Australia's arid climate and oil-rich eucalyptus forests mean that forest fires are one of the inevitable sights in the country. There have been several large-scale forest fires recorded in Australian history, such as Ash Wednesday in 1983, which killed 75 people, and Black Friday in 1939, which killed 7 1 person.

However, the forest fire in Victoria is the deadliest forest fire in the country, and experts believe that this problem is related to climate change.

Morgan, director of the Australian Forest Fire Cooperative Research Center, said: "Climate change and dry weather have changed the nature, fire and burning time of forest fires ... This weekend's forest fires highlighted the importance of scientific research to promote our understanding of the various effects of forest fires."

McKellar, an Australian poet, described Australia as "a dry land and a flooded plain", and Adams, a forest fire expert at the University of Sydney, also said that there is evidence that Australia's climate is becoming increasingly unstable.

Australia has a large forest area, and there are some fires every summer.

Melbourne fire, according to the police, was first because the fire was very serious. Victoria has been under high temperature control for the last week, and the high temperature of 43 degrees Celsius lasted for a week, setting a historical record since 1908. When the forest fire started raging on February 7, the temperature in Melbourne, the capital of the state, had risen to 46.4 degrees Celsius. Long-term high temperature and drought make forest fires spread more easily. The wind speed as high as115km and some arson incidents also accelerate the spread of the fire, which makes many people be swallowed up by flames before they can escape from their homes. Victorian Governor brumby said that the fire was as terrible as a war. Because the fire was so fierce, the firemen could do almost nothing.
