Bombs and weapons recovered in Thalassery

Geneva, Jul 11: The World Health Organization said Friday that it is still possible to bring coronavirus outbreaks under control, even though case numbers have more than doubled in the past six weeks.

WHO chief Tedros Adhanom Ghebreyesus said the examples of Italy, Spain, South Korea and India's biggest slum showed that however bad a outbreak was, the virus could still be reined in through aggressive action.

"In the last six weeks cases have more than doubled," Tedros told a virtual press conference in Geneva.

However, "there are many examples from around the world that have shown that even if the outbreak is very intense, it can still be brought back under control," said Tedros.

"And some of these examples are Italy, Spain and South Korea, and even in Dharavi -- a densely packed area in the megacity of Mumbai -- a strong focus on community engagement and the basics of testing, tracing, isolating and treating all those that are sick is key to breaking the chains of transmission and suppressing the virus."

The novel coronavirus has killed at least 555,000 people worldwide since the outbreak emerged in China last December, according to a tally from official sources compiled by AFP on Friday.

Nearly 12.3 million cases have been registered in 196 countries and territories.

"Across all walks of life, we are all being tested to the limit," Tedros said, "from countries where there is exponential growth, to places that are loosening restrictions and now starting to see cases rise.

"Only aggressive action combined with national unity and global solidarity can turn this pandemic around."

New Delhi, Feb 25: Condemning the violence in Delhi, the Congress on Tuesday demanded that the Prime Minister, the Home Minister and the Chief Minister of Delhi come forward to ensure peace and maintain brotherhood while rising above partisan politics.

"This is Gandhi, Nehru, Patel's India, can any Indian accept this mindless violence? Congress appeals to the people of Delhi to maintain communal harmony and thwart all attempts of the forces dividing the country on the basis of religion," Congress' chief spokesperson Randeep Surjewala told reporters.

Unabated violence and incidents of stone-pelting and murder in the national capital have shattered the nation, he said, while referring to the riots in northeast Delhi over the Citizenship (Amendment) Act that continued for the third day, and demanded stern action against the culprits.

"Our appeal to the prime minister, the home minister and the Delhi chief minister is, can you rise to the occasion, leave aside your political partisanship and views, and become really not leaders of your parties but leaders of the society so that harmony, peace, and non-violence prevail," he said.

The Congress party will stand with the Centre and the Delhi government in every way to maintain brotherhood and harmony in the society, he said.

"Do not fail this country because you belong to different political parties," Surjewala said, adding this was a sincere appeal "on behalf of people of Delhi and the country" to Prime Minister Narendra Modi, Home Minister Amit Shah and Chief Minister Arvind Kejriwal.

"There is no place for violence in Gandhi ji's India... Today there is a need to establish peace on the ground and maintain brotherhood," he said.

Surjewala said the party also prays for the speedy recovery of DCP Amit Sharma and the hundreds of other people who have been injured in the violence.

"We also condemn the firing at three journalists Arvind Gunasekar, Saurabh Shukla and Akash and pray for their good health," he said.

"We strongly condemn these brutal riots and demand that the culprits are identified and stern action is taken against the real culprits and miscreants. The Congress mourns the death of Head Constable Ratan Lal and others in the violence," Surjewala said.

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.
