Mental Health Impacts

Nearly one in five U.S. adults live with a mental illness. And a growing body of research suggests that climate change can worsen mental health and well-being for these individuals and many others.

According to the latest IPCC reports, “Approximately 20–30% of those who live through a hurricane develop depression and/or post-traumatic stress disorder (PTSD) within the first few months following the event, with similar rates for people who have experienced flooding.”

As Mental Health Awareness Month ends and hurricane season begins, we’re focusing on scientific insights and reporting resources around climate change and mental health.

Links between climate change and mental health
Climate change presents widespread risks to human health. And a growing body of research provides evidence for climate change impacts on mental health in particular.

In February 2022, a major scientific report from the IPCC systematically reviewed evidence linking climate change to diagnosable mental health disorders and broader outcomes for well-being.

This was the first time that mental health was directly discussed and assessed within IPCC reports—a sign of our growing scientific understanding of the topic, and its importance for the global response to climate change.

Climate-related mental health risks
Climate change presents physical hazards that expose people to conditions (e.g., flooding, extreme heat, or drought) that can introduce or worsen mental health risks.

Climate-related risks to mental health and well-being stem from extreme events (like hurricanes, heatwaves, or wildfires) and from gradual, long-term changes (like sea-level rise, rising temperatures, loss of sea ice, and drought).

According to the Fourth National Climate Assessment: 

mental health consequences—ranging from minimal stress and distress symptoms to clinical disorders, such as anxiety, depression, post-traumatic stress, and [risk of suicide]—can result from exposures to short-lived orprolonged climate- or weather-related events.

The latest IPCC reports (see Chapter 7.2.5) also distinguish climate change-related mental health risks that are:

Mental health and well-being outcomes
According to a report from the American Public Health Association, up to 54% of adults and 45% of children suffer depression after a disaster.

PTSD is among the most common mental health outcomes of disasters such as hurricanes:

Adaptation and mental health resilience
The latest IPCC reports (see Chapter 7.4.2) review preventative and post-event responses to reduce the mental health risks posed by climate change—including: improving access to mental health care; incorporating mental health in resilience planning; and training responders in mental health first aid.

The American Psychological Association’s guidance on promoting mental health resilience includes:

POTENTIAL LOCAL STORY ANGLES

How is climate change affecting mental health and well-being in your area?
Consider not only acute impacts (from extreme events) but also gradual impacts (from slow-onset changes like sea-level rise) on mental health in your local area. NOAA’s State Climate Summaries review current and anticipated future climate impacts for each state. Many of these physical hazards have mental health and well-being outcomes, as described in the latest IPCC reports (see Chapter 7.2.5) and in a 2021 report from American Psychological Association. 

Does your local area need post-disaster mental health resources, or have past experience with them?
FEMA maintains a searchable directory of active and past disaster declarations. The Crisis Counseling Assistance and Training Program (CCP)’s FEMA-funded relief grants provide post-disaster mental health services to states, U.S. territories, and federally recognized tribes. Has your local area received CCP grants in recent years, and if so what were the outcomes? 

Who is most vulnerable to climate-related mental health impacts? What is their experience? 
Physical hazards interact with non-climatic factors (ranging from an individual’s personality and pre-existing illness to structural inequity and injustice) to create higher mental health risks in certain populations including: the economically disadvantaged; communities of color; Indigenous Peoples; children; older adults; women; people with disabilities; people with pre-existing mental health diagnoses; and outdoor workers. 

What measures are (or are not) in place locally to mitigate mental health risk and build resilience? 
The recent IPCC reports (see Chapter 7.4.2) review preventative and post-event responses to reduce the mental health risks posed by climate change. To learn whether any of these measures are in place locally, contact local resilience experts using the U.S. Climate Resilience Toolkit directory. 

LOCAL EXPERTS 

The SciLine service, 500 Women Scientists or the press offices of local universities may be able to connect you with local scientists who have expertise on climate change and mental health. Local therapists, emergency responders and nurses may also be useful interviews.
