This season, the bushfires
in Australia have burned more than 12.35 million acres of land. At least 25
people have been killed and 2000 homes destroyed. According to the BBC, this is the most casualties (伤亡) from wildfires in the
country since 2009. The University of Sydney estimates that 480 million animals
have died in South Wales alone.
Zeke Hausfather, an energy
systems analyst and climate researcher at Berkeley Earth, said warmer
temperatures and extreme weather have made Australia more susceptible to
fires and increased the length of the fire season. "The drier conditions
combined with record high temperatures in 2019 created main conditions for the
disastrous fires. Australia's fires were worsened by the combination of those
two. 2019 was the perfect storm for being the warmest year on record for
Australia and the driest year on record for Australia," Hausfather added
on Friday.
Kevin Trenberth, a senior
scientist at the US National Center for Atmospheric Research, said warmer ocean
temperatures also contributed to more variable weather around the world.
Trenberth believes that global warming contributed to energy imbalances and hot
spots in the oceans, which can create a wave in the atmosphere that locks
weather patterns in places, causing longer rain events in Indonesia, for
example, and at the same time contributing to drought in Australia. He said
that once an area experiences drought conditions for two months or more, it
increases the risk of fires catching and spreading. Those changing weather
patterns due to global warming make drought events longer.
Climate experts stress that
climate change is not the only factor in the severity of wildfires. How land is
managed can also impact the amount of fuel available for fires. Practices like
controlled burns and other factors can impact the risk to people and property,
such as warning systems and the type of development in a given area. Changing
those policies has great potential to limit future damage from wildfires along
with changes to how fire management resources are dispatched (派遣).
