By Annette Ekin We’re fighting a different kind of wildfire whose behaviour experts are struggling to predict. Climate change and negligent forest management are causing higher-intensity, faster-moving fires that can generate enough energy to evolve into erratic firestorms, known as pyroCbs, in the face of which first responders can do little. ‘Traditionally we could predict the fire behaviour and the … Read more
