Ozone production is tied to solar activity disproportionately, and the 11 year cycle between the solar maximum and the solar minimum effect ozone measurements. We are currently at solar minimum, and we are also possibly headed into a grand solar minimum (an extended period of low solar activity).
Zaelke also does not seem to have published a paper on his findings, and all of his quotes in this article are largely political-oriented fluff. The latest thing I can find with anything that has his name on it is from 2009, and only discusses the Montreal Protocol in relation to lowering CO2 emissions.
So, the article just tells us CFC-11 detectors detected something (which may or may not be CFC-11), but cannot tell us how much, where, or how it effected climate activity during a time of natural low ozone production.
Also, this does not discuss if this was production, or just older appliances breaking down or being taken apart for recycling improperly. Without a paper, we cannot tell how they accounted for this.
