Did scientific knowledge and explanations about the ozone layer change over time?

Answer 1

Yes. First we didn't know we had an ozone layer, and we didn't know that the Sun made very energetic radiation that it radiated towards us in quantities sufficient to kill us and sterilize the Earth's surface. Next we discovered the ozone layer, and spotted energetic radiation (UV-B) arriving at Earth's surface from distant stars through the newly discovered ozone hole that were not too much hotter than than our own Sun. Whoa, this means the ozone layer is protecting us! Then we spotted chemicals in the ozone hole, some of which were in the middle of an ozone "meal", and assumed the hole was made by them. A little more than 80% of those chemicals are only made by Man. Still we look at the "problem" with a choice of personal blinders, whether we want to believe we are "guilty of all harm", or that we are "too small to matter", and we get confused by the distractions raised by either of those two camps. Regardless of the cause, more UV-B is arriving on the "heads" of more people with each passing year. Note in the attached link, that very few people live near the equator, where "UV-B intensity is relatively unchanged". And we'll have yet more to discover in the future...

Answer 2

Yes, scientific knowledge and explanations about the ozone layer have evolved over time. Initially, there was uncertainty about the causes of ozone depletion, but with research and evidence, it became clear that human-made chemicals, such as chlorofluorocarbons (CFCs), were the primary culprits. This understanding led to the implementation of international agreements like the Montreal Protocol to phase out these harmful substances and protect the ozone layer.

Answer 3

yes it does. The ozone layer changes from winters to summers.
