At least 2,200 Indians this summer have died in a heat wave, making it the deadliest heat wave in the country, reports Quartz. Those most vulnerable are children and the elderly, because their body regulation systems are the weakest.
According to the article, sudden changes in temperatures will remain deadly. The 2003 heat wave in Europe killed about 80,000 people. After the 2003 heat wave, France adopted a warning system and in the 2006 heat wave, it is estimated that the system prevented as many as 4,400 deaths. Since then Australia and the UK have adopted such systems too. In India, only Ahmedabad has such a system.
