Heatwaves will make entire regions uninhabitable within decades, UN warns

Climate Change: Heatwaves are predicted to "exceed human physiological and social limits" in the Sahel, the Horn of Africa and south and southwest Asia.

Heatwaves will become so extreme in certain regions of the world within the coming decades that human life there will be unsustainable, the United Nations and the Red Cross said Monday.

Heatwaves are predicted to "exceed human physiological and social limits" in the Sahel, the Horn of Africa and south and southwest Asia, with extreme heatwaves triggering "large-scale suffering and loss of life", the organisations said.
