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.

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

[UN Environment Programme @UNEP]

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 latest #EmissionsGap Report from @UNEP warns current climate plans fall dangerously short, putting the world on track for worsening impacts.

@antonioguterres calls for urgent #ClimateAction to cut emissions & accelerate clean energy.

🌡 The latest C3S Climate Bulletin reports September was the 2nd-warmest on record, at 1.63°C above the estimated pre-industrial level. The average sea surface temperature across the extra-polar ocean reached a September record of 21.05°C. https://t.co/hPLo0JxSjT

[Copernicus ECMWF @CopernicusECMWF]

💧 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.

[Copernicus EU @CopernicusEU]

🌡️ 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.

[Copernicus Marine @CMEMS_EU]

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.
