Parya, 42, a labourer, works in the sun during a heatwave at a brick kiln factory, in Jacobabad, Pakistan, May 14, 2022. Jacobabad's roughly 200,000 residents are well aware of their reputation as one of the world's hottest cities. "If we go to hell, we'll take a blanket," is a common joke told in the area. Few places are more punishing. Last month, temperatures hit 51 Celsius (124 Fahrenheit) on May 14, which local meteorological officials was highly unusual for that time of year.
