The whole world is getting hotter as carbon pollution from fossil fuel burning traps ever more heat, but Europe is heating up twice as fast as other continents. The consequences are increasingly deadly, with tens of thousands of heatwave deaths so far this summer.
Why is Europe most affected by global heating?
Land requires less heat than the vast and deep oceans to warm up, so all continents are warming more quickly than the seas. But Europe is particularly vulnerable for four reasons: changed weather patterns, its closeness to the Arctic, less snow and less air pollution.
As a result, Europe is now 2.5C hotter than before the mass burning of fossil fuels, almost double the global average 1.4C rise. Temperatures in Europe have risen by 0.56C a decade since the mid-1990s, compared with 0.42C in North America, 0.36C in Africa and 0.27C in South America.
How have Europe’s weather patterns changed?
Shifts in how the atmosphere circulates over Europe have led to more frequent and more intense summer heatwaves. This includes the worst ever heatwave, in June 2026, in which a vast area of hot air was trapped under a stationary “heat dome”.
Scientists are still investigating the role of global heating in causing changes in atmospheric circulation, but a link seems increasingly likely.
Dr Samantha Burgess, from the EU’s Copernicus Climate Change Service, said: “We see statistically significant changes in surface pressure patterns and other measures of circulation when we look at trends over the last 40 or more years, and on this timescale they are more likely associated with climate change than natural variability.”
The association may be the result of a changing jet stream, a fast high-level wind that has a powerful influence on Europe’s weather and is itself affected by rising temperatures.
Why is the Arctic important?
The Arctic is the fastest warming region on the planet, despite having no land. This is because the white polar ice cap, which normally reflects the vast majority of sunlight back into space, is melting away fast. As a result, the darker ocean exposed by the melting absorbs much more heat, which then melts more ice, forming a vicious circle. With a significant proportion of Europe relatively close to the Arctic, temperatures are therefore rising faster.
What about snow cover?
Most of Europe had snowfall in winter in the past. Like the Arctic sea ice, this snow reflected sunlight and kept the continent cooler. But the climate crisis is shrinking snow-covered areas.
In March 2025, Europe’s blanket of snow was about 1.3m km2, 31% below the 1991-2020 average. That lost area is roughly the area of France, Italy, Germany, Switzerland and Austria combined. It was the third lowest snow cover since records began in 1983.
Why does reduced air pollution affect temperatures?
Air pollution kills millions of people globally every year and so Europe’s record of cutting toxic air levels in recent decades is unequivocally a good thing. However, cleaner air is also unmasking the impact of the rise in carbon dioxide pollution in the atmosphere.
Air pollution particles can reflect the sun’s rays, directly or by seeding the formation of clouds, meaning the heat does not reach the ground. Fewer particles means less reflection and more heat that is trapped by greenhouse gases. Lower pollution might even be connected to the increase in blocking weather patterns.
How important is each of the four factors above?
The short answer is that scientists don’t yet know, but they aim to have an estimate next year.
Burgess said: “What we can say is that the importance of each factor must vary with season, with proximity to the Arctic important in autumn and winter, and circulation changes since the late 1970s of greater statistical significance in summer.”
The drop in air pollution is most marked in winter because of declining coal heating in homes, and snow cover is a winter issue. Winter warming in Europe in recent decades has been strongest in the north, while summer warming has been strongest in the south-east.
What are the consequences?
The rapid heating is leading to ever more deaths and more intense wildfires and droughts. Storms, intense rainfall and floods are also being supercharged by the extra heat in the climate system. All deeply affect lives and livelihoods across the continent and will continue to worsen until emissions reach net zero. Rapid cuts in CO2 pollution and the rollout of measures to protect citizens are urgently needed.
The UN climate chief, Simon Stiell, said in late July: “The awful costs of this climate crisis – both human and economic – are now reaching national emergency levels. What needs to be done is clear: leave coal, oil and gas behind faster, scale up renewables, and protect people.”
