Summary
The World Meteorological Organization confirmed that 2025 ranked among the three warmest years on record; the UN noted a global average surface temperature about 1.44°C above the 1850–1900 average and pointed to continued ocean heat accumulation.
At the briefing, Steph cited the World Meteorological Organization’s consolidated analysis showing 2025 was among the three warmest years on record. She said WMO’s results show a global average surface temperature about 1.44°C above the 1850–1900 average and noted that several datasets ranked 2025 as the second or third warmest year in the observational record.
Steph also referenced a study in Advances in Atmospheric Sciences showing ocean temperatures near record highs, describing these trends as evidence of long‑term heat accumulation in the climate system. She directed reporters to the WMO website for further details and datasets.
