Bringing climate solutions to the bedside.
When Hurricane Maria made landfall on Puerto Rico it devastated the island but also caused national shortages of intravenous saline, a backbone of basic medical care when the supply chain was put out of commission.
Hurricanes, wildfires, extreme heat, and other consequences of burning fossil fuels and climate change don’t just threaten our health, they threaten the ability of medical providers to deliver care to all those who need it.
It’s essential that health care providers understand how climate change could impact their clinical practice, be empowered to safeguard their patients’ health, and use their voices to engage the health care community and public to act on climate change.
Harvard Chan C-CHANGE runs Climate MD, a program focused on:
- Working with community health clinics
- Demonstrating climate impacts to health care delivery in medical journals
- Preparing medical leaders on climate and health
- Changing the national media narrative on climate change
- Communicating directly with patients
Working with frontline health clinics
We are working with frontline health clinics to protect patients’ health from climate shocks like heatwaves, hurricanes, flooding, and wildfires. Our programs work with clinic providers, staff, and patients to prevent harm from the climate crisis and improve health equity.
Learn about patient-centered climate resilience and our work with frontline health clinics.

Demonstrating climate impacts to healthcare delivery in medical journals
We reach health care professionals by publishing and amplifying research on patient-centered climate action, leading the yearly analysis tracking the impact of climate change on human health in the U.S. Policy Brief for the Lancet Countdown, and demonstrating the connections between climate change and pediatrics, climate-informed primary care, psychology, emergency medicine, surgery, internal medicine, cancer, pulmonology, infectious diseases, and more.
Preparing medical leaders on climate and health
Our team co-hosts the Health Effects of Climate Change, a massive open online course that has been taken by more than 100,000 students in over 100 countries, Harvard University’s Climate Change and Health Fellows for emergency medicine physicians, and the Climate Health Organizing Fellows program for U.S. health professionals.
We work with medical schools to integrate climate change into curricula using clinical cases and targeted curriculum, outlining the first residency curricula to better prepare doctors for climate change and identifying climate and health initiatives at educational institutions.
Changing the national media narrative on climate change
We serve as the media’s go-to source for climate change and health information, regularly interviewing with top-tier national and health media and hosting workshops and media trainings for organizations on how to effectively communicate about climate and health issues.
Communicating directly with patients
We regularly publish information about how people can stay healthy in a changing climate through serving on the boards of Parents Magazine and Pattrn from The Weather Channel, our collaborations with the Harvard Health Letter, one of the most trusted and widely-read sources of health information in the world, our fact sheets on kids and climate, and our monthly Climate Optimist newsletter.

Federal investments in climate change and health research are inadequate says Harvard analysis
Critical knowledge gaps hinder an evidence-based response and are perpetuated by scarce federal research funds.
