There are three different ways in which the Earth’s orbit changes throughout time. The changes in these orbits can have an effect on the Earth’s temperatures, causing cooling and warming cycles.
The first of these orbits is called eccentricity. The Earth’s orbit is not perfectly round; it moves in a more elliptical pattern. The degree of the planet’s ellipse is known as eccentricity. During this orbit, there are three times when the earth is closest to the sun than any other time. When the earth is closest to the sun during this orbit is perihelion and furthest from the sun it is called aphelion (Nelson, 2012).
Seasons on our planet are caused by the Earth’s titled axis. This tilt causes the top hemisphere of the planet to be closer to the …show more content…
The northeast hemisphere would be experiencing summer in aphelion. The planet’s obliquity cycle should be in the decreasing phase. The last of the variables is that the Earth would also need to be in the lowest phase of eccentricity. All three of these variables would put the Earth in position in which it would be receiving the least amount of solar radiation in the northeastern hemisphere. The Earth would be receiving the least amount of warmth.
Knowing how the orbits of the earth effects our climate, helps scientists see if global warming is occurring. Right now, the “Earth's Northern Hemisphere currently experiences its summer in aphelion, the planet's obliquity is currently in the decreasing phase of its cycle, and Earth's orbit is fairly near its lowest phase of eccentricity” (Nelson, 2012). This would mean cooler temperatures are should be the average, but we have been experiencing an increase in the average.
Understanding how the Earth’s orbits can affect the average temperature of the planet. Then we can take this data and compare it to what we expect to see based on the current orbital pattern. This can lead us to see whether or not global warming is having an effect on the average temperatures of the
