How are these incompatible stories? Worldwide ozone destroying chemical production is way down, which is allowing the ozone layer to regenerate back to pre-industrial levels. Meanwhile, some polluters are cranking out banned CFCs and freeriding on the worldwide reduction efforts.
Much like CO2 production, some level of emissions are well within the ability of the biosphere to deal with without harm. But if everyone emits willy nilly then we'll end up well past those limits.
- throwaway5752 8y agoHow much CFC production was accounted for in the models that predicted the O3 layer healing? How much production can be handled and what is current production? Those are the answers one would have to have before writing this off.

I thought ozone layer density (is that the right term?) was directly measurable? https://science.howstuffworks.com/environmental/green-science/ozone-layer2.htm https://science.howstuffworks.com/environmental/green-scienc...
- kaybe 8y agoYes, and it is not even that hard. But we cannot measure the future, thus we use models to predict, and those need inputs (such as emitted CFCs) which can be wrong.
- TheSpiceIsLife 8y agoAh, right, yes, that makes sense now. Thanks.
