@Heavenlywarrior Read the article it's science based and not opinion based like your comments. Just because you think a certain way doesn't make it true.
@SW-User @revenant regarding the ozone hole [quote]It's repairing itself because CFC's were banned. It's the greatest environmental treaty that was ever written. And it worked.[/quote] Absolutely true.
The antarctic ozone hole is a case that demonstrates both humanity's ability to affect the atmosphere and humanity's ability to fix the damage we've done. The ozone hole began shrinking when we reduced CFC outputs by over 99%.
[quote]NASA began measuring Earth’s stratospheric ozone layer by satellite in 1979. By the time the Montreal Protocol went into effect in 1989, ozone concentrations (in Dobson units) had declined significantly over the Antarctic, enlarging the ozone hole. [/quote]
The American Chemical Society says: [quote] [b]Chlorofluorocarbons and Ozone Depletion[/b] A National Historic Chemical Landmark . . . “When we realized there was a very effective chain reaction, that changed the CFC investigation from an interesting scientific problem to one that had major environmental consequences,” Rowland told Chemical & Engineering News in an extensive interview in 2007. “You don’t often get many chills down your back when you look at scientific results,” he added, but that had been one of those moments.[/quote] https://www.acs.org/content/acs/en/education/whatischemistry/landmarks/cfcs-ozone.html
Want more? [quote]Research studies in the laboratory show that chlorine (Cl) reacts very rapidly with ozone. They also show that the reactive chemical chlorine monoxide (ClO) formed in that reaction can undergo further processes that regenerate the original chlorine, allowing the sequence to be repeated very many times (a chain reaction). Similar reactions also take place between bromine and ozone.
But do these ozone-destroying reactions occur in the "real world"? All the accumulated scientific experience demonstrates that the same chemical reactions do take place in nature. Many other reactions (including those of other chemical species) are often also taking place simultaneously in the stratosphere. This makes the connections among the changes difficult to untangle. Nevertheless, whenever chlorine (or bromine) and ozone are found together in the stratosphere, the ozone-destroying reactions are taking place.
Sometimes a small number of chemical reactions are so dominant in the natural circumstance that the connections are almost as clear as in laboratory experiments. Such a situation occurs in the Antarctic stratosphere during the springtime formation of the ozone hole. Independent measurements made by instruments from the ground and from balloons, aircraft, and satellites have provided a detailed understanding of the chemical reactions in the Antarctic stratosphere. Large areas reach temperatures so low (less than 80°C, or 112°F) that stratospheric clouds form, which is a rare occurrence, except during the polar winters. These polar stratospheric clouds allow chemical reactions that transform chlorine species from forms that do not cause ozone depletion into forms that do cause ozone depletion. Among the latter is chlorine monoxide, which initiates ozone destruction in the presence of sunlight. The amount of reactive chlorine in such regions is therefore much higher than that observed in the middle latitudes, which leads to much faster chemical ozone destruction. The chemical reactions occurring in the presence of these clouds are now well understood from studies under laboratory conditions that mimic those found naturally in the atmosphere.[/quote]
@SW-User Some people refuse to accept reality and instead feel like the are woke free thinkers for doing that. I think it makes them feel special. There are mountains of data and proof of this very well documted success
SW-User
@JimboSaturn "Free thinkers" like @revenant follow a pattern. They scroll YouTube and TikTok etc. (NEVER MSM 😱) and find videos from psychic podcasters or sth that say something like
“I’m going to connect some dots and I’m going to present you with some information. What you do with this information is up to you.”
This pretty much sums up the approach of all online conspiracy theorists: presenting loaded facts and information, and encouraging you, the free thinker, to piece them together in your mind. It makes you feel smart, and the creator gets to avoid any explicit claims that might get them in trouble.
Then, when you confront said free thinkers, you get “do your own research!” (AKA type conspiracy keywords into Google) and buy the cryptocurrencies they recommend (which they definitely DON'T have a financial stake in) in time for the Great Reset :D
@ElwoodBlues as a taswegian, who grew up under this 'hole in the ozone layer ' i can confidently say that " its no biggie to human skin". Vegetation - yes . Humans - no.
When mankind started to increase and migrate, it affected our skin tone.
This is due to the ammount of sunlight differnt lateral regions on earth get.
Ie: skin exposure to levels of UV light .
And this affects different coloured bodies, ie: Black skin at low or high lattitudes usually suffer from lack of vitamin D due to over protective melanin production. White skin types burn badly at equatroial latitudes due to not enough protective melanin production.
Now take into account that first world humanity spends nearly all its time indoors....and has sunscreen and clothing....this 'concept' is near totally defunct, (except for dark skins at extreme latitudes - still valid, if not more so).
Its a know [b]fact[/b] that the majority of 1st world peoples are highly lacking in vitamin d. (Esp dark skinned people)
Increaed sunlight synthesisation is gonna be good for nearly everyone.
Who started this bullshit idea?🤣
This is bad, BAD, targeted research with no scientific back up. Absolute heresay, idiocracy idealistic projectionism.
@Heavenlywarrior it aint happened becuase it evidently doenst biologically [b]need [/b] to happen yet.
I think i explained this . We dont hunt and gather ALL day any more. We spend like 90%, (if not 99%), of our time indoors now.
We are covered in clothes, hats, shade from buildings, cars we travel in, offices we sit in and homes we live in .....and spf moisturisers.
In fact, if you look it up, we are currently recommended to go outside and spend 20 minites is the sun everyday to boost our Vit D levels to some semblance of normalcy.
Not to mention, the human race is naturally homogenising. Races have been blending for years. In fact, its projected that well all look like spanish asians in a few hundred years if the current trends keep going .😏
Basically taller , fatter Brazilains 😂.
And evolution takes THOUSANDS of years dude. As sapiens we have only been around for about 300 thousand years, (160 thou as homo sapien). And it took at least half, if not 3/4 of that to develop different ethnic traits.
I think you're expecting too much of evolution 😂.
Its cool dude....we ain't gonna crisp up and fry yet.
@Heavenlywarrior You didn't read the article. [quote]The problem, it was thought, is that mummy DNA couldn’t be sequenced. But a group of international researchers, using unique methods, have overcome the barriers to do just that. They found that the ancient Egyptians were most closely related to the peoples of the Near East, particularly from the Levant. This is the Eastern Mediterranean which today includes the countries of Turkey, Iraq, Israel, Jordan, Syria, and Lebanon. The mummies used were from the New Kingdom and a later period, (a period later than the Middle Kingdom) when Egypt was under Roman rule.[/quote]
@Heavenlywarrior I don't know, but I don't think Nordic people were Aryan. Aryan is kind of a catch all term and doesn't have any real significance. I think I have more of Mediterranean Caucasian characteristics. I'm whiter than white but my dad has brown eyes and an olive complexion.
@Heavenlywarrior The obsession with fairness in Asia started from their beginnings. It is trendy to scream colonisation but it is not so. They themselves laugh at this ridiculous idea that it is all because of Whitie.
@Heavenlywarrior I have read that Indians from India were the world's biggest consumers of *brightening* (the term whitening is not allowed in advertising anymore ) cosmetic products per capita while Scandinavians were the biggest consumers of suntanning lotions !
