It's -50C in Yakutsk, Russia, the coldest place on Earth - PHOTO

The swing in temperature between seasons is extreme, as it is not unusual for summer days to bask in 25C of glorious sunshine, only for the winter months to plunge 60 degrees - or more.The record low for Yakutsk was an unbearable February day when the mercury hit -64.4C, however today, the city experienced a 'mere' -49C.The ground underneath it is permanently frozen, making tall buildings difficult, and any major building project risky, as nearly everything has to be built on concrete piles above ground.Despite the deterring conditions - forget snow days, schools only close if the temperature drops below -52C - it is home to 270,000 people, a quarter of the entire population of Siberia.(dailymail.co.uk)ANN.Az
