A recent international study suggests that heat-related deaths may increase in Mumbai and other major Indian cities due to rising temperatures. The study points out that while cities like Mumbai, Delhi, and Bangalore have been focusing on immediate responses to heat waves, there is a lack of long-term strategies in place. The findings emphasize the urgency for implementing comprehensive solutions to prevent fatalities caused by extreme heat, particularly in urban areas projected to experience substantial temperature rises. It is crucial for authorities to introduce essential interventions and involve civil society in climate action efforts to address the existing gaps in state capacity. This study underscores the importance of proactive measures to mitigate the impacts of heatwaves and protect vulnerable populations in India’s urban centers.
