Climate change is occurring: where is psychology? The conventional wisdom is that amelioration of the impacts of climate change is a matter for earth and ocean science, economics, technology, and policy-making. This article presents the basis for psychological science as a key part of the solution to the problem and describes the challenges to this both from within psychology and from other points of view. Minimising the personal and environmental damage caused by climate change necessarily is a multidisciplinary task, but one to which psychology not only should, but must contribute more than it has so far.
