The science of heatwaves, health, and wildfires: Why was the summer of 2026 so hot? - with Clair Barnes, Gary Konstantinoudis and Alisha Fuller-Armah
Summary
This episode examines the record-breaking 2026 European heatwaves, with Imperial College researchers Dr. Clare Barnes and Gary Konstantinoudis explaining the meteorological causes and using attribution science to link a significant proportion of heat-related deaths directly to human-caused climate change. They discuss the rapid normalization of extreme temperatures and the urgent need for better public health planning. The episode also features Dr. Alicia Fuller-Armer, who presents "draconite," a sustainable bio-leather technology that solidifies under intense heat to protect infrastructure…
