Arson. Destructive and highly dangerous, there are very few crimes that make people angrier in a bushfire season. But emotions move faster than fact: how many bushfires really are started by arsonists? And is arson really a more pressing issue than other things that influence bushfires – like climate change?

In the third season of ‘Debunks’, the new podcast series from the Cosmos newsroom team and Nine Podcasts, science journalist Imma Perfetto explores all the science on bushfires. In this episode, she dives into the arson narrative: how we can tell what’s started a bushfire, what arsonists are like, and how concerned we really need to be.

Debunks is a science podcast that asks questions that you actually want answered. Each week a journalist in the Cosmos newsroom expertly guides listeners through the science topics of the day, from EVs and bushfires to Ozempic. Plus we unpack all the misinformation that comes with it.
