What would be the effect on earth seasons if the axis were tilted 28.5 degrees?
If the earth was tilted more than 22 degrees,the poles would recieve more direct sun in summer, and summers would be longer and warmer, and winters colder, longer, and darker.The polar ice caps would shrink and grow more with the seasons. The temperature at the equator would vary more.Spring and autumn would be shorter.This is an interesting question and a great thought exercise. Even at 28.5 degrees,the world’s climate would be profoundly different, and evolution would have taken a very different course, and we probably would not be here to ponder the question.
