Scientists: Tonga Volcano Eruption Caused Ozone Hole in Antarctica

The ozone hole over Antarctica opened unusually early this year, and scientists believe… Volcanic eruption According to the American website Space, the disaster Honga Tonga that sent shock waves around the world in January 2022 could be the reason for this.

Ozone experts predicted earlier this year that the explosion, which sent 50 million tons (45 million metric tons) of water vapor into the Earth’s atmosphere, would impact the Earth’s protective ozone layer in the years following the explosion.

Water vapor concentrations in the stratosphere, the second lowest layer of Earth’s atmosphere where the ozone layer is located, increased by 10% as a result of the undersea volcanic eruption.

This, according to Paul Newman, senior scientist for atmospheric sciences at NASA’s Goddard Space Flight Center, has led to “significant cooling” in the stratosphere, which is bad news for ozone levels.

New data from the European environmental monitoring agency Copernicus suggests that the predictions may be correct and that ozone concentrations in Antarctica dropped to record lows in early July.

Copernicus said in a statement that in the 43 years since the beginning of scientific measurements, the initial onset of the destruction of the ozone layer has been recorded only about a dozen times.

The data indicates that the size of the ozone hole in August 2023 is the tenth largest on record. The crater is currently 6 million square miles (16 million square kilometers) in size.

It continues to grow until the end of September when Antarctica begins to warm as spring turns, and it takes until the end of November for the hole to close, but it can last longer than that.

Stratospheric cooling resulting from an increase in the concentration of water vapor in the stratosphere leads to the frequent formation of polar stratospheric clouds, and scientists believe that these strange iridescent clouds that form at altitudes of 9 to 15 miles (15 to 25 kilometers) provide the perfect chemical environment. Ozone-depleting substances (ODS) in the stratosphere to do its destructive work.

Although most of these substances, such as CFCs and HFCs previously used in aerosol sprays and refrigerators, are banned under the 1987 Montreal Protocol, their natural degradation takes decades and their concentrations in the atmosphere are high.

Vincent-Henri Butch, director of the Copernicus Atmospheric Monitoring Service (CAMS), said in a statement that while researchers cannot say for sure whether Honga Tonga is responsible for this year’s above-average ozone depletion, they hope to find more measurements. coming months.

“Our ability to provide 3D analysis and forecasts of ozone at the poles is a powerful way to monitor how ozone holes develop in real time and assess the key drivers behind the observed ones,” Beutsch said.

“It provides insight into how certain events, such as last year’s Hanga Tonga-Hunga Hapai volcanic eruption, will affect the growth of the Antarctic ozone hole this year, which increased the amount of water vapor in the stratosphere.

The number of people vaccinated with the second dose increased by 23 million to 426 thousand 39, and a total of 6 million 886 thousand 744 received the third dose of antiviral vaccine to 61 thousand 121. Those who received the fourth level of reminiscence.

The ministry added that since the first case was reported on March 2, 2020, the weekly “positive, new infections with the virus brought the number of confirmed infections in the Kingdom to one million, 276 thousand 635”. Rate” is approximately 5.6 percent.

Social Unity Minister Dr. Nevin Al-Kabaj began his journey to Alexandria Governorate today, Friday, to launch the campaign.A journey of a thousand kilometersBy opening the “Reproductive Health and Early Detection of Cervical Cancer” clinic, the focus is on early detection of cervical cancer and reproductive health..

The Minister of Social Unity confirmed that the “Thousand Kilometer Journey” is scheduled to start today from Alexandria Governorate and continue for two days, from there to 9 Governorates of Beni Souf, Minya, Assiut and Sohaq. , Qana, Luxor and Aswan for two days in each governorate, and finally its activities will end in Cairo Governorate on January 5th and 6th next year..

Al-Kabbaj added that the trip targets three activities, the first of which is related to awareness, where social pioneers in those governorates will be trained to improve awareness and their medical awareness. The second part of the trip is related to training the medical staff of the clinics. In these governorates, “Reproductive Health and Early Detection of Cervical Cancer” has been prepared, where doctors and nurses will be trained on the use of various family planning methods. and the use of the cervical speculum to ensure the delivery of clinical care with high efficiency through workshops and clinical conferences..

The third part of the campaign is economic empowerment, as a bazaar will be established in each governorate where the campaign travels with the aim of promoting their products to women producers and small enterprises..

Scientists are tracking a tree in Brazil that was thought to have died out 185 years ago

Scientists are tracking a tree in Brazil that was thought to have died out 185 years ago

I retired at 100… A centenarian talks about the importance of “being busy at work” to live a long life.

Madeleine Balto recently retired at the age of 100, having worked for more than 80 years – from the age of 18 to 99. According to a CNBC report, Balto believes work has contributed to his longevity.

Balto says of his previous job: “It kept me busy, and I enjoyed the work… As for retirement, I don’t really like it.”

The Balto family started an electric sign manufacturing business in Chicago, with Madeline responsible for office work. She often interacted with customers and it was her favorite job.

She said: “I loved interacting with people… and I was the only one in the office doing all the office work, so it was fun.” “I loved going to work.”

An 85-year-old Harvard University study found that positive relationships make people happier and help them live longer. For this reason, it is not surprising that Balto places a strong emphasis on the importance of family and friends.

Assistant Professor of Medicine and Genetics and Director of Human Lifespan Studies at the Albert Einstein Institute for Aging Research, Dr. Sophia Melman says. College of Medicine.

At 100, Balto maintains his sense of community by going out to dinner with his sons and attending family events. Finally attended a wedding earlier this month.

She also likes going to the Dunkin’ Donuts branch every Sunday with her son to meet friends. “I look forward to it every week,” he says.

Balto affirms that she is lucky; Because she has some friends of the same age who often come to her house for lunch.

She added: “They always invite me over and come over for lunch on Wednesdays at 12pm… we have fun together… without your friends, where are you, right?”

While maintaining healthy relationships is an important factor in living longer, there are other factors that contributed to Balto’s longevity.

First, Mellman says, “In general, women’s life expectancy is longer than men’s…and we believe that genetics also has a significant relationship with longevity.”

In fact, Balto’s older sister lived to be 103 years old. “But she and I are the only ones who lived over 100 years,” she says, referring to her parents, who died at 84, and her sisters, who didn’t live very long.

I grew up on a vegetarian diet

Aiming to stay active, Balto says, “I’m still getting around better. I can walk up the stairs. I have energy; “so I’m in pretty good shape.”

She also tries to eat as healthy as possible, something that started in her childhood, she explains: “When I was a child, there were seven children in the family, and my father was building a big garden, so we lived mostly. On vegetables. “There wasn’t a lot of meat, we couldn’t afford meat.”

“I think that’s probably why I eat healthier,” she adds. Don’t eat fast food now.

Millman says centenarians are generally more confident, and Balto fits that description. He says it’s unclear whether centenarians are always positive, or whether they develop their positive outlook as they age.

Balto says she doesn’t feel too nervous; Because “everything can be solved.” She continues: “I’m very lucky; As I am 100 years old, I am in good health… I cannot complain about my health. “I’m walking, talking, no pain.”
