Solar Output
The activity that comes from the sun. This has decrease 0.1% since the 80s and is thought to be produced by the activity of sunspots
3 of 8
Orbital Geometry
The shape of the Earth's orbit around the sun causes glacial periods when the circuit is more circular and extreme warm periods when it is more elliptical
4 of 8
Volcanic Activity
Volanic erruptions release large amounts of sulfur dioxide into the atmosphere trapping in heat from the sun
5 of 8
Tectonic Activity
The movement of tectonic plates affects the global pattern of atmospheric and ocean circulation
6 of 8
Surface Reflection
When ice and snow reflect back the sunlight decreasing the temperature
7 of 8
Change in Atmospheric Gas
The release of methane and CO2 increase the greenhouse effect trapping heat within the atmosphere
