The latest European State of the Climate report, published by the Copernicus Climate Change Service (C3S) and the World Meteorological Organization (WMO), delivers an unambiguous verdict: climate change is no longer a distant threat but a present-day crisis reshaping Europe's food production, public health, and economic stability.
According to the report, at least 95% of the continent recorded above-average temperatures in 2025. The United Kingdom, Norway, and Iceland each experienced their hottest year on record. In the Arctic Circle, thermometers hit 30°C, while southern and eastern Spain endured 50 additional days of 'heat stress' — when the perceived temperature reaches 32°C or higher. Türkiye recorded 50°C for the first time, and 85% of Greece faced temperatures near or above 40°C, peaking at 44°C.
Sub-Arctic Fennoscandia — encompassing northern Norway, Sweden, and Finland — suffered its longest and most severe heatwave on record in July, with temperatures spiking at 34.9°C. These extremes are not isolated events but part of a broader trend: Europe is warming more than twice as fast as the global average, with temperatures now approximately 2.5°C above pre-industrial levels.
Vanishing Winters and Melting Ice
The report highlights a dramatic reduction in cold weather across Europe. The area experiencing winter days with freezing temperatures is shrinking, and in 2025 it fell below the 1991–2020 average. Glaciers across the continent continue to melt at alarming rates, with Iceland recording its second-largest ice loss on record. Snow cover at the end of March was 1.32 million square kilometres below average — roughly the combined size of Austria, France, Germany, Italy, and Switzerland.
Perhaps the most sobering data comes from the Greenland Ice Sheet, which lost 139 gigatonnes of ice in 2025 — equivalent to about 1.5 times the ice stored in all the glaciers of the European Alps, or enough to fill more than 55 million Olympic-sized swimming pools. The Greenland Ice Sheet covers approximately 80% of Greenland and holds enough water to raise global sea levels by over seven metres. It is currently the largest single source of global sea-level rise, contributing about 20% of the total.
The rapid warming is driven in part by 'Arctic amplification', a feedback loop in which melting snow and ice expose darker surfaces that absorb more heat, accelerating further melting. This process also affects snowy regions like the Alps. Additionally, Europe's success in reducing air pollution — while beneficial for health — has inadvertently reduced the cooling effect of low-level clouds produced by aerosols.
Extreme Weather Intensifies
Climate extremes are becoming more frequent and severe. In 2025, wildfires burned over one million hectares of land across Europe — the largest area on record. Drought conditions affected more than half the continent, leaving 70% of Europe's rivers with below-average annual flow, threatening water security for agriculture, industry, and households. Marine heatwaves impacted 86% of Europe's oceans, with the Mediterranean and Norwegian seas experiencing the most severe conditions, disrupting marine ecosystems and fisheries.
“The pace of climate change demands more urgent action. With rising temperatures, widespread wildfires, and drought, the evidence is unequivocal; climate change is not a future threat, it is our present reality,” said Samantha Burgess, Strategic Lead for Climate at ECMWF.
The report underscores the interconnectedness of climate and biodiversity. The European Biodiversity Strategy 2030 aims to protect and restore natural habitats across the EU. By the end of 2025, roughly half of the strategy's recommended actions were either in place or completed, with many more underway.
Renewable Energy Offers a Glimmer of Hope
Amid the grim findings, there is a notable bright spot: Europe's renewable energy sector is expanding rapidly. In 2025, renewables supplied nearly half of the continent's electricity (46.4%), with solar power setting a new record at 12.5% of the total. This progress is critical for reducing dependency on fossil fuels and cutting greenhouse gas emissions. Countries like Spain, France, and Portugal are racing to expand their renewable capacity, a trend that aligns with the EU's broader energy strategy.
“Maintaining our own state-of-the-art, reliable data records of our Earth system is vital for making informed policy decisions in our rapidly changing climate… [helping] us preserve our sovereignty, our environment, food systems, safety, and economy,” said Mauro Facchini, Head of the Copernicus Unit at the European Commission.
The report serves as a stark reminder that Europe's climate crisis is already exacting a heavy toll on food production, public health, and economic stability. Without accelerated action, the continent's ability to adapt will be severely tested. As European leaders debate measures like reviving Eurobonds to fund energy transitions, the data from Copernicus makes clear that the window for meaningful intervention is narrowing.
