Oil into Waterways

Ah, the mysterious, ever-present "they"!

The depletion in the "hole" is actually about 200 Dobson units, from a typical value of around 350 in other areas, almost 60%. And in some areas it drops as much as 90%.

What are you talking about? This isn't something I've experienced.

This is a story in your head, not science.

They weren't under the ozone layer hole...

How would you know what their cancer rates were.

 

?
Chlorine and bromine destroy ozone in a chemical process. It's not hard.

The drop off happens when the concentrations of chlorine monoxide increase.

The ozone layer depleted fast during the 80s and 90s, and has improved very slightly since about 2000. Coincidently correlating with our CFC output...

One would have to ignore the evidence available to come to that conclusion.

 

I am glad this California spill is organic stuff, it ought to clean right up and be fine.

Of course these are some of the same people peddling Anthropogenic Global Warming to the ignorant rubes of the world in a planetary conspiracy to steal their hard earned money, while the real threat of Australia replacing the cream in milk goes unnoticed except for Heroes like Barry Groves, PHD. (Any internet claims that he is FOS and his PHD came from a Life Experience PHD diploma mill are based on jealous envy, and his implication that smoking might actually be beneficial to health is to be regarded as an intellectual breakthrough in outside the box PHD type thinking, which is beyond the normal humans ability to understand, so don't hurt yourself trying.)

 

Rastapop, you may want to read a bit closer. I said the "ozone layer", not just ozone. Ozone is itself a naturally unstable molecule and needs nothing in particular to break it down. It is also naturally created by the effect of the sun on the upper atmosphere. The ozone layer is then going to be naturally variable but also cannot be destroyed without a substantial change in our sun or atmosphere.

Now, about anthropogenic ozone depletion if you read close and pay attention you may notice some odd things: such as a US environmental service web page that states that volcanoes can't get their gases high enough into the atmosphere and while one eruption resulted in a 10% boost in chlorine levels it didn't last. Of course they make no mention of the fact that chlorine is among the most reactive of all elements, not as reactive as fluorine but not far off, so it will form compounds, many heavier than air, and make its way ground ward. CFCs are heavier than air and, air traffic aside, get into the environment a lot lower down and with a lot less oomph to get them into the upper atmosphere than with volcanoes, and also in much smaller concentrations (again, air traffic aside) but everyone swears that they can be stirred into the high atmosphere in sufficient quantities even as some of the same may laughably claim gasses from volcanoes don't.

 

Has someone raised a concern that it could be destroyed? I thought were were just discussing depletion of the ozone layer.

While our chlorine and bromine output is high, the ozone layer will suffer reductions.

The ozone layer over the Antarctic won't increase to 1980 levels until 2050.

CFCs are known to reach the stratosphere by direct air samples, so there's no room for conspiracy theories about all those rich, powerful, corrupt climate scientists there.

An argument about what volcanoes don't do is a separate one.

 

Yes, and aircraft were pumping them out a lot closer to the ozone layer and in greater concentrations than your odd air conditioner leak.

Ozone hole was always there, it just was not measured. Until some scientists come along and find a hole and says man made it, ignorance is bliss.

Never let a crisis go to waste, and if there is no crisis, make one up.

 

What a ridiculous claim. Ozone over the Antarctic has always been a bit lower, but not to the huge extent it is now thanks to CFCs.

CFCs have a known and provable effect on ozone. Air samples prove conclusively that they reach the stratosphere.

Where do these conspiracy theorists come from?

 

The chemical mechanism which was so clearly understood as the truth is now being questioned. Many other 'clear scientific truths' of their time have been reversed or debunked when knowledge is modified by empirical evidence about things and the politics change. For example DDT was not the bird killer that we were told, 'silent spring' written to sway opinions and stop the use of DDT also caused million of people to suffer and die from preventable Malaria.

Questioned by whom?! Not by any chemist or physicist.

DDT is highly toxic to birds and humans.

Only unscientific "truths" are debunked by science.

 

If you were to honestly study for yourself these things you might be forced to change your mind, which might be uncomfortable to experience.

 

Ditto.

Note that (unlike you) it isn't a case of me "making up my mind" though, I'm simply writing what science shows to be so.

 

"DDT is highly toxic to birds and humans."

Folks have drunk DDT , to prove it is harmless.

Never let reality get in the way of a good scare story.

 

It's toxic to human foetuses and children undergoing development.

Never let your lack of knowledge prevent you from taking unsubstantiated positions on things you don't understand.
