Summary

In this interview, epidemiologist Kevin Jean discusses the various health impacts of climate change. He begins by quantifying heatwave-related deaths, noting 60,000 deaths in Europe in 2024 and 7,000 in France in 2022. He explains the ‘harvesting effect’ and the physiological mechanisms behind heat-related mortality, including cardiovascular and respiratory failures. The conversation covers the link between heat and violence, citing a 5% increase in domestic violence per degree of temperature rise. Jean also discusses the indirect effects on HIV transmission through drought-induced social changes. Air pollution is addressed, with climate change exacerbating ozone and particulate matter levels, leading to increased respiratory diseases. The potential for vector-borne diseases like dengue and chikungunya to establish in Europe is explored, with record autochthonous cases in France. The interview touches on mental health impacts, including eco-anxiety, and the strain on healthcare systems. Jean concludes that climate change acts as a risk multiplier, affecting nearly all known health risks.
