jammu and Kashmir were being denied freedom of expression following abrogation of Article 370 by the Centre.

New Delhi, Jan 31: The Supreme Court Friday dismissed the plea filed by one of the four death row convicts in the Nirbhaya gang-rape and murder case, Pawan Gupta, seeking review of its order rejecting his juvenility claim.

The review plea filed earlier in the day was taken up for consideration in-chamber by a bench comprising Justices R Banumathi, Ashok Bhushan and A S Bopanna. 

On January 20, the apex court had rejected the plea by Pawan who had challenged the Delhi High Court's order dismissing his juvenility claim.

Advocate A P Singh, who is representing Pawan in the case, said he filed a petition on his behalf seeking review of the top court's January 20 order on Friday.

While dismissing the plea, the top court had said there was no ground to interfere with the high court order that rejected Pawan's plea and his claim was rightly rejected by the trial court as also the high court.

It had said the matter was raised earlier in the review petition before the apex court which rejected plea of juvenility taken by Pawan and another co-accused Vinay Kumar Sharma and that order has attained finality.

Singh had argued that as per his school leaving certificate, he was a minor at the time of the offence and none of the courts, including trial court and high court, ever considered his documents.

Solicitor General Tushar Mehta, appearing for the Delhi Police, had said Pawan's claim of juvenility was considered at each and every judicial forum and it will be a travesty of justice if the convict is allowed to raise the claim of juvenility repeatedly and at this point of time.

The trial court on January 17 issued black warrants for the second time for the execution of all the four convicts in the case -- Mukesh Kumar Singh (32), Pawan (25), Vinay (26) and Akshay (31) -- in Tihar jail at 6 am on February 1. Earlier, on January 7, the court had fixed January 22 as the hanging date.

As of now, only Mukesh has exhausted all his legal remedies including the clemency plea which was dismissed by President Ram Nath Kovind on January 17 and the appeal against the rejection was thrown out by the Supreme Court on January 29.

Convict Akshay's curative petition was dismissed by the top court on January 30. Another death row convict Vinay moved mercy plea before President on January 29, which is pending.

Singh has also approached the trial court seeking stay on the execution scheduled on February 1, saying the legal remedies of some of the convicts are yet to be availed.

A 23-year-old paramedic student, referred to as Nirbhaya, was gang-raped and brutally assaulted on the intervening night of December 16-17, 2012, in a moving bus in south Delhi by six people before she was thrown out on the road.
