Europe this year is not only hot, but hot in a way that feeds itself. The mechanism behind the fifth heat wave that CBS News has documented is not a single weather event, but a feedback loop: dry soil loses its natural cooling ability, making heat easier to accumulate, and heat dries the soil further. Samantha Burgess, head of climate strategy at the European Centre for Medium-Range Weather Forecasts, describes this as a clear example of how heat and drought are reinforcing each other.
This is a clear example of how heat and drought are reinforcing each other, according to European climate experts.
The numbers behind record heat
Average temperatures in June and July across Western Europe reached unprecedented levels, surpassing records from 2022. At ground level, soil moisture in Western Europe in July 2026 is significantly lower than in July 2022 — that is, lower even than the most severe drought this continent has experienced in recent times. The flow of vital rivers such as the Seine, Rhine, and Danube are all unusually weak, directly affecting transportation, irrigation, and energy production in many countries.
Drought is not evenly distributed. According to data from Eurostat and the European Environment Agency, Cyprus uses up to 72% of its freshwater resources annually, sometimes reaching 92% in summer — while a country using just 20% of its water resources enters warning territory. Malta, Greece, Romania, Portugal, Italy, and Spain are all in this warning zone during summer. A report from the European Environment Agency titled 'Overheated and Underprepared' estimates that roughly one in ten EU citizens faces difficulty accessing clean, safe water.
Visible consequences: wildfires and deaths
Drought and heat are more than just statistics. In France, public health authorities recorded an additional 5,700 deaths beyond normal levels in June alone, and a historic forest fire in the country's southwest forced 220,000 people to evacuate — one of the largest mass evacuations on the continent since World War II. Meanwhile, wildfires spread through the Hautes Fagnes nature park in eastern Belgium, hundreds of people fled a seaside resort in northern Greece, and a village in southwestern France emptied, while two people died in wildfires on a Greek island and another person died in Croatia.
Why this year, and what comes next
Behind the numbers lie two resonating forces. Copernicus Director Carlo Buontempo argues that greenhouse gases remain the primary driver of warming trends, but an El Niño forming is seen as the direct cause pushing sea surface temperatures to new record levels in July. This is not Europe's problem alone: scientists predict the world could set a new global temperature record by late 2026 or early 2027.
What worries European policymakers is that the European Environment Agency forecasts water scarcity will increase in frequency and severity at least until 2030 — meaning this summer is not an unusual event that will pass, but a pattern of what is to come. For countries heavily dependent on summer tourism and irrigated agriculture like Spain, Greece, or Cyprus, water management will no longer be a seasonal technical issue, but a long-term structural pressure on both economy and infrastructure.
