Scorched Earth, Dying Trees, and a Capital Under Siege: The Climate Crisis in Canberra - Lethal Heating Editor BDA

Key Points

Canberra is warming rapidly, with maximum temperatures rising 1.8°C since 1914 and extreme heatwaves becoming more frequent and severe.1 The ACT faces a dual threat of drying trends reducing water inflows and intense storms causing dangerous flash flooding in urban areas.2 Mental health crises are escalating, particularly among youth, driven by "climate distress" and trauma from events like the Black Summer fires.3 Native "Ghost Gums" (Snow Gums) and Blakely's Red Gums are dying en masse due to beetle infestations triggered by heat and drought stress.4 Economic pressure is mounting as home insurance premiums in high-risk zones surge by up to 50%, fuelling a cost-of-living crisis.5 Biodiversity is collapsing in river systems, with native fish populations in the Cotter River decimated by ash and sediment from bushfires.6

Canberra, once celebrated as the Bush Capital for its seamless integration of nature and city, is rapidly becoming a case study in the devastating acceleration of climate change.

The Australian Capital Territory (ACT) is heating faster than the global average, with maximum temperatures rising by over 1.8°C since records began in 1914.¹

This shift is not merely statistical; it is physically reshaping the landscape, turning lush reserves into tinderboxes and suburban streets into heat islands.

The predictable seasonal rhythms that defined life in the high country are dissolving, replaced by a volatile cycle of flash droughts and violent storms.

Residents are facing a new reality where extreme weather events, once generational outliers, are now frequent and compounding threats to safety and infrastructure.²

The "Black Summer" bushfires of 2019-20 stripped the city of its illusion of safety, choking the air with hazardous smoke and traumatising a population that believed it was insulated from the worst of the continent's climate fury.

Today, the ecological fabric of the territory is fraying, with iconic gum trees dying in vast numbers, their skeletal remains standing as ghostly monuments to environmental stress.⁴

The economic toll is mounting quietly but aggressively, manifested in soaring insurance premiums and a cost-of-living crisis exacerbated by climate risk.⁵

Water security, the lifeline of the inland capital, hangs in a precarious balance as catchments degrade and native biodiversity collapses under the weight of heat and sediment.⁶

As the city plans for a future of population growth, it faces an existential question: can the Bush Capital survive the very bush that surrounds it?

This is no longer a warning for the future; it is a hard-hitting report on a disaster currently unfolding.

The Heating Capital: A New Climate Reality

The meteorological data for the ACT paints a stark picture of a region undergoing rapid thermal acceleration.

Annual average maximum temperatures have surged, and nine of the ten hottest years on record have occurred since 2006, signalling a permanent shift rather than a temporary anomaly.¹

This warming is driving a dramatic increase in the frequency and intensity of heatwaves, which now arrive earlier in the season and linger longer, testing the limits of human physiology and urban design.

Rainfall patterns have become erratic and hostile; while the overall trend points toward drying, the rain that does fall often arrives in torrential bursts, overwhelming stormwater systems and causing dangerous flash flooding.²

The vulnerability of Canberra’s infrastructure was laid bare in recent years when intense storms snapped power grids and turned major roadways into rivers.

These compound events—droughts hardening the soil followed by floods washing it away—are destabilising the very ground the city is built upon.

The risk of catastrophic bushfire weather is escalating, with the window for safe hazard reduction burns narrowing as winters shorten and warm up.⁷

The Human Cost: Health, Minds, and Safety

The physical environment is not the only casualty; the health of Canberra’s residents is deteriorating under the strain of a changing climate.

The 2019-20 bushfire smoke event was a public health disaster, linked to an estimated 31 premature deaths and hundreds of hospital admissions for respiratory and cardiovascular conditions in the region.⁸

Beyond the physical lungs of the city, the psychological toll is profound, particularly among young people who are reporting surging rates of anxiety, depression, and "climate distress."³

Mental health professionals warn that this eco-anxiety is not a pathology but a rational response to an unstable future, compounded by the direct trauma of living through disaster events.

Emergency services are stretched thin, facing "disaster fatigue" as the respite periods between crises vanish.

Vulnerable populations, including the elderly and low-income earners, are increasingly trapped in energy-inefficient housing that becomes dangerous during heatwaves, creating a silent health emergency behind closed doors.⁹

Infrastructure Under Siege: The Economics of Risk

Canberra’s economy and infrastructure are facing a reckoning as the costs of climate resilience spiral.

Home insurance premiums in high-risk areas have jumped by up to 50% in a single year, pushing home ownership out of reach for many and leaving others under insured against the next catastrophe.⁵

This "insurance apartheid" is creating zones of financial exclusion, where only the wealthy can afford to protect their assets from flood and fire.

The cost of living is further inflamed by supply chain disruptions and rising energy costs associated with extreme weather, turning climate change into a direct hip-pocket issue for every household.¹⁰

Critical infrastructure, including the electricity network and transport corridors, is increasingly susceptible to damage from severe storms, necessitating expensive retrofits like those currently being integrated into the Light Rail extension project.¹¹

Without massive investment in adaptation, the city’s transport and power systems remain one severe storm away from failure.

Water and Wilds: Ecosystems in Collapse

The water security of the ACT, historically robust, is being undermined by the dual pressures of reduced catchment inflows and deteriorating water quality.

The enlarged Cotter Dam provides a buffer, but the water that fills it is increasingly threatened by sediment run-off from burnt landscapes, which chokes filtration systems and degrades potability.⁶

Beneath the surface, the ecological damage is severe; native fish populations in the Cotter River, such as the Macquarie Perch, have plummeted, replaced by resilient alien species like Carp and Rainbow Trout.⁶

The ecosystem is trapped in a feedback loop of destruction: fires strip the vegetation that holds the soil, and subsequent rains wash that soil into the rivers, suffocating aquatic life.

On land, the iconic Gang-gang cockatoo and the migratory Bogong moth are facing habitat collapse, signalling a broader unravelling of the biodiversity that defines the Territory.¹²

The Dying Trees: Ghost Gums and a Landscape Transformed

Perhaps the most visible scar of climate change in the ACT is the widespread dieback of its native eucalypts.

High-elevation Snow Gums (Eucalyptus pauciflora), often referred to locally as "Ghost Gums" due to their pale bark and now-spectral dead trunks, are being decimated by longicorn beetles.⁴

These beetles, which usually attack only stressed trees, have exploded in numbers as drought and heat strip the trees of their natural defences.

Similarly, Blakely’s Red Gums in the lower reserves are dying en masse, creating a landscape of grey, leafless skeletons that stretches across the nature parks.¹²

This dieback is not just an aesthetic loss; it represents a catastrophic failure of the carbon cycle and a massive accumulation of dry fuel, significantly increasing the intensity of future bushfires.

The "Ghost Gums" of the Australian Alps are becoming literal ghosts, disappearing from the skyline and taking with them the complex web of life they support.⁴

UN’s New Global Environment Outlook Issues Stark Warning and Signals a Crucial Moment for Australia - Lethal Heating Editor BDA

Key Points

World on path to exceed 1.5 °C warming in early 2030s under business-as-usual, risking biodiversity, land and health — and costly climate impacts. 1 Pollution, land degradation and resource-overuse now match climate change as core threats, with wide harms for human health. 2 Transforming energy, food, waste and economic systems could yield US$ 20 trillion per year by 2070—and avoid millions of deaths and poverty. 3 Australia’s ecosystems — including the Great Barrier Reef and bushfire-prone landscapes — remain vulnerable to climate change, overheating oceans and biodiversity loss. 4 The report calls for “whole-of-society” action, urging governments to integrate environmental, economic and social policies. 5 Time is running out: delayed action will escalate costs — both ecological and economic — and foreclose many restoration opportunities. 6

The new edition of the United Nations Environment Programme’s flagship environmental assessment has landed with a collective gasp. 

The seventh Global Environment Outlook 7 (GEO-7), released in December 2025, draws together the work of 287 scientists from 82 countries to deliver a sweeping verdict:

Without immediate, global systemic transformation, the planet is hurtling towards cascading environmental collapse.

Yet GEO-7 also offers something rare in environmental science: a roadmap towards a different future, one where healthier ecosystems, more stable climate and human well-being can go hand in hand.

For Australia, a country already suffering the consequences of extreme heat, coral bleaching and land degradation, the report is more than a wake-up call, it is a moment to re-think national environmental policy and long-term resilience.

Here is what GEO-7 finds, what it means for Australia, and why the next few years may be decisive for both.

Global Diagnosis: Interlinked Crises

GEO-7 emphasizes a central truth: what might once have been seen as separate problems — climate change, biodiversity loss, pollution, land degradation and resource overuse — are deeply entangled.

The report warns that if the world continues on its current trajectory, global average temperatures are likely to exceed 1.5 °C above pre-industrial levels in the early 2030s, breach 2 °C in the 2040s, and continue climbing thereafter.

That warming will exacerbate other threats. Land degradation, already affecting a large share of Earth’s terrestrial systems, is projected to intensify, undermining soil health, reducing agricultural productivity and accelerating biodiversity loss.

Pollution,  especially air pollution from fossil fuel combustion, industrial processes and waste mis-management, remains a major health risk. The report suggests that reducing pollution through systemic change could prevent millions of premature deaths.

Resource use has surged beyond sustainable levels. Since 1970, global resource extraction and processing have ballooned, driving over 60 per cent of global greenhouse-gas emissions and 40 per cent of pollution-related health impacts.

In sum, GEO-7 describes a “triple planetary crisis” that can no longer be tackled in isolated silos: the planet’s climate, nature and human health are intimately connected.

Pathways to a Better Future — And High Stakes for Delay

Yet GEO-7 does not resign itself to catastrophe. Rather, it argues that a timely shift in economic, energy, food, waste and finance systems could yield massive long-term benefits.

The report estimates that if societies adopt its “transformation pathways”, global macroeconomic benefits could start to appear around 2050, rising to about US$ 20 trillion annually by 2070, and continuing to grow thereafter.

Meanwhile, public health gains are striking. By 2050, tens of millions of premature deaths from pollution could be avoided, hundreds of millions of people could escape hunger or extreme poverty, and biodiversity decline could notably slow.

The changes required are sweeping: governments must phase out harmful subsidies, price the environmental cost of pollution and resource use, invest in clean energy and sustainable agriculture, overhaul waste and materials management, and embrace what GEO-7 calls “whole-of-government” and “whole-of-society” strategies.

Why GEO-7 Matters for Australia

Australia is not just a distant observer of global environmental change. As a continent-scale nation with fragile ecosystems, a high dependence on resource extraction, and a long history of climate extremes, the country sits at the front-lines of many of GEO-7’s warnings.

Take the Murray–Darling Basin, a vast inland river and farmland system that underpins much of Australia’s agriculture. Climate-driven shifts in rainfall, combined with land use pressures, make the Basin especially vulnerable to degradation, water stress, and collapse of biodiversity and agricultural productivity. 

While GEO-7 deals in global terms, the same dynamics it describes globally apply in the Basin — rising temperatures, shifting rainfall patterns, over-extraction of water, and ecosystem stress.

The report’s alarm about climate change resonating with biodiversity loss and pollution rings especially true for the Great Barrier Reef. Rising sea surface temperatures in 2024, reportedly the highest on record, triggered yet another major bleaching event, as documented by the national environmental assessment published earlier this year.

Beyond marine ecosystems, terrestrial landscapes in many parts of Australia face increased bushfire risk, prolonged droughts and heat stress,  a potent cocktail for land degradation, biodiversity loss and human vulnerability. GEO-7 underscores that such compound risks will intensify unless emissions, land-use and resource pressures are curbed.

On the flip side, GEO-7’s emphasis on transforming energy systems dovetails with Australia’s growing shift towards renewables. The rapid uptake of solar and wind power, and national ambitions to decarbonise, mean GEO-7’s warning that fossil-fuel dependence continues to undermine environmental and economic security should hit close to home for policymakers and citizens alike.

Voices from the Field: What Experts Are Saying

At the release in Nairobi on 9 December 2025, the Executive Director of UNEP described GEO-7 as a “clear choice for humanity”.

Many scientists, including several based in Australia, have echoed the urgency. A professor at the University of the Sunshine Coast, who contributed to the report, has urged the Australian government and society to act on the findings “to avoid an unsustainable future”.

One of the key messages that has reverberated globally, and in Australia, is the need to move beyond narrow measures of economic success, such as gross domestic product. GEO-7 recommends instead accounting for environmental and social costs and benefits, a shift that would make clear the long-term economic and human value of healthy ecosystems, clean air and stable climate.

Some environmental economists say such reframing remains politically difficult but vital. As one proclaimed in the report’s global summary: “There is no technical reason why a sustainable future cannot be built.” The challenge lies in political will, institutional coordination and social mobilisation.

What Australia Could Do — And What’s at Stake

For Australia, GEO-7 provides both a warning and a strategic compass. The government could use the report as a basis to deepen renewable energy investment, accelerate the phase-out of fossil fuels, protect and restore fragile ecosystems, and reform agricultural and land-use laws to reduce over-extraction of resources and prevent land degradation.

In practice, that might involve stronger protections for biodiversity, expanded funding for reef and ecosystem restoration, revisiting water rights and extraction rules in agricultural zones, and embedding environmental externalities into economic decisions.

Implementing a “whole-of-society” approach, as GEO-7 suggests, would also require new levels of coordination across federal, state and local government — and engagement with industry, Indigenous communities, landowners and citizens.

The stakes are high. If Australia ignores the warnings, the costs — in ecological damage, lost economic potential, public health harms and social dislocation — could escalate rapidly. If it acts now, the country could contribute to a global transition that promises both environmental security and long-term prosperity.

Looking Ahead: A Crossroads for the Planet — and Australia

GEO-7 makes clear that the world stands at a crossroads. One path leads to worsening climate breakdown, accelerating biodiversity collapse, widespread land degradation and mounting pollution, with heavy consequences for human health, economic stability and social cohesion. The other offers a chance to un-couple development from environmental harm, building a resilient, healthier world rooted in sustainable practices and systemic transformation.

For Australia, the coming decade may determine whether the damage to iconic ecosystems such as the Great Barrier Reef becomes irreversible or whether restoration and adaptation can offer a future worth inheriting. The choices made now matter.

GEO-7 delivers a simple yet powerful message: the window for effective action is narrowing. Delay is not just dangerous, it may close off many of the options that remain.

Ghost Forests and Squeezed Shores: Australia's Climate Tipping Points - Lethal Heating Editor BDA

Key Points

Snow gum ghost forests emerge from repeated bushfires1 Short fire intervals block snow gum regeneration1 Longicorn beetles thrive in warmer, drier conditions3 Coastal squeeze traps mangroves against infrastructure4 Mangrove loss erodes blue carbon and fish habitats6 Bramble Cay melomys marks first climate mammal extinction5

In Australia's alpine regions, ridges of bleached grey trunks stand where snow gums once thrived.

These ghost forests signal the collapse of ecosystems under climate stress.

Snow gums in the Victorian High Country now die en masse after back-to-back bushfires. 

Elsewhere, coastal mangroves face a relentless squeeze from rising seas blocked by human barriers.

Along shorelines, skeletal mangrove trunks mark permanent habitat loss. 

Such changes threaten water flows, biodiversity, and defences against storms.

Across Australia, warmer conditions favour longicorn beetles that ringbark weakened trees.

In the Torres Strait, the Bramble Cay melomys have vanished from their island home, the first mammal lost primarily to human-driven climate change.

Alpine Ghost Forests Rise

Ridges once cloaked in twisting snow gums now reveal stark white skeletons.

Dead Eucalyptus pauciflora trees create haunting ghost forests across the Victorian High Country.¹

Climate change drives more frequent and intense bushfires in these highlands.

Snow gums re-sprout from lignotubers after fire, drawing on stored carbohydrates.

Yet shorter intervals between blazes exhaust these reserves before trees mature.¹

Over 90 percent of snow gum habitat burned at least once in the past 20 years.⁷

Failed regeneration shifts woodlands to grass and shrub lands.

These trees capture blowing snow and fog, moderating melt for downstream rivers.

Their loss reduces snowpack and spring stream flows vital to southeast Australia's water security.³

Beetles Accelerate Dieback

Even unburned snow gums succumb to native longicorn beetles.

Warmer, drier air stresses trees, drawing moisture from bark and wood.³

Beetle larvae bore into cambium, ringbarking trunks and halting water flow.

Healthy trees gum-up bore holes to drown invaders.

Drought-weakened ones fail, allowing outbreaks that spread rapidly.⁹

Such dieback appears across Victoria, New South Wales, and the Australian Capital Territory.

Combined with fires, this perfect storm pushes ecosystems toward collapse.⁸

Coastal Squeeze Traps Wetlands

Sea-level rise pushes mangroves and salt marshes inland.

Seawalls, roads, and farms block this retreat, creating coastal squeeze.⁴

Mangroves encroach on salt marshes, which accrete too slowly to keep pace.

Permanent loss follows as habitats drown or convert.

These ecosystems nurse fish, feed birds, and shelter invertebrates.

Their decline ripples through food webs and fisheries.⁶

Mangroves also buffer shores from storm surges and erosion.

They store vast blue carbon, locked in muddy roots.

Bramble Cay's Lost Rodent

Tiny Bramble Cay in the Torres Strait hosted a unique melomys.

Rising seas and storm surges flooded its succulent food plants.

Surveys found no trace of the rodent by 2016.⁵

Experts deem it the first mammal extinction from human-induced climate change.

Low-lying islands worldwide face similar fates.

Global Warnings from Australia

Australia's ghost forests echo die-offs worldwide.

Alpine species struggle as climates warm faster than they migrate.

Coastal squeezes threaten 20 percent of global salt marshes.

These shifts expose systemic risks to water, food, and human settlements.

Paths Forward

• Ghost forests and squeezed coasts reveal rapid, often irreversible climate harms.
• Scientists urge deep emissions cuts to slow warming.
• Adaptation demands landscape planning to free coastal retreat paths.
• Protect unburned refuges and restore stressed woodlands.
• Communities map dieback to guide interventions.³
• Such steps can limit further collapse.

Climate fault lines: how policy paralysis is pushing Australia’s ecology to breaking point - Lethal Heating Editor BDA

Key Points

Escalating heat, fires and floods are pushing Australian ecosystems beyond their capacity to recover.1 The Great Barrier Reef has suffered five mass bleaching events since 2016, driven by record ocean heat linked to climate change.2 The 2019–20 Black Summer bushfires burned millions of hectares and affected billions of animals, with hundreds of threatened species in the fire zone.3 National environment laws have allowed extensive land clearing and more than 750 fossil fuel projects over 25 years, weakening ecological resilience.4 Scientists say Australia’s current emissions targets fall short of a pathway consistent with limiting warming to 1.5 degrees.5 Indigenous cultural burning and regenerative agriculture are restoring Country and building resilience, but operate at a far smaller scale than climate harms.6

Australia’s ecological systems are being reshaped by climate change faster than governments are willing to curb emissions or protect habitat.¹

From the Great Barrier Reef to alpine forests, repeated heatwaves, bushfires, droughts and floods are eroding resilience and pushing species towards collapse.¹

Scientists now warn that record marine heat and back‑to‑back coral bleaching events have placed the Reef in danger after the warmest ocean conditions in at least four centuries.²

On land, the Black Summer megafires burned more than 8 million hectares across south‑eastern Australia, with billions of native animals affected and hundreds of threatened species caught in the flames.³

Yet national environment laws have continued to permit extensive land clearing and the approval of coal, oil and gas projects whose emissions accelerate the very risks those laws are meant to manage.⁴

Independent analyses find that Australia’s current emissions targets and policies remain out of step with pathways consistent with the Paris Agreement’s 1.5 degree limit, even as climate impacts intensify.⁵

Across the continent, Indigenous land managers and regenerative farmers are demonstrating how cultural burning and soil‑centred agriculture can restore Country and buffer communities against climate shocks, but their efforts remain dwarfed by the scale of national inaction.⁶

What is at stake now is whether policy makers will match the urgency on the ground or preside over an avoidable unravelling of Australia’s unique biodiversity.¹

Ecological systems under climate stress

Australia sits at the frontline of climate disruption, where rising temperatures amplify drought, heatwaves, intense rainfall and dangerous fire weather across an already variable continent.¹

These overlapping hazards are transforming ecosystems faster than many species can adapt, shortening recovery times between shocks and increasing the risk of local extinctions.¹

Scientists describe a pattern of compounding pressures, where heat‑stressed forests become more flammable, degraded rivers struggle through longer dry spells, and marine heatwaves trigger mass mortality on coral reefs.¹

For ecologists, the concern is not only the severity of individual events but the speed at which they now recur, leaving little time for habitats to recover structure and function before the next crisis hits.¹

Great Barrier Reef: repeated bleaching as a warning

The Great Barrier Reef, long celebrated as a global biodiversity icon, has endured a series of mass coral bleaching events since 2016, driven by marine heatwaves linked to human‑caused climate change.²

Australian researchers report that severe back‑to‑back bleaching in 2016 and 2017 affected around two‑thirds of the Reef, killing large areas of shallow‑water corals and shifting the composition of many reefs.⁷

A recent study in the journal Nature concluded that the ocean temperatures behind these bleaching episodes were the warmest in at least 400 years, and that the events are clearly attributable to greenhouse gas emissions from human activity.²

Government monitoring has documented periods of partial recovery, with coral cover increasing in some regions, but scientists caution that these gains are fragile as more frequent and intense heatwaves shorten the window for regrowth.⁸

Each new bleaching event, now five since 2016, strips away older, slower‑growing corals, undermining reef complexity and the habitat that supports fisheries and tourism along Australia’s tropical coast.²

Black Summer and the fire frontier

The 2019–20 Black Summer bushfires marked a turning point in Australia’s understanding of climate‑driven fire, burning on a scale not recorded in south‑eastern forests for at least two centuries.⁹

Analyses of satellite and field data indicate that the fires scorched more than 8 million hectares of vegetation across eleven bioregions, including large areas of eucalypt forest, woodland and rainforest.⁹

One national assessment estimated that the fires affected about 3 billion native animals, while hundreds of listed threatened species and ecological communities lost significant portions of their habitat.¹⁰

In Victoria alone, state surveys suggest that more than 1.5 million hectares burned, with at least 244 species losing over half of their habitat area, underscoring the long‑term biodiversity risk.¹¹

Ecologists warn that repeated large fires in short succession can permanently alter vegetation, converting wet forests to more flammable states and exposing fauna to predators and invasive species as cover disappears.⁹

Heatwaves, droughts and floods: compounding pressures

Beyond headline disasters, Australia’s ecology is being quietly worn down by a pattern of hotter heatwaves, longer droughts and more intense downpours that follow one another in quick succession.¹

During extended dry periods, rivers contract, wetlands shrink and soil moisture declines, stressing plants and animals and setting the stage for more severe fires when extreme heat arrives.¹

When intense rainfall eventually falls on fire‑damaged or overgrazed catchments, it can trigger erosion, sediment pulses and fish kills, further degrading rivers, estuaries and coastal ecosystems already under strain.¹

These swings between extremes, known to scientists as climate variability on steroids, are occurring against a backdrop of steadily rising average temperatures that shift the baseline for every ecosystem.¹

Fossil fuels, weak laws and land clearing

Australia’s national environment law, the Environment Protection and Biodiversity Conservation Act, has long been criticised for failing to grapple with climate change and for allowing major habitat loss to continue.¹²

Environmental groups report that more than 750 coal, oil and gas projects have been approved under the Act over the past 25 years, with no requirement for the minister to fully consider the climate pollution and its ecological consequences.¹²

Analysis by the Climate Council notes that existing loopholes have also permitted extensive land clearing and native forest logging without assessment, even though clearing more than 400,000 hectares a year contributes to emissions and biodiversity decline.¹²

While recent reforms promise to phase out key exemptions for land clearing and forestry within about 18 months, legal commentators warn that the system still risks fast‑tracking some large projects before robust national standards are fully in place.¹³

At the same time, approvals for new fossil fuel projects continue in parallel with climate pledges, effectively baking in additional emissions that will expose ecosystems to higher long‑term warming.¹⁴

Climate targets versus scientific warnings

Australia has legislated a 2030 emissions reduction target of 43 per cent below 2005 levels and a goal of net zero by 2050, but independent scientific assessments say this is not aligned with a 1.5 degree pathway.⁵

Climate analytics organisations estimate that to play its fair part in limiting warming to 1.5 degrees, Australia would need to cut emissions by around 70 per cent or more by 2030 and adopt a much steeper trajectory through the 2030s.¹⁵

One detailed study comparing current policies with 1.5 degree‑consistent pathways concludes that the federal strategy could produce more than double the cumulative emissions budget compatible with a 50 per cent chance of staying below that threshold.¹⁶

Climate Action Tracker’s latest rating finds that, even after recent policy updates, Australia’s overall effort remains short of what is needed, particularly because coal and gas expansion undermines domestic cuts and drives warming globally.¹⁷

Indigenous land management: cultural burning and healing Country

Long before European colonisation, Aboriginal and Torres Strait Islander peoples used cultural burning to shape landscapes, promote biodiversity and reduce the risk of uncontrollable wildfires.¹⁸

Recent research combining ecological and archaeological data shows that the expansion of Indigenous cultural burning in the past reduced shrub cover in some forests by about half, lowering the likelihood of high‑intensity canopy fires.¹⁹

Studies comparing Indigenous‑led burns with agency‑run prescribed burns suggest that cultural burning, often conducted at lower temperatures and in more targeted patterns, can enhance soil health and increase carbon and nitrogen in the topsoil.²⁰

Programs supported by Indigenous ranger groups and conservation organisations report that cultural burning helps regenerate native plants, protect animal habitat and maintain tree canopies that shelter species from extreme heat.²¹

Despite these successes, cultural fire management still operates across a fraction of the landscapes that burned in Black Summer, limiting its current ability to counteract the elevated fire risk under climate change.⁹

Farmers and regenerative practices on the frontline

Across farming regions, producers are beginning to adapt to more volatile seasons by shifting to regenerative agriculture practices that focus on soil health, groundcover and water retention.²²

State‑led programs such as New South Wales’ Farming for Change have helped landholders adopt techniques that increase soil organic matter, improve water infiltration and maintain grass cover during droughts.²³

Landcare groups describe regenerative agriculture as a holistic approach that keeps water in the landscape, stores carbon and increases biodiversity, offering both productivity and resilience gains as climate impacts intensify.²⁴

Economic case studies from Australian grazing enterprises show that conservative stocking and better groundcover management can stabilise farm income in poor rainfall years while reducing erosion and land degradation.²⁵

Yet many farmers remain exposed to policy uncertainty, with climate‑driven floods and droughts damaging infrastructure and markets faster than support for large‑scale landscape repair and emissions reduction is rolled out.¹

Communities carrying the burden of delay

Frontline communities, from reef‑dependent tourism operators to rural towns in fire‑prone forests, are already living with the social and economic fallout of ecological decline.¹⁰

Black Summer exposed gaps in disaster planning for wildlife carers, rural health services and Indigenous communities, prompting ad hoc recovery funds and expert panels rather than the systemic risk reduction that scientists had long urged.¹⁰

For many First Nations communities, climate impacts compound existing injustices, damaging Country that holds deep cultural and spiritual significance and disrupting traditional practices that depend on seasonal cycles.¹⁸

Local councils and community groups have moved ahead with climate adaptation and habitat restoration projects, but they often lack the authority and funding to address root causes such as national emissions and land clearing policies.¹²

What is at stake if policy gaps persist

Australia’s ecological future now hinges on whether federal and state governments are willing to close the gap between scientific warnings and policy reality on emissions, land clearing and environmental regulation.⁵

Without much steeper and faster emissions cuts, the country faces more frequent marine heatwaves, more severe bushfire seasons and tightening bands of drought and flood that will test ecosystems already pushed to their limits.¹

If national environment laws continue to allow large‑scale fossil fuel expansion and habitat loss, efforts by Indigenous land managers, ecologists and regenerative farmers will struggle to keep pace with the damage unleashed by a hotter climate.¹²

Conversely, aligning climate targets with 1.5 degree‑consistent pathways, enforcing strong nature protection standards and scaling up Indigenous‑led and community‑based restoration could still avert the worst outcomes for many species and landscapes.¹⁶

The choice is stark but clear, and what governments decide over the coming decade will determine whether Australia’s living systems are safeguarded or sacrificed in the name of short‑term economic interests.⁵

It’s the first week of summer (December 2025) and we’re already living the script: dangerous heat, fires ripping through communities, homes destroyed, evacuations, and governments activating disaster assistance.

PM Anthony Albanese is already out there posting photos spruiking government support.

Yes, recovery support matters. People need immediate help, and they deserve it.

But here’s the brutal truth: recovery cheques won't stop the next fire. Prevention will. And that means cutting emissions fast, not expanding the very industries that load the atmosphere with more heat.

The carbon ledger Labor doesn’t want on the evening news

Since forming government in 2022, the Albanese Government has approved 32 coal and gas projects. The Climate Council estimates the combined lifetime pollution from these projects — counting both the emissions produced on-site and those released when the exported coal and gas are burned — will exceed 6.5 billion tonnes of CO₂-e.

That number isn’t a rounding error. It’s a deliberate choice: to keep expanding fossil fuels while our continent burns. And yes, it includes exports. The atmosphere doesn’t care where the coal is burned. Heat is heat whether it’s emitted in Newcastle, Osaka or Shanghai.

6.5 billion tonnes is equivalent to the total emissions of all Australian families for over 30 years. That’s the scale we're talking about — while Albo gets a chance to spruik disaster payments after the fact.

Moral responsibility sits at the top

No one is claiming the PM personally signs off on every approval. But the responsibility is still his. Because this is the government he leads, the priorities he sets, and the political cover that makes the approvals “normal”. When a government chooses to expand fossil fuels, it’s also choosing:

• More heat in the system
• More extreme fire weather
• More pressure on emergency services
• More trauma for families
• More risk pushed onto our children

That isn’t just hypocrisy. It’s a failure of duty.

And the defence you hear — “don’t worry, the Safeguard Mechanism will handle it” — doesn’t cut it. The Climate Council’s analysis is blunt: no federal law currently allows a coal or gas project to be stopped because of its climate harm. So we end up with governments funding recovery with one hand while locking in damage with the other.

What leadership should look like (starting now)

If the PM really wants Australians to believe his recovery rhetoric, he needs to match it with prevention:

1. Stop approving new coal and gas projects — not “offset”, not “abate later”, just stop.
2. Add climate impacts to national environment laws so projects can be refused on genuine climate grounds.
3. Put kids and Country above fossil fuel donors and exporters — because what we’re living through this week isn’t an anomaly. It’s the bill arriving. And it’s going to get much worse.

Australia’s Net-Zero Crossroads: Big Targets, Unanswered Questions - Lethal Heating Editor BDA

Key Points

Net zero by 2050 is locked in by law, but the pathway across sectors remains contested.1 Modelling shows multiple feasible transition pathways with very different infrastructure and land-use footprints.2 Reforms to the Safeguard Mechanism tighten emissions limits for big polluters yet lean heavily on carbon credits.3 Equity concerns are growing as households, regions and workers face overlapping climate and cost-of-living pressures.4 Carbon farming and land sector offsets are expanding, while experts warn on integrity, permanence and scale limits.5 The OECD and domestic advisers urge a clearer mix of carbon pricing, regulation and public investment to steer the transition.6

Australia has a legislated net-zero target and a suite of new climate policies, yet fundamental questions still hang over how the country will actually make the transition. ¹

Behind the headline goal, officials, analysts and communities are wrestling with the best economic pathway to cut emissions while protecting living standards and competitiveness. ⁴

Independent modelling reveals that different combinations of renewables, transmission, electrification and clean fuels can all deliver net zero, but they carry sharply different costs, land demands and regional impacts. ²

The federal government has retooled the Safeguard Mechanism to force down emissions from more than 200 of the nation’s heaviest industrial polluters, yet the reforms still permit extensive use of carbon credits in place of on-site cuts. ³

At the same time, community concern about fairness is mounting, as climate-driven disasters and rising energy and housing costs collide with uneven access to clean technologies. ⁴

Carbon farming and other land-based offset projects are promoted as a critical part of the solution, though expert reviews highlight unresolved questions about the integrity, permanence and appropriate scale of such schemes. ⁵

International bodies and domestic advisory agencies now argue that Australia needs a more coherent mix of carbon pricing, regulation and public investment to guide industry and households through the transition, rather than relying on piecemeal measures and opaque markets. ⁶

As Canberra prepares updated sector-by-sector plans, the hard choices over who pays, who benefits and how much can be left to markets are moving from modelling reports into live political terrain. ⁶

The pathway puzzle

Australia’s Climate Change Act now locks in an economy-wide target of cutting greenhouse gas emissions to 43 per cent below 2005 levels by 2030, and reaching net zero by 2050, but the law does not prescribe a single route for getting there. ¹

Large-scale modelling by the Net Zero Australia project, led by the University of Melbourne, the University of Queensland and Princeton University, finds that several distinct combinations of technologies can achieve net zero, ranging from a domestically focused transition to scenarios where Australia becomes a vast exporter of hydrogen and other clean energy products. ²

Those scenarios differ sharply in required investment, with the most export-intensive pathways demanding many trillions of dollars in new generation, transmission and processing infrastructure across remote regions. ²

The OECD’s 2024 economic survey of Australia warns that transforming an electricity system still dominated by coal while decarbonising emissions-intensive mining, industry and agriculture will be challenging, and stresses that clear long-term signals and credible sectoral plans are vital to mobilise private capital at scale. ⁶

The federal government has committed to update its Net Zero 2050 plan with detailed pathways for electricity, transport, industry, resources, agriculture, land and the built environment, but those sectoral blueprints are still under development. ⁶

Cutting fossil fuel use across sectors

The electricity sector is moving fastest, with state and territory commitments to retire government-owned coal plants and build out renewables and storage, yet coal and gas still supply a large share of generation and backup, leaving consumers exposed to volatile fossil fuel prices. ⁶

Transport emissions have risen over recent years, as growing vehicle use has offset efficiency gains, and Australia remains behind comparable economies on electric vehicle uptake despite new fuel efficiency standards and incentives starting to narrow the gap. ⁶

Industrial sites covered by the Safeguard Mechanism, including LNG facilities, steelworks, refineries and large mines, account for almost a third of national emissions, making their decarbonisation central to any credible net-zero strategy. ³

A reformed Safeguard scheme now sets declining emissions baselines for roughly 215 large facilities, with default reductions of 4.9 per cent per year to 2030, and allows firms to trade Safeguard Mechanism Credits if they cut emissions below their baseline. ³

While these changes are expected to drive material cuts, legal and policy experts note that there is no hard cap on the use of external offsets, raising concerns that some operators may delay investment in deep on-site abatement. ³

Equity and the cost of transition

As the net-zero agenda collides with a cost-of-living crunch, distributional questions are moving to the centre of the debate over how fast to phase out fossil fuels and who should bear the adjustment burden. ⁴

Research by the National Housing Supply and Affordability Council shows that many households are already trading off other essential spending, living further from jobs or putting up with substandard housing as rents and energy costs rise, with low-income and First Nations households facing the most acute pressures. ⁴

The council warns that failing to integrate climate resilience and energy performance into new and existing housing will impose higher long-run costs on vulnerable groups, who are more likely to live in dwellings with poor heating, cooling and weather protection. ⁴

The 2024 State of Australia’s Regions report highlights that regional economies built around coal, gas and emissions-intensive industries face layered risks from global decarbonisation, and stresses the need for coordinated federal, state and local investment in skills, infrastructure and services to support a just transition. ⁷

Surveys by think tanks such as The Australia Institute indicate that most Australians want stronger climate action, but also expect governments to ensure that large corporations, rather than households alone, shoulder a fair share of the costs. ⁸

Carbon farming’s contested role

Land-use change and agriculture together generate a significant slice of Australia’s emissions, yet the land sector also provides some of the country’s most prominent options for removing or offsetting carbon. ⁶

Over the past decade, the government has used the Emissions Reduction Fund and its successor, the Australian Carbon Credit Unit framework, to pay for projects such as reforestation, avoided deforestation, improved savanna fire management and changes to farming practices, often described under the broad banner of carbon farming. ⁵

An independent review of Australia’s carbon credit system, led by former chief scientist Ian Chubb, concluded in 2023 that the scheme was fundamentally sound but recommended tighter methods, more transparency and stronger governance to ensure credits reflect real and additional emissions reductions. ⁵

The OECD notes that achieving net zero will likely require a combination of steep cuts in fossil fuel use and significant “negative emissions” from land-based activities, but cautions that relying too heavily on offsets could delay necessary structural change in high-polluting sectors. ⁶

Critics from academia and civil society argue that carbon farming projects can clash with biodiversity goals, cultural values and local land rights if poorly designed, underscoring the need to embed integrity safeguards and community participation as the market expands. ⁵

Markets, mandates and the role of government

Australia’s current policy mix leans on a blend of market-based instruments, such as tradable carbon credits under the Safeguard Mechanism and the Australian Carbon Credit Unit scheme, combined with targeted regulation and public funding. ³

The government has established a national Net Zero Authority to coordinate support for workers and communities through the energy transition, recognising that market forces alone will not manage regional dislocation or deliver timely investment in enabling infrastructure. ⁷

International institutions including the OECD urge Australia to strengthen carbon price signals across the economy, for example through more consistent emissions pricing and fuel taxation, while using complementary standards and subsidies to accelerate low-carbon innovation and protect vulnerable groups. ⁶

Domestic advisory bodies such as the Climate Change Authority are developing sectoral pathways that combine regulatory standards, planning reforms, market tools and direct public investment, reflecting a shift away from the idea that markets alone can deliver an efficient and equitable transition. ⁹

The unresolved question is how far elected governments are willing to go in reshaping markets, setting hard limits on fossil fuel expansion and underwriting large-scale public works, as global competition for clean energy industries intensifies. ⁶

What remains unclear

Despite a clearer national target and an expanding policy toolkit, there is still no settled consensus on how quickly Australia should scale back its role as a major exporter of coal and gas, or how the risks of stranded assets and lost revenue should be shared. ⁶

Key design questions around the Safeguard Mechanism, including the future trajectory of baselines and the appropriate balance between on-site abatement and offsets, will determine whether the scheme locks in steady decarbonisation or delays it. ³

Similarly, while modelling shows that multiple net-zero pathways are technically feasible, choices about the scale of new export industries, the pace of electrification and the location of infrastructure will shape whether regional communities see opportunity or upheaval. ²

For households, the intersection of climate policy with housing, transport and energy markets will decide whether the transition eases or deepens existing inequalities, especially for renters, low-income families and First Nations communities. ⁴

With updated sector plans due and international partners tightening their own climate rules, Australia’s unresolved debates over policy design, equity and the role of carbon farming are set to define the next phase of its net-zero journey. ⁶

Finding Moral Ground in a Warming World - Lethal Heating Editor BDA

Key Points

Environmental ethics asks whether nature has value only for humans or an intrinsic worth of its own.1 The climate justice debate turns on who caused the problem, who benefited from it, and who can best afford to fix it.2 Polluter pays and beneficiary pays principles both seek to link responsibility to past emissions and their rewards.3 Equal per capita emission ideas treat the atmosphere as a shared global commons for all people.4 Intergenerational equity holds that each generation should meet its needs without undermining the life chances of those to come.5 The precautionary principle urges early climate action even when some impacts remain uncertain.6

Climate change is forcing a profound moral reckoning about how humans relate to the rest of the living world and to each other across borders and generations.¹

Beyond graphs of warming trends and economic models, environmental philosophy asks who and what matters morally when the planet heats up, and why.¹⁰

At the centre of this debate is a clash between anthropocentric views that value nature mainly for its usefulness to people and ecocentric perspectives that see ecosystems as having worth in their own right.¹

Climate justice principles then ask how to share the costs of cutting emissions and coping with damage, weighing historic pollution, the benefits of fossil fuel growth, and the unequal wealth of countries.²

Ideas such as polluter pays, beneficiary pays, ability to pay and equal per capita emission rights offer competing answers to who owes what to whom in a warming world.³

Intergenerational ethics extends this debate forward in time, arguing that today’s decisions lock in risks and opportunities for people who are not yet born.⁵

For many, these questions also carry an existential weight, as communities confront eco-anxiety and search for meaning and responsibility in the Anthropocene.⁷

Together, these philosophical lenses do not replace science and policy but shape what counts as a fair and decent response to the climate crisis.¹⁰

Anthropocentrism and ecocentrism

Environmental ethics often starts by asking whether humans sit at the moral centre of the world or whether whole ecosystems deserve direct moral concern.¹

Anthropocentrism treats humans as the primary bearers of moral value and tends to see non‑human nature in terms of the benefits it provides to people, from food and water to cultural meaning.¹

In climate policy, an anthropocentric approach often frames action as necessary to protect human health, livelihoods and security, including avoiding extreme heat, sea‑level rise and disrupted food systems.¹⁰

Ecocentrism, by contrast, assigns intrinsic value to ecosystems, species and even non‑living elements, arguing that they matter morally whether or not they are useful to humans.⁷

Ecocentric thinkers stress the interdependence of living systems and urge limits on human activity that degrades ecological integrity, even when such activity delivers clear short‑term economic gains.¹

Debates between these camps influence whether policies focus on managing nature as a resource or on restoring and protecting ecosystems as communities of life in their own right.⁴

Climate justice and fair shares

Climate justice asks how to share the burdens and benefits of climate action among states, communities and individuals in ways that respect basic fairness.²

The polluter pays principle holds that those most responsible for greenhouse gas emissions should bear a larger share of the costs of cutting pollution and dealing with the damage it causes.³

Supporters argue that making major emitters pay internalises the costs of pollution and discourages further harm, but critics note that many past emissions occurred before the science of climate change was widely understood.⁵

The beneficiary pays principle shifts focus from blame to benefit, suggesting that those who have gained most from carbon‑intensive development should help cover the resulting losses and adaptation needs, even if they did not knowingly cause the harm.⁸

Some theorists also defend an ability to pay principle, which assigns greater financial obligations to richer states and actors on the grounds that they can cut emissions and fund adaptation with less hardship.²

In practice, climate agreements often blend these ideas, recognising both different contributions to the problem and different capacities to respond.⁵

Equity, egalitarianism and the global commons

Equity in climate ethics also raises questions about how to divide the limited remaining carbon budget consistent with keeping warming within agreed thresholds.¹⁰

One influential proposal treats the atmosphere as a global commons and argues for equal per capita emission rights, giving each person an identical claim to the capacity of the air to absorb greenhouse gases.⁴

Supporters see this as a straightforward application of human equality, while critics point to practical obstacles in tracking and enforcing individual emission shares across borders and sectors.⁴

Others argue for priority to the basic needs of poorer populations, even if this means allowing higher per capita emissions in low‑income countries for a time while wealthier states decarbonise more steeply.²

These disputes feed into negotiations over carbon budgets, climate finance and the pace at which different economies are expected to phase out fossil fuels.⁵

Intergenerational ethics

Intergenerational ethics brings future people into the circle of moral concern, stressing that climate decisions today will shape conditions for many decades and centuries.⁵

The idea of intergenerational equity holds that each generation should meet its own needs while maintaining at least comparable options and environmental quality for those who follow.⁹

Legal and philosophical accounts often distinguish between fairness within a single generation and fairness between generations, noting that climate change intensifies both sets of tensions.³

Some frameworks identify duties to conserve critical natural capital, limit long‑lasting pollution and preserve cultural and ecological heritage so that future communities can pursue their own values and goals.⁹

In policy, this shows up in debates about discounting future harms, long‑term infrastructure planning and the design of institutions that can look beyond electoral cycles.¹⁰

Existential questions and eco-anxiety

For many people, climate change is not only a technical policy problem but an existential shock that challenges assumptions about progress, security and human dominance over nature.⁷

Psychologists and philosophers describe rising levels of eco‑anxiety and climate distress, particularly among young people who fear inheriting a more unstable and less predictable world.⁷

Some thinkers in existential philosophy suggest that acknowledging the scale of human influence in the Anthropocene can prompt a deeper sense of responsibility, rather than paralysis, if it is linked to collective action and solidarity.⁷

Ethical responses here include creating social spaces to talk honestly about climate fears, supporting communities directly affected by impacts, and framing climate work as a shared project that can give meaning and direction.⁶

The precautionary principle

The precautionary principle offers a guide for decision‑making under uncertainty, arguing that lack of full scientific certainty is not a reason to delay measures that could prevent serious or irreversible harm.⁶

In the climate context, this principle supports early and strong emissions cuts, as well as investment in adaptation, on the grounds that many tipping points and feedbacks are difficult to predict precisely in advance.⁶

International environmental agreements have incorporated precautionary language, reflecting a broad recognition that waiting for complete certainty about all climate impacts would risk locking in far more dangerous outcomes.¹⁰

Combined with justice‑based principles, precaution suggests that the most vulnerable communities and future generations should not be forced to shoulder the risks of continued high emissions and delayed action.⁵

Bringing the perspectives together

In practice, climate ethics rarely chooses a single principle but instead draws on several, balancing human‑centred concerns, ecological integrity, historic responsibility and future‑focused duties.¹⁰

Anthropocentric and ecocentric views may converge on strong climate action, even if they differ on whether the ultimate goal is protecting human wellbeing or safeguarding the living systems that make that wellbeing possible.¹

Climate justice frameworks push high‑emitting and wealthy actors to take the lead, while intergenerational ethics and precautionary reasoning argue against postponing decisions that would narrow the options of those who come next.²

These philosophical debates do not dictate one single policy path, but they clarify the values at stake and give citizens and governments a richer language for arguing about what counts as a fair response to a rapidly warming world.¹⁰
