Scientists say Europe's heatwave was virtually impossible without climate change

• Of more than 800 European cities analyzed, 45% have recorded or are forecast to record their highest heat stress levels for late June, with parts of France experiencing overnight temperatures above 20°C for more than a week
• A comparable heatwave in June 1976 would have been approximately 3.5°C cooler than the current event, demonstrating rapid warming over just a few decades
• Britain recorded a record-high temperature for June, and the heatwave has killed dozens, disrupted power supplies, and forced closures of schools and cultural landmarks across Western Europe

Market Summary: Europe Heatwave Linked to Climate Change

Key Findings:

Scientists from the World Weather Attribution (WWA) group determined that the record-breaking Western European heatwave would have been "virtually impossible" without human-caused climate change. The analysis found that soaring night-time temperatures are now 100 times more likely than they were just two decades ago.

Critical Data Points:

• A comparable June 1976 heatwave would have been approximately 3.5°C cooler than current conditions
• 45% of over 800 analyzed European cities have recorded or are forecast to record their highest heat stress levels for late June
• Britain set a new June temperature record on Thursday
• Previous European heat events caused over 60,000 heat-related deaths in 2022
• Global temperatures have increased approximately 1.4°C above pre-industrial levels
• Parts of France experienced overnight temperatures above 20°C for over a week, with some nights reaching nearly 30°C

Market and Sector Implications:

The extreme weather has disrupted power supplies and forced closures of schools and cultural landmarks across the region. The findings underscore escalating climate risks for European infrastructure, energy systems, and public health services.

Key Context:

Scientists attribute warming to greenhouse gas emissions from burning fossil fuels (coal, oil, and gas). Europe remains the world's fastest-warming continent. The El Niño weather pattern was ruled out as a contributing factor to this specific heatwave.

Researchers warn that without accelerated efforts to slow global warming, record temperatures will be exceeded with increasing frequency, presenting growing risks to public health and economic stability.
