The number of extremely hot days in a year – when the temperature soars past the 50 degrees Celsius mark – has doubled across the world since the 1980s, according to an analysis by BBC which underlined the harsh realities of the global climate crisis. The study says the number of days on which the mercury goes past 50°C has been consistently going up in every subsequent decade since 1980. Between 1980 and 2009, temperatures went past the 50°C mark 14 days per year on average. But between 2010 and 2019, that number shot up to 26 days, the BBC analysis has found. That apart, the temperature mark of 45°C has also witnessed a sharp jump during the same time period, being recorded an extra two weeks per year on average.
