The world is warming despite natural fluctuations from the El Niño cycle— In 2025, the world was around 1.4 °C warmer than it was in pre-industrial times. But temperatures haven’t increased linearly; there have been spikes and dips along the way.

Line chart of monthly global average land–sea surface temperature anomalies relative to the 1991 to 2020 average, where the series from January 1950 to March 2026 shows a clear upward trend and recent "cool" (La Niña) periods are still warmer than many past "warm" (El Niño) peaks. The chart specifically highlights that this year's La Niña phase is hotter than the warm El Niño phase in 2007 and shows neutral periods between phases.

How confident should we be in a prediction of El Niño? Seasonal forecasts show an emerging warm ENSO signal, but predictability remains low during the spring barrier. Read our blog diving deeper into how to interpret our ENSO-related seasonal forecasts ➡️ www.ecmwf.int/en/about/med...

Global sea surface temperatures continue to cool off as we head into La Nina. 2025 (for the 1st time in 3 years) will not set a new global temperature record. It's the steady longer-term warming that is cause for concern. It will continue until human carbon emissions cease. Truth is bad enough.
