What Happened
- February 2026 was recorded as one of the five warmest Februaries globally on record, according to data from the Copernicus Climate Change Service (C3S), the European Union's climate monitoring programme.
- The average global surface air temperature for February 2026 reached 13.26°C, which was well above the long-term February average and approximately 1.49°C above pre-industrial levels (defined as the 1850-1900 baseline).
- This continues a sustained streak of months with global temperatures significantly exceeding pre-industrial baselines — a trend that has persisted since 2023.
- The 1.49°C anomaly is dangerously close to the 1.5°C threshold set by the Paris Agreement as the aspirational upper limit for global warming.
- The year 2025 was recorded as the third warmest year on record globally, while 2024 was the warmest year ever recorded and the first calendar year to breach the 1.5°C threshold for a full year.

Copernicus Climate Change Service (C3S) — What It Is and Why It Matters
The Copernicus Climate Change Service (C3S) is the European Union's official climate monitoring and data service, implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF) on behalf of the European Commission. C3S produces the ERA5 reanalysis dataset — one of the world's most comprehensive climate data products — which reconstructs global climate variables (temperature, precipitation, wind, humidity) from 1940 to the present using satellite data, weather station records, and ocean buoy measurements. C3S monthly climate bulletins are among the most authoritative and widely cited global temperature records. They are used by the UNFCCC, IPCC, and governments worldwide to track compliance with the Paris Agreement.
- C3S: EU climate monitoring service; implemented by ECMWF (Reading, UK)
- ERA5: global climate reanalysis dataset, covers 1940–present, released monthly
- Pre-industrial baseline used by C3S: 1850-1900 period average (consistent with IPCC)
- Other major global temperature tracking agencies: NASA GISS, NOAA NCEI, Met Office (UK), Berkeley Earth
- C3S monthly reports: used by UNFCCC, IPCC, and policy-makers worldwide as reference temperature data
Connection to this news: The C3S report declaring February 2026 as one of the five warmest Februaries on record provides authoritative, scientifically validated data that governments use to assess the pace of climate change and the urgency of mitigation action.
Paris Agreement and the 1.5°C Temperature Threshold
The Paris Agreement, adopted at COP21 in Paris on December 12, 2015, and entered into force on November 4, 2016, is a landmark international climate treaty under the UNFCCC. It established the global goal of limiting the long-term increase in average global temperature to "well below 2°C above pre-industrial levels," with efforts to limit the increase to 1.5°C. The pre-industrial reference period is 1850-1900. The 1.5°C threshold is significant because IPCC's 2018 Special Report on Global Warming of 1.5°C (SR15) found that limiting warming to 1.5°C — rather than 2°C — dramatically reduces risks including sea level rise, extreme weather events, coral reef die-off, and food and water security threats. The threshold refers to a long-term sustained anomaly, not individual months or years.
- Paris Agreement: adopted COP21, December 12, 2015; in force November 4, 2016
- Temperature goal: "well below 2°C," with efforts to limit to 1.5°C above pre-industrial levels
- Pre-industrial baseline: 1850-1900 (as used by IPCC and C3S)
- IPCC SR15 (2018): at 2°C vs 1.5°C, risks of extreme heat, sea level rise, and coral bleaching increase dramatically
- 2024: first full calendar year where average temperature exceeded 1.5°C above pre-industrial levels
- 1.5°C threshold applies to long-term (20-year) sustained anomaly — individual warm months/years alone do not constitute "breaching" the threshold
Connection to this news: February 2026's 1.49°C anomaly, coming after 2024's first full-year breach of 1.5°C, signals that the Paris Agreement's aspirational limit is being approached or periodically exceeded in practice — raising urgent questions about the adequacy of current Nationally Determined Contributions (NDCs).
Global Warming Trends — El Niño, La Niña, and Long-Term Climate Signals
Short-term global temperature variability is significantly influenced by the El Niño-Southern Oscillation (ENSO) — a natural climate pattern in the tropical Pacific Ocean. El Niño events (warming of the central and eastern Pacific) tend to raise global average temperatures, while La Niña events (cooling of the Pacific) have a moderating effect. The record warmth of 2023 and 2024 was partly driven by an exceptionally strong El Niño. By 2025, a weak La Niña emerged, yet global temperatures remained well above historical averages — indicating that the long-term anthropogenic warming signal now dominates over natural variability. February 2026's continued warmth, despite La Niña conditions, underscores that the underlying warming trend is structural rather than cyclical.
- El Niño: warming of central/eastern Pacific → raises global temperatures; La Niña: cooling → moderating effect
- 2023-24 El Niño: exceptionally strong; contributed to record global temperatures in 2023 and 2024
- 2025: transition to weak La Niña — yet temperatures remained 3rd warmest year on record
- Long-term global warming: driven by anthropogenic greenhouse gas (GHG) accumulation — CO2 currently ~425 ppm (far above pre-industrial ~280 ppm)
- Global average temperature trend: approximately +0.2°C per decade since 1980
- Significance of 2026 data: continued warmth under La Niña conditions confirms structural (not just cyclical) warming
Connection to this news: February 2026's position among the five warmest Februaries on record, occurring during a La Niña period, confirms that human-induced climate change is outpacing the cooling influence of natural variability cycles — intensifying pressure on governments to accelerate decarbonisation.
