A scientific analysis has found that extreme heat amplified by the climate crisis is significantly worsening drought conditions across Europe during summer months. The research, conducted by the World Weather Attribution consortium, examined drought in western Europe from April to June and across 15 eastern European nations over the preceding 12 months. The study determined that atmospheric conditions driven by climate change made heat-induced evaporation 80 times more likely in western Europe and 40 times more likely in eastern Europe. The resulting soil dryness was found to be five times more probable in the west and 11 times more probable in the east compared to conditions in a world without fossil fuel pollution.
Drought in Europe has traditionally been attributed to insufficient rainfall, yet the recent drought in western Europe occurred despite above-average winter precipitation. Scientists indicated that climate change is fundamentally altering the nature of European drought, with elevated temperatures now serving as the primary driver. Current drought conditions classified as extreme would have been categorized as moderate before global heating became prevalent. The drought assessment was completed at the end of June, early in the summer season, yet impacts were already substantial across the continent.
The drought triggered widespread consequences including mandatory water restrictions in multiple countries, with southern England implementing hosepipe bans. Devastating wildfires spread through Spain and France, while agricultural sectors experienced severe losses. European grain production faced an estimated loss of 9 million tonnes, with France anticipating its worst maize harvest in 50 years and Romania losing over one million hectares of crops. Water levels in major rivers dropped significantly, reducing hydroelectric power generation and limiting commercial navigation on cargo routes. The Rhine at Lobith in the Netherlands fell below minimum levels recorded during the heat event of 1976.
Researchers warned that widespread disruptions to water availability and energy production could elevate food and energy costs, disproportionately affecting low-income populations. Scientists noted an emerging pattern of soil drying beginning in spring, before summer onset, driven by increased atmospheric moisture demand as temperatures rise. The 2026 drought arrived approximately two months earlier than a drought event that occurred in 2022. Researchers projected that if global emissions continue on current trajectories, reaching the predicted warming levels could double the frequency of intense evaporative summer conditions across Europe, necessitating rapid and substantial reductions in greenhouse gas emissions.
