A severe heatwave has broken temperature records across Germany, Denmark and the Czech Republic, with thermometers reaching unprecedented highs. In Germany, the city of Berlin recorded 39.2°C on Monday, surpassing the previous national record set in 2015. Denmark saw its highest temperature in over a decade, with Copenhagen hitting 36.4°C. The Czech Republic reported similar extremes, with Prague reaching 38.1°C.
The UK Met Office has been commended for its early warning systems, which accurately forecast the heatwave's trajectory and intensity. This allowed national authorities in the affected countries to issue health advisories and activate emergency cooling centres. The Met Office's collaboration with European meteorological agencies has been highlighted as a model for cross-border disaster preparedness.
The heatwave is attributed to a stationary high-pressure system over Scandinavia, drawing hot air from the Sahara. Climate scientists warn that such events are becoming more frequent due to global warming. The German Weather Service (DWD) noted that the likelihood of a heatwave of this magnitude has increased fivefold since pre-industrial times.
Public health officials have reported a spike in heat-related illnesses, with several fatalities suspected. In Germany, hospitals in Berlin and Hamburg have reported increased admissions for dehydration and heatstroke. Denmark and the Czech Republic have activated national heat-health action plans, urging vulnerable populations to stay indoors.
The UK Met Office's early warning system, known as the Heat Health Alert, was triggered four days before the peak temperatures. This enabled the UK's National Health Service to prepare for increased demand. The system uses a combination of meteorological data and public health modelling to issue graded warnings.
The European Centre for Medium-Range Weather Forecasts (ECMWF) has praised the coordination between national agencies. A spokesperson said that sharing real-time data was essential for timely alerts. The heatwave is expected to subside by the end of the week, but residual risks remain.
Political leaders have used the event to push for stronger climate resilience measures. German Chancellor Angela Merkel called for investment in green infrastructure, while Danish Prime Minister Mette Frederiksen stressed the need for international cooperation. The Czech government has announced funding for urban cooling projects.
The heatwave has also caused transport disruptions, with rail services in Germany and the Czech Republic reducing speeds to prevent track buckling. Power grids have come under strain due to increased air conditioning use. Despite the challenges, the early warnings have been credited with preventing worse outcomes.
The UK Met Office's reputation has been enhanced, with experts noting that its model was crucial in predicting the heatwave's path. The agency's chief scientist said that continued investment in climate modelling was essential. The event underscores the growing importance of accurate weather prediction in a changing climate.
