Theni, Mar 29: A young man under home quarantine for coronavirus after return from Sri Lanka suddenly ran out of his house and fatally bit a 80-year old woman in his neighbourhood in a village near here, police said on Saturday.

The woman with injuries in her neck was hospitalised late Friday after the incident but died on Saturday without responding to treatment, they said.

The man, a resident of Jakkamanayakanpatti and engaged in seasonal business in clothing, was overpowered and handed over to police, who arrested him and investigations were on.

He had recently returned from Sri Lanka and directed to remain under quarantine by health authorities as per the protocol for foreign returnees to check coronavirus spread.

He came out of his house on Friday evening and all of a sudden, denuded himself and began running through the street.

Shocked family members including his father gave a chase even as he caught hold of Nachiyammal, seated on her house’s front yard and bit hard her neck.

The man’s kin overpowered him and admitted the woman to nearby Bodi Government Hospital where doctors on Saturday said she succumbed to her injuries, not responding to treatment. Health authorities were unavailable for comments immediately.

United Nations, Jul 10: India is a "good example" as solar auctions have seen popularity amidst the height of the COVID-19 pandemic, UN chief Antonio Guterres said on Thursday, underlining that renewable energy is the only energy source expected to grow in 2020 and offers more jobs than the fossil fuel industry.

In his remarks to the International Energy Agency "Clean Energy Transition Summit'', UN Secretary-General Guterres urged the international community to commit to further usage of coal and to end all external financing of coal in the developing world.

"Coal has no place in COVID-19 recovery plans. Nations must commit to net-zero emissions by 2050 and submit more ambitious national climate plans before COP-26 next year," he said.

"The seeds of change are there. Renewable energy is the only energy source expected to grow in 2020. Solar auctions have seen popularity amidst the height of the pandemic. India serves as a good example. Renewables offer three times more jobs than the fossil fuel industry," Mr Guterres said.

Last month, Adani Green Energy said it has bagged the first of its kind manufacturing-linked solar contract worth Rs 45,000 crore from the Solar Energy Corporation of India (SECI) to develop 8 GW electricity generation capacity and 2 GW equipment manufacturing facility in the country.

Mr Guterres said he has asked all countries to consider six climate positive actions as they rescue, rebuild and reset their economies.

"We need to make our societies more resilient. We need green jobs and sustainable growth," he said, adding that bailout support to sectors such as industry, aviation and shipping should be conditioned on alignment with the goals of the Paris Agreement.

Countries also need to stop wasting money on fossil fuel subsidies and place a price on carbon, he said, noting that countries need to consider climate risk in their decision making.

"Every financial decision must take account of environmental and social impacts. Overall, we need to work together," he 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.
