From California to Australia, Wales to Bodmin Moor, news of wildfires has increasingly flickered across our screens. Not only do these fires dramatically change our landscapes, they also release huge amounts of carbon dioxide into our atmosphere. But what constitutes a wildfire? And how does it affect wildlife and humans? Thomas Smith from the London School of Economics and Political Sciences visits Exeter to share his experience of chasing wildfires across four continents. Thomas is an environmental geographer who specialises in pyrogeography – the study of fire on earth. Together, we'll explore the science of wildfires, what they can tell us about the drivers, the impacts of environmental change, and the implications to our lives and broader society. Everyone is welcome! Come along, make comments, and ask questions!
