Climate Anxiety: The Psychological Impacts of Climate Change 

Are We Doomed?

Climate change refers to long-term changes in the Earth’s weather pattern and temperatures due to increased fossil fuel emissions. Studies have shown that humans have become the leading cause of climate change as the Earth’s surface is now around 1.1°C (2°F) warmer than in the 1800s. While that may not sound like a significant rise, the United Nations notes that it can lead to major environmental changes with catastrophic consequences including water scarcity, flooding, declining biodiversity, severe fires and storms.[1] Such dire warnings and predictions have led to psychological distress about what the future may hold. 

Climate Anxiety

Ecological anxiety (i.e., eco-anxiety) is the psychological discomfort arising from the threat of an ecological disaster, which itself is seen as uncertain or difficult to control. Climate change anxiety falls under the category of eco-anxiety and is explained as “the distress caused by climate change as people become anxious about their future.”[2] Nadarajah et al. (2022) note that climate change has become a source of concern for many international organizations including the United Nations and the World Health Organization (WHO) as they now consider this ecological threat to be the greatest danger to mental health within the next century.[3]  

The consequences humanity is already facing have been shown to have effects on their mental health and well-being. For example, excessive heat has been associated with increased aggression, suicide, and hospitalizations for mental illness. Air pollution caused by fine air particulate matter can lead to cognitive impairment and behavioral problems in vulnerable populations. Extreme heat and severe weather events also pose a greater risk to children’s development due to their thermoregulation not being fully developed and their greater dependency on adults and social support.[4] 

Climate anxiety can be caused due to either direct causes (e.g., trauma resulting from extreme weather events) or indirect causes (e.g., trauma from a perceived threat to the future). These causes can have different impacts on an individual’s symptoms of climate anxiety.  Cognitive-emotional impairments include difficulty sleeping, crying, nightmares, and rumination. Functional-impairments of climate anxiety include the inability to work or socialize with others.[5] Other mental health disorders have been associated with climate-related trauma such as post-traumatic stress disorder (PTSD), depression, anxiety, suicidal thoughts, and survivor guilt. Some individuals can even develop mood disorders or maladaptive eating due to the great uncertainty the future can hold and the intense fear that comes from questioning the future of their existence.[6]

Cross-National Investigation of Climate Anxiety 

While climate anxiety is just beginning to be studied, most research conducted has been done in Western, Educated, Industrialized, Rich Democracies (WEIRD). However, more emphasis is being drawn on the need for worldwide research on how global warming is affecting global populations psychologically. A 2021 study conducted in 50 different countries by Peoples’ Climate Vote found 64% of 1.2 million respondents believed climate change to be a global threat. Additionally, a survey conducted by Yale University in 2021 noted that the majority of people from over 30 countries felt climate change would affect them by either a “moderate amount” or a “great deal”.[7] Further, a 2021 poll conducted by Hickman et al., in the Global South found that Brazil (86%), India (80%), Nigeria (70%), and the Philippines (92%) all indicated high levels of fear for the future. Adversely, Russia reported some of the lowest concerns at 9.6%,[8] but this may be attributed to that population’s lack of climate-related information due to extreme internet/information censorship enacted by their government.[9] 

Due to the great fear of climate change, many studies, such as Ogunbode et al., (2022), have shown a direct relationship between climate anxiety and pro-environmental behaviors, such as supporting climate policies and climate activism. This is especially prominent among European, democratic, affluent countries - as their citizens are likely to have fewer political or financial barriers to expressing their concerns and have more opportunities to learn about global warming and its consequences. Additionally, pro-environmental behaviors are linked with individualist countries, as people feel a greater need to act on their personal beliefs.[10]

Generation Z &the Fear for Their Future 

While most climate anxiety research involves WEIRD countries, a global trend is beginning to emerge in cross-national data: Generation Z (i.e., those born 1997-2012) is more concerned with climate change than the generations before them. The Lancet Planetary Health (2021) conducted a global survey in 10 different countries asking young people (16 to 25 y/o) about their climate anxiety and their reaction to governmental response.[11] From this study, 83% of young people reported they were at least “moderately worried” and 59% reported they were “very worried” about global warming and its threat to the future. Additionally, 45% expressed that their worry affected their daily functioning such as concentrating, working, socializing, eating, and spending time in nature. The study also reveals respondents' fear for their future, with 75% indicating that the “future is frightening” and 56% feeling “humanity is doomed”.[12]

These pessimistic views are understandable, as Generation Z and those after will bear the harsh burden of climate change. A 2021 review by Hickman et al., found Gen-Z and future generations will face extremely high disease risk due to environmental changes. Hickman’s study also examined young people’s view on government response to climate change, and found respondents felt “frustrated by unequal power, betrayed and angry, and disillusioned with authority, drawing battle lines”.[13] The ecological crisis has gotten to the heart of younger populations, with one 16-year-old noting, “I think it’s different for young people. For us the destruction of the planet is personal.”[14] 

Young people have even turned to legal action in the hope of pushing the government to take action on the climate crisis. The case of Juliana v. United States was filed in 2015 after 21 children and young adults (8-19 y/o) asserted the government’s inaction on climate change was violating their right to life, liberty, and property. Additionally, the youth plaintiffs argued it was the government’s duty to protect public groups, which they failed to do as they permitted and encouraged fossil fuel usage.[15] However, in 2020 the case was thrown out stating the issue needed to be raised with the executive and legislative branches of government versus the courts.[16]

Many factors play into why this generation feels more strongly about climate change - the most prominent is media exposure. Younger generations are becoming more exposed to news, images, and reports of environmental disasters due to constant access to the internet and social media from their smartphones, and thus frequently witness the consequences of global warming.[17] Moreover, repeated exposure to negative news on climate change increases their awareness of the threat and increases their anticipation of the consequences. This then leads to additional information-seeking as a reactive behavior to the uncertainty of the future.[18] Finally, the social norms around climate change within younger generations are more pro-environmental, thus giving them a sense of security in their feelings. Ogunbode et al., (2022) add that when people around an individual react to the consequences in a similar way, they feel justified in their behaviors.[19]

Mitigating Climate Anxiety 

While the threat from climate change is a grave concern for many people, there are steps individuals can take to lower their anxiety as well as combat the crisis. Individuals can also decrease their climate anxiety as well as make a difference by supporting pro-environmental behaviors (e.g., saving energy at home, avoiding food waste, and using public transportation) and promoting policies and organizations that push to help the environment.[20] Taking pauses or meditating can also calm certain anxieties people may have about the climate crisis. Mindfulness can allow people to focus on the present moment and learn compassion for themselves and nature. Further, individuals can use contemplative time to reflect on the complexity of climate change, understand change cannot come overnight and can allow them to reflect on the power they hold to enact change and help make a difference. Psychotherapy, particularly cognitive behavioral therapy (CBT), can be useful for people to employ and work through their concerns with a mental health professional.[21] Particular components of CBT that can be useful in combating climate anxiety include:[22] 

  • Using problem-solving skills to cope with difficult situations

  • Learning to develop a greater sense of confidence in one’s own abilities

  • Facing one’s fears instead of avoiding them

  • Learning to calm one’s mind and relax one’s body

Additionally, individuals can seek clinicians who practice ecotherapy, or nature therapy, as these practitioners may have a greater awareness of current climate concerns. This is especially useful as ecotherapy focuses on reconnecting with nature and exploring how people’s lives are part of a greater system. If conducted in a group format, ecotherapy allows people to explore their personal relationships with nature as well as share with others their emotions and worries,[23] which can further validate their feelings and help someone feel less alone.

Future Steps 

Although climate anxiety is a relatively new concept, more emphasis needs to be placed on investigating the impacts of climate anxiety on non-WEIRD populations. Additionally, focusing on how different international factors such as education, religion, and region affects people’s feelings towards global warming will allow a better way to educate and create more effective strategies to help slow climate change.[24,25] Moving forward, it is imperative for mental health professionals to continue to develop strategies that allow clients to feel their concerns are being heard, as this phenomenon will only worsen as the consequences of climate change continue to rise. 

If you or someone you know is struggling with depression, hopelessness and/or anxiety regarding climate concerns, please reach out to a licensed mental health professional (e.g., a psychotherapist, psychologist or psychiatrist) for guidance and support.

Doomsday Prepping: Reactionary Behavior or Inherited Instinct?

The Prepper Next Door

In 2011, the television show Doomsday Preppers began airing on National Geographic, bringing mainstream attention to what appeared to be an obscure phenomenon.[1] The series featured “preppers” stockpiling bunkers with enormous amounts of food and ammunition while conducting drills to prepare for apocalyptic events such as an electromagnetic pulse (EMP) destroying modern technology or the collapse of society due to civil war.[2] As this trend became more popular, sales of preserved food surged 700% between 2009 and 2014.[3] Since then, interest in the practice has continued to increase with “prepper” groups uniting on social media and companies churning out the supplies needed to survive a doomsday scenario.

What is Prepping?

Prepping has been defined as, “The management of stockpiled household items in anticipation of market disruption.”[4] Individuals considering themselves preppers may perceive the current structure of society to be a landscape of risk in which the institutions that control access to energy, food, healthcare, shelter, water and waste disposal are associated with risks related to nuclear fallout, toxic pollution, climate change, resource depletion, and potential ecological collapse.[5] Activities of “prepping” tend to revolve around the six core needs of medicine, security, shelter, nutrition, hydration, and hygiene.[6]

Lessons from COVID-19

Smith & Thomas (2021) note that before the COVID-19 pandemic, doomsday prepping was sometimes associated with terms such as paranoia, conspiracy mentality, social dominance orientation, cynicism, and conservatism - but attitudes of the general public changed when COVID-19 lockdowns began in early 2020.[7] Shortages of toilet paper rippled throughout the country as the public frantically panic-shopped while preparing to stay home for an undetermined amount of time.[8] Two years later, supply chain issues related to the pandemic still continue, with 2022 seeing shortages in Sriracha, lumber, baby formula, and cream cheese.[9] To many, the previously-mocked lifestyle of prepping no longer seemed like a wild idea, but rather an intelligent way to prepare for uncertainty that may lie ahead.[10]

The pandemic spurred the immediate reaction of flight from densely-populated urban environments, with Manhattan experiencing a 15-20% reduction in population during the first few months.[11] By the end of 2020, the average new home purchase had shifted an additional 3 miles away from urban centers, though some analysts believe that urban flight may be temporary.[12,13] Some who migrated to rural areas started discovering the joys of hobbies like gardening, cooking from scratch, and creating homemade goods.[14] This shift in priorities and interests, combined with years of rotating shortages often attributed to disastrous events such as Hurricane Ian or Russia’s invasion of Ukraine, worked together to result in a public change in perception towards prepping.[15] Fetterman, (2021) believes this shift is not necessarily unfounded since recent research conducted in Denmark and the US indicates that those who had an interest in prepping were better-equipped psychologically, during the pandemic.[16]

The Surprising Effect of Media on Resilience

The beginning of the millennia produced a fascination with post-apocalyptic worlds, as can be seen by the popularity of shows like The Walking Dead and video games like Fallout 4.[17] While media has at times been credited, or possibly accused, with sewing the idea of individual self-reliance during the apocalypse, Dr. Troy Rondinone, historian of American culture, states these stories also provided narratives of hope by showing that the best chances of survival are through democratic, interracial neighbors selflessly helping each other.[18]

This concept was recently reinforced by research conducted by Scrivner et al., (2021) which found that during the COVID-19 pandemic, those who had engaged with thematically-relevant media (such as pandemic-related media and horror films) demonstrated greater psychological resilience and preparedness.[19] Additionally, horror fans showed greater resilience than fans of the prepper genre (including zombie, apocalyptic, and alien-invasion media) indicating that “trait morbid curiosity” and exposure to frightening fiction may give audiences the opportunity to practice effective coping strategies and results in positive resilience.[20]

Ancient Preppers

While prepping may sound like an extreme response to our current structure of society, historically, there may be precedence across cultures to indicate otherwise. The art of processing and storing food is what allowed humans to survive times of winter or long voyages overseas.[21] When agriculture was being developed, food storage served as a form of risk management that protected against crop failure.[22] To preserve food for winter, humans learned the art of shucking, shelling, boiling, blanching, and canning which gave humanity the benefits of reducing food waste, improving nutrition, and increasing leisure time.[23] Historically, food storage systems were needed to secure an excess amount of food that was greater than what was required for immediate annual household needs, provided sustenance through seasonal or yearly shortages, and allowed an excess amount for trading.[24]

Evidence of the importance of food storage to early humans is supported by research conducted by Blasco et al., (2019) on the Qesem Cave in Israel which found that during the Middle Pleistocene period, butchery techniques indicated that preservation was used for delayed consumption of bone marrow and bone fat.[25] Similarly, in Jordan, evidence gathered from a 19,000-year-old archaeological site showed evidence of gazelle meat being smoked and dried for preservation.[26] Recent evidence has also emerged indicating that prehistoric West Africa used clay pots to assist in the processing and storing of plants 10,000 years ago.[27]

During the Roman Empire, food storage was so advanced that Aelius Aristides, a second century grammarian, described it as the warehouse of the world since Roman consumers not only had access to food from different regions, but they were available year-round.[28] In ancient Peru, stone structures (qolcas) were constructed on the northern face of a mountain where icy wind produced natural refrigeration; they were used as a system of community food storage to help withstand times of bad harvest.[29] In Ireland, hundreds of butter cakes have been found (one dating back as early as 5,000 years ago) in peat bogs which prevented the growth of bacteria and decomposition.[30] Around the same time, China began using salt as one of the most important food preservatives.[31] Considering the long global history of humans storing food to avert shortages, it may not be that unusual that modern humans today have the instincts to engage in a similar behavior.

Prepping Across the Modern World

One unique aspect of prepping in modern America is the emphasis on self-sufficiency, the American ideal of individualism.[32] Some preppers in the US strive for independence and desire to break free from the institutions that regulate access in modern society.[33] Yet the prepping phenomenon is not unique to the United States.

In 2019, it was estimated that one-in-five consumers in Britain were storing medicine, food, and water in preparation for supply chain interruptions related to Brexit (the highly-debated decision for the United Kingdom to leave the European Union).[34] Yeoh (2020) reported that in Singapore, some preppers aim to use a methodical mindset towards preparation which provides a contingency plan for any crises.[35] This point is illustrated by descriptions of a family that is fully prepared with harnesses to quickly escape their 5th floor apartment in the event of a fire, and supplies of oxygen tanks in case a family member tested positive for COVID-19 but needed to wait for medical treatment.[36] It should also be recognized that not all cultures view prepping as an unusual activity. Nakkiah Lui, a First Nations actress and comedian from Australia who created the sitcom Preppers, describes her journey watching shows about entering the world of prepping and thinking, “Being a First Nations person… that idea of survival and prepping for the worst, and survival being part of your history…that’s definitely something I’ve inherited.”[37]

Inherited Instincts or Learned Behavior

With the historical context of food storage and preparedness across cultures, the question can be raised, “Is the act of prepping the result of human instincts or reactions to perceived threats in the environment?” In response to this question, different theories have emerged. Research conducted by Lindstrom et al., (2016) found that in dangerous environments, genetic preparedness and social learning co-evolve simultaneously.[38] In both humans and animals, preparedness behaviors have the tendency to reduce foraging efficiency, but can result in higher rates of survival which indicate the trade-off that needs to take place between safety and flexibility.[39]

Life History Theory (LHT) is an explanatory framework for behavior that integrates the perspectives of evolutionary, social developmental, and ecological theories while considering the amount of effort needed to invest in achieving a goal and the trade-offs that are required.[40] Living in an unpredictable environment tends to lead to activities that are focused on the present and may involve riskier behavior, while living in a more predictable environment leads to behavior that is more focused on long-term strategies such as lower levels of risk-taking and greater regard for social rules.[41] Since emergency preparedness requires a focus on long-term strategies, it tends to be adapted by those with a slower life history; those with a faster life history may experience greater fear of future disasters.[42]

The Instinct Theory of Motivation suggests the environment plays the role of triggering the cognitive abilities that are produced through natural selection.[43] Theorists from the Santa Barbara School of Evolutionary Psychology take a nativist outlook to cognitive instinct, teaching that cognitive mechanisms are hardwired and inherited genetically from our ancestors through the natural selection of genes.[44] In contrast, the California School Cultural Evolutionists endorse the view that our psychology is primarily culturally inherited, through social learning that may be underpinned by cognitive instincts.[45] Turner & Walmsley, (2021) state the view that cultural learning and social cognition are the result of a substantial amount of genetic inheritance.[46]

The way a person views apocalyptic scenarios may also offer insight into people’s beliefs about humans and society.[47] For example, it may be easier for a person to express that they would be fearful of how people would behave in an apocalyptic world than to say that they distrust people.[48]

Prepping and Mental Health

The historic and genetic aspects of this topic all work to raise the question, “Is prepping a psychologically healthy behavior?” Mills (2019) presents an understanding that prepping is a response generated by general anxiety about a variety of potential disasters in the future, which are fueled by reports and government warnings in mainstream media.[49] However, fieldwork interviewing preppers found that the majority of concerns were non-apocalyptic and focused instead on temporary disasters.[50] In terms of existential psychology, prepping thoughts and behavior may be an outlet for processing feelings of uncertainty.[51] To address these concerns, self-sufficiency can serve as an emotional management strategy that channels the emotional energy generated over risk into the more pleasurable activities of building water systems, gardening, and canning.[52]

While analyzing the events of 2020, which included the recent pandemic, the storming of the Capitol, protests for racial justice, a record-breaking hurricane season, and unprecedented freezes in Texas that left many without power, Psychologist Adam Fetterman determined that the majority of time people were cooperative and helped each other during these events.[53] Dr. Fetterman, who states that he previously believed prepping behavior to be a little irrational, found that while the COVID-19 pandemic showed that cynical views on human nature were largely unwarranted, there was some legitimacy about concerns to the supply chain.[54] This raises the question of how real threats to temporary access to resources can be addressed in a way that is psychologically healthy.

Psychologist Marty Nemko recommends avoiding hoarding, but stocking enough supplies to last a month, then supplementing them with smaller purchases as needed.[55] He recommends prioritizing water, food, medication, first aid supplies, hand-cranked/solar radios and flashlights, motor oil, cash, and back-up internet through a cell phone provider.[56] Taking these basic precautions is considered a productive way to take charge and effectively address concerns about the supply chain.

While preparing for potential disasters is warranted, it is still best to make sure it does not become an all-encompassing preoccupation. A person should consider speaking with a licensed mental health professional if worrying about potential disasters becomes obsessive, anxiety is interrupting eating or sleeping, preparations have negative impacts on a person’s finances, personal relationships are being impacted, or a person feels too overwhelmed to take the steps necessary to prepare for a future event.
