IV drips, cooling centres and gallons of free water are just some of the tactics used to help the homeless survive deadly heat. It's 82F (28C) in Koreatown, Los Angeles, and there's a light breeze – a relief from the triple digit (38C and up) temperatures the neighbourhood can reach during summer. But still, members of the homeless community are unusually lethargic as Ktown for All, a nonprofit delivering aid to unhoused individuals, makes their rounds. Volunteers hand out meals, hygiene packs, bottles of water and the odd tent to people sleeping on the streets, as well as checking in to see how they're coping with the heat. (BBC News)
