Future wildfire warning for Australia on 50th anniversary of Tasmania’s Black Tuesday

Increasingly dangerous fire weather is forecast for Australia and the Mediterranean as the global footprint of extreme fires expands, according to the latest research.

University of Tasmania Professor of Environmental Change Biology David Bowman led an international collaboration - including researchers from the University of Idaho and South Dakota State University - to compile a global satellite database of the intensity of 23 million landscape fires used to identify 478 of the most extreme wildfire events.

“Extreme fire events are a global and natural phenomenon, particularly in forested areas that have pronounced dry seasons,” Professor Bowman said.

“With the exception of land clearance, the research found that extremely intense fires are associated with anomalous weather – such as droughts, winds, or in desert regions, following particularly wet seasons.

“Of the top 478 events, we identified 144 economically and socially disastrous extreme fire events that were concentrated in regions where humans have built into flammable forested landscapes, such as areas surrounding cities in southern Australia and western North America.”

Using climate change model projections to investigate the likely consequences of climate change, the research found more extreme fires are predicted in the future for Australia’s east coast, including Brisbane, and the whole of the Mediterranean region – Portugal, Spain, France, Greece and Turkey.

“The projections suggest an increase in the days conducive to extreme wildfire events by 20 to 50 per cent in these disaster-prone landscapes, with sharper increases in the subtropical Southern Hemisphere, and the European Mediterranean Basin,” Professor Bowman said.

The research has been published today in the prestigious scientific journal Nature Ecology and Evolution.

The research is released on the day the State remembers the impact of the 1967 bushfires in the city of Hobart and across the South, which claimed the lives of 62 people, left 900 injured and more than 7,000 homeless.
