🌡 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. climate.copernicus.eu/surfac…

💧 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.

Climate change is making Ireland increasingly vulnerable to summer drought as higher temperatures draw more moisture from soils and vegetation, new research has found

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.

🚨 It is official: summer 2026 was the hottest summer ever recorded in Western Europe, according to the Copernicus Climate Change Service (C3S)(eu1.hubs.ly/H0y9-bG0)

🌊 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.

🌡 August #C3S Climate Bulletin reports August was joint-warmest month on record & 1.65°C above the estimated pre-industrial level. Western Europe saw its warmest summer on record, while average sea surface temperature across extra-polar ocean was also joint highest on record.⬇️

The math isn't mathing.
The world spends more than three times as much on fossil fuel subsidies as it would cost to transition to clean economies for a safe climate and air.
The solutions are ready and the money is there. What’s needed now is action at scale.
Here’s how: bit.ly/3UFnsYq #CleanAirDay

🌡️ El Niño is firmly established and will intensify into a very strong event in the coming months. WMO forecasts show ~100% likelihood that it will persist through February 2027.
A very strong El Niño ≠ same impacts everywhere.

New report from @UNEP : 'Limiting Overshoot, Navigating exceedance of 1.5°C and pathways towards return’
Details ⬇️
Global warming is set to cross 1.5°C, pushing climate risks and impacts to increasingly dangerous heights, a new UNEP report warns.
Predicted impacts include extreme weather and threats to human health and economies.
Action now can still limit the magnitude and duration of the peak and preserve the possibility of returning to or below 1.5°C through an ‘overshoot, peak, and decline’ pathway

Global temperature rise is set to cross 1.5°C, pushing climate risks & impacts to increasingly dangerous heights, new @UNEP report warns.
But it’s still possible to limit, adapt to & return from higher temperatures if we take urgent #ClimateAction now.
