November 9, 2026 | By Joseph | World Desk
The World Meteorological Organization says 2026 is on course to become one of the four warmest years in the observational record. Its November 9 climate update, released as COP31 opened, reports January–September average surface temperatures about 1.47 degrees Celsius above the 1850–1900 baseline.
What the measurements show
The agency also reports record-high global mean sea level in the satellite era and preliminary indications that ocean heat content has reached a tenth consecutive annual record. A strong El Niño is expected to intensify heat and some weather extremes into 2027.
These figures describe global averages and long-term indicators, not a prediction that every country will experience the same conditions. Local drought, floods and heat depend on regional atmospheric and ocean patterns, exposure and preparedness.
Why the dates and definitions matter
The WMO makes clear its report uses information available through September for several measures. That cutoff matters: the findings should not be presented as a final tally of all 2026 weather. They provide a dated scientific baseline for the climate negotiations now underway.
