“An ozone hole, seven times larger than the Antarctic ozone hole, is currently sitting over tropical regions and has been since the 1980s, according to a Canadian researcher.

In AIP Advances, Qing-Bin Lu, a scientist from the University of Waterloo in Ontario, Canada, reveals a large, all-season ozone hole—defined as an area of ozone loss larger than 25% compared with the undisturbed atmosphere—in the lower stratosphere over the tropics comparable in depth to that of the well-known springtime Antarctic hole, but its area is roughly seven times greater.

"The tropics constitute half the planet's surface area and are home to about half the world's population," said Lu. "The existence of the tropical ozone hole may cause a great global concern.

"The depletion of the ozone layer can lead to increased ground-level UV radiation, which can increase risk of skin cancer and cataracts in humans, as well as weaken human immune systems, decrease agricultural productivity, and negatively affect sensitive aquatic organisms and ecosystems."

Lu's observation of the ozone hole comes as a surprise to his peers in the scientific community, since it was not predicted by conventional photochemical models. His observed data agree well with the cosmic-ray-driven electron reaction (CRE) model and strongly indicate the identical physical mechanism working for both Antarctic and tropical ozone holes.

As with the polar ozone hole, approximately 80% of the normal ozone value is found to be depleted at the center of the tropical ozone hole. Preliminary reports show ozone depletion levels over equatorial regions are already endangering large populations and the associated UV radiation reaching these regions is far greater than expected.

In the mid-1970s, atmospheric research suggested the ozone layer, which absorbs most of the sun's ultraviolet radiation, might be depleted because of industrial chemicals, primarily chlorofluorocarbons (CFCs). The 1985 discovery of the Antarctic ozone hole confirmed CFC-caused ozone depletion. Although bans on such chemicals have helped slow ozone depletion, evidence suggests ozone depletion persisted.

Lu said the tropical and polar ozone holes play a major role in cooling and regulating stratospheric temperatures, mirroring the formation of three "temperature holes" in the global stratosphere. He said this finding may prove crucial to better understanding global climate change.

Lu's discovery builds on previous studies of the CRE-initiated ozone-depleting mechanism that he and his colleagues originally proposed about two decades ago.

"The present discovery calls for further careful studies of ozone depletion, UV radiation change, increased cancer risks, and other negative effects on health and ecosystems in the tropical regions," said Lu.

were f***ed bro im not putting kids into this world

Pack it the f*** up !

these o’s ain’t loyal

😔

which planet we going to ruin next fam? neptune looks lit

its alright guys, imma close the hole with my d***

this just means pretty soon we going to be wearing this type of s*** & look like clout chasers from LA

i don’t know what’s worse - don’t look up alternate sequel - world ending or we end up being forced to become cosplay hype beast boba fetts

😒

Y'all talking like we gonna ruin earth

Y'all must have it mistaken

Earth about to ruin us

Dinosaurs lived for millions of years. MILLIONS. Humans? Just a few hundred thousand.

We will be wiped off this planet because of our hubris but the earth will survive. And something new will come. Something that won't even know we ever existed.

After a few eons, something may find our indestructible left overs under layers of compressed rock and clay if they ever understand earth the way we did. And our failures will serve as a cautionary tale.

Makes me scared but I really hope to be long dead before society and civilization falls and the earth swallows us. And I hope reincarnation doesn't exist so I don't be rebirthed in a time where my conscience can experience it.

tell em @Fka_Groovy

likewise im hoping for a slow collapse so I can just have an peaceful life and yeah ion wanna be reborn f*** no

Yeah our generation bout to be the last one to enjoy anything "peaceful" with nature and the planet.

smells like cap for more funding

ozussy

this is what they want you to believe

Damnit mr President look what you’ve done now

It's cause people in the western world dumb as s***

They don't see it directly so they don't care, while we the ones w the biggest emissions. Other parts of the world, like in the pacific and Africa, already having huge climate problems and getting f***ed over it

reminder we used to be in an ice age this stuff happens im using plastic bags at the grocery store

Whether you believe this is a concern or not, why keep polluting though? We need to eat off this planet, why ruin it at the same time?

Cause he one of the dumb f***s i just mentioned

paper bags used to be the norm then they invented plastic and said use this because we are cutting down too many trees now they want me to go back to tree bags?

Fr ppl be overdramatic

It is a propaganda war on these issues I agree

Paper used to be made an enemy back from 2008 - 2012, so all these companies made up e-friendly options. However years later, it was proven that these companies lied for profits and were f***ing over paper companies.

However, on the opposite end, oil companies created "carbon footprints" and shifted all the polluting blame onto the consumer instead of the oil companies themselves.

Not really at all, we ARE going to ruin the earth for the status quo type living we have gotten accustomed to. This is a fact.

We are not going to ruin life on earth or the earth in general. Life finds a way.
