Why Climate Change is Bad for Our Health


Marina Romanello

Executive Director, The Lancet Countdown

Climate change is threatening human health across the globe. Extreme weather events like wildfires and heat waves are causing immediate and long-term health risks, with sometimes deadly results. According to this year’s Lancet Countdown report, which tracks the effects of climate change on human health, the impacts are getting worse.

To address this growing crisis, the recent UN Conference on Climate Change, or COP28, featured its first ever Health Day. Discussions there established the issue as a vital factor in climate negotiations. But the final agreement from the climate talks does not include the phasing out of fossil fuels, which is language many health experts were hoping to see included.

So, how do researchers track the connection between climate change and human health? What are the key indicators? And what do they warn will be the consequences of continuing to burn fossil fuels?

This week host Bill Loveless talks with Dr. Marina Romanello about the intersection of health and climate change. Marina is the executive director of the Lancet Countdown, and a climate change and health researcher at University College London. She has also carried out research in the Buenos Aires Institute of Technology, University of Cambridge, and the Francis Crick Institute. From 2020-2021, Marina helped England’s National Health System develop net-zero commitments.
