Climate disasters and mental health

What are climate disasters?

Climate disaster is a general term commonly used to describe catastrophic consequences of human-caused climate change.

While climate disasters include the impacts from slower moving chronic conditions, such as sea level rise, melting permafrost, and extinction of species, the focus in this entry will be on acute events. Acute events include extreme weather events (EWEs): fires, floods, storms (hurricanes and tornados), and heat waves. While no individual EWE can be attributed to the climate crisis, the global increase in temperature from greenhouse gas emissions has increased the frequency and intensity of EWE.s

EWEs and chronic climate disasters directly and indirectly strain our economies, our politics, and societies in general. The direct, ripple effects, and cumulative toll of this strain affects our personal mental health, that of our families, and collectively, our communities. It can define and destabilize nations – and ultimately our world.

Climate-driven disasters have increased by factor of five in the last half century (from 1970–2019), according to the World Meteorologic Organization. The United Nations Office for Disaster Risk Reduction reported that in the two decades from 1995–2015 alone, worldwide disasters have wounded, displaced, or required emergency assistance for four billion people; half a million people have died.

What is disaster mental health?

Disaster mental health focuses on the emotional toll of climate disasters and the urgent need to integrate psychological care into all disaster response programs. Psychological care includes mental health evaluation first aid, treatment, and consultation in the context of disasters.

How do climate disasters impact mental health?

Emotions: Although studies quantifying emotions associated with disasters are limited, ordinary human empathy can tell us a lot: When the place you call home is burned down by wildfires, blown away by tornados, flooded or leveled by hurricanes; when you lose your possessions, maybe your pets, your livelihood, the comfort and predictability of everyday life in a familiar community; witness injuries, illnesses, and deaths – the resulting mix of fear, anger, sorrow, and trauma can easily send a person into overwhelming states of distress.

Typical phases of disasters

Disaster mental health experts have identified common patterns of individual and community reactions to disasters. These are illustrated below. (Reproduced with permission from Morganstein and Ursano, 2020.)

Pre-disaster Phase: Anticipatory fear is experienced in the early stages, followed by the trauma of the event itself. Timely warnings can give the opportunity to take safety measures, which can reduce the feeling of helplessness and boost the feeling of having (some) control. In contrast, denial of the danger leads to avoidance and inaction, heightened vulnerability to disaster, and a more pervasive sense of helplessness.

Impact Phase: After a natural disaster, an identifiable low point is seen, followed by the feeling that the worst is over, and the recovery process can begin.

Heroic and Honeymoon Phases: These occur in the immediate aftermath of a disaster. They are marked by shows of altruism, generosity, and a sense of shared purpose. Vows to rebuild, replant, and restore are often heard. As people reach out to assist each other, a sense of community cohesion is often felt. This phase often draws media attention showing scenes of heroes rescuing those in need. Such attention from the outside world helps people feel that the rest of the world “cares”.

Disillusionment: As time goes on, recovery may be prolonged; the response to the harms and destruction may be experienced as inadequate to the needs of the impacted people. Community cohesiveness may fade. Disillusionment and cynicism can replace the prior sense of hopefulness. A range of uncomfortable emotions may emerge: despair, anger, helplessness, sorrow and grief at the losses. Feelings of invisibility and abandonment may emerge, driving outrage directed at the government for not providing enough help, and for not taking enough preventive measures. Similar feelings may be directed at other entities. This phase can persist depending on the availability of resources and adaptive capacities.

Reconstruction Phase: This phase is defined by the period when an individual or community attempts to come to terms with the actual event, faces and grieves losses, and confronts the emotional aftermath of life after the trauma. This “new beginning” is a time when the focus is on moving forward. An anniversary of the disaster and other triggers, however, may cause symptoms and setbacks to this process.

How we “carry on” after a climate disaster is influenced by many factors, including our backgrounds, current mental states, life experiences, resources, personalities and temperaments. The nature of the event itself plays a role in influencing the extent of psychological injury: the intensity of the feeling of powerlessness generated, the “merciless” character of incidents, the pace, suddenness, degree of damage, loss of life and injury and the extent to which people personalize these incidents.

Beyond the phases: The upward trend in the image of the “Reconstruction Phase” implies the promise of improvement and resolution. However, recovery is far more complex, and far from guaranteed. While many victims of climate-related EWE may return to prior functioning and successfully rebuild their lives, those with the fewest resources and least support may not be able to put their lives back together and risk suffering enduring associated emotional sequelae.

What’s more, those who experience repeated or ongoing disasters may not have a chance to recover emotionally before the next disaster hits. This compounds the harm because each disaster deepens emotional vulnerability. Vulnerable communities may become defined by the impacts of repeated climate trauma.

Anxiety among those who fear that another climate disaster may be just around the corner can rise to the level of “pre-traumatic stress“. For example, residents of New Orleans have reported that just seeing a storm cloud can trigger anxiety of flooding.

Unequal impacts

The impacts of climate disasters are “brutally unequal“. Vulnerable and special groups particularly at-risk during climate disasters include:

Poverty and the biases linked to racism are “multipliers” of risk because they impede access to the resources that help individuals and communities endure, recover and adapt. At greatest risk are areas in developing countries, where poverty is widespread and resources are limited.

Consequences if we don’t reduce carbon emissions drastically

The intensity and frequency of hurricanes, floods, heat-related events, wildfires and other human-caused natural disasters will continue to increase.

Our mental health care system is already stretched to the limit. It is grossly unprepared to respond to the rapidly unspooling effects of the climate crisis. Calls for mental health professionals to help with the mounting psychosocial toll will become more intense; can we doubt that they will feel overwhelmed? Now is the time to shape an approach that prepares us for the responses that will be needed. The current model – a one-to-one delivery approach – is not sufficient, and will need to cede ground to a public health model, with an all hands on deck, community-wide and population-based approach. Collaboration with experts specifically trained for this new approach will be a critical component.

Addressing the impacts of climate disasters

It is essential that mental health care be integrated into the emergency trauma response to climate disasters.

While the Federal Emergency Management Agency (FEMA) and other entities such as the Red Cross respond to disasters, their work is primarily focused on physical impacts. Psychological care has not been adequately provided, despite overwhelming research documenting the psychological and behavioral health consequences.

Disaster response requires a multidisciplinary approach: People who have specialty training and experience as first responders, emergency medical technicians, and disaster management experts capable of coordinating services with different entities (multiple governmental agencies, physicians, and other health care providers). There is a significant gap in addressing the impact of disasters on mental health. So far, mental health professionals have played a limited role in disaster preparation and response. This gap cries out to be closed.

Mental health professionals have unique skills to bring to the needs of communities and individuals following disasters. Disaster response training for mental health professionals should be made available in the programs of all disciplines related to mental health. Training should include:

  • Disaster preparation: Integration of mental health considerations and interventions into training multidisciplinary disaster response teams. Research shows that collaboration among public health stakeholders (for example, local health departments, academic health centres, and faith-based organizations) can plan and implement effective disaster mental health preparedness plans. Mental health professionals should be trained to work with disaster management experts, community organizations, governmental agencies, first responders, schools, and other entities to plan for coordinated responses.
  • Disaster Response: providing on the ground “emergency” psychological first aid.
  • Assistance in shaping public messaging.
  • How to identify people most vulnerable to severe psychological responses to ensure no traumatized group is overlooked, and to prioritize resources for those most in need. This is a nuanced assessment that not only protects the vulnerable, but prevents over pathologizing or prematurely labeling those having acute stress reactions, which may not last long-term.
  • How to identify and advocate for the establishment of safe spaces and practices conducive to recovery for the special needs of vulnerable populations.
  • Teaching basic coping skills.
  • Recovery interventions: Coordinating care and resource provision for affected individuals and groups alongside primary care providers, disaster agencies, and community organizations.
  • Follow up: After early recovery efforts, ongoing support for the long-term needs of those with persistent difficulties must not be ignored.

What more might we need to know?

Action areas for research, policy, and practice include:

  • Defining best practices for interventions that can be scaled up for large populations.
  • Establishing metrics to measure progress.
  • Designing treatments to address the impacts of multiple traumas from repetitive disasters.
  • Persuading professional organizations to immediately begin the process of creating a skilled workforce trained to meet the growing psychosocial vulnerabilities.  
  • Creating a subspecialty in climate change and mental health to train mental health professionals is urgently called for.

We know a lot about what is needed to address climate change and develop energy sources that break our reliance on fossil fuels – the drivers of climate change and climate disasters. What we need to do now, more than anything, is to turn what we know into what we do.
