Global climate change has been called the greatest health threat of the twenty-first century, and its effects are already being felt in communities around the world. Clinicians have a central role to play in combating health risks related to climate change and raising awareness about its health effects, but how can individual health professionals tackle such an enormous problem? This month on Ethics Talk, we talk with photographer and medical student Jordan Emont about how art can communicate the health impact of climate change, hear from patient Louise Hobden about the health challenges of hot and humid days for people with chronic obstructive pulmonary disease, and discuss the effect climate change will have on global health and how clinicians can help intervene with Dr. Kate Weinberger.
