Global climate predictions show temperatures are expected to continue at or near record levels in the next five years, increasing climate risks and impacts on societies, economies and sustainable development, according to a new report from the World Meteorological Organization (WMO).
The WMO report forecasts that the annually averaged global mean near-surface temperature for each year between 2025 and 2029 is predicted to be between 1.2°C and 1.9°C higher than the average over the years 1850-1900.
There is an 80% chance that at least one year between 2025 and 2029 will be warmer than the warmest year on record (currently 2024). And there is an 86% chance that at least one year will be more than 1.5°C above the pre-industrial level. The report does not give global predictions for individual years.
There is a forecast 70% chance that the five-year average warming for 2025-2029 will be more than 1.5°C, according to the report. This is up from 47% in last year's report (for the 2024-2028 period) and up from 32% in the 2023 report for the 2023-2027 period.
Every additional fraction of a degree of warming drives more harmful heatwaves, extreme rainfall events, intense droughts, melting of ice sheets, sea ice, and glaciers, heating of the ocean, and rising sea levels.
