The role of mental health professionals in the climate crisis: an urgent call to action.

The climate and ecological crisis will constitute the defining public health challenge of the twenty-first century, posing an unprecedented global threat to all determinants of health, and to healthcare delivery systems. We believe that mental health professionals have a crucial role to play in responding to this crisis. Whilst responding to the mental health consequences of the climate crisis will remain a key role for us as mental health professionals, we argue that our remit goes beyond this, and should include advancing public understanding of the climate crisis, highlighting its impact on physical and mental wellbeing, and advocating for systemic changes to limit its impending harms. This paper is an urgent call to action for all mental health professionals to take up a role in the context of the climate and ecological crisis. This paper will describe the relationship between mental health and climate change, and frame it within wider systemic and conceptual frameworks. It will demonstrate that as mental health professionals we are well placed to act as leaders of change-arguing that we have a duty to do so-and suggest actions that can be implemented depending on interests, skill sets and opportunities.

The need for biodiversity champions in psychiatry: the entwined crises of climate change and ecological collapse.

SUMMARY: The past 20 years have seen the disappearance and degradation of biodiversity on earth at unprecedented rates. This phenomenon shares similar drivers to those behind climate change yet requires its own solutions. The twin catastrophes of climate change and biodiversity loss demonstrate how our health is bound up in the vitality of this planet. There has been an increasing effort on the part of healthcare professionals to appreciate this relationship, as evidenced by the growing influence of planetary health as a discipline. However, the health impacts of biodiversity loss have been less focused on than those brought on by climate change. Psychiatry's appreciation of the interface between environments and our health, alongside the evidence for the connection between nature and mental health specifically, prompt psychiatrists to ensure that the institution of healthcare throws its influence equally behind solutions to climate change as well as biodiversity loss.

What mental health professionals and organisations should do to address climate change.

AIMS AND METHOD: The climate change emergency is also a mental healthcare emergency. We seek to provide a framework for what mental health professionals and organisations should do to make their practice more sustainable. RESULTS: There are ethical, legal and organisational imperatives to make mental healthcare more sustainable. Mental healthcare must be refocused with an emphasis on prevention, building social capital and community resilience. Patients must be empowered to manage their own mental health. Efficiencies should be found within the system. Low-carbon ways to deliver care must be found, measured and improved upon. Greater adaptability needs to be built into the system to mitigate the impact of climate change. Sustainability should be integrated into training programmes, and good examples of practice shared and celebrated. CLINICAL IMPLICATIONS: Mental health organisations and individuals must act now to prevent and adapt for the climate and ecological emergency. Sustainable practice is also good practice.
