In Nigeria, Farouk and Joy both work in extreme heat. Farouk, a well-digger from a rural community in a decertified area, has to dig deeper every year to find water; when it's 43°C on the surface, temperatures down the well-shaft are even hotter. In the Niger Delta, Joy makes a living by braving temperatures of 90°C caused by illegal gas flares. With 2021 set to be one of the hottest years on Earth, Life at 50°C explores the human impact of climate change.
