The Victoria line of the London Underground has experienced a dramatic increase in temperatures, with averages rising nearly 30% since 2013. This trend is starkly contrasted by a mere 7% increase in temperatures across all Underground lines over the same period. The rising heat poses operational challenges for Transport for London (TfL), which is struggling to manage these conditions effectively. Past conditions offered the Underground as a cool refuge, but climate control has deteriorated due to heating caused by trains and commuters. Potential solutions discussed include improving air circulation, installing air conditioning systems, and utilizing geological thermal energy storage to mitigate the heat problem. Suggestions include rehydrating the surrounding clay to maintain cooler temperatures, and using heat generated in the tunnels for warming domestic water systems above ground. However, challenges persist in finding space for necessary infrastructure, and the situation is elaborated to suggest that systemic change may take time, reflecting the long-term nature of the problem.
