Actually, the axial tilt is currently 23.44 deg and decreasing. The axial tilt is in a continuous cycle between 22.1 and 24.5 deg on a 41,000 year cycle, one of the Milankovich cycles known as obliquity.
Well, the seasons would be different. As the tilt of the axis decreases, the changes in seasons would be less and less noticeable until there would be no change at all at a tilt of zero degrees. Animals and plants who depend on different climates and/or seasons for mating/hibernating reasons might also be doomed...
A more interesting question would be what would the climate be like when the tilt is at any given angle.
Zero degrees - no change
5 degrees - small change, midnight sun only very close to the poles
10 degrees up to about 25 degrees - similar to what we have today
25 to 35 degrees - Interesting. Let's see - more extreme summers and winters.
Longer summer days, shorter winter days in the higher latitudes. The Arctic and Antarctic circle would be as far as 55 degrees north/south, which would put half of Scotland, to say nothing of Scandinavia, a great deal of Russia, the Baltic Republics, Canada, and all of Alaska except the southern tip, in darkness in late December and 24-hr light in June. The opposite can be said about the southern tip of South America. New Zealand would have an extremely short day (how short?) in June, and likely have frigid weather in June, similar to today's Finland in December.
The Tropic of Cancer/Capricorn would be at 35 north/south, which would give places like Syndey, Aukland, Buenos Aires, Cape Town as well as Tokyo, Oklahoma City, Los Angeles, a sweltering summertime climate simliar to Havana, Cuba, Florida today. We could go on and on.
35 to 45 degrees - This is even more interesting. Imagine the poles being temperate and the equator being frigid. Do a calculation of the average annual solar energy that impinges upon a given surface at a given latitude assuming a tilt of 45 degrees. Then do the same calculation for each season of the year.
45 to 90 degrees - More interesting even yet. Imagine the sun never setting at the north pole, being directly above.
First, it would take a titanic catastrophe to move the Earth's axial tilt; abruptly changing the Earth's "tilt" would CAUSE a catastrophe. It's not going to happen.
Second, Earth's axial tilt IS changing - VERY slowly.
Third, the overall effect of the change would depend on how much, and how fast. If the change is small and slow (as it is), it will probably have only very small effects. If the change was fairly rapid, then it might cause problems with plant and animal species that are accustomed to how things are now, and would increase the seasonal changes that we have every year.
If the earth were tipped at 35 degrees instead of 23.5 degrees, winters would be colder and summers would be hotter. During the summer, all glaciers and ice caps would melt. All snow would fall shortly after equinox and winters would be too dry for snow.
Probably about the same, as the amount of sunlight hitting the Earth would not change much, and the heat generated at the Earth's core wouldn't change at all.
However, a greater axial tilt would have the effect of emphasizing the effects of seasons; summers would likely be a little warmer and winters a little colder.
I am not a terrestrial Physicist but I can tell you the the seasons on this planet are caused by the Tilt of the earth. and a 11.5 Degree shift would be a dramatic shift, however I trust it would have the same effect, seasons would be created, though I think they would be far more dramatic than they are presently, more than likely it would be like Summer in Cairo , to Winter in Vostok.
The seasons would be more extreme: winter would be colder and summer would be hotter.
The polar ice caps might collaps. Hailey comet collision. and we may spin out of orbit and crash into something...
Depends on what angle it'd be at.
Less tilt = less seasonal changes.
More tilt = bigger seasonal changes.
The arctic circle would be nearer the equator. Summers and winters would be longer and more severe.
If the Earth's tilt wasn't at 23.5 degrees there would be an extreme difference in weather. Consider ourselves lucky.
Yes. A tilt of zero degrees would have no seasons.
Earth's axis has a tilt of 23.5 degrees; this is what causes seasons. 0 degrees: practically no seasons (there would be minor changes due to a varying distance from the Sun). 45 degrees: seasons would be much more pronounced.
None.Jupiter does not have seasons as easons are caused by a tilted axis, and Jupiter's axis is only tilted 3 degrees (not enough to cause seasons).
There are still 4, its just not a big difference between the seasons. . a08Deevic88 Join Me At www.ETangerineE.webs.com
The average temperature in Italy in Spring and Fall is 60 degrees Fahrenheit, in Winter, 45 degrees Fahrenheit, and in Summer, 75 degrees Fahrenheit.
Yes. A tilt of zero degrees would have no seasons.
Callisto does not have seasons due to is inclination of only 0.281 degrees

Jupiter doesn't have any seasons. This is because it only has a tilt of 3.13 degrees which is not enough for seasons.
The seasons are caused by this.The seasons are caused by this.The seasons are caused by this.The seasons are caused by this.
No, seasons are produced by axial tilt. Europa has an axial tilt of only 0.1 degrees, which is not enough for seasons.
22 seasons and the current longest streak.
Rachel Lillis for seasons 1 to 8, and Michele Knotz for seasons 9 to the current seasons.
It causes seasons on the earth
None.Jupiter does not have seasons as easons are caused by a tilted axis, and Jupiter's axis is only tilted 3 degrees (not enough to cause seasons).
That is the cause of the seasons.
The differences of the seasons would scarcely be detectable.
