Labor To Tell Business It Won't Let Energy Policy Be Held 'Hostage'

Labor will use an energy summit convened by small business to declare it will not “be hostage to repeal politics” if it wins the coming federal election, warning it will press ahead with emissions reduction in the electricity sector even if the Liberal party won’t reconcile itself to the national energy guarantee.
Pat Conroy, the shadow assistant minister for climate and energy, will tell Wednesday’s summit Labor wants bipartisan agreement post-election, and will pursue the national energy guarantee developed by Malcolm Turnbull and Josh Frydenberg – a policy that remains popular with a number of stakeholders, including business groups, despite being dumped by Scott Morrison.
But Conroy will also use Wednesday’s outing to put business on notice, telling them an incoming Labor government will not delay policy action endlessly in a fruitless quest for bipartisanship.
“We will not allow the energy sector to be hostage to the repeal politics we saw at the turn of the decade,” Conroy will tell the summit. “Instead we will progress a 10-year energy investment plan that will deliver certainty to the energy sector through long-term contracts – contracts that will enable massive investment in new generation at the cheapest possible cost.”
Bill Shorten last November outlined Labor’s plan B in the event Labor wins the May election and the Coalition can’t be persuaded, post-election, to back its own policy with a higher emissions reduction target of 45%.

Shorten committed to topping up the Clean Energy Finance Corporation to the tune of $10bn and unveiled a new $5bn fund to modernise ageing transmission infrastructure – the ramparts of a 10-year plan to boost the share of renewable energy in the grid and retire coal generation.
The Labor leader said he would use the Australian Energy Market Operator’s integrated system plan as the basis for transforming the energy system, with a Shorten government playing a hands-on role creating renewable energy zones, investing in new generation and transmission infrastructure and also in firming technologies, like batteries and gas peaking plants.
Moving away from the national energy guarantee, even though Labor has clearly telegraphed that possibility, will likely generate pushback in the business community which rallied in support of the policy which became a casualty of the conservative-led push against Turnbull’s leadership of the Liberal party.
While the Morrison government has been attempting to increase political pressure over Labor’s higher emissions reduction target, warning of the costs associated with a more rapid transition to low emissions technologies, Conroy will insist on Wednesday that Labor’s policies will deliver lower energy prices.
He says there has been an increase in wholesale electricity costs principally because of “the failure of the current government to establish and implement a stable and coherent climate and energy policy”.
“We have had nearly 5,200 megawatts of capacity retire in the last seven years, in fact nearly 4,000 megawatts of capacity has retired since August 2014,” Conroy will say.
“This has led to a tightening of the wholesale energy market as insufficient supply has been added, and this has led to black coal and gas generators increasing their share of time as the marginal generator, thereby setting the price.
“Beyond being more expensive forms of generation, the cost of black coal and gas has risen at the same time leading to higher wholesale prices.”
Conroy says Labor’s commitment to achieving 50% renewable energy and the associated investment in transmission infrastructure to make the renewable energy reliable, “will actually deliver lower power prices than what would otherwise be”.

Indian Summer Monsoon Amplified Global Warming 130,000 Years Ago, Helping End Ice Age

The past may be a surprisingly useful guide for predicting responses to future climate change. This is especially important for places where extreme weather has been the norm for a long time, such as the Indian subcontinent. Being able to reliably predict summer monsoon rainfall is critical to plan for the devastating impact it can have on the 1.7 billion people who live in the region.
The onset of India’s summer monsoon is linked to heat differences between the warmer land and cooler ocean, which causes a shift in prevailing wind direction. Winds blow over the Indian Ocean, picking up moisture, which falls as rain over the subcontinent from June to September.
The monsoon season can bring drought and food shortages or severe flooding, depending on how much rain falls and in what duration. Understanding how the monsoon responded to an abrupt climate transition in the past can therefore help scientists better understand its behaviour in the future.

When we researched this weather system’s ancient past, we found it was highly sensitive to climate warming 130,000 years ago. Our new study published in Nature Geoscience showed that the Indian summer monsoon pulled heat and moisture into the northern hemisphere when Earth was entering a warmer climate around 130,000 years ago. This caused tropical wetlands to expand northwards – habitats that act as sources of methane, a greenhouse gas. This amplified global warming further and helped end the ice age.The rate at which today’s climate is changing is unprecedented in the geological record, but our study shows how sensitive the Indian summer monsoon was during a global transition into warming in the past and may still be.

The monsoon rains of yesteryear
Over the last one million years, the climate fluctuated between a cold glacial – known as an ice age – and a warm interglacial as the Earth’s position relative to the sun wobbled in its orbit. The last transition from an ice age into the warm climate of the present interglacial – known as the Holocene – occurred around 18,000 years ago. This period of Earth’s history is relatively well understood, but how Earth system processes responded to these climate changes deeper in time is still something of a mystery.
A recent expedition to drill deep into the ocean floor of the Bay of Bengal gave an opportunity to reconstruct past Indian monsoon behaviour over hundreds of years before the last ice age.

Our study used these deep sea sediments from the northern Bay of Bengal to capture a direct signal of the Indian summer monsoon from 140,000 to 128,000 years ago, hidden in the fossilised shells of tiny microscopic creatures called foraminifera. These plankton species once lived in the upper ocean water column and captured the environmental conditions of the surrounding seawater in the chemical make up of their shells.
We detected the ocean surface water freshening from river discharge induced by the rains of the Indian summer monsoon from 140,000 to 128,000 years ago – a sign of the strengthening monsoon system. This occurred when the Earth was coming out of a glacial state and into the interglacial which occurred before the one we live in, separated by a single ice age. During this period – which we’ll refer to as the penultimate deglaciation – sea levels rose from six to nine metres worldwide.
Ice-core records show that Antarctica began to warm first during the penultimate deglaciation. Southern Hemisphere warming provided a source of heat and moisture which fuelled the strengthening of the Indian summer monsoon, as seen in our records of surface freshening and river runoff from the northern Bay of Bengal.

During this warming period around 130,000 years ago, the Indian summer monsoon responded to southern hemisphere warming while the northern hemisphere and other monsoon systems, such as the East Asian summer monsoon – which affects modern day China, Japan and the Far East – remained in a glacial state.
The Indian summer monsoon pulled heat and moisture northwards, driving glacial melting in the northern hemisphere and helping tropical wetlands expand their range. These expanding tropical wetlands resulted in more methane release into the atmosphere which caused even more warming, setting changes in motion which ended the global ice age.
The Indian summer monsoon is an incredibly dynamic system. Though confined to the tropics, the system is sensitive to climatic conditions in both hemispheres. Due to its role in contributing to methane emissions, the Indian summer monsoon also has an outsize impact on the global climate. Monsoons should not be viewed in isolation, just as the polar ice sheets shouldn’t. Earth’s internal climate system is intrinsically linked and abrupt changes at one place can have significant consequences over time elsewhere.

Climate Change To Blame For Mass Jindabyne Fish Death: Water Ecologist

Fairfax - Finbar O'Mallon

A trout hatchery in the Snowy Mountains has lost 30,000 fish due to high river temperatures and low rainfall, which a water ecologist has blamed on the effects of climate change.
The NSW Department of Primary Industries, which oversees the Gaden Trout Hatchery outside of Jindabyne, confirmed the loss occurred when the Thredbo River hit temperatures of 28.5 degrees around January 26.

Trout are a northern hemisphere fish and begin to stress and die at 24 to 26 degrees, a department spokeswoman said.
"Fish deaths on this scale at Gaden have not been experienced in the last 20 years," she said.
The department also blamed a lack of rainfall on the loss of the 30,000 fingerlings - baby fish - and 1000 broodstock fish, which are used for breeding.
University of Canberra Associate Professor Ben Kefford said it could be good news for native fish in the rivers who get eaten by the non-native trout.
"It will mean they have far less predation from the trout and competition for that matter," Dr Kefford said.
Dr Kefford said he had also witnessed dead trout in the Wellington River in the Victorian alps in January.
"It certainly doesn't surprise me," he said.
"It will be a consequence of a hot summer which is due to climate change and we've currently got very low flows in most of our rivers."
The low river flows were themselves attributable to a lack of rainfall.
He explained that less water meant it was easier for the heat in the air to warm that body of water up.
"If temperatures get hotter and we have increased periods of dry spells this is probably what's going to happen," he said.
Dr Kefford said trout were more susceptible to heat stress hence why they were placed out in mountain alpine streams.
While native fish had higher heat tolerances Dr Kefford said it wasn't well known what their limit was.
The department said the fingerlings lost in January represented three per cent of the entire department's annual stocking production.
"The fingerlings currently at the Gaden Hatchery are in good health and [the department's] fish stockings have continued across impoundments and streams across the state," the spokeswoman said.
"Gaden Hatchery staff did a fantastic job saving the remaining fingerlings by getting them into cooler water as soon as possible."
This summer was Australia's hottest on record with January beating previous heat records as Australians sweated through multiple heatwaves.

Climate Strike: Greta Thunberg Calls For ‘System Change Not Climate Change’ – Here’s What That Could Look Like

The Conversation -

Greta Thunberg, the 16-year-old Swedish climate activist, is calling for system change.
At a press conference in Brussels, she told the European Commission that in order to fight climate change we need to change our political and economic systems – a message that has been repeated on signs and in chants in the student climate strikes around the world.
The school climate strikes, which she started alone in August 2018, have become a social movement with 1,659 strikes planned for March 15 in 105 countries.
But what is system change? How do entire systems change? When we see “save the planet” initiatives, they often look like individual decisions that don’t cost much, like switching to a bamboo toothbrush or washing containers before you recycle them. By all means, do these things, but don’t confuse them with system change.


Most people don’t know how to change political, economic and social systems. They end up making token gestures instead that may even perpetuate the problem. There’s also the question of how to overcome powerful vested interests that benefit from the current system. But there is research that can help us understand system change.
Neo-institutional theory is one approach to understanding how and why people organise collectively. People create meaning, follow rules and reproduce structures – such as classrooms, businesses, offices and community halls – based on assumptions of what is right and proper. Classrooms look similar, not because each time we set one up we rationally decide how to do so, but because we make assumptions about what a classroom is supposed to look like.
Because we are part of these meaning structures, we reproduce existing norms and beliefs and resist change. System change happens when we don’t take our assumptions for granted, which allows more and more people to question the status quo.

Scanning the horizon
Thunberg is telling us that our current political and economic systems are no longer fit for purpose. She is pointing out that the emperor has no clothes.
Changing a system takes time. My research on the LGBT movement in Ireland documented efforts and achievements over 40 years. Homosexuality went from being a crime, to being celebrated in a progressive movement. While the referendum on marriage equality took one day in 2015, the efforts of many to change the system took decades.
The Three Horizons Framework can help explain the different factors that lead to changing systems. Horizon one is business as usual – the status quo – and the outgoing institution in times of change. Horizon three is the new institution – with newly legitimised structures and beliefs. The space between them is horizon two, which is occupied by people focused on social change – who lead the transition from an old system to the new.

Change can seem sudden, but usually it follows many years of changing beliefs. Sheila Cannon, Author provided

Most people recognise the problems with the present system and want to help society move to something more sustainable. Products like bamboo toothbrushes exist to monetise that concern, but because they’re sold in plastic and shipped around the world, their production and distribution still consumes fossil fuel and does nothing to change the existing economic or political system that is fuelling climate change. A collective challenge to political and economic elites is likely to be more effective in forcing this transition.
When aspects of horizon three appear – glimpses of a more sustainable system – they are usually rejected as illegitimate or too radical. When Rosa Parks sat down at the front of the bus in a move to promote civil rights in America in 1955, she was condemned. Looking back after system change has happened, these people are seen as leaders.

The end of capitalism?
The system that needs to be changed to avert climate disaster is capitalism, which is losing its legitimacy largely due to the system’s failure to respond effectively to climate change.
Applying all I’ve learned about how systems change, it’s possible to imagine that the current system which sustains business-as-usual capitalism – horizon one in the framework – is occupied by those who continue to produce, sell and consume products and services that rely on fossil fuels. That’s most of us, but horizon one is also maintained by climate deniers and investors in fossil energy, who, despite the scientific evidence, keep chugging along.
A more sustainable system could include policies we might currently consider “extreme”, like universal basic income. This is a guaranteed payment for all people regardless of their wealth which could help break the cycle of production and consumption that pollutes the atmosphere and fills the ocean with discarded plastic. Evidence suggests there is growing support for this, particularly among young people.

Extending human rights to non-humans and even to ecosystems is another idea that seems radical today but is gaining traction and could define an alternative system in future. One thing is for sure, we’ll look back in horror one day at how humans treated the natural world, as many already do in the present.
If the climate strikers can continue to grow their movement and sustain momentum, their leadership could be an important part of society’s transition to a more sustainable system in horizon three.
Capitalism may seem permanent, but research shows that systems inevitably change over time, and are ultimately created and reinforced by us. But in order to change anything, people must question their own role in the system first.

As The Climate Warms, Heat Is Building On Politicians To Respond

Fairfax - Nicole Hasham

You don’t need to be a climate scientist to know that something was different this summer. Overheated flying foxes dropped from the sky. Fruit cooked on trees. Roads melted, moods changed. The weather was on the rampage, and Australians could no longer deny that humans have irretrievably warmed our world.
The freakish summer – Australia’s hottest on record – is burnt into the minds of voters as they head to the ballot box in May for what many believe will be a federal election decided on climate policy. Polls show that voter concern over climate change is the highest in more than a decade. And the window of time left to avert the worst disasters is fast closing.
Labor frontbencher Mark Butler, who on current polling will hold the climate change and energy portfolio come May, says voters are increasingly clear that global warming "is real and it's manifesting now".

"From a South Australian perspective, which is where I’m from, it was the hottest summer, we had the hottest month and the hottest day [on record]," he says.
"People are really seeing the evidence of climate change and the advice is just becoming clearer and more urgent."
After a punishing last two terms in government, Labor knows better than most that voter concern on climate change does not easily convert to a viable and enduring policy.
But Australian Industry Group principal national policy adviser Tennant Reed says the public broadly believes that "we have not done very well in Australia on climate policy over the past decade and we need to sort it out".
"There is a strong perception in industry that this is a matter of public concern, particularly among young people," says Mr Reed, whose organisation represents 60,000 businesses employing more than 1 million people.
"And there is an expectation that if governments are not seen to be addressing climate change they will pay an electoral price for that."
A Sydney Morning Herald poll this week that showed climate change and environmental protection will be top of mind for most voters at next weekend’s NSW election. Tens of thousands of students skipped half a day of school on Friday to demand more action on climate change, and internal party polling by the Nationals has also shown that the issue is a priority for voters in their federal seats.
But that public sentiment sits in staggering contrast to Australia’s contribution to global climate efforts. The nation’s carbon emissions are rising year on year. The collapse in 2018 of the National Energy Guarantee was the latest in a string of epic fails by Parliament on reaching climate consensus. And the Coalition this week continued to rip itself apart over funding new coal plants from the taxpayers’ purse.
Despite its internal divisions the government this month bent in the prevailing wind, injecting $2 billion into the emissions reduction fund and committing to a multibillion-dollar expansion of the Snowy Hydro project. Even Tony Abbott has reluctantly arrived at the party, backflipping on his insistence that Australia abandon the Paris climate accord.
Environment Minister Melissa Price said the government "understand[s] Australians are concerned by climate change, and we’ve been taking action since we came to government".
The Coalition would cut emissions by 26 per cent on 2005 levels by 2030 in line with the Paris treaty– a goal Ms Price says is "responsible and achievable".
Labor would go much further, setting targets of a 45 per cent emissions reduction and 50 per cent renewable energy by 2030.
Price said Labor was yet to release important details of its climate plans and repeated the government’s claim that the policies would "destroy whole sectors of the economy". She cited modelling released last month that suggested Labor’s policies would increase wholesale electricity prices by almost 60 per cent.
"This is not a scare campaign – it’s independent modelling which lays bare the cost of a 45 per cent target," she says.
Contradictory modelling cited by Labor has found its policies will push wholesale prices down.
Reed says modelling the economic impact of climate policies was notoriously difficult, and "we don’t think the evidence is terribly strong in any direction" on the effect of Labor’s policies. But the relative ease with which Australia met its Kyoto emissions targets were cause for hope, he says.
"We should be a little more optimistic about our capacity to make things work if we have a clear policy pathway that is ... plausibly going to be sustained," he says.
Labor remembers well the political punishment meted out to the Rudd-Gillard governments when the party walked away from an emissions trading scheme, then introduced a carbon price dubbed by Abbott as a "great big tax on everything".
But Butler believes Australians are increasingly cognisant that when it comes to climate action "the world is going in one direction and we are going in the other".
"[The government is trying] to pretend that everything is going fine and emissions are coming down and we are going to meet our Paris targets in a canter," he says.
"But an array of voices in the community – scientists, business, regulatory agencies, bodies who measure performance in this area - they are all saying Australia is underperforming."
A recent series of reports outlining the need for radical action, including sobering findings from the United Nations’ Intergovernmental Panel on Climate Change, has helped galvanise voter concern.
The Reserve Bank of Australia this week became the latest major financial regulator to highlight the potential economic harm if businesses do not immediately address the climate change risk.
Many businesses have already cottoned on. Among them are Australia's largest coal miner Glencore, which last month announced it would cap coal production at 2019 levels due to climate change concerns.
In contrast to government predictions of a Labor-induced economic apocalypse, the Greens have decried Labor for running a "small target" strategy that fails to deal with the burning problem of coal, including its fence-sitting on the proposed Adani mine.
Opposition Leader Bill Shorten has expressed scepticism over the economic and environmental credentials of the Adani project but has stopped short of committing to halt it should Labor win power.
On Thursday he said fossil fuels would be part of the Australia’s future energy mix and export industry, but emphasised that the nation "can't live in the past".
Labor must walk a politically risky line between appealing to voters in marginal Queensland seats who want the Adani mine to proceed, and not alienating progressive voters in inner-city seats who want serious action on climate change.
Greens climate and energy spokesman Adam Bandt says Labor "is trying their hardest not to talk about" coal.
"But I think over the next couple of months it will become increasingly impossible to either continue to promote coal or to be silent about it," he says.
Successive Newspolls suggest the Greens have not capitalised on voter concern on climate, showing their primary vote has not improved since their disappointing 10.2 per cent share in 2016. The party’s defeat in the Batman byelection did not augur well, and a public airing of divisions within the NSW Greens in recent months has not helped matters.
But Bandt does not believe the NSW issues will erode the federal Greens vote, and the Newspoll findings do not "gel" with his experience of talking to voters, who in particular recognised the need for a strong Greens presence in the Senate.
The Australian Conservation Foundation has been phoning and doorknocking voters in three marginal seats - Chisholm and Macnamara in Victoria, and Bonner in Queensland – to gauge the public mood on climate change.
The organisation’s chief executive Kelly O’Shanassy said people were more prepared than ever to "take action through their vote".
"People are looking at the cost of climate change in human terms and not just dollar terms," she says.
O’ Shanassy said of the policies announced so far, the Greens, predictably, had pledged the boldest climate action.
While Labor’s emissions targets and stance on coal were far from ideal, the party had "started to move into an area of having clearer climate policies" which may be thwarting a Greens resurgence, she says.
As Labor and the Greens tussle over the progressive vote, the Liberal Party is fending off challenges from pro-climate independents in a number of blue-ribbon electorates.
In the Melbourne seat of Kooyong, Treasurer Josh Frydenberg is up against former Liberal Party stalwart and ex-Clean Energy Finance Corporation chief Oliver Yates.
Yates says the government is "too busy arguing internally to genuinely help people manage their own electricity needs". Among his election pledges is a bid to encourage rooftop solar uptake through environmental upgrade agreements, whereby households can obtain a low-cost loan to install the infrastructure and pay it back via council rates.
Yates, a former Macquarie banker, says moderate Liberal voters are dismayed at the Coalition's climate inaction after it was "body snatched by the far right".
"The market that you are pitching to in an electorate like this is not rusted on Labor voters, you are actually filling the gap that the Liberal Party has left behind," he says.
As the long days of summer recede and autumn takes hold, climate change advocates will be hoping that public pressure for change does not cool with the temperatures ahead of the May election.
Reed says despite not seeing eye-to-eye on everything, business, unions, environmentalists investors and the social welfare sector put aside their differences years ago to agree on the best way forward on climate change. Now politicians must do the same.
"We all agree on the need to address climate change, to do so in a trade-neutral way, and to bring everybody along in the process in terms of equity," he says.
"There is a lot more consensus outside Parliament than in it."

Taking Up The Slack: When Governments Don’t Act On Climate Change

UNSW - Jeremy Moss

The responsibility for reducing emissions flows from federal to state to local governments, as well as to individual cities.
Jeremy Moss
Jeremy Moss is Professor of Political Philosophy and Co-Director of the Practical Justice Initiative, University of New South Wales.
Every year the governments of the world meet to progress action on climate change. And every year, governments recommits to take some sort of action to prevent climate change. That governments should make these commitments and then implement them is beyond question.
But the results have been dismal. Most nations not only have commitments that are well below what is required, they are also failing miserably to implement even the minimal policies they have agreed to. A recent article in Nature noted that global emissions increased by 2% in 2018 despite record take up of renewable energy.
Australia is not much better. We have agreed to reduce our emissions by 26-28% by 2030 against a (generous) 2005 baseline. Even granting that this is our ‘fair share’ (and it is not), governments at the national level are simply not doing enough. A government report released in December 2018 estimated that Australia’s emissions in 2030 will only be 7% below 2005 levels.
But the climate won’t wait for the federal government. The risks of climate change are increasing and we require an effective response – someone needs to take up the slack. But who?
One response has come from a collection of cities and states that are trying to do what their federal governments refuse to do. The C40 coalition (90+ cities representing 650 million people) including New York, London and Sydney have agreed to reduce their emissions in line with the ambitious elements of the Paris Agreement.
While it is good that cities and state governments act in this way, their actions should not be seen as optional – they are morally required. Some of the same considerations that apply to federal governments also apply to cities and state governments. Like their federal counterparts, they are agents who have resources and legitimate authority. They can make policies and have them endorsed by voters.
These ‘sub national’ actors are also big emitters. In 2014, NSW emitted 130Mt of C02e – more than twice as much as Portugal. It also exports large quantities of coal through the world’s largest coal port at Newcastle.
Some might object that we can’t ask smaller cities or states to do what the federal government will not do. But this can’t be right. Just as we would be horrified if someone at a beach sees a drowning swimmer and refuses to rescue them, claiming ‘it’s the lifeguard’s job’, we should not accept state governments looking on as the climate worsens.
State governments and cities (where most Australians live) are under an obligation to take robust action on climate change because federal duties ‘devolve’ to them.
State and local governments taking this kind of unilateral action also increases the likelihood of others doing so. If Victoria introduces green energy policies, that makes it easier for NSW or Western Australia to do so because they will know what works and what doesn’t. The costs also decline as economies of scale kick in.
Cities taking unilateral action can also create new norms around climate change. With each city that adopts transport, housing or energy policies that make emission reduction central, it creates expectations on others to follow. Just as the establishment of one of the world’s first national parks, the Royal National Park in 1879, created norms about preserving nature, so being an early adopter of local climate-friendly policies will create norms. NSW also introduced one of the world’s first GHG emission reduction schemes in 2003.
It would undoubtedly be better if federal governments took action. But as the urgency around climate change increases, we should not wait for our federal laggards. So as local and state elections roll around, we should ask each layer of government whether its policies do take up the slack. We need more world firsts from our governments.

Climate Change Sparks Fears For Flying Foxes After 23,000 Deaths

Fairfax - Felicity Caldwell

There are fears climate change will be devastating for flying foxes after a heatwave led to tens of thousands of animals perishing in Cairns.
In late November, wildlife carers reported about 23,000 spectacled flying foxes died – an estimated one-third of the total population – after temperatures rose above 42 degrees.

Volunteers and scientists believe it is the first time a major heat stress event has led to mass deaths of the spectacled flying fox, which is endemic to the north-eastern regions of Queensland.
Bats and Trees Society of Cairns president Maree Treadwell Kerr said it was "pretty catastrophic", with rescuers arriving at camps to find thousands of animals had dropped dead from trees.
Ms Treadwell Kerr said volunteers managed to rescue about 850 animals but were stretched thin as they already had more than 500 flying foxes in care.
"There had been a food shortage, which was probably due to the fact that it had been a very dry season and then they got the heatwave," she said.
"In one camp [at Edmonton], the whole camp was wiped out, and 11,000 animals, at least, died.
"And the flying foxes have not returned to that site yet even though since then we got a proper wet season for a change."
Ms Treadwell Kerr said flying foxes were good "indicators" for climate change and their deaths were more readily noticed than other animals which may also be affected by extreme heat.
"When they die, you see it, it's right there in front of them," she said.
"We were expecting it to happen at some stage – we weren't expecting it to happen in November."
At one camp alone, volunteers found 11,000 flying foxes dead.

In February, federal Environment Minister Melissa Price upgraded the spectacled flying fox from vulnerable to endangered on the national threatened species list.
CSIRO research showed the population of the spectacled flying fox had more than halved from 214,750 in November 2005 to 92,880 in November 2014.
Macquarie University ecologist Tim Pearson said flying foxes were a keystone species, an important pollinator and seed disperser and vital for the health of forests.
"One of the reasons flying foxes are so important, and this doesn't just apply to speccies [spectacled flying foxes], but other species in Australia as well, is they fly huge distances," he said.
"So when they lick the nectar out of eucalyptus [trees], all that fur gets covered in pollen and then they fly 20 to 30 kilometres.
"They pollinate the tree next to it but they pollinate trees far away so they ensure genetic diversity."
Mr Pearson said the increased frequency of heatwaves had led to more mass die-offs elsewhere in Australia.
Almost 50,000 flying foxes perished during extreme heat in 2014 in south-east Queensland, while there have also been deaths in Adelaide and Victoria in recent months.

in far north Queensland, mostly pups.

The Lab of Animal Ecology, led by Dr Justin Welbergen, reports mass casualties are occurring between zero to five times per year and the events are expected to escalate under climate change.
"Where they used to be very occasional events, now they're happening more and more often," Mr Pearson said.
"What was scary about the November instance in Cairns was that to the best of our knowledge, the spectacled flying fox, which just lives in north Queensland, has never been affected by heatwaves before ... They typically don't have heatwaves."
Mr Pearson said climate change meant days of extreme heat were becoming more frequent and more severe, which would lead to more flying fox deaths.
"Most of us who work with flying foxes ... are pretty convinced that their numbers are going to keep declining," he said.
"The pressures on them are climate change and habitat destruction - neither of those two pressures shows any signs of slowing down."
Official counts, revealed in Queensland open data, showed there were 1.4 million flying foxes of all species reported in the state in January to March 2016 and only 243,000 in January to March 2018.
However, a Queensland Department of Environment and Science spokesman said the data showed numbers from quarterly surveys of known roosts only and could not be used as an overall population estimate.
This is because of the nomadic nature of flying foxes.

for 500 flying foxes in care when the mass die-off occurred.

The spokesman said the department recognised that recent heatwave events had significant impacts on flying fox populations.
"Cyclones in north Queensland have also had a serious impact on flying fox food trees," he said.
The spokesman said the department was providing support and advice to councils across the region on the impacts of heat stress on flying foxes, and how to safely evaluate and record sick or dead flying foxes, in addition to financial assistance to flying fox carer groups.
People are urged not to touch flying foxes but instead contact a bat rescue group or RSPCA Queensland for advice.
