Bushfires in Australia

Australia is being ravaged by the worst wildfires seen in decades, with large swathes of the country devastated since the fire season began late July.

A total of 24 people have died nationwide, and in the state of New South Wales alone, more than 1,300 houses have been destroyed. State and federal authorities are struggling to contain the massive blazes, even with firefighting assistance from other countries, including the United States.
All this has been exacerbated by persistent heat and drought, and many point to climate change as a factor making natural disasters go from bad to worse.
There have been fires in every Australian state, but New South Wales has been hardest hit.
Blazes have torn through bushland, wooded areas, and national parks like the Blue Mountains. Some of Australia’s largest cities have also been affected, including Melbourne and Sydney — where fires have damaged homes in the outer suburbs and thick plumes of smoke have blanketed the urban center. Earlier in December, the smoke was so bad in Sydney that air quality measured 11 times the “hazardous” level.
The fires range in area from small blazes — isolated buildings or part of a neighborhood — to massive infernos that occupy entire hectares of land. Some start and are contained in a matter of days, but the biggest blazes have been burning for months.

What is causing the fires?

Each year there is a fire season during the Australian summer, with hot, dry weather making it easy for blazes to start and spread.
Natural causes are to blame most of the time, like lightning strikes in drought-affected forests. Dry lightning was responsible for starting a number of fires in Victoria’s East Gippsland region in late December, which then traveled more than 20 kilometers (12.4 miles) in just five hours, according to state agency Victoria Emergency.
Humans can also be to blame. In November, the NSW Rural Fire Service arrested a 19-year-old volunteer member on suspicion of arson, charging him with seven counts of deliberately setting fires over a six-week period.

Why are the fires so bad?

Fire season in Australia is always dangerous — the 2009 Black Saturday fires killed 173 people in Victoria, making it the deadliest bushfire disaster on record. But conditions have been unusually severe this year, fanning the flames and making firefighting conditions particularly difficult.

Australia is experiencing one of its worst droughts in decades — the country’s Bureau of Meteorology said in December that last spring was the driest on record. Meanwhile, a heatwave in December broke the record for highest nationwide average temperature, with some places sweltering under temperatures well above 40 degrees Celsius (about 113-120 degrees Fahrenheit).

When will the fires end?

Unfortunately, Australia is only just entering its summer season. Normally, temperatures peak in January and February, meaning the country could be months away from finding relief.
The fires are unlikely to end entirely since they are an annually occurring event — and may even get worse if recent years are a guide.
