Six Congress MPs suspended from LS for throwing papers at Speaker

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.

Bengaluru, Feb 27: Defence Minister Rajnath Singh on Thursday said that the situation is moving towards normalcy in Delhi after recent incidents of violence.

"Situation is moving towards normalcy," Rajnath told media here.

Joint Commissioner of Police (Traffic) Narendra Singh Bundela on Thursday said that the law and order and traffic situation in violence-affected parts of Delhi is normal.

"The situation is quite normal and peaceful as far as security and traffic are concerned. We have held talks and conducted patrols with people of all communities. Services such as road cleaning have resumed and traffic flow is normal," Bundela told ANI here.

"People can go out to get their daily needs from the market but we are advising them not to come out in groups," he added.

Meanwhile, the death toll in the incidents of violence in North-East Delhi has risen to 34.

Delhi Police has registered 18 FIRs and 106 people have been arrested in connection with the violence.

Thiruvananthapuram, Feb 7: Kerala Finance Minister T M Thomas Isaac on Friday began presenting the fifth budget of the CPI(M)-led LDF government for the 2020-21 fiscal by making remarks against the Citizenship Amendment Act and the unanimous resolution passed by the state assembly against it.

Stating the amended act was posing a threat to the basic credentials of the Constitution, he said the country was witnessing the biggest protests ever in the post-Independence era.

Students and women are at the forefront of the anti- CAA agitations and the hope of the country lies in the youth who hit the streets vowing they would not let the country down, he said.

Coming down heavily on the BJP-led NDA government at the Centre, Isaac said a communalised government machinery, leaders who talk only about "disgust and hatred" and their party workers who consider violence as their duty was the current reality in the country.

"Generally speaking, it is the present India...The concerns triggered by Citizenship Amendment Act (CAA) and the National Register of Citizens (NRC) are beyond words. The fear of detention centres are hanging above the head of over 19 lakh people of Assam who have lived as Indians till yesterday," he said.

Quoting from a poem 'Fear' by a 15-year old boy from Wayanad Dhruvath Gautham who wrote 'fear is country and silence is an ornament!,' Isaac said "even the imagination of our children is now filled with fear".

Referring to the stringent opposition raised by the Left government in the state against the CAA and NRC, the finance minister lavished praise on the joint protests led by the ruling LDF and opposition UDF against the central act.

Setting aside political differences, the rival fronts in the state had joined hands to protest when the country had faced existential threat which had become a model for other states, he said.

When Chief Minister Pinarayi Vijayan and Leader of the Opposition Ramesh Chennithala jointly protested at the same venue against CAA, Kerala became a model to other states, the senior leader added.

The state showcased the same unity while passing a resolution requesting the centre to repeal the CAA and filing a suit in the apex court against this under the Article 130, he said.

"The country's economy is heading towards a severe economic crisis like that witnessed in 2009," he said.

Earlier, the references to anti-CAA protests had found a place in the Pinarayi Vijayan government's policy address also.

While presenting the policy address in the House, Governor Arif Mohammed Khan had read out references to anti- CAA resolution passed by the house, despite disagreeing with it.

Reading out the the anti-CAA stand of the state government, the Governor said "our citizenship can never be on the basis of religion as this goes against the grain of secularism which is part of the basic structure of our constitution.
