What is the effect the perihelion and aphelion have on earths seasons?

The aphelion has many interesting effects on the earth. For one, the orbital velocity of the Earth slows down as it reaches its aphelion. It also has an effect on the climate. Due to the point in its orbit the Earth climate is made cooler and warmer in the Northern and Summer Hemisphere creating milder or more severe seasons. Some scientist hypothesize that major climate shifts like the Ice Ages are caused in part by major shifts in the Earth's Orbit which can alter its apsis points.
At aphelion, Earth receives 6.9% less of the solar radiation than at perihelion. Aphelion happens around July 4, so this means slightly cooler summers for the Northern Hemisphere and slightly cooler winter for the Southern Hemisphere..
Perihelion is the closest point to the sun in a planet's orbit. Perihelion is one of the two points of apsis on elliptical orbit. The closest point is generally called an periapsis and the farthest point apoapsis. This changes depending on the object being orbited. For orbiting satellites around theEarth, these two points are called the perigee and and the apogee. For other object the suffix changes to match that object being orbited.
These are the points in the earth's orbit at which it is closest to,
and farthest from, the sun, respectively.

What is the effect of aphelion on earth?
At aphelion, Earth receives 6.9% less of the solar radiation than at perihelion. Aphelion happens around July 4, so this means slightly cooler summers for the Northern Hemisphere and slightly cooler winter for the Southern Hemisphere..
How does the moon effect the earths seasons?
It doesn't
Does earths perihelion effect temperatures at the equator?
Obviously, being closer to the Sun, Earth will get more radiation. But the effect is not very significant.
How does the tilting of earths axis effect the earth?
it creates the seasons.
What was date the last earth was at perihelion?
In early January, during winter in the northern hemisphere, summer in the south, earth is at perihelion, closest to the sun. This is the opposite of aphelion, which is when the orbit of the Earth is farthest from the sun.
What would be the effect on earth if the planets axis were not tilted?
There would be no four seasons if the earths axis was not tilted.
How changes in earths tilt would affect seasonal patterns?
If there were no tilt then there'd be no seasons. So it has a direct effect.
Is the earth is closest to the sun during the month of august?
No. It is closet to the sun in January! Seasons are caused by tilt of the earth, not how close to the sun it is. But for which Hemisphere? Season are determined by tilt. The earth stays the same distance away from the sun every season.
What would be the effect on the Earth if the axis were not tilted?
There would be no four seasons if the earths axis was not titled.
When earth passes closer to the sun what does the climate become?
The difference between the Earth being closest to the Sun (called perihelion, about January 4) and the Earth being farthest away (aphelion, around July 2) is only about 3%. So there's not much of a climate effect at all.
What is the effect of rotation of earth?
The earths rotation causes day and night, wind, tides and ocean currents and its also responsible for the different seasons.
How would global warming affect fruit and vegetable seasons?
Because a change in the earths temperature can cause effect the way fruits and vegetables grow
