Global temperatures could break heat record in next five years
Data also shows small but ‘shocking’ likelihood of year 2C hotter than preindustrial era before 2030
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”.
Coming after the hottest 10 years ever measured, the latest medium-term global climate update highlights the growing threat to human health, national economies and natural landscapes unless people stop burning oil, gas, coal and trees.
The update, which synthesises short-term weather observations and long-term climate projections, said there was a 70% chance that five-year average warming for 2025-2029 will be more than 1.5C above preindustrial levels.

The Met Office’s Leon Hermanson, who led the production of the report, said 2025 is likely to be one of the three warmest years on record.
Chris Hewitt, director of climate services at the WMO, described a “worrying picture” for heatwaves and human health. However, he said it was still not too late to limit warming if fossil fuel emissions are cut.
