Europe bakes as a record-shattering heat wave grips the continent

A ferocious heat wave shattered temperature records across Europe this July, as a plume of hot air drawn up from the Sahara pushed the mercury to all-time highs in several countries and tested the resilience of a continent largely unaccustomed to such extremes.

National heat records were broken in multiple nations, with readings climbing well above 40 degrees Celsius in places that rarely see such temperatures. Cities better designed for cool, damp weather than for intense heat struggled, with relatively few homes and buildings equipped with air conditioning.

The heat strained power grids, buckled roads and railways, and posed serious health risks, particularly for the elderly and the vulnerable. Authorities issued warnings and opened cooling spaces, mindful of past heat waves that had caused large numbers of deaths.

Scientists were quick to link the severity of the event to climate change, noting that heat waves are becoming more frequent, more intense and longer-lasting as the planet warms. Studies increasingly show that human-caused warming makes such extreme heat far more likely.

The episode was part of a broader pattern, with the month going on to be measured as one of the hottest ever recorded globally. For Europe, the heat wave was a stark preview of a warming future, and a prompt to rethink how its cities, infrastructure and health systems cope with temperatures once considered unthinkable.
