Europe’s Climate Crisis: Continent Warming at Twice the Global Rate Amid Record-Breaking Heat Waves

Much of western Europe is experiencing an intense spring heat wave, with unusually hot temperatures stretching from the UK and Ireland in the north through Germany, France, Spain, and Italy.

The unseasonable spring weather is driven by a “heat dome” – a strong, slow-moving high-pressure atmospheric system originating from northern Africa that traps hot air over Europe like a lid on a boiling pot. Such weather systems have become more frequent in Europe over the past 25 years, according to the EU’s Copernicus Climate Change Service, contributing to more regular and extreme heat events.

Why Europe is already experiencing record heat waves

“Temperatures on this scale were once exceptional even at the height of summer,” said Friederike Otto, a professor of climate science at Imperial College London. “This record-breaking heat has the fingerprints of climate change all over it.”

Europe warming twice as fast

While it’s too early to determine how much this latest extreme heat event was intensified by greenhouse gas emissions, previous analyses of six major European heat waves since 2003 by climate scientists at the UK-based World Weather Attribution – which Otto co-founded – show these extreme events were “much more likely and more intense due to human-induced climate change.”

The latest European State of the Climate report, released in April, found that at least 95% of the continent experienced above-average annual temperatures in 2025. Intense heat waves exceeding 30°C were recorded as far north as the Arctic Circle, while sea surface temperatures reached record highs.

“Europe is the fastest-warming continent, and the impacts are already severe,” said Florian Pappenberger, head of the European Centre for Medium-Range Weather Forecasts, one of the agencies behind the report.

Europe is heating at twice the global average rate. Temperatures have risen by 2.5°C (4.3°F) compared with pre-industrial levels of the late 19th century, while global averages show an increase of 1.4°C.

Why is it getting this hot?

This accelerated warming is partly due to geography. Europe is connected to the Arctic, the only other region warming even faster. The average temperature increase around the North Pole has already exceeded 3.3°C, according to Copernicus data. Because darker, ice-free Arctic Ocean absorbs more sunlight than reflective ice, warming accelerates.

This albedo effect is also active across Europe. Areas that were once permanently frozen or snow-covered well into summer, such as high-altitude regions of the Alps, are now increasingly snow-free. With darker ground reflecting less solar radiation back into space, warming has intensified.

Wavering winds shifting weather patterns

Scientists have also linked Europe’s warming to shifting jet stream winds – the high-altitude river of air flowing toward Europe from the west. Once relatively stable, these winds have been disrupted by climate change, leading to more extreme weather patterns that persist longer.

A 2022 study led by Efi Rousi, then a postdoctoral researcher at the Potsdam Institute for Climate Impact Research in Germany, found that periods when the jet stream splits into two branches have increased. This results in more heat waves across Europe, particularly in the west.

“In this region, which coincides with the exit of the storm track coming from the North Atlantic towards Europe, weather systems normally originate from the Atlantic and therefore have a cooling effect,” Rousi explained. “During double jet states, weather systems get diverted northwards and persistent heatwaves can develop over western Europe.”

Cleaner air warming the planet

Paradoxically, efforts to tackle air pollution may have contributed to increased warming in Europe. The 2025 European State of the Climate report noted that stricter air quality regulations since the 1980s have reduced pollution but are now responsible for warmer temperatures.

Before clean air rules took effect, tiny reflective sulfate and nitrate particles from vehicle exhaust and factory smokestacks helped cool the continent by reflecting sunlight, indirectly offsetting some of the warming caused by increased greenhouse gases.

Climate scientists emphasize that this doesn’t mean abandoning emission reduction efforts. The need to minimize warming was highlighted in a new report from the UN’s World Meteorological Agency and the UK’s Met Office, which forecasts near-record global temperatures in the next five years and predicts a new hottest-ever year before 2031.

“The task ahead is clear,” said UN Secretary-General Antonio Guterres, calling for efforts to minimize temperature rise to “build a safer, fairer, and more resilient future for all.”

Last week, the UN voted to continue supporting a “rapid, just, and equitable transition away from fossil fuels.” Meanwhile, the rapid rollout of renewable energy since 2000 has already shifted warming trends away from the worst-case scenario.
