Report shows the ozone layer is rapidly repairing itself faster than anyone imagined

The world came together in to solve the problem. Let's do it again.

There are many reasons to worry about climate change's effects and whether the world’s leaders are brave enough to make the bold decisions necessary to abate the growing crisis. But a new report from the United Nations shows that when people come together and follow the science, it’s possible to stop environmental disasters before they happen.

An executive assessment from the UN has found that the hole in the Earth’s ozone layer is on track to be completely healed within the next two decades. If current policies remain in place, the ozone layer should recover to 1980 levels by around 2066 in the Antarctic, 2045 in the Arctic and 2040 throughout the rest of the world.

The hole was first discovered by scientists in 1985 above Antarctica and it caused immediate worry. According to Discover magazine, the ozone layer acts as the planet’s sunscreen and without it, we’d be exposed to harmful ultraviolet rays that cause skin cancer and cataracts. The radiation is also harmful to marine life and plants and would cause a major disruption to the world’s food supply.


“In the upper stratosphere and in the ozone hole we see things getting better,” Paul A. Newman, co-chair of the scientific assessment panel of the Montreal Protocol, said according to the Associated Press. He added that the two biggest contributors to the hole, chlorine and bromine, have dropped from their peaks in the '90s.

That bromine and chlorine levels “stopped growing and is coming down is a real testament to the effectiveness of the Montreal Protocol,” Newman said.

The Montreal Protocol is an international agreement signed in 1989 that helped eliminate 99% of ozone-depleting chemicals including chlorofluorocarbons (CFCs). At the time, these were found in spray cans, refrigerants and air-conditioning units.

Although much of the world has stopped using CFCs, they can linger in the atmosphere for a century.

“The protocol marks an important milestone for the future quality of the global environment and for the health and well-being of all peoples of the world,” former President Ronald Reagan said after the agreement was signed in 1988. “Unanimous approval of the protocol by the Senate on March 14th demonstrated to the world community this country's willingness to act promptly and decisively in carrying out its commitments to protect the stratospheric ozone layer from the damaging effects of chlorofluorocarbons and halons, but our action alone is not enough.”

“It’s a bit like waiting for paint to dry, you just have to wait for nature to do its thing and flush out these chemicals,” David Fahey, a scientist at National Oceanic and Atmospheric Administration, said according to The Guardian.

If political leaders hadn’t taken action back in the '80s, we would be having some serious problems in 2023. World leaders should take the positive lessons learned by the fight against ozone depletion and use them toward fixing climate change before it becomes irreversible.

Unfortunately, the fight against climate change is more difficult because greenhouse gasses stay in the atmosphere much longer than CFCs and asking people to change their refrigerants is a lot easier than asking them to stop driving cars.

“CO2 is another order of magnitude when it comes to its longevity, which is sobering,” Fahey said. “Getting every person on the planet to stop burning fossil fuels is a vastly different challenge.”

True

If you’ve always lived in a world with social media, it can be tough to truly understand how it affects your life. One of the best ways to grasp its impact is to take a break to see what life is like without being tethered to your phone and distracted by a constant stream of notifications.

Knowing when to disconnect is becoming increasingly important as younger people are becoming aware of the adverse effects screen time can have on their eyes. According to Eyesafe Nielsen, adults are now spending 13-plus hours a day on their digital devices, a 35% increase from 2019.1. Many of us now spend more time staring at screens on a given day than we do sleeping which can impact our eye health.

Normally, you blink around 15 times per minute, however, focusing your eyes on computer screens or other digital displays have been shown to reduce your blink rate by up to 60%.2 Reduced blinking can destabilize your eyes’ tear film, causing dry, tired eyes and blurred vision.3

There are many way to invest in your future

Eighteen year old Samantha Frye has traded college life for entrepreneurship, and she has no regrets.

Things you would tell your 13-year-old self

There are so many times we look back on our lives and think about things we would change or do slightly differently. But many people say they wouldn't change anything because it would change who or where they are in their life now. The mystery around changing something that happened in the past is so woven into our psyches that there are entire sci-fi genres around time travel and what would happen if you altered the past.

While science fiction movies like "The Butterfly Effect" warn us against tampering with events of the past no matter how small, it doesn't stop people from wondering. A user on Reddit decided to pose a question asking what three words you'd tell your 13-year-old self, and some of the answers were surprisingly heartbreaking. (At 13, you'd think most people would want to tell themselves something silly, like the user who wrote, "Pull my finger.")

13-year-old uses a slingshot to rescue his little sister from being abducted

He had two projectiles and both hit the suspect, forcing him to drop the little girl.

Owen Burns, 13, rescued his sister from a would-be abductor using a slingshot.

A parent never wants to imagine what would happen if their child were confronted with someone meaning them harm. We do everything in our power to mitigate the risks of things like that happening, but scary situations still occur that can leave a family irreparably broken.

A Michigan family had an extremely close call when their 8-year-old daughter was nearly abducted while playing in their backyard. The little girl was outside picking mushrooms when a 17-year-old boy picked her up with his hand over her mouth. Owen Burns, 13, was inside playing video games when he heard his sister scream. A lot of kids in his situation may not have known what to do, but Owen quickly jumped into action.

The teen saw what was happening out the window and picked up his slingshot and a marble before taking aim at the boy who had his sister.

She is simply the best.

The explosive, soulful, magnetic Tina Turner has died at 83. Though the cause of her death was not disclosed, a statement on her Instagram announced that the prolific singer and legendary live performer has passed away at her home in Küsnacht, Switzerland, near Zurich.

News of the devastating loss has prompted an outpouring of tributes on social media, including celebrities sharing how much Turner’s work has influenced them.

Angela Bassett, who portrayed the music icon in the 1993 biopic “What's Love Got to Do with It,” said in a statement that she was "honored to have known Tina Turner."

"Through her courage in telling her story, her commitment to stay the course in her life, no matter the sacrifice, and her determination to carve out a space in rock and roll for herself and for others who look like her," Bassett wrote on Instagram, "Tina Turner showed others who lived in fear what a beautiful future filled with love, compassion, and freedom should look like."

Everyone's childhood is different. But there are common objects, sights, sounds, smells, and memories from elementary school that most Gen Xers and Millenials share.

Personally, when i think back to being in elementary school in the '80s, I remember the taste of the chocolate ship cookie we got on Fridays (with the pizza). The humiliation of getting nailed in the back during nation ball. And the grumbling, grinding sound that happened when you slipped a disk into the drive on an Apple IIe computer.

Women are shocking their boyfriends by showing them how  tampons actually work

The viral videos are a great way to educate men on a sensitive topic.

via TikTok

Menstrual taboos are as old as time and found across cultures. They've been used to separate women from men physically — menstrual huts are still a thing — and socially, by creating the perception that a natural bodily function is a sign of weakness.

Even in today's world women are deemed unfit for positions of power because some men actually believe they won't be able to handle stressful situations while mensurating.

"Menstruation is an opening for attack: a mark of shame, a sign of weakness, an argument to keep women out of positions of power,' Colin Schultz writes in Popular Science.
