August 2025: A Continued Trend of Global Warming and Extreme Weather
August 2025 marked the third-warmest August on record globally, according to data released by the European Union’s Copernicus Climate Change Service (C3S). This continues a disturbing trend of escalating temperatures and increasingly frequent extreme weather events impacting communities worldwide. Understanding these shifts is crucial for both mitigation and adaptation efforts.
Key global Findings for August 2025:
Global Temperature: 0.49°C above the 1991-2020 average.
Compared to Pre-Industrial Levels: 1.29°C warmer.
Past 12 Months (sept 2024 – Aug 2025): 0.64°C above the 1991-2020 average, and 1.53°C above pre-industrial levels. Summer 2025 (June-August): the third-warmest summer on record, trailing only 2023 and 2024.
While slightly cooler than the record-breaking Augusts of 2023 and 2024 (by 0.22°C), these figures underscore the relentless warming of our planet.You’re witnessing a clear pattern, and the implications are far-reaching.
Europe Experiences Intense Heat and Devastating Wildfires
europe also felt the heat, with August averaging 19.46°C – 0.3°C above average. Though not among the continent’s ten warmest Augusts on record,specific regions faced severe conditions.
Southwest Europe, notably the Iberian Peninsula and southwest France, endured a third major heatwave this summer. This,unluckily,fueled exceptionally destructive wildfires. Samantha Burgess, Strategic Lead for Climate at the European Center for Medium-Range weather Forecasts (ECMWF), highlighted the severity of the situation.
The Scale of the Wildfires:
Europe-wide: Over 1 million hectares burned – an area larger than Cyprus.
Spain: Nearly 400,000 hectares burned as january. Portugal: More than 260,000 hectares burned since january.
These fires weren’t simply a matter of bad luck. A rapid analysis by world Weather Attribution confirmed that climate change significantly increased both the likelihood and intensity of the hot, dry, and windy conditions that fueled them. You can read more about this attribution study here.
Europe experienced its fourth-warmest summer on record, 0.9°C above the 1991-2020 average. Most of the continent saw above-average temperatures, with only parts of Eastern Europe experiencing cooler conditions. Drier-than-average conditions also plagued much of western and southern Europe, the Balkans, the black sea region, and parts of Scandinavia and northwestern Russia.
Warming Oceans Amplify the Crisis
The global picture isn’t limited to land temperatures. Average sea surface temperatures (SST) reached 20.82°C – the third-highest on record. The North Pacific,in particular,experienced significantly above-average SSTs,with some areas reaching record highs.
Burgess emphasizes that these warming oceans, coupled with land-based extremes, underscore the urgent need for both emissions reductions and* adaptation strategies. You need to prepare for a future with more frequent and intense climate events.
european waters presented a mixed picture. While the Mediterranean wasn’t as exceptionally warm as in 2024, record highs persisted in the North Atlantic west of France and the UK. The potential impacts on marine ecosystems are significant, as highlighted by recent research on the Mediterranean here.
