As extreme heat lingers across swathes of Europe, Euroverify looks at the evidence linking human-driven climate change with hotter and more persistent heatwaves.

Recent analysis by climate experts confirms that while heatwaves can occur naturally, human-driven climate change is increasing their frequency, intensity, and duration in Europe. Scientific studies, including a comprehensive review by Carbon Brief, found that 95% of heat-related events in Europe were made more severe or likely due to climate change. 

Europe is particularly vulnerable as it is the fastest warming continent. Additional global warming is expected to further intensify and increase the frequency of heatwaves. Some studies also point to atmospheric phenomena, such as double jet streams, as contributing factors to persistent heatwaves in the region.

What we know about the link between climate change and heatwaves

What is the link between climate change and heatwaves? As parts of Europe continue to swelter in soaring temperatures, we've spoken to climate experts to verify the link between climate change and heatwaves. A heatwave is a prolonged period, usually of at least three days, of much warmer than average weather. The heatwave threshold temperature varies across Europe, for example from 25 degrees Celsius in Helsinki to 39 degrees Celsius in Athens. These thresholds also vary within countries. Scientists do not directly attribute heatwaves to climate change. These episodes can happen regardless of rising global temperatures. But climate change is making heatwaves more frequent, more intense and longer lasting. Researchers at Carbon Brief have mapped every scientific study on how climate change has influenced extreme weather events, such as flooding, drought or heatwaves. These studies cover 116 heat-related events in Europe. Of those, 95% were scientifically deemed to have been made more severe or more likely because of climate change. This is why scientists say episodes of intense heat will probably become the new normal. Additional global warming may further increase the frequency and intensity of heatwaves, and Europe is vulnerable because it's the world's fastest warming continent. Other studies link Europe's heatwaves to double jet streams, which is when a band of very strong air coming from the west splits into two branches, leaving a mass of warm air over Europe.
