Imagine endless wavering grass with light breezes and lazy rivers, like a forever summer day. But, if you leave this idyllic zone, you will encounter bands of intense tropical heat or deserts. Head up or down to the poles, and an endless winter awaits.
I recently did a list swap with a fellow YA sci-fi author, Jennifer Lewy. Next to her pitch for my book, she posted a picture of herself in the snow. The contrast couldn’t be starker to where I’m currently vacationing in the southern hemisphere on the beach in the heat.
This had me thinking about what makes the seasons exist — the tilt of the Earth. If this tilt didn’t exist, the outcome would be fascinating:
Quick caveat, there are completely competing articles out there on this thought experiment. It would be great for someone to actually computer model this (not saying this would be definitive either).
I’m going with below:
Constant Mild Temperatures: The temperate regions would experience a perpetual climate of comfortable warmth during the day and coolness at night, eliminating the need for seasonal clothing changes.
Absence of Seasonal Extremes: Extreme weather fluctuations between summer and winter would disappear, ensuring a consistent, predictable weather pattern.
Evenly Distributed Precipitation: Rainfall or snowfall would occur throughout the year, sustaining lush landscapes and picturesque snowscapes continually.
Perpetual Natural Beauty: Nature’s displays, such as foliage and flowers, would remain vibrant year-round, creating timeless scenic vistas.
Year-Round Agriculture: Farmers could cultivate crops continuously, leading to higher yields and a more reliable food supply.
Uninterrupted Outdoor Activities: Outdoor enthusiasts could enjoy skiing, surfing, hiking, and other activities without seasonal restrictions, transforming popular destinations into year-round havens.
In this world, the temperate zones would offer a serene and dependable environment for human habitation, characterized by constant mildness, predictable weather, and uninterrupted enjoyment of nature and outdoor pursuits.
There would be smaller ice caps at the poles, because with the Earth’s axis no longer tilted, the polar regions would experience a constant low-angle sun throughout the year. There would be sea level implications, with the melting of polar ice caps at a slower pace than in a warming world with seasons.
It would definitely be a less dynamic world, but fascinating in other ways. In the Zantium universe, the world with no tilt had been colonized by humanoid warthogs and elephants, so all the lack of civilization development due to static lifestyles discussed online would not be a large factor.
