The lowest temperature recorded in the northern hemisphere was born. Can it really survive at MINUS 70 degrees?

As a senior living in Harbin for 23 years (drifting north after graduation), I really feel that it is impossible to survive at MINUS 70 degrees. It is estimated that it is difficult to drive geothermal energy at home. After all, it's only MINUS 30 degrees, which has already burned the Northeast. I vaguely remember that when I was in college, 50% of the remaining power was frozen, making it difficult to turn on the IPhone. No wonder Apple's sales in Russia were not good a few years ago, but it was frozen (manual joke).

1. The lowest temperature recorded in the northern hemisphere is 69.6 degrees, which was recorded by an interesting website in the United States on September 24th. It happened in Greenland, Denmark 199 1, and the lowest temperature before was in a certain area of Russia. Anyway, you don't know, so I won't look it up on purpose. If you are interested, go out and turn left to Baidu. What does this temperature probably represent? Let me explain science briefly. At MINUS 30 degrees, people's hands will feel particularly cold when they are taken out for about 20 seconds without gloves, and they will basically freeze for three to five minutes.

It can appear at MINUS 40 degrees, and the spilled water will quickly appear physical phenomena caused by rapid cooling, giving people a visual effect of rapid freezing. More than 50 degrees below zero can basically satisfy many people's fantasies about the northeast, and spit and freeze into ice. Sorry, 60 degrees below zero. It is estimated that it is difficult for friends living in Mohe to answer this question. After all, they probably haven't experienced it.

2. Can you really survive at minus 70 degrees? In fact, even at MINUS 30 degrees, human beings can't survive in the outdoor environment for a long time. We live by heating and geothermal energy at home, and air conditioning cannot be specified. After all, when it blows your home warm, you will freeze to death. It's nearly MINUS 70 degrees. In my opinion, even if geothermal heat is on indoors, it may be difficult to offset the cold that seeps in from outside. Of course, if human science and technology want to survive, it is estimated that the problem of MINUS 170 degrees is not big. After all, there are human outposts in Antarctica, and I have never heard of freezing to death.
