Severe weather events, exacerbated by anthropogenic emissions, are already having devastating impacts on people who live in urban areas, and on the infrastructure that supports these communities and those of many other distant places  . Between 2000 and 2015, the global population in locations that were affected by floods grew by 58-86 million . The direct economic costs of all extreme events reached USD 210-268 billion in 2020  or about USD 0.7 billion d'1; this figure does not include knock-on costs in supply chains or days off work lost so that the actual economic costs could be far higher. Depending on RCP, between half  and three-quarters  of the global population could be exposed to periods of life-threatening climatic conditions arising from coupled impacts of extreme heat and humidity by 2100 .
