This forecast follows 2024’s temporary breach of the critical 1.5C threshold, a limit nations agreed upon to avert the most catastrophic impacts of global warming. The WMO and Met Office further predict a 91 per cent chance that at least one year in the coming five will similarly exceed this crucial benchmark. Moreover, there is a 75 per cent likelihood that the average temperature for the entire 2026-2030 five-year period will exceed 1.5C above the 1950-1990 average, according to the scientists.
