This week, we investigate how museums use different forms of communication to educate and mobilize the public around the twin existential crises of climate change and global environmental degradation with Miranda Massie, founder of the unique Climate Museum in New York City, and environmental activist Beka Economopoulos, executive director of the US based Natural History Museum. Both guests were in Australia as keynote speakers at the ART+CLIMATE=CHANGE 2019 festival.
