London is on high alert as a severe air pollution warning is issued, coinciding with an extreme heat warning that's set to bring temperatures of up to 39°C to parts of the capital. The Met Office has sounded the alarm for a large swathe of England and Wales, where health officials are urging vulnerable individuals to take extra precautions.
The combination of hot air masses and stagnant conditions is creating an ideal breeding ground for pollutants like ozone, which can wreak havoc on respiratory systems. Public health experts warn those with pre-existing heart or lung conditions, the elderly, and young children to be particularly cautious, advising them to stay hydrated, avoid strenuous activity, and keep out of direct sunlight during peak hours.
Met Office warnings are currently in effect for 16 areas across England and Wales, covering major regions including London & South East England. While Scotland and Northern Ireland are expected to see rising temperatures, they remain under lower-level heat advisories. The UK-wide heat warning is expected to bring temperatures above 30°C nationwide, with isolated highs of up to 39°C possible in the south-east.
Experts say this dual threat highlights the growing risks posed by climate change. Local authorities are taking steps to mitigate the impact, setting up cooling centres and ramping up public health messaging. Residents are advised to stay tuned for updates from local news and official government sources as they navigate these challenging conditions.
In addition to the heat warning, the UK's four nations will also face increased air pollution levels, with forecasters predicting light winds that will allow pollutants to accumulate in urban areas. This dual threat poses a significant risk to public health, underscoring the need for vigilance and preparedness across the country.
