There is an 80% chance that global temperatures will break at least one annual heat record in the next five years, raising the risk of extreme droughts, floods and forest fires, a new report by the World Meteorological Organization (WMO) has shown.

For the first time, the data also indicated a small likelihood that before 2030, the world could experience a year that is 2C hotter than the preindustrial era, a possibility scientists described as “shocking”.

In 2024, the 1.5C threshold was breached on an annual basis for the first time – an outcome that was considered implausible in any of the five-year predictions before 2014. Last year was the hottest in the 175-year observational record.
