A heatwave has brought sweltering temperatures to London, with thermal camera images showing surface temperatures reaching over 50 degrees in some areas, including pavements, rail platforms, and playgrounds.
The extreme heat has raised concerns about the impact of climate change, with warnings that the UK could reach temperatures of 45C regularly in the future. Met Office scientists have stated that this is a plausible scenario, driven by human-induced climate change, which is making heatwaves more intense and likely.
A leading scientist has warned that the dangerous tipping point of 2C is no longer a distant threat, but a reality that could be reached sooner than predicted, bringing with it more deaths, floods, droughts, and food shortages. The recent heatwave has highlighted the need for cities to adapt to more frequent and intense heatwaves, with measures such as green space and canopy cover helping to mitigate the effects.
London has already taken steps to prepare for extreme heat, with the city's mayor unveiling a heat emergency plan inspired by the US city of Phoenix. The plan aims to help the city cope with the impacts of heatwaves, including heat stress and disruptions to transport, energy, and water supply.
Despite a temporary reprieve from the heat, with temperatures currently below 25C in London and the South East, another warm weather front is forecast to hit the UK over the weekend and into next week. The Met Office predicts a turn to warmer weather from Wednesday, with temperatures potentially reaching 30C in London and surrounding areas by Tuesday.
The ongoing heatwaves have also raised concerns about drought, with parts of the south remaining dry and at risk of another hosepipe ban. The majority of Kent is already under an official hosepipe ban, with fines of up to £1,000 for those who break it. Experts have warned that the heatwaves are not a one-off, but a sign of a broader trend of more frequent and intense heatwaves in the UK.
