Counting the cost of Europe’s summer of fire, drought and lost harvests

Europe's scorching heatwaves are wreaking havoc beyond the discomfort of soaring temperatures. The continent, unaccustomed to such intense heat, is facing severe economic and social consequences. In summer 2026, crops are failing, livestock farmers are using winter feed early, and workers are becoming less productive. Tourism is also being affected as people avoid the extreme heat.

Heat records are being broken, and the economic impact could be significant, with some estimates suggesting a 1 percent drop in the EU's GDP, equivalent to €180 billion. The loss in agricultural output could reach up to 7 percent. Beyond farms, heat disrupts infrastructure, with the Rhine river in Germany so low that large barges cannot navigate.

The UK, however, continues to grow economically, but the heat is already reducing activity. Research estimates that this summer's five heatwaves have cost at least £4.4 billion in lost output, while European economies suffer a 3 percent fall in output per hour for every degree Celsius above 30°C. Farmers like Stephen Eales in Sussex are witnessing the crisis up close, with his wheat yield down 23 percent and oats down 61 percent despite only 11 percent of normal rainfall since March.

The cost of producing his crops has skyrocketed, with fertiliser prices up 15 percent and diesel prices up 86 percent. He anticipates a government carbon tax next year, adding another £17,000 to his expenses. The severe heat arrived just as wheat filled its grains, stopping their growth entirely. Lower yields, disrupted infrastructure, and rising costs paint a grim picture of Europe's summer of fire, drought, and lost harvests.
