When mining forced the Swedish town of Kiruna to move in 2014, city planners promised a fresh start. But residents say the new town has lost the warmth that defined the old one - both in spirit and temperature.
A study from the University of Gothenburg found that the new Kiruna, relocated to make way for an iron-ore mine, can be up to 10°C colder in winter than its predecessor. That’s because the city was rebuilt in a depression where cold air gathers, while tall buildings block the low Arctic sun for much of the year.
