The Future of Oz: Wildfires, heat waves, and climate change


During the 18 years I spent growing up in Perth, Western Australia, I never experienced Christmas with a “real” Christmas tree. We used a plastic tree (as did many other families) for fear that our house would catch on fire in the intense summer heat.

That fear has become a reality for many in recent months after Australia’s latest wildfires – the worst in the nation’s history - killed over 180 people. Almost 500,000 acres and over 700 homes were destroyed by the fires that spread throughout Victoria, a state in south-eastern Australia.

Just a week ago I was reading about the worst heat wave on record in this very same state. Temperatures soared up to 115 degrees Fahrenheit – the hottest on record. Unprecedented droughts in the region combined with extreme heat created the perfect fuel for this blistering inferno. Experts are saying that this is only the beginning of the effects of climate change that Australia will face in coming years.

Fires have been a part of the Australian landscape for millions of years. The natural ecosystems have evolved; the plants have adapted. But, add people to this vast and relatively empty continent and fire becomes a terrifying prospect.

All it takes is a single spark from a cigarette or a lightning strike, and the grasses will light up, the dried bush will catch on fire, and then the wind comes…. Before too long, you have a glowing river of flames expanding across the landscape. You would have to search very hard to find an Australian who is not afraid of wildfires. We all know someone who has been affected.

These recent fires are the worst in Australia’s history since the Ash Wednesday fires of 1983 and the Black Friday fires of 1939 that devastated south-east Australia. This region is considered to be one of the most fire-prone areas in the world, along with southern California. Both regions are predicted to be at greater risk of wildfires as a result of climate change.

According to a World Bank Report (see here), Australia increased its carbon dioxide emissions by 38% between 1994 and 2004 making it the sixth highest per capita emitter in the world -- mostly as a result of their dependence on coal-fired power. So, what is Australia's response to climate change? Their current target is only a pitiful 5% reduction by 2020. This is not enough if we want to avoid a repeat of these fires (see this link for recommended actions).

Luckily this most recent fire did not reach the state’s most populated areas, but what about next time? My own hope is that we can find better solutions to wildfire management in Australia before we need to resort to living in fire proof homes below the scorched surface.

If you want to encourage Australian politicians to take action on climate change, check out TheBigSwitch.org.au. This organization is working to encourage Australians to talk to their local politicians to take action.

Teagan,
A very timely post. I like your writing style and laughed at your last line "living in fire proof homes below the scorched surface." Lots of good links!

Recommendations:
1) Your side note is a great personal anecdote. I would make it into the first paragraph and then connect it to the wildfire story in Victoria.

2) You mentioned Australia needs to work on fire management. Could you mention what Australia is doing to work on climate change, since this is one of the main drivers?
