More than 100 countries now experience at least 10 more “hot days” a year than a decade ago when the Paris climate accord was drawn up, scientists have said, as greenhouse gas emissions failed to be reduced.
The global average temperature rise to 1.3C above the pre-industrial levels from 1C in 2015, as emissions continued to rise, meant almost every country in the world had hotter days, the Climate Central and World Weather Attribution groups of international scientists concluded.
The warming over the decade resulted in an average of at least 30 more “hot days” annually in 10 countries, defined as being where temperatures are warmer for more than 90 per cent of days for the area compared with 1991-2020.
