Around a third of the world's population is currently exposed to deadly heat for 20 days or more a year, and without action to reduce greenhouse gas emissions the risk will increase substantially as the world warms, according to a study published in Nature Climate Change. Scientists from the UK and US reviewed papers published between 1980-2014, identifying 783 cases relating to heat deaths from 164 cities in 36 countries, and concluded that, by 2100, around three-quarters of humanity could be exposed to deadly temperatures, but large cuts to emissions could reduce the threat to around half.
