Climate Change Is Already Disrupting Health Care in the U.S.

Yes, the planet is getting hotter, tropical storms are becoming ever more fierce, and the Arctic is melting — but what's that got to do with health care? This week on The Dose podcast, host Joel Bervell explores the intersection of climate change and public health with Admiral Rachel L. Levine, M.D., the U.S. Assistant Secretary for Health. Levine, who oversees the federal Office of Climate Change and Health Equity, talks about how weather-related events are already having a serious impact on our fragile health system supply chain, even though those effects can go unnoticed by the broader public. In communities repeatedly ravaged by storms or heat waves, a lack of blood donations is leading to delays in surgeries and treatment for diseases like sickle cell. In rural Alaska, where the melting permafrost is wreaking havoc on wildlife populations, native tribal communities are forced to rely on shipments of food items that are typically high in sugar and salt — a diet contributing to rising rates of hypertension, diabetes, and heart disease.

"Climate change is the most significant threat to human health in the 21st century, and climate change is having those serious impacts on health right now," says Levine.
