The hole in the ozone layer is smaller than ever, NASA says

The hole in the ozone layer is smaller than ever, NASA says

In some double-edged news for the planet, NASA has recently announced that the hole in the ozone layer has shrunk to its smallest size since it was detected in the mid-1980s. But there's a bit of a catch as to why it shrank in the first place, and yes it has to do with climate change.


Back in the days of glam rock and unlimited hairspray most people were totally oblivious to the damage they were doing to the atmosphere. Then in 1985 a group of buzz killers (a.k.a. scientists) released findings that showed the ozone levels in the atmosphere over the poles were depleting at an alarming rate.

And suddenly certain real estate moguls had to find another way to make the remnants of their hair bend in an unnatural direction, and proving that anyone can be a victim of their own ignorance.

The ozone layer is a part of the Earth's atmosphere made up of molecules called, wait for it, ozones! Which are basically triple strength oxygen - where the oxygen molecules we breath are made up of two oxygen atoms, the ozone layer molecules have three oxygen atoms.

And throughout Earth's history these brave tiny soldiers stood guard against the sun's radiation, specifically UV rays which are known to cause skin cancer. But when we found that they were being killed off, well, you can see how that could raise some obvious concerns. Please enjoy this nifty video from The National Geographic to learn more!

In the decades since the substances that caused the depletion were banned or prohibited (see: the Montreal Protocol) the ozone layer has shown signs of rebounding.

Recently NASA released a report that said the ozone hole was the smallest it has been since it was discovered, stretching to 3.9 million square miles. That may sound like a lot but it's actually half the usual size around this time of year which is around 8 million square miles.

This is all pretty good long-run news for the planet, but, and yes this the big "but," there's a caveat. "It's great news for ozone in the Southern Hemisphere," said Paul Newman, chief scientist for Earth Sciences at NASA's Goddard Space Flight Center. "But it's important to recognize that what we're seeing this year is due to warmer stratospheric temperatures. It's not a sign that atmospheric ozone is suddenly on a fast track to recovery."


It's true, and shrinking of the ozone has actually happened in the past though not quite to this degree, but it was always due to strange weather patterns. And scientist are still investigating, however the main culprit for this seems to be rising global temperatures.

"It's a rare event that we're still trying to understand. If the warming hadn't happened, we'd likely be looking at a much more typical ozone hole." Said Susan Strahan, a researcher with the Universities Space Research Association.

Despite this however, scientists are optimistic that by 2070, at current rates the ozone layer can return to normal.

Finally, someone explains why we all need subtitles

It seems everyone needs subtitles nowadays in order to "hear" the television. This is something that has become more common over the past decade and it's caused people to question if their hearing is going bad or if perhaps actors have gotten lazy with enunciation.

So if you've been wondering if it's just you who needs subtitles in order to watch the latest marathon-worthy show, worry no more. Vox video producer Edward Vega interviewed dialogue editor Austin Olivia Kendrick to get to the bottom of why we can't seem to make out what the actors are saying anymore. It turns out it's technology's fault, and to get to how we got here, Vega and Kendrick took us back in time.

They first explained that way back when movies were first moving from silent film to spoken dialogue, actors had to enunciate and project loudly while speaking directly into a large microphone. If they spoke and moved like actors do today, it would sound almost as if someone were giving a drive-by soliloquy while circling the block. You'd only hear every other sentence or two.

Man hailed 'Highway Hero' for running across four lanes of traffic

Holy cow, Bat Man! You're always supposed to be aware of other vehicles when you're driving but what do you do when you notice someone has lost consciousness while speeding down the highway?

It's a scenario that no one wants to see play out, but for Adolfo Molina, the scenario became reality and he didn't hesitate to spring into action. Molina was driving down the highway when he spotted a woman in a blue car who lost consciousness as her car careened down the shoulder of the highway. The concerned driver quickly pulled over in order to attempt to rescue the woman.

But there was a problem, he had to cross four lanes of traffic on the highway just to make it to the woman's still moving car. That obstacle didn't stop him. Molina sprinted across the highway, crossing right in front of a black pick up truck before running at full speed to attempt to open the woman's door and stop her car.

Pennsylvania home is the entrance to a cave that’s been closed for 70 years

You can only access the cave from the basement of the home and it’s open for business.

This Pennsylvania home is the entrance to a cave.

Have you ever seen something in a movie or online and thought, "That's totally fake," only to find out it's absolutely a real thing? That's sort of how this house in Pennsylvania comes across. It just seems too fantastical to be real, and yet somehow it actually exists.

The home sits between Greencastle and Mercersburg, Pennsylvania, and houses a pretty unique public secret. There's a cave in the basement. Not a man cave or a basement that makes you feel like you're in a cave, but an actual cave that you can't get to unless you go through the house.

Turns out the cave was discovered in the 1830s on the land of John Coffey, according to Uncovering PA, but the story of how it was found is unclear. People would climb down into the cave to explore occasionally until the land was leased about 100 years later and a small structure was built over the cave opening.

Relationship expert tells people to never get married unless you're willing to do 3 things

"If you and your partner (both) are unable or unwilling to do these 3 things consistently forever, you won’t make it."

Relationship expert gives people advice on getting married.

Being in a relationship can be difficult at times. Learning someone else's quirks, boundaries, and deep views on the world can be eye-opening and hard. But usually, the happy chemicals released in our brain when we love someone can cause us to overlook things in order to keep the peace.

Jayson Gaddis, a relationship expert, took to Twitter to rip off people's rose-colored glasses and tell them to forego marriage. Honestly, with the divorce rate in this country being as high as it is, he probably could've stopped his tweet right there. Don't get married, the end. Many people would've probably related and not questioned the bold statement, but thankfully he followed up with three things you must be willing to do before going to the chapel.

Before going into his reasons for why he tells people not to get married, Gaddis explained that he is a person that "LOVEs being married." I mean, it would probably make him a pretty weird relationship expert if he hated relationships, so it's probably a good thing he enjoys being married. Surely his spouse appreciates his stance as well.

Humanitarian Helen Keller circa 1920.

In a 1954 documentary short, humanitarian Helen Keller expressed that her greatest regret in life was being unable to speak clearly. But given that she could not see or hear, her speech was quite remarkable.

Keller was born in 1880 and, at the age of 18 months, contracted an unknown illness that left her deaf and blind. But with the help of her teacher, Anne Sullivan, she was able to overcome her disabilities and become an outspoken advocate for the voiceless and oppressed.

10 years ago, a 'Stairway to Heaven' performance brought Led Zeppelin's surviving members to tears

Heart, John Bonham's son and a full choir came together for the epic tribute.

Led Zeppelin got to see their iconic hit performed for them.

When Billboard and Rolling Stone pull together their "Best Songs of All Time" lists, there are some tunes you know for sure will be included. Led Zeppelin's "Stairway to Heaven" is most definitely one of them.

It has everything—the beauty of a ballad, the grunginess of a rock song, the simple solo voice, and the band in full force. "Stairway to Heaven" takes us on a musical journey, and even people who aren't necessarily giant Led Zeppelin or classic rock fans can't help but nod or sing along to it.

Of course, it's also been so ubiquitous (or overplayed, as some would claim) to become a meme among musicians. Signs saying "No Stairway to Heaven" in guitar stores point to how sick of the song many guitarists get, and when Oregon radio station KBOO told listeners they would never play the song again if someone pledged $10,000, Led Zepelin singer Robert Plant himself called in and gave the donation.
