Per World Weather Attribution, scientists found that the European heatwave is producing temperatures that would be "virtually impossible" in June 50 years ago. Even in 2003, when a heatwave in Europe killed ~70,000, these temps would be ten times less likely to occur.

Global warming is making extreme heat more likely and more severe.
This is getting ridiculous.
Germany has preliminarily set a new all-time heat record with 41.3°C in Saarbrücken. Until this extraordinary heatwave, the country had never recorded a temperature above 40°C in June. More extreme heat is expected this weekend.
