Renowned atmospheric scientist Professor Darryn Waugh (UNSW and Johns Hopkins University) delivered a public lecture, The enduring impact of the ozone hole on climate, to a packed audience at UNSW Sydney on Monday 30 July.
The event marked the official launch of the Mathematics for Planet Earth (M4PE) Initiative, which promotes mathematical research that benefits society and the environment. Dr Shane Keating, co-director of M4PE, opened the lecture in the Scientia’s Tyree Room, welcoming the 100 attendees and introducing Professor Waugh.
During his lecture, Prof Waugh spoke about the history of the ozone debate, and the good news story of the Montreal Protocol. The Protocol, ratified three decades ago, was the first concerted international effort to impose short-term economic cost to protect against a “speculative” global environmental problem.
However, he warned that vigilance was still needed due to the slow recovery of the ozone, and potential non-compliance of countries to the Montreal regulations, as recently seen in China where widespread use of CFC-11 in the construction industry has been detected.
The lecture was held on the same day that an article on the ozone hole by Dr Keating and Prof Waugh appeared in The Conversation.
