New Delhi, Jun 15: Average temperature of India experienced a rise of 0.7 degree Celsius, along with decline in rainfall, significant increase in frequency of very severe cyclonic storms and droughts in over a decade due to human activities, the Ministry of Earth Sciences in its research report said.

The contentions were made in a report issued by the ministry on the impact of climate change. It will be published by Union Minister Harsh Vardhan on June 19.

According to the report, "Since the middle of the twentieth century, India witnessed rise in temperature; decrease in monsoon; rise in extreme temperature and rainfall, droughts, and sea levels; and increase intensity of severe cyclones.

The report, prepared by researchers of the Centre for Climate Change Research, a cell under The Ministry's Indian Institute of Tropical Meteorology, Pune, further stated that there is compelling scientific evidence that human activities have influenced these changes in regional climate.

India's average temperature has risen by around 0.7 degrees Celsius during 1901-2018, it said, adding that the rise is largely on account of GHG-induced warming and partially offset by forcing due to anthropogenic aerosols.

It states that the average temperature over India is projected to rise by 4.4 degrees Celsius, while the intensity of heat waves is likely to increase by 3-4 times by the end of the century.

In the 30-year period between 1986 and 2015, temperatures of the warmest day and the coldest night of the year have risen by about 0.63 degrees Celsius and 0.4 degree Celsius.

According to the report, by the end of the century, the temperatures of the warmest day and the coldest night are projected to rise by approximately 4.7 degrees Celsius and 5.5 degrees Celsius, respectively.

Alarmingly, sea surface temperature of the tropical Indian Ocean has also risen by one degrees Celsius on average during 1951-2015.

"The frequency of very severe cyclonic storms during the post-monsoon season has increased significantly (+1 event per decade) during the last two decades (2000-2018)," it added.

This came in the backdrop of Cyclone 'Amphan' and 'Nisarga' which made landfalls on May 20 and June 3 and killed several people, flattened villages, and destroyed farms.

"This is the first-ever climate change assessment report for India. This report will be very useful for policy makers, researchers, social scientists, economists, and students," said M. Rajeevan, secretary, the Ministry of Earth Sciences.

Besides this, the report also highlighted various other unnerving data on climate change in the country. Both the frequency and extent of droughts have increased significantly during 1951-2016.

The overall decrease of seasonal "summer monsoon rainfall" during the last 6-7 decades has led to an increased propensity for droughts over India.

"In particular, areas over central India, southwest coast, southern peninsula and north-eastern India have experienced more than 2 droughts per decade, on average, during this period. The area affected by drought has also increased by 1.3 per cent per decade over the same period."

The Hindu Kush Himalayas (HKH) also experienced a temperature rise of about 1.3 degree Celsius during 1951-2014.

Several areas of the Himalayas have experienced a declining trend in snowfall and also retreat of glaciers in recent decades. By the end of the twenty-first century, its annual mean surface temperature is projected to increase by about 5.2 degree Celsius.

The summer monsoon precipitation from June to September over India has also declined by around 6 per cent from 1951 to 2015, with notable decreases over the Indo-Gangetic Plains and the Western Ghats, the report further states.

Kanpur, Jul 11: "The Uttar Pradesh administration has done the right thing by taking action against my son," said an old and feeble Ram Kumar Dubey, father of gangster Vikas Dubey.

The father said his son killed eight police officials and it was an unforgivable sin.

"Had he listened to us, his life would not have ended this way. Vikas never helped us in any way. Due to him, even our ancestral property was razed to the ground. He also killed eight policemen, which is an unforgivable sin. The administration has done the right thing. Had they not done so, tomorrow others would have acted similarly," Ram Kumar said.

"It is the chief minister's duty to protect every individual. The police is an extension of that. He attacked them which cannot be forgiven. I will not even take part in his cremation," he added.

Ram Kumar Dubey said that his only appeal to the government is to allow him entry to his ancestral property now.

Vikas Dubey was cremated at Bhairav Ghat in Kanpur. His wife, younger son and brother-in-law were present and no other member of his family attended the last rites.

Vikas Dubey was arrested by the police in Ujjain on Thursday morning. He was on the run for the last six days and had come to the city to offer prayers at a temple, where he was identified by a security guard.

He was killed in an encounter by the Uttar Pradesh Police earlier today after he "attempted to flee".

The gangster was the main accused in the encounter that took place in Bikru village in Chaubeypur area of Kanpur last week, in which a group of assailants opened fire on a police team, which had gone to arrest him.

Eight police personnel were killed in the encounter.

Vikas Dubey managed to escape after the incident. Uttar Pradesh police had launched a hunt and raised a bounty on him for Rs 5 lakh.

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.
