<h3>Background</h3> Climate change has well-documented impacts across the cancer care continuum, from increased carcinogenic exposures to disruption of health care systems required for cancer prevention, screening, diagnosis, treatment, and follow-up care. Incorporating the impact of climate change into oncology training will be essential for future physicians. When surveyed, only 13% of U.S. medical students felt they were receiving adequate climate change and health (CCH) education. Yet there is no standard climate curriculum in medical education in part due to an abundance of essential topics that must be covered. In collaboration with a Climate Health Resources Education (CRHE) pilot, we present the development of climate health and oncology educational resources aimed at providing succinct, accessible, and evidence-based resources for educators to incorporate CCH into medical curricula. <h3>Methods</h3> In partnership with CRHE, oncology topics with associated evidence-based learning objectives were established. Recruitment of content creators took place via email distribution lists, professional societies (e.g., Healthcare Without Harm, Medical Students for a Sustainable Future), social media (i.e. Twitter), and word of mouth. Working groups with medical students, residents/fellows, faculty advisors, and an expert advisor were established. Using standardized CRHE templates, medical students wrote and designed practice-based learning cases, while residents created associated PowerPoint slide decks. Faculty mentors and expert advisors were responsible for content review and ensuring accuracy. <h3>Results</h3> For the oncology lectures, a collaborative working group of eight healthcare professionals was formed (4 medical students, 4 residents/fellows, 3 faculty advisors, and 1 expert advisor). Over the course of four weeks, two lectures with associated practice-based problems and slides were developed on the topics of, 1) particulate matter pollution and lung cancer; 2) climate change impacts across the cancer control continuum. The oncology CCH educational resources were incorporated into CRHE's topic-based longitudinal curriculum and will be made publicly available for online, open-access distribution across health training programs nationwide. <h3>Discussion</h3> It is essential for physicians-in-training to be educated on the topics of CCH, the impact on cancer control, and the effect on our communities. Future physicians will need to be prepared to adopt and advocate for climate-smart, sustainable, and resilient care to meet the shifting needs of a vulnerable population affected by a changing climate. This initiative exemplifies the collaborative effort that will be required to integrate climate health topics into medical education, including oncology-specific topics. We look forward to reporting further results on the adoption and implementation of the curriculum.
