The 2025 climate report puts a sustained run of heat in perspective

Copernicus reported on 14 January 2026 that 2025 was the third-warmest year in its global record. It was only 0.01°C cooler than 2023 and 0.13°C cooler than 2024, according to the official annual findings.

The ranking is only part of the story

Reuters reported that the World Meteorological Organization’s eight datasets all placed 2023–2025 as the warmest three years recorded, although they differed slightly on the order. Six ranked 2025 third and two ranked it second. Those small differences reflect methods and measurements, rather than disagreement about the wider heat trend.

Copernicus calculated that the 2023–2025 average exceeded 1.5°C above the pre-industrial reference level. That three-year measure is different from the long-term warming level used for the Paris Agreement target, which is assessed over decades. A short-period crossing should not be presented as proof that the long-term threshold has already been permanently passed.

What useful climate coverage looks like

WDWK’s perspective is that a heat record should lead to practical questions as well as a ranking: how communities prepare for heat, how essential services remain dependable and how emissions are reduced. The data establish the scale of warming. Turning that knowledge into protection requires choices beyond the publication of a report.
