I must point that this -71 C is the record low, that happened once in a whole century of observations, and no living human in Yakutia sees this in their entire lifetime. In my homecity, Novosibirsk in South Siberia, the record low is around -50 or a bit lower, and it hasn't happened in my lifetime. So Youtubers writing these titles "Yakutia -70 C" are just trying to impress you with numbers, as if -30s, that people endure there daily for 3 months, were a joke and beach season. In my home city in south-west Siberia temperature thresholds are these: normal tempratures in winter 0..-25 C, from -25 to -30 C schools shut down depending on wind speed. -30 C and below is extreme that lasts just several days in a year. -40 C happens not every year and only at night, and I only saw -45..47 C once in my whole lifetime -- in 2001, when such extreme cold lasted a week. And no, life there (South Siberia) isn't a toil, houses are heated well, outdoors positive temperatures come in March, and in June-August day temperatures are above +20 C. I guess the respective temperatures for Yakutia would be -45 to start shutting down schools, -50 is very cold and people prefer staying home, and -60 is a very rare occasion, not happening every year.
