No, it's not natural. CFC-11 is fluorotrichloride, or CFCl3. C-Cl and C-F bonds are artificial- in nature you don't see them much. To form them you need to invest energy, because you're starting with ionic chlorides and fluorides, which are not terribly interested in forming covalent bonds with a non-metal like carbon. That's why these chemicals fall apart so easily when they reach the upper stratosphere. The fluorine doesn't stick around for long, but the chlorine with the unpaired electron attacks ozone and survives the encounter. A single chlorine radical will destroy billions of ozone molecules for the two years it spends in the air. It attacks its first ozone to form ordinary oxygen and chlorine monoxide, which still has an unpaired electron. The chlorine monoxide attacks a second ozone, yielding more oxygen and releasing the chlorine radical to kill again. Although the chlorine radical itself only lasts a few decades, its fluorotrichloromethane precursor hangs around for decades to replenish the supply.

The fact that the molecule has four of these weird bonds makes it really suspicious. Someone is definitely making this shit.

Trump on the issue of CFCs... https://www.youtube.com/watch?...

I remember getting into an argument here about four years ago about this problem with Bitcoin- that "mining" coins is based on everyone racing to use as much electricity as possible, and the number of kilowatt-hours burned per generated coin increases with time, as part of the design. "ATMs use electricity too" was the consensus opinion.
Now we have a "currency" that gets "mined" using more electricity than Ireland uses. The wattage devoted to this crap has increased sevenfold during the past 12 months. People only use it as an investment, making it useless as a currency. "Everyone accepts it as payment" doesn't mean anything when everyone who has it is too scared to spend it.

The issue is that you're also persisting the methods, not just the fields.

So we're all clear - "petrified" as in "turned to stone" not "terrified", right?

I found myself wondering about that several years after the fact - one is a joke,the other is *really* creepy.

I always understood "turned to stone" myself.

Only if she is naked and petrified.

RIP RobLimo .FWIW, your work touched a lot of lives. And in a good way, not a JonKatz sort of way.

As long as they stick to trolling, they can't do much more damage than they already have. At this point, you're either aware of them, or your mind is already in an alternate universe where kids get molested in nonexistent pizzeria basements by a presidential candidate who fits the typical pedo demographic to a "T". (Although I think I missed the episodes of To Catch a Predator where elderly female politicians arrive at the door with pizzas.)

The Russians would get more payoff at this point from cyberattacking the electrical grid on Election Day. But those who are in a position to prevent this don't seem to mind the trolling at all.

I know, it's so easy. Just add an "I have HIV" checkbox to your dating site that hides the rest of the page when checked, thus preventing the HIV positive user from accessing the site.

Problem solved!

According to court precedent, a baker has to bake a cake for a gay wedding. But they cannot require him to ice it with "God is dead". If a white supremacist couple comes into a Jewish bakery they must be served, but they can't require swastika icing.
Youtube is a private company, not some sort of public square or civic space that must accommodate free expression in all forms. They offer an equal platform to everyone no matter what their political persuasion. (Being a private entity, they're not required to, but they do.) But if you upload nothing but crap, and they decide it's crap, they have the right to kick you out. Unless the cops show up to arrest you because someone didn't like the politics in your videos, no U.S. court will consider your First Amendment rights to have been infringed. They'll just say you can upload your videos somewhere else if you don't like it.

Carbon dioxide begins to affect human cognition and decision-making ability at around 600 ppm. It's a problem in newer energy-efficient buildings; some companies are beginning to install CO2 scrubbers in their ventilation systems to boost productivity.

I remember when Asteroids came out in the early 80s. I went into a demented state and fired lasers at space rocks.

Why is this marked Troll?
A lot of Silicon Valley companies have convinced themselves that they run some sort of civic space where all "viewpoints" must be tolerated long past the point where cops in a public square would have been busting heads.
It's a private company in an unregulated market. None of your tax dollars go to it, your First Amendment rights do not trump their own, and alternatives to them are available. It's their right and in their interests to maintain a proper signal-to-noise ratio. Believe it or not, people stop visiting web sites when they begin to resemble landfills, so it's in the site's interest to purge you if you upload horseshit.
If you don't like Twitter, move to Gab- a site where I would naturally expect to get kicked off. If Youtube deletes your video, upload it somewhere else. If you don't like it, deprive it of your content and see if anyone cares enough to follow you.

When will this worthless shit crash already? It's a complete failure as a currency. All it's accomplished for the world is to facilitate trafficking in drugs, weapons, and humans, and to reward people who waste electricity. Yes, everyone accepts it as payment. Because it's undergoing a bubble. But no one wants to pay for stuff with it. Because it's undergoing a bubble.

For a currency to be usable, it needs to maintain a stable value. Bitcoin fails miserably at it. Nerds seem to get intrigued by its algorithm and lose sight of human nature- people won't trust it once they get burned by the crash that's being dismissed as an inevitable "short-term correction". (And that's more acceptable than a long-term correction... why?) Sure, you'll forget you were a "billionaire" when you went to bed last night and you'll buy pizza with your Bitcoins for lunch- except no pizzeria will accept them after that. But rest assured, there is a distributed blockchain uncontrolled by any central authority that establishes beyond all doubt that you are the proud owner of a worthless currency.

Bitcoin has made one thing perfectly clear- so-called "fiat money" is the worst kind of currency except for all the others.

What most people don't know is, Sonny Bono actually had some sort of music career before he became a corrupt politician. Did you know that? I knew that. Most people don't know that. Because everyone just knows him as the guy who came up with the Sonny Bono Copyright Term Extension Act. But he was actually a singer. He died skiing when he hit a tree; once the tree has seventy more rings I'll check out his albums.

Everyone knows the Chinese steal intellectual property; why wouldn't they be pirating dinosaur DNA?

I wouldn't give these eggs to Daenerys Targaryen as presents; she'd walk out of the fire with dragons that flop over as soon as she tells them to fly.
