Why is the ozone hole bigger than it was 20 years ago when the chemicals they blamed it on were banned?

Question

Unless maybe it's not as simple as they made it out to be....

Good point - there's rarely an explanation of the prior contradictory theory. Almost never a good one. It's always "oh, forget that, believe us now."

Jacob it remains the case that the level of concentration has declined precipitously and that the levels of new CFC production have dwindled by over 90% - - yet the problem not only persists but gets worse.

The official explanation is that well, the effects of the pre-ban CFCs were even greater than we thought - i.e., big bad capitalism was so bad, the badness it caused still exists and grows today.

Doesn't that sound just a bit like Animal Farm to you?

Margaret again, the link provided would seem to indicate that the problem should be on the wane, but it isn't. Yes some countries still use CFCs but global production is less than 1/10th of what it was, and atmospheric CFC levels and levels of its components are declining - - the problem should at the very least not be getting worse.

It seems pretty clear that while CFCs may be a factor, it's not as cut and dried as the pictorial indicates, and that gets back to my issue - - - - even if you're sure that the gist of something is true, if the message sweeps seemingly contradictory items under the rug (AGW/MWP) rather than explaining them, or exaggerates (teflon birds) or just plain lies (Monsanto butterflies), why is it any wonder that there are so many skeptics?

Do the greenies not have only themselves to blame?

Answer 1

Don't confuse people with the facts now. Global warming was soot and pollution in the 1980's, the hole in the ozone in the 1990's... now its carbon dioxide.

And prior to the 1980's climate change meant global cooling.

Answer 2

Here is a little briefing from someone who happens to really know about this. One very important fact that people fail to realize is that the "ozone hole" is actually over the South Pole not the Nort Pole. So the idea that banning flurocarbons in the U.S. would have any effect was B.S. from the beginning. They still use flurocarbons in Mexico and South America as well as many other countries in the world.

What creates ozone? The sun shinning on the atmosphere. Where does the sun shine on the atmosphere the most? The equator. Were does it shine the least? SOUTH POLE!!! Make a connection yet?

Ok how about this? Flurocarbon molecules are heavier than air. They fall on the ground, they don't fly up to the stratosphere. Make any connection?

What about ozone near the ground? In the summer, when far more people are using airconditioners and therefore flurocarbons you will often have ozone alert days. What is an ozone alert day? Those are days when there is TOO MUCH OZONE!!! See a connection?

What if air currents are carrying flurocarbons up into the stratosphere? Ok, what is the main weather pattern on earth? The sun heats up the earth at the equator. The earth and sea heat up the air at the equator which rises up to the stratosphere. Wait a minute!!! I thought the ozone levels were highest at the equator!!! They are . See a connection?

There is only one possible conclusion to draw from all of the misinformation that has been distributed far and wide by so called "scientists" about the ozone hole. The idea that man is causing it is simply not true or in other words a lie. It did not stop congress from passing legislation did it? Same with global cooling and now with global warming.

Answer 3

Ozone depletion is a natural phenomenon. The sun makes ozone (ultraviolet light). Ozone is a very unstable gas. It is quick to react and combine to other gasses to become more stable. If it did not do this all the oxygen would eventually become ozone and we would all die. Lucky for us it goes back to , eventually, oxygen. The more ozone buffer we have up there the less uv penetrates and the less ozone is made. When the ozone depletes the sun penetrates more and crates ozone at a faster rate. Isn't it neat how it works? No mater what happens it always corrects its self. It opens and closes on a regular basis and has been doing that ever since we found out it was there. We don't know about any thing before that but would have to assume that it was no different than now. The sun's activity will cause an increase or decrease in its production because of solar cycles. Its depletion increases and decreases with volcanic activity. (lots of that south of the equator) But that isn't all that exciting so we have to make up causes for political purposes.

Answer 4

The ban was phased in, and did not take effect for many years. It still hasn't come into full effect. And CFCs last a long time.

The ozone hole was steadily growing larger for a while. As the ban took effect, it started to increase less rapidly.

Recently, it has stopped growing significantly and pretty much all scientists expect to see it start to recover.

Answer 5

I have heard that CFCs are not banned world wide, only in major industrial countries. They continue to be used in third world countries. Also, I have heard the ozone hole is closing, so it isn't bigger now. I have not verified those facts, but they sound plausible.
