Montreal Protocol and the Ozone Hole

Having once worked in the Antarctic, my ears always perk up anytime I hear anything about the ozone hole. I remember how vibrant and beautiful the nacreous clouds were that came out in the Austral spring but were also a sign of depleting ozone.

So I was please to read this BBC article titled, “How Arctic ozone hole was avoided by Montreal Protocol.” The article states that the Antarctic ozone hole would have been 40% bigger by now if ozone-depleting chemicals had not been banned in the 1980s in accordance with the Montreal Protocol, and that the Arctic hole would have been large enough to affect all of northern Europe, including the UK. It is a great example of how an international environmental treaty can have a real impact on a problem.
