Unusual mini-ozone hole opens over the Arctic

Mini Ozone Hole

London, April 10 : As the world fights the new coronavirus pandemic, climate change is back to threaten us as over the last month, a new unusual hole in the ozone layer has started to form over the Arctic.

According to the European Space Agency, the ozone layer over the North Pole has been depleted plenty of times in the past.

Scientists using data from the Copernicus Sentinel-5P satellite have noticed a strong reduction of ozone concentrations over the Arctic.

Unusual atmospheric conditions, including freezing temperatures in the stratosphere, have led ozone levels to plummet — causing a ‘mini-hole’ in the ozone layer, the ESA said in a statement.

While the ESA scientists expect it to close up later this month, it’s a troubling update on the planet’s environmental health.

The ‘ozone hole’ most commonly referenced is the hole over Antarctica, forming each year during autumn.

In the past weeks, scientists from the German Aerospace Center (DLR) have noticed the unusually strong depletion of ozone over the northern polar regions.

Using data from the Tropomi instrument on the Copernicus Sentinel-5P satellite, they were able to monitor this Arctic ozone hole form in the atmosphere.

“The ozone hole we observe over the Arctic this year has a maximum extension of less than 1 million sq km. This is small compared to the Antarctic hole, which can reach a size of around 20 to 25 million sq km with a normal duration of around 3 to 4 months,” said Diego Loyola from the German Aerospace Center.

Arctic temperatures do not usually plummet as low as in Antarctica. However, this year, powerful winds flowing around the North Pole trapped cold air within what is known as the ‘polar vortex’ — a circling whirlpool of stratospheric winds.

By the end of the polar winter, the first sunlight over the North Pole initiated this unusually strong ozone depletion — causing the hole to form.

However, its size is still small compared to what can usually be observed in the southern hemisphere, informed ESA.

Claus Zehner, ESA’s Copernicus Sentinel-5P mission manager, said: “The Tropomi total ozone measurements are extending Europe’s capability of the continuous global ozone monitoring from space since 1995. In this time, we have not witnessed an ozone hole formation of this size over the Arctic.”

In the past, mini ozone holes have occasionally been spotted over the North Pole, but the depletion over the Arctic this year is much larger compared to previous years.

Narendra Modi

New Delhi, Jan 25 : Prime Minister Narendra Modi at Climate Adaptation Summit 2021 said that India has not just promised to meet their Paris Agreement targets instead exceed them.

He further informed that India is targeting 450 Gigawatt of renewable energy capacity by 2030 and also promoting LED lights and savings 38 millions of tons of CO2 emissions annually.

PM Modi said, “Climate adaptation is more significant today than ever before and it is a key element for India’s development efforts. We have promised ourselves that we will not just meet our Paris Agreement targets but exceed them. We will not just arrest environment degradation but will reverse it. Our action shows our commitment. We are targeting 450 Gigawatt of renewable energy capacity by 2030. We are promoting LED lights and savings 38 millions of tons of CO2 emissions annually. We are going to restore 26 million hectares of degraded land by 2030.”

Cow in India

New Delhi, Jan 12 : Union Minister Nitin Gadkari on Tuesday launched the ‘Khadi Prakritik Paint’ here and said that bulk utilisation of cow dung will ensure monetory gains for farmers and put a check on cow slaughter in the country.

He made the remarks while launching the Khadi Prakritik Pain along with Union Minister for Fisheries, Animal Husbandry and Dairying, Giriraj Singh.

Speaking on the occasion, Gadkari said, “The innovative Khadi Prakritik Paint has the potential of turning into a Rs 6,000 crore market that could revolutionalise the agro-based economy of the country.”

He said that at least five crore new jobs will be created in the MSME sector and the export of Indian MSMEs will be increased from current 48 per cent to 60 per cent in order to achieve the target of $5 trillion dollar economy.

“Very soon a policy will be framed for sharing the technical knowhow of Khadi Prakritik Paint to maximum number of people in India,” he said, adding that Khadi and Village Industries Commission (KVIC) will provide technical training to new entrepreneurs who could benefit by manufacturing cow dung paint.

He said that thousands of Prakritik paint manufacturing units can be set up across the country that will give a big boost to the country’s agro-based economy.

Gadkari said bulk utilisation of cow dung will ensure monetary gains for farmers and will also desist them from selling cows in the market.

“This will also put a check on cow slaughter. We will be able to stop cow slaughter through economy,” he said.

Minimum temperature to fall 3-4 degree over NW India

The Met Department also confirmed that there will be “no significant change in minimum temperatures over rest parts of the country during next 3-4 days”.

Cold Winter Weather

New Delhi, Jan 10 : Minimum temperature is very likely to fall gradually by three-four degree Celsius during next three-four days, causing isolated cold wave conditions over Punjab, Haryana, Chandigarh, Delhi and north Rajasthan on January 12 and 13, the IMD said on Sunday.

Prevalence of dry north or northwesterly winds over most parts of northwest India is learnt to be the reason behind the temperature fall, said India Meteorological Department (IMD) in its latest weather summary report.

As per the IMD, strong surface winds with 15-25 kmph speed are very likely over the plains of northwest India during next three days.

“Gradual fall in minimum temperatures by 3-4 degree Celsius very likely over most parts of northwest India during next 3-4 days and rise by 2-3 degree Celsius during subsequent 2-3 days over the same region. Fall in minimum temperature by 3-5 degree Celsius over most parts of central and east India during next 3-4 days and by 2-3 degree Celsius over west India during next 2-3 days and no significant change thereafter,” the IMD forecast.

The Met Department also confirmed that there will be “no significant change in minimum temperatures over rest parts of the country during next 3-4 days”.

Meanwhile, shallow to moderate fog in isolated pockets is very likely over Telangana, Odisha and sub-Himalayan West Bengal and Sikkim on January 11, over Jharkhand on January 11-12 and over northeast India during next 5 days.

Under the influence of the cyclonic circulation over equatorial Indian Ocean and adjoining central parts of South Bay of Bengal up to mid tropospheric levels, fairly widespread to widespread rainfall with moderate thunderstorm and lightning is very likely over Tamil Nadu, Kerala and Lakshadweep during next three days, the IMD said.
