Unusually hot weather is almost unbearable to travel on the UK’s underground train network. Since pedestrians bake in 30C heat at the road level, the temperature inside some tube trains may be about 5C hot, demanding shade between the roadside trees.
This is a condition that can timber the economy of a city and endanger the health of the passengers, and it is becoming more unbearable with each passing summer due to climate change.
It is not easy to find data on how hot is under the ground. Transport to London, or TFL, measures the platform temperature “periodically”, but does not monitor them in real time or records heat levels in train vehicles.
Bloomberg News is creating a London tube heat index, collecting data on the central line at the same time every day using an anernet 4 sensor about the size of a drink coaster, which logs to temperature and humidity at a time interval.
The data recorded during a summer wave earlier this month was shown trains on the central line – the oldest and deepest in the network at 20 meters below the surface level – one of the oldest and deepest – one of the road levels was 3C over the road level during a movement from the bank station, in the city’s financial district, for the Bond Street Station, according to the Bond Street Station, according to the Bond Street Station. Even in more specific summer days, the temperature was at least 1.5C warm.
Keep another way, using the official definition of a summer wave for three consecutive days of London for three consecutive days of 28C maximum temperature, London travelers are constantly tolerating-to-wave situations.
In publicly available reports, TFL accepts excessive heat as a major and growing risk for health and safety of passengers, employees and physical networks. Britain was at least 1 C coolers when the land trains first went into service in 1863, and the temperature has gone to underground much faster than the surface.
London is not the only city in the world with infrastructure which is unsuitable for a warming climate. But the tube is particularly insecure, with deep, narrow tunnels that trap heat with rail-car brakes, friction and motors, and its full vehicles have limited ventilation.
Research published on 20 June by Imperial College London shows that Global Warming has today increased the possibility of a summer wave of initial season in UK once every 50 years in a pre-industrial climate every five years. This summer has already seen excessive heat this month, including a forecast on Monday and Tuesday. This week the maximum temperature can reach 34C, which has been three times in June since the 1960s, according to the UK Met Office.
The biggest performance so far in July 2022 was the biggest performance in the Tube’s heat deficiency, when the temperature in the UK first pushed 40C. According to TFL, train tracks, overhead cables and transport equipment failed.
For TFL, short -term heat wave planning includes announcements on placards and trains in stations, which encourage passengers to carry water with them. In the long term, the age of the network tunnels, its physical boundaries and the geographical location below the dense city roads, according to TFL spokesperson Sean Kolfer, severely limit the options to deal with excessive heat.
“There is not a large amount not more we can,” he said. “The temperature on the underground is not immediately variable.”
According to TFL, only 40% of vehicles on the metro network are air -conditioned. The city’s newest line, which came into operation in 2022 and is named after Queen Elizabeth, is the only service with cars that are completely cool.
Andrew Renninger, a researcher at University College London, said that London has long -begged and this heat is about underground heat, but this grief takes an average toll over the city’s economy and culture.
Working with Carmen Cabarera-Arano, a scientist at the University of Liverpool, he used the database of rent payment and anonymous mobile phone data to do research on how the temperature affects the travel pattern within cities. While the pair have not studied London, they found that people stayed at home and responded to the waves of summer in Spain and other European countries.
“Heat acts as a tax on activity, and different activities have different elasticity,” Rennninger said. The first trips to disappear are the most discretionary – holiday, entertainment and food – while the journey required for work and school is less than a hit, shows research.
TFL’s data returned it, with 5 million less passenger trips recorded during the three-day summer wave in 2022, resulting in a loss of £ 8 million ($ 11 million) in rent revenue.
This is not just a matter of turning to work with sweat, there can be serious health effects of heat, especially between people aged 65 years and above, according to the government.
A climatic scientist Fredarry, a climate scientist at Imperial College London, said that the risks have been designed to increase themselves that describe themselves underground. When the temperature rises to 35 C, even very healthy and fit people are accustomed to warm climate who suffer from adverse effects, they said. Bloomberg recorded temperatures in the form of 33C on mid and Victoria lines this month.
