Climate change impact on bushfire risk in New South Wales, Australia

Australia is one of the most vulnerable countries that influenced by climate change. IPCC proved that the circumstance of climate change has affected the frequency of extreme weather, such as bushfire, and extreme rainfall. Bushfire will not happen without one of the compulsory and necessary risk factors as below: fuel load, low fuel moisture, ignition source and fire weather. Vegetation in Australia is adapted to burn. Fire weather including four switches, lasting high temperature, less precipitation based on extreme hot wave, relative humidity and speedy wind [2]. Both vegetation and fire weather result in the increasingly more severe fire regime across Australia. In this paper, Forest Fire Danger Index (FFDI) will be used for computing for fire danger rating and analysis relationships between climate change and bushfire risk.
