What is the coldest national capital in the world?
Ulaanbaatar. Owing to its high elevation (about 1,350 metres above sea level), relatively high latitude, location hundreds of kilometres from any coast, and the effects of the Siberian anticyclone, Ulaanbaatar is the coldest national capital in the world. It has an average annual temperature of −0.4 °C, as cold as Nuuk, Greenland, but Greenland is not independent.
