‘Dead
things everywhere’: is
Australia facing the summer
from hell?
The
outlook is grim, with low water storage levels and extreme
temperatures forecast
6 September, 2019
Out
in the Macquarie Marshes, about 1ookm north of Warren in the central
west of New South Wales, large inland wetlands have become a place
for the dead and dying.
“We
went out last night and there was a little patch of water with dead
and dying European carp,” Richard Kingsford, the director of the
Centre for Ecosystem Science at the University of NSW, says. “There’s
dead and dying things everywhere. Kangaroos dying and even foxes are
dying.
“We
were trying to trap for turtles but there doesn’t seem to be enough
water for turtles. I’m not sure where they’ve gone to.”
There
are large parts of the Macquarie River that have dried up completely
as the state remains in the grip of one of the most severe droughts
on record.
Valley
water storages in the Macquarie are sitting at 11%. In the Namoi, in
north-west NSW where water shortages have been acute, they’re at
1.5%. The Border Rivers, in the region between the NSW and Queensland
border, are at 6%. In Sydney, dam storages have dropped below 50% for
the first time in more than a decade.
It’s
one part of the climate crisis playing out across much of the
country. A different year, similar story. Most places are drier than
usual, warmer than usual.
Repeat
episode?
The
summer of 2018 brought record-breaking heat for Australia. It’s too
early to say whether this summer will bring such extremes.
But
early outlooks for spring and December are again pointing to above
average temperatures. And with the exception of parts of Western
Australia and the west of Tasmania, the outlook is for below average
rainfall.
“For
most of Australia it’s this consistent dry story for the remainder
of the year,” Jonathan Pollock, a climatologist at the Bureau of
Meteorology, says. “It’s very likely it’s going to be hotter
than usual and it’s very likely it’s going to be drier than
usual.”
For
the first eight months of the year, the country’s mean temperature
was the second warmest on record. Mean maximums were the warmest on
record over the same period and mean minimums the equal-sixth
warmest.
Rainfall
through winter was below to very much below average for most of the
country, including New South Wales, southern and western Queensland,
parts of northern and eastern Victoria, the east coast of Tasmania,
the majority of South Australia and the Northern Territory, and most
of the eastern half of Western Australia, and some coastal areas in
the west of that state.
In
drought-hit parts of eastern and southern Australia, rainfall levels
for the season were in the lowest 10% of historical records.
Pollock
says it would take something like a La Niña, which is associated
with heavier rainfall, “to bring the turnaround that we need”.
The
El Niño-Southern Oscillation is currently neutral and is expected to
remain so until the end of 2019 and into early 2020.
The
prolonged dry and warm conditions have meant authorities have already
issued warnings for the spring and into summer.
Fire
services have told communities to be ready for a challenging bushfire
season and to prepare their homes, properties and evacuation plans
early.
In
drought-hit parts of eastern and southern Australia, rainfall levels
for the season were in the lowest 10% of historical records.
The
Bushfire and Natural Hazards Cooperative Research Centre published
its seasonal outlook last week, which warned parts of Queensland, New
South Wales, Victoria, Tasmania, and parts of Western Australia and
South Australia, face an above normal potential fire threat.
On
Friday, just a week into September, authorities issued total fire
bans in Queensland and parts of New South Wales, with extreme, and
potentially catastrophic, conditions expected in some areas.
Richard
Thornton, the chief executive of the Bushfire and Natural Hazards
Cooperative Research Centre, said winter had brought some significant
fires to the north of the country and recent weeks had seen a spate
of fires in south-east Queensland and NSW.
He
said the ongoing drought was driving much of the risk this season and
there was concern for forested areas that were already dry heading
into the warmer months.
Thornton
said that included a swathe beginning south of Rockhampton in
Queensland and running all the way down the east coast into NSW and
east Gippsland in Victoria.
“That
takes in the major populated areas in south-east Queensland and
around Sydney and the ACT – so some pretty significant population
centres,” he said.
He
said the conditions in eastern Tasmania, South Australia’s Eyre
Peninsula and Kangaroo Island, south-western WA and parts of the
Nullarbor, where rainfall has regenerated grasslands, also looked
challenging.
In
a couple of months, authorities will revisit the outlook to see if
anything has changed heading into January and February 2020.
Along
river systems in New South Wales, the outlook is similarly grim.
In
the summer of 2018, low river flows caused by a combination of
drought and over-extraction of water, coupled with extreme
temperatures, caused an environmental catastrophe that killed
thousands of fish.
Fisheries
managers say they anticipate more fish are likely to perish this
season if the drought continues.
A
spokeswoman for the NSW Department of Primary Industries said it was
“an evolving situation” and aquatic habitats were being closely
monitored.
“Significant
concerns are held for the Lower Darling, Namoi, Macquarie and Lachlan
catchments in the early part of the summer as well as the
Barwon-Darling, Border Rivers and Gwydir should current conditions
persist,” she said.
Up
in Queensland, Angus Emmott, an ecologist and farmer, runs a cattle
station about 130km south-east of Longreach.

The
property primarily receives its rain in summer but, until last year,
it had what he calls “eight failed summer rains in a row”.
That
broke last summer, as a result of “two big floods”.
“We’re
having a really good season unlike much of the country to the east of
us,” Emmott says. “Up above us, near Julia Creek, they’ve had
so much rain it killed three-quarters of a million head of cattle and
washed all the fences and pastures away when Townsville got flooded
as well”.
Emmott
says for his farm it was a case of “luck”. The rains that had
helped his property last year had caused catastrophe further north.
And outside of the floodplains, places were still in drought.
“One
thing that’s really affected agriculture in this part of the
country is climate change,” he says. “That brings hotter than
normal temperatures, drier than usual weather and higher minimums.
“Then
what is happening is when we get a rainfall event there’s more of a
chance of them being massive, like the one at Julia Creek, which
created havoc.”
Emmott
is on the board of the advocacy group Farmers for Climate Action. In
a bit more than a week, he says farmers will be travelling to
Canberra to call for a national strategy on climate and agriculture.
“I
think things can change and they actually are but they would change
so much quicker if we had a government that took some leadership,”
he says. “If we didn’t have to drag them kicking and screaming,
we’d get places a lot quicker. This applies to both sides of
politics. They talk the talk and then do nothing.”
