The unusual nature of Australia s Black Summer bushfires may have marked the beginning of a new fire-fuelled ice age and the world seems to have crossed a threshold to a more dangerous future, a global fire historian says. Emeritus Professor Stephen Pyne at Arizona State University is a former firefighter in the US who has previously studied Australia s fires for his 1991 book

Prof Pyne said the 2019/2020 blazes, which ripped through 24 to 40 million hectares of bushland across multiple states and territories, marked the start of a global year of fires.
