Extreme heat

It is a silent killer that is responsible for more deaths than any other natural disaster.

The headlines coming out of India as it grappled with an extreme heatwave the past few days have been alarming. A weather station in Delhi recorded a temperature of 52.9 degrees Celsius, which, if confirmed, would be a national record. Animals have died, students have fainted at schools and drinking water taps have dried up. A labourer reportedly died of heatstroke last week.
