Australian bushfire season 27 days longer than 40 years ago: report


CANBERRA, July 1 (Xinhua) — The number of days of extreme firefighting in Australia has increased significantly over the past 40 years, a study finds.

According to a report published Friday by the Commonwealth Scientific and Industrial Research Organization (CSIRO), the number of days of extreme wildfires per year increased by 27 or 56 percent between 1979 and 2019.

In comparison, the number of days with extreme firefighting increased worldwide by 54 percent during the same period.

Pep Canadell, CSIRO researcher and author of the study, said the increase in the number of days of extreme weather translated into a higher number of wildfires, as seen during the Black Summer 2019/20 when fires raged in every state and every state. area.

“Australia has always experienced extreme bushfires, but the black summer of 2019/2020 highlighted an increasing trend in fire activity,” Canadell said in a statement.

“These new findings show that all of Australia has seen an increase in extreme fire events and extreme fire days over the past four decades.”

According to future climate scenarios included in the report, an increase in global temperatures of 1.5 to 4 degrees Celsius by 2100 could extend the fire season by an additional 11 to 36 days.

“Australia’s highly variable firefighting conditions contribute to annual variability in fire activity, but we are seeing a marked increase in fire season and firefighting trend over time. Long-term climate change is driving increasing trends,” said canadall.

“Our research demonstrates the importance of understanding how trends in firefighting can help responders, policy makers and the community better prepare for and respond to wildfires. It also highlights the importance of reducing global carbon emissions.”
