Understanding Climate Change and the Montreal Protocol

The video discusses the challenges of climate change communication and trust, using the Montreal Protocol as a case study. It highlights the success of the protocol in addressing ozone depletion and draws parallels to current climate change issues. Key lessons include acting despite uncertainty, the importance of collaboration, and incremental progress. The speaker emphasizes the need for collective action to address global warming.
