:: alarmed by a growing “ozone hole” ::
Thank you, Mr. Editor for using quotes here.
Years before the Montreal Protocol, it was discovered that the sensitive ozone layer ^over the Antarctic^ was not complete and the area free of O3 appeared to be growing. Later, it appeared to be closing (yet never quite closing altogether. Then, OMG, it’s growing again!)
Scientists diligently determined that certain CFRs consumed ozone and therefor MUST be contributing to the “hole”.
What was never explained was 1) was the “hole” closed at anytime BEFORE it was discovered? 2) why is the “hole” only over the Antarctic? and, 3) what is the dynamic that causes the “hole”?
In my opinion, “science ngo-s” assumed a problem then assumed it was anthropogenic and went out and found a conclusion to match their hypothesis. Voila! No more efficient refrigerants for you!
Yep. Global temps down a RECORD 0.56 (or was it 0.59?) degrees Celcius - a a stunning drop - over the past two years, so we have to go back to the last thing that “worked”, an OZONE HOLE! Gasp. Double Gasp.
