The solution to the problem is also, in part, the remedy.
Nearly half of young people aged 16-25 report negative daily functioning due to climate anxiety and distress, requiring mental health support integration. Climate impacts on emotions—solastalgia, eco-anxiety, climate anxiety, ecological grief—are emerging phenomena requiring new vocabulary and clinical understanding.

WHO presents evidence that climate change significantly affects mental health and proposes five policy approaches for governments to minimize psychological impacts on populations.
The World Health Organization arrived at a United Nations conference in Stockholm this week with a stark message: the climate crisis is not only reshaping the physical world, it is reshaping the human mind. The organization presented a practical guide to governments outlining five approaches to protect mental wellbeing as environmental conditions deteriorate. The timing was deliberate—the Stockholm+50 conference, held June 2-3, marked fifty years since the first major UN environmental summit, a moment to take stock of what has changed and what remains undone.
The scientific case is building, though the field is young. Research into how climate change affects mental health only began drawing serious attention around 2007, and there is still much to learn. Yet the evidence accumulating now is difficult to ignore. Nearly half of young people between sixteen and twenty-five report that climate anxiety and distress are interfering with their daily lives, according to global studies cited by Diarmid Campbell-Lendrum, who directs the WHO's climate crisis unit. That scale of impact demands recognition in mental health programs, he argues, not as a footnote but as a central concern.
The emotional landscape of climate change is still being mapped. People are experiencing sadness, fear, despair, grief, and a sense of powerlessness—feelings that researchers and clinicians are working to understand and name. New terms have emerged in recent years: solastalgia, eco-anxiety, climate anxiety, ecological grief. These are not clinical diagnoses yet, but descriptions of a shared human experience that did not have language before. The challenge is real. How do you treat something you cannot yet name? How do you distinguish between rational concern about an existential threat and a mental health condition requiring intervention? Campbell-Lendrum emphasizes the need for care in how these terms are used—people experiencing climate distress should not be stigmatized, yet those who need psychological support must receive it.
The vulnerability is not evenly distributed. Farmers watching salt water destroy their fields, communities facing unprecedented drought, indigenous populations whose lands are changing faster than anywhere else, people in remote or conflict-affected regions—these populations face compounded risks. When climate shocks force migration, the losses multiply. A farmer displaced by salinization or drought loses not only livelihood but home, community, identity, and the psychological anchors that hold a life together. The mental health consequences can be severe, and they often arrive without adequate support systems in place.
Campbell-Lendrum frames the challenge as both urgent and solvable. The five recommendations from the WHO document call for integrating climate considerations into mental health policy and vice versa—ensuring that psychological wellbeing shapes decisions about climate mitigation and adaptation. Governments should build on existing global commitments like the Paris Agreement, involve communities in solutions, and close the vast gaps in mental health care that already exist. He notes something important: many of the actions needed to reduce emissions—cutting air pollution, reducing car dependence, encouraging walking and cycling, fostering contact with nature, supporting sustainable diets—deliver direct benefits to both physical and mental health. The solution to the problem is also, in part, the remedy.
Yet the scale of the challenge is immense. Even without climate change, mental health systems are failing. An estimated one billion people worldwide live with at least one mental health condition, and most receive no care at all. Governments spend roughly two percent of health budgets on mental health. The WHO's warning is clear: all of these numbers will worsen as climate impacts accelerate. The organization is calling for a shift in how governments think about the crisis—not as an environmental problem with health consequences, but as a health crisis that demands the same urgency and resources as any other threat to human wellbeing. The window for action is closing, Campbell-Lendrum says, and it is closing fast.

The climate crisis is also a health issue—including mental health—but we cannot neglect the root problem. We must cut carbon emissions rapidly, and many of the actions required also bring direct benefits to both physical and mental wellbeing.— Diarmid Campbell-Lendrum, WHO climate crisis unit director

La Conversación del Hearth Otra perspectiva de la historia
Why is the WHO focusing on mental health now, when the climate crisis has been documented for decades?
Because the evidence connecting climate change to psychological harm is only recently becoming undeniable. Young people are reporting real, measurable impacts on their daily functioning. We're not talking about abstract worry—we're talking about anxiety that prevents people from working, studying, sleeping. That scale of impact demands a response.
But isn't some of that anxiety rational? If the climate is genuinely destabilizing, shouldn't people be concerned?
Exactly. That's the trap. The concern is completely rational, which is why we have to be careful not to pathologize it. We can't treat climate distress as a disorder when it's a reasonable response to real danger. But we also can't ignore the people whose distress becomes disabling. The line between rational concern and clinical need is blurry, and that's where the real work begins.
Who suffers most from these mental health impacts?
The people who are already most vulnerable—farmers losing land to salinization, indigenous communities watching their territories transform, people in remote areas with no safety net. When climate shocks force migration, the psychological damage compounds. You lose your livelihood, your home, your community all at once. That's not just stress; that's a cascade of losses that mental health systems are completely unprepared to handle.
The WHO mentions five approaches. What's the most important one?
Probably the integration piece—making sure that when governments design climate policy, they're thinking about mental health, and when they design mental health policy, they're thinking about climate. Right now these exist in separate silos. But they have to talk to each other, because the solutions overlap. Reducing emissions also means cleaner air, more walking, more time in nature—all things that improve mental health directly.
Is there hope in what the WHO is proposing?
There's realism, which is a form of hope. They're not pretending this is easy or that we can solve it without massive change. But they're also pointing out that we don't have to choose between fighting climate change and protecting mental health. The same actions do both. That's not nothing.
