As Europe endures a severe heatwave and the evolving nature of climate change, Genie Godula welcomes Armel Castellan, Technical Advisor for Extreme Heat Services at the World Meteorological Organization (WMO). Castellan argues that extreme heat should be viewed not as a temporary weather anomaly but as a structural public health, infrastructure, and societal challenge. He notes that today’s heat extremes are becoming the new baseline, from which even hotter conditions will emerge. Heatwaves are no longer merely inconvenient events; they are cascading crises impacting human health, energy systems, housing, agriculture, water security, and emergency services simultaneously.
