"Heatwaves will become so extreme in certain regions of the world within 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 events triggering "large-scale suffering and loss of life", the organisations said.
Heatwave catastrophes this year in countries like Somalia and Pakistan foreshadow a future with deadlier, more frequent, and more intense heat-related humanitarian emergencies, they warned in a joint report.
The UN's Office for the Coordination of Humanitarian Affairs (OCHA) and the International Federation of Red Cross and Red Crescent Societies (IFRC) released the report in advance of next month's UN's COP27 climate change summit in Egypt."
