In recent years, discussions around the impact of climate change on mental health have tended to focus on climate anxiety.
This distress regarding the future of the Earth and humanity in the face of global warming is, however, far from the full picture.
Research is helping to build a better understanding of the damage that climate change, particularly extreme heat, can cause to mental health.
The latest assessment report on climate impacts from the Intergovernmental Panel on Climate Change (IPCC) concluded with very high confidence that rising global temperatures have “adversely affected” mental health in regions around the world.
Research indicates that heatwaves can trigger increases in both the hospitalisation of people with mental-health challenges and emergency psychiatric visits. People with pre-existing mental-health problems also have an increased risk of dying during periods of high temperatures.
In addition, suicide rates have been shown to increase in higher temperatures and are expected to rise in a warmer world – although the links with climate change are complex and compounded by other factors.
Despite these research findings, significant gaps remain in understanding the biological, psychological, social and environmental interactions between mental health and heat.
And policymakers have a huge amount of ground to make up, with mental health barely featuring in climate-related policies and commitments around the world.
How heat can affect mental health
Being in the midst of a heatwave can feel all encompassing. Generally, being hot and uncomfortable can affect a person’s mood, leading some to feel more irritable and stressed. This can have a knock-on effect on behaviour. For example, research shows that people are more likely to tweet negative comments during a heatwave.
Extreme heat can have even more significant implications for sleep. Research shows that warming nights are eroding human sleep globally – and the effect is three times larger for residents of lower-income countries.
While lost sleep in hot and humid conditions is unpleasant for anyone, for those with mental health problems, poor sleep carries a real risk of making them worse.
Nonetheless, not all heat is bad for mental health. Many people believe that they are happier on sunny days and some research agrees.
For example, a 2023 study in Switzerland found that, in the general population, mood tends to improve as temperatures get warmer. However, the study also found that the opposite is true for people with anxiety, depression and psychosis, who were more likely to experience low mood.
Impacts of extreme heat
The impact of extreme heat on an individual’s mood has implications for social behaviours and interactions.
There is a growing body of research linking extreme heat with an increase in violent behaviour, such as homicides, sexual violence and assaults, which – in turn – can negatively impact mental health.
For example, a study conducted in India, Nepal and Pakistan found that with each 1C increase in the annual temperature there was a 4.5% increase in violent acts. This finding alone is an indicator that heat affects a person’s psychology, but there are so many other factors that need to be considered.
There are other possible social drivers that may explain this link. People living with pre-existing mental-health problems may be more vulnerable to the impact of extreme heat due to societal factors that put them at increased risk.
Due to the relationship between mental-health problems and poverty, people living with mental-health conditions may be more likely to live in less energy-efficient housing, have less access to adaptation mechanisms such as air conditioning, be more socially isolated, or work in occupations that increase their exposure to extreme heat.
Finally, certain medications for mental-health problems – such as some antidepressants or antipsychotics – may disrupt the body’s ability to regulate temperature, meaning that people taking these medications may be more vulnerable in high temperatures. This may explain why people taking these medications have been found to be at higher risk of being hospitalised or dying during heatwaves.
One patient in the UK taking antipsychotics – medication for mental-health problems where symptoms include psychotic experiences – was quoted last year in the BMJ explaining how they were affected by extreme heat. They said:
“[F]or many summers I had also noticed that I struggled to tolerate the heat as the UK weather grew more extreme. I would sweat profusely, my skin would feel clammy, and I would feel very tired, irritable and would struggle to think…I had no idea this was related to my medication.”
Prescribing appropriate medications for certain mental-health conditions and ensuring people taking them are protected from the potential negative impacts of heat represents an important clinical and policy priority.
Research gaps
To date, most studies on climate change and mental health have been conducted in Europe, North America and Australia. This means that there are huge gaps in research for the global south, which is facing some of the most severe impacts of climate change.
A new project called Connecting Climate Minds, which Wellcome funds, aims to develop a research and action agenda on climate change and mental health. As part of this project, 900 people shared their experiences on the impact that climate change is having on mental health around the world.
One of them is Laila, a teacher working in Jordan. She has been suffering from stress, anxiety and depression. At its worst, she confesses that she struggles to teach and finds communicating with the children very difficult.
Over the past few years, these episodes have become more frequent and severe. Her psychologist noticed that Laila’s mental health seemed to worsen during the country’s extreme heatwaves – something that is becoming more and more common in the region.
Watch her interview in full below.
Wellcome is also set to launch a funding call later this year focusing on uncovering the mechanisms underpinning the association between heat and mental health among the most affected communities worldwide.
The aim is to help build global understanding of the biological, psychological, environmental and social links around extreme heat, which will in turn inform better climate resilient solutions and mental health interventions.
Policymaking lagging behind
As with research, there are gaps in policymaking on mental health and climate change.
Most countries do not currently consider mental health within climate change policies, such as heat action plans. At present, only 3% of the climate pledges submitted by national governments under the Paris Agreement mention mental health.
South Australia is among the few states already doing this. The South Australian warning system incorporates public heat warnings, health advisories and targeted support for at-risk groups including those with mental-health conditions, ensuring that they can access help if needed. In Athens, a city exposed to more frequent and severe heatwaves, psychologists are being deployed to support older adults experiencing loneliness in the heat.
Nature-based policies that improve access to green and blue spaces and transport policies that encourage active modes of transport have also been shown to have co benefits for mental health and the environment.
However, for now, climate change represents one of the biggest threats to physical and mental health globally. Extreme heat is deadlier than hurricanes, floods and tornadoes combined. Heat stress can exacerbate underlying illnesses – such as cardiovascular disease, diabetes, asthma – and can increase the risk of accidents and transmission of some infectious diseases. And this is not considering the huge hidden cost of increasing cases of poor mental health.
Research on how climate change is impacting mental health remains limited and disconnected. A better understanding of how and why extreme heat is negatively impacting mental health will be essential to achieve a world where no one is held back by mental health problems, even in the context of a changing climate.

Prepared by a coalition of nine Western Australian union, industry, conservation, and community organisations—including UnionsWA, the Conservation Council WA, and the Smart Energy Council—the WA Clean Energy, Jobs & Industry Plan provides a practical roadmap to transform Western Australia into a clean energy powerhouse while creating thousands of secure local jobs.
Western Australia stands at a pivotal crossroads: lead the global clean energy economy or watch investment, future industries, and secure jobs go elsewhere. The WA Clean Energy, Jobs & Industry Plan outlines a transformative blueprint to harness the state’s world-class solar and wind resources. Discover how legislated renewable targets, green iron manufacturing, and a dedicated regional training strategy can generate tens of thousands of local jobs, lower household bills, and build a resilient, net-zero future for all Western Australians.
WA needs a clear and forward-thinking plan if it is going to become a competitive renewable energy powerhouse and maintain its economic strength through the energy transition.
“Western Australians know a faster renewable energy transition will lower their household expenses and prevent harmful climate pollution. But the community also needs clear direction to ensure this transition will create jobs, lower costs and not cause undue environmental harm.
“Here, sectors representing a broad range of interests have laid the groundwork for those outcomes, clearly outlining what is needed to create a future for WA that is good for the environment, for the climate, for workers and for the economy.
Summary
The WA Clean Energy, Jobs & Industry Plan sets out a strategic roadmap to position Western Australia as a global clean energy superpower while creating thousands of secure local jobs.
The report establishes three overarching goals:
- Creating local employment.
- Maintaining industrial competitiveness.
- Lowering household energy costs
To realize this vision, the framework details actionable measures to follow on from the recent WA Government announcement of a 75% Renewable Energy Target by 2031 for the South West Interconnected System. This includes developing a statewide Renewable Energy Target, coordinating statewide workforce and training pipelines, strategically planning regional infrastructure to safeguard high-value biodiversity and cultural heritage, and ensuring equitable benefit-sharing through household electrification incentives and First Nations equity partnerships. Ultimately, the plan highlights that establishing clear policy and regulatory certainty will unlock lower energy bills, boost power reliability, and secure the state’s global competitiveness in emerging green commodity export markets.
Key Findings
- Statewide Renewable Energy Target and Emissions Reduction Targets: The report calls for a statewide RET and 1.5°C aligned emission reduction targets to remove policy risk, lower capital costs, and attract clean energy investment.
- Transformative Job Creation: Accelerating the transition offers massive employment prospects, including up to 8,800 solar and battery jobs by 2050, as well as 24,000 ongoing and 11,000 construction jobs in a commercial green iron industry.
- Industrial Electrification & Competitiveness: Requiring large gas users to adopt binding electrification timetables and providing concessional financing will protect existing energy-intensive manufacturers from rising energy costs and impending domestic gas shortfalls.
- Green Commodity Export Leadership: Western Australia can build new export markets in green iron, green ammonia, and offshore oil/gas decommissioning by constructing shared common-user infrastructure and setting dedicated Green Commodity Export Targets.
- Coordinated Workforce & Training Pipeline: To address critical skill shortages the plan recommends establishing a WA Clean Energy Jobs Plan 2050, three regional training hubs, and dedicated pathways for female and under-represented apprentices.
- Environmental Safeguards & Community Benefits: Fast-tracked development must be paired with State Planning Policies that avoid high-biodiversity and cultural heritage lands, mandate new data centres to run on additional renewable power, and deliver household electrification rebates and First Nations equity partnerships.
What you can do
WA has an opportunity to lead on sustainable, clean energy and associated industries. You can help by:
- Sending an email to Environment Minister Murray Watt and Prime Minister Anthony Albanese, calling on them to reject Browse.
- Sharing this story to help more Australians understand what’s at stake.
- Encouraging your friends and family to take action.
Countries have completed the first “global review” of their progress towards reversing nature loss by 2030 at the COP17 biodiversity talks in Yerevan, Armenia.
The review “notes with deep concern” that, unless action is “rapidly accelerated”, the goal to reverse nature loss and meet a set of 23 targets by 2030 “will not be achieved”.
It “urges” countries to accelerate action, including by “increased ambition in addressing the gaps”.
Much of the discussions in Yerevan focused on how to raise the necessary funds to help developing countries protect nature.
Some major economies pushed to expand the range of nations that are expected to provide finance, with countries agreeing at the end of the two weeks of talks that non-donors that want to contribute can “signal interest” before COP18.
This came after developed countries failed to meet a target to significantly ramp up nature finance over the last few years.
It also came as a landmark fund agreed at COP16 in Colombia to pay communities for the genetic resources derived from nature stands nearly empty two years on.
The Yerevan talks marked the halfway point of the “Kunming-Montreal Global Biodiversity Framework” (GBF), the “Paris Agreement for nature” first made in 2022 and due to be achieved by 2030.
During the nearly 12-hour-long final plenary, countries voted for Quito, Ecuador, to host the COP18 nature talks, which will be held in 2028.
Countries managed to sign off on all the major ne
