May 2026 was the second-warmest May on record, marking another alarming milestone in global climate trends, with the planet experiencing its second-hottest May since records began, according to the European Union’s Copernicus Climate Change Service (C3S). Global average temperatures last month were approximately 1.42°C above pre-industrial levels, keeping Earth dangerously close to the 1.5°C Paris Agreement threshold that scientists warn is critical to avoid more severe climate impacts.

The report highlights that only May 2024 was warmer, making 2026 the second-highest recorded May globally.

Global Temperature Snapshot

Copernicus data shows persistent warming trends driven by long-term greenhouse gas emissions, with May 2026 continuing a pattern of record-breaking or near-record temperatures in recent years.

The data indicate that global temperatures are consistently remaining near or above critical climate thresholds.

Europe Faces Early-Season Heatwave

Western Europe experienced one of its most intense early-season heatwaves, with countries including the UK, France, Ireland, and Portugal recording unusually high temperatures for May. Scientists attribute the event to a powerful “heat dome” that pushed hot air from North Africa into Europe.

• Severe early-season heatwave across Western Europe
• Heat dome system intensified temperature extremes
• Increased pressure on energy and water systems
• Rising concerns over drought and wildfire risks

Scientists note that Europe is warming faster than most other regions globally due to climate change patterns.

Climate Drivers Behind the Warming

Experts say the extreme temperatures are not isolated events but part of a broader climate shift. Rising ocean temperatures in the Pacific also suggest the potential development of El Niño conditions, which typically amplify global heat.

El Niño forms when trade winds weaken, allowing warm water to accumulate in the eastern Pacific. This naturally occurring cycle often increases global temperatures and disrupts rainfall patterns across continents.

• Developing El Niño conditions observed in the Pacific Ocean
• Warmer ocean surfaces contribute to global heat
• Increased risk of extreme weather events worldwide
• Interaction with human-driven warming intensifies impacts

Scientists warn that the combination of El Niño and climate change can significantly increase global weather volatility.

Extreme Weather Events Intensify

Alongside rising temperatures, May 2026 also saw multiple extreme weather events across the globe. Flooding affected parts of China and Turkey, while Europe experienced widespread heat stress, highlighting the growing instability of global climate systems.

These events reinforce concerns that climate extremes are becoming more frequent, more intense, and more disruptive to daily life.

A Warming World Near Critical Limits

May 2026 being the second-warmest May on record highlights how fast global temperatures are rising. The planet is now consistently nearing critical climate thresholds, increasing the risk of more frequent and intense extreme weather events.

With El Niño conditions potentially strengthening and emissions still driving warming, scientists warn that climate extremes are becoming a regular global reality rather than rare events.
