We would probably still have seasons, though it may be hotter overall. What actually makes more of a difference is the CO2 content of our atmosphere. During the age of the dinosaurs our sun did not burn as brightly, or as hot, as it does now, but the average temperature of the Earth was higher. The evidence supports this idea because there are spores from tropical plants in the area that is now Greenland and Iceland. Since the CO2 level was higher, it trapped sunlight by the greenhouse effect and warmed the Earth to a higher temperature than the sun does today. Our CO2 level has been lowering until the industrial revolution and the population explosion we know of as today. The changing world climate is now evidence that the CO2 level is, once again, rising by the 'global warming' affect of industrial burning of fossil fuels. Only this time it is from an unnatural source, so we may nit have control over its impact on the environment.
In that case, there would be hardly any seasons. There would still be slight variations in yearly temperatures, as a result of the fact that Earth is sometimes closer to the Sun.
The Earth would not have seasons if its axis was not tilted with respect to its orbit around the Sun. Seasons are caused by this tilt, which affects the angle at which sunlight reaches different parts of the Earth throughout the year.
If Earth moved closer to the sun, temperatures would increase significantly, leading to the melting of ice caps, changes in weather patterns, and potential harm to ecosystems and biodiversity. Life as we know it would be threatened due to the extreme heat and its impacts on the environment.
The Earth becomes hotter To be more precise, our atmosphere would ignite, we would be exposed to super-heated solar winds and roast. Edit: Earth gets closer to the sun every year. That's why we have summer. It depends on how much closer it gets.
If the earth was not tilted there would be little to no change in temperature, resulting in no seasons.

The seasons are not caused by Earth's elliptical orbit but by the angled axis that the Earth rotates about. That being said, if Earth;s orbit were more elliptical by a significant amount, it would be logical to deduce that daytime temperatures (at least) would increase when the Earth is cloest to the Sun. -J The lengths of the seasons would be affected, since the earth (or any other body) travels faster as it gets closer to the sun. Currently, the earth is closest to the sun in early January and farthest in early July, which is why the northern hemisphere winter is about 89 days while the northern hemisphere summer is about 93½ days. -HW
There would be no seasons. Each place on Earth would have a constant climate. Temperature would change from night to day, but not as it changes between the seasons.
The closer we are to the Sun, the more light would hit the Earth. It would heat up the Earth a little. The time it takes to complete one orbit around the Sun is proportional to the radius of the orbit, so if we were closer to the Sun, the year would be shorter.
If the Earth were tilted at 40 degrees, the seasons would be more extreme in the regions closer to the poles. This would result in longer and colder winters, and hotter summers. The equatorial regions might experience less variation in temperature throughout the year.
If Earth's axis were perpendicular to its orbital plane (i.e., the axis of rotation were upright), there would be no change in the Earth's relationship with the Sun. However, this change would eliminate the seasons as we know them, leading to more consistent temperatures around the world. Climate patterns and biodiversity could also be greatly affected as a result.
no Next comment by Shamus: I haven't done any research into this but i would believe that summer in the northern hemisphere is caused by the northern part of the earth tilting towards the sun so that it is closer to it than the southern hemisphere and vice versa. Because the northern part of Earth tilts closer to the sun the southern hemisphere would be slightly further away causing colder seasons.
The seasons on Earth are primarily caused by the tilt of the Earth's axis. As the Earth orbits the Sun, different parts of the planet receive varying amounts of sunlight, resulting in the changes in temperature and weather patterns that we experience as the seasons.
If the Earth's rotation axis had no inclination, there would be no variation in the angle at which sunlight hits different parts of the Earth's surface, resulting in no distinct seasons. Areas at the equator would experience consistent temperatures year-round, while areas closer to the poles would have milder but less distinct seasonal changes.
When there is slow rotation and orbit around the sun , day and night in earth is affected not only that but due to slow rotation seasons in earth also changes slowly .As there is sloe season change in directly affects on agriculture on earth.
There would be no seasons on Earth if the Earth's axis had no tilt because throughout the year the Earth would get an equal amount of sun everywhere.
