The origins of climate psychology can be traced back to the work of psychoanalyst Harold Searles and his work on the unconscious factors that influence the estrangement of people from the rest of nature.[2] It has also been strongly influenced by the field of Ecopsychology and its emphasis on the relationships of people with the natural world.[3] Due to the increase in society-wide acceptance of the dangers of climate change, there has been greater interest in understanding the psychological processes underlying the resistance to taking appropriate action, and in particular, the phenomenon of climate change denial.[4] More recently, a literature base by climate psychologists has started to focus on the powerful emotions associated with climate change and planetary-wide biodiversity loss.[5]
