London / Euro Wire/ – According to a major scientific review, human activity is identified as the primary cause of the extreme dryness affecting Europe, with climate change significantly intensifying drought conditions across europe. An international group of climate scientists discovered that record-breaking heat levels are the main factor behind these conditions, surpassing the influence of seasonal rainfall deficits. European countries are experiencing collapsing river levels, widespread water use restrictions, and devastating wildfires following a historic June heatwave. Data shows that an increase in global temperatures accelerates moisture evaporation from land and water bodies, creating an environment that is increasingly dry and unstable. Despite below-average spring rainfall, it was the temperature spikes driven by climate change that worsened the drought to critical levels.
The study published by the World Weather Attribution group explains how rising temperatures actively deplete natural water reserves. Mariam Zachariah of Imperial College London emphasized that the drought is not mainly due to reduced rainfall but instead results from a warmer atmosphere that causes greater moisture deficits on land. This means that the risk of drought continues to grow even where rainfall patterns are stable. Scientists highlight that an atmosphere warmed by one degree Celsius can hold about seven percent more water vapor, leading directly to increased evaporation from soils and vegetation across the landscape.
Using comprehensive weather data and sophisticated computer models, researchers quantified how the likelihood of these extreme weather events has changed by comparing the current hotter climate with a world 1.4 degrees Celsius cooler. Results revealed that soils in western Europe are now five times more prone to extreme dryness than in a pre-warming scenario, while in eastern Europe, these soil moisture deficits are 11 times more probable. The analysis further indicated that the high evaporative demand observed from April to June in western Europe was about 80 times more likely. As a result, rainfall shortages that previously would not have caused severe drought now result in much drier soils.
Calls for Immediate Global Emissions Reductions
Dominik Schumacher from ETH Zurich pointed out that early signs of soil drying are evident even during spring, prior to the arrival of summer. He explained that as temperatures increase, the atmosphere’s thirst intensifies, rapidly drawing moisture from rivers, lakes, reservoirs, and soil. The combination of a relatively wet start to the year with extreme heat created ideal conditions for large wildfires. The rapid soil drying primed the land for ignition, contributing to severe fires across multiple nations. The findings confirm that climate change-driven droughts are shifting traditional weather patterns into highly dangerous cycles across europe.
The agricultural sector is under unprecedented pressure as vital soil moisture diminishes. Widespread drought is severely impacting farming communities, causing historic crop failures across various borders. France, for example, is projected to have its lowest maize harvest in 50 years, indicating a significant disruption in regional food supply. Meanwhile, Romania has lost more than one million hectares of maize, further threatening the stability of the agricultural supply chain. These domestic shortages, combined with ongoing global conflicts, could lead to higher food prices and disproportionately burden low-income households.
Projected Trends of Continued Warming and Its Consequences
Hydrological consequences are worsening the economic damage, as unusually low river levels disrupt vital cargo routes. Major shipping disruptions on key waterways reflect the escalating severity of the water scarcity crisis across the continent. Diminished river flows threaten energy production, especially in regions heavily reliant on hydropower. Data from the Copernicus Climate Change Service confirms that recent June was the hottest on record for western Europe. Many nations are already enforcing emergency restrictions or temporary bans on non-essential water use to conserve dwindling supplies.
Scientists warn that if global temperatures continue to rise, drought conditions may become even more common. They stress that these intense evaporative conditions are already occurring at 1.4 degrees Celsius of warming, underscoring the urgent need to reduce emissions. Should global temperatures reach 2.8 degrees Celsius as projected, the likelihood of such conditions could double. Without swift and substantial reductions in emissions, experts caution that Europe faces a future marked by persistently scorching and arid summers.
