One of the most overlooked
consequences of climate change? Our mental health

The
findings of one study after another are punctuated by breaking news or the
direct experience of wildfires, hurricanes and floods that forced thousands of
people to evacuate, damage property, and erase tangible reminders of our past.
More
ubiquitous, but less publicized, are the millions of people who are exposed to
heat waves, long-term droughts, rising sea levels, and eroding coastlines,
forcing them to move elsewhere or spend large sums of money building
communities that are habitable.
We
respond to such news and events in a variety of ways. Some of us sink into deep
despair or simply resign ourselves to the inevitability of global climate
change. Some of us live with the trauma of having survived life-threatening
extreme weather events.
Some of us actively avoid the reality of climate change or spend considerable psychic energy denying that it is happening or, at the very least, denying our responsibility for its happening.

Each
of these responses represent a challenge to our mental health. For instance,
people exposed to life-threatening extreme weather events are more likely to
experience post-traumatic stress disorder, depression and anxiety.
People
exposed to prolonged heat waves are more likely to make poor decisions that
place them at risk for death or severe injury.
People exposed to long-term drought are more likely to experience depression, interpersonal violence and thoughts of suicide.
People exposed to sea level rise and coastal erosion are more likely to experience anxiety and interpersonal conflict with others in their community.

However,
these mental health challenges are perhaps the most overlooked consequences of
climate change.
Increasing temperatures and heatwaves, the spread of emerging infectious illnesses, and the widespread concerns about food security in drought-plagued regions of the world all threaten our physical health.
Environmental
changes that threaten our livelihoods, access to food, and habitability of our
communities lead to widespread unemployment and poverty, civil conflict, and
dislocation.
“Climigrants”

Practically
everyone has heard about the fighting in Syria, but few are aware that the
conflict was preceded by years of drought in the eastern part of the country
that led to a massive displacement of more than a million residents to the
western part of the country.
Many
of the migrants fleeing to Europe for the past seven years came from the Sahel
region of Africa that has experienced drought for a decade or more.
Many of those migrants arriving at the southern border of the United States during the past two years have come from the "dry corridor" of Central America, which has also experienced periods of drought alternating with periods of extreme flooding.

In both instances, food insecurity and reduced agricultural productivity have been associated with increased levels of violence and poverty. For residents of these and many other parts of the world affected by global climate change, the only alternative is to leave.
While
migration is considered a form of adaptation to climate change, it also comes
at a cost. Climate refugees or "climigrants" often are able to bring
little with them apart from the mental health problems created by the
environmental changes and their threats to health and well-being.
Many
are exploited by human traffickers who extort huge sums of money to assist them
in their passage elsewhere, only to abandon them in their greatest time of
need.
Many
seek resettlement in countries and communities that are suspicious of and
hostile to outsiders, especially those with great needs and few resources who
represent different cultural traditions and speak different languages. All of
these contribute to further risks of mental health problems, including
depression, anxiety, post-traumatic stress, substance use and interpersonal
violence.
The
old, the young, women, less educated, the poor, and those with a pre-existing
mental health condition are especially susceptible to these problems.
Youth
at risk

While
each of these mental health problems are significant, potentially affecting
hundreds of millions of people in the next 30 years, they pale in comparison to
the problems that are manifesting in response to the existential threat of
global climate change.
These
problems have been given specific names like 'ecoanxiety', 'ecoparalysis', and
'solastalgia', the latter referring to the distress and isolation caused by the
gradual removal of solace from the present state of one's home environment.
Young
people are especially vulnerable to these syndromes. A recent survey of youth
living in the United States commissioned by the Washington Post and Kaiser
Family Foundation found that more than 70 percent believe climate change will
cause a moderate or great deal of harm to people in their generation. About 57
percent of those interviewed reported that climate change makes them feel
afraid.
Climate
coping
The
good news is that the same survey found that 52 percent reported that climate
change makes them feel motivated to do something about it, and one in four
teenagers have participated in a walkout, attended a rally or written to a
public official to express their views on the subject.
These
youth are not alone. Science tells us that people who engage in active forms of
coping have better mental health.
In
addition to working to mitigate global climate change by reducing carbon
emissions and promoting clean energy and lifestyle changes, there are numerous
ways to combat these mental health consequences.
Understanding
the scope and scale of mental health impacts associated with climate change in
general and climigration in particular is an important first step to developing
and implementing services designed to treat or prevent these impacts.
These
include planned relocation of communities, public health education, violence
prevention, risk communication, use of evidence-based treatments for mental
health problems, training of non professionals in delivering psychological
first aid and other interventions, personal engagement in environmental
conservation, and promotion of positive psychological outcomes associated with
climate change.
All
of this will take a concerted effort on the part of mental health
professionals, experts in other fields, and, most importantly, those who have
already experienced the consequences of climate change and those most likely to
experience similar consequences in the future.
When
it comes to climate change and mental health, however, the future is now.
