Loss of biodiversity and globalized environmental degradation result in planetary-scale changes which impact human societies.This paper highlights the urgency for public health researchers to integrate a global change perspective into their daily work. The public health community needs to answer several questions, e.g., how to weight the health of present and future generations; how to balance between the possible immediate adverse impacts of mitigating climate change vs long-term adverse impacts of global change; how to limit the environmental impacts of public health intervention; and how to allocate resources. Public health practitioners are faced with a moral responsibility to address these challenges. Key elements to ensure long-lasting, innovative global change and health solutions include (i) empowering the population; (ii) tailoring the framing of global change and health impacts for different stakeholders; (iii) adopting less conservative approaches on reporting future scenarios; (iv) increasing accountability about the health impacts of mitigation and adaptation strategies; and (v) recognizing the limits of science.

Assessing global progress on human adaptation to climate change is an urgent priority. Although the literature on adaptation to climate change is rapidly expanding, little is known about the actual extent of implementation. We systematically screened >48,000 articles using machine learning methods and a global network of 126 researchers. Our synthesis of the resulting 1,682 articles presents a systematic and comprehensive global stocktake of implemented human adaptation to climate change. Documented adaptations were largely fragmented, local and incremental, with limited evidence of transformational adaptation and negligible evidence of risk reduction outcomes. We identify eight priorities for global adaptation research: assess the effectiveness of adaptation responses, enhance the understanding of limits to adaptation, enable individuals and civil society to adapt, include missing places, scholars and scholarship, understand private sector responses, improve methods for synthesizing different forms of evidence, assess the adaptation at different temperature thresholds, and improve the inclusion of timescale and the dynamics of 536 responses.
