Psychology’s essential role in addressing climate change and environmental threats
Several key articles by eminent psychologists have been published in recent years stressing psychology’s essential role in addressing climate change and environmental threats.

Barriers to behaviour change
If so many people are concerned about climate change, the environment and sustainability, why are more not taking action? Changing behaviour is more difficult than people usually imagine.
Psychologists working on environmental issues have identified many different barriers that get in the way, ranging from structural barriers like lack of money (e.g., to purchase solar hot water) or infrastructure (e.g., access to public transport), to psychological and social barriers (e.g., perceived status in having large homes/cars; conflicting goals and aspirations).

Promoting sustainable behaviour, motivating behaviour change
Research on behaviour modification teaches us much about how to motivate people and groups to behave in particular ways. The use of incentives, feedback, rewards, knowledge about stages of change, norms and modelling have all been researched in the context of promoting sustainable behaviours.

Communication, social norms, modelling
How do we communicate effectively about a topic like climate change that is complex, confusing, uncertain, sometimes overwhelming, and often emotionally and politically loaded?
In order for people to become motivated and empowered to adopt the needed changes to reduce environmental threats, they must be able to interpret and respond to information. The impact of communications on behaviour varies dramatically based on how the communication is developed and delivered. Knowledge about effective communication comes from psychological research on diverse topics including social norms, conservation psychology, persuasion and (social) marketing.

Health impacts of climate change
Climate change is recognised as the greatest health threat of the 21st century and has significant impacts on physical and mental health and psychosocial wellbeing.
There are likely to be some (modest) positive health consequences from climate change (for example, reduced extreme cold weather events in some locations); however, climate change is already and will predominantly have mostly negative, and in some circumstances devastating, impacts on human health, particularly on those with low adaptive capacity.
Climate change also has significant psychosocial and mental health impacts on individuals and communities. Rising sea levels, droughts and extreme weather events cause loss of habitat, water and food shortages, and threats to home and livelihood. The psychosocial and mental health impacts of these changes include displacement, dislocation from community, financial and relationship stress, multiple losses, increased risks of depression, anxiety-related disorders, grief and substance use disorders, and can lead to increased risks of national insecurity, violent conflict and increased mass migration. Indirect mental health consequences come in response to perceptions/fears of unprecedented scale of risks and observation of world-wide effects.

Whilst the vast majority of people claim to be concerned about the climate, it is also the case that large numbers of people also avoid, minimise, switch off, or distance themselves from effectively engaging with the problems. A small but noisy minority actively deny that there even is a problem. How do we understand this, and how do we solve the “It’s Not My Problem” problem?
Adaptation and coping
Psychologists and other social scientists have contributed to a crucial body of work on psychological adaptation.
Alongside physical and structural adjustment to environmental changes, adaptation also includes a range of coping actions that individuals and communities may take in response to environmental threats, as well as psychological processes that both precede and follow behavioural responses.
Considerable psychological adaptation to climate change takes place within individuals. It includes people’s psychological responses, changes, and adjustments to the threat and implications of climate change, as well as to the psychological consequences of unfolding physical environmental impacts of climate change. These psychological processes mediate behavioural adaptations and adjustments.
Psychological adaptation includes: how people perceive and understand the problems, how they react emotionally, how they decide what to do, and how they behave in response to the problems.

Environmental dispute resolution
As they have done in peace psychology and alternative dispute resolution at local and international levels, psychologists can make crucial contributions to organising fair and sustainable rules for sharing global resources, advocating for just and equitable solutions, and adding to the development of conditions and mechanisms for achieving national and international consensus, adherence and successful outcomes for climate change mitigation and adaptation strategies.

Climate change risk perception
Psychological research on risk perception explores how people perceive, appraise and understand environmental problems and how concerned people are (or not), and how motivated they are to take action (or not).

Worldwide we know that children are among the most vulnerable people in any population to the negative impact of environmental degradation, poverty, natural disasters and violent conflict. What are the impacts of climate change on children, how are children thinking about climate change and environmental threats, and how do we instil environmental values in children?
Overpopulation and overconsumption
Overpopulation and overconsumption have long been recognised as the twin drivers of many environmental problems. The simple fact is that growth in population and consumption cannot continue unabated on a finite planet. Unchecked population growth means depletion of water and other resources, and increases in land degradation, famine, migration, conflict over scarce resources, violence and war. The worst population problems, however, are arguably in developed countries because of our extraordinarily high per capita resource consumption. How do we slow, regulate or even halt growth?
