May 2026 Tied for Second Warmest on Record

May 2026 was the second warmest May documented globally, according to Copernicus data. The month’s global air temperatures registered 1.42°C above pre-industrial levels, signaling a significant warming trend.

Sea surface temperatures also approached near-record highs, indicating widespread oceanic heat accumulation. These findings align with observations of Europe’s early and intense heatwave experienced during the month.

The data suggests a strong link between these temperature anomalies and a rapidly warming climate. Furthermore, the conditions are consistent with the likely development of an El Niño event in the Pacific Ocean.

This combination of factors contributed to widespread drought conditions observed in various regions. The report highlights the ongoing impact of climate change on global weather patterns.
