Delhi is sweltering through another summer of extreme heat, with top daytime readings consistently reaching 43C and even minimum temperatures hovering around 32.4C (90.3F).Last week the city endured its warmest May night in 14 years. As government heat alerts follow one after another and people retreat indoors, more than 300,000 individuals living on the city’s streets remain out in the punishing heat.Homeless people are among the most vulnerable to climate extremes, says Chandni Singh, a lead author with the Intergovernmental Panel on Climate Change (IPCC). “Beyond exposure alone, homelessness is often accompanied by unreliable access to food, water and healthcare – all of which are essential to cope with and adapt to extreme heat,” she says.The consequences are deadly. During Delhi’s heatwave last summer, at least 192 homeless people died over a nine-day period, according to a report by the Centre for Holistic Development.Shahida has lived through these realities for almost her entire 20 years. Sitting beneath a Delhi flyover, where her family sleeps on the pavement under pop-up mosquito nets, she says she dreads summer’s arrival. “It severely stresses me out even thinking about summers coming,” she says.
