Welcome to the Russian village of Oymyakon, one of the coldest permanently inhabited regions on earth. Yesterday, the temperature dropped to a frostbitingly cold −55 °C, or −67 °F, but that didn't stop students from going to school. Just to give a sense of how cold it gets, Oymyakon's permafrost remains frozen year-round and it's responsible for coldest officially recorded temperature in the northern hemisphere, recording −67.7 °C (−89.9 °F) on February 6, 1933.
