Abstract
At present, there is little guidance on how to communicate the dangers relating to hot weather events and on how to better prepare for them. Social responses to hot weather risks need to be a priority as populations around the world become more exposed to these under a changing climate. In this commentary, we argue that policy interventions focused on improving resilience to hot weather need to be more closely aligned with broader sustainability challenges and more effectively incorporate communication, behaviour, and social insights. With a particular focus on the UK, we highlight the risks of not taking these into account and outline ways in which policy-making on hot weather events could be improved, by drawing on international best practice and supporting decision-making within a range of relevant institutions across the health, transport and housing sectors.
