Sunspots on the Sun's Photosphere. This image came from NASA's Marshall Space Flight Center Solar Physics Lab . S cientists are only beginning to understand the myriad of factors that can result in climate changes.
Natural variations are the main reasons climate changes happen.
The Earth's climate is a dynamic system that is driven by the energy of the sun. Thus, we might conclude that variations in the sun's energy will change the climate. One way is sunspots and other solar events . These events can change the amount of energy being released by the sun. A nother way the sun's energy can vary is by variations in the Earth's orbit .
