Europe's Scorched Landscapes Seen from Space After Summer Heatwaves
Satellite images show the impact of Europe's extreme temperatures on its landscapes, including shrunken glaciers, scorched areas from wildfires, and lower river levels.

Europe's heatwaves have left a lasting impact on its landscapes, with satellite images revealing shrunken glaciers, scorched areas from wildfires, and lower river levels. Climate change is making hot spells more likely and intense.
Imagine Europe's landscapes as a big, beautiful painting. But this summer, the heatwaves have come and gone, leaving behind a scorched and dry landscape. It's like someone took a big eraser and rubbed out all the green and blue, leaving only brown and gray. The rivers are running dry, the glaciers are melting, and the wildfires are burning out of control. It's a big problem, and we need to take action to stop it.
Analysis
Europe's Hottest Summer on Record
The summer of 2026 has been one of the hottest on record for western Europe, with temperatures soaring to unprecedented levels. The heatwaves have had a profound impact on the continent's landscapes, with satellite images revealing the extent of the damage.
The impact of the heat has been noticeable in satellite imagery, with shrunken glaciers, scorched areas left by wildfires, and lower river levels. The Palace of Versailles, south of the French capital Paris, appears as an island of trees surrounded by brown fields in these images.
The EU's climate monitoring service, Copernicus, has confirmed that western Europe experienced its hottest June-to-July period on record. The immediate cause of the heatwaves has been persistent high-pressure weather systems bringing clear, sunny skies and allowing temperatures to build, according to the Met Office.
However, climate change, mainly due to the burning of fossil fuels, has been raising average temperatures for decades and making hot spells much more likely and intense. The article highlights the devastating effects of climate change on Europe's landscapes, emphasizing the need for urgent action to mitigate its impact.
Rivers Run Drier
The waters of the Danube, Europe's second-longest river, have dropped to their lowest levels for 30 years in several countries. This has led to unusual discoveries on the river bed, including the bones of a mammoth in Bulgaria and a sunken WW2 warship in Serbia.
You can see the sunken ship has emerged from the deep in the right-hand image below. And where the river snakes through Hungary and Romania, nuclear power stations have been forced to shut down or run at reduced capacity for some time because of an inability to use river water for cooling.
Retreating Glaciers in the Alps
Even the snow-capped peaks of the Alps have not escaped the heat. Ongoing measurements suggest this summer could become one of the worst ever recorded for melting Alpine glaciers, with more than a month of the season still to go.
After a mild winter, glaciers had less snow cover than usual at the end of April - and an unusually early heatwave the following month accelerated the melting of snow. This exposed the ice beneath, leaving the glaciers vulnerable to melting faster in subsequent heatwaves.
As you can see below, satellite imagery suggests much of the front of Rhône Glacier in Switzerland has retreated by 50m (160ft) or more since the same time last year. In a stable climate, glaciers would be expected to remain more or less the same size over the long-term.
Wildfires Turn Landscapes Brown
Wildfires have transformed parts of western Europe this summer, too. More than 90,000 hectares (900 sq km or 350 sq miles) has burned in France. This is already its worst year on record, according to the European Forest Fire Information System.
The largest fire in Gironde region, where the city of Bordeaux is situated, burnt about 42,000 hectares of land - roughly equivalent in size to the Isle of Wight. Part of the reason this year has been particularly bad for wildfires is that land has been tinder-dry.
Dr Douglas Kelley of the UK Centre for Ecology and Hydrology tells us extreme wildfires are becoming 'more and more frequent' as climate change is creating ideal conditions, with higher temperatures drying out vegetation and soils faster.
Even zoomed-out satellite imagery of western France shows a striking increase in the browning of land compared to last year. To assess whether 2026 is unusual we used the Normalised Difference Vegetation Index (NDVI), a measure which uses satellite data to assess how green and healthy vegetation is.
Lower readings indicate more sparse or stressed vegetation. The NDVI this summer came in below a five-year benchmark of 2021 to 2025 across about 70% of France. Close to half the UK and roughly 40% of western Germany showed the same.
Prof Andrew Challinor, from the University of Leeds, said the images were 'consistent with widespread water stress', which 'does not bode well' given much of Europe's land is covered by crops meaning it could hit the agriculture industry and food production.
In the worst-affected areas, soil moisture is lower than on about 98% of comparable dates in the historical record, according to Prof Luis Samaniego, from the Helmholtz Centre for Environmental Research.
And, he warns, even if rain returns, some of the agricultural damage may already have been done.
Key points
- Europe's summer heatwaves have left a lasting impact on its landscapes.
- Satellite images reveal shrunken glaciers, scorched areas from wildfires, and lower river levels.
- Climate change is making hot spells more likely and intense.
- The EU's climate monitoring service has confirmed that western Europe experienced its hottest June-to-July period on record.
- The heatwaves have had a profound impact on the continent's agriculture, with widespread water stress and soil moisture levels at historic lows.
There is hope for Europe's landscapes. By taking action to reduce greenhouse gas emissions and adapt to the changing climate, we can mitigate the worst effects of climate change. Governments, businesses, and individuals can all play a role in reducing our carbon footprint and protecting the environment.
If we don't take action to address climate change, the consequences will be severe. Rising temperatures will continue to melt glaciers, dry out rivers, and fuel wildfires. The impact on agriculture, food production, and human health will be devastating. We must act now to prevent the worst effects of climate change.
