Copernicus says May 2026 was the world’s second-warmest May on record

Copernicus reported that May 2026 was the second-warmest May on record globally.
Copernicus said the global average surface air temperature in May 2026 was 15.81C, which was 0.55C above the 1991-2020 May average and 1.42C above the estimated 1850-1900 preindustrial average.
Western Europe experienced an unusually early and intense heatwave in May, with Copernicus describing a rapid shift from cooler-than-average conditions to one of the strongest heatwaves observed this early in the year in the region.
Temperature records for May were broken in Britain, France, Ireland and Portugal during the heatwave.
Multiple reports said the heat in western Europe was linked to a mass of warm air from North Africa that pushed temperatures well above normal.
Copernicus said the May heat event in Europe is consistent with a broader long-term pattern of rapid warming in Europe and more frequent, more intense, and earlier heatwaves.
Reports on the Copernicus bulletin said average sea-surface temperatures were also the second-highest on record, with especially high temperatures in the tropical and equatorial Pacific.
Several reports said developing El Niño conditions in the equatorial Pacific were continuing and were cited alongside climate change as a factor linked to elevated global temperatures and the risk of further extreme weather in coming months.

How left and right are reading this

Both agree: May 2026’s unusual warmth was not treated as an isolated blip: both framings anchor it in observed records and patterns, including western Europe’s early heatwave and a broader backdrop of elevated global and sea-surface temperatures.
They split on: Less a disagreement than a question of emphasis: whether the month’s heat is most telling as evidence of Europe’s longer-term warming pattern, or as a notable climate signal described cautiously alongside developing El Niño conditions.
