Heat extremes are already one of the deadliest meteorological events and they are projected to increase in intensity and frequency due to rising CO2 emissions. Thus the risk these events pose to society may increase dramatically and society will need to adapt if the worst impacts are to be avoided. However, uncertainties for understanding the development of extreme heat episodes and their impacts remain large. This session therefore aims to address this challenge, welcoming research which improves our understanding of extreme heat events and how to respond to them. Suitable contributions in this regard may: (i) assess the drivers and underlying processes of extreme heat in observations and models; (ii) explore the diverse socio-economic impacts of extreme heat events (for example, on aspects relating to human health or economic productivity); (iii) address forecasting of extreme heat at seasonal to sub-seasonal time scales; (iv) focus on societal adaptation to extreme heat, including (but not limited to) the implementation of Heat-Health Early Warning Systems.
