The World Health Organization has warned that Europe could experience additional weeks of dangerous heat as another major weather system develops over the Atlantic. Extreme temperatures are particularly dangerous for older people, children, outdoor workers and people with existing medical conditions. Previous heatwaves have forced schools to close, increased pressure on hospitals and raised the risk of wildfires across several European countries. Health authorities are urging governments to improve warning systems, provide cooling centres and protect vulnerable communities. Scientists say climate change is increasing the frequency, duration and intensity of extreme heat events across the continent.
