As India grapples with extreme heatwaves, experts emphasize the urgent need for comprehensive strategies to protect vulnerable populations and infrastructure. The National Disaster Management Authority (NDMA) is implementing progressive advisories aimed at safeguarding informal workers from the scorching temperatures. However, a leading meteorologist warns that gaps in health data are hindering effective heatwave responses, necessitating plans and funding that extend beyond mere crisis management. Addressing the intensifying climate crisis, local mapping of climate extremes and discussions on the impacts of rising heat stress highlight the deepening challenges faced by coastal communities, particularly in Chennai. The ongoing heatwave exacerbates livelihood crises and forces millions from their homes, underscoring the importance of tackling the growing frequency of heat-related disasters in the region.
