In 2015, the projected date for reaching 1.5°C above pre-industrial levels was 2042, based on ERA5 data. Today, our C3S global temperature-trend-monitor anticipates the threshold breach within this decade.

2026 is on track to be one of 4 warmest years on record, marked by exceptional global temperatures, melting ice, rising sea levels, and a very strong El Niño that will unleash more heat & extreme weather into 2027.

🌡 The latest C3S Climate Bulletin reports that 2026 is virtually certain (>99%) to exceed 1.5°C above pre-industrial levels. Global and sea surface temperature were both record high for the month.

💧 C3S Climate Bulletin reports dry conditions and exceptionally low river flows across much of central and eastern Europe. Low flows affected major rivers including the Danube, Vistula & Rhine. Wetter-than-average conditions and heavy rainfall affected several other regions.

Greenhouse gas levels hit new record highs, locking in more long-term temperature increase.
The intensifying El Niño may lead to a further surge.

The chance to keep global warming below 1.5°C with no overshoot is gone.
But urgent action can still limit the overshoot and bring warming back to 1.5°C by 2100.
Current policies, however, put the 🌎 on course for up to 2.8°C this century.

💧 The September C3S Climate Bulletin reports widespread dry conditions across western, central & eastern Europe. Record-low river flows for the month affected the Rhine, Danube, Vistula and Garonne-Dordogne. Late-month rainfall caused flooding in parts of France and Spain.

🌡️ September 2026 was the 2nd warmest globally & 3rd warmest in Europe on record.
🇪🇺 Western Europe saw exceptional heat, with parts of France, Portugal, Spain & Italy 4–6°C above average.

The global #Ocean experienced its hottest summer on record, with average sea surface temperatures hitting 21.01-degrees Celsius.
This surpasses the 2023 record of 20.93-degrees, resulting in 18% of the global ocean experiencing intense #MarineHeatwaves for over 20 days, with 85% of the Equatorial #Pacific seeing above-average temperatures.

🌊 Sea surface temperatures across the central-eastern equatorial Pacific (Niño 3.4 region) are already well above average & are continuing to rise.
As El Niño intensifies, temperature anomalies are expected to reach about +3.6°C in the next 3 months.
