I feel genuinely sorry for you folks who have to struggle to get to work in all weathers. I did the same for 35 years.
As a retired person I have the option of hibernation. Well semi- hibernation, but I found this

Human hibernation
A Practice closely akin to hibernation is said to be general among Russian peasants in the Pskov Government, where food is scanty to a degree almost equivalent to chronic famine. Not having provisions enough to carry them through the whole year, they adopt the economical expedient of spending one half of it in sleep. This custom has existed among them from time immemorial. At the first fall of snow the whole family gathers round the stove, lies down, ceases to wrestle with the problems of human existence, and quietly goes to sleep. Once a day every one wakes up to eat a piece of hard bread, of which an amount sufficient to last six months has providently been baked in the previous autumn. When the bread has been washed down with a draught of water, everyone goes to sleep again. The members of the family take it in turn to watch and keep the fire alight. After six months of this reposeful existence the family wakes up, shakes itself, goes out to see if the grass is growing, and by-and-by sets to work at summer tasks. The country remains comparatively lively till the following winter, when again all signs of life disappear and all is silent, except we presume for the snores of the sleepers. This winter sleep is called lotska. These simple folk evidently come within the terms of Touchstone's definition of a natural philosopher; and many whose lot is cast in places where men are breathless with the fierce race for power or glory or wealth would doubtless be disposed to say of them, 0 fortunatos nimium sua si bona norint! In addition to the economic advantages of hibernation, the mere thought of a sleep which knits up the ravelled sleeve of care for half a year on end is calculated to fill our harassed souls with envy. We, doomed to dwell here where men sit and hear each other groan, can scarce imagine what it must be for six whole months out of the twelve to be in the state of Nirvana longed for by Eastern sages, free from the stress of life, from the need to labour, from the multitudinous burdens, anxieties, and vexations of existence.
What an extreme way to survive in a harsh environment!! At least it demonstrates that survival is possible and gives hope that severe climate change will not neccessarily lead to our extinction.
