This issue provides a deep dive into the growing system-wide risks posed by extreme heat and the innovative strategies being implemented to combat it, as 2024 sets new temperature records. It highlights critical topics such as the inadequacy of Celsius-based heatwave measurements, and advocating for the adoption of wet-bulb temperature metrics to better predict heat risks. It explores ground-breaking heat action plans, including ward-level strategies that prioritise vulnerable populations, such as outdoor workers, migrants, and low-income communities.
Major outputs include urban cooling measures like green infrastructure and nature-based solutions to address the urban heat island effect, while grassroots efforts focus on informal workers in cities like Ahmedabad, where extreme heat threatens livelihoods and public health. Further, it examines the intersection of extreme heat and migration, underscoring the challenges faced by displaced populations in temporary shelters. International mechanisms like the Loss and Damage Fund are also discussed, highlighting their potential role in supporting climate adaptation at local levels.
