Ultimately, this scenario will depend on whether or not this alternate Earth would orbit one G-type star or two, and whether dawn would still be in the east, like back home, or in the west, like in Venus. But for now, let's assume that this alternate Earth orbits one G-type star at a distance of 93 million miles. The one difference is this--the axial tilt varies between 19.7 and 26.9 degrees over a cycle of 122,000 years. Here is the map:
It's not much, so here is how it looks in comparison to our map, out of respect for how climate changes with latitude:
It still does not say much, I know, so I have sealed the deal with a mountain ranges map:
The ranges vary in height above sea level from 5,885 to 8,848 meters. The arrows indicate the directions in which the mountains are rising, therefore the landmasses are colliding with each other. It's reasonable to believe that behind each plateau comparable to Tibet.
In the event that one of you would be asking about atmosphere, since it does play a part in climate, too, oxygen makes up one-third of the atmosphere and there are 4500 parts per million of carbon dioxide.
So with all the information listed above, what would the climate of this alternate Earth be like?
(I'm not looking for all the Koppen complexities, just something more basic.)
