The unprecedented shifts brought on by climate change ripple far beyond rising temperatures and extreme weather; they reach deep into the minds and hearts of all living beings. Anxiety, grief, and a profound sense of loss now shadow our collective experience. This climate-related mental distress is not only felt by people but also echoed in the land, waters, plants, and animals to which we are inseparably connected. As ecosystems unravel, the mental health of humans and non-human relatives becomes a shared story of vulnerability and resilience.
Climate Change and Rising Anxiety
The reality of climate change is no longer a distant worry; it is a present and palpable force shaping the mental landscapes of countless individuals. Across ages and cultures, climate anxiety, sometimes called eco-anxiety, has emerged as a defining psychological response to the accelerating devastation of the natural world. This anxiety is not simply fear of future disasters but an existential reaction to loss, uncertainty, and powerlessness.
Signs of Climate Anxiety
People experiencing climate anxiety often report:
- Persistent worry, rumination, or panic about environmental catastrophe.
- Feelings of helplessness, hopelessness, or grief, often described as “climate grief.”
- Disturbed sleep, including insomnia or nightmares, can be linked to climate crises.
- Physical symptoms may include an elevated heart rate, stomach upset, or fatigue.
- Social withdrawal, or conversely, sudden bursts of activism.
- Existential questioning about the future, meaning, and humanity’s role in planetary degradation.
- Heightened sensitivity to environmental news and changes, sometimes leading to overwhelm or burnout.
How Climate Anxiety Shapes Worldviews
Climate anxiety is shifting how people relate to themselves and the world:
- A fractured sense of security: The predictability of seasons and natural resources, as well as the scaffolding of cultural and personal identity, is disrupted.
- Heightened interdependence: For some, anxiety strengthens awareness of interconnectedness, prompting a search for meaning beyond individualism and consumerism.
- Urgency for change: Anxiety can fuel activism and demands for systemic transformation.
- Collective trauma and grief: Climate change becomes a shared mourning for lost species, landscapes, and lifeways.
- Shifts in values: Many are turning away from materialism toward ecological stewardship, simplicity, and relationality.
Climate Anxiety in the Indigenous Context
For Indigenous peoples, climate anxiety is layered with cultural grief, the loss of land, language, ceremony, and traditional livelihoods. This grief is deepened by colonial histories that severed people’s relationships with ancestral territories and more-than-human kin.
Yet, Indigenous worldviews also carry profound resilience. Seeing humans as part of a web of life provides a relational refuge, a framework for navigating climate anxiety through connection, ceremony, and stewardship. Unlike dominant Western approaches that often treat mental health in isolation, Indigenous perspectives integrate ecological realities into healing.
Supporting Mental Well-Being Amidst Climate Anxiety
Meeting climate anxiety as both a personal and collective challenge requires approaches that nurture resilience:
Land-based healing and connection: Spending time on the land, engaging in cultural practices, and restoring bonds with ecosystems.
- Community support and dialogue: Safe spaces to share fears and grief, build solidarity, and mobilize collective hope.
- Eco-literacy and empowerment: Education in climate science, Indigenous land stewardship, and practical action to counter helplessness.
- Mindfulness and grounding practices: Techniques to calm and regulate overwhelming emotions.
- Centering Indigenous knowledge: Teachings of balance, renewal, and reciprocity enrich mental health frameworks with holistic approaches.
Indigenous Ways of Knowing: Medicine for Mind, Heart, and Spirit
Indigenous worldviews offer vital teachings for healing and well-being. Central among these is interconnectedness, the recognition that humans, earth, waters, animals, plants, and ancestors form one living web. This understanding fosters a holistic approach to mental health that weaves together mind, heart, body, and spirit.
Ceremonies, storytelling, land-based practices, and seasonal cycles cultivate balance and harmony, offering medicine for both individual and collective resilience. Reconnecting with Mother Earth is a profound step toward healing, inviting us to listen deeply to the rustle of leaves, the flow of rivers, the flight of birds and, in that listening to rediscover grounding, purpose, and hope.
Empathy for More-Than-Human Relations
Climate change also affects our non-human relatives. Plants wither, animals migrate or perish, and waters warm and recede. Indigenous teachings remind us that these beings hold life, spirit, and memory. They, too, suffer displacement and loss. Cultivating empathy for them expands our circle of care and underscores that mental and environmental health are inextricably linked.
When we engage with land, waters, and wildlife not as resources but as relatives, fractured relationships begin to heal. This relational awareness lays the foundation of stewardship rooted in respect and reciprocity, integrating the need to confront climate change.
Reconnecting with the Land
Reconnection is both sacred and practical. Land-based healing, traditional ecological knowledge, and Indigenous ceremonies are increasingly recognized within Indigenous communities and beyond as powerful supports for mental health.
Spending time on the land harvesting plants, participating in a ceremony, or simply observing seasonal rhythms nurtures awareness, patience, and resilience. It roots us in the present, affirms belonging, and reminds us that we are part of a living community. Through this reconnection, humans can find strength in relationships, solace in shared struggle, and hope in reciprocal care.
Moving Forward Together
The climate crisis compels us to rethink mental health in relational terms, recognizing that human well-being is inseparable from the well-being of the land and all its beings. Indigenous knowledge offers enduring wisdom for this path. By honouring interconnectedness, embracing land-based healing, and nurturing empathy for all relations, we can cultivate mind, heart, and spirit medicines essential for resilience.
Together, human and more-than-human kin can walk toward healing, balance, and renewed hope grounded in the living teachings of the earth we call home.

The head of the United Nations has launched an initiative aimed at holding artificial intelligence companies accountable for their exploding environmental impacts, including their carbon emissions, the amount of water and land used for data centres, and the energy they consume.
During a speech at London Climate Action Week on Tuesday, António Guterres noted that AI can accelerate climate solutions, among other key challenges, and said its potential must be harnessed.
“But AI is also hungry for land, water and power,” he emphasised, adding that the data centres needed to run AI models already consume more electricity than most countries.
The UN Secretary-General repeated a call he first made in July 2025 for all big AI companies to commit to power every data centre with renewable energy by 2030.
Some tech firms have announced they are sourcing or building out clean energy to run their hubs, but growing power demand is also contributing to gas-fired generation in the US, according to data from Global Energy Monitor.
The International Energy Agency (IEA) estimates that data centres are set to more than double the emissions from the electricity they use between 2024 and 2030 in a high-growth scenario. But AI’s use could lead to far larger reductions in the energy sector through efficiency gains if adopted widely.

‘No more hidden costs’
Proposing the new “AI Environmental Transparency Initiative” on Tuesday, Guterres also urged big AI firms companies to measure and publicly disclose the full environmental impact of their systems, including their carbon, water, and land footprints.
“No more hidden costs. No more shifting the burden onto those least able to bear it. It is time to come clean,” he said in a major speech on responding to the world’s twin climate and energy crises. “If AI is to help build a better future, it must be honest about what it costs us now.”
A report issued earlier this month by the UN University Institute for Water, Environment and Health noted that most current assessments of AI’s environmental cost focus on carbon emissions from training models. But, it added, this misses a substantial part of the picture.
Every kilowatt-hour of electricity for AI also carries a water footprint, from cooling and generation, and a land footprint, from infrastructure and supply chains, it said.
Explainer: Will AI data centres make or break the energy transition?
The report estimated that AI data centres globally could consume 945 terawatt-hours of electricity annually by 2030 – more power than all but five countries and roughly twice France’s 2025 consumption.
Offsetting this carbon footprint by 2030 would require growing some 6.7 billion trees over 10 years, it calculated. Producing power for the data centres would consume water equal to the basic needs of 1.3 billion people in sub-Saharan Africa for a year and take up land of more than 14,500 square kilometers, roughly twice the Jakarta metropolitan area.
The European Union said earlier this month it will develop minimum energy-efficiency standards for both new and existing data centres, with a “needs assessment” due by 2027, Reuters reported. It’s also planning a sustainability label for data centres, covering criteria including water use and clean energy supply – but that has been delayed.
US community push-back
Asked after his speech what the response had been, the UN chief said “we’ll see”, without giving more details.
But, he argued that, in his view, the push for transparency “is perfectly reasonable and even positive for the AI industry, because eventually some people will say that they consume much more than they really do”. “I think the truth is essential,” he added.
Concerns about the environmental impacts of AI and the infrastructure needed to run the technology have led to growing opposition in some communities, especially in the US.
This month, Monterey Park in Los Angeles County was the first city in the United States to enact a citywide prohibition on data centres through a voter-approved ballot measure. The developers behind a proposed centre in the area had already pulled the project in April amid an increasingly hostile local environment and regulatory uncertainty.
The vote that stopped a data center: US communities query resource-hungry AI
According to nonprofit Data Center Watch, around $64 billion-worth of data centre projects nationwide were delayed or blocked between May 2024 and March 2025 as communities pushed back against them.
Industry lobby groups argue that data centres can provide economic benefits in their host communities. According to the US-based Data Center Coalition, which represents big operators and developers, data centres generate tax revenue, support construction and technical jobs, and provide infrastructure needed for cloud computing, scientific research and AI development.
The industry has also challenged claims that data centers necessarily raise electricity costs for households.
Force for good?
The UN chief said benefits can be few in the places that are home to the data centre, while “communities are often left in the dark about the environmental impact of the infrastructure rising around them”.
Guterres said companies have an “obligation” to be clear and open about the services they are offering but also the level of resources they require.
“Transparency is essential for the decisions that communities must make – and transparency is essential even for the future of artificial intelligence, and to make sure that artificial intelligence is essentially a force for good,” he told an audience of climate professionals in London
A senior UN official told journalists ahead of Tuesday’s announcement that the AI industry has started to talk about and disclose some of their impacts, but those efforts are not yet comprehensive enough.
The hope is that the new initiative will “encourage the industry to come together and take further action on it”, the official said.

Welcome to Cited, your essential guide to new climate research.
In the news
SCIENCE ‘UNDER ATTACK’: Climate Home News reported that “dozens” of countries called out “coordinated attacks” aimed at “undermining the role of climate science” at UN climate talks in Bonn, Germany, last week. According to the outlet, the countries said that UN decision-making had to remain based on the “best available science”, including the reports of the Intergovernmental Panel on Climate Change. One negotiator said that India and Saudi Arabia “opposed calls in draft texts to encourage scientific work on scenarios that would minimise the magnitude and duration of any overshoot of 1.5C”, the article noted. For more, read Carbon Brief’s summary of the negotiations.
REPORT OPPOSITION: “Oil industry allies” in the US are targeting a report on extreme weather attribution, due to be published by the National Academies of Sciences, Engineering and Medicine, according to Politico. The outlet reported that the “heightened scrutiny – which involves a secretive opposition research group scouring scientists’ emails – has prompted two people to leave the 15-person panel tasked with producing the report”. Separately, the Guardian reported that the Trump administration has “reversed its decision” to dismantle the Ocean Observatories Initiative, a $368m deep-sea observation system.
SUPER EL NIÑO: BBC News reported that the US National Oceanic and Atmospheric Administration announced that El Niño had “officially begun”. Forecasts suggest the event could be among the “strongest ever recorded”, it added. Meanwhile, a “vigorous debate” is taking place about whether climate change is making the El Niño phenomenon more intense, according to the New York Times. The outlet explained that some scientists see the run of “comparatively strong” El Niño events in recent decades as an indication that “climate change is supercharging El Niño”. However, it added that “others say there is no clear evidence to support that theory”.

Spotlight
Introducing: Project Cosmos
Carbon Brief explains how it built a major new database of climate science research and unveils a new ranking of the 500 most highly cited publications, authors and institutions in climate science.
This week, Carbon Brief launched Project Cosmos – the world’s largest and most complete database of climate change research.
The database features more than 1.8m academic papers, books and reports, capturing the vast body of human knowledge about climate change that has accumulated over more than a century of academic study.
The climate science “universe” is based on reports from the Intergovernmental Panel on Climate Change (IPCC), which are recognised as the world’s most authoritative summaries of the latest climate science.
Since its first report was published in 1990, humanity’s knowledge about human-caused climate change has ballooned. The IPCC has published six sets of reports in total – each one longer than the last.
In total, IPCC reports reference more than 100,000 other papers, books and reports. This is the core of our climate science universe. Carbon Brief then built on this core, by looking at four other sources of data. Read more about how the Cosmos database was created here.
Every single publication in the Cosmos database is linked to at least one other through references. Visualising these links reveals a “galaxy” of references. In the image above, each colour and cluster reveals different topics and densities of research. Explore the galaxy in an interactive map here.
Cosmos 500
As part of an initial wave of preliminary analysis to demonstrate the scope of the Project Cosmos database, Carbon Brief has ranked the 500 most highly cited publications, authors and institutions in the database.
The most highly cited climate scientist is Prof Philippe Ciais, who has spent almost four decades researching the planet’s carbon cycle – and the ways in which humans have been impacting its balance. Carbon Brief recently interviewed Ciais in Paris.
The US tops the tables for the most highly-cited authors and institutions. Almost half of the 500 most highly-cited authors are from US institutions. This raises particular concerns for the future of climate science, as American climate scientists and institutions are coming under attack under the Trump administration.
Experts from global south countries account for only 4% of all authors in the Cosmos 500. China stands out as the most highly-cited global south country. Meanwhile, only 10% of authors in the Cosmos 500 are women.
There are many possibilities for future avenues of research using the Cosmos database. Over time, the database could be used to reveal, for example, how interest in different areas of climate science has changed over time, plus identify potential knowledge gaps and, thus, opportunities for future research.
Carbon Brief invites researchers – including academics, journalists and analysts – to submit their own proposals for co-authored studies, literature reviews and analytical projects.
