European heatwave slashes grain harvest by €2 billion

A record June 2026 heatwave swept across Europe, reducing the forecast grain harvest by roughly 9‑10 million tonnes. The Energy and Climate Intelligence Unit estimates the loss in value at about €2 billion (£1.7 billion). France and Hungary were hardest hit, with production cuts worth €891 million and €444 million respectively, while Spain, Germany and other states also saw sizable declines. The EU's corn forecast was cut from 57.2 Mt to 52.7 Mt, prompting concerns that imports from Ukraine and Brazil may rise to fill the shortfall.

The same extreme temperatures hit the United Kingdom, where a Grantham Institute and CMCC survey found workers lost an average of 0.47 hours per day during the peak week. The resulting productivity loss was estimated at over £1 billion (about $1.5 billion). Physically demanding jobs in construction and agriculture saw the greatest hour reductions; 3.6 % of respondents (≈1.25 million people) did not work at all. A majority (87 %) reported heat‑related health effects such as fatigue, dizziness or sleep disruption.

Scientists linked the event to climate change, noting that warmer air increases soil‑moisture evaporation and amplifies drought conditions across the continent, making extreme heat the dominant factor behind the current agricultural shortfall.
