Fear & Wonder is a new climate podcast, brought to you by The Conversation. It takes you inside the United Nations’ era-defining climate report via the hearts and minds of the scientists who wrote it. The show is sponsored by the Climate Council, an independent, evidence-based organisation working on climate science, impacts and solutions.

The show is hosted by Joelle Gergis, a climate scientist and lead author for the UN’s Intergovernmental Panel on Climate Change (IPCC), and her friend Michael Green, an award-winning journalist.

In this episode, we're unraveling one of the major shifts in the public communication of climate change – the attribution of extreme weather events to climate change. In the past, we knew climate change made extreme weather more likely, but couldn't say for sure if an individual weather event might've happened in a cooler world too. But scientists have now developed more sophisticated models to help determine how connected or influenced the shift in climate is on individual weather extremes.

We speak to climatologist Fredi Otto about a rapid attribution study of a heatwave in Toulouse, France. Then scientists David Karoly and Tannecia Stephenson help us understand how climate models are built and what they can tell us about our changing weather.
