Wildfires raged in southeast Australia in September 2019
They claimed the lives of 33 people. About 11 million hectares of forest burned down.
Estimates of dead animals vary from 400 million to 1.25 billion individuals!!! (including koalas), and these are only mammals, birds and reptiles.
These fires were among the worst in history and the main causes of the fire were record heat and drought, frequent lightning strikes during thunderstorms in the region, unintentional and deliberate arson.
Forest fires shape their weather in a disaster area, smoke rising into the sky can form a new lightning strike in an arid zone
