Weather experts say the world is starting to see new types of wildfire – including enormous Pyrocumulonimbus fire clouds that spit lightning and black hail.
These infernos can burn for more than a year. They can also spawn fire tornadoes, which move at more than 200 kilometres an hour destroying everything in their path.
Climate Question hosts Graihagh Jackson and Jordan Dunbar talk to John Vaillant, the author of “Fire Weather”, about how wildfires are increasing in intensity and frequency, and how they are burning in places they have never burned before.
