Well, I'm happy to report that it appears the Ozone is no longer disappearing and may return to full strength by 2048. From Daily Mail:
The ozone layer is no longer disappearing and could be back to full strength by the middle of this century, UN scientists have confirmed...
The phasing out of nearly 100 substances once used in products like refrigerators and aerosols has stopped the ozone layer being depleted further, although it is not yet increasing, according to a new United Nations report released last week...
The ozone layer outside the polar regions is projected to recover to pre-1980 levels by 2048, although the annual springtime ozone hole over the Antarctic is not expected to recover until 2073.The plot at the top of the post is what the Ozone looks like today and the image below shows what it looked like before 1980. As you can see there is still a noticeable difference but all indications are that this issue will go away.
I can find two take away messages that you are free to debate:
- The scare tactics may have been over done. (At least at my school.)
- The world coming together to work on problems together can actually accomplish a lot of good.
