Ozone Layer over Antarctica

The Montreal Protocol, which came into force in 1987, is a global agreement to protect the Ozone Layer.  How well is it working, now in 2019?  This question was put to scientists at the British Antarctic Survey . at the Halley research station on the Brunt Ice Shelf.  Although this ice shelf itself is close to splitting,  Halley is not in danger from this event.

The simple answer is that the Ozone Layer is in a much healthier state than it was in the late 1980's.  This is really good news since the Ozone Layer filters out the harmful ultraviolet radiation from the sun.  We are warned that we can't be complacent , or think that our work is done.  Scientists world-wide continue to be vigilant, in this and many other areas.
