European summers are getting increasingly hotter alongside rising temperatures throughout the globe, but the growth of air-conditioning throughout the continent is still lagging behind that of the US and Australia.
Commuters on a Vienna U6 subway line felt the heat when carriages reached 35 degrees celsius this summer, higher than the restricted temperatures placed on livestock transport in the country.
European cities are finding themselves increasingly forced to upgrade their cooling systems on public transport, however this time around, instead of using AC on the overheated subway carriages, the publicly owned transport company decided to hand out 14,000 deodorant sticks instead.
