The number of severe bushfire danger days has increased in spring for large parts of Australia

This map shows the increase in severe fire weather days in spring for the period 2000 -16 compared with 1983-99. In some areas there are an extra 10 high bushfire danger days in the season than there used to be. A severe fire weather day is defined here as when the forest fire danger index (FFDI) is high (>90th percentile)

Severe bushfire danger days are projected to increase in the future if global carbon emissions remain high

This map shows the projected increase in days rated high fire danger or above (FFDI > 25) for the period 2060–79 when compared with 1990–2009. The model uses a high emissions scenario (RCP 8.5) and uses the GCM-based ensemble data
