Exposed: How Climate Risk in Australia Bypasses Community Sport - Lethal Heating Editor BDA




Key Points
  • Australia has warmed by 1.47°C since 1910, with extreme heat events becoming more frequent and severe, directly threatening participation in outdoor sport at every level.[1]
  • Tennis Australia and the AFL operate mandatory climate-risk protocols for elite competitions, but no equivalent enforceable standard covers community sport nationally.[3][4]
  • During the 2019–20 Black Summer, bushfire smoke drove Sydney’s air quality to hazardous levels during an international cricket Test, leaving unresolved questions about the duty of care owed to players who competed in those conditions.[6]
  • Children generate more metabolic heat per kilogram of body mass than adults and are less reliable at detecting early heat stress, placing them at the highest physiological risk during outdoor sport in extreme conditions.[8]
  • The 2022 south-east Queensland floods caused extensive damage to sporting infrastructure from Suncorp Stadium to community clubs across the river catchments, exposing critical gaps in insurance cover for volunteer-run organisations.[10]
  • CSIRO projections show that Australian alpine snow cover will decline significantly under all emissions scenarios, placing the domestic winter sports industry and elite training pathways under mounting long-term pressure.[12]

Australia's elite sporting bodies have built elaborate protocols for heat and air quality. On the community ovals, courts, and pitches where most Australians play, those protections largely stop at the gate.

The gap reflects the structure of Australian sporting governance. Regulatory authority concentrates at the elite level. Community sport operates on advisory frameworks that individual clubs, local councils, and volunteer associations can accept or disregard. 

As climate extremes intensify, that structure is producing a two-tier system of protection: careful and enforceable for professional athletes, advisory and patchwork for the millions of Australians who play sport each weekend.[2]

Australia has already warmed by 1.47 degrees Celsius since 1910, with the rate of increase accelerating since mid-century.[1]

Bureau of Meteorology records show extreme heat events are becoming more frequent and more severe across the continent. 

For outdoor sport, the consequences are direct and physiological: core body temperature rises faster under sustained aerobic load, cognitive function degrades under heat stress, and the risk of heat exhaustion climbs with each additional hour of exposure. 

Professional athletes train in facilities designed for climate adaptation. Community athletes compete on suburban and rural grounds where shade is scarce, cooling infrastructure is absent, and the nearest medical resource may be a volunteer with a first-aid certificate.

An Elaborate Architecture

Tennis Australia operates the most thoroughly documented extreme heat response framework in Australian sport. 

The policy, significantly revised after the 2014 Australian Open when temperatures at Melbourne Park reached 44 degrees and multiple players sought medical attention or withdrew from matches, uses a composite heat stress index drawing on wet bulb globe temperature, humidity, solar radiation, and wind speed as its primary indicators.[3]

When conditions at Melbourne Park reach specified thresholds, officials can close stadium roofs, restrict outdoor warm-ups, and suspend play on exposed courts. Decision-making authority rests with designated officials operating from calibrated monitoring data. Thresholds are published in advance. 

The system is imperfect, contested in its application, but documented and formally enforceable.

The AFL operates comparable protocols for elite fixtures, allowing match officials to pause or reschedule games when conditions present acute risk to player welfare.[4]

Both systems apply primarily to competitions the relevant bodies control directly. Below that level, the architecture dissolves.

Advisory, Not Mandatory

Sport Australia, the federal government’s peak sporting body, publishes hot weather guidelines for community sport. The guidelines recommend suspending activity when wet bulb globe temperature exceeds 28 degrees for high-intensity sport involving children, and 32 degrees for adult participation.[5]

Those thresholds align with international sports medicine consensus. They carry no legal force.

State sporting associations and local councils may adopt, adapt, or ignore the Sport Australia guidelines. The result across Australia is a fragmented collection of local policies, some rigorous, most informal, applied inconsistently by volunteer coaches and administrators who typically hold no formal training in heat physiology. 

When a junior football coach on a 41-degree February afternoon decides whether to cancel training, that decision occurs without legal compulsion, without calibrated monitoring equipment, and frequently without access to real-time wet bulb globe temperature data specific to the playing location.

Urban heat island effects in outer suburban areas, where community sport is densely concentrated, can push conditions several degrees above official Bureau of Meteorology readings taken at metropolitan weather stations. A coach consulting a weather app in western Sydney or Ipswich may be making a life-safety decision based on figures that understate conditions on the ground by four or five degrees.

Sport Australia holds no mechanism to enforce compliance with its guidelines. The legal question of whether sporting organisations can be held liable for harm to participants during foreseeable extreme weather events remains largely untested in Australian courts. 

As climate risk evidence accumulates, legal scholars have observed that the duty of care owed to sporting participants, particularly children, is likely to become substantially more defined.

When the Sky Turned Brown

The limits of sport’s climate governance became visible in January 2020, when smoke from the catastrophic Black Summer bushfires blanketed large parts of eastern Australia. 

Air quality in Sydney, Canberra, and Melbourne reached levels that public health authorities classified as hazardous for sensitive groups, with residents across those cities advised to minimise physical exertion and remain indoors where possible.[6]

The sporting response was inconsistent. A Women’s Big Bash League match in Canberra was abandoned when conditions became untenable. At the SCG, where Australia faced New Zealand in the third Test from January 3, 2020, play continued. Players warmed up on the outfield wearing face masks as smoke compressed the horizon and particulate readings climbed well above standard hazardous thresholds. Cricket Australia’s medical team monitored air quality index data in real time and the match proceeded.

The decision drew pointed and sustained criticism. Sports medicine professionals noted that athletes under aerobic competition load inhale substantially greater volumes of fine particulate matter than sedentary bystanders, with exercise-induced increases in ventilation rate multiplying the effective dose of pollutants absorbed into the airways.[7]

Cricket Australia subsequently developed more formal air quality protocols for its elite competitions, establishing threshold values and decision-making procedures that had not existed during the Black Summer. The review applied to events Cricket Australia controls directly. Community cricket clubs across New South Wales and Queensland, which had continued fielding matches through the same smoke events without any comparable policy framework, received no equivalent guidance update.

The Youngest Players

Children face a specific and underappreciated physiological risk in extreme heat. Sports medicine research has established that children generate more metabolic heat per kilogram of body mass than adults, dissipate that heat less efficiently through sweating, and are significantly less reliable at recognising and reporting the early symptoms of heat stress before they become serious.[8]

Children also acclimatise to heat more slowly than adults, requiring extended adjustment periods before sustained aerobic exercise in elevated temperatures becomes physiologically safe. Australian summer sport schedules are structured around school holiday availability rather than thermal safety. Saturday morning junior cricket and weekend football competitions take place across peak heat hours without any mandatory temperature ceiling that overrides local club decisions.

The Australian Institute of Sport has published guidance on heat acclimatisation that specifically identifies children’s elevated physiological vulnerability and recommends heightened caution during heat events involving young participants.[9]

That guidance sits in the same advisory category as the Sport Australia hot weather guidelines: carefully reasoned, well evidenced, and carrying no legal weight whatsoever.

The Cost Below the Surface

Climate risk in Australian sport extends well beyond player safety to the physical infrastructure on which sport depends. When south-east Queensland experienced catastrophic flooding in February and March 2022, the consequences for sporting infrastructure were extensive and largely invisible to national attention.

Suncorp Stadium in Brisbane required significant remediation work after surrounding precincts were inundated by floodwaters during the disaster event.[10]

Community clubs across the Ipswich and Brisbane River catchments lost playing surfaces, equipment stores, and change room facilities. Many carried insurance cover that proved inadequate for the scale of damage sustained. Those that attempted to renew their policies found insurers reassessing terms in light of demonstrated flood exposure. 

The Insurance Council of Australia has documented rising premiums and shrinking cover availability for community assets in flood and fire-exposed zones, a pattern that mirrors the residential insurance crisis accelerating in climate-vulnerable regions across the country.[11]

Regional clubs confront additional pressures that urban counterparts generally avoid. Prolonged drought conditions in inland eastern Australia have hardened playing surfaces on community cricket and football ovals to levels that exceed recognised safety benchmarks for player impact. Ground hardness above established thresholds increases the risk of impact injuries for fielders and can render pitch preparation unsafe. 

Water restrictions during drought periods make turf irrigation prohibitively expensive for volunteer-run clubs operating on annual budgets measured in tens of thousands of dollars.

The Retreat of Winter

Australia’s alpine region supports a winter sports industry centred on resorts at Mount Buller, Perisher, Thredbo, and Falls Creek. That industry, and the domestic training pathways it provides for Australian snow-sport athletes competing internationally, depends on natural snowfall that climate projections indicate is becoming progressively less reliable.

CSIRO research projects that alpine snow cover in Australia will decline under all emissions scenarios, with the largest reductions at lower elevations and during spring, shortening viable snow seasons from both ends of the calendar.[12]

Australian snow-sport athletes have in recent seasons increasingly sought training time at facilities in Europe, Japan, and North America to compensate for shorter and less predictable domestic conditions. The long-term question of national training infrastructure in an era of retreating snowpack has received little formal attention from winter sport governing bodies or federal sports policy. 

No published adaptation framework addresses the possibility that domestic snow seasons may eventually prove insufficient to support elite athletic development.

Commitments Without Compliance

Australia’s major sporting organisations have made visible commitments to reducing their own environmental footprints. Cricket Australia has published sustainability targets and committed to reaching net-zero emissions across its operations by 2030.[13]

The AFL has invested in renewable energy infrastructure at elite venues. Those commitments are substantive within the emissions reduction context, but they address sport’s contribution to climate change rather than its governance response to climate risk. The two objectives are distinct, and governing bodies have advanced the former considerably faster than the latter.

The legal terrain around duty of care in community sport is beginning to sharpen. Heat injuries in sport are not hypothetical. They are recorded, published in peer-reviewed literature, and directly attributable to participation in conditions that exceeded safe physiological thresholds.[14]

Courts have increasingly recognised that organisations exercising duty of care over participants cannot rely on informal frameworks when documented risks are foreseeable. Climate risk is now extensively and publicly documented. 

A serious heat injury to a child at a community sporting event, occurring in conditions that governing bodies had identified as dangerous in their own advisory guidelines while taking no steps to enforce compliance, would present a clear and uncomfortable liability question to any court examining the governance structure that permitted it.

Two Systems, One Climate

The architecture of Australian sporting governance has always concentrated resources at the elite end. Funding, regulatory attention, and policy development follow broadcast rights and media prominence. Climate governance has replicated that pattern with precision.

A professional tennis player at Melbourne Park competes under retractable roofs, monitored by a dedicated medical team, within a documented and enforceable heat policy framework. An eleven-year-old playing Saturday morning cricket in Penrith has none of those protections. The physiological science that describes the risks to both players is identical. The institutional response is not.

None of the governing bodies involved is acting recklessly. The AFL’s heat provisions for elite competition represent genuine investment in player welfare. Tennis Australia’s extreme heat framework embodies years of careful refinement. But investment in elite climate governance, unaccompanied by enforceable standards at the community level, produces a system that protects sport’s most visible assets while leaving its broadest participation base exposed to risks that are certain to intensify.

The summers getting longer do not distinguish between a Test match at the MCG and a junior football final in Wagga Wagga. 

The question is whether Australia’s sporting institutions will wait for serious harm, or a successful negligence claim, before building the protections that evidence has long recommended.

Winter’s Here, The Snowfields Are Open, But There’s No Snow - Gregory Andrews

Winter has arrived in Australia. At least, according to the calendar. The ski fields are open. The chairlifts are running. But even with the snow machines, there’s little or no snow to be seen. Warmth and rain have melted what little snow did fall, and the ski runs are mostly grass and mud.

At the same time, much of Australia has experienced its warmest start to winter on record. Sydney is on track for its warmest start to winter since records began in 1859. Melbourne and Canberra are experiencing their warmest starts to winter in decades. 

Across the country, temperatures are sitting well above average for this time of year. Sydney, Melbourne, Hobart and Canberra are all forecast to be at least 5 degrees warmer than average this week. In my garden, some of the spring flowers have already started blooming.

Globally, the picture is even more alarming. Climate scientist James Hansen and his colleagues argue that 2026 may be the hottest year ever recorded. Other researchers are more cautious, but there’s broad agreement on the underlying trend: global warming is not just occuring, its accelerating.

For years, climate change was something that happened elsewhere or in the future. It was melting glaciers in Greenland, droughts in Africa, coral bleaching on distant reefs, or record heatwaves in places we had never visited.

Now it’s here. It’s here when winter feels like early autumn. It’s here when our snow season arrives without snow. It’s here when insurance premiums rise, when food prices increase after climate-fuelled disasters, when extreme weather damages homes and infrastructure, and when ecosystems that have evolved over thousands of years struggle to adapt to changes occurring within decades.

Perhaps most concerning is how normal this is becoming. Humans are remarkably adaptable. We quickly become accustomed to new realities. 

Last year’s unprecedented temperatures become this year’s baseline. What would once have been front-page news becomes just another weather report at the bottom of a long list of other news.

This phenomenon has a name: shifting baseline syndrome. Each generation accepts the conditions it grows up with as normal, even when those conditions would have shocked previous generations. The danger isn’t simply that the climate is changing. The danger it’s that we stop noticing.

And while all this is happening, powerful interests would very much like us to be distracted.

They want us arguing about culture wars, symbolic controversies, and manufactured outrage. They want us fighting each other over identity, language, and social media scandals while the atmosphere continues to accumulate greenhouse gases and the planet continues to warm.

That’s not an accident. The fossil fuel fascists like culture wars because they divide communities, attract attention, generate clicks, and consume public debate. Every hour spent arguing over a manufactured controversy is an hour not spent discussing climate risk, energy transition, biodiversity loss, housing resilience, insurance affordability, or the long-term future of our children.

We mustn’t fall for it. Climate change doesn’t care how we vote. It doesn’t care whether we’re progressive or conservative, urban or regional, wealthy or struggling. Physics doesn’t negotiate. The atmosphere doesn’t respond to political spin. The snow doesn’t fall because a politician says everything’s OK and climate change is fake.

The challenge before us should not be ideological. The snowfields are open. But the snow is gone. If that doesn’t tell us something important about the future we are creating, I’m not sure what will.

Before getting despondent, check out my recent post on things you can do now to maintain active hope and help secure as safe planet.

Worried About Climate Collapse? Here’s Ten Things You Can Actually Do - Gregory Andrews

 Lyrebird Dreaming - Gregory Andrews


Author

Gregory Andrews is:

Someone asked a really good question on one of my posts recently. They said they loved the climate content but wondered what they can actually do. 

And honestly, that question matters. Because one of the worst things about climate collapse is the feeling of powerlessness. 

We watch governments approve new coal and gas. We watch billionaires and huge companies greenwash their way through everything. We watch floods, fires, heatwaves, bleaching, crop failures and insurance crises roll through communities - and then we’re told to recycle more.

Yes, personal choices matter. But they’re not enough. The climate crisis wasn’t created by ordinary people forgetting their reusable cups and shopping bags. It was created by political choices, corporate power, fossil fuel lobbying, and decades of delay. 

So the answer has to be bigger than individual guilt. It has to be about active hope. Not passive optimism. That means choosing to act because the future is still being shaped, and because power shifts when people organise.

Here’s my top ten things you can do.

1. Stop trying to do everything

This might sound strange as number one. But it matters. Climate collapse is overwhelming because it touches everything: energy, transport, housing, food, forests, oceans, politics, money, war, migration, health and justice. Nobody can work on all of that at once. So choose your lane.

Maybe your thing is political campaigning. Maybe it’s protecting a local forest. Maybe it’s helping renters electrify. Maybe it’s First Nations justice. Maybe it’s calling out fossil fuel fascism. Maybe it’s making art, writing posts, showing up at meetings, or helping good people get elected. 

You don’t have to do everything. But you do need to do something.

2. Join with other people

Individual action matters most when it becomes collective action. One person writing to a politician can be ignored. A thousand people writing to a politician becomes a problem. One person changing banks is symbolic. Thousands of people shifting their money away from fossil fuel finance becomes pressure. One person talking about climate might feel isolated. A community talking about climate can change an election.

This is why movements matter. Find a local climate group, a community campaign, a Landcare group, a union campaign, a school group, a renewable energy group, or a community independent campaign. 

Climate action becomes less scary when you stop carrying it alone.

3. Get political - properly political

The climate crisis isn’t just an environmental issue. It’s a political issue. That means voting matters. But voting isn’t the only thing that matters. Join campaigns. Door knock. Hand out how-to-vote cards. Scrutineer. Host kitchen table conversations. Ask candidates direct questions. Support people who are serious about climate, integrity and community.

I felt genuinely empowered working with my community to help get David Pocock elected in 2022. It reminded me that politics doesn’t have to be something done to us by party machines. It can be something we do together. And we almost got there with Jessie Price in 2025. Next time, for sure. The community independents movement matters because it shows that ordinary people can organise, challenge the major parties, and change the national conversation. 

That’s climate action.

4. Hold politicians accountable between elections

Politicians don’t only need to hear from us every three years. They need to hear from us all the time. Email them. Call their offices. Ask for meetings. Turn up to town halls. Respond to consultations. Make submissions. Ask simple, direct questions:

  • Will you support no new coal and gas?
  • Will you support a climate trigger in national environment law?
  • Will you support ending fossil fuel subsidies?
  • Will you support protecting forests?
  • Will you support electrifying homes, transport and industry?

Don’t let them hide behind vague language about “balance”, “transition” or “all of the above”. Ask what they’re actually doing.

5. Follow the money

The fossil fuel industry does’t just dig up coal and gas. It buys influence. It sponsors events. It funds think tanks. It donates to political parties. It advertises during sporting events. It puts its logo on community programs. It hires lobbyists. It uses greenwashing to buy social licence. So follow the money.

Ask who’s funding the campaign. Ask which companies are sponsoring the conference. Ask whether your superannuation is invested in fossil fuels. Ask whether your bank is lending to new coal and gas projects. Ask whether your university, sporting club, festival, arts organisation or charity is taking fossil fuel money. 

The social licence of fossil fuel companies is not inevitable. It can be withdrawn.

6. Call out fossil fuel fascism and corporate greenwashing

Big fossil fuel companies aren’t just selling coal and gas. They’re defending a dying business model with political donations, lobbying, disinformation, culture wars, attacks on protest rights, and greenwashing. That’s why I call it fossil fuel fascism. It’s what happens when a powerful industry knows its product is destabilising the climate, but instead of changing course, it tries to bend democracy around its own survival.

So call it out. When a gas company says gas is “clean”, ask compared to what. When a coal company sponsors a community event, ask what social licence it’s trying to buy. When politicians repeat fossil fuel talking points, ask who benefits. When corporations talk about “net zero”, ask whether they’re still expanding coal and gas. When media outlets run climate denial or delay narratives, ask who’s funding the story.

Greenwashing works when nobody challenges it. Fossil fuel power works when people are too polite, too tired, or too intimidated to name it. Name it. Because democracy can’t survive if governments keep serving fossil fuel companies while communities pay the price.

7. Use your workplace, profession and networks

Most of us have more influence than we realise. You may not feel powerful as one person. But you may be part of a workplace, board, school, university, union, church, sporting club, professional association, arts organisation or community group.

Ask what your organisation is doing on climate. Does it have a climate policy? Is it electrifying? Is it divesting? Is it reducing travel emissions? Is it still banking with fossil fuel lenders? Is it purchasing renewable energy? Is it using its public voice? 

Every institution is part of the climate system now. Push yours.

8. Protect nature where you live

Climate and nature aren’t separate crises. Protecting forests, wetlands, grasslands, rivers, reefs, soils and threatened species is climate action. So is restoring habitat, removing invasive species, supporting cultural burning, protecting urban trees, and defending Country from destructive development.

This work is local, practical and powerful. It also helps to counter despair. Because when you plant something, restore something, defend something, or care for Country, you’re not just opposing destruction. 

You are participating in repair. That matters.

9. Talk about climate in human terms

Facts matter. Science matters. Data matters. UN treaty obligations matter. But people are moved by stories. So talk about climate as a cost-of-living issue. Talk about insurance. Talk about rent and food prices. Talk about asthma. Talk about heat stress. Talk about children. Talk about older people. Talk about farmers, our Pacific neighbours and First Nations communities watching Country change before their eyes.

The climate crisis isn’t a future abstraction. It’s already here. And it’s already personal.

The more we make that visible, the harder it becomes for politicians and corporations to pretend delay is harmless.

10. Practise active hope

Hope isn’t the belief that everything will be fine. Hope is the decision to act anyway.

Some days, that might mean joining a campaign. Some days, it might mean making a phone call. Some days, it might mean donating $20. Some days, it might mean sharing a post. Some days, it might mean resting so you can keep going.

Climate action isn’t about purity. It is about persistence. The fossil fuel industry and fascists want us isolated, exhausted, cynical and ashamed. So refuse that.

Find your people. Choose your lane. Build power. Hold politicians accountable. Hold companies accountable. Protect what you love. And keep going. Because the future isn’t decided yet. And ordinary people like us, organised together, have changed history before.

Australia: When the Thermometers Come Under Pressure - Lethal Heating Editor BDA

Australia's climate intelligence system faces growing strain
as the continent records unprecedented heat
Key Points
  • Australia has warmed by about 1.5°C since 1910.[1]
  • Extreme heat is Australia's deadliest natural hazard.[2]
  • Climate risks increasingly cascade across multiple systems.[3]
  • Marine heatwaves are growing in frequency and intensity.[4]
  • Urban areas face rising exposure to extreme heat.[5]
  • Climate science capacity faces ongoing institutional pressures.[6]
The Instruments in the Heat

The temperature display outside Bourke climbed through the forties before midday.

Across inland Australia, automated weather stations stood in the glare, collecting measurements that would flow through telecommunications networks, forecasting systems, climate archives, emergency management centres, and research institutions.

Each reading appeared routine. Together they formed the nervous system of a continent confronting accelerating climate change.

Australia has warmed by approximately 1.5°C since national records began in 1910, according to Bureau of Meteorology and CSIRO assessments. The country's ten warmest years have all occurred since 2005. [1]

Those numbers underpin decisions worth billions of dollars. Farmers use them. Energy operators depend upon them. Emergency services rely on them during heatwaves, bushfires, floods, and cyclones.

Few Australians ever see the infrastructure producing those measurements.

Watching a Continent Grow Hotter

The Bureau of Meteorology operates one of the largest environmental monitoring networks in the Southern Hemisphere.

Weather stations stretch across deserts, tropical coastlines, alpine regions, airports, islands, and remote communities. Ocean buoys track conditions offshore. Satellites relay information from regions where few people live.

The system was built for a different climate.

Australia's climate statement for 2024 recorded the nation's second-warmest year since records began. Heatwave conditions affected large parts of the country throughout the year, while minimum temperatures reached record levels nationally. [7]

Long-term warming creates a paradox for climate monitoring.

The hotter Australia becomes, the more heavily governments, businesses, and communities depend upon accurate observations. Yet the same rising temperatures increase stress on infrastructure, communications systems, ecosystems, and critical services.

Climate monitoring has become both a witness and a participant in the climate story.

The Human Stakes Behind the Data

Heat rarely arrives with the dramatic imagery of a cyclone.

It creeps through suburbs after sunset. It lingers inside ageing homes. It settles over regional towns where air conditioning becomes a necessity rather than a luxury.

The consequences often appear in hospital admissions, ambulance call-outs, and excess mortality statistics.

Research and government assessments consistently identify extreme heat as Australia's deadliest natural hazard. Recent studies suggest the human toll associated with heatwaves greatly exceeds figures captured through direct heat-related death classifications alone. [2]

Older Australians, people with chronic illnesses, outdoor workers, and residents of lower-income communities face particularly high exposure.

In western Sydney, summer temperatures can differ dramatically from cooler, leafier suburbs closer to the coast.

The thermometer records a number. The social consequences depend upon where people live, work, and sleep.

The Great Barrier Reef and the Silent Ocean Emergency

Hundreds of kilometres offshore, another monitoring challenge unfolds.

Marine heatwaves increasingly reshape ecosystems that once changed slowly across decades.

Coral reefs, fisheries, seagrass systems, and coastal habitats depend upon long-term observations capable of detecting subtle trends before they become irreversible transformations.

The State of the Climate 2024 assessment found marine heatwaves around Australia are becoming more frequent and more intense as ocean temperatures rise. Australian waters have warmed by more than one degree since 1900. [4]

Scientists monitoring the Great Barrier Reef increasingly rely on integrated observing systems combining field measurements, satellites, ocean sensors, and modelling.

Those datasets allow researchers to distinguish temporary fluctuations from structural ecological change.

Without continuous observations, ecological decline becomes harder to detect until consequences become visible across entire ecosystems.

A Network Under Institutional Pressure

Climate observations depend upon people as much as instruments.

Technicians maintain equipment. Scientists validate records. Analysts examine anomalies. Software specialists manage data flows measured in millions of observations.

Institutional capacity often receives less attention than climate statistics.

Recent debate surrounding climate science staffing highlights how specialised expertise can become concentrated within relatively small teams. Scientists have warned that reductions in climate modelling capability could affect Australia's contribution to future international climate assessments and national projection systems. [6]

Such concerns extend beyond individual agencies.

Climate adaptation planning, infrastructure investment, insurance pricing, agricultural forecasting, and emergency management increasingly depend upon sophisticated climate intelligence.

Every observing network ultimately relies upon sustained funding, institutional memory, and scientific expertise.

Cascading Risks

Climate hazards rarely remain confined to a single sector.

A severe heatwave can impact public health, electricity demand, transport infrastructure, agricultural productivity, and ecosystem stability simultaneously.

Australia's first National Climate Risk Assessment places particular emphasis on these interconnected risks.

The assessment identifies climate impacts as cascading, compounding, and concurrent, affecting infrastructure, health, food systems, ecosystems, and economic activity at the same time. It highlights dozens of nationally significant climate risks across Australian society. [3]

Climate monitoring provides one of the few mechanisms capable of tracking those interactions across multiple systems.

Temperature records connect to hospital admissions.

Ocean observations connect to fisheries.

Rainfall measurements connect to water security and agricultural production.

Data becomes the bridge linking physical change to social consequence.

The Cities Heating from Within

More than ninety per cent of Australians live in urban areas.

Many cities create their own microclimates through roads, concrete, roofing materials, reduced vegetation, and dense development.

Urban heat can amplify already dangerous temperatures.

Researchers examining Australia's urban climate capability argue that significant gaps remain in observational networks and datasets needed to understand city-scale climate risks. Those gaps can alter adaptation planning and heat resilience strategies. [5]

The challenge carries immediate implications.

Local governments need accurate information when deciding where to plant trees, upgrade public housing, design cooling centres, or protect vulnerable populations during prolonged heatwaves.

Every adaptation strategy begins with measurement.

The Future of Climate Intelligence

The most important climate story in Australia may involve neither emissions nor forecasts.

It may involve observation itself.

Every year brings higher temperatures, more intense marine heatwaves, growing infrastructure exposure, and increasing pressure on institutions responsible for understanding those changes.

The World Meteorological Organization emphasises that climate services and early-warning systems are becoming increasingly vital as global temperatures continue rising. [8]

Australia's climate monitoring network represents far more than thermometers in paddocks or buoys floating offshore.

It functions as a national intelligence system for a warming continent.

The decisions Australians make about cities, food production, public health, insurance, infrastructure, and ecosystems will depend upon the quality of information flowing through that system.

As climate risks become more frequent and more interconnected, the value of trustworthy observations rises alongside the temperature.

The future may judge climate monitoring as one of the country's most important forms of adaptation, a quiet infrastructure of measurement helping Australians understand a world changing faster than the institutions built to measure it.

The world’s hottest years over the past decade have coincided with stagnant economic productivity, rising prices and geopolitical instability.

Is this just coincidence or has the current level of climate change been one of the drivers? Climate change is often framed as a problem for the future. But how much economic damage has today’s current level of ~1.35°C of warming already caused?

To answer that question, we analysed the effects of climate change to date on the New South Wales economy. The results were released today as part of a Net Zero Commission report.

We estimate climate change has already caused median losses of around 18% (probability range 4–33%) to the NSW economy, the biggest economic jurisdiction in the country. At a median 18% loss, that translates to about A$21,300 per person on average in yearly income.

We show that it’s not local bushfires or flooding that are driving the majority of damage, but changing global weather that in turn affects our cost of living.

Imagine a world without climate change

Studies typically project the global economic damage that climate change will do by 2050 or 2100.

Some influential estimates have suggested climate damage would be fairly small. But our recent research and work by others shows the economic damage coming down the pipeline could be more than four times larger than previously thought.

Our research question for this report was different: “What would the NSW economy look like today if historical emissions of greenhouse gases had not caused climate change?”

This requires a thought experiment: imagining a past where we burn fossil fuels at the historical rate, but the additional carbon dioxide and other atmospheric gases do not cause changes to temperature or rainfall patterns.

Answering this question will allow us to understand the economic losses we have already endured from historical climate change.

How we did it

First, we collected data on historical economic growth and weather across the world over the past 70 years. We then modelled how weather changes (or shocks) impacted economic growth over this period. There is significant debate on how to do this, so we adopted a variety of approaches. 

Then we had to plausibly guess at how the weather would have evolved in the past four decades without climate change. To create this hypothetical weather series, we simply removed any trend found in the weather data which we ascribe to human-caused climate change. This works because there is no evidence natural causes have contributed to the upward trend in temperatures.

 Finally, we compared economic growth rates predicted by the models under the observed and under the hypothetical weather conditions. The contrast between the total economic production of the NSW economy in the two scenarios is the economic cost of historical climate change for a given year.

What we found

We estimate the median economic loss for NSW in 2024 was 18%. There is significant uncertainty in this figure, with the lower estimates around 4% and the higher around 33%.

The median loss figure of 18% translates into an average of $21,288 in losses per person in yearly income (in 2023–2024 dollar values). In other words, the model finds that if historical warming had not occurred then people living in NSW would each have $21,288 more dollars, on average, in their pockets every year. This amount is large enough to meaningfully improve the quality of life of the state’s average household.

The models suggest the primary mechanism through which this loss has occurred is the rise in the global average temperature. When people think about losses associated with climate change in NSW, they might consider how climate change exacerbated the bushfires of 2019–20, or the floods that followed. The damages they caused are, of course, real and significant.

However, the economic models suggest the majority of the damage has come from shifts in weather globally. Given the interconnectedness of modern economies through trade and global supply chains, it is reasonable to assume that climate shocks to supply chains affect the whole globe.

The interconnectedness of the global economy can be seen in the downturn following the US-Israel war with Iran and the halt to shipping in the Strait of Hormuz. Eric Seddon/Pexels, CC BY
How we think about climate change

When pollsters ask Australian voters what issues they care about, “climate change” is often listed as one issue among many. Voters are asked to assess how important climate change is to them relative to the cost of living, public health, interest rates, secure employment, and other important things.

Presenting issues in this way reinforces a common misconception that they are independent, and that one can be prioritised over the other.

To the contrary, there is now good evidence that climate change is strongly related to economic outcomes, which in turn drive the cost of living, interest rates, investment in in health and education and the labour market.

It’s time to stop thinking of climate change as “merely” an environmental issue, which can be discarded when economic times are tough. Instead, we should recognise what it really is: a current and ongoing threat to our standard of living.
