Once the world was determined to be a sphere, and orbiting the sun, a reasonable explaination for warm and cold climates could be formulated. How did people explain the difference in climate between say England and Italy when the world was flat?
If you had enough wealth to be able to travel more than a few miles, chances are you had enough education to know that the Earth was a sphere.
Even if you didn’t believe in heliocentricity, seasons could be explained by observing that the sun follows regular patterns of fluctuating orbit – low in the sky during winter and high up during summer. I’m sure some ancient dude meticulously worked out the geocentric geometry to explain it all, but I don’t know who.
That’s easy – the Sun goes through the southern part of the sky, so it’s closer to places in the south, such as Italy. Once you get to Africa, the Sun is so close that it burns people’s skins, turning them black. Pretty obvious, oce you think about it.
Gods send whatever weather they want.
What? The weather is that much different somewhere else? Never heard of such nonsense…
The idea that things in the world have understandable explanations is a relatively new one. It was one of the big changes that came out of the age of enlightenment a few hundred years ago. People didn’t explain climate. It just was.
Doesn’t Sirius figure into this somehow?
You jest (I think) but I had a roomate who didn’t understand why Los Angeles needed to be in a different time zone than New York.
Cro-Magnon kid: Dad, why is it raining ?
Dad: Don’t ask silly questions
Maybe its the reverse…all those white folks in the northern climes reflect all that heat away, cooling the place down…meanwhile all those “dark” folks near the equator are absorbing all the heat and warming up their areas…
Makes perfect sense to me!
Ahhh…the solution to global warming…breed/clone a gazillion albino zombies…just selective breed the meaness out em!
Blll
Nobody in Italy knew of the existence of England until Rome conquered Gaul and began poking around its seacoast in the first century BC. (Likewise, nobody in England knew of the existence of Italy until that time.) By then, the ancient Greeks had worked out the sphericity of the Earth.
Before the Greeks, there were empires spanning hundreds of miles (the Persian and Egyptian, for example), but they had primarily an east-west orientation. Sphericity wouldn’t have helped much in explaining climate variations within those empires even if the inhabitants had known about it. There was more significant variation due to elevation and rainfall, having little correlation with latitude.
One which hasn’t entirely caught on everywhere, even our public schools.
Educated people have known the earth was round since the 4th century BC.
They don’t need to be. We could easily all go by the same time, but people like the sun to be generally above them at noon.
It’s somewhat of a related question, and I don’t feel like starting another thread:
When is the first recorded mention of understanding that sunrise is not simultaneous worldwide? It’s an assumption that is easily made and it’s not really a practical consideration unless you have high speed communication or transport.
You make an interesting point, since we don’t adjust the calendar for the Southern Hemisphere, yet people in Australia seem to be doing fine having Christmas at the height of summer.
I don’t have an answer to your question, but unless you have accurate, portable clocks or simultaneous communication, it’s not an easy assumption to make for a flat earther. Would be for a round earther, tho.
But strangely our Christmas cards still feature snow, sleighs, holly, etc… the world is odd. 
Don’t forget the yule log that starts the rangeland fires during the summer dry season.
This is the Dope. You can’t be Sirius, can you?
Not quite true:
And hundreds of years before that the phoenicians were sailing to Britain for tin.
