Earth's Axial Tilt

Earth is tipped on its axis relative to our orbit ar in the sun. Because of that tipping, for one part of the year, the northern hemisphere is tipped towards the sun and six months later, that same hemisphere is tipped away from the sun. The equator at does not go through seasons. So if you want to undo the tilt and have earth just pointing straight up and down, no seasons, but it would still rotated,. we would still rotate on our axis and still revolve around the sun. And for anyone, for again, unless it's this rainy season versus no ight we be no temperature, fased seasons of any significant measure, would we still have cold and warm
