4, Summer Would be cooler.


Because seasons are caused by the changing angles that sunlight strikes the Earth (due to it's tilted axis), a decrease in tilt would mean less extreme seasons. Spring and fall are not affected by tilt because they are at the point in orbit where sunlight is hitting the earth evenly. However, less tilt would mean less of a change in angle around the orbit and therefore cooler summers and warmer winters.
