World's Coldest Cities: Surviving -55°C & Beyond

• Oymyakon, Russia, is the coldest inhabited place, with record lows of -67.7°C and average winter temperatures of -45°C to -50°C.
• Utqiagvik, Alaska, the northernmost US city, houses 4,500 Inupiat people who build homes on stilts to prevent permafrost melt.
• Yellowknife, Canada, a growing city of 20,000, experiences temperatures as low as -26°C and is known for diamond mining and Northern Lights viewing.
• Astana, Kazakhstan, can drop to -51.5°C due to its inland location on the Kazakh Steppe, allowing unhindered Arctic winds.
• Longyearbyen, Norway, the world's northernmost city, requires residents to carry rifles for polar bear protection and prohibits burials due to permafrost.
