The east of the country, including Tasmania, Longer fire seasons will reduce opportunitiesįor controlled burning and increase pressure on firefighting resources. That the frequency of long fire weather seasons has increased in easternĪustralia. Analysis of global climate data has shown
No stations showing decreases stations showing significant increases in FFDIĬlimate change is also having an impact on the length of theĪustralian fire season which now extends beyond summer, into October and March, Period 1973 to 2010 at 16 out of 38 measuring stations around Australia, with (FFDI), an indicator of fire danger weather, increased significantly over the Tasmania and other parts of southeast Australia. Over the last 30 years extreme fire weather has increased in Many extreme weather events, including extreme bushfire conditions. Will result in longer fire seasons and an even larger number of days of extremeĬlimate change is increasing the frequency and severity of Increased incidence of drought – coupled with consecutive hot and dry days – In Australia’s southeast, it is very likely that an Normally account for much of the cool-season rainfall in southern Australia. The southward shift of the rain bearing fronts from the Southern Ocean, which Climate change is likelyĪ contributing factor to the observed rainfall declines via its influence on Other parts of southeast Australia from the mid-1990s. The reduction is most pronounced in Tasmania and Past few decades, characterised by a 10-20 percent reduction in cool-season Southern Australia has experienced a drying trend over the Climate change,ĭrying trend in southeast Australia and more high fire danger weather Trend likely influenced by climate change. Rainfall was below average for Tasmania, indicative of a two-decade drying Of sites were near record-high for so early in the season. The early October heatwave Forest Fire Danger Index (FFDI) values at a number Extreme fire danger was declared over much of Tasmania during To October created conditions conducive to dangerous spring fire weather across Temperatures for December observed over large parts of Tasmania.īelow average winter–spring rainfall and a very warm start Exceptionally high minimum temperatures on the night ofġ9–20 December were even more significant, with record-high minimum Numerous December records were broken in Tasmania for daily October–December was also the warmest on record for both maximum and minimum November mean temperatures were the equal second-warmest on recordĪnd spring as a whole was the second-warmest on record for Australia.

You can download the briefing paper here, or read on below: What’s happening in Our briefing paper, issued today in response to many media and public enquiries about the effect of climate change on the fires, found that a long-term drying trend, record-breaking dry spring and a dry, hot summer – driven in large part by climate change – played a significant role in increasing the susceptibility of the forests to fire. Experts say much of the burnt areas of alpine flora is unlikely to ever fully recover. More than 72,000 hectares of western Tasmania have been burned by a cluster of bushfires ignited by lightning strikes on January 13. A range of climate change factors combined to create the tinderbox conditions that led to devastating fires destroying ancient forests in Tasmania, our new briefing paper has found.
