This research explores the impact of climate change on mental health. It employs a systemic approach to analyse the psychological and behavioural responses of individuals and communities to wicked problems.

Abstract: Climate change is the biggest and most prevalent challenge of the 21st century.  Extreme weather events affect not only the ecosystem but also human health. We all are going to be affected by climate change but not equally. Unfortunately, climate change has been affecting those most marginalised - vulnerable group. The vulnerable group is measured by its sensitivity to climate change related health risks, its exposure to those risks, and its capacity for responding to or cope with climate variability and change. Climate change has been enhancing health risks and reinforcing inequalities in the groups. This is a paper review on climate change and its direct and indirect impact on mental health, psychological and behavioural responses to disaster, and the complexity of wicked problems. Furthermore, it is an analyse using design methodologies such as Systems Oriented Design on how to tackle the wicked problems with systemic and individual interventions to enhance the capacity to keep resilience to cope with climate change, mental health, and inequality.
