The ozone layer plays an important role in protecting us from harmful ultraviolet radiation from the sun. So what happens when it’s put at risk? 

This past Thursday was the 34th annual Ozone Protection day. Dating back to 1987, the Montreal Protocol is the global agreement to protect the ozone layer. The agreement is the first treaty to be agreed upon by all 198 UN state members, including Australia. The goal is a global push to eliminate ozone-depleting substances and allow the ozone layer to heal. This year’s event had an emphasis on the Montreal Protocol but also slowing the effects of climate change.

In celebration of Ozone Protection day, UNSW professor and climate scientist Steven Sherwood joins Jarred Cross to talk about the importance of protecting our ozone layer, as well as what’s being done about the current global warming crisis.
