What's going on with the ozone?
It's time to chat about something that fascinates kiwis young and old - it's the ozone layer. Turns out there's a giant ozone hole above the Antarctic right now. This month it peaked to a cool 27 million square kilometers, the biggest in 20 years. So, is this as alarming as it sounds and what is going on with our efforts to protect it? Joining Emile for a chat is Postdoctoral Fellow in Physics at the University of Otago, Hannah Kessenich, who's been writing about this for The Conversation.
