# Seasonal variations would be impossible on a globe earth

Flat earthers argue that on a globe earth the days and nights would always be of equal length. This is insanity and a complete lack of understanding of the globe model. The globe model does a very good job of providing us with a logical explanation of the different lengths of the day and night and the changing of the seasons.

It may well be that the globe earthers model of the earth spinning like a top at various angles to produce the seasons is incorrect. But it is a logical description of a system that could produce different length days and the seasons we experience on earth. It does account for different lengths of day and night throughout the year and the changing of the seasons [through the change in the length of the day and by making the sun appear higher or lower in the sky]

This theory may be incorrect and it does seem unlikely that the earth would be a globe spinning on its axis tilted in this way as we do not see any of the other planets acting like this. But you have to admit it is an ingenious system and give credit to the creators of the globe earth model for dreaming it up.

Conclusion: This is not proof the earth is flat. It is an attempt to fault the globe earth model but it fails to do that also. It shows the writer does not understand the globe earth model.

• 59) Quoting Gabrielle Henriet, “The theory of the rotation of the earth may once and for all be definitely disposed of as impracticable by pointing out the following inadvertence. It is said that the rotation takes twenty-four hours and that its speed is uniform, in which case, necessarily, days and nights should have an identical duration of twelve hours each all the year round. The sun should invariably rise in the morning and set in the evening at the same hours, with the result that it would be the equinox every day from the 1st of January to the 31st of December. One should stop and reflect on this before saying that the earth has a movement of rotation. How does the system of gravitation account for the seasonal variations in the lengths of days and nights if the earth rotates at a uniform speed in twenty-four hours!?”
• 126) The Sun’s annual journey from tropic to tropic, solstice to solstice, is what determines the length and character of days, nights and seasons. This is why equatorial regions experience almost year-round summer and heat while higher latitudes North and especially South experience more distinct seasons with harsh winters. The heliocentric model claims seasons change based on the ball-Earth’s alleged “axial tilt” and “elliptical orbit” around the Sun, yet their flawed current model places us closest to the Sun (91,400,000 miles) in January when its actually winter, and farthest from the Sun (94,500,000 miles) in July when its actually summer throughout most of the Earth.

” This theory may be incorrect and it does seem unlikely that the earth would be a globe spinning on its axis tilted in this way as we do not see any of the other planets acting like this. ”

On the contrary:
Mars is tilted in almost the same way as Earth, with an inclination of about 25°. That is why we see seasons on Mars as well. Saturn and Neptune are tilted a bit more, 27° and 28°. Uranus with an axial tilt of 97° rotates on its side and Venus with 177° more or less rotates “upside down” or backwards; Jupiter has a small axial tilt of 3.3° and Mercury has virtually none (0.1°).

“That is why we see seasons on Mars as well.”

When did you see the seasons change on Mars? Do Martians take up skying in Winter? Do Venusians visit Mars in the Summer Months? If so, how do they like the drop in presumed air pressure?

So many questions, you should write a travelogue and climate report.

Why do you need that much derision? I will answer your 1st question, the rest is just mockery.

When you look through a telescope (not necessarily a professional one — a more expensive amateur telescope will do: http://spider.seds.org/spider/Mars/mars_a.html) you can see Mars rotate (take a series of pictures a few hours apart and you clearly see some surface features move from left to right), and so you can see that the axis of rotation is tilted with respect to its celestial path, and you can see polar caps on Mars, they come and go corresponding with wether the poles are tilted from or towards the Sun, which takes a period of about two years. That is what we mean by seasons on Mars.

I may be misinterpreting what you are trying to say, but it seems as if you mean that the seasons arise from a change in axial tilt. If so, I want to correct that. The axis always points in the same direction, like the illustration on top shows, at least on a relatively short time scale of centuries or so. Only on timescales of tens of thousands of years changes occur like precession and changes in inclination.

126) is showing that whoever wrote this, does not understand what the explanation for the seasons is. The fact that the Earth’s orbit is slightly elliptical, does not play a role in it at all. It is just the tilt with the axis always pointing to the celestial poles, which makes a hemisphere sometimes tilted towards the Sun and 6 months later away from the Sun. It also has nothing to do with how close the Sun is. Temperatures rise in spring and summer, because the net solar irradiation per m2 increases and the daylength increases.
The ellipticity does show itself in the size of the angular diameter of the Sun, which is 3% larger in january than in july.

If Earth’s solar radiation quantum depends on Earth’s supposed ball shape and tilt why is the Southern extremity much colder than the North? Do the North pole and Southern extremities have a different shape?

Antartctica is a land mass surrounded by ocean with strong westerly currents, that tend to isolate it from heat influx from lower latitudes. The arctic is an ocean surrounded by land masses. The northern ice cap is at most only a few meters thick and is mostly vanished at the end of each summer. The southern ice cap is up to a few kilometers thick and forms a strong temperature buffer. The northern hemisphere has far more land surface than the southern hemisphere, which has mostly water surface. Water has a much higher heat capacity than land. Just a few asymmetries between north and south that can explain different responses to the seasonal solar input. Apart from that, summers in the south (Australia, South Africa, Patagonia) can be as hot as in the north.
