As the UK braces for soaring temperatures, authorities have issued a series of heat and pollution alerts across the country. London is under a high air pollution warning, with temperatures forecast to climb above 30°C. The alert, triggered by City Hall and based on predictions from Imperial College London, highlights the risk of increased ozone levels due to strong sunshine and airflow from mainland Europe. Deputy Mayor Mete Coban emphasized the link between London's "toxic air" and approximately 4,000 premature deaths annually, urging residents to minimize pollution by avoiding idling engines and burning waste.

Meanwhile, the UK Health Security Agency has issued amber heat health warnings for several regions, including London, the East Midlands, and the South East, as temperatures are expected to peak at 34°C. The agency warns of potential disruptions to travel and healthcare services, with vulnerable populations, such as the elderly and those with pre-existing conditions, at heightened risk.

Hospital emergency departments have reported a surge in visits due to heat-related illnesses. Dr. Sohail Abbas from the NHS West Yorkshire Integrated Care Board advises the public to stay hydrated, avoid the sun during peak hours, and check on vulnerable neighbors. Symptoms of heat exhaustion, such as dizziness and excessive sweating, should be addressed promptly to prevent escalation to heatstroke.

The national drought group has raised concerns over "nationally significant" water shortages affecting agriculture and wildlife. The ongoing heatwave, driven by high pressure from Europe, is exacerbating these conditions, with some areas experiencing their fourth heatwave of the summer.

Experts attribute the intensifying extreme weather to climate change, urging the public to take necessary precautions. Dr. Paul Coleman from the UKHSA stresses the importance of community awareness and support for vulnerable individuals during these challenging conditions.
