For the past month fires have ravaged through parts of
Tasmania’s World Heritage listed forests, destroying 1,000 year old
trees. Is this the new normal?
Over
100,000 hectares have been damaged by bushfires, including parts of the
World Heritage Area containing trees that are over 1,000 years old.
As a 20 year old student I remember hiking through the world-heritage listed Walls of Jerusalem.
With its panoramic views and horizon of jagged peaks, this national
park is a treasure for outdoor enthusiasts who come to experience
Tasmania’s vast and unique landscape. It was there that I first saw
peat, the spongy water-logged soil that supports the ancient pencil
pines high up in the cold air. My friends and I camped by tannin-stained
lakes, daring each other to swim in the icy waters, and subsequently
froze through the nights with wet hair. In Australia during the summer
when most of the country is sweltering hot, I couldn’t believe there was
a place that was so cold and wet.But parts of this scenic, protected area are now charred. Photos by Rob Blakers and Dan Broun show the extent of the damage. Incinerated tree trunks, skeletal-like tree branches and scorched earth as far as the eye can see.
This area used to be alive with vegetation, but fires have left it scarred.
Since January 13 fires have ravaged areas of Tasmania, Australia’s island state. Caused
by dry lightning strikes, the fires have destroyed tracts of ancient
World Heritage-listed forests. Some of the trees are over a thousand
years old and can trace their roots back to Gondwanaland, the huge super-continent.
This is an area that is not used to burning of this
scale. High up on the wet central plateau plants, animals, and native
bushland are not evolved to cope with fire like this. It is the home to
ancient alpine species like pencil pines and cushion plants. It takes
hundreds, if not thousands of years for this ecosystem to properly
regenerate after a fire and some experts are sceptical if it ever will. Once lost, parts of this unique landscape are gone forever.
This part of the forest has been safe so far, but smoke shows the fires are nearby.
So why is this happening?
In 2015, Tasmania experienced its driest spring on record, then
December saw record-breaking high temperatures. The area was tinder dry
enough to burn, when it was hit by an extraordinary series of dry
lightning strikes - lightning without the rain. Tasmanian Premier Will Hodgman is reported as saying:"We received advice of 1000 strikes on one day. The highest recorded in previous years was more like 19.”
Quickly, experts have drawn links to climate change.
"This is what climate change looks like," said David Bowman, Professor of Environmental Change Biology at the University of Tasmania.
“We are watching centuries-old ancient forests being destroyed because we failed to act early enough on climate change," said Professor Will Steffen, climate scientist and Climate Council councillor.
A track surrounded by scorched landscape.So is this the new normal?
There has been an observed increase in the Forest Fire Danger Index (FFDI) across Australia characterised by an extension of the fire seasons into spring and autumn, according to a report released late last year by Australia’s national science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), and the climate and weather agency, the Bureau of Meteorology (BOM). According to the report, “the FFDI increases are partly driven by temperature increases that are attributable to climate change.”
But it’s not just Australia where this is happening.
Predictions from scientists globally are that these sorts of extreme
weather events will happen more and more.
A scientific study in Nature Communications has shown that the frequency of long fire weather seasons has increased. And in the US, President Obama's science adviser John Holdren has said that, "climate change has been making the fire season in the United States longer and on average more intense."“This is what climate change looks like.”
With devastating fires happening across the globe it’s a warning that we must urgently take action to stop catastrophic climate change. This starts with keeping fossil fuels in the ground and creating a 100% renewable future, as well as protecting the world’s remaining forests. Governments like Australia’s must become climate leaders, and ramp up their ambition by cutting emissions deep and fast, ratifying the Paris agreement, and investing in renewables. Unless we stabilise the climate, extraordinary places like the Walls of Jerusalem will remain at risk.
