Heatwaves and wildfires across Europe: deadly impacts and climate change attribution

A series of intense heatwaves across Europe in May and June 2026 have led to significant loss of life and widespread wildfires. New research from Imperial College London, the Met Office, and the London School of Hygiene and Tropical Medicine estimated that heatwaves caused 2,700 excess deaths in England and Wales, with London and the South East accounting for over 1,000 of those fatalities. The study attributed a substantial portion of these deaths to climate change. Simultaneously, wildfires near Paris forced evacuations, disrupted transport, and burned over 800 hectares of forest. French authorities mobilised waterbombing planes and hundreds of firefighters to contain the blazes, which were described as 'very virulent' and 'exceptional' in scale. Both events were linked by scientists to human-induced global warming, which is making extreme heat events more frequent and severe.

Key Facts

  • Heatwaves in May and June 2026 caused an estimated 2,700 excess deaths in England and Wales, with over 1,000 in London and the South East.
  • 60% of heat-related deaths in London in May were attributed to climate change by Imperial College researchers.
  • Wildfires near Fontainebleau, 60 km southeast of Paris, burned over 800 hectares, forcing home evacuations and disrupting train and motorway traffic.
  • France dispatched two waterbombing planes from the south of France to fight the Paris-region fires for the first time, indicating exceptional fire danger.
  • The World Weather Attribution group stated that the recent heatwaves would have been 'virtually impossible' without climate change.

Coverage of wildfires near Paris causing evacuations and transport disruption, linked to heatwave and climate change

Al Jazeera reports on wildfires in the Fontainebleau forest, describing their scale and the response by authorities. It notes that this is the first time firefighting planes have been sent from southern France to the Paris region, and quotes scientists linking the heatwave to climate change.

Carbon BriefConcernedLeft

Broader roundup of European heatwave and wildfire impacts, including excess deaths in France and Germany, and climate context

Carbon Brief's DeBriefed newsletter summarises the week's climate news, noting that Western Europe experienced its hottest June on record, with 10,000 evacuated in southern France due to wildfires, and over 2,700 heat-related deaths in France alone. It also references similar excess deaths in Germany and the US.

Focus on heatwave death toll in London and South East, with climate change attribution

The Evening Standard reports on a study estimating over 1,000 heat-related deaths in London and the South East during May and June. It highlights that a majority of these deaths are attributable to climate change and stresses the danger of heatwaves, urging adaptation and emissions cuts.

Conclusion

The European heatwaves and wildfires of 2026 highlight the deadly and disruptive consequences of a warming climate. While the geographic focus differs—urban heat-related mortality in the UK versus rural wildfire evacuations in France—the underlying driver is the same: climate change. The coverage from multiple outlets underscores the urgency of both adaptation measures to protect vulnerable populations and aggressive emissions reductions to mitigate future extremes. The events serve as a stark warning that Europe must prepare for increasingly dangerous summers.

Logical analysis

What sources agree on

  • Heatwaves and wildfires in Europe are linked to human-induced climate change.
  • The extreme heat caused significant loss of life and infrastructure disruption.
  • Authorities and researchers are calling for urgent adaptation and emissions reductions.
