The Earth's axial tilt is what gives us our seasons.
Without that axial tilt of 23.5 degrees, we wouldn't have any seasons.

We would have no seasons and the surface temperature at any point on the earth would be the same during both July and January. The equatorial region of our planet would be intolerably hot all year and the poles would remain fairly cold. Ice would accumulate at the poles. The weather patterns would be stationary with permanently positioned warm and cold air masses. Some areas would continually be very humid while other areas would be quite arid. Only the mid-latitudes would be comfortable for human habitation and suitable for cultivation. Only about one half of our presently farmable lands could grow crops.

Note to Pluto035: Joseph is correct in his statement that the equator would be hotter. Without an axial tilt, the suns rays would constantly enter the atmosphere at a direct angle at the equator, something they presently do not because of the 23.5 degree tilt. Since it is the angle of the suns rays which affect temperature, a perpendicular axis would have a substantial affect on the temperatures at the equator.

Ok so under this idea - the earth is straight up and down, no tilt. So day and night would be the same for everyone. the earth surface would receive the same amount of sunlight all year round, the sun would appear the same distance above the horizon year round. True, we are tilted 23 1/2 degrees but with out that tilt, the equator would receive more direct sunlight "all year". About the same it gets at noon time during the equinoxes. (the time and position where the sun is directly over the equator)

If the earth's axis has no tilt then,
(1) The sun will be shining over the equator throughout the year and places over the equator will be getting maximum solar radiation and the poles minimum solar radiation throughout the year.
(2)Day time and night time wil be equal in all places for the whole year.
(3) There will be no seasons as all places will be equally exposed to the sun even though the intensity of radiation may vary from equator to poles due to the inclination of the sun's rays.
But when the earth is in the perigee(nearest position to sun) position along its elliptical orbit around the sun,the temperatures will be more and it may be comparatively less when the earth is in the apogee position(farthest position).This may sometimes look like summer and winter.If it is so, all places will experience summer and winter simultaneously.

A few days ago in the N. Hemisphere came the same event that will happen again in the S. Hemisphere in June. So tell me how observers handle both? If just one, then why for an event affecting only part of the world while the others are in limbo? What in a person would yearn to celebrate the longest night, except that person be a creature of the darkness? Note Christmas is celebrated upon the dawn of lighting of the darkness, (celebrating the act of Jesus bringing light into the world by His birth) observed about 3 days later than Winter Solstice, yet is celebrated world wide once a year.

They're wouldn't be any seasons, but the temperature wouldn't be the same everyone, we'd all just be stuck in one season because that is controlled by which way we are tilted towards the sun.
Joseph... why would the equator be any warmer? It's always the same angle towards the sun weather or not the earth is tilted.

With the tilt when the northern hemisphere is in summer the southern hemisphere is in winter. Without the tilt the northern and southern hemisphere would be in the same season. We would still have all four seasons because of our orbit.

This is just a guess, but I think that every country would have the same temperatures and amount of sunlight, because they were all facing the Sun at the same angle.

Seasons? I have no idea, although maybe there wouldn't be any.

It would be very bad,as the ice area would be much bigger so less room for croups to grow food. I doubt that it might only support 4 billion.

the poles wouldn't be able to sustain any life, du to always being dark, and not getting enough heat that's necesarry to support the life that's there now. and the equator would be a lot hotter. essentially, the ocean tempuratures would increase, and life wouldn't be able to be sustained.
