India's Deadly Heat Causing Health, Economic Crisis

India's extreme heat is causing tens of thousands of deaths and damaging the economy.
Heat waves have caused over 24,000 deaths in India since 1992 and spurred increases in air pollution and Himalayan glacier melt.
Up to 90% of India now endures extreme heat, and the country is unprepared for the crisis.
By 2050, extreme heat may cut India's GDP by up to 2.8%, reduce quality of life for 480 million, and cut outdoor work capacity by 15%.
Productivity losses from extreme heat may already be costing India's economy 5.4% of GDP.
