At the beginning of 2025, extreme heat already affected many parts of the world, with temperatures exceeding 45°C in cities in Brazil, India and South Sudan. Heatwaves are on the rise globally, getting hotter and longer due to climate change.

Cities are on the frontlines to prevent, prepare for and manage the impact of heatwaves. More and more cities work on action plans or put in place innovative measures to protect their residents from heat exhaustion.

In the framework of Heat Action Day, join us for an insightful event co-organized by the Global Cities Hub and the Red Cross Climate Centre focusing on how to beat the heat and increase climate resilience in cities.
