The objective of this article is to examine the role of doctors and health professionals in communicating the health impacts of climate change and exploring how achieving climate objectives is co-beneficial to public health objectives. This article identifies the main interpretative frameworks for climate change communication identified in the literature, contextualizes the challenge of climate communication in the field of public health, and analyses the element of trust, without which the communication process is likely to fail. Awareness-raising strategies must therefore create appropriate contexts that allow the public to perceive climate change as a relevant and immediate issue. Further, to be properly considered, such information must be issued from a source the public trusts. After providing a general framework within which to examine the role of doctors and health professionals in climate communication, message content is examined along with trust in message sources and in the medical profession, and the perceptions among and training of medical professionals concerning the climate challenge are considered.The literature reviewed in this article represents the body of climate change communication research related to the role of the doctor, an area of growing interest. This review provides a timely and complete analysis of the literature on the subject with the goal of starting a necessary, but too-long postponed, multidisciplinary dialogue.
