South Asia’s Extreme HeatSouth Asia’s Extreme HeatCoverage from The Conversation, Climate Analytics, and others

South Asia’s extreme heat is affecting daily life, health, work, and essential services across India, Pakistan, and Bangladesh.
Heatwaves are linked to heat stress, illness, lost working time, crop and livelihood pressures, school disruptions, and growing demand for cooling, with informal and low-income workers often facing the greatest exposure and least protection. The subject also examines responses such as heat action plans, urban cooling, labor safeguards, social protection, insurance, resilient buildings, and cleaner, more reliable power systems. Together, these issues show how heat risk is shaped not only by temperatures, but also by inequality, infrastructure, and preparedness.
