How does the constant cold of Gethen contribute to the theme of isolation and loneliness?

The constant cold of Gethen contributes to the theme of isolation and loneliness because Genly does not fit in. The weather adds an additional degree of the coldness and overall detachment of Gethenians. In this world Genly is very lonely he has been away from his homeworld for most of his life as an envoy doing missions for the Ekumen and even though he looks no more than 30 he is, in reality, one-hundred twenty years old. He is very tall and his looks make him stand out way more. I think the author made the planet cold show how the people of gethen doesn't have any emotions. On Earth, there are four different seasons, all in which Genly has already experienced. However, Genly is a foreigner so he is not used to the weather being cold all the time. The cold weather builds onto the cold emotions of the Gethenians by adding the extra sense of solitude for Genly, making it twice as hard for him to achieve his mission due to the additional obstacle.  The constant cold of Gethen also contribute the mentality of Genly as well, throughout the book, we are given an explanation as to the normal weather patterns through the eyes of someone who is fairly used to temperature like those of Earth. Genly states that the temperature of Gethen seems to stay below even that of our subarctic regions.  Because of this, Genly must act and respond different due to the extreme temperatures of Gethen, which in turn sets him apart from the residents of Gethen.
