Rnz: Our Changing World

Smoke explosions. Fire tornadoes. Burning couches. It all happens in the fire lab: a purpose-built facility where researchers can safely set stuff on fire and study how it burns, for science. New Zealand experiences 4,500 wildfires every year, with the risk ramping up due to climate change. We visit the fire lab to watch a large gorse bush go up in flames and learn how this helps us prepare for future wildfires.
