Q&A: How are Aboriginal and Torres Strait Islander communities being disproportionately affected by climate extremes? - Lethal Heating Editor BDA

Key Points Remote First Nations communities face intensifying climate extremes Heatwaves and droughts are stressing housing, health, and water access Sea level rise threatens Torres Strait Islands with inundation Cultural practices are disrupted by ecosystem change and fire regimes Calls grow for climate justice and Indigenous-led adaptation

Aboriginal and Torres Strait Islander peoples are on the frontlines of climate change, enduring intensifying extremes with fewer resources and deeper historical wounds.

Across northern Australia and the Torres Strait, Indigenous communities are experiencing the compounding effects of global heating at alarming rates.

Inland towns like Wilcannia and remote desert settlements face frequent heatwaves exceeding 45°C, while clean drinking water supplies dry up and local infrastructure strains under pressure.¹

For Torres Strait Islander communities, sea-level rise is not a future threat, it’s a present emergency.

Low-lying islands such as Boigu and Saibai are seeing homes, graves, and sacred sites inundated with saltwater, causing erosion and salinisation that threatens habitability.²

The Heat Inequality

Many Aboriginal households in central and northern Australia are poorly insulated, overcrowded, and reliant on aging power infrastructure.

These conditions intensify health risks during prolonged heatwaves, especially for elders and people with chronic illness.

In some regions, power outages due to overburdened grids leave families without cooling during deadly summer spikes.³

Without urgent upgrades to housing, energy security, and community health, these compounding stresses are likely to worsen.

Water Crisis and Climate Stress

Aboriginal communities in arid zones depend on bore water, creeks, and rainfall tanks, resources being stressed by hotter, drier conditions.

In Western NSW, residents of Walgett have endured drinking water sourced from highly saline bores during droughts, raising serious health concerns.⁴

In the Kimberley, flash floods damage roads and isolate settlements for weeks, blocking supply chains and emergency access.

Culture, Country, and Displacement

Connection to Country is central to Aboriginal and Torres Strait Islander culture, health, and identity.

But climate change is altering seasonal patterns, plant growth, animal migration, and fire behaviour, severing knowledge systems honed over millennia.⁵

In the Torres Strait, residents fear becoming Australia’s first climate refugees, facing relocation with no clear national plan.

Calls for Justice and Leadership

First Nations leaders are calling for climate justice that recognises their disproportionate vulnerability, the legacy of colonisation, and their right to lead solutions.

In 2022, eight Torres Strait Islanders lodged a human rights complaint with the UN, accusing the Australian government of failing to protect their islands.⁶

Climate adaptation led by Indigenous knowledge, such as firestick farming, sustainable water governance, and place-based resilience, offers critical pathways for the nation.

But without robust policy, funding, and constitutional recognition, those solutions risk being sidelined.

The Road Ahead

As climate extremes escalate, protecting First Nations communities must become a national priority.

That means listening to Aboriginal and Torres Strait Islander voices, supporting self-determination, and embedding their leadership at every level of the climate response.

Because those most affected by climate change should never be the last to be heard.

Q&A: How has Australia’s average temperature changed over the past century? - Lethal Heating Editor BDA

Key Points Australia has warmed by 1.5°C since 1910 Seven of the ten warmest years have occurred since 2013 Minimum temperatures rising faster than maximums Climate change signals now outweigh natural variation Warming linked to extreme weather and bushfires

Australia has warmed faster than the global average, with widespread impacts now visible in every State and Territory.

The Bureau of Meteorology reports that Australia’s average surface temperature has risen by about 1.5°C since 1910¹.

This warming has accelerated in recent decades, with the last ten years ranking among the hottest ever recorded.

Australia’s seven warmest years on record have all occurred since 2013, and 2019 was the hottest year ever documented².

Historical Climate Records

Australia's instrumental temperature record began in 1910, providing a robust century-long dataset.

Analysis shows a steady upward trend, particularly since the 1970s.

The increase in average temperature is most pronounced in the interior and northwest regions of the country, but even cooler coastal zones have warmed significantly³.

Minimum vs Maximum Temperatures

Interestingly, minimum (night-time) temperatures have increased faster than maximum (day-time) temperatures.

This is consistent with global patterns and suggests long-term shifts in atmospheric and land-surface heat retention.

Warmer nights mean less relief from heatwaves, with serious implications for human health, energy demand, and agriculture⁴.

Attribution to Human Activity

Scientists attribute most of this warming to increased concentrations of greenhouse gases from human activity.

The influence of natural climate variability (such as El Niño and La Niña) is now outweighed by anthropogenic signals in temperature data⁵.

Australia’s per capita emissions remain among the highest in the world, contributing to the problem at home and globally.

Impacts and Consequences

The consequences of warming are already being felt.

More frequent and intense heatwaves, longer bushfire seasons, coral bleaching, and declining snow cover are all linked to the rising national average temperature⁶.

For example, the devastating 2019–2020 bushfires were made significantly more likely by climate change-induced heat and drought⁷.

Looking Ahead

If global warming continues unabated, Australia could warm by another 2–4°C by the end of the century.

This would radically alter ecosystems, agriculture, coastal settlements, and the health of communities across the country.

Limiting warming to 1.5°C globally, as per the Paris Agreement, would require deep, immediate cuts in greenhouse gas emissions.

Australia’s warming story is a warning — and a call to action.

Which Parts of Australia are Warming the Fastest and Why - Lethal Heating Editor BDA

Key Points Central and northwestern Australia are heating fastest Cities are warming due to urban heat islands Rainfall changes, land cover, and geography amplify warming Indigenous communities and wildlife are most exposed

Australia's climate is warming fast but not evenly.

Some regions are heating at almost twice the national average, triggering wide-ranging consequences for people, ecosystems, and industries.

Warming Hotspots in the Heart of the Continent

The fastest warming areas in Australia are inland regions of Western Australia, the Northern Territory, and Queensland.

In particular, the Pilbara and central Northern Territory have recorded temperature increases of more than 1.5°C since 1950, well above the national average of 1.4°C^[1].

These regions tend to be arid or semi-arid, which means they have less cloud cover and vegetation to absorb solar radiation.

Less moisture in the soil means more of the sun’s energy heats the land surface directly.

Why the Outback Is Getting Hotter

Multiple factors contribute to the rapid heating of inland Australia.

Dry soils, land clearing, and loss of native vegetation reduce evaporative cooling, accelerating the surface warming process^[2].

Rainfall has also declined across many inland zones, reinforcing the drying-heating feedback loop.

With less vegetation and fewer wetlands, the land reflects less energy back into the atmosphere, leading to further warming.

Cities Are Heating Differently

Urban areas like Sydney, Melbourne, and Brisbane are warming at a different pace, partly due to the urban heat island effect.

Concrete and asphalt surfaces retain heat, and population growth adds emissions and energy usage, intensifying city warming^[3].

In coastal areas, sea breezes and higher humidity slow down the rate of heating slightly compared to inland cities like Alice Springs.

Who’s Most at Risk?

Rural and remote Indigenous communities often live in the areas most exposed to heat extremes and have fewer resources for adaptation^[4].

Wildlife in central Australia, like the bilby and the central rock-rat, are also struggling to adapt to rapid environmental shifts.

Warming hotspots are pushing ecosystems toward critical tipping points, with cascading effects on biodiversity, food systems, and health.

What It Means for the Future

Understanding where Australia is warming fastest is essential for targeting adaptation strategies and protecting vulnerable populations.

Without rapid emission cuts and targeted resilience planning, large parts of the country may become increasingly uninhabitable during summer.

Inland Australia will likely remain a focal point of climate stress, even if national warming trends begin to stabilise.

The heat is rising and in Australia’s vast interior, it’s rising faster than anywhere else.

On the Brink: Australia’s Looming Climate Tipping Points - Lethal Heating Editor BDA

Key Points Australia faces multiple climate tipping points Coral bleaching threatens Great Barrier Reef Collapse of carbon-rich ecosystems is accelerating Bushfire feedback loop may already be active Risk of desert expansion in southeast and southwest

Australia is approaching dangerous climate tipping points that could push ecosystems past the point of recovery.

Scientists are warning that several critical climate systems in Australia are nearing collapse, or have already begun shifting irreversibly.

Tipping points are thresholds beyond which environmental change accelerates, becomes self-sustaining, and cannot be reversed by cutting emissions alone.

For Australia, a continent marked by climatic extremes, fragile ecosystems, and large carbon sinks, the risks are especially high.

The Great Barrier Reef: A Coral Graveyard in Waiting

One of the most visible, and urgent, tipping points is the degradation of the Great Barrier Reef^[1].

Marine heatwaves have triggered five mass bleaching events since 2016, weakening coral resilience and killing more than 50% of shallow-water coral cover in parts of the reef.

According to the IPCC, if global warming reaches 1.5°C, over 90% of the world’s coral reefs will likely disappear. At 2°C, virtually all are lost.

This collapse would devastate biodiversity and destroy an ecosystem that supports 64,000 Australian jobs.

Bushfires and the Forest-Climate Feedback Loop

Forests in southeastern Australia, including the fire-sensitive alpine ash and mountain ash ecosystems—are experiencing dieback due to hotter, drier conditions and more frequent fires.

The 2019–2020 Black Summer^[2] burned more than 24 million hectares and released 900 million tonnes of CO₂—nearly twice Australia’s annual emissions.

These emissions feed back into the climate system, increasing warming and fire risk. Scientists fear this self-reinforcing cycle is a major regional tipping point already underway.

Rainforests Under Stress: From Moist to Dry

In far north Queensland and Tasmania, rainforests once considered fire-proof are becoming increasingly flammable due to prolonged dry spells.

Once these ecosystems cross a threshold of desiccation and fire disturbance, their structure and function can shift permanently toward open woodlands or savannahs, resulting in reduced carbon storage and biodiversity loss.

The Climate Council^[3] notes that this transition is already underway in parts of the Daintree and Gondwanan rainforests.

Desertification in the South

Southern Australia’s Mediterranean zones, particularly parts of South Australia, Victoria, and southwest Western Australia, are drying faster than almost any other region in the Southern Hemisphere.

Declining winter rainfall and overuse of groundwater are pushing these regions toward a dryland tipping point.

Once vegetation cover collapses, soils degrade irreversibly, leading to expanding deserts and dust bowl conditions.

The Vanishing Carbon Sinks

Australia’s forests, mangroves, and seagrass meadows store vast quantities of carbon, but their ability to sequester CO₂ is being undermined.

Heatwaves, sea level rise, and fire-driven degradation reduce their carbon-capturing function, risking a net shift from sink to source.

This has global implications: if key Australian carbon stores collapse, the world loses critical buffers against climate breakdown.

Crossing the Line

Tipping points are not predictions.

They are warnings. They signal that some changes, once triggered, cannot be undone within human timescales.

Australian scientists urge rapid emissions reductions, landscape-scale restoration, and protection of remaining intact ecosystems as the only path to minimise irreversible loss.

Without immediate action, Australia could become both a victim and driver of global climate instability.

Australia’s Climate Update: Emissions, Heat, and Policy in 2025 - Lethal Heating Editor BDA

Key Points 2025 brings hottest winter on record Australia faces rising climate lawsuits Federal Government accused of emissions backslide Insurance crisis escalates in heat-prone areas Climate-linked migration pressure intensifies

Australia is confronting a series of extreme climate disruptions in 2025 as warming accelerates and public trust in federal climate policy frays.

Across the country, temperatures have soared to unprecedented highs even in winter, with national records smashed during what should be the year’s coldest months. ^[1]

This July marked the hottest winter start in Australia’s recorded history. ^[2]

Heatwaves pushed maximum temperatures beyond 35 °C in parts of Western Australia and the Northern Territory. ^[3]

“We’re witnessing the destabilisation of traditional seasonal boundaries,” said Dr. Sarah Perkins-Kirkpatrick, a climate scientist at the University of NSW. ^[4]

The Bureau of Meteorology linked the phenomenon to a record-breaking marine heatwave and underlying warming trends that have lifted Australia's average temperature 1.47 °C above pre-industrial levels. ^[5]

Government Emissions Policy Under Fire

Despite committing to net-zero emissions by 2050, the Albanese government is under scrutiny for approving new fossil fuel projects. ^[6]

Two large-scale gas developments—the Beetaloo Basin in the NT and the Scarborough project off WA—received federal backing earlier this year. ^[7]

Climate advocacy groups say these approvals are inconsistent with the Paris Agreement and threaten to undo emissions progress under the Safeguard Mechanism reforms. ^[8]

The government counters that domestic gas supply is essential to energy security, but critics argue the country is fuelling export-driven emissions rather than transitioning away from fossil fuels. ^[9]

Legal and Economic Pressures Escalate

Climate litigation is also ramping up. ^[10]

The Environmental Defenders Office (EDO) launched legal action against the Environment Minister in June, arguing that the approval of coal expansion at the Mount Pleasant mine ignored climate risks to human rights and the Great Barrier Reef. ^[11]

Meanwhile, insurance premiums have skyrocketed across flood- and fire-prone regions, with some northern Queensland homeowners facing policy cancellations altogether. ^[12]

The Insurance Council of Australia warned that the sector is under “existential stress” as extreme weather events become more frequent and less predictable. ^[13]

Pacific Displacement and Migration Impacts

Rising sea levels and worsening cyclones in the Pacific have pushed Australia to consider a more structured “climate migration” policy. ^[14]

Tuvalu and Kiribati are among the nations pressing for pathways that would allow for managed relocation, education access, and permanent residency. ^[15]

Australia’s Department of Home Affairs is reportedly assessing a climate visa pilot, but no formal announcement has been made. ^[16]

Observers say delays risk reputational damage in the region and could undermine Australia’s climate diplomacy ahead of COP30 in Brazil. ^[17]

Political Risks Mount

With national elections on the horizon, climate policy remains a major electoral battleground. ^[18]

Opposition Leader Peter Dutton has doubled down on nuclear energy as an alternative to the government’s renewables-led strategy, despite cost and timeline uncertainties. ^[19]

Younger voters, increasingly concerned about climate inaction, have fuelled Green and independent momentum in urban electorates. ^[20]

In a year defined by global heat, sea-level rise, and shifting climate politics, Australia stands at a crossroads between rhetoric and real reform. ^[21]

World Court Declares Climate Change an Existential Threat - Lethal Heating Editor BDA

Key Points   ICJ warns of global legal obligations on climate Greenhouse gases deemed human-caused and urgent Small island states hailed ruling as historic Industrialised nations expected to lead Ruling may shape future litigation, treaties Paris Agreement’s 1.5°C goal reaffirmed

The United Nations' highest court has declared that nations must act to curb greenhouse gas emissions or risk violating international law.

In a sweeping advisory opinion issued this week, the International Court of Justice (ICJ) ruled that climate change constitutes an “existential threat” to humanity and underscored that nations, especially industrialised ones, have binding legal responsibilities to prevent further global warming.¹

The opinion, though non-binding, represents the most powerful legal statement yet on the global climate emergency.² 

The court’s declaration comes as climate-induced disasters, from deadly floods in China to record-setting heatwaves across Europe and North America, highlight the mounting toll of inaction.

“States have an obligation to take all necessary measures to ensure that activities within their jurisdiction do not cause harm to the climate system,” the opinion stated.¹

Landmark Case Led by Island Nations

The ruling followed a 2023 request brought by the United Nations General Assembly and championed by Vanuatu and other small island developing states (SIDS), whose very existence is threatened by rising sea levels and intensifying weather patterns.⁴

“This is a legal and moral victory,” said Ralph Regenvanu, Vanuatu’s Climate Minister. “The Court has confirmed that the world’s most vulnerable are entitled to protection, and that major polluters must act.”⁴

The ICJ concluded that greenhouse gas emissions are “unequivocally caused by human activities” and stressed that failure to mitigate emissions, adapt to climate change, or support vulnerable countries could breach international law.¹

Legal Force with Global Implications

Though advisory opinions from the ICJ are not enforceable, they are authoritative interpretations of international law and often influence global treaties, domestic court rulings, and multilateral negotiations.³ 

Experts say the ruling could galvanise legal action by climate-vulnerable nations, especially in pursuing compensation or demanding policy changes from major emitters.

“This is a legal tsunami,” said Payam Akhavan, international law professor at the University of Toronto and counsel for the Pacific Island nations. “It affirms that climate inaction has consequences under law—not just politics.”⁴

The Court’s opinion is expected to bolster similar cases in regional and national courts, including ongoing legal actions in Europe, South America, and Africa, where plaintiffs argue that climate inaction violates rights to life, health, and culture.⁵

Responsibility of Major Emitters

The ICJ made clear that responsibility for preventing climate harm falls disproportionately on nations with the greatest historical emissions. That includes the United States, China, the European Union, and other high-income economies.²

The Court cited the Paris Agreement’s goal to limit global warming to 1.5 °C, warning that every additional increment of temperature rise deepens human suffering and environmental loss.¹

“The ruling affirms what science has long made clear: rich nations must lead in decarbonising, financially supporting poorer states, and advancing loss and damage frameworks,” said María Fernanda Espinosa, former UN General Assembly President.⁴

Political Pressure Ahead of COP30

The ruling adds momentum to global pressure on governments to deliver ambitious climate action ahead of the COP30 summit in Belém, Brazil, this November. 

Many countries have yet to update their Nationally Determined Contributions (NDCs), which outline emission reduction targets under the Paris framework.³

For climate activists and vulnerable nations, the ICJ opinion is not just a call to conscience—it is a call to legal duty.²

“This judgment transforms the climate crisis from a policy preference into a matter of global justice,” said Shyla Raghav of the nonprofit Climate Justice Now. “There can be no more excuses.”²

Legal Era of Climate Accountability

The ruling comes as climate litigation surges globally. Over 2,500 lawsuits have now been filed across 60 jurisdictions, targeting fossil fuel companies, governments, and banks that fund polluting infrastructure.⁵

As world leaders prepare for the next phase of negotiations, legal scholars warn that the era of voluntary promises may be ending. The ICJ’s decision sets the stage for a new paradigm where legal accountability drives climate ambition.³

In the words of one ICJ judge, “The future of the planet cannot be left to political discretion. It is a matter of law.”¹

Only 3 years left – new study warns the world is running out of time to avoid the worst impacts of climate change

The Conversation - Piers Forster  Debbie Rosen

Piyaset/Shutterstock

Authors Piers Forster is Professor of Physical Climate Change; Director of the Priestley International Centre for Climate, University of Leeds Debbie Rosen is Research and Innovation Development Manager for the Priestley Centre for Climate Futures, University of Leeds Key Points Only 25 countries have submitted updated climate plans Human-caused warming hit 1.36°C in 2024 The world reached an average of 1.52°C warming The remaining carbon budget could be gone in 3 years Just 10 countries plan to phase out fossil fuels G20 accounts for 80% of global emissions

Bad climate news is everywhere.

Africa is being hit particularly hard by climate change and extreme weather, impacting lives and livelihoods.

We are living in a world that is warming at the fastest rate since records began.

Yet, governments have been slow to act.

The annual global climate change conference of the parties (COP30) is just months away.

All of the 197 countries that belong to the United Nations were supposed to have submitted updated national climate plans to the UN by February this year.

These plans outline how each country will cut its greenhouse gas emissions in line with the legally binding international Paris Agreement.

This agreement commits all signatories to limiting human-caused global warming to no more than 1.5°C above pre-industrial levels.

Governments must also bring their newly updated national climate action plans to COP30 and show how they plan to adapt to the impacts that climate change will bring.^[1]

But so far, only 25 countries, covering around 20% of global emissions, have submitted their plans, known as Nationally Determined Contributions.

In Africa, they are Somalia, Zambia and Zimbabwe.

This leaves 172 still to come.

The nationally determined contributions are very important in setting out countries’ short- to medium-term commitments on climate change.

They also provide a direction of travel that can inform broader policy decisions and investments.

Aligning climate plans with development goals could lift 175 million people out of poverty.

But arguably only one of the submitted plans – the UK’s – is compatible with the Paris Agreement.^[2]

We are climate scientists, and one of us (Piers Forster) leads the global science team that publishes the annual Indicators of Global Climate Change report.

This report gives an overview of the state of the climate system.

It is based on calculations of the net emissions of greenhouse gases globally, how these are concentrating in the atmosphere, how temperatures are rising on the ground, and how much of this warming has been caused by humans.

The report also looks at how extreme temperatures and rainfall are intensifying, how much the sea levels are rising, and how much carbon dioxide can still be emitted before the planet’s temperature exceeds 1.5°C more than it was in pre-industrial times.

This is important because staying within 1.5°C is needed to avoid the worst impacts of climate change.

Our report shows that human-caused global warming reached 1.36°C in 2024.

This boosted average global temperatures (a combination of human-induced warming and natural variability in the climate system) to 1.52°C.

In other words, the world has already reached the level where it has warmed so much that it cannot avoid significant impacts from climate change.

There is no doubt we are in dangerous waters.

Our dangerously hot planet

Although last year’s global temperatures were very high, they were also alarmingly unexceptional.

The data speaks for itself.

Continued record high levels of greenhouse gas emissions have led to rising atmospheric concentrations of carbon dioxide, methane and nitrous oxide.

The result is rising temperatures that are rapidly eating into the remaining carbon budget (the amount of greenhouse gases that can be emitted within an agreed time).

This will be exhausted in less than three years at current levels of emissions.^[3]

We need to face this head on: the window to stay within 1.5°C is essentially shut.

Even if we can bring temperatures back down in future, it will be a long and difficult road.

At the same time, climate extremes are intensifying, bringing long-term risks and costs to the global economy but also, importantly, people.

The African continent is now facing its deadliest climate crisis in over a decade.^[4]

It would be impossible to imagine economies operating without fast access to trusted data.

When share prices plummet or growth stalls, politicians and business leaders act decisively.

None would tolerate outdated intelligence on sales or the stock market.

But when it comes to climate, the speed of climate change often outpaces the data available.

This means fast decisions can’t be made.

If we treated climate data as we do financial reports, panic would ensue after each dire update.

But while governments routinely pivot when faced with an economic downturn, they have been far slower to respond to what key climate indicators – the Earth’s vital signs – are telling us.

What needs to happen next

As more countries develop their climate plans, it’s time for leaders across the globe to face the hard truths of climate science.

Governments need to have fast access to trusted climate data so that they can develop up-to-date national climate plans.

The national climate plans need to take a global perspective too.

This is really important for fairness and equity.

For example, developed countries must acknowledge that they’ve emitted more greenhouse gases and take the lead in presenting ambitious mitigation efforts and in providing finance for other countries to decarbonise and adapt.^[5]

In Africa, the UN is hosting UNFCCC Climate Week in Addis Ababa in September.

As well as making plans for COP30, there will be sessions on accessing climate finance and ensuring that the transition to zero human-caused carbon emissions by 2050 (net zero) is just and equitable.

The summit also aims to support countries that are still working on their national climate plans.

If nationally determined contributions are implemented, the pace of climate change will slow down.

This is vital not just for the countries – and economies – currently on the frontline against climate change, but for a functioning global society.

Just five of the G20 countries have submitted their 2035 plans: Canada, Brazil, Japan, the United States and the United Kingdom.

But the G20 is responsible for around 80% of global emissions.

This means that South Africa’s current G20 presidency can help to ensure that the world prioritises efforts to help developing countries finance their transition to a low-carbon economy.^[6]

Another worrying factor is that just 10 of the updated nationally determined contributions have reaffirmed or strengthened commitments to move away from fossil fuels.

This means that national climate plans from the European Union, China and India will be key in testing their climate leadership and keeping the Paris Agreement’s 1.5°C temperature goals alive.

Many other countries will be scrutinising what these countries commit to before they submit their own national climate plans.

The data in our report helps the world to understand not just what’s happened in recent years, but also what to expect further down the track.

Our hope is that these and other countries submit ambitious and credible plans well before COP30.

If they do, this will finally close the gap between acknowledging the climate crisis and making decisive efforts to address it.

Every tonne of greenhouse gas emissions matters.
