Heat wave exposure in India in current, 1.5ºC, and 2.0ºC worlds

Heatwaves with large impacts have increased in the recent past and will continue to increase under future warming. However, the implication for population exposure to severe heatwaves remains unexplored. Here, we characterize maximum potential human exposure (without passive/active reduction measures) to severe heatwaves in India. We show that if the global mean temperature is limited to 2.0ºC above pre-industrial conditions, the frequency of severe heatwaves will rise by 30-times the current climate by the end -21st century.
