Physician advocacy for climate change mitigation is justified by seven criteria including physicians’ efficacy, expertise, public trust, and proximity.
Climate change mitigation reforms of government policy, medical curricula, and health professions organizations should be the focus of physician advocacy.
The adverse health effects of climate change should be the focus of physician advocacy efforts and of conversations between physicians and their patients.
Gene editing to enhance humans’ adaptability to climate change should consider safety, harm to be averted, succeeding generations, and social consequences.
Public health and climate stabilization historically have competed for public funds, but investment in either good has the potential to advance both goods.
