London / RankWire.AI / – A detailed scientific report confirms that human activities are the main cause of the extreme dry spells currently plaguing Europe, clearly illustrating how climate change is intensifying drought across the continent. An international research team concluded that soaring temperatures, rather than just reduced rainfall, are the primary factors behind the record drought conditions. After a historic heatwave in June, Europe is experiencing dried-up rivers, stringent water restrictions, and widespread wildfires. The recent study shows that the hotter climate accelerates the loss of moisture from soils, lakes, and rivers, greatly increasing the likelihood of conditions becoming completely arid. Although spring rainfall was below average, it is the climate-driven heat that has made the drought significantly worse.
The World Weather Attribution group released the study explaining how rising temperatures deplete natural water sources. Mariam Zachariah from Imperial College London pointed out that the drought is primarily caused by a warmer atmosphere leading to more moisture deficits on land, not just by decreased rainfall. This means the risk of drought continues to grow even when rainfall patterns stay relatively stable. Scientists explain that for each one-degree Celsius rise in temperature, the atmosphere can hold about seven percent more water vapor. This additional capacity leads to increased evaporation from soil and vegetation across the landscape.
Using extensive weather data and sophisticated computer models, researchers measured how the likelihood of these droughts has changed by comparing today’s hotter climate to a scenario 1.4 degrees Celsius cooler. Their results show that soils in western Europe are now five times more prone to extreme dryness than in a world without human-induced warming. In eastern Europe, such moisture deficits are 11 times more likely. The study also found that the exceptionally high evaporative demand observed from April to June made drought conditions about 80 times more probable. Consequently, rainfall deficits that once wouldn’t cause severe drought now produce much drier soils.
Dominik Schumacher of ETH Zurich highlighted the increased tendency for unexpected soil drying during spring, before summer begins. He explained that as temperatures rise, the atmosphere’s thirst intensifies, rapidly drawing moisture from rivers, lakes, reservoirs, and soils. The combination of a relatively wet start to the year followed by intense heat created ideal conditions for large wildfires. The rapid soil drying primed landscapes for ignition, resulting in severe fires across multiple countries. The analysis confirms that climate change is shifting European weather patterns into highly dangerous cycles, exacerbating droughts across the continent.
The agricultural sector is experiencing unprecedented stress due to widespread soil moisture loss. These droughts are causing severe hardships for farmers, leading to historic crop failures across borders. France, for example, is projected to have its lowest maize harvest in 50 years, indicating serious disruptions to food production. Meanwhile, Romania has lost over one million hectares of maize, threatening supply chain stability. These domestic shortages, coupled with ongoing global conflicts, risk driving up food prices and disproportionately impacting low-income households.
Water-related impacts are worsening economic losses, with unusually low river levels disrupting vital shipping routes. Major waterways are experiencing significant traffic interruptions, reflecting the deepening water scarcity crisis across Europe. Reduced flows threaten hydropower-dependent energy production in several regions. Data from the Copernicus Climate Change Service confirmed that June was the hottest on record in western Europe. Many countries have already implemented emergency restrictions or temporary bans on non-essential water use to conserve limited supplies.
Scientists warn that if global temperatures continue rising, drought conditions could become more frequent. Experts emphasize that these evaporative extremes are occurring at 1.4 degrees Celsius of warming, underscoring the immediate risks posed by current emission levels. Should global temperatures reach 2.8 degrees Celsius as projected, the likelihood of such drought-fueling conditions could double. Without urgent and aggressive efforts to reduce emissions, experts warn Europe faces a future of ever-increasing, severe, and persistent dry summers.
