India's Agni long-range missiles broke UN limits, says China

Prayagraj,  April 1: Seven Indonesian nationals, one person from Kolkata and one from Kerala who had attended the event at Delhi's Nizamuddin Markaz have been put under quarantine, informed SP (City) Prayagraj, Brijesh Kumar Srivastava on Wednesday.

"Seven Indonesian nationals, one person from Kolkata and one from Kerala, were found at Abdullah mosque here. During the investigation, it was found that they had attended the Markaz gathering in Delhi. These people, along with 28 people who came in contact with them, have been quarantined." he said.

"A case has also been registered against them for not informing the police on reaching here," he added.

Earlier, Delhi Health Minister Satyendar Jain had said that the officials are not certain of the accurate number of people who participated in the event but it is being estimated that 1,500-1,700 people had assembled at the Markaz building.

The religious gathering was held at the Markaz building in Nizamuddin between March 13 and March 15.

The total number of active cases rose to 1466 in the country, while 132 people have been cured and discharged after receiving treatment, as of 9 am.

The number of deaths due to the infection also rose to 38, while one person has migrated.

New Delhi, Jul 18: The Covid-19 lockdown-led reduction in air pollution levels across five Indian cities, including Delhi and Mumbai, may have prevented about 630 premature deaths, and saved USD 690 million in health costs in the country, according to a new study.

Scientists, including those from the University of Surrey in the UK, assessed the levels of harmful fine particulate matter (PM2.5) from vehicles and other sources in five Indian cities -- Delhi, Mumbai, Kolkata, Chennai and Hyderabad -- since the beginning of the lockdown period.

The study, published in the journal Sustainable Cities and Society, compared these lockdown PM2.5 figures from 25 March up until 11 May, with those from similar periods of the preceding five years, and found that the measure reduced pollution levels in all these places.

According to the scientists, during this period, the levels of these harmful air pollutants reduced by 10 per cent in Mumbai, and by up to 54 per cent in Delhi.

"The percentage reduction for the other cities ranged from 24 to 32 per cent, which was slightly smaller than the measured values for Delhi and Mumbai," the scientists noted in the study.

"While the reduction in PM2.5 pollution may not be surprising, the size of the reduction should make us all take notice of the impact we have been having on the planet," said Prashant Kumar, a co-author of the study from the University of Surrey.

The scientists said these reductions in PM2.5 were comparable to those reported in other cities across the world, such as in Austria's capital Vienna (60 per cent), and Shanghai (42 per cent) in China.

They also calculated the monetary value of the reduced mortality due to air pollution and found that the lowered levels of PM2.5 may have saved 630 people from premature death, and USD 690 million in health costs in India.

According to the researchers, the present lockdown situation offers observational opportunities regarding potential control systems and regulations for improved urban air quality.

They said an integrated approach might help in understanding the overall impacts of Covid-19 lockdown-style interventions and support the implementation of relevant policy frameworks.

"This is an opportunity for us all to discuss and debate what the 'new normal' should look like - particularly when it comes to the quality of the air we breathe," Kumar said.

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.
